It is possible to enjoy various services such as using the information and charging the selected terminal identification information.

Next, an apparatus on the communication line side of the IP telephone will be described.
(IP telephone communication line side device)
<DHCP server>
DHCP is a protocol that automatically assigns necessary information such as an IP address to a computer that temporarily connects to the Internet. The DHCP server is set with the IP address of the gateway server and DNS server, the subnet mask, the range of IP addresses that can be assigned to the client, etc., and these computers are accessed by means such as dial-up. Provide information. When the client finishes communication, the address is automatically collected and assigned to another computer. With DHCP, even a user who is not familiar with network settings can easily connect to the Internet, and a network administrator can easily manage many clients in a unified manner.
<DNS server>)
The DNS server is a computer system that converts a domain name corresponding to the name of a computer on the Internet into a string of numbers called an IP address corresponding to an address.

  Each name server has a correspondence table of domain names and IP addresses of computers connected to a network managed by the name server, and answers inquiries from the outside.

  There are innumerable name servers on the Internet, and it has a hierarchical structure corresponding to domain names. The name server located at the highest level is called a “root server”, and a plurality of servers are distributed throughout the world.

  Since a system in which name servers all over the world cooperate to associate a domain name with an IP address is called a “DNS” (Domain Name System), the name server is also called a “DNS server”.

  When searching for the IP address of a computer having the domain name “WWW.patent.co.jp”, the root server is first inquired.

  Since the root server answers the address of the name server that manages the entire “jp” domain, it sends an inquiry to the name server of the “jp” domain.

The name server that manages the "jp" domain also answers the address of the name server of the "co" domain, the name server of the "co" domain answers the name server of the "patent" domain, and the name server of the "patent" domain It returns the IP address of the computer “WWW”.
<NAT>
A function that transparently converts an IP address (local address) that can be used only within an organization and an Internet address (global address) to each other. With this function, a single global IP address can be shared by a plurality of computers in companies connected to the Internet. Global IP addresses that tend to be short recently can be saved.
<IP masquerade>
When converting a local address to a global address, it refers to the function of converting one local address to a global address with a port number. In this way, by identifying the communication port number and managing the correspondence between the local address and the IP address, a plurality of local nodes can communicate simultaneously with one global address.

As a result, it is possible to connect simultaneously from a plurality of machines with one global address. However, since the conversion to the port number is performed, there is a limitation that the connection from the Internet side to the internal machine cannot be started, and ICMP cannot be used. Some recent broadband routers have their own implementations to ease these restrictions.
<ENUM>
This is a protocol for converting a telephone number into a URI. By making the internationally unique telephone number system (called “E164”) established by the ITU (International Telecommunication Union) and a special domain area (subdomain of “.e164.arpa”) correspond to each other by DNS. Associate numbers with services and addresses on the net. There may be a plurality of addresses corresponding to one number. For example, if the user's telephone number is associated with an e-mail address, FAX number, Web site URL, etc. by ENUM, the telephone number can be used as a unified identification number for access means to the user.

The domain name of ENUM corresponding to the telephone number "03-1234-5678" is "8.7.6.5.4.3.2.3.2.1.1.8" in reverse order by replacing the leading 0 with the country code 81 of Japan. .e164.arpa ". The address corresponding to this DNS record is stored.
<SIP>
FIG. 7 shows a protocol of a SIP (Session Initiation Protocol) communication model which is one of standard call control protocols. First, a request message “INVITE” is sent from the calling side (S71). “INVITE” is a session activation signal, and an attribute of the session that can be received by the caller is indicated by SDP (Session DescrIPtion Protocol). Specifically, the reception condition (codec, port number, etc.) and transmission condition on the calling side are presented. The called side receives “INVITE” and transmits “180 RINGING” to the calling side in order to notify that it is in the calling state (S72). The “180 RINGING” may indicate the receiving condition (codec, port number, etc.) and the transmission condition on the called side, but it is normally indicated by the following “200 OK”. Next, “200 OK” is transmitted to the calling side to notify that the called side is ready to talk (S73). For this, the attributes of the session that can be received by the called party are shown in SDP. This “200 OK” presents the receiving condition (codec, port number, etc.) and transmission condition on the called side. Next, the calling side transmits “ACK” to the called side (S74), and thereby the attributes that can be used for communication are negotiated. In the present invention, this is defined as the connection phase for convenience. Next, transfer of media (sound, image, video, etc.) is started (S75). In the present invention, this data transfer period is defined as a data transmission / reception phase for convenience. When terminating the communication, the stop side sends a “BYE” signal to request the end of the communication (S76), and the side receiving it transmits a “200 OK” signal as a response to terminate the communication ( S77). In the present invention, this phase is defined as a cutting phase for convenience.
(Outline of mobile phone system)
Next, an outline of a mobile phone (mobile device) system will be described. The mobile communication system includes a mobile communication network having a plurality of mobile communication exchanges and a mobile phone. The mobile communication network includes an exchange network and a base station that actually transmits and receives signals to and from the mobile device. The mobile device and the base station communicate using a common control channel and a communication channel.

  Mobile phones are divided into generations according to the communication method with the base station, and mobile phones that have been marketed to date are roughly divided into three generations.

  The first-generation mobile phone (1G) is a so-called “analog mobile phone” that adopts the FDMA method, and it was a phone that was originally provided as a car phone in the 1980s, but was able to be carried around as it is. . First-generation mobile phones have already been discontinued in Japan, but are still being used in countries such as the United States.

  In the second generation mobile phone (2G), the digitization of communication and the adoption of the TDMA method were performed, and the use efficiency of radio waves was greatly improved. In addition, the weight reduction and price reduction of telephones have advanced rapidly in the second generation, and mobile phones have exploded in the late 1990s. The second generation communication systems include the PDC used by NTT DoCoMo and J-phone, and GSM widely used in European countries. Currently, it is almost mature. PHS is also a second generation communication system.

  In 1998, the CDMAONE service that adopted the CDMA system was started as a service called “2.5th generation (2.5G)”, which is a step forward of the second generation service. Around 2001, mobile phone carriers in various European countries started a GPRS service that enables high-speed communication of about 115 Kbps over a GSM network, and the development of a service that emphasizes data communication rather than telephone calls began.

  The 3rd generation mobile phone (3G) adopts the CDMA system, which enables conversations with less noise and interruptions, and enables high-speed communication that cannot be achieved with 2G, up to about 384 kbps even for data communication. Became. In the third generation mobile phone service, it is planned to provide a broadband service using a mobile phone based on a wireless communication network with higher quality.

  Services using mobile phones tend to diversify.

  The only service that was offered in the first half of 1G and 2G was a pure call service such as making and receiving calls. However, in the second half of 2G and 2.5G, short message service (SMS) between mobile phone subscribers started.

  Then, the mobile phone has been rapidly becoming an internet terminal, such as connecting to the Internet from a mobile phone to view a website or sending and receiving e-mail. The current mobile phone is a product that has become a more advanced Internet terminal. The mobile phone functions are compatible with music and video distribution services from the Internet, and some 3G services can be used as videophones. It continues to increase.

Furthermore, mobile phones equipped with functions such as digital camera functions, application software execution functions, or GPS functions that are not directly related to calls are also on the market. ) Is evolving into a device with a function as.
<Base station>
A device that communicates directly with a mobile phone and corresponds to the end of the mobile phone network. It is also installed on telephone poles, building rooftops, telephone boxes, and subway platform ceilings.

  Since the number of people who can make a call at a single base station is limited, two or more base station facilities may be located in the same place in busy places such as downtown areas.

  The range in which the mobile phone can communicate with the base station by radio waves is the so-called “call area”, and calls can only be made within this range.

In early PHS, when the user moved while talking, the radio wave of the base station in communication could not reach and the call was interrupted. In order to overcome this weakness, cellular phones and recent PHS have a “handover” function that switches the communication partner to the base station with the highest reception sensitivity as the terminal moves.
<Zone construction method>
In public mobile communications, it is generally necessary to cover a large service area and simultaneously accommodate a large number of subscribers. To achieve this within a limited frequency, the service area is divided into a number of zones (regions, cells). In general, a method is adopted in which each base station is installed in each divided zone, and the same frequency is reused in geographically distant zones to achieve effective use of the frequency. A method of covering a service area by dividing it into a plurality of zones in this way is called a small zone method or a cell method in contrast to a large zone method in which a single base station covers a wide service area. In the cell system, in addition to a method of configuring one zone using an omnidirectional antenna in one base station, a plurality of sector zones (sectors) are configured using a directional antenna in one base station. The method is also adopted. This has the advantage that the interference direction can be substantially limited to the directivity direction.
<Multi-channel access method>
In order for mobile stations and base stations to reduce call loss and use radio frequencies more effectively, in order to be able to use as many channels as possible without limiting the frequencies that can be used by mobile stations, A multi-channel access method is used. A method of allowing each mobile station to commonly own a plurality of radio frequencies and allocating and using vacant channels at the time of arrival and departure is called a multi-channel access method. Currently, with the development of frequency synthesizers using PLL (Phse Locked Loop), mobile devices that can be switched in units of thousands of channels have been realized at low cost.

As the multi-channel access method, FDMA (Frequency Division Multiple Access), TDMA (Time Division Multiple Access), and CDMA (Code Division Multiple Access) can be used.
<Location registration>
Since the mobile device moves across zones, it is unclear to which zone (area) it currently belongs. However, when a mobile device is called, it is inefficient to make a call from a base station nationwide in order to call one mobile device. The area is registered on the network side, and an incoming call to the mobile device is called only in which area. For this reason, when the mobile device moves beyond the location registration area, it is necessary to perform location registration from the mobile device to the network side. This is done in the following procedure.
(1) The mobile device recognizes that the area has been exceeded by receiving the location registration broadcast from the base station through the common control channel.
(2) The mobile station issues a location registration request to the mobile switching center via the base station using the common control channel.
(3) The mobile communication switching center updates the location registration of the mobile device in the home memory station on the network side.
(4) The mobile communication switching center notifies the mobile device that the location registration has been accepted via the base station.
<Incoming connection>
The mobile station normally receives the common control channel and waits for a paging signal for the mobile station itself. Connection control at the time of incoming call from a general telephone to a mobile device is performed as follows.
(1) A line is connected from a calling general telephone to the nearest mobile communication switching center A in the mobile communication network through the general telephone network.
(2) The mobile communication switching center A makes an inquiry to the home memory station and knows the location registration area of the mobile device.
(3) The mobile communication switching center A connects a line to the mobile station up to the mobile communication switching center B in the area, and calls the mobile station from all base stations in the area.
(4) In response to the call, the mobile device returns a response to the mobile communication switching center A via the base station, and specifies the base station where the mobile device exists on the mobile communication network side.
(5) On the mobile communication network side, a communication channel for the call is selected from unused communication channels, transmission from the base station side is started, and the mobile device is notified using the common control channel.
(6) When the mobile device switches to the notified communication channel and establishes communication, the wireless line connection control is completed.
<Outgoing connection>
Calling from a mobile device to a general telephone is performed according to the following procedure.
(1) The mobile device issues a transmission request to the mobile communication switching center via the base station.
(2) On the mobile communication network side, a communication channel for the call is selected from unused communication channels, transmission from the base station side is started, and the mobile device is notified.
(3) The mobile station switches to the notified channel and establishes a communication channel.
(4) The mobile communication switching center extends the line in the mobile communication network to the connection point with the nearest fixed telephone network of the other party's general telephone, enters the fixed network, and connects to the other party's general telephone through the fixed network.
<Handoff>
When the mobile device moves beyond the zone during communication, it is necessary to switch the base station for communication to the base station in the destination zone in order to connect the communication. This switching control is called channel switching during communication or handoff.

  There are several methods for detecting the zone shift of a mobile device. In the digital method adopting TDMA, the mobile device side uses a TDMA empty slot to measure and compare the reception level of signals from surrounding zones. The method is adopted.

