Embodiment 1

[0022] This embodiment provides a method for switching services, and the method for switching services is applicable to a network capable of performing CS services, such as a 2G / 3G network. The subject of executing the method for switching services is a device for switching services, and the device for switching services may be set in the SGSN (Serving General Packet Radio Service Support, General Packet Radio Service Node) of the PS domain where the terminal is registered.

[0023] Such as figure 1 Shown is a schematic flow chart of the method for switching services according to this embodiment.

[0024] Step 100, when the terminal is performing CS service and receives a connection establishment request of PS service with higher priority than CS service, determine the network resources to be occupied by PS service.

[0025] Specifically, when the terminal is executing the CS service, the CS domain network side device to which the terminal belongs, such as MSC (Mobile Switchi...

Embodiment 2

[0038] This embodiment provides a method for switching services based on the first embodiment.

[0039] Such as figure 2 Shown is a schematic flow chart of the method for switching services according to this embodiment.

[0040] Step 201, receiving information about the CS service currently being executed by the terminal sent by the network side device in the CS domain to which the terminal belongs.

[0041] Specifically, the device for switching services receives the type identifier of the CS service currently being executed by the terminal sent by the MSC.

[0042] Step 202, when receiving a connection establishment request of a PS service with a higher priority than the CS service, according to the type identification of the PS service in the connection establishment request, obtain the network resources to be occupied by the PS service in the pre-acquired network resource occupation table value.

[0043] The apparatus for switching services may compare the priority of th...

Embodiment 3

[0069] This embodiment provides an apparatus for switching services, which is used to implement the method for switching services in Embodiment 1.

[0070] Such as image 3 Shown is a schematic structural diagram of the device for switching services according to this embodiment. The device for switching services includes a determination module 300 , a first judgment module 301 , an acquisition module 302 and a second judgment module 303 .

[0071] Among them, the determination module 300 is used to determine the network resources that the PS service needs to occupy when the terminal is performing the CS service and receives a connection establishment request of the PS service with a higher priority than the CS service; the first judgment module 301 is used to judge the current network resources. Whether the available network resources of the PS domain in the PS domain meet the network resources that the PS service determined by the determination module 300 needs to occupy, wh...

Abstract

The present invention provides a method and device for switching services. The method includes: when a terminal is executing a CS service and receives a connection establishment request of a PS service with a higher priority than the CS service, determining the network resources that the PS service needs to occupy; judging the current Whether the available network resources of the PS domain of the network meet the network resources occupied by PS services; when the judgment result is no, determine the candidate network capable of performing PS services; The network resources that the service needs to occupy. When the judgment result is yes, the terminal is switched to the alternative network to perform the PS service. According to the method and device for switching services of the present invention, by setting priorities for CS services and PS services, and by switching the terminal to an alternative network with sufficient network resources to perform PS services, PS services with higher priorities can be processed in time .

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for switching services. Background technique [0002] With the rapid development of communication technology, CS (Circuit Switched, circuit switching) services and PS (Packet Switch, packet switching) services are gradually increasing. [0003] The terminal is generally in the CS domain of the 3G network or 2G network when performing CS services, and the terminal can be in the PS domain of a network with PS service capabilities when performing PS services, generally LTE (Long Term Evolution, Long Term Evolution) network or some 3G networks . In the prior art, when the terminal falls back from the LTE network to the CS domain of the 2G or 3G network to perform CS services, if the terminal receives a PS service connection establishment request, it can only fall back to LTE after processing the current CS service The network handles PS services.
