Specification

Network device, communication terminal, network system, and route notification method

The present invention relates to a network device, a communication terminal, a network system, and a route notification method.

Background art

[0002] In Japan, in addition to conventional landline phones and mobile phones, the number of IP telephones such as 05 OIP (Internet 'protocol) telephones and Hikari telephones using ADSL and optical fiber has rapidly spread, such as over 10 million. I am doing. In recent years, FMC (Fixed and Mobile Convergence) has been attracting attention as a technology that improves the usability by making use of the characteristics of these network networks and integrating them together, and has been actively discussed in Japan for its realization. Yes.

On the other hand, overseas, the Korean KT has already started providing services as OnePhon e service, which is a form of BT power FMC service. This is a service that integrates mobile phone and landline phone terminals. It is used as a mobile phone terminal outdoors as in the past, and only when a mobile phone terminal is brought indoors, it is a Bluetooth access point. This is a service that calls as a landline (or IP phone) via

[0004] In addition, mobile phone number portability has been introduced this year. In order to use each company's unique services, a contract with that company is required, but until now the mobile phone number has been taken over, so the contract with the previous company has been maintained and the mobile phone has been maintained. In many cases, the phone number was left and multiple mobile phone numbers and multiple mobile phone terminals were used properly. Number After portability is introduced, mobile phone service can be received even if the mobile phone number currently in use is contracted with another mobile phone carrier.

[0005] As a connection method for number portability, a redirection method is used for connection from the mobile phone network to the mobile phone network, and a transfer method is used for connection from other than the mobile phone network to the mobile phone network. Adjustments are being made to achieve this. Note that the redirection method is the routing of the sender business operator to the transfer source business operator. In this method, the source operator collates information indicating the relocation destination with the database and verifies the result to the originator, thereby performing direct routing to the source operator. The transfer method is a method in which routing is performed from a source company to a transfer source company, and the transfer source company transfers information to the transfer destination company based on information indicating the transfer destination. The combined use method is a method in which a provider uses a redirection method or a transfer method. These number portability technology and the FMC service technology described above are based on routing and forwarding, and many parts are common.

[0006] Further, as a mobile phone terminal characterized by a phone number, a mobile phone terminal having a plurality of phone numbers has been devised for business and private use (see Patent Document 1 and Patent Document 2). ).

Disclosure of the invention

Problems to be solved by the invention

[0007] However, when the OnePhone service such as the one started overseas is realized, the caller is connected via any communication line when making a call to the user of this service. It becomes impossible to recognize the power of. One of the features of the OnePhone service is that users do not need to be aware of what kind of communication line they are connected to. Current telephone users can use them in various ways depending on the type of communication network. In many cases, inconvenience may occur if it is not recognized. For example, in cordless phones and analog mobile phones, avoid conversations with high confidentiality in consideration of the possibility of interception. If the caller does not answer the call, it is assumed that the other party is not present on the fixed phone and the call is placed again for a while. When it is multiplied again, it looks like.

[0008] As described above, the OnePhone service has a problem in that it is impossible for a power sender to recognize what communication line the destination is connected to, and inconvenience occurs.

[0009] Also, with the introduction of mobile phone number portability, contracts with different mobile phone operators Even if it is changed, it is possible to take over the mobile phone number currently used and receive the service. However, for users who already have contracts with multiple mobile phone operators and have multiple mobile phone numbers, number portability has the advantage that contract operators can be combined into one company. It is not possible to use your mobile phone number ^^. Some users who currently have multiple phone numbers have made additional contracts to use services unique to other operators, but existing contracts with operators that have been used so far may be cancelled. It is assumed that there are many users who continue to make contracts because it is complicated or difficult to inform the person who needs to change the mobile phone number.

As described above, there is a problem that aggregation of a plurality of mobile phone numbers cannot be solved even by introducing number portability.

