Method for supporting mobile terminal to move between base stations with diversity of protocol versions

Abstract

A method for supporting a mobile terminal to move between base stations with different protocol versions comprises following steps: S102, one ore more sets of dialog configuration information are negotiated by a base station controller with the mobile terminal according to types of mobile terminal protocol versions; S104, in call process, according to types of mobile terminal protocol versions, the dialog configuration information which are used by the mobile terminal and the base station protocol version type of a call cell in the mobile terminal, the base station controller determines to whether or not establish connection with the mobile terminal or control whether or not the mobile terminal switch to another more adaptive dialog configuration information; S106, in handoff process, according to types of mobile terminal protocol versions, the dialog configuration information which are used by the mobile terminal and the pilot frequency intensity relation of the base station belonging to different protocol versions in routing updating messages reported by the mobile terminal, the base station controller determines to whether or not select a part of pilot frequency to switch or firstly control whether or not the mobile terminal switch to another more adaptive dialog configuration information.

Description

technical field [0001] The present invention relates to the communication field, and more specifically relates to a method for supporting a mobile terminal to move between base stations with different protocol versions. Background technique [0002] CDMA2000 1xEV-DO (IS-856) is a branch of the CDMA standard family, which includes a series of evolving protocols. Newer IS-856 protocol versions not only contain the features and functions of previous versions, but also improve and add new features. In order to support new features, both the base station system and the mobile terminal usually need to be upgraded in terms of hardware and software. [0003] IS-856 version O and version A are two standards that have appeared successively in this protocol family. Compared with version O, version A has been greatly improved. The enhancement of physical layer and MAC layer protocol can support higher forward and reverse data transmission rate, More effectively reduce the interference...

AI Technical Summary

Problems solved by technology

For this mixed configuration networking method, there is the following problem: when a mobile terminal with protocol version O moves between base stations with different protocol versions, it needs to decide which wireless parameter configuration to use to be compatible. When a mobile terminal of protocol version A moves from a base station with a higher protocol version to a base station with a lower protocol version, it may cause call drop because the signaling format or data transmission format is not supported by the base station. When the base station moves to a base station with a higher protocol version, it may not be able to apply various enhanced features due to the limitation of wireless parameter configuration
