Abstract

PURPOSE: A method for controlling a data service in a mobile exchange is provided to configure a wireless data service IWF(Inter Working Function) as a gadget of the mobile exchange, and to make the mobile exchange control the IWF. CONSTITUTION: If an idle MS(Mobile Station)(10) requests asynchronous data or a fax service, an MX(Mobile EXchange)(40) checks whether a calling subscriber is capable of calling and checks a called subscriber number. If the number is located in a local station, the MX(40) performs a paging and checks service options of the calling and a called subscriber. If the two subscribers request the asynchronous data or the fax service, the MX(40) starts a data service local call processing. If the called subscriber is registered in other exchange, the MX(40) occupies an outgoing trunk. If the service option of the calling subscriber requests the asynchronous data or the fax service, the MX(40) starts a data service outgoing call. The MX(40) occupies a wireless data communication IWF(Inter Working Function)(100) to connect a speech path, and transmits a response of a called control station to the IWF(100) and a calling control station, then starts a data service billing. If the MX(40) receives a response from a called exchange, the MX(40) transmits the response to the IWF(100) and the calling control station, then starts a data service billing. If a hand off is generated during a busy state, the MX(40) changes the speech path. If an additional service is requested, the MX(40) ignores the request. If a subscriber cuts off the speech path, the MX(40) performs a data service cancellation processing.

Description

Data Service Control Method in Mobile Switching

The present invention relates to a data service control method in a mobile switching center in a code division multiple access (CDMA) mobile communication network.

In the existing analytics network, data was exchanged using time slots that are not used by each channel in a voice call. In the digital network, a protocol is complicated by developing an IWF as a large-scale system and processing all data services required by the operator network in one place. Since it must be handled through a wireless data communication interworking device (IWF), which is located at a long distance, it is connected to the long data path from the exchange where the calling and receiving subscribers are located to the wireless data communication interworking device (IWF), which wastes network resources and increases performance. Even had a bad effect.

Accordingly, in the present invention, the wireless data communication interworking device (IWF), which is small in size and easy to develop, is used as an accessory device of the exchange, so that data service can be provided without adding any hardware device to the voice mobile exchange. The shorter communication path between the exchange and the wireless data communication interworking device (IWF) reduces the waste of network resources.The mobile communication exchange is occupied by the outgoing line when handling outgoing calls, and when the local call is handled, the BCS After receiving the paging response, the service option of the originating and receiving subscriber is examined to start the data service.The existing voice call control process is terminated, and the data service call control process and the wireless data communication interworking device (IWF) matching process are driven. Thereby independently providing data services without impacting existing voice calls It is an object of the present invention to provide a data service control method in a mobile switching center that does not need to develop complicated protocol processing for interworking with an IWF.

According to the present invention for achieving the above object, if the mobile station in the dormant state registered in the location area controlled by the mobile exchange requires asynchronous data or fax service, it checks whether the originating subscriber can make a call at the mobile exchange, If the user has registered his location in the home country, he or she will be paging. If the paging response is received, the service options of the calling and destination subscribers will be examined. If both subscribers request asynchronous data or fax service, the data service will be processed. A first step of occupying the outgoing line if the subscriber is registered with another operator's network or another exchange, and investigating the service option of the calling subscriber to start the data service outgoing call in case of asynchronous data or fax service request; Wireless data communication interworking device after performing step A second step of occupying the matching relay line, connecting the internal communication path of the switch, receiving an incoming response from the incoming control station, and transmitting the incoming response to the wireless data communication interworking device and the originating control station and initiating data service charging; After performing the first step, occupy the matching data line of the wireless data communication interlocking device, connect the internal communication path of the exchange, and when the incoming response is received from the incoming exchange, it is transmitted to the wireless data communication interworking device and the originating control station and data charging is started. After performing the third step and the second step or the third step, if the handoff occurs in the busy state, change the call path, ignore the request for additional service, and if the subscriber disconnects, perform data service release processing. It is characterized by comprising a fourth step.

The present invention provides a data service control method in a mobile communication network including a mobile terminal, a base station and a control station, a mobile switching center, a subscriber home location register, and a wireless data service interworking device. If a subscriber requests asynchronous data service or fax service, the mobile exchange analyzes the called number, and if the subscriber is registered with another operator's network or another mobile exchange, the subscriber occupies the relay line, and then investigates the outgoing subscriber service option. Initiate outgoing call processing, and if the called party is a subscriber registered with the same mobile exchange, the incoming and outgoing subscriber service option is examined after receiving the paging response, and both subscribers handle the data service local call when they are asynchronous data or fax service options. Start The.