After detecting the zone shift in the mobile device, handoff is performed according to the following procedure.
(1) Report the switching destination zone candidate from the mobile device to the network side.
(2) On the mobile communication network side, it is confirmed that there is a free call channel in the switching destination zone, and a channel to be allocated is selected from among the channels.
(3) The base station in the switching destination zone starts transmission of the channel and notifies the mobile device to switch to the channel via the communicating base station.
(4) The mobile device switches to the channel and establishes a communication channel with the base station in the switching destination zone.
<Authentication function>
In order to verify the legitimacy of the terminal, a cryptographic technique with increased confidentiality is used. A private encryption key is registered in the network and the terminal, and the network transmits a random number to the terminal. The terminal performs an operation using the random number and the encryption key, and returns the operation result to the network. The network verifies the validity of the terminal by collating the result of the calculation with the returned result. Only random numbers and calculation results are sent and received on the wireless section to ensure safety. Authentication is performed at the time of outgoing call from the terminal, at the time of incoming call, at the time of location registration request, and at the time of handover request.
<Wireless LAN>
A LAN that transmits and receives data by wireless communication. In particular, it often refers to a network composed of devices compliant with IEEE 802.11 standards.

  In an office with many layout changes, a lot of time and cost are spent each time the LAN cable is redrawn, but such a problem does not occur in the wireless LAN.

The transmission speed is not so fast as about 11 Mbps (in the case of IEEE 802.11B) compared to a wired LAN in which the 100 BASE 100BASE-TX standard is permeating.
<Internet>
A huge computer network that connects networks all over the world using the communication protocol TCP / IP.

  Its origin is said to be ARPAnet, a distributed computer network research project initiated by the US Department of Defense Advanced Research Projects Agency (ARPA). In 1986, a network NSFnet was established that links academic institutions based on the technology cultivated by ARPAnet. This was gradually used for commercial use from the middle of the 1990s and became the current Internet.

  In the days of academic networks, e-mail and NetNews were mainly used. However, with the emergence of the multimedia document system WWW equipped with a hyperlink function, the use in business and the use from home increased explosively. As a result, it has gained its position as an information and communication infrastructure of scale.

  The Internet is a decentralized network that does not have a computer that controls the whole, and is made up of server computers scattered throughout the world connected to each other and providing services little by little.

  Most of the services and applications provided on the Internet (from basic ones such as WWW, FTP, and e-mail to advanced ones such as credit card payments) are standardized protocols that do not depend on the model of TCP / IP. On the Internet, various computers can communicate across different models.

In order to participate in the Internet, it is necessary to connect to a network already participating in the Internet through a dedicated line. When connecting from a general household, it is necessary to make a contract with a contractor called an Internet service provider that accepts communication from a public line (such as a telephone line, ISDN line, or ADSL line) and connects to the Internet.
<WWW>
A standard document system used on the Internet and Intranet. It is possible to describe the logical structure and appearance of a document in a language called HTML, and to embed data other than characters such as images and sounds and the position (hyperlink) of other documents in the document. It has exploded in popularity since the mid-1990s as an Internet standard document system, and now a huge WWW network has been built on a global scale. It is the most frequently used application on the Internet.
<Hyperlink>
This is position information such as other documents and images embedded in the document. A system in which a plurality of documents and related objects such as images are associated using hyperlinks is called hypertext. The WWW is a representative example of hypertext. When a document is displayed by a Web browser and a link location is clicked with a mouse, it jumps to an associated link destination.
<Hypertext>
A document system using a computer. It is a mechanism that allows multiple documents to be linked to each other by embedding position information (hyperlinks) of other documents at an arbitrary location in the document.

  When a document is displayed using dedicated browsing software, the document can be displayed one after another by following links. There is also a system that can embed various information such as still images, moving images, audio, music, etc. in one document using the link function.

One of the hypertexts is the WWW, which is a huge document system built on the Internet.
(Mobile Centrex)
Currently, a system called Mobile Centrex is being developed. Mobile Centrex is generally a corporate telephone system that allows mobile phones (mobile Centrex terminals, hereinafter simply referred to as terminals or mobile phones) to be used as corporate extensions. Outside, it can be used as a conventional mobile phone. Since Mobile Centrex is just released, it has various problems and problems. The present embodiment solves these problems and problems.

  Conventionally, extension telephones of companies and the like had to install and operate a device called PBX (private branch exchange) in a building. However, in recent years, IP phones have been converted to IP to eliminate PBX and operate IP telephone servers. The “IP Centrex” contracted by carriers was attracting attention. Mobile Centrex also eliminates fixed telephones and line networks in buildings, and uses individual mobile phones as extension telephones. This eliminates the need for wiring work and PBX setting changes associated with relocation and layout changes, and eliminates the need to “take off seats” with mobile phones that are always carried around, and the need to relay telephones. You will always be able to contact people both inside and outside the office.

  The Mobile Centrex system includes a method (Method A) in which a mobile phone is equipped with a wireless LAN I / F and internal wireless LAN equipment is used to make an extension call, and a normal mobile phone is used. There are two methods (method B) in which a mobile phone provider (so-called communication carrier) in a company installs a wireless base station to realize an extension call. In addition, a method (method C) in which these methods are applied to a small-scale company or a home can be considered.

  There is also an IP Centrex that uses an IP phone instead of a mobile phone.

  It is a type of IP telephone service for companies provided by carriers, and is an outsourcing service that undertakes maintenance and operation of IP telephone servers.

  In a general company telephone system, an extension telephone network and an outside line are connected to a device called a PBX (private branch exchange) and controlled. Functions such as extension calls, representative calls, hold, and transfer are provided by PBX.

  In IP Centrex, the telephone system in a company is switched to an IP telephone, the PBX in the company is eliminated, and a call is made by connecting to a server provided by a communication carrier. This server (IP-PBX) provides the extension function and the like in the conventional PBX. The server is installed at the base of the telecommunications carrier, and a general data communication service used on the Internet or the like is used for communication up to that point.

  Since it is not necessary to install, maintain and operate a PBX or an IP telephone server that replaces the PBX, costs and personnel can be saved. In addition, since it can ride on an existing IP network (such as a LAN), there is no cost for laying an extension telephone network.

When bases are dispersed throughout the country, calls between bases are external calls in the conventional telephone system, but remote centers can be incorporated into the extension network in IP Centrex.
(Mobile Centrex (Part 1))
FIG. 8 shows a system diagram of the mobile center system A.

  The company 50 includes an office 51 and a head office 52, and the office 51 and the head office 52 are connected by a dedicated line (WAN) 53 or the like. The Internet is connected via a provider 54. LAN lines are laid in the office 51 and the head office 52. The IP-PBX 512, the SIP server 513, the presence server 514, and other servers (mail server, Web server, printer server, storage server, fireall, proxy server, etc.) ), Computers (personal computers, workstations, etc.) 517 and 519, wireless LAN base stations 516 and 518, routers 515, hubs, and other devices having LAN I / F (printers, MFPs, copiers, facsimile machines, scanners), etc. They are connected to each other via a LAN. The PSTN 56 is a general subscriber telephone network and provides a normal telephone (so-called fixed telephone etc.) service. The mobile phone carrier (mobile phone carrier) network 57 includes base stations (S) 572 and 573 and communication system equipment, and provides mobile phone services to the mobile phone device 574.

  Here, a device (wireless LAN base station, IP-PBX, each server device, etc.) that connects the calling device and the called device is called a base station side equipment device.

  The mobile phones 520, 521, and 574 of the system A can be used as VOIP phones (IP phones) connected to wireless LAN base stations (hereinafter referred to as APs or local base stations) 516 and 518 installed in the company, Outside the company, it can be used as a mobile phone connected to base stations (hereinafter simply referred to as base stations) 572 and 573 of a mobile phone company.

  When the mobile phone 520 makes a call with the mobile phone 521 via an extension in the office (extension phone call or extension call), the mobile phone 520 is connected to a nearby AP 518 and connected to a partner terminal via the IP-PBX 512. A call is made with the partner terminal 521 through A516. The IP-PBX 512 is a control device for controlling extension calls, and generally has a built-in SIP server function for controlling connection of IP telephones.

  In addition, conversion for connecting a normal extension telephone and an IP telephone is also performed. The SIP server function does not need to be built in the IP-PBX, and may be installed separately from the IP-PBX.

  The SIP server is a device that relays location information, call request, and response relay for call connection between SIP terminals.

  In-house, for example, when the mobile phone 520 makes a call on an outside line (outside line telephone or outside line call), it connects to a nearby AP 518 and connects to a general subscriber telephone network (PSTN or the like) 56 via an IP-PBX 512. (First outside line telephone or first outside line call). At this time, the IP-PBX 512 performs protocol conversion and data conversion for connecting the IP telephone to the general subscriber telephone network 56. As another method of outside line telephone, for example, a mobile phone 520 connects to an AP 518 and uses an in-house LAN via an IP-PBX 512, and a communication network (Internet, IP telephone) via a provider 54. Network, a general subscriber telephone network, etc.) and can talk (second external phone or second external phone call).

  Further, when the terminal is a mobile phone, it is possible to make a call by connecting to the base station of the communication carrier instead of connecting to the AP. For example, instead of connecting the mobile phone 520 to the AP 518, it can be connected directly to the base station 572 (a mobile phone call or a mobile phone call, simply referred to as a mobile phone or a mobile phone call) (third external line Call).

  Since there are various types of calling methods (dial method, outgoing call method) in this way, a more convenient method has been devised as a method for selecting the method to be used and a method for determining which method has been selected. There is a need to.

  The extension telephone is started when the calling device (the mobile phone on the caller side) dials (calls) the extension number of the partner device (the mobile phone on the phone receiver side). Here, the extension number is generally different from a telephone number (10 digits) used in a normal general subscriber telephone network or a telephone number (11 digits) used in a mobile phone network. The number of digits of the telephone number used is generally small (for example, 4 digits) (the smaller the number, the easier it is to make a call or the number is easier to remember). In a large company having several bases, a number indicating the base may be given before an extension number and used. Moreover, the case where an outside line number and an extension number are used as the same number is also considered. At this time, when dialing using that number, it is necessary to distinguish whether to use an extension or to use an outside line by something other than the telephone number (described later).

  On the other hand, the outside line telephone is started when the calling device dials the telephone number (outside line number) of the partner device.

  Also, in the case of a mobile phone call, the calling device is started by dialing the mobile phone number of the partner device.

  The IP-PBX determines whether the calling device is going to use an external phone or an extension phone (of course, another device may be used). As a method of determination, in the case of an outside line telephone, a method of dialing dial information in which a number or symbol having a predetermined number of digits is added to the head of the telephone number of the partner device (so-called 0 transmission is included in this method) There is. When the IP-PBX analyzes the received dial information and detects a predetermined number or symbol, or information corresponding to the number or symbol, the IP-PBX determines that the telephone is an external line. The number or symbol to be added is not limited to the beginning of the telephone number, and may be added in or after the telephone number. Also, in the case of an extension telephone, a number or symbol having a predetermined number of digits (a number different from the number or symbol used for an outside telephone) may be added to the other party's telephone number. Such a method can also be applied when the outside line number and the extension number are the same.

  As another method, there is a method of distinguishing between an external telephone and an internal telephone depending on the number of digits of the dialed telephone number. Since a general telephone number is 10 digits or 11 digits, if a dial number of 10 digits or more is detected, it is determined that the telephone is an outside line, and if it is 9 digits or less, it is an extension line. Alternatively, when 4 digits are used as an extension telephone number, an extension number may be determined if the number is 4 digits or less, and an outside line number if 5 digits or more are used.

  As another method, it is conceivable to perform an operation of instructing whether to use an outside line or an extension line when dialing.

  Another method is to determine whether the first number of the telephone number is 0 (a method different from the method of adding the predetermined number described above), and if it is 0, it is an outside line number. The telephone number is dialed as an outside line number as it is, and if it is not 0, it is dialed as an extension number. In this case, it is necessary to assign the beginning of the extension number so that 0 is not used, and it is necessary to input the outside line number without omitting 0. Recently, mobile phones have become widespread, one by one, and a method of inputting without omitting the area number (03, 045, etc.) has become established, so this method is quite effective. Compared with other methods, since the number to be input and other operations are not necessary other than the input of the other party's telephone number, it is one of the methods with the least number of operations.

