A communication device ( ) capable of transmitting information provides the means for regulating the temperature ( ) of one or more heat-sensitive modules or components ( ) of the communication device through the adaptive and dynamic control of the flow of transmissions by the communication device, thereby eliminating the need for stored thermal profiles of heat-sensitive modules of the communication device. In addition to the heat-sensitive module(s), the communication device has a multi-logic controller block ( ) and a transmission flow control block ( ). The multi-logic controller block ( ) receives the temperature of the heat-sensitive module ( ) and a first control clock ( ) and utilizes multi-value logic to generate a flow control signal having hysteresis ( ). The flow control block ( ) is coupled to the multi-logic controller block ( ) and the heat-sensitive module(s) ( ) and operates to generate a transmission control signal adapted to control transmission of information by the communication device in accordance with the flow control signal ( ) and a second control clock ( ) provided to the flow control block ( ).

Dynamic method and apparatus for controlling device temperature during continuous transmissions

A mobile communication device ( ) contains a memory ( ), a controller ( ) and transceiver components ( ). When an incoming call signal is received ( ), the controller compares the source identifier with various lists ( ) stored in the memory. If the source identifier is contained on a rejection list, the call is rejected. If the source identifier is contained on an acceptance list, the call is received normally, unless a do not disturb feature is active. The lists may be fixed or selectable. Selectable lists are configurable by the user of the mobile communication device, whereas fixed list types cannot be changed by the user of the mobile communication device.

Method and apparatus to locally block incoming selected calls

A communication device (,) has a serving and neighbor list (,) and a bandmap (,). Upon losing communication service (,) the device begins alternately scanning the serving and neighbor list (SNL) and subsections (,) of the bandmap. If an appropriate carrier is found while scanning the SNL, the device reconnects to the serving system. While scanning the subsections of the bandmap, the device creates and maintains a list (,) of suitable carriers. If no carriers are found corresponding to the SNL, a serving cell is selected from the list (,).

Method for recovering communication service

A communication device (100) contains a plurality of bandmaps in a memory (102). Upon powering up the device, the device first scans frequencies listed in a learned bandmap (104). If no suitable carrier signals are detected, the device scans the frequencies listed in a present regional bandmap (106), and this scan may be repeated several times. Upon failing to detect a suitable carrier at any of the frequencies listed in the present regional bandmap, the device alternates between scanning the present regional bandmap and segments of a world wide bandmap (108), which is a comprehensive list of all possible frequencies at which the device may operate. If a carrier is detected indicating the device is in a new region, the regional bandmap corresponding to the new region is set to be used as the present regional bandmap.

Method for registering a communication device for communication service

A subscriber unit handles incoming calls routed through an old server site while in the process of switching site affiliation to a new server site (500). The subscriber unit initiates the switching of site affiliation (510), and during the process, alternates between receiving communication from the new server site (520) and receiving communication from the old server site to monitor for an incoming call (530). When an incoming call routed through the old server site is detected (540), the subscriber unit aborts or suspends the switching process and accepts the incoming call through the old server site (551, 552).

Method of processing a call while switching site affiliation in a radio

A mobile station (100) maintains a preferred bandmap (106) and a fixed bandmap (104). Upon powering up the mobile station, the mobile station begins scanning frequencies listed in the preferred bandmap. The strength of each detected carrier signal is measured, and the mobile station connect to the serving cell having the strongest carrier signal. The preferred bandmap is maintained by placing the frequency of the most recently connected serving cell at the head of the list, and moving other frequencies down the list as other are added or rotated to the top of the list.