The data service is a service in which a mobile subscriber uses a personal computer or facsimile connected to a mobile station terminal to perform end-to-end asynchronous data communication or fax transmission and reception with other subscribers. Since the data received from the subscriber is all digital, it can't be directly linked with the analog network like the existing public telephone network, so it converts the digital information into the analog information in the mobile network, performs the reverse conversion, and performs the speed matching function. Although the data communication interworking device (IWF) has been developed, since the wireless data communication interworking device is not involved in call control, it is determined whether to perform data service according to the service option received from the subscriber at the mobile switching center, and the mobile data communication interworking device with the originating mobile station. And wireless day Minimize development cost and effort to existing voice mobile switch by connecting communication path between communication interworking device and destination mobile station / receiving subscriber of other network, and sending control signal to wireless data communication interworking device at appropriate time to process data service. It is an object of the present invention to provide a data service to mobile subscribers.

In more detail, the MS 10 is a portable or in-vehicle subscriber terminal.

The BTS 20 performs radio matching with the MS 10 according to the instruction of the BSC 30.

The BSC 30 handles routing of information, various call processing, and handoff between the BTS 20 and the MX 40.

The HLR 90 stores various types of information on subscribers subscribed to the service provider and manages operations such as registration / cancellation.

ASS_M 50 is a mobile subscriber call control process 51 for controlling a mobile subscriber call in conjunction with a BSC 30 and an HLR 90, and a mobile subscriber call control process when the subscriber's service option is asynchronous data or fax service option. Data service call control processing 52 for processing data services on behalf of the above, handover control processing 53 for controlling hard handover between the BSC 30 or between the MX 40, and Time Switch; T-SW) to control the time division switch control process 54 for connecting / cutting the communication path between the BSC 30 and the space switch (S-SW) in the INS 70. Perform.

ASS-T (60) is connected to the relay line call control process 61 to control the outgoing and incoming call processing with other exchanges, routing processing to find a relay line that can be used in its own route (62), IWF (100) The specific ASS_T includes time division switch control processing (64) functions that perform functions such as IWF trunk line routing, trunk line information management, IWF matching processing 63 for call control, and time division switch control processing 54 in ASS_M 60. Perform.

And a paging process 73 for managing call status, a space division switch for connecting / disconnecting call paths between ASS subsystems, and performing a space switch control process 74 having a network synchronizer.

The CCS 80 is comprised of a Location Registration Subsystem (hereinafter referred to as LRS) 81 and an Administration and Maintenance Subsystem (hereinafter referred to as AMS) 82.

The LRS 81 performs a visitor location register function and performs registration with the HLR 90.

The AMS 82 performs system-wide maintenance, testing and measurement, and statistical processing, controls auxiliary storage, and is responsible for various input / output functions with the operator.

The IWF 100 is an accessory device of the MX 40 and performs a data rate matching function, a fax protocol processing, and a modem function by matching the MX with a T1 / E1 relay line.

2 (a) to 2 (c) are flow charts of data service initiation processing in a mobile switching center according to the present invention.

In FIG. 2 (a), the MS 10 registered in the location area of the MX 40 in the dormant state makes an asynchronous data service or fax service request using a PC or a fax connected to the terminal. The mobile subscriber call control process 51 in the ASS_M 50 of the MX 40 that receives the subscriber origination request via the BTS 20 and the BSC 30 (201) receives the originating subscriber number and the called subscriber received from the originating subscriber. Information such as number, outgoing subscriber service option, etc. is stored (202). An outgoing subscriber busy registers with the paging process 73 in the INS 70 (203). Outgoing subscriber information stored in the LRS 81 is analyzed (204). If the calling subscriber is unable to make a call because the call subscriber has registered a call blocking supplementary service or the call is stopped due to the cause of late payment, etc. (205), an abnormal release process is performed to connect a calling tone indicating that the call connection has failed (206). .

When the originating mobile subscriber cuts the call and receives an outgoing subscriber release notification from the BSC 30 (207), when the incoming mobile subscriber hears the ringing tone indicating that the call connection has failed (207), the ringing tone that was heard to the subscriber is cut off (208), and released to the BSC. After the notification of the acknowledgment (209), the subscriber status information registered in the paging process in a busy state in step 203 is registered in the idle state again (210), and the service is terminated in the idle state.