An object of the present invention is to provide a network device, a communication terminal, a network system, and a route notification method that are convenient for the user in consideration of the technical trend that FMC services and number portability are introduced. That is.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0019] (Embodiment 1)

FIG. 1 is a block diagram showing a configuration of a network system according to Embodiment 1 of the present invention. In the figure, reference numeral 10 denotes an FMC compatible mobile phone terminal, which is connected to a fixed network crossing 12 via an FMC home adapter 11 which is also a Bluetooth access point. Reference numeral 13 denotes a gateway exchange, which connects the fixed exchange network 14 and the mobile exchange network 15 to each other. Further, the mobile phone terminal 10 communicates with the BTS (wireless base station device) 20 wirelessly outdoors (that is, outside the area of the FMC home adapter 11), via the RNC (wireless network control device) 21 and through the MMS. (Mobile switching center) Connected to 22. 30 is the mobile phone used for outgoing calls It is a telephone terminal that performs wireless communication with BTS 31 and is connected to MMS 33 via RNC 32. A fixed telephone terminal 40 is connected to the fixed network exchange 41.

[0020] As shown in the figure, a network consisting of a network system, BTS20, 31, RNC21, 32, MMS22, 33, mobile switching network 15 and fixed network switch 12, 41, fixed switching network 14 and FMC It consists of a fixed network consisting of a home adapter 11.

The fixed network intersection 12 that is a fixed network device arranged in the fixed network includes a communication line selection unit 50 and a number notification unit 51.

[0022] The communication line selection unit 50 responds to a connection request for a communication terminal power that can be connected to a fixed network in which the own device (fixed network switch 12) is provided, and performs a plurality of communication routes to the communication terminal of the transmission destination. Select one communication path. The communication line selection unit 50 selects a communication path via the MMS 22 which is a mobile network device when the terminal detection unit 58 included in the FMC home adapter 11 for the destination communication terminal power related to the connection request does not detect. The communication line selection unit 50 manages the location state of the communication terminal in the area of the FMC home adapter 11, and notifies the transfer setting to other fixed network switch or MMS according to the location state and transfer. It has a function of managing the destination telephone number.

[0023] The number notification unit 51 notifies the source fixed network switch or MMS of the information of the selected communication path, and the notified communication path information to the source communication terminal. And a function to send a new incoming request to the fixed network switch or MMS corresponding to the notified communication path information. The number notification unit 51 notifies the information of the selected communication path to the communication terminal that is the transmission source. In this way, the user of the source communication terminal can check which communication route is used for communication with the destination communication terminal. In addition, the number notification unit 51 notifies the information of the selected communication path to the source communication terminal only when the communication line selection unit 50 selects a communication path different from the communication path related to the connection request. May be. In this way, since a notification is received when a communication path that is not intended by the user of the communication terminal of the transmission source is selected, the user can select to perform the communication, and can also respond to the communication path. You can also communicate. In addition, since this does not require notification in all cases, the amount of system traffic can be reduced. [0024] The communication path information to be notified includes communication path identification information corresponding to the selected communication path (for example, a communication path via a cellular system or a communication path via a fixed network). Or the telephone number information of the destination communication terminal corresponding to the selected communication path (for example, an FMC compatible mobile phone terminal has a telephone number in the mobile network and a telephone number in the fixed network). Therefore, you can use the phone number corresponding to the selected route.

[0025] The FMC home adapter 11 functions as an access point when the FMC compatible mobile phone terminal 10 communicates via a fixed network. The FMC home adapter 11 has a terminal detection unit 58 that detects a communication terminal existing in an area covered by the FMC. Communication terminals that can communicate via the FMC home adapter 11 are limited. For example, it is limited to communication terminals owned by the family in the home where the FM C home adapter 11 is installed. That is, the terminal detection unit 58 detects whether or not a predetermined communication terminal exists.

[0026] The MMS 22, which is a mobile network device arranged in the mobile network, includes a communication line selection unit 52 and a number notification unit 53 that function in the same manner as the fixed network switch 12.

[0027] The communication line selection unit 52 responds to a connection request from a communication terminal that can be connected to the fixed network in which the own device (MMS22) is installed, and among the plurality of communication paths to the destination communication terminal. Select one communication path. The communication line selection unit 52 selects a communication path via the fixed network unit 12 which is a fixed network device when the connection to the destination communication terminal related to the connection request is not established.

[0028] Number notification unit 53 notifies the communication terminal of the transmission source of information on the selected communication path.

