Embodiment Construction

[0031] figure 1 It is a system solution for the combination of two networks of WLAN+CDMA. figure 1 , it can be seen that it is basically divided into three parts, CDMA access network, WLAN access network, and home network.

[0032] Below to figure 1 As an example, the function of the system of the present invention will be described in detail.

[0033] The present invention better solves the problem of network coverage, figure 1 Among them, the coverage areas of APs in WLAN are mainly concentrated in hot spots such as airports and star hotels, and their coverage areas are discontinuous. In the CDMA network, the service area is covered by BTS, and its wide coverage just makes up for this shortcoming. Use AP's high-speed network in hot spots, and use CDMA's wide-coverage network in common areas.

[0034] Authentication is the main problem faced by telecom-grade applications. In the present invention, for users in the WLAN access mode, the HLR does not participate in the au...

Abstract

The access system is based on combination of CDMA system and wireless local area network. Base station transceiver, base station controller, packet data service node, server of validation authentication and charge, resided proxy server, mobile switching center etc. constitute CDMA network. The said wireless access point through dedicated line is connected to packet data service directly. The packet data service node includes access process unit for WLAN users in terminals, which is connected to CDMA user access unit, user data and RADIUS interface respectively. The invention possesses features of low cost, easy of building network and combination of wide coverage of cdma-1x system and high bandwidth of WLAN.

Description

technical field [0001] The invention relates to a solution for providing packet domain access services for mobile users through the combination of wireless local area network (WLAN) and CDMA network. Background technique [0002] Wireless local area network (Wireless LAN hereinafter referred to as WLAN) is the product of the combination of computer network and wireless communication technology. WLAN is characterized by low price, flexible networking, support for high-speed wireless data access and open frequency bands, and is suitable for applications in hot spots such as airports and hotels. However, WLAN has a limited coverage and can only provide services in hotspot areas, and cannot provide terminal authentication and billing, so it cannot provide user management; while CDMA network has the characteristics of wide area coverage, its authentication and billing The mechanism is relatively complete, but due to bandwidth limitations, it can only provide end users with acces...