If the call is possible in step 205, the calling subscriber authentication is requested to the HLR 90 (211), if the authentication result is received (212), the result is examined (213) and if the authentication fails, the step 206 After the abnormal release processing is performed, if authentication is successful, the station number of the called subscriber received from the originating MS 10 is analyzed by the number analysis processing 71 in the INS 70 (214), and the called subscriber is the calling subscriber. If the subscriber is not the same network as the other network (215), outgoing processing after step 239 of FIG. 2 (c) is performed.

If the called subscriber is a subscriber of the same network as the calling subscriber in step 215, the routing information of the called subscriber is requested to the HLR 90 (216), and when receiving the routing information (217), the information is analyzed ( 218) If the called party is registered in another station, the outgoing process is performed after step 239 in FIG. 2 (c). If the called party is registered in the home station, the process proceeds to step 220 in FIG. 2 (b). The LRS 81 analyzes the information of the called subscriber.

At this time, if the incoming subscriber cannot register because the incoming call is registered or the call is suspended due to the late payment fee (221), the abnormal release processing after the step 206 of FIG. 2 (a) is performed. If this is possible, the paging process 73 in the INS 70 analyzes the paging information of the called party (222), and if the called party is already busy by examining the call state of the stored called party (223), the step 206 Subsequent abnormal release processing is performed.

In addition, when the called subscriber is idle, the called subscriber makes a paging request to the BSC 30 controlling the location registered area (224), and the calling subscriber hears a beeping signal indicating that the calling subscriber is being paging (225).

Receiving a paging response from the BSC 30 (226), cutting off the paging tone heard from the calling subscriber (227), requesting the incoming subscriber authentication to the HLR 90 (228) and receiving the authentication result (229) as a result If the authentication is failed (230) and the authentication fails, the abnormal release processing after the step 206 of FIG. 2 (a) is performed. If the authentication is successful, the call state of the called subscriber is registered in the call to the paging process 73. In operation 231, the calling terminal service option received in the subscriber origination request 201 and the called terminal service option received in the paging response 226 are analyzed (232).

If both originating and terminating are data service options requiring asynchronous data or fax services (233), performing data service local call processing (234); if both originating and terminating are general voice service options (235), normal mobile subscriber voice Local call processing is performed (236).

If the incoming / outgoing service option is wrong, the call connection is not possible, so the destination BSC 30 sends a connection rejection notification (237) to perform the release processing, and the paging process 73 puts the called party call state into the dormant state. It registers 238, and performs abnormal processing after step 206 of FIG. 2 (a).

In addition, in the case where the called subscriber is a subscriber belonging to another network in step 215 of FIG. 2 (a) or the called subscriber is a subscriber whose location is registered in another exchange in step 219, the step (c) of FIG. 239), the outgoing process begins, and the routing process (72 or 72 if the route within the ASS_T is congested) is performed to find the route connected to the other country (239), and checks whether there is a valid outgoing line in the route. (240), if there is no idle outgoing line, the abnormal release processing after step 206 of FIG. 2 (a) is performed, and if there is an idle outgoing line, the outgoing line is occupied (241). When the outgoing line is occupied (242), the called party number is sent to the called station (243). Then, the originating terminal service option received at the subscriber origination request 201 is analyzed (244) and the data service outgoing call processing is performed (246) when the data service option requires asynchronous data or fax service (245). If outgoing is not a data service option, normal voice outgoing call processing is performed (247).

3 (a) and 3 (b) are a flow diagram of a data service local call processing according to the present invention.

In step 234 of FIG. 2 (b), when the service options of the originating and receiving subscribers are examined, when both subscribers have asynchronous data or fax service options, the data service local call processing is started. Perform a data service local call initiation process that moves from the mobile subscriber call control process 51 to the data service call control process 52 (301), and the specific ASS_T (60) connected with the IWF (100) which is a wireless data communication interworking device; The IWF matching process 63 is also started (302).

