1. A wireless access network to provide multicast broadcast service (MBS) comprising:
- a multicast broadcast service controller (MBSC) to create an MBS zone comprising a plurality of base stations by establishing time and frequency parameters for simultaneous multicast downlink transmissions from the plurality of base stations to mobile stations within the MBS zone; and
an MBS agent (MBSA) within each of the base stations to synchronously transmit identical MBS regions within downlink subframes, the identical MBS regions including multicast data identified by multicast connection identifiers (CIDs),wherein the MBSC adds a shim layer to multicast packets received from content servers, the shim layer to include a multicast CID, a current timestamp, a next timestamp, and a packet sequence number for each of the multicast packets.

Abstract
Embodiments of a wireless access network and method for providing multicast broadcast services within multicast broadcast service zones are generally described herein. Other embodiments may be described and claimed. In some embodiments, a multicast broadcast service controller within a network gateway creates a multicast broadcast service zone of base stations by establishing time and frequency parameters for simultaneous multicast downlink transmissions to mobile stations within the MBS zone.

11. A method of providing multicast broadcast service (MBS) in a wireless access network comprising:
-
creating, by a multicast broadcast service controller (MBSC), an MBS zone comprising a plurality of base stations by establishing time and frequency parameters for simultaneous multicast downlink transmissions to mobile stations within the MBS zone; synchronously transmitting, by a multicast broadcast service agent (MBSA) within each of the base stations, identical MBS regions within downlink subframes by the base stations of the MBS zone, the identical MBS regions including multicast data identified by multicast connection identifiers (CIDs); and adding, by the MBSC, a shim layer to multicast packets received from content servers, the shim layer to include a multicast CID, a current timestamp, a next timestamp, and a packet sequence number for each of the multicast packets. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of internet-protocol (IP) multicasting in a wireless access network comprising:
-
receiving, at a serving base station, a request from a mobile station to join an existing multicast session; requesting authorization from an authentication authorization accounting server with a policy function to provide authorization for the mobile station to receive multicast broadcast services (MBS); transmitting from the serving base station, a dynamic service addition request to the mobile station, the dynamic service addition request including a multicast CID and a multicast zone identifier; and transmitting IP multicast data encapsulated with the multicast CID. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
