Tail end MBMS bearer fault management

摘要

Systems and methods are provided for managing faults at the tail end of the user plane associated with an MBMS bearer. A fault detection time interval associated with the MBMS bearer can be defined and monitored. A fault can be detected in response to determining that the defined time interval has elapsed without receipt of a synchronization packet. Mechanisms for detecting, indicating, localizing and repairing MBMS bearer faults are described.

1. A method for fault management on a unidirectional user plane interface of a Multimedia Broadcast/Multicast Service (MBMS) bearer for point-to-multipoint delivery of MBMS traffic from a source node to at least one destination node, the method performed by a destination node and comprising:
defining a fault detection time interval associated with the MBMS bearer; starting a timer responsive to receiving a first synchronization packet from the source node over the unidirectional user plane interface; and detecting a fault on the unidirectional user plane interface responsive to determining that the timer exceeds the fault detection time interval and a subsequent synchronization packet has not been received during the fault detection time interval.
