Application layer access channel congestion avoidance in group communications over broadcast/multicast services

摘要

The disclosure is directed to prioritizing call announce response in a broadcast/multicast communication system. An embodiment establishes a first priority for response based on assigning each user equipment (UE) a first random delay for response to a first call announce, responds to the first call announce using the first random delay, and determines a second priority for response to a subsequent call announce based on an elapsed time that each UE is present in a multicast area.

主权项

1. A method for prioritizing call announce response in a broadcast/multicast communication system comprising:
establishing a first priority for response based on assigning to a user equipment (UE) a first random delay for response to a first call announce; responding to the first call announce using the first random delay; and determining a second priority for response to a subsequent call announce based on an elapsed time that the UE is present in a multicast area wherein the elapsed time is determined by starting a timer when the UE enters the multicast area.