IWF is largely divided into devices that perform speed matching and modem functions, and each is connected to a T1 / E1 relay line.For data service between mobile subscribers, the IWF is connected to the speed matching device within the IWF through a call line connected to the mobile subscriber. And the call path must be configured to connect back to the relay line connected to the MX through the modem device, so that the entire call path is in the outgoing ASS_M (50) of the originating MS (10) -BT (20) -BSC (30) -MX (40). Time Division Switch-IWF in Time Division Switch-INS 70 Connected with Time Division Switch-IWF in ASS-T 60 Connected to Speed Matching Device-IWF 100 in Modem-Mode Device-IWF in 100 Time Division Switch in ASS-T 60-Modem Device in Speed IWF-Speed Matching Device-Time Division Switch in ASS-T 60 in Connection with IWF-Space Division Switch in INS 70-Time Division Switch in Incoming ASS_M 50- BSC 30-BTS 20-MS 10 should be connected The.

Therefore, the IWF matching process performs data service routing processing differently depending on the type of call. In the case of a data service local call, two outgoing lines connected to the available IWF speed matching processing device to be connected to the calling subscriber line and the called subscriber call line in the corresponding route are included. If there is no idle outgoing line (304), the incoming BSC 30 sends a connection rejection notification 305 to disconnect the call, and then the paging control process 73 receives the call state of the called party. Is registered as idle (306) and the abnormal release processing after step 206 of Fig. 2A is performed.

If there are two idle IWF outgoing lines in step 304, the outgoing line is occupied (307). At this time, the IWF 100 detects the occupancy of the incoming line and knows the data service call processing request. It secures its own internal modem for use and occupies two outgoing lines connected to the modem device 102.

If two IWF incoming lines are occupied (308), the IWF matching process uses the spatial switch control processing 74 in the INS 70 and the time division switch control processing (54, 64) of the originating ASS_M and IWF matching ASS_T. The call route between the incoming and outgoing IWF outgoing line (309), and using the space switch control process (74) and the time division switch control process (54, 64) of the incoming ASS_M and IWF matched ASS_T. And connect the communication path between the IWF incoming line using the time division switch control process 64 of the IWF matching ASS_T (311).

In the mobile communication network, since the MX 40 starts handover processing after the call path is connected, when the handover occurs due to the movement of the originating and receiving subscribers, the MX 40 stores the connection indication information as the call so as to be able to handle it (312). A call acknowledgment is notified to the called BSC 30 (313) so that the called subscriber connects the call signal.

Upon receiving an alert notification from the destination BSC 30 (314), it forwards it to the originating BSC 30 (315), which initiates a protocol for data service between the originating terminal and the IWF modem.

When the called party listening to the call signal responds and receives a response notification from the called BSC 30 (316), two IWF incoming lines send a response signal (317) to process the data from the called terminal to the IWF 100. If the IWF sends out a response signal and detects it in the IWF outgoing line (318), it notifies the originating BSC 30 of the response (319), and receives the acknowledgment notification from the originating BSC (320). Beginning service charging (321), a data service call is in progress.

4 is a data service outgoing call processing flow chart according to the present invention.

In step 246 of FIG. 2, when the service option of the calling subscriber is examined and the data service outgoing call processing is started due to the asynchronous data or fax service option, the call control of the calling subscriber is transferred to the mobile subscriber call control process (51). Performs data service outgoing call initiation processing to be transferred to data service call control processing 52 (401), and performs IWF matching processing (63) in a specific ASS_T (60) connected with IWF 100, which is a wireless data communication interworking device. Start 402. Time division switch-INS 70 in the originating ASS_M 50 of the originating MS 10 -BTS 20 -BSC 30 -MX 40 for the mobile phone and the subscriber of the other country to provide data service. Time division switch in ASS-T 60 connected with IWF-speed matching unit in IWF 100-time division switch in modem unit-time division switch in ASS_T 60 connected with IWF-space division switch in INS 70- The time division switch in outgoing relay ASS_T 60 must be connected.

Thus, the IWF matching process performs data service outgoing routing processing (403) to investigate if there is a outgoing line connected to an available IWF speed matching processing device to be connected to the outgoing subscriber path within that route (404), If there is no outgoing line, other outgoing line connected in step 241, 242 of FIG. 2 (c) is cut (405) and abnormal release processing after step 206 of FIG. 2 (a) is performed. do.

If there is an idle IWF outgoing line in step 404, it occupies the outgoing line (406), and when the IWF 100 detects the occupancy of the incoming line and finds a data service call processing request, the modem to be used for the data service. Secure it and occupy the outgoing line connected to the modem.

