摘要： A method for controlling diversity receivers in a wireless communication device includes the steps of: determining if the wireless communication device is experiencing poor coverage (220), using a first receiver and a second receiver for diversity (230) if the wireless communication device is experiencing poor coverage, and using the second receiver for scanning (240) if the wireless communication device is not experiencing poor coverage. Thus, diversity can be used when needed to improve reception. Both receivers, however, can be used in a non-diversity mode to reduce current drain or to speed up channel acquisition when coverage is not poor.

摘要： A method and system for selecting a communication network by a wireless communication device (106) includes receiving (310) an identification parameter at the wireless communication device from a communication network which identifies the communication network. Next, the method compares (312) the identification parameter with a list at the wireless communication device to determine (314) service information. The service information identifies the services supported by the communication network. The method further includes comparing (316) the service information with a service-related datum at the wireless communication device that indicates the services desired by the wireless communication device. Lastly, the method includes selecting (318) the communication network for accessing a requested service if the service information matches the service-related datum.

摘要： A communication device performs a method for detecting presence of a jamming signal. The method includes retrieving a scan list comprising multiple radio channels within a first frequency range of operation of the communication device. The method further includes scanning at least a subset of the channels on the scan list to determine, for each scanned channel, whether energy that exceeds an energy threshold is detected on the scanned channel. Moreover, the method includes determining a first quantitative measure based on a first plurality scanned channels having energy that exceeds the energy threshold, and comparing the first quantitative measure to at least a first jamming signal detection threshold. Additionally, the method includes indicating, on the communication device, presence of a jamming signal when the first quantitative measure satisfies the at least a first jamming signal detection threshold.

摘要： A method (200) in a CDMA terminal device for acquiring a system identified in an enhanced preferred roaming list (enhanced PRL), with at least one entry containing a mobile country code, includes the steps of obtaining (210) system identifiers from SYNCH channels on a scan list, determining (220) if the system identifiers match entries on the enhanced PRL, and inserting (226) channel information items on a first list if the system identifiers do not match entries on the enhanced PRL. If all channels on the scan list have been scanned without any system identifiers matching entries on the enhanced PRL, the method obtains (246) mobile country codes using channel information items from the first list, determines (250) if the mobile country codes match entries on the enhanced PRL, and camps (283) on a system if its mobile country code matches an entry on the enhanced PRL.

摘要： A method and system for maintaining registration information for multiple communication areas within a network is provided. For a particular mobile subscriber, information associated with at least some prior registrations are retained, and in some instances are re-used upon re-entry into a communication area in which the mobile subscriber was previously located. The retention of registration information for multiple communication areas is managed as the default, without requiring additional signaling associated with each registration.
