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, and particularly, when a BSSMAP message is transmitted from a small personal communication exchange to a base station controller. The present invention relates to a BSSNAP processing method in a personal mobile communication suitable for implementing a GSM type BSSMAP protocol between a personal communication exchange and a base station controller.

In this regard, the 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.

Therefore, an object of the present invention is to implement the BSSMAP protocol of the GSM method among the various protocols applied between the personal communication exchange and the base station controller in the TDX-10 electronic switch, so that the TDX-10 electronic switch can be matched with the base station controller. The present invention provides a method for processing BSSMAP 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 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. A handover control processor (110), a mobile call control processor (120) performing a mobile call control function, and a BSSMAP control processor (130) interoperating with the handover control processor (110) and the mobile call control processor (120). BSSMAP control processor 130 is interworked with the BSSMAP control processor 210 of the base station controller 200 via the CCITT No. 7 via the CCITT No. 7 in the concept of peer-to-peer.

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

First, the BSSHAP 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 decoding the signal, 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 handles 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 No. 7, the concept of a peer-to-peer interworks with the BSSMAP control processor 210 of the base station controller 200.

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 small personal communication exchange 100 to the base station controller 200.

First, the BSSMAP message signal is received from the upper block in the form of an internal signal, and the process ID (ID) of the upper block is stored (002).

Next, a line identification number for checking a signal link for transmitting to the base station controller 200 by checking the assigned line number in the upper block is found through the database and allocated (003).

After storing the information necessary for the transmission and reception of the signal with the upper block, the base station controller 200 encodes the BSSMAP message as usable by the BSSM 200 (004).

Subsequently, an information header for communicating the encoded BSSMAP message with a Signaling Connection Control Part (SCCP), which is a No. 7 processing block, is created (005).

In addition, after message formatting is completed, a state transition is performed and a mobile call processing procedure is performed by checking such a state when receiving a next received message (006).

After the state transition, it transmits a message to the base station controller 200 and starts a timer to wait for a message to be received (007, 008).

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.
