Method and apparatus for propagating public safety multicast and broadcast services among public safety personnel

摘要

Public safety user equipment (PS UE) that establishes a first wireless communication channel over a primary network to at least one multimedia multicast or broadcast service management entity and establishes one or more alternative wireless communication channels over one or more alternative networks (310). The public safety user equipment receives at least one multimedia multicast or broadcast service message over the first wireless communication channel (320), Then, the PS UE extracts data contained in the multimedia multicast or broadcast service message and storing the data in a local cache (330). The PS UE receives a cache request from the one or more user equipment over one or more alternative wireless communication channels (340) and then the PS UE transmits the stored data to the one or more PS user equipment (350).