  Also, when making an outside line call, it is necessary to determine whether to use the first outside line telephone or the second outside line telephone. In this case as well, a method of adding a predetermined number or symbol having a predetermined number of digits to the telephone number of the other party can be used.

  If the terminal to be used is a mobile phone and the terminal is in the office, there are cases where it is possible to connect to both the AP and the base station. Then, as a mode of making a phone call (external phone) that is not an internal phone, either of the two methods of connecting to an AP (first external phone, second external phone) or using a mobile phone connected to a base station. Can be selected. When making a call, it is necessary to determine whether the mobile phone is confident in determining whether to use the AP or the base station to make a call because the connected stations are different.

  As an embodiment of the determination method, the determination is made based on information input for operation by the operator. As a determination method, a number or symbol having a predetermined number of digits is added to the telephone number to be called (including the case where it is not added), and the first external telephone is based on the number or symbol having the predetermined number of digits. In this case, it is determined whether the call is made by the second external telephone or the mobile phone. For example, in the case of AP connection, a predetermined number or symbol having a predetermined number of digits is added, and in the case of base station connection, the other party's mobile phone number is dialed as it is. Alternatively, it may be possible to select either an AP or a base station as a dialing station before or after dialing.

  In another embodiment, the determination is made according to the telephone number of the party to be called. For example, if the telephone number to be called is an IP telephone number (050-), the call is made using the outside line (second outside line means) of the IP telephone. Thus, by performing communication using the same communication method as between IP telephones, for example, equipment such as protocol conversion in the middle is not used, so there is a possibility that the communication cost can be reduced.

  As another embodiment, there is a method of setting (can be arbitrarily set) an external line method to be used in advance. For example, when it is set in advance to use the first external telephone, when the telephone number of the other party to be called is input and the calling instruction is input, the first external telephone means Is used to make a call.

  When making a call from inside the company to the other party in the company using an extension, that is, when making a call using an extension telephone number, there is a problem that the telephone cannot be connected unless the other party (partner device) is in the company. . In particular, in the Mobile Centrex system, there is a problem in that the frequency of making a call with an external telephone number (especially a mobile phone number) increases from the beginning, and a telephone charge (calling charge) increases. As one embodiment of the invention for solving this problem, means for automatically switching between an extension line (extension means) and an outside line (external line means) will be described.

  First of all, there are two cases when a phone call is made: a person in the company (a person who works for the company) and another person (a person outside the company) (a person who does not belong to the company). External telephones (first to third external means) and internal telephones can be used for people in the company (in some cases, only internal telephones), while people outside the company only make calls using external telephones I can't.

  Therefore, the telephone number of the other party that the calling device makes a call is analyzed, and it is determined whether to use the extension line or the outside line based on the analysis result. The telephone number analysis device (AP, SIP server, call control device, IP-PBX, etc.) that has received the telephone number dialed by the calling device is first an internal telephone number or an external telephone number. Determine if there is. As a determination method, it is analyzed whether the received telephone number is an external telephone number or an extension telephone number. This can be determined by analyzing the characteristics of the external telephone number or the internal telephone number described above. As a result of the analysis, if the telephone number is an extension number, it can be determined that it is an in-house telephone number. If the telephone number is an external telephone number, the process proceeds to the next step. Next, an external telephone number used in the company is registered in advance in a telephone number correspondence table (external telephone numbers and corresponding extension telephone numbers are registered together with user names, etc.), and the telephone number correspondence table. And the received telephone number. When it is determined that the received telephone number is a telephone number outside the company, the telephone number is dialed by an outside line means.

  There are two cases where the telephone number received here is an outside telephone number or an extension telephone number as an in-house telephone number, and will be described below.

  Next, a case where the received telephone number is determined as an extension number will be described.

  The calling device is a case where the extension telephone number of the partner device is dialed to the AP device in the company, and the control device (AP device, SIP server, IP-PBX, etc.) in the company that has received the extension telephone number of the partner device ) Investigates whether the communication device of the extension telephone number is in the company (attended survey means). Specifically, the location registration server (having the same function as the home memory station of the mobile phone system) that stores the location of the terminal in the company is inquired about where the corresponding incoming call device is. As a result of the investigation, if it exists in the company, the AP device in charge of the corresponding area is instructed to call the corresponding counterpart device (second calling means).

  As a result of the investigation by the presence investigation means, if the partner device is not in the company, the telephone number correspondence table (the external telephone number and the extension telephone number of the terminal device in the company) stored in the storage device managed by the control device. Referring to the correspondence table), an external telephone number corresponding to the extension telephone number of the called device is obtained, and the external telephone number is dialed using the first external telephone means or the second external telephone means. To call out the other device outside the company.

  At this time, the base station side equipment device notifies the calling device of whether it is connected with an extension (or connected with an extension) or connected with an outside line (connected with an outside line), and the calling device that received the information Informs the information (for example, displays the information on the display unit).

  Moreover, the base station side equipment can manage the communication history by storing the call time when connected by an extension line and the call time when connected by an outside line. Each call charge can be calculated based on the information. In this way, by managing the external line call and the internal line call separately, it is possible to provide a service such as making the extension free or making a flat rate system.

  On the other hand, if there is no external telephone number corresponding to the received extension telephone number in the telephone number correspondence table, it can be determined that the telephone device is a telephone dedicated to the extension. Therefore, in this case, information indicating that the connection cannot be established (busy, busy, error, etc.) is notified to the calling device.

Next, a case where the received telephone number is determined as an in-house external telephone number will be described.
In this case, first, it is checked whether there is an extension telephone number corresponding to the external telephone number received with reference to the telephone number correspondence table. If there is no corresponding extension telephone number, the telephone number is dialed by the outside telephone means. On the other hand, if there is a corresponding extension telephone number, it is investigated whether or not the communication device of the extension telephone number is in the company (attended investigation means). It inquires the location registration server (having the same function as the home memory station of the mobile phone system) that stores the location of the terminal in the company as to where the corresponding called device is. As a result of the investigation, if it exists in the company, the AP device in charge of the corresponding area is instructed to call the corresponding counterpart device (third calling means).

  As a result of the investigation by the presence investigation means, if the partner apparatus is not in the company, the received outside line telephone number is dialed using the first outside line telephone means or the second outside line telephone means. By calling the partner device outside the company.

  As a mode of receiving a call when the terminal device is an incoming call device, an incoming call is received by an extension telephone, an incoming call is made via a provider, an incoming call is made from PSTN via IP-PBX (so-called dial-in, direct communication), There are four cases of incoming calls as mobile phones. Thus, when the terminal is a mobile phone, the extension number (ex. 1234), the IP phone number (050-), the dial-in (direct connection) number (030-), and the mobile phone number (090-) You can have more than 4 phone numbers.

  Therefore, there is a problem of which telephone number is notified among the plurality of telephone numbers when the caller ID is notified.

A method in which the base station side equipment device (communication network side) selects a telephone number to be notified and notifies the other side device (called side) will be described.
On the communication network side (AP, server, IP-PBX, small base station, small exchange, etc.), the external telephone number (dial-in number) of the mobile phone, the extension number, the IP phone number, the mobile phone number, the terminal in advance A correspondence table (phone number table in the figure) of identification numbers (mobile number, ID number, etc., phone number is also one of terminal identification numbers) is used as a phone number correspondence table for the number of mobile phones handled. I remember it.

  When a mobile phone on the calling side makes a call, it notifies the communication network side of the telephone number of the other party (called party) and at least one of the above-described telephone numbers (at least one of the above-mentioned plurality of telephone numbers). The above telephone number) or terminal identification number is notified. The communication network side receives the telephone number of the other party called by the mobile phone on the calling side and, if it is an extension telephone number, searches for the base station where the telephone number exists (in the location management server device) Inquire) Calls are made, and the extension telephone number of the calling-side mobile phone stored in the telephone number correspondence table is notified to the other party. If the other party's telephone number is an outside line telephone number, the outside line is used to make a call and the outside line telephone number (dial-in number, IP) of the calling side mobile phone stored in the telephone number correspondence table (Telephone number) or mobile phone number is notified to the partner device. Further, the communication network side may notify the two telephone numbers of the calling side outside telephone number and the extension telephone number stored in the telephone number correspondence table regardless of the received telephone number of the called party. .

  As another example of the caller ID notification, there is a method in which the mobile phone that calls itself determines the telephone number to be notified to the partner apparatus. Consider a case where a mobile phone can use two telephone numbers: a telephone number for an external telephone (a normal telephone number used as a mobile telephone) and a telephone number for an extension telephone. Assume that a four-digit telephone number is used as the extension telephone number. When making a call using an extension telephone number in a company, the other party's extension telephone number is usually called. In this case, since the extension telephone number is four digits, it is possible to determine that the mobile phone to be called is a telephone call or communication by extension telephone when calling with a four-digit telephone number. When it is determined that the call or communication is based on the extension telephone number, the telephone number of the own terminal apparatus notified to the other party or the communication network is the extension number of the own terminal apparatus. Further, when the telephone number to be called is not an extension telephone number (in the case of an external telephone number), that is, when the calling telephone number is, for example, 5 digits or more, it is determined as an external telephone number, and the external line of the own terminal device The telephone number is notified to the other party or the communication network. Or you may notify not only the telephone number to call but all the telephone numbers (two numbers of an outside telephone number and an extension telephone number) which an own terminal device has. The notified partner can know which number is the extension number or the outside number from the number of digits of the notified telephone number. Also, when making a call from outside the company (outside the area of the wireless base station in the company), the external line telephone number of the own terminal device is notified to the partner device or the communication network side.

  A plurality of wireless LAN base stations may be collectively regarded as one base station and communication control may be performed. In this case, one wireless LAN base station to be a host is set, and the other wireless LAN base station is controlled as a slave of the host wireless LAN base station. The host wireless LAN base station is a base station of a normal mobile phone. It behaves like

Further, by processing the call data and the data communication data as packet data, data communication can be performed using the Internet or a server even during a call.

  Further, the portable terminals 86 and 87, PCs 81 and 82, and the telephone 88 are connected to each other by the APs 82 and 83, various servers 84 and the provider equipment 85, and the PSTN 90, the provider 92, the SIP server 93, the Internet 94, and the mobile phone carrier. A network 96 can be used.

  When the mobile terminal 86 makes a call to the partner terminal 87 by extension at home, the portable terminal 86 is connected to a nearby AP 82 and connected to the partner terminal 87 via the provider facility (controller) 85 and the AP 83 connected to the partner terminal 87. Talk to 87. This provider equipment (controller) 85 is a control device for controlling a telephone call of an extension, and generally has a function of a SIP server that controls connection of an IP telephone.

  Further, when the mobile terminal 86 makes a call on the outside line at home (IP phone), it connects to a nearby AP 82, and connects to an IP telephone network (Internet) via an internal provider equipment (controller) 85 and an external provider 92. 94). Alternatively, the provider equipment (controller) 85 can perform protocol conversion from an IP telephone to a normal telephone and connect to the general subscriber telephone network PSTN 90.

  In places where public wireless LANs can be used, public wireless LAN wireless LAN base stations 100 (in FIG. 10, only one wireless LAN base station is shown, but in reality people such as stations and public facilities A wireless LAN base station exists at the facility where the user gathers, and can be used as an IP phone.

Next, the portable terminal is used as an IP phone by connecting to a wireless LAN base station installed in a home (which may be a small business or SOHO) or a wireless LAN base station installed in a public wireless LAN. A specific example will be described. Here, the case of using a communication carrier that provides a mobile phone service including a wireless LAN will be described with reference to FIGS.
<Location registration>
When receiving a signal (beacon) periodically transmitted from the wireless LAN base station 100 (S110), the mobile phone (mobile terminal) 99 requests location registration from the location registration server 101 via the wireless LAN base station 100. (S111). The location registration server 101 assumes that the mobile phone (mobile terminal) 99 has moved to the base station with the strongest radio wave or the base station selected by the mobile phone (mobile terminal) 99 as described below. Update registration and notify mobile phone to that effect. That is, by treating the wireless LAN base station 100 in the same manner as a normal base station, the wireless LAN system can be incorporated into an existing mobile phone system. The wireless LAN base station 101 operates as a miniature version (small version) of a normal base station. The protocol used between the wireless LAN base station 101 and the exchange is the same as or equivalent to the protocol used between the normal base station and the exchange (base station / exchange protocol), or a subset version of the protocol By using, the system can be constructed without changing the existing system. Of course, a dedicated protocol may be used.

