The most deemed closest communication in life to the general public is a landline telephone using a public telephone network.
In addition to such landline telephones, home communication devices that can only be moved in residential areas of users began to appear in Korea since the late 1970s, and are commonly referred to as cordless phones.
This radiotelephone uses 46 / 49Mhz frequency band, indoor communication distance is generally 50m, channel interval is 25khz, and FM modulation method is used.In the early 1980s, fixed channel method was used. MCA (Multi Channel Access) method, which is called a request channel method, is commercially available.
In the 1990s, wireless phones in the 900 MHz band appeared in consideration of the improvement of call quality.
As described above, a cordless telephone that is made to be used only in a residential area by wirelessizing the handset of a home general telephone is called CT-1 (First Generation Cordless Phone).
CT-1 can only be used at home, so it cannot be used in public places. In order to improve this point, the first generation cordless phone (CT-2) system, called the outgoing cell phone, was first proposed in the UK in 1989. Has been adopted as a European standard and is currently being serviced in several countries.
In short, the CT-2 features a pedestrian wireless public telephone that can be used as a CT-1 at home and walks within a 200-meter radius used as a public telephone in public places.
The disadvantage of CT-2 is that there is no incoming call, no handover. The third generation cordless phone (CT-3) has emerged in order to compensate for these shortcomings.
CT-3 can be classified into private network and public network according to the purpose of use, and can be explained mainly from private exchange system (PBX).
Conventionally, private communication system is mainly used for communication system used for business in building, and wireless system is emerged as wireless communication system (Wireless PBX) which makes this system wireless and enables mobile communication in building. DECT can also be seen as a system.
The DECT (Digital European Cordless Telephone) system, a representative example of the CT-3 system, was adopted as a European standard in March 1992 by the European Telecommunications Standards Institute (ETSI).
The main characteristic of this system is that the wireless access method is TDMA method and uses 2Ghz band and the channel bandwidth is 1.73Mhz and has 12 time slots per channel.
By developing the CT-3 system to the public network level by supplementing system functions such as handover and roaming, low-tier PCS, a personal communication system evolved from wireless telephones, a system that realizes personal communication that enables communication with anyone, anytime, anywhere (Personal Communication Service) has emerged.
Low Tier Personal Communication Service (PCS) allows wireless and pedestrian and indoor services to be provided as a basis, such as DECT in Europe, Personal Hand-phone System (PHS) in Japan, and PACS in the United States. (Personal Access Communication Service).
On the other hand, there is a high tier Personal Communication Service (PCS) that is microcelled to provide vehicle-oriented services including pedestrians by developing analog cellular technology as a counterpart to the low tier Personal Communication Service (PCS).
Analog cellular, which is the foundation of High Tier Personal Communication Service (PCS), was introduced in October 1983 by AMPS (Advanced Mobile Phone Service) developed by Bell Lab, and introduced the cell concept in the 824 ~ 894Mhz band. The channel band is 30kHz and the modulation method FM.
Analog cellular systems have been used in Europe such as NMT (Nordic Mobile Telephone), TACS (TAC), and NTT.
However, as the number of mobile subscribers increases rapidly in the late 80s, the system has emerged as a way to improve the limitations of capacity and the deterioration of communication quality and various demands of services.
In order to improve capacity, communication quality and data service, which is a disadvantage of analog cellular, Korea developed narrowband CDMA method and started commercial service since early 1996. In the United States, IS-95 CDMA was standardized in July 1993. Both IS-54 TDMA schemes have been developed.
In addition, the GSM (Group Special Mobile) method, which used TDMA as a pan-European method in Europe, began earlier than others, and it is possible to interconnect with countries in Europe, and commercialization started in 1992.
And in Japan, in early 1993, PDC (Public Digital Communications) method using TDMA was commercialized.
However, such a digital cellular system can be regarded as having solved the call quality and a certain amount of capacity, but can not be regarded as a system that can be used by everyone in the public at low cost, that is, it is not suitable for providing a universal service.