In this way, the user of the source communication terminal can confirm the power with which the communication with the destination communication terminal is performed via any communication path. In addition, the number notification unit 53 notifies the information on the selected communication path to the source communication terminal only when the communication line selection unit 52 selects a communication path different from the communication path related to the connection request. May be. In this way, a notification is received when a communication route that is not intended by the user of the communication terminal of the transmission source is selected, so that the user can choose to perform the communication or the communication route can be It is also possible to perform corresponding communication. This also reduces the amount of system traffic because it is not necessary to provide notification in all cases. [0029] As in the case of fixed network exchange l2, the notified communication path information includes communication path identification information corresponding to the selected communication path (for example, a communication path via a cellular system, Information indicating that the communication path is via a fixed network) or the telephone number information of the communication terminal of the destination corresponding to the selected communication path (for example, an FMC compatible mobile telephone terminal is a telephone in the mobile network) And a telephone number corresponding to the selected route).

The mobile phone terminal 30 which is one of the communication terminals has a called party number receiving unit 54 and a called party number display unit 55.

[0031] The called party number display unit 55 receives the information of the selected communication path notified from the number notification unit 51 or the number notification unit 53 via the called party number receiving unit 54, and displays the received information. Informs the user by showing. Note that the method of notifying the communication path information is not limited to display, but may be notified by sound, light, vibration, or the like. In other words, the phone number may be read aloud, the communication line type LED may be turned on / off / blinking, or the ringing tone may be used.

Fixed telephone terminal 40, which is one of the communication terminals, has a recipient number receiving unit 56 and a recipient number display unit 57 that function in the same manner as mobile phone terminal 30.

A communication path setting method in the network system configured as described above will be described with reference to FIG.

[0034] In step 201, the FMC home adapter 11 determines whether or not the FMC-compatible mobile phone terminal 10 that is the communication terminal to be detected is detected in the area of the own device. The determination result is notified from the FMC home adapter 11 to the fixed network exchange 12.

[0035] When the determination result received by the fixed network switch 12 indicates that the communication terminal to be detected does not exist (step 201: NO), the fixed network shelf 12 determines that the transfer candidate MMS 22 Then, a transfer setting release signal is notified (step 202). By doing so, the MMS 22 can exclude the option power of the communication path through the fixed network that is known not to be connected as the transfer path when the communication terminal is not connected. As a result, useless signal exchange can be prevented in advance, and the amount of system traffic can be reduced. This notice is sent from the fixed exchange network 14 via the gateway 13. The mobile switching network 15 is entered and notified to the MMS 22. The same applies hereinafter.

In Step 203, the MMS 22 that has received the transfer setting cancellation signal cancels the transfer setting to the fixed network switch 12. That is, the communication path via the fixed network switch 12 is deleted from the communication circuit options.

[0037] In step 204, when the fixed network switch 12 receives a call to a fixed telephone number (that is, communication via the FMC residential adapter 11), it is transferred to the mobile telephone number (that is, the communication path via the MMS 22). Perform the transfer settings as follows. In this way, even if there is a connection request to the FMC-compatible mobile phone terminal 10 with the telephone number on the fixed network side, the fixed network exchange 12 will not be connected. Without selecting a route via the adapter 11, a communication route via the MMS 22 that may be connected can be selected.

[0038] On the other hand, when the determination result received by the fixed network switch 12 indicates that there is a communication terminal to be detected (step 201: YES), the fixed network exchange 12 is connected via the MMS 22. Cancel the transfer settings (step 205). In other words, the communication path via MMS22 is deleted from the communication path options. By doing so, it is possible to preferentially select the route via the FMC home adapter 11 when the possibility of connection is high.

[0039] In step 206, the fixed network exchange 12 notifies the MMS 22 to start setting the communication path via the own network as the transfer path. This notification is sent from the fixed switching network 14 to the mobile switching network 15 via the gateway 13 and notified to the MMS 22.

[0040] In step 207, the MMS 22 performs transfer setting so as to transfer to the fixed telephone number when an incoming call is made to the mobile telephone number.

Next, the operation of the network system when the destination communication terminal is the FMC compatible mobile phone terminal 10 will be described with reference to FIG.

[0042] In FIG. 3A, when the FMC compatible mobile phone terminal 10 is detected by the FMC home adapter 11, the mobile phone terminal 30 is moved from the mobile phone terminal 30 as the caller communication terminal. A flow in a case where a call is made to a mobile phone number on the network side is shown.

[0043] In step 301, the mobile phone terminal 30 makes a call to the mobile phone number of the FMC compatible mobile phone terminal 10 that is the destination. Then, by MMS33, mobile phone against MMS22 A connection request (incoming request) for the number is sent.