When the IWF incoming line is occupied (407), the IWF matching process performs the space switch control processing 74 in the INS 70 and the time division switch control processing 54, 64 of the originating ASS_M 50 and the IWF matching ASS_T 60. Connect the outgoing line between the outgoing BSC relay line and the IWF outgoing line (408), the space switch control process (74) and the time division switch control process (64) of the outgoing ASS_T and IWF matched ASS_T. Connect the channel between the IWF outgoing lines (409). When the handover occurs due to the movement of the calling subscriber, the connection indication information is stored as a call so as to be processed (410).

Upon receiving the called subscriber information from the called exchange (411), the receiver checks if the called subscriber is idle (412), and if the incoming call is already busy, cuts out the outgoing line (413), and makes a call between the originating BSC relay line and the IWF outgoing line. 414 cuts the communication path between the IWF incoming line and the outgoing line (415) and cuts the IWF outgoing line (416) and then performs abnormal release processing after step 206 of FIG. 2 (a).

In step 412, if the called subscriber is idle, the called subscriber information, such as billing information, is stored (417), the alerting notification to the calling BSC 30 (418), data service between the calling terminal and the IWF modem Let's start the protocol.

When the answering subscriber of the called exchange, which has been listening to the call signal, responds and detects a response signal from the outgoing line (418), response processing after step 316 of FIG. 3 (b) is performed, and the response signal is transmitted to the IWF outgoing line. When transmitting (317) and detecting again at the incoming line (318) each is performed on only one relay line.

5 is a flowchart illustrating a data service call processing after a call according to the present invention.

3 and 4, the originating or terminating MS 10, which was in data service, moves, and the handover control process 53 renews the call path to the protocol processing for hard handover and the newly moved BSC. When the handover termination process is requested to the data service call control process that is connecting and controlling the call (501), the time-division switch used in the ASS_M (50) is disconnected and the new time-division switch is disconnected. The connected time division switch is connected (502), and the handover process is notified again by handover control process (503) to end the handover process.

In addition, unlike during a normal voice call, the supplementary service cannot be processed after the call, such as a conference call, call hold, transfer, or call waiting, so that the subscriber who was in a call or another third party may request additional service after the call. Chart 504 does not process this.

If the calling subscriber disconnects the call and receives the calling subscriber call release notification from the calling BSC 30 during the data service call (505), the BSC is notified of the release (506), and the paging process (73) in the INS 70 is received. The call state of the calling subscriber is registered as the dormant state (507), and the data service billing termination processing is performed by the AMS 82 in the CCS 80 (508). Then, the data service call type is checked (509), and in the case of the data service local call, the space switch control processing 74 in the INS 70 and the time division switch control processing 54, 64 of the originating ASS_M, the incoming ASS_M and the IWF matched ASS_T. ) To cut the call path between the calling BSC trunk line and the IWF outgoing line (510), the call path between the incoming BSC trunk line and the IWF outgoing line (511), and the call path between the IWF incoming line (512) and outgoing IWF. After cutting the mooring line (513), the release request is made to the incoming BSC (30) (514).

Upon receiving the release acknowledgment notification from the called BSC (515), the call status of the called subscriber is registered as dormant by the paging process 73 in the INS 70 (516) and the service is terminated from the dormant state.

In the case of the data service outgoing call in step 509, the outgoing line is disconnected (517), and the space switch control process 74 in the INS 70 and the time division switch control process of the originating ASS_M, outgoing ASS_T, and IWF matched ASS_T. Use (54, 64) to cut the call path between the originating BSC trunk line and the IWF outgoing line (518), the call path between the IWF incoming line and the outgoing line (519), and cut the IWF outgoing line (520) Terminate service in state.

As described above, in the present invention, the IWF is configured as an accessory device of the mobile exchange, and thus, data such as asynchronous data communication, fax service, and public data network search to the mobile subscriber registered at the local station in the existing voice mobile exchange with low development cost and effort. Investigate the service options of originating, terminating or outgoing subscribers in the mobile switching network in the mobile communication network to provide services and to prevent wasting of network devices occurring when the communication path between the mobile switching system and the IWF is lengthened. If it is determined that the data service request is made, the existing voice call control process is terminated and the data service call control process and the IWF matching process are driven to provide the data service with little effect on the existing voice call by adding a new data service. It was.
