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. The subscription management module manages service information of the purchase item based on the PurchaseItem identification. A device for implementing the above method is also disclosed in the present invention.
