Abstract: A method for charging for a service is provided. The method includes: receiving, by a data service management device, submitted current communication service scenario information of a user; searching, by the data service management device, for priority information of charging in an account of the user, in a mapping relation between a communication service scenario and a charging priority of the account, according to the received current communication service scenario information of the user; pricing, in the account of the user according to the found priority information, and submitting a priced result to an intelligence network; and charging, by the intelligence network, the account of the user sequentially according to the submitted priced result. A device and a system for charging for a service, and a service management device are also provided.

Abstract: A method for user equipment acquiring a multicast program address includes: receiving, via a Short Massage Service Center (SMSC), an updating program bookmark message containing a multicast program address from an Over The Air (OTA); acquiring the multicast program address from the updating program bookmark message. The present invention also provides a system and an apparatus for user equipment to acquire a multicast program address. With the solution of the present invention, the UE may acquire the multicast program address without network connecting.
