Abstract

A transmission method of circuit data packet in a CDMA2000 mobile terminal domain is provided, comprising: establishing conversation between a source base station and a target base station, determining a user circuit data code by the source base station and / or the target source base station, and determining a load format parameter; undergoing negotiation of the load format by the source base station and / or the target base station and a mobile exchange centre simulator, and establishing real time transmission protocol conversation; in a user plane service layer, packing the circuit data to real time transmission protocol packet according to the determined load format by the source base station and the target base station, and sending the real time transmission protocol packet to a target base station and a source base station on the opposite end through media gateway treatment; receiving the real time transmission protocol packet at the target base station and the source base station of the opposite end, analyzing user data on the user plane service layer, and processing the real time transmission protocol packet according to the load format to obtain circuit data payload; therefore, the transmission method can effectively solve the transmission problem of Alp interface out-band negotiation circuit data load format parameter and circuit data on real time transmission protocol packet.

Description

technical field [0001] The present invention relates to a transmission method of circuit data (Circuit Data) grouping on the Internet protocol network, in particular to a transmission method of circuit data grouping on the Internet protocol network realized in the CDMA2000 traditional mobile terminal domain. Background technique [0002] The packet-based CDMA2000 base station subsystem (Base Station Subsystem: BSS) can use the Internet Protocol (Internet Protocol: IP) switching technology to access the softswitch-based CDMA2000 core network. Compared with the traditional circuit domain mobile switching subsystem (Mobile Switching Subsystem: MSS) system, the biggest change of the softswitch-based CDMA2000 core network is that call control and bearer are separated, and packet network technology is used to replace time division multiplexing ( Time Division Multiplexing: TDM) technology, traditional Mobile Switching Center (Mobile Switching Center: MSC) network elements evolve i...
