Call processing method, system and mobile switching center server

Abstract

The embodiment of the invention provides a call processing method, a system and a mobile switching center server. The call processing method include that: a first MSS receives a call sent by a first PSTN through a circuit selected by the first PSTN; when the circuit selected by the first PSTN is a circuit managed by the first MSS between a first MGW and the first PSTN, the first MSS processes the call; when the circuit selected by the first PSTN is a circuit managed by a second MSS between a first MGW and the first PSTN, the first MSS forwards the call to the second MSS such that the second MSS processes the call. According to the embodiment of the invention, different MSSs in a MSCPool use a same signaling point to communicate with the PSTN can be realized, different sections of the circuit between the MGW and the PSTN are managed respectively, and carrying out disaster recovery on a function of a gateway MSC can be realized.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a call processing method, system and mobile switching center server. Background technique [0002] The prior art proposes a networking mode completely different from traditional networking: a radio network controller (Radio Network Controller; hereinafter referred to as: RNC) / base station controller (hereinafter referred to as: BSC) can be connected to multiple In a serving mobile switching center (Mobile Switching Center; hereinafter referred to as: MSC), the above-mentioned multiple serving MSCs form an MSC pool (MSC Pool). [0003] The MSC with many existing networks can not only connect to the access side such as RNC / BSC as an end office, but also connect to the Public Switched Telephone Network (Public Switched Telephone Network; hereinafter referred to as: PSTN) or other public land mobile networks (Public Land) as a gateway office.

Problems solved by technology

[0004] However, in the prior art, when G / V-integrated MSCs form an MSC Pool, since each MSC server (MSC Server; hereinafter referred to as: MSS) in the MSC Pool uses different signaling points to communicate with the PSTN or PLMN, the MSC Pool can only perform disaster recovery for the functions of the end office, but not for the function of the gateway office.
