The system for the IMT-2000 service includes a home location register (HLR) (15), a mobile switching center (MSC) (14), a base station controller (13), a base station (12), and a wired network toll. Exchange 18 and Local exchange 17 are included.

The service control point (SCP) 19 communicates with the HLR 15 through the No. 7 signal network 20 to inquire the mobile subscriber's location and status information.

The mobile switching center 14 communicates with the service control system (SCP) 19 and the Toll exchanger 18 through the No. 7 signal network 20, and is wired from the service control system (SCP) 19. When the call is requested by the telephone, the call is transferred to the Toll exchanger 18, and the call is transferred to the mobile switching center in the case of the mobile phone and the voice mail service (VMS).

FIG. 2 is a block diagram showing the basic configuration of the personal tracking call delivery service processing rescue device constituting the present invention. The MSC interface unit 25 performs an interface function between the mobile switching center 14 and the Toll exchanger 18. FIG. And a Toll exchanger interface face portion 28.

The MSC interface unit 25 receives and decodes an InitialDP message from an outgoing mobile switching center (MSC), sends it to the service processing unit 26, and receives an incoming call request from the service processing unit 26 to the mobile phone. This function encodes and transmits a connection message to a center (MSC). This ultimately leads to the Public Switching Mobile Network (PLMN) 22, which includes the Incoming Mobile Switching Center (MSC), or the Incoming Mobile Switching Center (MSC) associated with the VMS if the destination routing address is a VMS (23). Is connected.

The Toll exchanger interface unit 25 receives and decodes an InitialDP message from the originating Toll exchanger, sends it to the service processing unit 26, and receives a call request from the service processing unit 26 with a wired telephone to connect to the originating Toll exchanger. Encode and send a message. It is ultimately connected to a Public Switched Telephone Network (PSTN) 21 (Public Switched Telephone Network) that includes the incoming Toll exchange.

In FIG. 2, the HLR interface unit 27 inquires the location information and the status information of the called subscriber to the subscriber location register (HLR). The HLR interface unit 27 encodes and transmits an Any Time Interrogation message including its service control system address, request information (subscriber location, status), and subscriber ID, and transmits the corresponding subscriber address from the subscriber location register (HLR). Receives and decodes Any Time Interrogation ack messages containing location information and status The information transmitted and received with the subscriber location register (HLR) is provided to the service processor 26.

In FIG. 2, the time information unit 29 provides the current time to the service processing unit 26, and the database 30 provides the ID, Home Zone information, Office Zone information, and call forwarding information of the subscriber who subscribed to the tracking service. It performs the function of saving and managing. Here, the zone range is selected by using one of Cell Id, Location Area Identity (LAI), and Geographical information.

In addition, in FIG. 2, the service processor 26 performs a call transfer function in consideration of the location, state, and time of the subscriber. The service processor 26 performs a call forwarding service according to the conditions defined in Table 1.

Information area parameter Call priority number Priority number busy or no answer Location information Home zone -VLR number-Geographic information-Cell or location area id -Home phone number -Mobile phone number Office Zone -VLR number-Geographic information-Cell or location area id -Office number -Mobile phone number Subscriber requirements Meetings and business trips -Mobile phone number Voicemail At power off Irrelevant -Subscribers register and change time -09:00 to 18:00: office phone number-21:00 to 08:00: home phone number-other times: voicemail -Mobile phone number-mobile phone number

In Table 1, the location information is divided into a home zone and an office zone, and when a called subscriber is located in the corresponding zone, the call is forwarded to the incoming priority number. If the priority number is busy or unanswered (until the bell rings 3-4 times), the call is sent to the mobile phone or voicemail.

When a subscriber registers for a meeting or a business trip, the call is unconditionally forwarded to the mobile phone.

When the terminal is powered off, the subscriber transfers the call according to the registered time according to its life pattern. If the priority number is busy or unanswered (until the bell rings 3-4 times), the call is forwarded to the mobile phone. The subscriber can change when his life pattern changes.

3 is a flow chart performed by the service processor 26 for processing a personal tracking call delivery service in an IMT-2000 wired and wireless network according to the present invention.

When the operation of the service processing unit starts (step 101) and receives an InitialDP (Initial Detection Point) from the originating mobile switching center or the originating toll exchange (step 102), the service is analyzed by analyzing the service key of the received message. After determining whether it is a personal tracking call forwarding service (step 103), if the service matches, the HLR interface unit 27 sends an Any Time Interrogation message including its SCP address, information to be requested (subscriber location and status), and subscriber ID. Request a transfer (step 104). The Any Time Interrogation ack message, which is a result of the query from the HLR interface unit 27 to the subscriber location register (HLR), is received (step 105). The received Any Time Interrogation ack message includes subscriber location information (Location Number, CellIdOrLAI, Geographical Information, Age Of Location Information, VLR Number) and subscriber status (Busy, NotReachable, Idle).

In the received information, the location area ID is compared with the Home Zone and Office Zone registered in the database 30 (step 106). If the current location matches the Home Zone, the incoming message routing to the Toll exchange interface unit 28 is routed. Set the number to the home phone number and request transmission to the Toll exchange (step 107).

However, if the current location matches the Office Zone, the toll exchange interface unit 28 sets the incoming routing number of the connection message to the office telephone number and requests transmission to the corresponding toll exchange (step 108).

