Abstract: Methods and devices for transmission of communications during a silence interval are described. A base station (BS) provides timing data to an access terminal (AT) and AT uses timing data to synchronize with BS to carry our silence and non-silence intervals for an RF air interface. AT attempts to initiate communications by transmitting an access probe (AP) to BS during a non-silence interval. Other ATs may transmit communications to BS during non-silence interval. If BS acknowledges AP during non-silence interval, AT does not transmit during a subsequent silence interval. If AP was for an emergency communication and BS does not acknowledge AP sent during non-silence interval, AT transmits another AP during the subsequent silence interval to initiate emergency communication. If AP was not for emergency communication, AT does not transmit AP during the subsequent silence interval. The other ATs do not transmit communications to BS during the subsequent silence interval.

Abstract: A method, apparatus, and system for helping to manage advanced handoff to a coverage area based on correlation with a geographic region. A mobile station determines that it is in or approaching a defined geographic region, and the mobile station determines from correlation data that the geographic region is correlated with a particular cellular coverage area. The mobile station therefore requests handoff to the cellular coverage area and provides an advanced-handoff indication to cause the serving radio access network to maintain assignment of a radio connection in the coverage area longer than the network would normally, to help allow time for the mobile station to arrive at the coverage area and begin communicating on the radio connection with the network.

Abstract: When a UE has a first bearer with a gateway via a first base station and the UE engages in session setup signaling with a session server via that first bearer to set up a media session, the network may establish for the UE a second bearer via a second base station, and may the second bearer for communication of media content of the session while using the first bearer for communication control signaling for the session. In practice, the first base station could be a macro base station that operates on licensed frequency spectrum, while the second base station could be a small cell that operates on unlicensed frequency spectrum. The disclosed process can thereby help to offload communication of session content to be via the small cell instead of via the macro base station, while maintaining session control signaling to be via the macro base station.
