    摘要: The application discloses a method and apparatus for optimizing mobility of a mobile device in the wireless communication system. The method includes receiving (302) a plurality of mobility area descriptors from an external device, and configuring (304) the received plurality of mobility area descriptors in the mobile device. The method then determines (306) a current location of the mobile device (110), and selects (308) a mobility area descriptor among the plurality of mobility area descriptors based on the current location of the mobile device (110). The mobility area descriptor is associated with a geographical area (112) in the communication system. The method then finally optimizes the optimizing (310) the mobility of the mobile device (110) based on the selected mobility area descriptor.

    摘要: A receiving device in a trunked radio communications system retrieves a first frequency from a scan list and tunes to about the first frequency. If no control channel messages are decoded at the first frequency, then the receiving device tunes to about a second frequency. If no control channel messages are decoded at the second frequency, then the receiving device iterates through the scan list, until the last frequency in the scan list is reached, wherein the scan list comprises control channels for at least two band plans.

    摘要: A receiving device in a trunked radio communications system retrieves a first frequency, wherein the first frequency relates to a lowest frequency that the at least one repeater utilizes for transmission and tunes to about the first frequency. If no control channel messages are decoded at the first frequency, then the receiving device tunes to about a second frequency wherein the second frequency is a channel separation of 12.5 kHz from the first frequency. If no control channel messages are decoded at the second frequency, then the receiving device, iteratively increments the second frequency by the channel separation until the second frequency reaches an end of band frequency for the trunked radio communications system.
