Method for implementing data and speech transmitting method based on packet CDMA2000 access network

Abstract

The invention relates to a packet-based method for implementing concurrent data and voice services in CDMA2000 access network, concurrently providing voice service as data service is activated, and comprising the steps of: consulting for A2P bearing parameters between mobile terminal, base station and mobile switching center in the calling / called course, and characterized in that the consulting step comprises a step that: the base station carries base station-side A2p bearing parameters by added service request information to consult for bearing parameters; or the base station carries the base station-side A2p bearing parameters by assignment finishing information to consult for bearing parameters. As compared with the existing techniques, it can more effectively complete consultation forbearing parameters between MS, BS and MSCe.

Description

technical field

[0001] The present invention relates to a kind of method that realizes concurrent speech of data in CDMA2000 (the third generation CDMA) system, relate in particular to a kind of group-based The CDMA2000 access network realizes the method of data concurrent voice. The data concurrent voice referred to in the present invention refers specifically to the concurrent voice of the data service in the Active (active state), and does not cover the concurrent voice of the data service in the Dormant (dormant state). Background technique

[0002] 3G ALL IP BSS (three-generation all-IP base station subsystem) can use IP switching technology to access the CDMA2000 core network that implements LMSD (traditional mobile terminal domain). Compared with the traditional circuit domain MSS (Mobile Switching Subsystem) system, the biggest change of the CDMA2000 core network lies in the separation of call control and bearer, and the replacement of TDM (Time Division Multiplexin...
