Abstract: The present invention relates to Mobile Broadcast Multicast technologies, and discloses a method for subscribing a purchase item in Mobile Broadcast Multicast Service, so that the subscription operation and update operation of the purchase item in BCAST are simplified, and the utilization of system resources is improved. In the present invention, a subscription management module generates a PurchaseItem identification, and sends this identification to a service distribution and adaptation module. Therefore, the PurchaseItem identification may be included in a PurchaseItem fragment sent to a user terminal from the service distribution and adaptation module. And, the function of identifying the purchase item is separated from the PurchaseItem fragment identification. Through sending a service request including the PurchaseItem identification to the subscription management module by the user terminal, the subscription of the purchase item is accomplished.

Abstract: A method and a system for distributing a mobile broadcast service are provided. The method includes: adding header information into broadcast service contents, the header information comprising integrality information and version information of a service packet containing the broadcast service contents; distributing the service packet to a user terminal; updating or accepting, by the user terminal, its own service data by use of the service packet in accordance with the integrality information and version information of the service packet. The method and the system according to the embodiments in the present invention may bring about higher transmission efficiency of data packet.

Abstract: A method for managing communication terminal device includes sending a device management command which includes a control instruction for an activity state of a designated function, to a terminal; and performing, by the terminal, an operation on the activity state of the designated function according to the control instruction. The invention further provides a corresponding communication terminal and system. Using the present invention may avoid running the service client-end function in the communication terminal all the time, saving electric energy or terminal resources.