  In addition, in order to perform location registration reliably or quickly, a connection with the wireless LAN base station 101 is started by operating a LAN button (location registration button, connection button, etc.) provided in the mobile phone 99. Also good. Alternatively, connection to the wireless LAN base station 101 may be attempted when charging of the mobile phone 99 is started (for example, when the mobile phone 99 is inserted into a charger).

  On the contrary, when the LAN line is congested (the communication speed may be reduced due to a call or other data communication, for example, the situation is such that the wireless LAN base station 101 notifies the situation from another device. The wireless LAN base station 101 may be controlled not to connect to the wireless LAN base station 101 when the wireless LAN base station 101 detects the line state and notifies the mobile phone).

  Returning to FIG. 11, when receiving a location registration request from the mobile phone (mobile terminal) 99, each base station responds to the mobile phone (mobile terminal) 99.

Upon receiving this response signal, the mobile phone (mobile terminal) 99 may display the location registration status or the connection status with the wireless LAN base station 101 and other information on the display unit of the mobile phone ( S112). Examples of connection status and other information include:
1. 1. Information indicating connection to LAN Information that the connection to the LAN is not possible (and why)
3. Information that there is no response from the LAN radio base station (base station failure, out of area, power off)
4). 4. Information indicating that the wireless LAN base station does not support the type of communication to be used (such as telephone call or data communication). 5. Information that the LAN radio base station is busy (no available channel), etc. Connected wireless LAN base station type (home, public, base station identification information or identification number)
7). 7. Protocol type and version information used in mobile phones and wireless LAN base stations 8. Information on the strength of radio waves of the wireless LAN base station Communication speed during communication (line speed)
10. Information (name, trademark, brand name, specifications, etc.) about the communication carrier that provides the wireless LAN base station
In addition, it is possible to assume that there are a plurality of base stations that can be used (a wireless LAN base station or a normal base station, or a plurality of usable wireless LAN base stations or normal base stations, respectively). May be displayed on the display unit of the mobile phone (icons, graphics, symbols, or text information are displayed in a list). The base station that can be used is determined based on being in the communication area of the base station (for example, being able to receive a beacon). Or the base station which exists in the periphery of the place based on the positional information acquired using the GPS function is displayed. In addition, the information of the base station may be the connection status and other information described above, or as other information,
1. Information indicating the currently connected base station.
2. Information indicating the recommended base station for connection (judgment based on call quality, signal strength, communication speed, etc.)
3. Information on the line usage fee (free or paid, usage fee per unit time or unit data amount, etc.).

  In addition, the base station that has registered the position and the base station that can register the position (the base station that has not yet been registered but detects the beacon) are displayed on the display unit.

  Returning to FIG. 11, look at the displayed information about the base station. The user determines whether to change the base station to be used (S113).

  If the base station to be used is not changed (No in S113), the process jumps to Step S115. When changing the base station to be used (Yes in S113), the base station to be changed is selected from the displayed base stations and transmitted to the base station. The selected base station updates the location registration of the mobile phone (mobile terminal) 99 to the location registration server.

  At this time, when the base station to be connected is selected and the connection is executed, the connection with the selected base station is started.

For the purpose of energy saving of the device, when the wireless LAN base station cannot be used, the power to the wireless LAN circuit of the mobile phone may be turned off. For example,
1. 1. When a beacon cannot be detected 2. When not connected to any wireless LAN base station When the terminal is out of the communication area of the connected wireless LAN base station. On the contrary, when charging the battery of the mobile phone, a wireless LAN circuit (a circuit for other functions may be used). ) May not be turned off.

If a plurality of beacons can be received, a plurality of base stations may be registered.
<Calling operation>
As described above, when a base station is selected in step 115 of FIG. 11, location registration is performed.

  At the same time, when a base station is selected in step 115 of FIG. 11, the other party, a mobile phone (mobile terminal) is specified for the selected base station, and a calling process is started ( S116).

  When calling processing is started, if the wireless LAN is in the area of a wireless LAN access point or small base station, the wireless LAN may be used for making a call or connecting for communication. The access point or the small base station may be preferentially connected, and when the access point or the small base station is not within the area of the wireless LAN, it may be connected to the base station. The above-described selection may be automatically performed by the apparatus, or a plurality of access points and base stations that can communicate with each other may be displayed on the display unit of the apparatus, and the operator may select a connection destination.

  Further, the base station to be used may be selected according to the application to be used (call, mail, Web). In addition, calls are made by ordinary mobile phones, calls by IP phones using VOIP, e-mail and short mail (simple mail using a call protocol), and Web by a communication carrier. There are various things, such as things connected to the general Internet. Therefore, for example, when transmitting by an e-mail application, it may be transmitted via a wireless LAN base station, and when transmitting by a short mail application, it may be transmitted via a mobile phone base station.

  Even if a call is made via a wireless LAN base station, if the LAN line is busy with another communication or cannot be used due to a predetermined failure, etc., the mobile phone base station is reconnected and the call is made. A call may be made. The reverse is also possible.

  Even when a call is made via a predetermined wireless LAN base station, if the base station is congested due to other communication, call should be made via another wireless LAN base station. Also good.

  In addition, as a reference for selecting a base station to be connected when a call is made, a communication line with a lower usage fee may be selected. In this case, it is determined based on usage fee information for each communication line (the information may be downloaded to the mobile phone in advance). Alternatively, the communication line to be used may be selected according to the identification information (identification number, telephone number, address information, etc.) of the partner apparatus to be connected. For example, when the other party's telephone number is an IP telephone number (050-), a wireless LAN base station is selected, and when the other party's telephone number is a cellular phone number (090-), a cellular phone is selected. Select a base station.

  The base station to be connected may be selected depending on whether the other party's telephone number is an emergency telephone number (110, 119, etc.).

  In addition, the ringing tone (callback tone), busy tone, ringing tone (ringing tone), and information displayed on the display unit may be changed according to the communication line to be used (there are the own device and the partner device). Good.

  Returning to FIG. 11, when the calling process is started, if the line with the selected base station is not crowded (No in S117), a call is made (S119). If the line with the selected base station is busy (Yes in S117), the base station is changed before making a call (S118, S119).

When a call is made, the communication partner is notified of the number (S119), and communication is performed (S120).
<During communication>
A case where communication lines are congested during a call and interference cannot be ignored will be described with reference to FIG. When communication is congested or during data communication (email, Internet communication) or when throughput (effective data speed) drops due to the influence of noise or the like (Yes in S121), other throughput is high. Switch to the communication line (S122). For example, if you are connected to a LAN line and the data transfer speed has dropped (the effect of communications with other PCs or mobile phones, the strength of radio waves, the number of communication errors, the number of data retransmissions), and so on, Try to switch. When the data transfer speed of the LAN line is restored (Yes in S123), the connection is returned to the LAN line (S124). Further, the switching information may be stored in the memory as a communication history, and may be read from the memory and displayed.

  In addition, multi-access is also possible in which data communication is performed via a LAN line and a call is made via a mobile phone base station (of course, a call may be made via a LAN line).

  Here, a case where the communication carrier providing the wireless LAN line and the mobile phone is a different company will be described.

When the wireless LAN line and the communication carrier that provides the mobile phone are the same, the wireless LAN base station can be handled in the same way as the mobile phone base station, so that one telephone number can be sent and received. A mobile phone has two phone numbers, a phone number for an IP phone and a phone number for a mobile phone. Therefore, when receiving a call, it is determined whether the call is received by an IP phone or a mobile phone depending on which phone number the other party calls. Further, when making a call, it is necessary to select which communication line is used. However, as described above, this is basically the same as the case where the communication carriers are the same. The difference is that it is necessary to select which telephone number is to be notified to the partner device when the communication carrier is different when the caller ID notification is performed. This is usually determined by the communication line used. For example, when making a call using an IP phone, the other party is notified of the phone number of his / her IP phone.
(Mobile Centrex (4))
Next, a system (scheme D) that can be used both in a company and at home with a single mobile phone will be described. FIG. 13 shows an example of a system diagram of method D. The system of FIG. 13 is a system in which a home network 60 is added to the system of FIG.

  A home network 60 is connected to the Internet 58 via a provider 59.

  In this embodiment, the provider 54 contracted with a company, the communication carrier (carrier of the network 57) providing mobile phone service, and the provider 59 contracted at home are different. In this example, a mobile phone communication carrier sells a mobile phone (at this time, a mobile phone number is assigned and can also have a plurality of mobile phone numbers), and the mobile phone An IP phone is used by using a wireless LAN interface provided, and a contract is made with a provider who connects a LAN line to the Internet, and the provider assigns the phone number of the IP phone. . Then, it is possible to use three telephone numbers: a telephone number (050-XXX) used for a company (company), a cellular phone number (090-), and a household telephone number (050-ΔΔΔ). A plurality of telephone numbers are set (assigned). These telephone numbers are managed by each provider or a mobile phone service provider. The management method is to associate the telephone number of each communication carrier with a unique identification number (mobile device number, manufacturing number, serial number, ID number, MAC address, IP address, etc.) of the mobile phone. is there. Since the communication carrier is different for each telephone number, the same identification number can be used. Accordingly, if the communication carrier can acquire the identification number of the mobile phone in the communication procedure, the communication carrier can know the corresponding telephone number from the identification number / phone number correspondence table. Or you may make it notify a communication number directly to a communication carrier in a communication procedure. If a method of notifying a telephone number is adopted, it is possible to assign a plurality of telephone numbers in one communication carrier or provider.

  A description will be given of how to select and use a plurality of own telephone numbers (the telephone number of the own device and the telephone number of the own station).

  First, when making a call and inputting the other party's telephone number from the input means, it is necessary to determine which of the plurality of own (own) telephone numbers to use before or after the input. select.

  When the other party's telephone number is selected from the telephone directory, a call is made using the telephone number set in advance for each telephone number of the other party registered in the telephone directory or the telephone directory.

  When the other party's telephone number is selected from the incoming call history, a call is made with the own telephone number that the other party has called for the incoming call. To do this, the phone number that the other party has called (the phone number that the other party dialed) out of the multiple phone numbers that the other party has called for each incoming call, and other incoming call history information (the other party's phone number, The received date and time, presence / absence of response, calling time, name of the other party, etc.) are stored in the incoming call history means.

  When selecting the other party's phone number from the outgoing call history, it is used when making a previous call, along with other outgoing call history information (the other party's phone number, outgoing date / time, presence / absence of response, calling time, name of the other party, etc.) Use your phone number that you remembered.

  Next, the case of receiving a call (when receiving a call) will be described. Normally, a call is received (received) at the telephone number dialed by the calling party. At this time, there is no problem as long as the mobile phone of the own device can receive a call with the phone number, but in a plurality of own phone numbers, a phone number that can be used and a phone that cannot be used depending on the location of the mobile phone. There is a number. If a call is received to a phone number that cannot be used, the call is transferred to a phone number that can be used. For this purpose, the base station side stores (registers) the identification number of the mobile phone number of its own device and a plurality of corresponding telephone numbers in the telephone number management means (telephone number management table, etc.), for each telephone number. , The status information of the phone number (information about whether the phone number can be used, information indicating whether the location is registered, status information (busy, busy, power off, presence information, etc.)), Updates are also made. After acquiring the telephone number on which the call has been received, the base station side searches whether the telephone number is stored in the telephone number management means, and if not, has an identification number corresponding to the telephone number. Call mobile phone. If stored, the status information is checked for the telephone number corresponding to the identification number corresponding to the telephone number, and the incoming telephone number is selected based on the result. For example, among a plurality of telephone numbers, a telephone number having a higher priority among the telephone numbers that can be used at that time is called. Since the call can be automatically transferred in this way, the chance that the call is not connected can be reduced.

Further, as a result of being charged for each telephone number by using a plurality of telephone numbers in this way, it is possible to manage communication charges for each purpose (for a company and for a private use).
In this way, when using a plurality of providers or mobile phone communication carriers, it is necessary to use a plurality of telephone numbers provided respectively. However, by roaming between providers or communication carriers, other providers You can use different provider phone numbers, or you can use multiple providers or communication carriers with one phone number.

