1. A multicast and broadcast service (MBS) system, comprising:
- an MBS server;
a base station, wherein the system is defined with at least one MBS zone, and each of the at least one MBS zone comprises at least one base station;
an access service network (ASN) gateway including an MBS data path function (DPF) adapted to establish, modify, or delete an MBS bearer between the MBS DPF and the base station, and the MBS bearer is adapted to transmit an MBS packet to the base station;
at least one MBS proxy function entity adapted to manage the at least one MBS zone, and each of the at least one MBS zone is managed by one of the at least one MBS proxy function entity.

Abstract
An MBS system, an MBS zone partitioning method, and a method for implementing MBS in a wireless network are disclosed. In the present invention, each MBS zone is managed by an MBS proxy function entity as a signaling plane entity, and the MBS proxy function entity allocates, manages and maintains the resource within the MBS zone. An ASN gateway containing an MBS DPF is adapted to establish, modify, or delete an MBS bear between the MBS DPF and a base station. An MBS agent contained in the base station is adapted to establish the MBS bearer and classifies and distributes MBS packets cooperating with the MBS proxy function entity and the MBS DPF.

18. A multicast and broadcast service (MBS) zone partitioning method, comprising:
-
allocating an MBS zone identifier to a base station set having at least one base station; and providing an MBS in the base station set with the MBS zone identifier. - View Dependent Claims (19, 20, 21)

22. A method for implementing a multicast and broadcast service (MBS) in a wireless network, comprising:
-
interacting messages between an MBS server, an MBS proxy comprising an MBS proxy function entity and an MBS data path function (DPF), and an MBS agent when the MBS server determines that the MBS is required to be implemented, so as to a reserve network side resource for the MBS; using the reserved network side resource to send an MBS program provided by an MBS content provider to a subscriber terminal through one of the following combinations; the MBS server, the MBS proxy, and the MBS agent, and the MBS proxy and the MBS agent. - View Dependent Claims (23, 24, 25, 26)