Therefore, what has evolved to become a universal service for digital vehicle mobile phone systems can be called High Tier Personal Communication Service (PCS), which has the advantages of high speed mobility, simple network configuration, and the use of digital cellular technology.
High Tier Personal Communication Service (PCS) systems include Up-band IS-95 CDMA, which evolved from IS-95 CDMA, and DSC-1800 (Digital Communication System), which evolved from GSM.
Meanwhile, as described above, the development of a personal communication service (PCS) system can be divided into a high tier personal communication service (PCS) and a low tier personal communication service (PCS). It is progressing to accommodate the tier method, and the low tier method is also progressing to accommodate the high tier method and ultimately is being integrated into IMT-2000 (FPLMTS, Future Public Land Mobile Telecommunication System).
The communication network of IMT-2000 is a structure of interworking structure by integrating wired and wireless. A network capable of high speed data transmission (384kbps) from low speed data transmission (14.4kbps), which is a wireless environment, is constructed. Many experts predict that the activation of the Internet will become visible.
In recent years, various wired and wireless communication systems have been developed to integrate wired and wireless networks such as public telephone networks and mobile communication networks, which are already established as a preliminary stage of the IMT-2000, to enable wired and wireless integrated services.
In addition, a mobile terminal that supports multiple bands and multiple modes in the mobile terminal side (hereinafter, referred to as a composite wireless terminal because it provides a multi-band service and a multi-mode service in one mobile terminal) has been developed. There is a mobile terminal with dual band / dual mode which can provide both telephone and mobile communication functions.
Dual band / dual mode mobile terminal which provides both wireless phone function and mobile communication function is called dual band because it can support both frequency band used in wireless phone and frequency band used in mobile communication. It is called dual mode by providing all modes.
In addition, there are PCS / AMPS type mobile terminals as dual mode mobile terminals, and GSM900 / GSM1800 as dual band mobile terminals.
The multi-band and multi-mode mobile terminals can operate in one single band / single mode by manual operation of the user, and can also operate in dual band / dual mode by manual operation. Of course, it is possible to maintain the connection with the communication network that can be guaranteed more in case of automatically moving from one network to another network.
On the other hand, the recent development of wireless communication network-related technology has been made remarkable, and many technical standards have been proposed. Noteworthy technical standards include Bluetooth technology standard and wireless LAN field. Coupled closely, the development of multi-band and multi-mode mobile terminals has resulted.
However, the conventional method using a hybrid wireless terminal having multiple bands and multiple modes has a problem that the called party has to retry the call setup again when the incoming call fails in one network because the network and the network are separated. .
As a result, CDMA, GSM, and WCDMA, which are broadband in service areas, have a significant drop in services in shaded areas, underground, and in buildings, and still have to install a repeater for such a place.
In addition, communication systems serving small areas such as WLAN and Bluetooth can provide high-quality services at low cost, but as the service areas are not extensive and restricted in mobility, technology development for expansion of service area and securing mobility is inevitable. need.
In addition, when a user of a composite wireless terminal having multiple bands and multiple modes moves from a general public telephone network to a mobile communication network or from a mobile communication network to a public telephone network during transmission, there is a problem in that the call is disconnected because the handoff is not provided between the two networks.
Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to enable the registration of the location of the service user automatically using a composite wireless terminal providing multiple bands and multiple modes. The present invention provides a composite wireless service apparatus and a method using a wired / wireless communication system that attempts to automatically receive a call through another network when a call fails when a voice and data call is received.
Another object of the present invention is to provide a manganese handoff when moving a service area of a composite wireless terminal among voice and data call services of a composite wireless terminal so that a seamless voice and data service can be performed when a service user moves manganese during transmission. The present invention provides a composite wireless service apparatus using a wired and wireless communication system and a method thereof.

However, when the composite wireless terminal moves to the premises wireless network service area, the mobile switching center maintains the call path (step S120), and when the call ends (step S122), releases the call (step S124), and then the position for the composite wireless terminal. Is registered in the home position register (step S126).