  In addition, when these providers or communication carriers provide the service by a single communication carrier, each wireless LAN base station and mobile phone base station can be managed, and then the location registration of the mobile phone can be performed 1 Since it can be managed by one home memory, the telephone number can be unified.

  As a result, a plurality of telephones such as telephones used in a company, telephones used outside the office, telephones used in wireless LAN hotspots, telephones used in the home can be integrated into one telephone, It can be expected to improve usability.

A case where a single telephone number is used by a plurality of mobile phones is also conceivable. That is, there are cases where the telephone number is used as a representative number of the company, or when the telephone number is used as a common telephone number of the family in one household. In this case, identification numbers of a plurality of mobile phones are registered in one phone number on the base station side. When a mobile phone makes a call, the telephone number to be used is selected in the same manner as in the case of having a plurality of telephone numbers. When receiving a call to a mobile phone, the base station side may simultaneously call a plurality of mobile phones whose positions are registered and communicate with the mobile phone that responded first. Alternatively, priorities are set in advance, and a mobile phone with a higher priority is called from the mobile phones registered in position. At this time, if there is no response, the mobile phone having the next priority may be called.
(Mobile Centrex (5))
The method E described here is a case where the communication carrier that provides the wireless LAN line inside and outside the company, the communication carrier that provides the PSTN, and the communication carrier that provides the mobile phone are the same. In this case, the distinction between an extension and an outside line is not physical, but is determined by a contract.

  The outside line is a normal mobile phone call, and the extension is applied as a call between telephone numbers contracted as an extension. In other words, when an extension contract is made for telephone numbers A and B, calls or data communications between telephone numbers A and B are treated as internal lines, and communications between telephone numbers A or B and other telephone numbers are treated as external lines. Become. In other words, the difference between internal and external lines is mainly their communication charges. Then, the difference between the extension line and the outside line is not the difference in the hardware, but can also be regarded as the difference in the contract or fee structure. In other words, it can be said that a high fee structure is an external line, and a cheaper charge structure is an extension line. Further, when considering the scale of the system, as shown in FIG. 14, the largest system is an external line, and the system included in the system can be an internal line. Then, the system included in the extension can be called an extension, and a plurality of extensions can exist. Therefore, the outside system is an outside line when viewed from one extension line, and the outside line and the extension line are relative (in a broad sense) so that the system outside the outside line is an outside line when viewed from the outside line. it can.

  In general, an outside line is a general telephone subscriber telephone network (PSTN), and an extension is a company-specific communication line (WAN) that is built by the company or borrowed from a communication carrier. (In a narrow sense), there are some situations where the definition mentioned above must be used if it is strictly defined. It goes without saying that the invention described in this specification can be applied to all cases from the broad meaning to the narrow meaning described above.

Up to this point, the embodiment in the case of a telephone call has been described as the type of communication, but it goes without saying that it can also be applied to data communication. For example, there is an electronic mail as an example of data communication. In this case, the telephone number of the other party (called party) is the mail address of the other party and the telephone number of the calling party is the mail address of the calling party. The above-described technique can be applied by replacement. Also, when data is transmitted and received as data communication, the technology described above can be applied by replacing the other party's telephone number with a URI (or URL) and your own telephone number with your own IP address. It is.
<Call forwarding in mobile Centrex systems>
Since the Mobile Centrex system is intended to replace the conventional extension switching system, it is necessary to inherit the functions used in the extension exchange. An important function is a call transfer function.

  The transfer function means that, for example, a person who answers a call received on a representative phone hears the name of the person (transfer destination) who wants to call the person who made the call and calls the extension telephone of the transfer destination. It is a function to perform intermediary. Of course, it may be transferred not only to the extension telephone of the transfer destination but also to the external telephone.

The telephone used in the conventional extension exchange system is a so-called multi-function telephone (business phone), and has a large number of operation keys in order to realize the multi-function. However, since a mobile phone is used in Mobile Centrex, the operation keys that can be used are limited.
An object of the present invention is to realize a transfer function with good operability.

  There is a transfer method using a park function as a transfer method. The park function is, for example, picking up a call received at a representative telephone number (which may be a dial-in number or a direct number) with your telephone (for example, lifting your telephone handset (off-hook) and dialing a certain number A function that can transfer the incoming call to your phone), ask the person who made the call to hear the person you are relaying to, and temporarily hold the incoming call (for example, 1-9, hold number) The corresponding predetermined operation key is operated and put on hold, and the receiver is instructed verbally with the number held and placed on the handset (on-hook). When the destination partner presses the operation key corresponding to the notified number, he / she can talk with the other party who made the call. This feature has the advantage that you do not need to look up or remember the person's phone number. However, since the operation keys are limited in the mobile phone, there is a problem that it is difficult to provide a key dedicated to the park function.

  Therefore, as an embodiment of the present invention, a method of using a numeric keypad as a substitute for a dedicated key will be described with reference to FIG.

  There was an incoming call to the representative telephone number (which may be a dial-in number or a direct number) (S131). In order to pick up the incoming call with his telephone, the handset is lifted (off-hook) (S132), and then the numeric keypad (for example, 1) corresponding to the number to be held is pressed (S133). The information is notified to a call control device (for example, SIP server, IP-PBX, etc.) that controls the call, and the call control device checks whether the number is available (no other incoming calls are held at that number). (S134), and if it is available, the mobile phone picked up is notified of it. The mobile phone that has received the vacant information displays that fact on the display device (S136). The operator sees the display, tells the relay destination the number that is held, and hangs up (S137). When the destination person presses the numeric keypad corresponding to the number on hold and presses the response button (off hook) (S138), the held incoming call is transferred to the destination telephone and the call is started (S139). ). If the number designated when the call is put on hold is not available, the call control device notifies the fact (S140). The picked-up mobile phone displays the notified information on the display device.

  As another example of the park function, a command (command) for holding the picked-up incoming call is notified to the call control device, and the call control device receiving the command is free to hold. The number is checked, one of the vacant numbers is determined, and the number is notified to the mobile phone. The mobile phone that has received the vacant number displays the number on the display unit, and when the operator performs an operation for deciding to hold the number, notifies the call control device of the decision to hold. The call control device that has received the hold decision information puts the incoming call on that number on hold.

  Further, when the call is picked up, the call control device may notify the mobile phone picked up of a vacant hold number.

  However, the park function has the disadvantage that the call cannot be forwarded unless the agent is nearby. As a transfer method that compensates for this drawback, a method of transferring directly by inputting the telephone number of the destination can be considered (direct transfer). However, this direct transfer also has a problem that it is necessary to remember the telephone number of the transfer destination, and when it is not remembered, there is a problem that it is printed on paper and the telephone number of the transfer destination must be found from the telephone table.

  Therefore, as an embodiment of the present invention, when a call received from a representative is picked up, a candidate list of transfer destination telephone numbers (a list in which a telephone number is associated with the name of the owner) is stored in a mobile phone. An example of display on the display unit will be described with reference to FIG.

  In a large company, there may be many employees on one floor of the company, and when all the employee telephone lists are displayed at that time, it becomes difficult to find the telephone number of the transfer destination person. Therefore, by limiting the phone numbers that can be picked up (actually grouping a plurality of phone numbers), the number of phone numbers in the transfer destination candidate list can be limited. In the grouping, a telephone number is registered in the telephone directory 61 provided in advance in the mobile phone, and a flag (transfer flag) indicating a transfer destination is added.

  When the representative number is received (S141) and picked up (S142), the telephone directory 61 is referred to and a list of telephone numbers to which a transfer flag is added is displayed (S143). When the transfer destination telephone number is selected and transfer is executed (S144), the transfer destination telephone number is dialed (S145). Thereafter, it is confirmed that the transfer destination has responded (S146), and when the telephone is hung up (on hook: S147), the apparatus that made the call and the transfer destination apparatus are connected, and the transfer process is completed.

  In this case, it is necessary to check whether the forwarding destination has answered (you can check if you have answered by calling the forwarding destination) (if you hang up before the forwarding destination answers, you can call If you want to omit confirmation by calling with the forwarding destination, there is a problem that it is difficult to disconnect yourself. Therefore, when the call control device detects the response of the transfer destination, the call is connected to the transfer destination and the transfer is automatically completed regardless of whether the picked-up mobile phone disconnects the call. Alternatively, immediately after calling the forwarding destination telephone number (even if the forwarding destination has not yet responded), the call control device puts the call on hold, and the call that was put on hold when the forwarding destination answers. May be connected to the transfer destination.

  The park function and transfer function described above can be applied not only to a call that arrives at a representative telephone number, but also when a call arrives at a dial-in number (direct number) assigned to each mobile phone. That is, the operation after the response to the incoming call can be applied to the operation after the pickup of the incoming call to the representative telephone number.

  Also, even if the user of the telephone returns after picking up the telephone that was directly dialed in, it is necessary to enter and transfer the extension number of the picked-up telephone, which is inconvenient . Therefore, in the present invention, an embodiment that solves the problem will be described.

After picking up, press a certain button to return. At this time, when a call is received by dial-in, since the IP-PBX or SIP server stores the telephone number received by dial-in, the extension number corresponding to the dial-in telephone number is stored. By searching the telephone number table in which the correspondence between the dial-in number (external line number) stored in the means and the extension number is searched, the target extension number can be found. Therefore, the IP-PBX or SIP server transfers the telephone to the extension number searched and found. Then, the picked-up operator can return the call without remembering the phone number.
(Automatic transfer function)
The transfer function described above involves a person (person who has received a call), but it can also be performed automatically.
When a call comes in to a representative phone, the representative phone may be in use (during a call, data communication, etc.). Because it is busy, the normal system returns a busy tone to the other party that made the call (actually, the other party's exchange sends a busy tone), so the call is concentrated. There is a problem that the phone does not connect. The present invention solves this problem. This will be described with reference to FIG.

  If a call is received from a representative telephone (a predetermined number is registered in advance in IP-PBX as a representative telephone number) (S151), if the representative telephone is not in use (No in S152), a call is made Is performed (S154).

  However, when the representative telephone is in use (Yes in S152), the IP-PBX inquires of the presence server device about the state of the telephone (fixed telephone, mobile telephone, IP telephone, etc.) corresponding to the representative telephone number ( S153: This inquiry may be made periodically, and the status information may be cached in advance in the storage device of the IP-PBX, and of course, the IP-PBX may have the function of a presence server. Here, when the telephone cannot be used during a call, the telephone having a telephone number registered in the IP-PBX in advance (usually an extension telephone number, but an extension telephone number or an external telephone number can also be used). The presence server device is inquired about the status of Such inquiries can be made as many times as there are registered transfer destination telephone numbers. In response to the inquiry, if there is a notification from the presence server that it can be used (Yes in S155), the IP-PBX calls the telephone (S156). If the telephone answers the call, the incoming call is connected to the forwarding telephone (S158).

As another example, the telephone number managed by the IP-PBX or the telephone number registered in advance as the representative number or transfer destination number is inquired, and the telephone that has responded to the inquiry is inquired. Calls are made according to the priority order registered in advance. This inquiry uses an inquiry protocol.
If the destination phone is also assigned a dial-in or direct phone number, or if it also has a mobile phone phone number, it can be distinguished whether the call has been made directly or has been transferred. There is no problem. Therefore, in order to distinguish between the above-mentioned transfer and a normal direct incoming call, the ringtone type can be set separately. In addition, the display may be changed so as to be distinguished. The IP-PBX transmits a call signal for calling a telephone to be called with information for distinguishing between normal incoming call and transfer. The called telephone determines whether it is a normal incoming call or a transfer based on the type of the call signal received from the IP-PBX or information included in the signal.
At this time, if the answering machine provided in the IP-PBX is set to operate, the answering machine can be used when the representative telephone cannot be used or when there is no other telephone that can respond. Record the caller's message by activating the function. Alternatively, the recorded message may be transmitted by calling a telephone number registered in advance.

