mbms bearer fault management method, network node and fault manager

Abstract

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

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to prior US Provisional Patent Application No. 61 / 951,472, entitled "Tail End MBMS Bearer Fault Management," filed March 11, 2014, the contents of which are incorporated herein by reference. technical field [0003] This disclosure relates generally to Multimedia Broadcast / Multicast Services (MBMS), and in particular, this disclosure relates to systems and methods for detecting, indicating, locating and repairing MBMS bearer failures. Background technique [0004] Multimedia Broadcast / Multicast Service (MBMS) is a broadcast service provided via cellular networks including Wideband Code Division Multiple Access (WCDMA) and Long Term Evolution (LTE). MBMS is a point-to-multipoint or multicast service in which data is transmitted from a single source entity to multiple destination recipients. MBMS services can be used for file downloads and streaming services, such as mobil...

Use of such BFD capabilities is not available with IP multicast communication over many routers

Also, BFD does not detect many UP issues such as, as non-limiting examples, multicast channel status and RPF failures that may affect end-to-end MBMS UP bearers, including but not limited to MBMS services within MBMS-GW or eNB respectively internal fault at the head end or tail end of
