Embodiment 1

[0058] This embodiment takes the network interconnection structure shown in Figure 1 as an example, and specifically describes the use of the method of the present invention. Figure 3 is a schematic flow chart of the method of this embodiment. As shown in Figure 3, the method includes the following steps:

[0059] Step S301 : the terminal 400 reports frequency measurement information to the access network 301 of the HRPD network 300 .

[0060] Compared with the CDMA2000 1x network, the HPRD network can provide higher forward and reverse links, especially the forward link can reach up to 2.4576Mbps, which better supports streaming media services. Typical services of HRPD networks include: enterprise Virtual private network access to virtual private network (Virtual Private Network, referred to as VPN), email, MP3, Wet browsing or e-commerce, audio or video information service (Video-On-Demand, referred to as VOD), digital TV, videophone, video conferencing etc.

Embodiment 2

[0100] This embodiment takes the network switching of the network interconnection structure shown in FIG. 2 as an example, and specifically describes the use of the method of the present invention. FIG. 5 is a schematic flow chart of the method of this embodiment. As shown in FIG. 5, the method includes the following steps:

[0101] Step S501 : the terminal 400 reports frequency measurement information to the access network 301 of the HRPD network 300 .

[0102] Step S502: The access network 301 decides whether to switch to the CDMA2000 1x network according to the pilot measurement information, and if so, executes step S503; otherwise, executes step S509.

[0103] The above two steps are the same as step S301 and step S302 in the first embodiment.

[0104] Step S503: The access network 301 decides the handover destination cell of the CDMA2000 1x network to be handed over to, and notifies the terminal 400 to handover to the CDMA2000 1x network, and sends a handover request to t...

Embodiment 3

[0134] Fig. 7 is the structural representation of the described communication system of present embodiment, as shown in Fig. 7, this communication system comprises: CDMA2000 1x network 205, HRPD network 303 and the terminal 400 in HRPD network 303, wherein CDMA2000 1x network 205 comprises: MSC202 , and BS201 and BS203 respectively connected to the MSC and controlled by the MSC; the HRPD network 303 includes: a packet data service node 304 providing gateway service functions; connected to the packet data service node 304 for forwarding the wireless subsystem The packet control unit 305 of the message between the packet data service node 304; connected with the packet control unit 305, controlled by the packet control unit 305, the terminal 400 is connected to the access network device 302 of the HRPD network; the terminal 400 is located There are cell 100 and cell 104 where BS201 and BS203 respectively exist, and both BS201 and BS203 belong to the CDMA2000 1x network.

Abstract

The invention relates to a network switch method and communication network system. Wherein, said method comprises: HPRD network sends network switch request to the CDMA2000 lx network, and reports the region marks and pilot measure information of at least two BS regions that need to be switched to CDMA2000 lx network; each BS distributes service channel for the terminal; CDMA2000 lx network instructs the HRPD network to send switch command to the terminal and inform the terminal about the service channel distributed by BS; terminal receives said switch command, based on the information of service channel, to catch the service channel distributed at any region by any BS. The invention can reduce the time delay of catching service channel when the terminal at the edge of several BS and processing network switch, to improve the reliability of network switch.

Description

technical field [0001] The invention relates to the communication field, in particular to a network switching method and a communication network system for CS voice switching from HRPD network to CDMA2000 1x network. Background technique [0002] Code Division Multiple Access (CDMA) technology is a new and mature wireless communication technology based on spread spectrum technology. In recent years, with the increasing rate of CDMA data service user penetration, the slower growth rate has become the bottleneck of CDMA data service development compared to the smaller scale of CDMA users. [0003] High-speed data (High Rate Packet Data, HRPD for short) technology came into being driven by such a market. Although the data carrying capacity of CDMA2000 1x has been greatly improved, there are still air interfaces for rich multimedia services. on the bottleneck. In order to solve the bottleneck problem of the air interface, the HRPD technology is proposed. HRPD technology is an...