[0044] In step 302, the MMS 22 that has received the connection request analyzes whether the mobile phone number (corresponding to the communication path) related to the connection request is set to transfer, and the selected communication path is selected. A transfer request is sent to MMS 33 together with the fixed telephone number information of the transfer destination corresponding to the information.

[0045] The MMS 33 notifies the caller mobile phone terminal 30 of the transfer destination fixed phone number information, which is the actual destination phone number, via the RNC 32 and BTS 31, and the mobile phone terminal 30 notifies this notification. Receive the call and display the landline number on the terminal display (step 303).

[0046] The MMS 33 sends a connection request (incoming request) for the transfer destination fixed telephone number to the fixed network switch 12 via the gateway switch 13, and the fixed network switch 12 passes through the FMC in-home adapter 11 Call the FMC compatible mobile phone terminal 10 (step 304).

[0047] In step 305, the FMC compatible mobile phone terminal 10 answers the incoming call. In this way, the call is established (step 306).

[0048] FIG. 3B shows that when the FMC compatible mobile phone terminal 10 is not detected by the FMC home adapter 11, the fixed phone terminal 40 is used as the communication terminal of the transmission source and the fixed phone terminal 40 is connected to the fixed network side. The flow in the case of calling to a fixed telephone number is shown.

In Step 311, the fixed telephone terminal 40 makes a call to the fixed telephone number of the FMC compatible mobile telephone terminal 10 that is the destination. Then, a connection request (incoming request) for a fixed telephone number is transmitted to the fixed network switch 12 by the connected fixed network exchange 41.

[0050] In step 312, the fixed network switch 12 that has received the connection request analyzes whether the fixed telephone number (corresponding to the communication path) related to the connection request is set to transfer, and the selected communication path. A transfer request is transmitted to the fixed network shelf 41 together with the mobile phone number information corresponding to the information of

[0051] The fixed network switch 41 notifies the caller's fixed phone terminal 40 of the transfer destination's mobile phone number information, which is the actual destination phone number. The fixed phone terminal 40 receives this notification and receives the notification. The telephone number is displayed on the terminal display (step 313).

[0052] The fixed network switch 41 passes the mobile switch of the transfer destination to the MMS 22 via the gateway switch 13. A connection request (incoming call request) for the talk number is transmitted, and the MMS 22 calls the FMC compatible mobile phone terminal 10 as a mobile phone via the RNC or BTS (step 314).

In Step 315, the incoming call response is made to the FMC compatible mobile phone terminal 10. A call is thus established (step 316).

In FIG. 3C, when the FMC compatible mobile phone terminal 10 is not detected by the FMC home adapter 11, the fixed phone terminal 40 is used as the communication terminal of the transmission source, and the mobile phone side The flow in the case of calling to a mobile phone number is shown.

[0055] In step 321, the fixed telephone terminal 40 makes a call to the mobile phone number of the FMC compatible mobile phone terminal 10 that is the destination. Then, the connected MMS 33 transmits a connection request (incoming request) for the mobile phone number to the MMS 22.

[0056] In step 322, the MMS 22 that has received the connection request analyzes whether the fixed telephone number (corresponding to the communication path) related to the connection request has been set to transfer, and selects the communication path to be selected. The mobile phone number information corresponding to the information is notified to the fixed network switch 41. Here, FMC compatible mobile phone terminal 10 is not detected by FMC home adapter 11! Therefore, in the MMS 22, the communication path via the fixed network switch 12 and the FMC home adapter 11 is excluded from the selected communication path options. Therefore, MMS22 will select the communication path on the mobile network side, and a transfer request will also be sent.

[0057] The fixed network switch 41 notifies the source fixed telephone terminal 40, and the fixed telephone terminal 40 receives this notification and displays the mobile phone number on the terminal display (step 323).

[0058] The MMS 22 calls the FMC compatible mobile phone terminal 10 as a mobile phone via the RNC 21 or the BTS 20 (step 324).

[0059] In step 325, an incoming call response is made to the FMC compatible mobile phone terminal 10. This establishes the call (step 326).

[0060] In the OnePhone service, which is the main service form of the FMC service, the phone numbers used for incoming calls are integrated into one, so that the fixed phone number and the mobile phone number are the same as in this embodiment. Do not send to both. When this embodiment is applied to the OnePhone service, the call to the mobile phone number is made by the phone number of the OnePhone service. You can replace it with outgoing calls.