An example when the main phone is busy is shown, but it cannot be used for some reason (for example, when it is out of order), or the main phone is a Mobile Centrex phone and you go out with it, or as a mobile phone It can also be applied when used (during a call, during data communication, etc.).
(Presence function)
Presence function refers to the status or status of a mobile phone user (for example, being present, on the phone, going out, eating, meeting, going home, etc.) registered in the presence server, and the status ( Status).

  In the conventional presence function provided by Mobile Centrex, a mobile phone user registers his / her status in the presence server by using an extension communication line. Therefore, the presence function is a service that uses a dedicated communication line for an extension, and the telephone number to be used is managed by the extension number, so it cannot be used among general users who use a public communication network. The present invention solves such a problem.

  An embodiment of the present invention will be described with reference to FIG. A communication carrier that provides a mobile phone user with a communication network installs a presence server connected to the communication network (wireless LAN line, mobile phone network, etc.). A cellular phone implements a protocol for using the presence function. In the presence server, telephone numbers for external lines (mobile telephone numbers, IP telephone numbers, etc.) of a plurality of users who use the presence function are registered as one user group (S161). Group registration and group telephone number registration can be done from each mobile phone using a registration protocol. The mobile phone notifies the presence server of an inquiry signal and a telephone number of the device itself to make a presence inquiry (S162). Upon receiving the inquiry signal and the telephone number, the presence server searches whether the telephone number is registered, and if it is registered (Yes in S163), it is registered in the group to which the telephone number belongs. The presence information of the telephone having the telephone number is notified to the telephone inquiring (S164). The telephone that has received the presence information displays the received presence information on the display unit (S165). If this presence information is composed of hypertext (page description language) such as HTML (XML, HTML, SGML, XHTML, CHTML, HDML, DHTML, BML, etc.), versatility is enhanced. Then, since the Internet can be used as a communication line, the presence function can be used even by a user who is far away. If a mobile phone is equipped with a Web browser, presence information can be displayed on the browser and many Web servers can be accessed via the Internet. Further, by creating a common phone book in hypertext and storing it in the common phone book server, the phone book can be used in common. In addition, the common telephone directory may be expanded to include presence information together. It can also be viewed from a PC (personal computer) or a computer having a Web browser for browsing the page description language described above. In this case, a known authentication technique (for example, authentication using a password or a public key) can be used for authentication.

  There are two types of status registration (or status update and presence information update) in the presence server: automatic registration and manual registration. The types of statuses to be automatically registered include those based on the location information of the mobile phone (at home or going out) and those based on the usage status of the mobile phone (during a call or waiting).

  First, a specific example of status automatic registration based on position information will be described.

  “At home” is a status indicating that the wireless LAN base station is within the reach of radio waves. Specifically, if the mobile phone is within the reach of radio waves from a wireless LAN base station (which may be a mobile phone base station) installed in the home, the presence status is set to “at home”. When a mobile phone that catches a beacon transmitted by a wireless LAN base station installed in the mobile station performs location registration, the mobile phone is at home. On the other hand, when the location registration is changed as the position of the range of the base station of a normal mobile phone beyond the range where the radio wave of the wireless LAN base station reaches by going out, it goes out.

  Specific examples will be described below. First, in the presence server, position information (identification information attached to the wireless LAN base station or the base station, information related to the position information, etc.) and a name corresponding to the position information (for example, “home”, “outing”, “company”) "Location where radio waves do not reach" "Yokohama Station" "Shinjuku" "Parent" "School" "University" "Public Facilities" "Kanagawa Prefecture" "Atsugi City" etc.). The registration method connects to the base station in a state where it enters the cell of the registered base station. Thereby, the location registration is updated. Next, the registration work is started by connecting to the presence server via the base station. At this time, when a name corresponding to the base station is input from the operation unit of the mobile phone and a registration operation is performed, the presence server inquires the location registration server for location information and obtains location information. The acquired position information and the input name are associated with each other and stored in the storage device.

  Next, the update of the presence status will be described. Since the location information of the mobile phone is managed by the location registration server, the presence server inquires of the location registration server about location information of the mobile phone (such as wireless LAN base station or identification information attached to the base station). Next, the location information received from the location registration server is compared with a plurality of location information registered in advance in the presence server (names are respectively set), and the corresponding status (name) is determined based on the result. It is to be updated. Alternatively, even if the matching position information is not registered in the presence server, for example, if the acquired position information is other than “home”, the status may be “going out”.

  Next, a specific example of status automatic registration based on the usage status of the mobile phone will be described. The usage status of the mobile phone includes “busy”, “data communication”, “sending”, “receiving”, “calling”, “calling”, “powering off”, “charging”, and the like. If you want to check the status such as “busy”, “data communication”, “outgoing”, “receiving”, “calling”, “incoming”, etc., the presence server controls the call control or communication control. This can be done by inquiring a device (SIP server, call control device, base station side device, etc.) about the communication status of the mobile phone. Statuses such as “powering off” and “charging” can be performed by the presence server inquiring directly to the mobile phone.

  Up to this point, the mechanism in which the presence server updates the presence information has been described. Conversely, the location registration server, the communication control device, or the mobile phone may send a presence information update request to the presence server. In addition, this update may be performed periodically, or after a predetermined event occurs, the update operation may be started by making it a decision.

  Next, manual status registration and update will be described.

  Any status can be defined for this. For example, statuses such as “meal” and “sleeping” are registered in the presence server in advance. Next, the cellular phone and the presence server are connected by communication, and a status registration or change request is notified to the presence server by operating the cellular phone. The presence server receives the request and reflects the presence information.

Since the provided functions differ depending on the type of mobile phone, the statuses that can be automatically registered also differ. Therefore, status information is registered according to the provided functions. As an example, in the case of a landline telephone (a telephone that is not a radio telephone), statuses such as “charging”, “data communication”, “going out” cannot be registered.
<Application of presence function>
Using the presence function described above, it is possible to determine the operation of the station side device (communication line side device) or the own device. That is, when a certain predetermined event occurs (for example, a change in the state related to communication control such as incoming or outgoing), the operation of the communication line side device or the own device is determined according to the status state in the presence function. Is.

  For example, when the status is “on the phone” and there is an incoming call, the device on the communication line side confirms the status, and if the status is “on the phone”, do not connect to the terminal device. To. Alternatively, at that time, the answering machine function of the line side device is activated to record or store the calling side message. Alternatively, even if the communication line device confirms the status of “in-phone” (it does not have to), it connects to the terminal device and notifies the incoming call. On the terminal device side, when the status is “calling” in the terminal device settings, the operation is “answering machine”, so the answering machine function is activated in response to the incoming call, and the calling party message is recorded. Or it is something to remember.

  In the case of an incoming call with a status of “in-call”, if there is an incoming call from a member in the group using the presence function, the terminal device setting is “answering”, and the group In the case of an incoming call from other than the above, the operation of the apparatus may be determined by making different settings such as “ringing a ringtone and receiving an incoming call”.

  FIG. 19 shows an example of setting the operation of the communication line side device and the operation of the terminal device corresponding to each status.

  In other words, when the status is “on the phone”, the line control device may perform one of the following operations: disconnect, record, connect, and return a busy message. May not respond, record messages, or not ring.

  Further, when the status is “out of office”, the line control device may perform one of the following operations: transfer, answering machine, not connected, and return message indicating that the user is out. Sometimes, the terminal device may perform either transfer or absence recording.

When the status is “Attendance”, the line control device connects the line. At this time, the terminal device may perform any one of a response, a ringing tone, and an absence recording.
(Power saving function)
The present invention uses an impact sensor, an acceleration sensor, particularly a triaxial acceleration sensor, for the purpose of power saving of the device.

A three-axis acceleration sensor is a sensor that detects acceleration, tilt, and vibration in a three-dimensional space by dividing it into three axis components (X, Y, and Z axes). This 3-axis accelerometer has high sensitivity and can measure gravity (acceleration 9.8m / s ² ) in a stationary state. Therefore, it is possible to detect instantaneous (f ≦ 200Hz) acceleration from the detection of tilt. This acceleration sensor detects acceleration, tilt, impact, etc. in the three axes (X, Y, Z) directions, and enables measurement of tilt angle and vibration in addition to acceleration.

  Mobile phones are increasingly equipped with high-performance applications that support users by detecting movement, such as location information services using GPS (Global Positioning System). However, the geomagnetic sensor currently used to add azimuth information to position information has an insufficient accuracy because an error occurs depending on the angle at which the mobile phone is held. In portable devices such as portable music players with built-in hard disk drives (hereinafter referred to as HDDs), hard disk damage due to falling is a problem. Therefore, it is possible to correct the orientation information error by sensing the tilt, and even if the device falls in any posture, the fall is sensed by acceleration, and the magnetic head is attached to the disk before the HDD receives an impact. There was a need for a three-axis accelerometer that could be evacuated to a safe area outside to avoid damage to the HDD. The acceleration sensor uses the piezoresistive effect to detect acceleration, tilt, impact, etc. in three axes and outputs this signal digitally.

  In this embodiment, as shown in FIG. 20, the output result of the acceleration sensor is analyzed (S166), and a device such as whether the user touches the mobile phone, holds it in the hand, or is operating. Determine the state. As a result of the analysis, if the output has no acceleration, no change in tilt, no impact, etc. (or a combination thereof), the device is stationary (the user is not carried around, The energy saving operation is started or the energy saving operation is continued (S168). If there is an output (or a combination thereof) such as acceleration occurring, tilt changing, impact occurring, etc., it is determined that the device is moving (No in S167), If the energy saving operation has been performed at that time, the energy saving operation is canceled and control is performed to return to the standby operation (S169).

  As the energy saving operation, the operation of the CPU is stopped, the HDD is stopped, the display is turned off, the display is turned off, the operation key is turned off, the number of position registration attempts is reduced, the base station (wireless LAN base station, There are a reduction in the strength of radio waves transmitted to a mobile phone base station, a reduction in power supply to a predetermined circuit (especially a circuit that consumes much current during standby), and the like.

  In addition to the output result of the acceleration sensor, the change over time of the output (output pattern of the acceleration sensor output), the date and time at that time, time information, and the operating state of the device at that time (executing the specified function, waiting) State or energy saving state), or by controlling the device or energy saving control by predicting what state the device is in by a memory storing the operation state of the device.

  Here, the location registration process of a mobile phone will be described as an example of energy saving.

  When the mobile phone is in the cell and the location registration is successful through the base station, the next location registration is attempted after a certain amount of time. In addition, when it goes out of service area, it tries to register the location immediately in order to find a base station that can communicate. In this way, if there are many location registration attempts, the number of processes to receive a beacon for location registration increases, and naturally power consumption also increases. Therefore, the smaller the number of location registration trials, the lower the power consumption and the better the battery life.

Therefore, the present invention changes the number of location registration trials according to a predetermined condition. That is, when it is not necessary to increase the number of location registration attempts (for example, when a mobile phone is not used), the number of location registration attempts is reduced. As the parameters of the predetermined condition, the output of the acceleration sensor, time information (time information, day of the week, date and time information), information on communicable base stations, etc. are used. For example,
1. Decrease the number of registrations according to the length of time that the mobile phone is not operated. Whether it is not operated is determined by analyzing the output of the acceleration sensor or the impact sensor. Or you may judge by the input of an operation key.
2. In a predetermined time zone (for example, from midnight to morning), the number of registrations is reduced.
3. The number of registrations is reduced on a predetermined day of the week (for example, Sundays and holidays).
4). If it is within the area of the home memory station, the number of registrations is reduced (or increased).
Further, instead of changing the number of location registration attempts, energy saving may be performed by changing the strength of the radio wave transmitted to the base station.

In order to improve security, the operation of the mobile phone may be locked instead of or together with the transition to the energy saving mode described above. In addition to the operation of the mobile phone, the lock target may be locked for each function, such as prohibition of outgoing calls, prohibition of telephone book operation, and prohibition of operations related to electronic money.
(Missed call notification function)
When there is a missed call (when there is an incoming call but no response operation is performed) (normally it is an incoming call, but it may be a mail reception or push signal reception), the incoming call lamp is lit regularly By doing so, the user is notified that there is an incoming call. However, if the incoming call lamp is turned on regularly, the battery is consumed correspondingly, which is contrary to energy saving. Such a problem of the present invention is solved.

