Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] The multi-module MSC of this embodiment includes MSC modules A, B, and C, and the signaling link and ground circuit configuration between a large-capacity BSC and the multi-module MSC are as follows figure 1 As shown, the dotted line in the figure is the signaling link, and the solid line is the ground circuit. Among them, the signaling link is connected to two MSC modules A and B, and the ground circuit is connected to three MSC modules A, B and C.

[0027] Please refer to figure 2 , in the above-mentioned system, after the signaling link of an MSC module receives the service request message of the mobile phone call, it is sent through MTP2 (message transfer part, signaling link layer), MTP3 (message transfer part, network management layer) Go to the SCCP routing process (SCCPSCRC) of this module to decode the complete third-layer message of...

Abstract

The invention discloses a call processing method in a multi-module MSC supporting large-capacity BSC system. Each MSC module evaluates the load of the module in real time. The load of the MSC module selects the module for business processing, and pre-occupies an idle ground circuit configured for the selected module in the database, sends a message to the selected module to establish an SCCP connection, and communicates the A port process and call control The process is also established on the selected module, and the received follow-up message of the SCCP connection of the call and the ground circuit management message received by the A port are sent to the module for processing. The invention establishes the SCCP connection on the MSC module where the ground circuit is located, so that the SCCP connection, the A port and the CC are established on the same module, which simplifies the call processing inside the MSC and can realize the matching of multi-module MSC processing capabilities.

Description

technical field [0001] The present invention relates to the switching field of mobile communication (including GSM, CDMA, 3G), in particular to the A interface signaling of the mobile exchange and the method for signaling connection and service capacity coordination in the field of No. 7 SCCP (Signaling Connection Control Part) signaling . Background technique [0002] In the technical specifications of GSM (and CDMA, 3G), the interface between MSC (mobile switching center, or switching office) and BSC (base station controller, called BS in CDMA) is called A port. ) In the field of mobile switching, the A port is defined by the communication standard, and the standardization of the A port provides a reliable guarantee for the respective development of MSC and BSC equipment. [0003] At present, each MSC supports about 100,000 to 400,000 users. Almost all MSC equipment manufacturers use multi-module technology. Support 400,000 mobile users. Each module of the same MSC usua...
