BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing base station system mobile application part (BSSMAP) (hereinafter referred to as BSSMAP) in personal mobile communication. In particular, when a BSSMAP message is transmitted from a base station controller to a small personal communication exchange, The present invention relates to a BSSMAP processing method in a personal mobile communication suitable for implementing a GSM type BSSMAP protocol between a personal communication switch and a base station controller.

In this regard, mobile communication and personal communication services currently being carried out worldwide are about 70% to 80% of the GSM system is commercialized.

Therefore, in order to export mobile communication and personal communication switch, it is indispensable to implement GSM function, and for this purpose, management function such as radio resource allocation and release for matching between base station controllers and TDX-10 In this case, the paging function for the incoming call to the mobile subscriber and the handover processing function generated during the call are implemented.

Accordingly, an object of the present invention is to implement the BSSMAP protocol of the GSM method in the TDX-10 electronic switch, among the various protocols applied to the personal communication switch and the base station control period, so that the TDX-10 electronic switch can match with the base station controller. It is an object of the present invention to provide a BSSMAP processing method in personal mobile communication.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention for achieving the above object is as follows.

Referring to FIG. 1, FIG. 1 is a block diagram showing an embodiment of an exchange system to which a BSSMAP processing method is applied in personal portable communication according to the present invention, and the small personal communication exchange 100 processes a handover. The handover control processor 110, the mobile call control processor 120 performing the mobile call control function, and the BSSMAP control processor 130 interoperating with the handover control processor 110 and the mobile call control processor 120. The BSSMAP control processor 130 is interworked with the BSSMAP control processor 210 of the base station controller 200 via the CCITT No7 via CCITT No7.

The present invention thus achieved will be described in detail with reference to FIG.

First, the BSSMAP control processor 130 of the small personal communication exchange 100 has a function of encoding an internal interprocessor communication (IPC) in the GSM recommendation into a BSSMAP message and an IPC of the BSSMAP message received from the base station controller 200. Performs the function of encoding the number and performs the circuit identification number management function for the No. 7 signal link between the small personal communication exchange 100 and the base station controller 200, and the radio resources below the base station controller 200 cannot be used. It performs the function of releasing the call for abnormal handling procedures that occur in case.

In addition, the BSSMAP control processor 130 interoperates with the handover control processor 110 that processes the handover and the mobile call control processor 120 that performs the mobile call control function, and the base station controller 200 connects to the E1 link. Through the CCITT No7, it interworks with the BSSMAP control processor 210 of the base station controller 200 in the concept of peer-to-peer.

At this time, the BSSMAP functions defined in the GSM recommendation are classified as follows, and the corresponding functions are processed by the BSSMAP control processors 130 and 210.

1. Resource allocation

2. Handover Processing

3. Release of resources

4. Line state management between the small personal communication exchange 100 and the base station controller 200

5. Radio Resource Management

2 is a flowchart showing step by step an embodiment of a BSSMAP processing method in personal mobile communication according to the present invention.

In particular, the BSSMAP message is transmitted from the base station controller 200 to the small personal communication exchange 100.

First, when the BSSMAP message is received from the base station controller 200 to the small personal communication exchange 100, the timer is stopped and the handover is performed by analyzing whether the received BSSMAP message is a handover message or a mobile call processing related message by the message type. If the message, the BSSMAP message is decoded into an internal signal and transmitted to the handover control processor 110 before the message is transmitted to the handover control processor 110 (10, 12, 14, 16, 18).

After the signal is sent, the timer starts after the transition to the request message response state (20, 22).

Subsequently, the BSSMAP message received in step 14 is analyzed, and if the message is related to mobile call processing, the BSSMAP message is decoded into an internal signal and transmitted to the mobile call control processor 120 (24, 26).

After the signal is transmitted, the timer is started after the transition to the request message response state (28, 30).

As described above, the present invention implements the BSSMAP protocol of the GSM method, which is the most commercially available in the world, among the various protocols applied between the small personal communication exchange 100 and the base station controller 200 to the TDX-10 electronic switch. By doing so, the TDX-10 all-electronic exchange enables matching with the base station controller 200.
