BROADCAST SERVICE (BC) IMPROVING METHOD, DEVICE AND SYSTEM

摘要

A method for improving Broadcast (BC) services includes the following steps: a Proxy-Call Session Control Function (P-CSCF) determines that a received service layer message is a BC service request; the P-CSCF sends a resource reservation instruction to a resource reservation processing entity, instructing the resource reservation processing entity to reserve shared resources. A device for improving BC services is also provided. By using the present invention, when a user initiates a BC service request, the P-CSCF sends an instruction to the resource reservation processing entity according to the BC service request of the user, instructing the resource reservation processing entity to reserve specific network resources. Because the user may watch only one channel at the same time, these resources may be shared by channels in the service package, thus saving network resources.
