Quality of service control in a multicast transmission

摘要

A network entity may dynamically control Quality-of-Service (QoS) for a multicast transmission in a wireless communications system, by initiating a multicast transmission having an initial QoS, and later during the multicast transmission, generating an updated QoS for the multicast transmission. The network entity may generate the updated QoS in response to a network load factor for a multicast area aggregated from base stations in the area. The network load factor may indicate a measure of aggregate available bandwidth in the multicast area. The network entity may provide the updated QoS to mobile entities receiving the multicast transmission, which may process a subsequent portion of multicast content according to the updated QoS.

1. A method for dynamically controlling Quality-of-Service (QoS) for a multicast transmission from a network entity of a wireless communications system (WCS), the method comprising:
initiating a multicast transmission session having an initial QoS and broadcast in a multicast area comprising multiple cells; generating an updated QoS for the multicast transmission session, in response to a network load factor for the multicast area, prior to termination of the multicast transmission session; and announcing that the updated QoS will take effect at a specified frame boundary or time during the multicast transmission session, wherein the network load factor comprises a measure of aggregate available bandwidth determined by processing bandwidth information from base stations in the multicast area.
