Abstract: In a receiver having a plurality of demodulation elements, a method of assigning the plurality of demodulation element so a set of available signals. A first method emphasizes diversity of transmitting devices so that power control is optimal. A second method emphasizes the maximum signal strength available to produce aggregate maximum signal strength. Both methods control the number of reassignments so that excessive data is not lost during the reassignment process. The apparatus comprises the plurality of demodulation elements, at least one searcher element, and a controller.

Abstract: A method and apparatus for selecting a communication system in accordance with the geographic region in which the subscriber station is located is described. Upon successful acquisition, a system determination processor examines the received system identification information and compares it with system identification information stored in a universal system table to determine the geographical region of the identified communication system. The system determination processor then determines whether the acquired system is the most desirable system for use in the geographical region. If it is the most desirable system for use in the geographical region, the system determination processor selects the acquired system for providing service. If it is not the most desirable system for use in the geographical region, the subscriber station attempts to acquire a more desirable system using information from the universal system table.

Abstract: Microprocessor resource utilization by a searching process are controlled by determining a search window size, accessing a lookup table to determine an integration interval and a number of non-coherent passes, and commanding a searching process to execute a multipath search according to these parameters. The lookup table comprises a plurality of integration intervals and corresponding number of non-coherent passes indexed according to search window such that an execution duration of the search process remains nominally constant over a variety of search window sizes.

Abstract: The present invention is a novel and improved method for providing broadcast short message services (SMS) in a communication network. It is an objective of the present invention to provide a method and apparatus that insures the successful transmission of the broadcast message while minimizing the impact of providing the short messaging service on overall system capacity. Messages to be broadcast to a group of users are provided by broadcast page generator (20), to a braoadcast message buffer (24). The timing of the the message transmissions is controlled by a page transmit controller (34), and the message is modulated on to an appropriate channel by modulator (26).
