Abstract
A broadcast management message includes MBS Zone Neighbor information to associate different MBS Zones which transmit the same MBS contents over a single frequency or a different frequency. An MBS Zone Service Group contains a group of MBS Zones that transmit the same MBS content over the same frequency or at different frequencies. All the MBS Zones that belong to the same MBS Zone Service Group may have the same MBS Zone Service Group Identifier (ID).
Claims57
A method for providing a multicast and broadcast service (MBS) in a wireless network, the method comprising:
- connecting a first MBS MAC connection between a mobile station (MS) and a first base station (BS) in a first MBS Zone identified by a first MBS Zone ID;
- the MS receiving MBS Zone neighbor information associating the first MBS Zone with a second MBS Zone identified by a second MBS Zone ID, wherein the first MBS Zone and the second MBS Zone comprise the same MBS content;
- selecting a second base station (BS) in the second MBS zone;
- and
- connecting a second MBS MAC connection between the MS and the second BS.
The method of claim of 5, wherein the second MBS MAC connection is associated with the first MCID.
The method of claim of 5, wherein the MBS Zone neighbor information comprises a second MCID.
The method of claim of 7, wherein the second MBS MAC connection is associated with the second MCID.
The method of claim of 4, wherein the first MBS Zone and the second MBS Zone comprise the same security association.
The method of claim of 4, wherein the MBS Zone neighbor information comprises a security association associated with the second MBS Zone.
A method for providing a multicast and broadcast service (MBS) in a wireless network, the method comprising:
- providing a first MBS Zone comprising at least a first Base Station (BS), the first MBS Zone being identified by a first MBS Zone ID;
- providing a second MBS Zone comprising at least a second Base Station (BS), the second MBS Zone being identified by a second MBS Zone ID, wherein the first MBS Zone and the second MBS Zone comprise the same MBS content;
- and
- transmitting MBS Zone neighbor information associating the first MBS Zone with the second MBS Zone.
The method of claim of 27, wherein the MBS Zone neighbor information comprises a security association.
A method for providing a multicast and broadcast service (MBS) in a wireless network, the method comprising:
- connecting a first MBS MAC connection between a mobile station (MS) and a first base station (BS) in a first MBS Zone identified by a first MBS Zone ID, the first MBS Zone and a second BS Zone identified by a second MBS Zone ID comprise the same MBS content and belong to an MBS Zone Service Group identified with an MBS Zone Service Group ID;
- the MS receiving the MBS Zone Service Group ID in a broadcast management message;
- selecting a second base station (BS) in the second MBS zone;
- the MS determining the second MBS Zone ID;
- and
- connecting a second MBS MAC connection between the MS and the second BS.
The method of claim of 26, wherein the first MBS MAC connection and the second MBS MAC connection support the same set of logical channels.
The method of claim of 26, wherein the first MBS Zone and the second MBS Zone comprise the same security association.
A method for providing a multicast and broadcast service (MBS) in a wireless network, the method comprising:
- providing a first MBS Zone comprising at least a first Base Station (BS), the first MBS Zone being identified by a first MBS Zone ID;
- providing a second MBS Zone comprising at least a second Base Station (BS), the second MBS Zone being identified by a second MBS Zone ID, wherein the first MBS Zone and the second MBS Zone comprise the same MBS content and belong to an MBS Zone Service Group identified with an MBS Zone Service Group ID;
- and
- transmitting the MBS Zone Service Group ID in a broadcast management message.
