Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The fusion system model corresponding to the present invention is as follows figure 1 . Among them, the terminal has two independent air interfaces, which can be connected to either the CDMA2000 system or the WLAN system, and has the function of autonomously switching between the two systems. The base station subsystem provides the air interface of the CDMA2000 system, and realizes the signaling exchange and data packet exchange and control functions of the R_P interface with the packet data service node. The access point manages the wireless network access based on the IEEE802.11 protocol, and provides the PPPoE network access function, and realizes the signaling exchange and data packet exchange and control functions of the R_P interface with the packet data service node. The packet data service node is an interface connecting the wireless ...

Abstract

The method includes following steps. Terminal has detected a WLAN system, and initiates reconnection to access point in WLAN system. After air channel has built, terminal sands out PPPoE data packet. IP interface connection between access point and packet data service node is built. The packet data service node determines if this connection is a new connection. If yse, new PPP connection is built, and user's right authentication is carried out, if there is data needed to send, user's data - PPPoE data packet is transmitted between terminal and the packet data service node. Connection built for terminal between packet data service node in CDMA2000 and R_P interface in base station is disconnected. The invented method provides combination of wide coverage of CDMA2000 and high-speed data connection of WLAN, realizing continuous data connection and seamless roam between CDMA2000 and WLAN.

Description

technical field [0001] The invention relates to a switching method between a CDMA2000 system and a wireless local area network (WLAN) system, so as to realize the fusion of the CDMA2000 system and the WLAN system, and realize the seamless roaming of a mobile terminal in the fusion system. Background technique [0002] Code Division Multiple Access (CDMA) is a multiple access method based on wideband spread spectrum technology, and is one of the multiple access modulation technologies commonly used in mobile communications. The CDMA2000 system follows the IS-2000 standard and is the first stage of the development of CDMA2000 cellular mobile communication technology. It adopts a spreading rate of 1.2288Mbps, supports packet data services, and can provide a packet data transmission rate of 144Kbps. The PPP protocol is adopted between the MS and the PDSN to transmit PPP data frames in the HDLC encapsulation format. [0003] Wireless local area network (WLAN) is the product of t...
