  • Patent number: 8873660
    Abstract: A method and apparatus controls diversity reception in a wireless communication device. By determining a value based on a number of active set pilot signals received from a set of base stations, the wireless communication device dynamically enables or disables diversity reception. Diversity reception can be controlled by adjusting a diversity threshold based on the determined value. A channel quality indicator of a channel is measured and compared against the adjusted diversity threshold. The diversity reception mode is then enabled or disabled based on the comparison. For example, if the number of active pilot signals is above a predetermined value, indicating “good” coverage, the diversity threshold is decreased. The measured channel quality indicator is compared against the adjusted threshold, and diversity reception is enabled when the channel quality indicator is less than the decreased diversity threshold.

  • Patent number: 7778652
    Abstract: A system (100) includes a mobile station (125) to initiate an outgoing communication anywhere in a coverage area (115). A base station (110) and a radio access network (105) provide wireless service to the mobile station (125). The mobile station is paged in the sectors overlapping with only the clean zone. The mobile station (125) is paged in the sectors overlapping with the hot zone if the mobile station has predetermined trusted characteristics, or the mobile station is located within a clean zone of sectors overlapping with the hot zone, and an incoming communication for the mobile station originates from a predetermined trusted source. Existing calls to the mobile station are terminated in response to the existing call exceeding a predetermined threshold time limit, or a detected amount of voice activity in the existing call being below a predetermined threshold level.

  • Patent number: 7697451
    Abstract: An embodiment generally relates to a method of maximizing network efficiency. The method includes determining a state of a connect attempt from a network and re-transmitting a connect attempt response message to the network in response to the network's connect attempt being in a pending state after an attempt to setup a connection to the network fails.

  • Publication number: 20100056157
    Abstract: A method and apparatus for handover of a mobile station from a serving system to a target system, where a network of the serving system is different from a network of the target system is disclosed. The method includes measuring a Link Quality (LQ) of the target system and adjusting a nominal handoff threshold based on the Link Quality measurement to produce an adjusted handoff threshold. The method further includes, determining whether a handoff of the mobile station from the serving system to the target system should occur, based on the adjusted handoff threshold.
