Efficient variable rate for broadcast/multicast service

摘要

A method, an apparatus, and a computer program product for wireless communication are provided in which at least one bit rate for allocating network resources from a broadcast-multicast service center (BM-SC) is received. The network resources are then allocated based on the at least one bit rate. Moreover, all evolved Node Bs (eNBs) in a broadcast/multicast area are informed of the network resource allocation. Additionally, the network resources are allocated for a session based on a first bit rate, wherein the first bit rate is greater than a guaranteed bit rate (GBR), and the network resource allocation is adjusted to a second bit rate based on the occurrence of an event, wherein the second bit rate is equal to GBR.

主权项

1. A method of wireless communication, comprising:
receiving at least one bit rate for allocating network resources from a network service center; allocating the network resources based on the at least one bit rate; informing all base stations in a broadcast/multicast area of the network resource allocation; receiving from at least one base station in the broadcast/multicast area status information indicating one or more of a change in an amount of MBMS data being received by the at least one base station via the allocated network resources or a change in a unicast load; and adjusting the network resource allocation based on the received status information,
wherein the at least one bit rate comprises a maximum bit rate (MBR) and a guaranteed bit rate (GBR), the method further comprising:determining an amount of available network resources for adjusting a network resource allocation of a session;determining an adjusted bit rate for transmitting data based on the adjusted network resource allocation; andinforming the network service center and all base stations of the adjusted bit rate.
