Abstract: A broadcast service network (separate from a cellular network) includes broadcast service signal (BSS) nodes that broadcast signals to receivers of user equipment (UE). The BSS may provide broadcast service information to user equipment, such as the emergency notifications, even when the user equipment is out of range of the cellular network. Further, the broadcast service signals may provide information that improves the user equipment's search and access time for connecting to the cellular network (e.g., a cellular service station) and/or that assists the user equipment in locating a nearby region of cellular network coverage. In addition, the BSS may be wake-up signals configured to activate the receiver when the receiver is in a sleep or inactive mode. In some embodiments, the BSS may be pointer signals configured to direct the user equipment to a broadcast service channel to receive the broadcast service information.
