Abstract

The invention provides a solution for a new multimedia service manual for assisting the user terminal to receive the multimedia service. The multimedia service managing device inform the network server with the service identification of the multimedia service and the service address and the multimedia service managing device inform the multimedia service manual device with service identification of the multimedia service. The multimedia service manual device generates the multimedia service manual comprising the service identification. After the user terminal obtains the multimedia service manual, the invention inquires the corresponding service address according to the service identification in the network server and obtains the multimedia service according to the service address.

Description

technical field [0001] The present invention relates to a communication network, in particular to a method and a device for assisting a user terminal in receiving a multimedia service in the communication network, and a method and a device for a user terminal to receive a multimedia service.
