Embodiment 1

[0228] Figure 8 It is a schematic diagram of the implementation flow of the user switching from the packet domain to the circuit domain in the first embodiment. In this embodiment, the core network uses WCDMA R4 as an example, and the packet access network uses SAE as an example for illustration. As shown in the figure, when the user is in the MSC (comprising the MSC server and the media gateway MGW) under the control of the SAE packet network to switch when talking, may include the following steps:

[0229] Step 801, the eNodeB sends a handover / migration request to the MME.

[0230] Step 802, the MME sends a handover / relocation request to the packet access unit.

[0231] Step 803, the packet access unit sends a handover / migration request to the MSC server.

[0232] Step 804, the MSC server finds that the target area is located in the CS domain coverage area under its jurisdiction, and the MSC server sends a handover / relocation request to the BSC / RNC corresponding to the ha...

Embodiment 2

[0252] Figure 11 It is a schematic diagram of the implementation flow of the user switching from the circuit domain to the packet domain in the second embodiment. In this embodiment, the core network takes WCDMA R4 as an example. As shown in the figure, when the user is calling through the circuit domain access under the control of the MSC Handover, where the handover target area is located in the SAE packet access network, may include the following steps:

[0253] Step 1101, RNC / BSC sends a handover / relocation request to MSC, carrying target area information.

[0254] Step 1102, the MSC sends a handover / relocation request to the packet access unit according to the packet access unit corresponding to the target area information.

[0255] Step 1103, the packet access unit sends to the SAE network to initiate the establishment of a packet access bearer for handover.

[0256] Step 1104, the packet access unit returns a handover / relocation request response to the MSC, carrying ...

Embodiment 3

[0265] Figure 12 It is a schematic diagram of the implementation flow of the user switching from the circuit domain to the packet domain in the third embodiment. In this embodiment, the core network takes WCDMA R4 as an example. As shown in the figure, when the user is making a call through the circuit domain access under the control of the MSC Handover, where the handover target area is located in the SAE packet access network, may include the following steps:

[0266] Step 1201, RNC / BSC sends a handover / relocation request to MSC, carrying target area information.

[0267] Step 1202, the MSC sends a handover / relocation request to the packet access unit according to the packet access unit corresponding to the target area information.

[0268] Step 1203, the packet access unit sends to the PDN GW in the SAE network to initiate establishment of a packet access bearer for carrying media for handover. Specifically, the packet access unit sends a service request to the PCRF in t...

Abstract

The invention discloses a user service switch system, a device and a method, which include: a packet access network, a mobile switching centre, a user device, a packet access unit, and a possible circuit domain. The packet access unit is used for ensuring the signaling path between the packet access network in the packet domain and the mobile switching centre in circuit domain, and the load between the management user device and the mobile switching centre; the packet access network is used for handling the switch of the circuit domain overlay area or the packet domain overlay area; the circuit domain assess network is used for handling the switch of the circuit domain overlay area or the packet domain overlay area; the mobile switching centre is used for handling the switch from the packet access network or to the destination of packet access network. The invention ensures the use can carry out the switches of packet overlay area or circuit domain overlay area as destination area or source area when calling, under the control of MSC, which is good for the operator to sufficiently use the packet network overlay to provide more continuous services for users, thereby improving the use efficiency of network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a system, device and method for switching user services. Background technique [0002] There are many types of current wireless networks, including GSM / WCDMA (Global System for Mobile Communications / Wireless Code Division Multiple Access, Global System for Mobile Communications / Wireless Code Division Multiple Access), CDMA 2000 (Code Division Multiple Access2000, Code Division Multiple Access) Address Access 2000) and TS-CDMA (Time division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access). Both can provide users with mobile services, and they have similarities in architecture and business capabilities. The following uses WCDMA as an example to describe the architecture of wireless networks. figure 1 It is a schematic diagram of the WCDMA network architecture in 3GPP TS23.002 V640, as shown in the figure, the relevant entities r...
