Embodiment Construction

[0033] Base stations of a wireless communication system are associated with coverage areas. When a mobile device moves outside the coverage area of ​​a base station, it may lose service from a wireless communication system with which it is associated via the base station. Lost services may include MBMS in some cases. To mitigate the chance of MBMS loss, the mobile device may broadcast an out-of-coverage status indicator or MBMS query in a peer discovery message. An in-coverage device (and possibly a mobile device) receiving an out-of-coverage status indicator or MBMS query may then determine whether it is capable of providing relay service (ie, acting as an MBMS relay) for MBMS desired by the out-of-coverage mobile device. Alternatively, the in-coverage mobile device can proactively transition to the MBMS relay state and for which it can provide at least one MBMS broadcast service announcement information for which the relay service is intended. Service announcement informat...

Abstract

Methods, systems, and devices are described for managing a multimedia broadcast multicast service (MBMS). In one configuration, service announcement information for at least one MBMS may be received. At least a subset of the service announcement information may be broadcast in a peer discovery signal. Content of the at least one MBMS may then be relayed to at least one mobile device operating outside a coverage area of a base station. In another configuration, an out-of-coverage status indicator or MBMS query may be broadcast in a first peer discovery signal, and a second peer discovery signal may be received from at least one MBMS relay device. The second peer discovery signal may include at least a subset of service announcement information for at least one MBMS.

Description

[0001] cross reference [0002] This patent application claims priority over U.S. Patent Application No. 13 / 954,739, filed July 30, 2013, by Wu et al., entitled "Managing a Multimedia Broadcast Multicast Service Using an MBMS Relay Device" and said U.S. patent application is assigned to the present assignee. Background technique [0003] A wireless communication network may include a number of base stations, Node Bs or eNode Bs (eNBs), which may support communication for a number of mobile devices or user equipments (UEs). A UE can communicate with a base station via downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station. [0004] In 3GPP cellular networks, broadcast and multicast services may be delivered via a delivery service called Multimedia Broadcast Multicast Service (MBMS). A Broadcast Multicast Service Cen...
