Method and system for responding to a reception failure of a reverse link signal

摘要

A radio access network (RAN) allocates a resource, such as a forward traffic channel, to a mobile station that is engaged in a call. During the call, the RAN monitors a reverse link signal that is received from the mobile station. If the RAN detects a reception failure, such as the receipt of an errored frame in the reverse link signal, the RAN determines the power level that the mobile station used to transmit the reverse link signal when the reception failure occurred. If the mobile station was already transmitting at its maximum power level, the RAN may immediately release the resource. Otherwise, the RAN defines a test period that is sufficient for the mobile station to increase its transmit power to the maximum level. If the reception failure continues throughout the test period, the RAN may then release the resource.

主权项

1. A method for determining whether to release at least one resource that a radio access network (RAN) has allocated to a mobile station, said method comprising:
said RAN receiving a reverse link signal that is wirelessly transmitted by said mobile station; said RAN detecting a reception failure of said reverse link signal, said reception failure occurring at a first time; said RAN determining that said mobile station was transmitting said reverse link signal at a first transmit power level at said first time; said RAN defining a test period based on said first transmit power level, such that said test period is sufficient to allow said mobile station to increase its transmit power from said first transmit power level to a second transmit power level; said RAN determining whether said reception failure continues throughout said test period; and if said reception failure continues throughout said test period, said RAN releasing said at least one resource.