Further, in this embodiment, an IP telephone line has been added to simplify the explanation, but the same applies when an IP telephone line is used. It can be replaced with an IP phone line. When an IP phone line is used, a usage method in which a telephone number is not assigned can be considered, and a method of notifying the type of line used is more effective than a telephone number.

In this embodiment, for convenience of explanation, the signal line information for incoming / outgoing calls and the voice information of the call are shown on the same route, but different routes and different systems may be used.

[0063] In addition, as an additional function of the present embodiment, there is a function that allows the user to check the presence / absence of a service area (at home) in advance without calling until a certain time or a specific operation after the call, For protection, it may be possible to provide a function that is not notified by time of day based on the designation of the called party, or a function that notifies only when the specified caller ID.

[0064] In the above description, the processing of step 302 and step 303 may be performed in parallel, and there is no problem in the implementation of the present invention even if they are slightly different. The same applies to the processing in step 313 and step 314 and the processing in step 322 and step 324. Calls are not forwarded to reduce processing in the phone system! In this case, it is possible not to notify the destination telephone number. 実現 It is possible to realize that the process of step 322 and step 323 is not executed. At that time, as a device in the phone terminal, it may be possible to display the phone number sent on the phone terminal instead of the destination phone number that is not notified.

As described above, according to the present embodiment, the source communication terminal (mobile phone terminal 30, fixed) is connected to MMS22 (fixed network switch 12) that is arranged on the network and controls communication between communication terminals. (Telephone terminal 40) Communication line selection unit 52 (communication line selection unit 50) as a communication path selection means for selecting one communication path from among a plurality of communication paths to a destination communication terminal in response to a power connection request ) And a number notification unit 53 (number notification unit 51) as a route notification means for notifying the transmission source communication terminal of the information of the selected communication route.

In this way, even if a communication path different from the communication path related to the connection request is selected, the transmission source communication terminal can recognize this fact.

[0067] The number notification unit 53 (number notification unit 51) as a route notification unit is used as a communication route selection unit. Only when a communication path different from the communication path related to the connection request is selected by the communication line selection unit 52 (communication line selection unit 50), the information on the selected communication path is transmitted to the communication terminal of the transmission source. Notify

[0068] By doing this, it is possible to receive a notification when a communication path that is not intended by the user of the caller communication terminal is selected. This also eliminates the need for notification in all cases, thus reducing the amount of system traffic.

[0069] If the destination communication terminal related to the connection request is not detected by the terminal detection unit 58, the communication line selection unit 50 selects a communication path via the mobile network device (MMS22), and the number notification unit 51 Only when the communication path via the mobile network device (MMS22) is selected by the communication line selection unit 50, the information on the selected communication path is notified to the communication terminal of the transmission source.

[0071] The MMS 422, which is a mobile network device arranged in the mobile network, has a number selection unit 452 and a number notification unit 453 as communication line selection means.

[0072] Number selection unit 452 uses the mobile phone terminal 410 or the telephone service provider to operate the mobile phone terminal 410 among a plurality of telephone numbers assigned to the mobile phone terminal 410. It has a function to hold the telephone number that the person selects the desired telephone number. Number selection unit 452 selects one communication path from among a plurality of communication paths (in this case, telephone numbers) to the destination communication terminal. The number selection unit 452 selects in advance the telephone number desired by the user of the own device, and within the fixed network where the own device (MMS422) is arranged. In response to a request for connection of the communication terminal, the user selects the desired telephone number from among a plurality of telephone numbers to the destination communication terminal.

[0073] The number notification unit 453 has a function of notifying a fixed telephone network switch or MMS of a transmission source of a desired telephone number and a function of notifying a telephone terminal of the notified desired telephone number. Have. Number notification unit 453 notifies the communication terminal of the transmission source of information on the selected communication path. The number notification unit 453 displays information on the selected communication path (telephone number) only when a communication path (telephone number) different from the communication path (telephone number) related to the connection request is selected by the number selection unit 452. May be sent to the originating communication terminal.

A mobile phone terminal 430 that is one of communication terminals has a callee number receiving unit 454 and a callee number display unit 455 that perform the same functions as the mobile phone terminal 30. A fixed telephone terminal 440, which is one of the communication terminals, includes a called party number receiving unit 456 and a called party number display unit 457 that function in the same manner as the mobile phone terminal 40.

