    摘要: A communication device converts a bit stream to multiple symbols and provides encryption at a physical layer by shifting a phase of each symbol of the multiple symbols to produce multiple encrypted symbols. Each encrypted symbol of the multiple encrypted symbols is modulated with an orthogonal subcarrier to produce at least one modulated subcarrier and the at least one modulated subcarrier is then transmitted via a wireless link. On a receive side, a receiving communication device receives the transmitted, encrypted symbols and provides decryption at a physical layer by shifting a phase of each encrypted symbol in correspondence with the phase used to encrypt the symbol at the transmit side.

    摘要: During the course of a push-to-talk talkgroup wireless communication, decisions (21) are made regarding possible subsequent push-to-talk communication needs for the group. Based at least in part upon such decisions, a network location is identified (22) to provide talker arbitration support for this talkgroup. In one embodiment the identified network location can comprise a mobile station, such as a mobile station that comprises a member of the talkgroup. In a preferred embodiment, the talker arbitration capability is then assigned (24) to the identified network location.

    摘要: A communication system, upon receiving an instruction to transfer deferrable data, determines whether an air interface is congested and, when the air interface is congested, defers a transfer of the deferrable data or transfers the deferrable, lower priority data as higher priority data. When, during a transfer of deferrable data, the system determines that the air interface is congested, the system may terminate the call and save a state of a partially completed deferred data transfer. Subsequent to the termination of the call, the system establishes another data connection over the air interface and transfers any remaining, not yet transferred deferrable data. In order to discourage subscribers from transferring higher priority data as lower priority data, the system may further restrict a transfer of lower priority data to designated time periods while allowing a transfer of higher priority data during the designated time periods and other time periods.

    摘要: At least one Radio Frequency (RF) operating condition associated with a mobile station (102) is obtained. The RF operating condition is compared to an optimum value. When the RF operating condition is substantially different from the optimum value, the paging cycle is adjusted in order to conserve power in a battery associated with the mobile station (102).

    摘要: A method for paging a mobile station where the mobile station (208-212) may be in a dormant state is described. The method begins by sending a first paging message (302) in a first zone (214) of a given area to a selected mobile station wherein the first paging message is sent at the beginning of a paging interval (300). A base station (202-206) then receives a response to the paging message when the mobile station is in the first zone. When the response to the first paging message is not received, a second paging message (306) is sent in a second zone (216) of the given area. The second paging message is sent at a first offset (308) from the sending of the first paging message wherein this first offset occurs less than one paging interval after the sending of the first page message.

    摘要: A user initiates a group call from an initiating communication device to a plurality of group call recipients' communication devices. Then, a processor circuit determines a wait time for commencing communication of the group call according to a predetermined function. The predetermined function is based least in part on status information for at least a portion of the group call recipients wherein the status information includes a likelihood of participation in the group call. The status information used as part of the predetermined function may include various factors relevant to the likelihood of or expecting timing of a group call recipient's joining the call. Perceived delays can be further reduced by storing group call media prior to sending the media to or playing the media at a particular group call recipients' communication devices.

    摘要: An idle frame counter is not reset after retransmission of a data frame. Additionally, if a non-acknowledgment (NAK) is received for the last data frame sent, then no more idle frames are transmitted. Finally, an Idle Acknowledgment (ACK) is transmitted when an idle frame has been received with a sequence number equal to the sequence number of the next new data frame expected.

    摘要: One or more indicators as correspond to relative mobility of a wireless mobile station are monitored (21) to provide a resultant mobility indicator (26). Adjustment (24) of one or more inactivity temporal windows make use of this mobility indicator. Other criteria can be employed in a similar fashion, including information (25) regarding the operating capabilities of the mobile station and information (27) regarding communication system setup times. Pursuant to one embodiment, inactivity timers as used for a mobile station coincident with an active state of operation and/or a semi-dormant state of operation are selectively and dynamically extended and/or shortened as based, at least in part, upon such criterion.
