Heterogeneous method and system for gsm/gprs network and wi-fi network

Abstract

A method and system for heterogeneous GSM / GPRS networks and Wi-Fi networks. The method includes: a terminal sends an access request to a base station subsystem through GSM / GPRS; the base station subsystem receives the access request and allocates network wireless resources to the terminal , the network wireless resources include TBF resources and Wi-Fi wireless resources; the terminal receives the network wireless resources allocated by the base station subsystem, turns on the Wi-Fi communication function, and obtains the base station by listening to the Beacon frames sent by the base station subsystem through Wi-Fi. subsystem, and sends a Wi-Fi association request message to the base station subsystem. The Wi-Fi association request message includes the MAC address of the terminal; the base station subsystem completes the Wi-Fi connection with the terminal based on the Wi-Fi association request message. Fi association sends an association response message to the terminal, and the terminal and the base station subsystem transmit data through Wi-Fi. The solution of the invention not only realizes the heterogeneous integration of GSM / GPRS network and Wi-Fi, provides users with continuous high-speed data services, but also has low implementation and operation costs.

Description

technical field [0001] The present invention relates to a method and system for heterogeneous wireless communication network fusion, in particular to a method and system for heterogeneous fusion of GSM / GPRS network and Wi-Fi network. Background technique [0002] The complementary advantages of "wired" and "wireless" technologies have promoted the convergence of fixed and mobile networks (FMC, Fixed-Mobile Convergence). FMC makes service provision independent of access technology and terminal equipment, that is, users can obtain the same service through different access networks. [0003] The existing GSM / GPRS (Global System for Mobile Communication, Global System for Mobile Communications / General Packet Radio Service, General Packet Radio Service) mobile communication network can provide wide-area coverage and support users' global roaming and fast movement, and can provide high-quality voice communication services, but data transmission The rate is generally low. Wi-Fi (...

AI Technical Summary

Problems solved by technology

This heterogeneous network integration solution is not designed to provide high-speed data services, but mainly to solve the problem of handover between different communication networks, and most of them are only for hotspot coverage, and need to deploy different network infrastructures, including different Network elements, such as AP (AccessPoint, access point), GANC (GANController, GAN controller), RADIUS (RemoteAuthenticationDial-InUserService, remote authentication dial-in user service), DHCP (DynamicHostControlProtocol, dynamic host control protocol), etc., and different Operation support system (such as security center, operation and maintenance center, user database, billing server, etc.), the implementation and operation cost is high