In this case, when moving to the wireless network service area in the premises, the call path is maintained through the mobile communication network. Alternatively, the location registration may be allowed to switch the call so that the service is provided through the wireless network.
6 is a flowchart illustrating an outgoing call processing process of a complex wireless terminal located in a premises service area according to another exemplary embodiment of the present invention.
As shown in Fig. 6, when the wired / wireless composite gateway receives an outgoing signal from the composite wireless terminal via the mobile communication network (i.e., the called party is the mobile communication terminal) (step S210), via the mobile switching center. A call is set up with the called terminal (step S212).
Subsequently, it is determined whether the composite wireless terminal has moved to the mobile communication network service area (step S214). If the mobile station does not move to the mobile communication network service area, the call is terminated as the call ends (steps S216 and 218).
However, if the composite wireless terminal moves to the mobile communication network service area, the mobile switching center causes the wired / wireless composite gateway to disconnect the call after performing location registration for the composite wireless terminal (step S220), and the mobile communication network is the base station controller and the base station. The call is set using (step S222). Thereafter, the call is released when the call ends (steps S224, 226).
Herein, the case where the called party is a subscriber of the mobile communication network has been described, but the same can be implemented when the subscriber is a public telephone network subscriber.
Of course, in this case, the mobile switching center can set the call path by receiving the called party's telephone number from the wired / wireless hybrid gateway.
7 is a flowchart illustrating an incoming call processing procedure for a composite wireless terminal via a mobile communication network according to another embodiment of the present invention.
As shown in Fig. 7, when the mobile switching center receives an incoming call for the composite wireless terminal (step S310), the mobile switching station checks the position (step S312) and locates in the mobile communication network service area through the base station controller and the base station. Provide a mobile communication service (step S316). At this time, the mobile switching center notifies the called party by sending a busy message to the called party if the composite wireless terminal is busy.
Subsequently, it is monitored whether the composite wireless terminal moves to the premises wireless network service area (step S318), and the call is released when the call ends without moving (steps S328 and 330).
When the composite wireless terminal moves to the premises wireless network service area, in this case, it still maintains the call through the mobile communication network (step S320), and after the call ends (step S322), the call is released (step S324) and the position is changed. It registers (step S326).
On the other hand, when receiving an incoming call and confirming the location, and located in the wireless network service area of the premises, the extension number and the called number are transmitted by using an outgoing telephone number service as an example of the wired / wireless composite gateway (step S332), and the wired / wireless composite gateway makes a call. (Step S334). At this time, the mobile switching station notifies the busy party by transmitting a busy message to the called party when the complex wireless terminal is busy.
Subsequently, if it is determined whether the composite wireless terminal has moved to the mobile communication network service area (step S336), allowing the mobile station to set up a call by allowing location registration (step S338). It releases (step S342).
If the call is terminated, the call is released (steps S344 and 346).
8 is a flowchart illustrating an incoming call processing procedure for a composite wireless terminal via an on-premises wireless network according to another embodiment of the present invention.
As shown in Fig. 8, when the wired / wireless hybrid gateway receives an incoming call via the local exchange for the composite wireless terminal (step S410), it tries to receive the composite wireless terminal to determine whether it is absent (step S412). .
As a result of determination, the wired / wireless composite gateway checks the location information of the composite wireless terminal received from the mobile switching center or received in real time (step S414). As a result of the positioning of the composite wireless terminal, the composite wireless terminal provides the mobile communication network service. If it is located in the area, the call path is established via the mobile switching center, the base station controller, and the base station (step S416).
As a result of the determination, if the call is absent, the call is established by establishing a communication path with the composite wireless terminal using the wired / wireless composite gateway.
Here, it is implemented to reduce the load of the wired / wireless hybrid gateway by determining the location in the absence, but may be implemented to provide a wireless service according to the identified location by first determining the location when an incoming call to the hybrid wireless terminal is attempted.
