A method, device and equipment for selecting a network according to a service used by a user

Abstract

The invention aims at providing a method, a device and equipment for selecting a network according to a service which is used by a user. The method comprises the following steps: when the service corresponding to an application function service unit is started by user equipment and the service comprises a preset type of data flow, sending conversion prompt information to an ANDSF (Access Network Discovery And Selection Function) service unit by the application function service unit through an Rx interface, wherein the conversion prompt information is used for prompting that a preset type of network is adopted when the preset type of data flow is transmitted; receiving the conversion prompt information and providing the information of new network selecting rules which are determined based on the conversion prompt information for the user equipment by the ANDSF service unit through the Rx interface; obtaining the service by the user equipment through the application function service unit according to the new network selecting rules. The method, the device and the equipment have the advantages that specific service can be used by the user equipment through the specific type of network, so that the network requirement of the user on the specific service can be met.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method, device and equipment for selecting a network according to services used by users. Background technique [0002] When performing an IP Multimedia Subsystem (IMS, IP Media Subsystem) session, when the user equipment is using certain key data streams, for example, conducting a video conference or downloading emails, it is necessary to maintain a stable network connection. For example, only use 3G network for connection, and do not want to switch to unstable Wi-Fi network. However, in the prior art, the Access Network Discovery Support Functions (ANDSF, Access Network Discovery Support Functions) server can only notify the user terminal that when the transmitted data stream is video, use or not use the Wi-Fi network to transmit the data flow. However, the ANDSF server in the prior art cannot further distinguish whether the currently transmitted video is ...

However, in the prior art, the Access Network Discovery Support Functions (ANDSF, Access Network Discovery Support Functions) server can only notify the user terminal that when the transmitted data stream is video, use or not use the Wi-Fi network to transmit the data flow

However, the ANDSF server in the prior art cannot further distinguish whether the currently transmitted video is an important video conference call or an unimportant movie video. Therefore, it is impossible to determine the adopted network based on the importance of the service.