In Step 501, the mobile phone terminal 430 makes a call to the mobile phone number 2 of the mobile phone terminal 410 that is the destination. Then, the MMS 433 transmits a connection request (incoming request) for the mobile phone number 2 to the MMS 422.

[0078] The MMS 422 that has received the incoming call request is for the mobile phone number (the number that is selected in advance as the number desired by the user!) That is set for the transfer of the telephone number related to the connection request. Analyze if there is. If the number is different from the desired number, MMS 422 transmits the information of the desired number (here, mobile phone number 1) to MMS 433 (step 502).

[0079] In step 503, the mobile phone terminal 430 receives the mobile phone number 1 via RNC432, BTS431, and MMS433, and the mobile phone number 1 is sent to the terminal device. Display on play.

In Step 504, the MMS 422 calls the mobile phone terminal 4 10 using the transfer destination mobile phone number 1.

In step 505, the mobile phone terminal 410 responds to the incoming call. This establishes the call (step 506).

[0082] With the above operation, the mobile phone number desired by the callee is automatically notified to the caller, and the desired mobile phone number is sent to the caller terminal as the call history. The caller can easily make a call to the mobile phone number 1 from the next time.

[0083] By continuing the incoming call by this operation, it is possible to considerably reduce the number of callers to be sent to mobile phone number 2, and after several months to a year, contract for mobile phone number 2 It is possible to cancel and consolidate to one of mobile phone numbers 1. In addition, since the number of lines that can be connected at the same time can be limited to one without canceling the contract for mobile phone number 2, an additional contract service that adds mobile phone number 2 to the basic contract for mobile phone number 1 is added. As an example, a company that manages and operates this system can provide it to users at low cost.

[0084] As is obvious from the above description, the second embodiment has many parts in common with the first embodiment, and it is possible to display the destination telephone number related to the FMC service and the number portability. The display of the desired mobile phone number related to can be realized by sharing many parts. In particular, the communication terminal of the present invention that is the operation on the calling side operates in the same manner in the first embodiment and the second embodiment, so that it is effective to implement it simultaneously when mounted on the communication terminal. .

As described above, according to the second embodiment, the MMS 422 that is arranged on the network and controls communication between the communication terminals is connected to the source communication terminal (mobile phone terminal 430, fixed phone terminal 440). In response to the connection request, a number selection unit 452 serving as a communication path selection unit that selects one communication path from among a plurality of communication paths (in this embodiment, a mobile phone number) to the destination communication terminal; A number notification unit 453 serving as a route notification means for notifying information of the selected communication route to the communication terminal that is the transmission source. [0086] By doing this, if the mobile phone number that the user desires to use is selected in advance, even if the mobile phone number related to the connection request is different from the desired mobile phone number, Not only can it communicate, but it can also notify the desired mobile phone number to the originating communication terminal. As a result, it is possible to prompt the user of the communication terminal that is the sender to use the desired mobile phone number from the next time, and it is possible to aggregate a plurality of mobile phone numbers.

[0087] (Other embodiments)

In the second embodiment, the case where the transfer method is applied has been described. However, the non-transfer method can also be applied as described below.

FIG. 5B shows an operation when mobile phone number 1 is set as a desired phone number in MMS 422 and a call is sent to mobile phone number 2. In Figure 5B, the no-transfer method is applied.

[0089] In step 511, the mobile phone terminal 430 makes a call to the mobile phone number 2 of the mobile phone terminal 410 that is the destination. Then, a connection request (incoming request) for mobile phone number 2 is sent to MMS422.

[0090] Receiving the connection request, MMS 422 analyzes whether the telephone number related to the connection request is for mobile phone terminal 410 for which the desired telephone number is set by number selection unit 452. If set, MMS 422 transmits (notifies) information on the desired telephone number to MMS 433 (step 512). Here, since mobile phone number 1 is set as the desired phone number, information on mobile phone number 1 is transmitted to MMS433.

[0091] In step 513, the mobile phone terminal 430 that receives the mobile phone number 1 receives the mobile phone number 1 via the RNC 432 and the BTS 431, and displays the received mobile phone number 1 on the display of the terminal.

In step 514, the MMS 422 calls the mobile phone terminal 4 10 using the mobile phone number 2 that has been transmitted.

In Step 515, the FMC compatible mobile phone terminal 410 responds to the incoming call. A call is thus established (step 516). The same flow applies when making a call from landline terminal 440. Become one.