Meanwhile, although the embodiment of the present invention has been described with reference to a network of a CDMA mobile communication network, the same may be applied to GSM and WCDMA.
In addition, although the wired / wireless composite gateway is configured to share the location information of the composite wireless terminal stored in the home location register of the mobile switching center, only the home location register of the mobile switching station manages the location information of the composite wireless terminal and accordingly only the mobile switching station It may be implemented to perform this call forwarding service.
In the above embodiment, the voice call service is described in the composite wireless service. Hereinafter, the data service will be briefly described with reference to FIG. 9.
FIG. 9 is a configuration diagram of a composite wireless service apparatus capable of data communication in a wired / wireless communication system according to another embodiment of the present invention, and description thereof will be omitted for the same components that overlap with the system shown in FIG. 1.
As shown in FIG. 9, in the composite wireless service apparatus for data service, a PDSN / FA (Packet Data Serving Node / Foreign Agent) 180 and a Home Agent (HA) 181 are provided in the apparatus shown in FIG. 1. Will be configured additionally.

In addition, in the case of a data service, when handing off a composite wireless terminal, the mobile terminal assigned the mobile IP is guaranteed mobility and is serviced through the same PDSN. If the terminal receives the data service through the intranet, it will not receive the data service in the premises when moving to the outside.
If the wireless terminal is out of the service area of the premises network while receiving data service in the premises, the
Accordingly, the
Meanwhile, IP allocation and data handoff functions using mobile IP are performed as follows.
All mobility agents periodically broadcast an Agent Advertisement message that extends a Router Advertisement message to inform their mobility support. The mobile node receiving the message can use the information in the message to determine if it is located in the home network or moved to a new external network.
Representative methods for determining the movement of a mobile node include Lazy Cell Switching (LCS) and Egg Cell Switching (ECS).
In the case of the LCS, if the agent advertisement message for the current network is not received for a certain period of time, the LCS determines that it has left the current network and registers a new location. On the other hand, in the case of ECS, if an agent advertisement message is received from an external agent in a new network instead of the current network, it is determined to move to a new network. Therefore, while the delay of the movement determination is faster than that of the LCS, the accuracy of the movement determination is not guaranteed, and there is a disadvantage in that the influence of the node's movement pattern is more affected than that of the LCS.
Recognizing that a mobile node has moved to an external network, a new COA can be obtained, which can be either a foreign agent care-of address (FA COA) obtained from an agent advertisement message or a temporary IP address obtained through DHCP. CCOA: Colocated Care-of Address. In the case of CCOA, since the tunnel end point is a mobile node, it is more effective to use FA COA than CCOA in wireless environment because additional header is transmitted through wireless channel, which makes packet overhead larger than FA COA.
10 shows a registration process between the mobile node and the HA that moved to the external network.
As shown in FIG. 10, the mobile node transmits a Registration Request message to the HA in order to establish mobility binding of the home address and the COA, and receives a Registration Reply message in response thereto. . This registration message includes the home address and COA of the mobile node, as well as information on the registration life time and mutual authentication between the HA and the mobile node.
In addition, binding information of mobile nodes managed by HA should be periodically updated by mobile nodes within a registration maintenance time to maintain mobility.
After the registration to the HA is completed, packets destined for the mobile node are tunneled to the COA by the HA that performs proxy ARP in the home network and delivered to the mobile node located in the external network. The packet sent by the mobile node is sent to the other node through normal IP routing and does not necessarily need to go through the FA.
11 illustrates a packet forwarding process from a counterpart node to a mobile node located in an external network.
As shown in FIG. 11, when HA performs tunneling to deliver packets to a mobile node's COA, IP-in-IP encapsulation, minimal encapsulation, Generic Record Encapsulation (GRE) encapsulation, and the like. Encapsulation methods are used. Packets delivered to the tunnel destination through tunneling are decapsulated and delivered to the mobile node. If the destination of the tunnel is FA, it is de-encapsulated by FA and then delivered to the mobile node through normal IP forwarding process. If the destination of the tunnel is mobile node, the packet transmitted through the tunnel is de-encapsulated by mobile node to higher layer. Delivered. 12 is a diagram illustrating an IP-in-IP encapsulation process for an IP packet.

