Problems solved by technology

[0004] Although the PHS packet data service can be realized by deploying the PHS packet server for the PHS network separately on the core network side, the solution obviously has the following deficiencies: First, the PHS packet server needs to be deployed separately for the PHS network, which increases the operator's network construction and Network equipment maintenance costs; second, it is not conducive to network expansion and integration with 3G networks

Abstract

The present invention relates to a system and method by which PHS network is connected in 3G core network basing PS domain. By connecting the voice exchange center in PHS network subsystem to SGSN in 3G core network basing PS domain subsystem, namely LAPB and X25 protocol processing modules of the network element equipment, the present invention realizes that PHS network is connected in 3G core network basing PS domain, and uses 3G core network basing PS domain to provide exchange of grouped data and routing function for PHS network, thereby realizing PHS grouped data service.

Description

technical field [0001] The present invention relates to a system and method for accessing a PHS network to a 3G core network packet domain, which realizes the integration of the existing PHS network and the 3G network, and provides packet data services for users of PHS (Personal Handy-phone System), that is, personal hand-held telephone systems. Especially in the packet domain of the 3G core network, by extending the function of the SGSN (Serving GPRSSupport Node) in the packet domain of the 3G core network, that is, the function of the serving GPRS support node, the SGSN supports PHS network access, and realizes the connection between the PHS network and the 3G network in the packet domain of the core network. fusion. Background technique [0002] PHS packet data service refers to providing PHS users with packet data such as web browsing, e-mail, and chat by upgrading PHS base stations, adding PHS packet data core network switching equipment and upgrading PHS terminals on t...