  Therefore, this problem is solved as shown in FIG. When there is an incoming call (S171), the output of the acceleration sensor or the impact sensor is analyzed to determine whether it is absent. If it is not absent (No in S172), an incoming call notification is performed. However, if it is absent (Yes in S172), the fact that there is an incoming call is stored in the storage device 62 without performing incoming communication (S173). Then, it is detected whether the user touched the apparatus by detecting the movement of the apparatus with an acceleration sensor or an impact sensor. When the movement of the device is detected (Yes in S174), the storage device 62 is referred to, and if there is a missed call, the user is notified (S175). The notification method includes vibration by a vibrator, lighting or blinking of an incoming lamp or backlight, and ringing by a ringing means. Further, it is possible to know what kind of notification is made by changing these notification patterns (patterns such as ringing, lighting, and vibration) according to the type of incoming call or reception.

  Further, once the number of notifications is notified, the notification may not be performed thereafter. Moreover, you may alert | report every time the motion of the apparatus mentioned above is detected. In this case, the notification is terminated by another predetermined operation.

  If the information indicating the missed call displayed on the display unit is accessed, or if it can be presumed that the notification is surely confirmed by simply operating the operation button, the subsequent notification may be stopped. .

  The types of movement of the apparatus include acceleration generated in one direction or multiple directions, inclination of the apparatus, rotational movement of the apparatus, vibration of the apparatus, and the like.

Movement pattern (type of movement)
1. Acceleration works from the stationary state up: out of pocket Regular up and down movement: walking, running 3. Acceleration down: Drop 4. 4. Regular or continuous impact: operation key operation Unique impact: Fold open, close 6. Rotation (90 degrees, 180 degrees, 270 degrees, 360 degrees (1 rotation), multiple rotations)
In this way, notification is made only when the apparatus is operated, and notification is not made periodically, thus saving power.

  Further, the present invention can be applied not only to missed calls but also to other functions that notify the user.

  In addition, there is a case where it is not possible to answer a call even if a call is received while driving a car. At that time, the control of the apparatus may be changed according to the number of impacts on the apparatus, the intensity of the impact, and the length of the impact.

For example, when you receive a phone call
One impact: The ringing sound that was ringing in response to an incoming call (incoming call) is stopped.

        2 consecutive times: Stop ringing and answer incoming call.

3 consecutive times: Stop ringing, answer incoming call, send a message (for example, can't answer the phone, please wait for a while). Instead of the number of times of impact, the above-described operation may be performed according to the strength of the impact or according to the length of the impact.
Further, instead of the impact, rotation (90 degrees, 180 degrees, 1 rotation, multiple rotations, etc.) may be detected and the above-described operation may be performed.

Further, the output of the sensor corresponding to the movement of the device described above is stored, the output information and the control operation of the device are registered in advance, and the control operation corresponding to the movement of the device is set. You may do it (learning function).
(Intelligent speed dial method)
Speed dial means that when a predetermined short number (for example, 01) is input and a call button (off-hook button) is pressed, the other party's telephone number previously associated with the short number is called (the telephone number is dialed). Send). However, to find out which abbreviated number the abbreviated phone number is registered to which of the abbreviated numbers, for example, check the phone book where the other party's name, phone number, abbreviated number, etc. are registered, Alternatively, there is a method of searching for the abbreviated number using the search function of the phone book, but all of them are troublesome and troublesome to operate.

  The procedure for calling a telephone number by speed dial is performed by first entering a short number using a numeric keypad in a standby state of the mobile phone and then pressing a call button. In conventional mobile phones, the input abbreviated number is merely displayed as the display on the display unit at that time.

  An embodiment of the present invention will be described with reference to FIG. In the standby state of FIG. 22A, when the first number (usually the highest digit) of the abbreviated numbers is input from the numeric keypad, one or more abbreviated numbers belonging to the number and the abbreviated number Is displayed as a list of the name, telephone number, mail address, and other items in the telephone directory. For example, if the first number input is 0 assuming that abbreviated numbers can be used from 00 to 99, a list of abbreviated numbers from 00 to 09 is displayed as shown in FIG. At this time, the input number is displayed together with the list. If the black inverted triangle is pressed, the screen scrolls downward.

  In addition, whether or not to display a list of abbreviated numbers may be set for each abbreviated number.

  In FIG. 22B, when 1 is further entered, the short-circuit number “01” is selected, and the screen shown in FIG. 22C is displayed. On this screen, the call button (or the execution key or off-hook may be pressed) is pressed. Then, the screen shown in FIG. 22D is displayed, and the telephone number registered in the abbreviated number is dialed.

  If a number of 3 digits or more is entered, it is a normal dial operation that is not a speed dial. For example, if “1” is further input on the screen of FIG. 22C, the screen of FIG. 22E is displayed, and a normal dial operation can be performed.

  In FIG. 22B, instead of inputting “1”, a desired abbreviated number among a plurality of abbreviated numbers displayed in a list and related information (telephone number, name, mail address, etc.) You may make it select by operating a cursor key etc.

  In FIG. 22C, when a mail button is pressed instead of a call button, mail can be transmitted.

  When the display screen is small and not all lists can be displayed at once, it is handled by scroll display. Further, the list of abbreviated numbers after 10 may be displayed in a scroll display. Next, when the second number is input, a list of only the confirmed abbreviated numbers may be displayed, or a list of a plurality of abbreviated numbers is displayed and the abbreviated abbreviated number part is displayed. The area may be selectively displayed (inverted display etc.). At this time, when the execution key is pressed, the telephone number corresponding to the selected abbreviated number is dialed. If the third number is entered without pressing the Enter key, the entered number is determined to be a normal phone number, and the list of abbreviated numbers is cleared and only the entered number is displayed. It may be.

Also, if the execution key (e-mail key) is pressed after entering the abbreviated number by associating the abbreviated number with the e-mail address, a new e-mail creation screen containing the e-mail address at the destination is displayed. You may make it make it.
(Number portability)
The system that keeps the identification number (telephone number, e-mail address, URI, etc.) unchanged even if the mobile phone operator with which the contract is made is called number portability or number portability, or MNP (mobile number portability). .

As a method for realizing this, when a certain identification number has been changed to a contract of another operator, a mechanism for passing communication to the change destination operator is required. Therefore, each business operator newly prepares a transfer information database that lists an identification number and a business operator to which the identification number has been transferred. When there is communication for an identification number whose contract has been changed, it is connected to the changed business operator based on the transfer information database. The connection method includes the redirection method shown in FIG. 23 and the transfer method shown in FIG.
Redirection method (1) The calling terminal sends the telephone number (090-abcd-efgh) transferred from the transfer source operator A to the transfer destination operator B.
(2) The device BS1 of the originating network (the network of the operator C) notifies the telephone number of the called terminal to the exchange EX1 of the originating network.
(3) The exchange EX1 of the originating network connects to the exchange EX2 of the transfer source network and notifies the telephone number of the called terminal.
(4) The exchange EX2 of the transfer source network inquires whether the telephone number of the called terminal that has received the notification is stored in the transfer information database.
(5) The exchange EX2 of the transfer source network notifies the transfer information EX as a result of the inquiry to the exchange EX1 of the transmission network.
(6-8) The exchange EX1 of the originating network connects to the called terminal via the exchange EX3 of the destination network and the base station BS2 based on the transfer information.

Transfer method (1) The calling terminal sends a call to the telephone number (090-abcd-efgh) transferred from the transfer source company A to the transfer destination company B.
(2) The device BS1 of the originating network (the network of the operator C) notifies the telephone number of the called terminal to the exchange EX1 of the originating network.
(3) The exchange EX1 of the originating network connects to the exchange EX2 of the transfer source network and notifies the telephone number of the called terminal.
(4) The exchange EX2 of the transfer source network inquires whether the telephone number of the called terminal that has received the notification is stored in the transfer information database.
(5) The exchange EX2 of the transfer source network transfers the call to the transfer destination network based on the transfer information of the inquiry result, and notifies the exchange EX1 of the transmission network of the transfer information of the inquiry result.
(6, 7) The exchange EX3 of the transfer destination network connects to the called terminal via the base station BS2.

  This embodiment will be described with reference to FIG.

  The difference in configuration from FIG. 23 is that, in the redirection method, the exchange EX1 of the transmission network includes a transfer information database 2 that stores transfer information. In the transfer method of FIG. 24, the same can be implemented even if the exchange EX1 of the transmission network includes the transfer information database 2 for storing the transfer information.

  In this transfer information database 2, the transfer information notified in (5) above (the telephone number (transfer source telephone number) transmitted by the transmission network, the operator or network of the transfer destination, the number of history information (reference), etc.) Next, when there is a communication for calling the same telephone number, the above (2) to (5) are omitted, and the transfer destination operator is directly connected.

  In addition, information stored in the transfer information database 2 is cached by a memory (a storage method whose access speed is faster than other storage means, or a storage method that is distinguished from other information and devised so that access is particularly fast). You may make it memorize.

  Further, even if the telephone number to be dialed is the number initially contracted by the transmission network operator (C operator in the example), it may be confirmed by the transfer information database 2 as in the above-described example.

  Also, the transfer source business operator can quickly redirect or transfer a phone number that is frequently connected or inquired by storing the transferred phone number in a caching memory.

  In this way, by using the transfer information database 2, the time required for redirection or transfer can be shortened, and the destination can be connected more quickly.

  In addition, each operator (A, B, C operator) uses a relocation method or transfer method to transfer information database to each operator, and a common transfer information database (including all transfer information of each operator). 71) may be used in common as shown in FIG. Alternatively, each operator has a transfer information database separately. As shown in FIG. 27, for example, the transfer information database 72 of the operator A is copied and the businesses of B and C are copied so as to always have the same data. The transfer information databases 74 and 74 may be used. Then, the time required for redirection or transfer can be shortened, and the destination can be connected more quickly.

  FIG. 28 shows an example of information stored in the transfer information database. The database shown in FIG. 28 stores information on the first change, the second change, the third change,... According to FIG. 28, the number “090-abc-efg” was originally a number served by the operator A, but thereafter, the number was changed to a number served by the operator B. .

In addition, when the telephone number of the called terminal is redirected or transferred at the relocation destination (for example, the B business operator), it is checked whether the telephone number has been relocated to the relocation destination itself (the B business operator own If the phone number DB managed as a phone number is searched and it has been transferred to itself, it is connected to the called terminal, and if it has not been transferred, information to that effect is redirected (transfer information is transmitted) This is notified to the operator (in this case, the operator A) or the transferring operator.
(Display of broadcast programs and web pages)
In addition to analog broadcasting, there is broadcasting for mobile objects such as mobile phones (one-segment broadcasting) performed by terrestrial digital broadcasting.

  In Japan's terrestrial digital broadcasting system, one channel is divided into 13 “segments”, and several of these are bundled to transmit video, data, and audio. High-definition broadcasting (HDTV) requires 12 segments, but normal-quality broadcasting (SDTV) requires only 4 segments, so three different programs can be broadcast simultaneously on one channel.

  One of these segments is reserved for mobile broadcasting, and one-segment broadcasting is performed using this segment. Because the bandwidth is as narrow as 1/4 of normal broadcasting, only low-resolution video of QVGA (320 x 240 pixels) size can be transmitted, but a new attempt can be made using the communication function and location information by taking advantage of the characteristics of mobile terminals. .

  H.264 is used for video encoding. H.264 (MPEG-4 AVC), and AAC LC is used for audio encoding. Still images support JPEG, GIF, and animation GIF. As a copyright protection technology, scrambling was initially considered, but it was postponed, and copy control using CCI (Copy Control Information) was used. The data broadcasting part can describe information by BML. As an extension unique to One Seg, it is possible to link with e-mails, schedule books, GPS position information, etc. of the mobile terminal.

  There is a rule that a broadcast program and a Web page (content provided by a trader other than the trader that provides the broadcast program) cannot be displayed simultaneously. Then, if the application is started up whenever necessary, it takes time to start up and is not practical.

