Embodiment Construction

[0049] The present invention includes four core algorithms, which respectively realize the call-initiating flow in the data service activation state and the concurrent voice call flow in the data service activation state and voice in different situations. These four algorithms are described respectively according to the two cases of concurrent voice calling in the data service active state and concurrent voice calling in the data service active state.

[0050] 1. The data service is in the active state, and the voice service is concurrently sent at this time. The BS carries the A2p bearer format information element in the Additional Service Request message.

[0051] The BS sends an Additional Service Request message to the MSCe, and starts a timer T303 at the same time. Because the BS already knows the bearer format and address, the BS carries the A2p bearer parameters in this message. The bearer parameters include the A2p Bearer Session-Level Parameters information unit and...

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 for bearing 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...