In steps 107 and 108, if the subscriber is busy or unanswered (steps 110 and 112), the destination routing number of the access message is set to the mobile phone number and requested to be transmitted to the corresponding MSC exchange (step 111). 122). Otherwise, the process ends immediately (step 122).

In step 106, if the current location is not the Home Zone and the Office Zone, it is determined whether the subscriber status is the meeting or the business trip and the power off (step 109). As a result, if the subscriber status is determined to be a meeting or a business trip, the destination routing number of the connection message is set to the MSC interface unit 25 as a mobile phone number, the transfer is requested to the corresponding MSC exchange (step 113), and the process ends (step 122). ).

On the other hand, if the subscriber state is powered off, the current time information is queried from the time information unit 29 (step 114) and compared with the time information of the subscriber registered in the database 30 (step 115).

If the current time is between 09 and 18 o'clock, the destination routing number of the connection message is set as the office telephone number to the Toll exchange interface unit 28 and requested to be transmitted to the corresponding Toll exchange (step 118). If the current time is between 21 and 08 o'clock, the destination routing number of the connection message is set to the home telephone number to the Toll exchange interface unit 28 and requested to be transmitted to the corresponding Toll exchange (step 117).

If the subscriber is busy or unanswered in steps 117 and 118 (steps 119 and 121), the destination routing number of the access message is set to the mobile phone number and requested to be transmitted to the corresponding MSC exchange (step 121), and the process ends (step 122). ). Otherwise it ends immediately (step 122). At other times, the MSC interface unit 25 sets the destination routing number of the Connect message to the corresponding destination MSC to which the VMS belongs, requests transmission to the corresponding MSC exchange (step 116), and terminates (step 122). In this case, the transmitted and received message is an international standardized Mobile Application Protocol (MAP) message. However, the AnyTimeInterrogation ack message includes the incoming MSC number of the subscriber's VMS when the UE is powered off.

4A is a scenario procedure diagram provided when a service is requested by a mobile terminal according to an embodiment of the present invention. The TA SETUP message (Terminal Association SETUP) of call setup includes signal channel setup, cell status report, user ID acquisition and authentication, Temporary Mobile User Identity (TMUI) Assignment, terminal state update, etc. is a procedure that performs before the call is initiated.

When the call is initiated, the IMT-2000 calling terminal requests a call connection to the calling mobile switching center by the SETUP message 42.

The calling mobile switching center sends a CALL PROCEEDING message 43 to the calling terminal to inform that the received SETUP message 42 is valid and authenticated.

Accordingly, an access link is established 44 between an originating terminal and an originating mobile switching center. During this access link, a specific call channel between an originating base station controller (RNC) and an originating mobile switching center (MSC) and An access link setup message for requesting wireless channel setup between the terminal and the base station and an access link setup message, which is a setup completion message, are used.

As the access link is established, the originating mobile switching center detects the trigger of the present invention and sends an InitialDP message 45 to the service control system 19 requesting the service logic to be driven, and the service control system (SCP) corresponding subscriber. In order to inquire the location and status information of the Any Time Interrogation message 46 is sent to the subscriber location register (15).

The subscriber location register (HLR) 15 sends an Any Time Interrogation ack message 50 to the service control system 19 to notify the location and status information that is the result of paging performance 48 for the called party. If information is registered in the subscriber location register 15 that the terminal is powered off, the number of the incoming mobile switching center to which the corresponding voicemail service (VMS) is connected is included. The subscriber location register 15 is informed of the result of paging performance 48 using the destination mobile switching center (MSC), the Provide Subscriber Info message 47 and the Provide Subscriber Info ack message 49.

Subsequently, the service control system 19 sets the corresponding number in the destination routing address of the access message 51 according to the result of the tracking service control unit 24, and sends the corresponding number to the calling mobile switching center, and the calling mobile switching center sends the incoming routing address. If is a wireless call transfers the call using the IAM message 52 to the corresponding mobile switching center. As a result, the terminating mobile switching center delivers the IAM message 53 to the terminating base station controller (RNC).

On the other hand, the outgoing mobile switching center transfers the call using the IAM message 54 to the called toll exchange when the called routing address is a wired call, and the called toll exchange sends the IAM message 53 to the called base station controller (RNC). To pass.

FIG. 4B is a scenario procedure diagram when providing a service request in a wired terminal according to an embodiment of the present invention. When a call is initiated, the wired terminal requests a call connection to an originating local exchange by a SETUP message 61. The IAM message 62 is sent to the calling Toll exchanger, and the CALL PROCEEDING message 63 is sent to the wired terminal, indicating that the received SETUP message 61 is valid. The originating Toll interrogator receiving the IAM message 62 detects the trigger of the present invention and sends an InitialDP message 45 to the service control system 19 to request service logic driving. The procedure below is the same as in FIG. 4A.

According to the present invention as described above, when the existing mobile subscriber is located in the home or office even when the mobile terminal is turned on, the mobile device can receive a call transfer service. Eliminate the hassle.

In addition, when a mobile subscriber registers a meeting or a business trip, the call is transferred to the existing mobile phone, and when the power is turned off, the call can be switched according to the user's life pattern, thereby providing convenience to the user.
