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 serving base station (SBS) that provides service to a UE device can receive or determine admission capacity of a neighbor base station (NBS). The SBS can determine a reporting interval based on the admission capacity and provide the UE device with the reporting interval. Upon determining that handover from the SBS to the NBS may be necessary, the UE device can responsively start transmitting measurement data regarding the NBS to the SBS. Transmission of the measurement data can occur at intervals that equal the reporting interval. The value of the reporting interval can be conditioned on the admission capacity of the NBS. As the capacity for admitting more UE devices decreases, the likelihood of the UE device handing over to the NBS may decrease. Increasing the reporting interval for reporting measurement data regarding the NBS can reduce loading of the reverse-links to the SBS.

Abstract: A method and corresponding apparatus to help avoid a scenario where a wireless communication device registers within a first radio access network (RAN) but then fails to transition from that first RAN to engage in a communication on a second RAN. When a WCD detects coverage of the first RAN, the WCD may condition its registration with the first RAN on the WCD also being within coverage of the second RAN.

Abstract: During an initial part of a communication session, a transmitting node transmits digital data over a first air interface channel to a receiving node, using a first data rate and a first level of repetition. A degradation in quality of the communication session is detected. During a subsequent part of the communication session, the transmitting node transmits digital data over the first air interface channel as before but also transmits the digital data over a second air interface channel, using a second data rate and a second level of repetition. The second data rate is higher than the first data rate, and the second level of repetition is higher than the first level of repetition. Thus, during a given transmission period, the transmitting node may transmit a voice frame once over the first air interface channel and N times over the second air interface channel.

Abstract: A method and apparatus to help minimize tuneaway time of a user equipment device (UE), by dynamically scheduling when the UE should tune away to scan for coverage of a particular wireless communication system, such as a time division duplex (TDD) system for instance. The UE may receive downlink transmissions from a TDD system and determining a downlink transmission schedule of the TDD system based on when those downlink transmissions occurred. Further, the UE may then use the determined downlink transmission schedule as a basis to schedule tuneaway of the UE from a serving system to scan for coverage of the TDD system.

Abstract: A wireless communication device (WCD) may be configured to engage in a wireless data communication session of a given type. The WCD may determine the given type of wireless data communication session, and based on the given type, the WCD may set itself to operate in a current operational state selected from a group consisting of a first and second operational state. While engaged in the wireless data communication session, the WCD may wirelessly receive a voice call setup request from a radio access network (RAN) seeking to set up a voice call to the WCD over an air-interface protocol. In accordance with the current operational state, the WCD may make a decision of whether to accept or reject the voice call request so as to interrupt or not interrupt the wireless data communication session.

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: A method and system to help control CoMP service in a V-RAN arrangement. The load on a cell site's fronthaul network interface between the cell site's RRH and the cell site's BBU is determined. And in response to detecting that the fronthaul load is threshold high, a limit will be imposed on application of CoMP service involving the cell site. For example, in response to detecting that the cell site's fronthaul network interface is threshold highly loaded, (i) the cell site could be made to use decentralized joint processing rather than centralized joint processing, (ii) a lower coverage strength threshold could be imposed as a basis to trigger CoMP service involving the cell site, and/or (iii) the quantity of uplink communication that is subject to CoMP service involving the cell site could be limited.

Abstract: An exemplary method involves a user equipment (UE) receiving a communication-origination request to initiate a communication with a given counterpart. In response, the UE: (a) uses historical communication data for one or more previous communications as a basis for evaluating whether the UE is likely to be assigned a particular codec, from a plurality of possible codecs, for communication with the given counterpart; (b) based on results of the evaluation, determines a respective setting for each of one or more access parameters affecting a likelihood of successfully establishing the communication with the given counterpart; and (c) performs the communication-origination process according to the determined settings for the one or more access parameters, to initiate the requested communication with the given counterpart.