Meanwhile, when an incoming call is received from the PSTN network / data network to the AP, the incoming call processing process will be described.
First, when an incoming call transmitted from a PSTN line or a data network is received by the AP, the AP may support a narrowband and a landline telephone (SLT (Single line telephone) using a PSTN Line or a VoIP phone using a data line) connected to the AP. Call all mode wireless terminals so that all terminals perform concurrent ringing operations on incoming calls.
When one of the wired telephones or the dual-mode wireless terminals (one-phones) connected to the AP internal network responds, the response signal of the corresponding terminal is transmitted to the PSTN or data network. At this time, the AP terminates the ringing operation by removing the call of the other terminals except the answered terminal, and performs a call service connection between the called terminal and the calling terminal.
In addition, the AP or exchange that supports the narrowband wireless network service provides a call designation function for Caller ID (CID), and when an incoming call is requested from a CO line, an initial incoming call is made only to the one-phone terminal found by checking the provisional CID to Onephone DB. After doing this, if there is no response for a certain time, another terminal can service the incoming call.
Let us look at the process of performing a call service to a specific terminal using the CID.
First, a specific composite wireless terminal (hereinafter referred to as a one-phone terminal) for a receiving CID is designated in the AP or database in the private exchange.
After an incoming call is received from the PSTN / data network after a specific one-phone terminal called for the CID is received, the AP or private exchange analyzes whether the received call includes a CID, and if the CID is included, the AP or private exchange. The destination phone terminal specified in the database is searched.
If there is a one-phone terminal corresponding to the CID for the incoming call, the corresponding one-phone terminal is called.
When there is a call response from the called one-phone terminal, the AP or the private exchange connects a call between mutual terminals to provide a call service.
That is, when an incoming call is received from the PSTN / data network, the AP or private exchange analyzes whether the received call includes a CID.
As a result of the analysis, when the received call includes a CID, the terminal determines whether there is a call designated terminal, that is, a call designated CID, by searching for the called terminal designated in the database of the AP or the private exchange.
As a result of the determination, when the incoming designated one-phone terminal exists, it is determined whether the corresponding one-phone terminal is located in the one-phone service area, and if the corresponding one-phone terminal is located in the one-phone service area, an incoming call service is requested to the incoming-designated one-phone terminal.
When a call service request is received, if there is a call service response from the designated one-phone terminal, a call service is performed by connecting a call between terminals.
On the other hand, if there is no call-designated one-phone terminal in the database in the AP or private exchange, if the call-designated one-phone terminal is not located in the one-phone service area and if there is no call service response from the call-designated one-phone terminal, the call is sent to the AP. Incoming call service is required for all connected terminals. In other words, if all terminals connected to the AP call and there is a service response from one of the terminals, the call is made with the corresponding terminal.
In addition, if there is no response from all terminals connected to the AP for the call from the trunk line (PSTN or data service network) through the wire, the CID received by the designated call designated one-phone terminal is analyzed and the information on the incoming call is transmitted by SMS message. Transfer or perform a call transfer service to the designated terminal, let's explain this process.
First, the SMS service is assigned to a specific one-phone terminal for the received CID in the database in the AP or private exchange. That is, when a call service is requested to a specific terminal while a call service is designated to a specific terminal for a received CID, an SMS service for transmitting an SMS message to the specific terminal is designated when there is no call service response of the terminal.
When an incoming call is received through the PSTN or the data network while the SMS service is designated to a specific terminal, the AP or the private exchange determines whether the received call includes a CID.
As a result of the determination, when the CID is included in the incoming call, it is searched from the database to determine whether there is a call-designated one-phone terminal corresponding to the CID.
