Problems solved by technology

[0006] The relevant process of the existing communication protocol (Interoperability Specification (IOS) for CDMA2000 Access Network Interfaces-Part 3 Features (3G-IOS v5.0)) stipulates that the bearer format needs to be negotiated, but no negotiation method is proposed

Embodiment Construction

[0030] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] If the base station has not successfully negotiated with the mobile communication terminal when generating the list of bearer formats supported by the BSC, then in Image 6 There will be no bearer format corresponding to SO_Nego.

[0032] The present invention is used to realize the negotiation of the bearer format between the BS and the MSCe, that is, the BS generates a list of bearer formats supported by the BS, which includes two situations: 1. The BS has not yet known the list of bearer formats supported by the MGW when generating the list of bearer formats supported by the BS; 2. The BS already knows the list of bearer formats supported by the MGW when generating the list of bearer formats supported by the BS. In any case, a service option (SO) needs to be determined during the calling process to conduct service negotiation with th...

Abstract

The invention discloses a processing method to realize negotiation of load format in C net based on grouping, which is used to complete the negotiation of load format between the base station and the moving switch center simulator, and generates the load format list of moving switch center simulator, it includes following steps: when the base station generates the load format list of moving switch center simulator, if not know the supported load format list of media gateway, then generates said load format list according to the option of base station business and the selective business optionof moving terminal; if know the supported load format list, then generates said load format list according to the option of base station business, the selective business option of moving terminal andthe media gateway supported load format list.

Description

technical field [0001] The invention relates to a packet access method, in particular to a packet-based CDMA2000 access network implementation method for carrying out format negotiation. Background technique [0002] The packet-based CDMA2000 access network can use IP switching technology to access the CDMA2000 core network that implements the traditional mobile terminal domain (LMSD). Compared with the traditional circuit domain Mobile Switching Subsystem (MSS) system, the biggest change in the CDMA2000 core network lies in the separation of call control and bearer, replacing the Time Division Multiplexing (TDM) technology with the packet network technology, and the traditional Mobile Switching Center (MSC) ) network elements evolved into mobile switching center simulator (MSCe, MSC simulator) and media gateway (MGW), MSCe provides call control and mobility management functions, MGW provides media control functions, and provides transmission resources, with media stream man...