  Therefore, in this embodiment, as shown in FIG. 29, both a broadcast program application for receiving and displaying a broadcast program and an application for displaying a Web page (so-called Web browser) are started (S201, In step S202, a selection is made (S203), only the display of one application is displayed, and the display of the other application is turned off (S204). Or, if you are in a multi-window display and you are viewing one, hide the other behind it and display a small icon corresponding to that display in the corner of the screen or in the icon bar for icon display. It is something to keep. To switch between windows, select the window directly behind or click the icon.

  Further, a numeric key of a numeric keypad may be associated with the icon, and an application screen of an icon corresponding to the numeric key may be displayed when the numeric key is operated.

  Or in the portable terminal device provided with two or more screens, the received broadcast program may be displayed on one screen, and the Web information may be displayed on the other screen. At this time, if a predetermined operation is performed, it is convenient to be able to exchange display screens.

  Broadcast programs and videos can be easily viewed on mobile terminals through stream data distribution via TV broadcasting, the Internet, or communication carrier services. Next, a business model of advertisement (CM) will be described with reference to FIG.

  First, a business model (so-called push type) in which an advertisement provider (such as a mobile phone communication carrier or a content provider) that provides an advertisement to a mobile terminal owned by a user sends the advertisement will be described. An advertising provider contracting with a user who owns a mobile terminal pushes advertisement data (video, still image, URI indicating the location where the data is stored, etc.) to the mobile terminal based on the contract conditions or periodically (S211). The user who receives the advertisement data activates and views the advertisement data provided in advance in the mobile terminal (S212). Or you may make it receive the application for reproduction | regeneration with advertisement data. At this time, although depending on the contents of the contract, the line usage fee for receiving the advertisement data is free (it may be low), so that many users can easily conclude a contract. Specifically, information indicating that the data is advertisement data or information indicating that the amount is low or free is added to the header of the packet data, and the communication fee is determined based on the information of the header.

  The advertisement provider receives an advertisement fee from the advertiser. This advertisement fee is calculated based on the number of times the advertisement data is transmitted to the user and the number of times the user views the advertisement data. The number of times the user views the advertisement data is stored in a predetermined area (an area for storing history information) of the advertisement data or the reproduction application. In addition to the number of times the advertisement data has been viewed, this area stores user information such as the date and time of viewing, information on the portion viewed, and data input by the user. When a predetermined period has passed, the advertisement provider collects advertisement data or a reproduction application, reads history information viewed by the user from the collected data, and calculates an advertisement fee based on the information. Alternatively, the mobile terminal may itself transmit history information to the advertisement provider in response to a request from the advertisement data or the reproduction application. The advertisement fee may be a flat fee regardless of the number of transmissions.

  Also, if the advertising provider is a mobile phone communication carrier, by discounting call charges and data communication charges based on the number of times advertisement data was sent to the user and the number of times the user viewed the advertisement data, You can increase the number of advertising contracts.

  Next, a pull type embodiment will be described with reference to FIG. In this case, the user downloads the advertisement data from the server of the advertisement provider by himself or the user's setting.

A menu for downloading advertisement data is selected from the menu of the portable terminal (S213). When the menu is selected, a list of addresses (URL, URI, etc.) where advertisement data is stored is displayed (S214). Next, when one of these addresses is selected (S215), A list of advertisement data stored at the address destination is displayed (S216). When the advertisement data is selected (S217) and a download start is instructed, the advertisement data is downloaded to the storage unit of the portable terminal (S218). ). It can be expected that a large number of users can be acquired by making the communication charge related to this download lower than the normal charge or free of charge. The communication fee is discounted for both downloading the advertisement and searching for advertisement data in a predetermined directory of the server device and receiving information related to the advertisement data. The advertisement provider counts the number of times the advertisement is downloaded, calculates an advertisement fee based on the count result, and charges the advertiser. Alternatively, as described in the push type, the mobile terminal stores history information related to the advertisement data, notifies the advertisement provider of the information, and calculates the advertisement fee based on the information. Good.
(Automatic bookmarks)
Search engines are provided on the Internet. When it is desired to display Web pages searched in the past again, there are only methods for registering in a bookmark provided by the Web browser or searching for a target Web page by inputting the same keyword. The former method cannot be used when a bookmark is not added or forgotten to be added. In the latter case, there is a problem that it takes time and effort to find out.

  Therefore, in the present embodiment shown in FIG. 32, the above-described problem is solved by using the search history. That is, when searching for a Web page using a search engine in a Web browser, a history of keywords input to the search engine is stored in the storage unit 76 (S221). The data to be stored are the first input keyword (basic keyword), the keyword (additional keyword) further input to the search engine until reaching the target web page, and the text or image data input for the search) As a result of the search by the keyword, the URL of the Web page selected by the user (that is, link information) in the Web page that is listed, and the URL that is selected in the Web page that is the link destination (that is, to follow the link) All the URLs selected in the above), the time spent on the Web page, and the data input to the Web page are stored. The history information is associated with the basic keyword. In this way, a plurality of basic keywords and corresponding history information are stored in the storage means of the own device.

  Next, when a keyword is input to the search history information display input means (S222), the basic keyword of the search history information is searched for the same keyword (S223). Is displayed (S224). When a predetermined URL is selected (S225), the Web page of the URL is displayed (S226). When displaying history information, the order of URLs to be displayed is determined and displayed based on data stored as history information. That is, a Web page targeted for keyword search is estimated and information such as the URL of the page is first displayed. Parameters for determining the order include the time spent on a Web page (if it is longer, the target Web page is more likely), the fact that a predetermined input has been made (that something has been input means that the page is the target page There is a high possibility that

  Further, the search history information may be displayed when a keyword is input to the search engine. In this case, the search result is displayed by the search engine, but the search history information may be displayed in a different display (for example, a different display window is displayed).

  When displaying the search history information, in addition to the URL, the time spent at the URL, the date and time of use, information about the Web page (title, summary, excerpt, image, etc.), etc. are displayed.

  If all URLs are displayed when the search history information is displayed, URLs that are not required (such as simple link addresses for reaching the target Web page, URLs that are used but not required for searching), etc. If it is displayed, the display screen becomes complicated and difficult to use. Therefore, an unnecessary URL is estimated (estimated based on how to follow the link when searched) so that the URL is not displayed. For example, the URL when the staying time at the URL is extremely short, the URL of all the links traced so far when the staying time is short on the terminal link destination Web page, and the like are not displayed.

The search history information may be edited.
(Download TV broadcast programs and videos)
Recently, it has become possible to use optical fibers even in ordinary households. With the increase in the communication speed of optical fibers, TV broadcast programs can be viewed and videos can be downloaded. However, as the number of users to be distributed increases, the load on the server to which the broadcast program is distributed increases, and it is necessary to prepare a higher-speed server device or increase the number of server devices, resulting in higher operating costs. There are challenges.

  Therefore, as an embodiment of the present invention, a casting grid system will be described as a method for distributing a TV broadcast program.

  In the casting grid method, broadcast program data and moving image data of TV broadcasts are distributed from the server device to the user receiving device (SB (set box)), and data is successively transferred from the SB to other SBs by the bucket relay method. To be transferred. The advantage of this method is that it is not necessary to prepare a server device for high-speed processing as compared with a method for delivering all data to all SBs by itself.

  Here, paying attention to the SB installed at home, the higher the communication speed of the communication line used in the SB, or the higher the SB image processing capability or communication processing capability, the higher the received broadcast program. Data can be transferred to many SBs (SB transfer capability). Therefore, the usage fee (basic fee, fee corresponding to the amount of data used, etc.) for watching TV broadcasts or downloading broadcast programs or moving image data is changed according to the number of SBs at the transfer destination. If the number of SBs to be transferred increases, the load on the server device decreases. For example, if the number of SBs to be transferred is large, the usage fee can be reduced.

  In addition, if the number of SBs at the distribution destination increases, it is necessary to receive more confirmation signals as to whether or not the distribution is successful, and there is a problem that it is necessary to increase the speed of the server device.

  Therefore, the server device does not receive the confirmation signal from all the SBs, but only the terminal SB, that is, the SB that does not need to be transferred next, transmits the confirmation signal to the server device. In this way, whether the SB in the middle has correctly received the data is the SB related to all the SBs transferred by the SB, and all the SBs at the end returned a reception OK signal to the server device. In this case, it can be estimated that the SB is correctly received.

  This casting grid method is premised on a high-speed communication line like an optical fiber, but can also be applied to a device using next-generation high-speed wireless communication (for example, Wi-MAX).

  A service other than normal calls is PTT (PUSH TO TALK). While pressing the dedicated button, you can send voice data to the other party, which can be used as a transceiver. You cannot speak at the same time as the other party as you normally do. However, voice data can be sent to a plurality of opponents. However, there is still a problem that is not convenient.

  The PTT according to an embodiment of the present invention uses a simple protocol as compared with a normal call, thereby realizing a simple call. For example, PTT is realized by sending voice data directly to the partner apparatus without securing call control for performing a normal call and only securing a logical channel (possibly omitting securing a logical channel in some cases).

Next, an embodiment of the present invention for PTT will be described.
1. The other party (selecting name, telephone number, address, etc.) to converse with PTT is selected from the telephone directory of telephone B (phone A).
2. Speak into the microphone while pressing the PTT call button. The call ends when the call button is released.
3. The telephone A is notified of the call, the telephone A rings and the voice from the telephone B is reproduced.
4). Speak while pressing the call button on phone A.
5. A ringing tone sounds on the telephone set B, and then the voice from the telephone set A is reproduced.
At this time, if you want to switch to a normal call while performing PTT, if you operate the switch button on the telephone, you can call the normal telephone number of the other party of PTT at that time, It is possible to perform call control of a call and call the other party's telephone to make a normal telephone call (both can be talked simultaneously). At this time, in the case of one-to-one PTT, since there is only one partner, it is only necessary to call by that telephone number. However, when there are a plurality of PTT partners, a plurality of telephone numbers corresponding to the other party are displayed, You may make it call by selecting a number.

  Conversely, if a switching operation to PTT is performed during a normal call with the other party, the PTT mode is entered thereafter, and conversation with the other party is possible.

In a normal telephone, there is a history means for storing outgoing records and incoming records, but in the case of PTT, outgoing and incoming histories (partner sights, telephone numbers, call dates, etc.) can be stored.
Also, if you receive a PTT when you are making a normal phone call or when you are unable to hear PTT messages directly while performing other operations, the incoming call history is stored and the PTT voice Store data in memory. Further, a display indicating that there has been an incoming call is displayed on the display unit. When the display is selected, the PTT conversation mode is entered and the stored PTT voice data is reproduced. After that, by pressing the PTT call button, it is possible to make a call using the PTT to the partner apparatus that has received the incoming call.

  By making it possible to easily switch between PTT and normal telephone in this way, it is possible to provide convenient usage that matches the usage conditions of the user.

  In addition, when a PTT is called for a predetermined telephone number (a telephone number that cannot be used with PTT) such as an emergency telephone number such as 110 or 119, or a special service telephone number, it is automatically Alternatively, the call may be made by switching to a normal telephone.

  In addition, during a call with a plurality of opponents using PTT, control may be performed so that only the other party who has selected one or more of the plurality of opponents can hear the voice he / she has heard. The partner is selected by selecting, for example, the displayed telephone number or display information (character, icon, symbol, character, image information, animation, etc.) corresponding to the telephone number.

  A case where a call is received during PTT will be described. If there is an incoming call to a device (usually the calling device) that has the caller's right (the one that the calling device has, for example, the PTT ends when the caller ends (disconnects) the call) When answering a phone call, PTT usually ends, so before answering the phone call, the caller right is handed over to one or more of the other callers who are PTT. In this case, the selection method as described above can be used for the selection of the counterpart device. A normal call may be made in response to the incoming call (calling) after passing the caller's right. On the other hand, when a telephone call is received by a device that does not have a caller right during the PTT, a normal call is made after leaving the PTT by responding as it is. Display information on one or more partner devices participating in the PTT (including its own device) is displayed on the display unit on the PTT calling or called device, and the device status display (no response to PTT call) , PTT participation, withdrawal during PTT, calling device, caller's right, etc., and characters, icons, symbols, characters, image information, animation, etc. corresponding to such display) are displayed, and the status of the device is You may make it change a status display whenever it changes.