If the incoming designated one-phone terminal exists, the incoming call is requested to the corresponding one-phone terminal.
If there is no response from the designated terminal according to the incoming call request, all terminals connected to the AP are called.
As a result of the call, when there is no response to the call from all the terminals, the SMS message including the CID is transmitted to the SMS designated one-phone terminal, and the SMS message including the CID is transmitted to the counterpart terminal through the PSTN or the data network.
On the other hand, after transmitting the SMS, it is possible to perform a call transfer service to the designated terminal, let's look at this process.
A call transfer service is assigned to a specific one phone for a receiving CID in a database in an AP or a private exchange.
When an incoming call is received through a PSTN or a data network with a call switching service assigned to a specific terminal, the AP or private exchange determines whether the received call includes a CID.
As a result of the determination, when the CID is included in the incoming call, it is searched from the database to determine whether there is a call-designated one-phone terminal corresponding to the CID.
If the incoming designated one-phone terminal exists, the incoming call is requested to the corresponding one-phone terminal.
If there is no response from the designated terminal according to the incoming call request, all terminals connected to the AP are called.
As a result of the call, when there is no response to the call from all terminals, the SMS message including the CID is transmitted to the SMS designated one-phone terminal, and the SMS message including the CID is transmitted to the counterpart terminal through the PSTN or the data network.
In addition, the AP or private exchange requires the call exchange service including the designated specific one-phone terminal information to the public exchange. Therefore, the public exchange switches a call to a specific terminal for a call transfer service specified in the database of the AP or private exchange and performs a call forwarding request to the switched terminal.
Hereinafter, a processing method for a call received from an external network (GSM, CDMA ,,,) during a call (both outgoing and incoming) for a PSTN or a wired VoIP call through a one-phone terminal will be described.
First, when there is an incoming call service request through the PSTN or data network, the AP or private exchange requests the incoming call to the one-phone terminal, and the one-phone terminal notifies the user that the incoming call has been received.
Accordingly, the user hooks off the one-phone terminal, and the one-phone terminal transmits a response signal for the incoming call to the AP according to the user's hook-off.
The AP transmits the incoming call service response signal to the PSTN or the data network (public exchange) according to the incoming response signal transmitted from the one-phone terminal.
Therefore, the call for the incoming call with the one-phone terminal is made through the PSTN or data network.
As such, when there is an incoming call service request to the one-phone terminal through the broadband network while the terminal is talking through the PSTN / data network, the one-phone terminal displays the broadband network call service request to the user as a beep sound or a message. Inform the incoming call information so that the incoming call can be selected from the broadband network.
If the user selects an arbitrary key to receive an incoming call from the broadband network, that is, responds to an incoming call from the broadband network, the one-phone terminal transfers the previous call to the AP, that is, through the PSTN or the data network. Requires a hold of an ongoing call.
Accordingly, the AP holds the previous call according to the hold signal for the previous call transmitted from the one-phone terminal, and notifies the PSTN or the data network of the hold for the previous call.
In addition, the one-phone terminal transmits a response signal to the incoming call transmitted from the broadband network, and performs a call with the opposite terminal through the broadband network.
As a result, when an incoming call from the external network is generated, the terminal itself notifies the user of the incoming call generation through a beep or a message.
In addition, when the user receives the incoming call generation message, the user can answer the call from the external network together with the suspension of the existing call. At this time, disconnecting or withholding an existing call (call through a wired line) by the terminal user may give a user a choice. That is, it may be a choice or fixed matter on the terminal use.
Alternatively, there may be a specific key (button) for removing an existing call and serving a call from an external wireless network, or a specific key (button) for ignoring service for a new call.
Next, referring to FIG. 17, a description will be given of a ming handoff process when moving a coverage area of a one-phone terminal (complex wireless terminal).
FIG. 17 is a diagram illustrating a signal flow for a handoff process of a hybrid wireless terminal in the hybrid wireless service device shown in FIG. 14.
