[0046] figure 2 It is a model diagram of a 3G intra-office basic call in the first embodiment of the present invention, image 3is the flow chart of its call chain establishment. This embodiment assumes that there are two call processing boards in the system.

[0047] like figure 2 As shown, a basic 3G intra-office call is completed by the calling MCC, GMSC and called MCC. When a call is initiated, the calling side message is sent to the calling side MCC through the signaling interface board. MCC processes the call message, selects the calling side terminal and sends it to GMSC. The called MCC sends the control message to the signaling interface board after being processed by the called MCC, and transmits it to the called user. In this way, a complete intra-office call chain is established. This call chain consists of three half-calls, the calling MCC, the GMSC, and the called MCC. The calling MCC and GMSC are on one processing board, and the called MCC is on another pr...

[0061] Figure 4 It is a model diagram of a 3G inter-office basic call in the second embodiment of the present invention, Figure 5 is the flow chart of its call chain establishment. This embodiment still assumes that there are two call processing boards in the system.

[0062] interoffice call chain Figure 4 , consists of 3 MSC-Servers. From left to right are originating office, tandem office, and landing office. The half-calls at the originating office mainly include MCC, GMSC, and BICC, the two ends of the half-call at the tandem office are BICC, and the half-calls at the landing office are BICC and MCC. In the originating office, MCC and GMSC are on one processing board, and BICC and MCC are on the same processing board, but they may also be on different processing boards. In the tandem office, the two BICCs may be on the same processing board or on different processing boards. It is also possible for the BICC and MCC to be on the same processing board or different ...

Abstract

The invention discloses a half-call allocating method and call chain building method in multi- processing board system, firstly allocating calling number, roaming number and bureau-to-bureau calling identity code (CIC) to each call processing board; after receiving the calling information coming from the calling side, according to the calling number, determining call processing board of the calling MCC; when selecting a roaming number to a called user, giving priority to the selection of the roaming number processed by the processing board where the calling MCC exists; otherwise adopting rotary-selecting method for selection; when according to the called number, selecting bureau-to-bureau CIC, giving priority to the selection of CIC processed by the processing board where front half-call exists; otherwise adopting rotary-selecting mode for selection; based on the above method, it can build various call chains and make all the half-calls uniformly distributed on the processing boards, solving the problem of complex calling distribution of multiprocessing board system and better supporting mobile basic service and various supplementary services.

Description

technical field [0001] The present invention relates to the half-call in communication field, specifically, relate to the NGN (next generation network, such as WCDMA / CDMA2000 / TD-SCDMA / SOFTSWITCH) system in the communication field in the multi-processing board call system such as MGC (media gateway controller) The distribution method of the half-call and the establishment method of the call chain. Background technique [0002] With the development of network technology, the separation of bearer, control and service becomes the trend of network development. In the WCDMA R4 system, by introducing MGW, the separation of bearer and control is completed, the bearer is managed by the MGW, and the call control is completed by the MSC-Server. In order to complete the establishment of the inter-office bearer, the MSC-Server introduces the BICC (Bearer Independent Call Control, bearer independent call control) protocol. At the same time, in order to intercommunicate with the traditio...
