  • Patent number: 8447297
    Abstract: Apparatus (48), and an associated method, for facilitating effectuation of control over when a mobile node (12) operable in a communication system (10) generates control signaling pursuant to a control procedure (62), such as a network search and selection procedure (64) or a registration procedure (66). A determiner (52) determines whether prior-sent control signals appear to have been successfully delivered to the network. If not, a selector (54) selects whether to increase a wait period prior to commencement of a subsequent control procedure, such as another network searching and selection procedure.
    Type: Grant

  • Patent number: 8374321
    Abstract: This relates to a method for determining a receive bit rate over a data link. The method includes setting a receive bit rate to an initial bit rate. A bit pattern over the data link is detected using the initial bit rate. A determination is made as to whether the detected bit pattern matches one of a plurality of known bit patterns corresponding to fractional bit rates. If the detected bit pattern does not match one of the plurality of known bit patterns, then a determination is made as to whether the received data includes a framing error. If it does, then the receive bit rate is lowered to a low detection bit rate that is lower than the fractional bit rates corresponding to the plurality of known bit patterns.

  • Patent number: 8199704
    Abstract: A method of scanning for an encoded signal, such as a GSM encoded signal, in a frequency band is disclosed herein. The disclosed method provides either more rapid acquisition of a signal, or increased battery life for mobile devices in regions without service. A corresponding mobile device that performs the method is also disclosed.

  • Patent number: 7738639
    Abstract: A method and system of matching a bit rate to a transmit bit rate used to transmit data on a data link are disclosed. A bit pattern in data received on the data link is detected using a bit rate. Where the detected bit pattern comprises one of a plurality of expected bit patterns, the bit rate is adjusted to an adjusted bit rate based on the detected bit pattern. In one embodiment, the adjusted bit rate is used for communications on the data link when a confirmation bit pattern is received within a predetermined time after the data is received.