First, as shown in FIG. 17, when the

On the other hand, after the composite wireless terminal moves from the private wireless network to the mobile network, it moves back to another service area of the private wireless network, that is, moves from the service area A of the private wireless network to the mobile network, and then moves back to the private wireless network service area B. In this case, since the IP-
Let's explain this handoff process in more detail.
If the one-phone terminal moves between service areas, for example, look at the call service operation for the case of moving from a narrow band to a broadband service area.
Determination of a case out of narrowband coverage may include a case where a radio signal strength indication (RSSI) level of a pilot or sync channel of a narrowband service is lowered or a data error rate is increased. An appropriate threshold value may be designated for each service coverage to serve as a criterion for escaping from the narrowband service area.
For example, an area having high RSSI values so as not to scan an area where the one-phone terminal can be located, an area for scanning the RSSI level of the terminal, and one-phone terminal starting to leave the narrow band Can be divided into That is, when the RSSI value is greater than or equal to the first reference value, it is determined that the original phone exists in the corresponding area because the pilot signal is high. If the RSSI value is less than or equal to the second reference value, the pilot signal cannot be detected. Since the rate value is very high, the one-phone terminal determines that it is out of the area. In addition, in the case of the RSSI value between the first reference value and the second reference value, it is determined that the one-phone terminal is out of the corresponding area and continuously performs the scanning operation of the one-phone terminal to check whether the coverage is out of coverage.
When the coverage of the one-phone terminal is a voice call, if the current call of the one-phone terminal is a voice call, the coverage deviation (movement) is notified by a voice signal (voice message, beep, melody ..), and the data call (if receiving data service). The message is displayed on the liquid crystal display (LCD) of the one-phone terminal by using a message, a pictogram, etc., to notify the user of the out-of-coverage situation on the LCD screen of the one-phone terminal. Of course, integrated notification methods can be used for each voice call and data call.
Let's take a look at the mode switching operation when moving the coverage of the one-phone terminal.
When moving from the external network to the AP in the narrowband service area, the AP performs the automatic mode switching of the terminal by searching through the periodic signal transmission to the one-phone terminal, or the user notifies the one-phone terminal to use the mode switching (narrowband service). Or broadband service).
When the AP moves to an external network (broadband network), the network operates in an external network access mode when no signal from the AP is received. In this case, an operation for periodically searching for the presence of a signal from the AP is performed.
In this case, the determination on the case where the one-phone terminal moves to the external network is a case where the signal or data error rate is increased as the signal strength of the AP of the narrowband network decreases or decreases as described above. Depending on the one-phone terminal and the AP can be obtained. If the one-phone terminal deviates from the threshold values of the RSSI and the error rate for the predetermined service area, it may be determined that the one-phone terminal is out of the narrow band service area. At this threshold value, data received from the AP is determined to be data that cannot be used normally.
The scanning cycle of the one-phone terminal should be made to move between service networks without the user's knowledge, and should satisfy the method of minimizing the power consumption of the terminal.
Hereinafter, the scanning method of the terminal when the coverage movement of the one-phone terminal will be described.
First, an active scanning duration of at least one AP has a long paging interval time interval of the AP.
According to the narrowband service protocol, the AP may respond only when there is a request of the terminal without paging, which does not affect the active scanning duration of the terminal and must wait for the response time of the maximum AP.
In addition, when the mobile phone is determined to move from the narrow band to the public band network, the mobile station determines the RSSI and the signal / data frame error rate. If the mobile phone is determined to move, the scanning period is shortened. In order to reduce the consumption, the scanning period is extended. That is, the idle time period is lengthened.
On the contrary, when the mobile phone is moved from the broadband network to the narrow band, the shift to the narrow band is not known. Therefore, scanning is performed at a period performed in the broadband and at least once AP scanning is performed to change the scanning period to move to the narrow band. Try to judge quickly.
On the other hand, when moving from a broadband network (external network) to a narrow band (AP), when the switch to the AP internal network is required, the AP wired data network notifies the use of the internal network to the one-phone management server of the external network or the internal network. Before use, it can notify the use of the internal network to the one phone management server of the external network through the external network.
In addition, when the AP moves to the external network, the AP does not detect the original phone and notifies the original phone management server of the original phone to the external network, or the original phone moved to the external network directly to the external network one-phone management server through the external network. Terminal movement can be notified.
Hereinafter, a method for performing data service in a narrowband service network using a one-phone terminal will be described.
First, a method of registering an initial one-phone terminal in a narrowband service network will be described.
First, the narrowband service AP is set to the registerable mode.
Subsequently, the one-phone terminal requests the user to enter a registration system ID or input information such as a user ID or a password.
When various information for registering the one-phone terminal is input from the user, the one-phone terminal transmits the input information to the AP, and the AP performs the narrowband network registration procedure according to the various information transmitted from the one-phone terminal.
The AP stores information about the registered one-phone terminal and sets the narrowband service AP to the deregistration mode.
Meanwhile, a method of using a wired data network after registering a one-phone terminal in a narrowband network through the above process will be described.
It is a serviceable method for an AP or private exchange supporting one-phone terminal service having a line capable of data service in addition to the PSTN interface.
First, every one-phone terminal may have a temporary IP or a fixed IP through an IP allocation procedure to use the data service if possible.
In the process of acquiring these IPs, authentication of the one-phone terminal can be performed. The method mainly used for authentication is to exchange user IDs and passwords using PPP (point-to-point protocol) (PAP, CHAP). Authentication flow) By performing authentication for a terminal or a user, a data session can be opened between an original phone and a wired data service network, and an account_start can be performed for the data session.
Otherwise, a separate authentication protocol may be used after IP allocation through a dynamic host configuration protocol (DHCP). In this case, encryption and authentication may be performed at the layer 3 level. At this time, the encryption used is 802.1x.
On the other hand, one-phone users can be connected to a wired data service network by using an independent hot key in the one-phone or using a menu key and an item key on a sub-menu for data service. have.
It is connected to a wired content server (for example, an application server) through a connected wired network. In this case, a content server can provide one-phone games, ringing sounds, and so on. By connecting to a server, one-phone users can provide specialized home networking services (eg, home view, home appliance control services, etc.).
On the other hand, in the accompanying Figures 13 to 17 described the case of installing the HLR in the mobile network and the private wireless network, respectively, but configures only one HLR to register the subscriber information and location information of the composite wireless terminal private radio to one HLR By storing and registering the location information of the network and the mobile network together, when the voice and data call service requests from the complex wireless terminal, the incoming call is switched to the corresponding network according to the location information of the corresponding terminal registered in the HLR. This embodiment is to enable the voice and data services to the true one-phone, that is, the terminal where the private wireless network and mobile network is located with one terminal number.
In other words, when the incoming request signal is received from the composite wireless terminal, by obtaining the position information of the terminal from the HLR and transfers the call to a network corresponding to the position information of the terminal, by using one terminal number private radio Voice and data services of networks and mobile networks are possible. Here, the location of the HLR may be installed in a private wireless network or may be installed in a mobile network.
The composite wireless service apparatus and the method using the wired / wireless communication system according to the present invention as described above enable the incoming call through the other network when the incoming call fails in one network, and the manganese to the composite wireless terminal. By providing a handoff, there is an effect of enabling a seamless call when the service user moves between manganese while originating.
In addition, the outgoing telephone number and extension number can be easily transmitted from the mobile switching center to the wired / wireless composite gateway by using the outgoing call indication function and provide handoff for multiple bands and multiple modes of the composite wireless terminal. By guaranteeing, there is an effect that can increase the usability of the composite wireless terminal.
In addition, by automatically providing a service through the on-premises wireless network for the composite wireless terminal, the user can reduce the communication fee, and provides the network handoff for the composite wireless terminal to minimize the disadvantages of the composite wireless terminal As a composite, there is an effect of creating a demand for a composite wireless terminal.
