Abstract:
A method for obtaining service when in a no-coverage area (11) of a radiotelephone communication system (18) includes a first step of storing (32) information regarding a last known available communication system. This can be accomplished through the communication system (18) when loss of service is imminent or through independent means after service is lost. A next step includes reporting (34) the information about the last known available communication system (12) to a user of the radiotelephone (10). A next step includes using (36) the information to obtain service from the last known available communication system (12). For example, a user could use timing information to backtrack their steps or use location information to obtain service.
Abstract:
In certain embodiments of a cognitive radio (100), a method of establishing operational policies, involves determining that a new policy decision should be made; requesting a policy decision from an authority having more computing power than the cognitive radio; receiving the policy decision from the authority; and implementing the policy decision in the cognitive radio. Other embodiments may incorporate more, fewer or other elements.
Abstract:
In certain embodiments, a method for managing operational parameters of a cognitive radio device to minimize non-compliance with a regulatory policy involves sensing a change in an operational condition that will affect compliance with a current operational policy; estimating a time at which the current operational policy will become invalid; selecting a method for determining how to update the current operational policy; and updating the current operational policy of the cognitive radio device. Other embodiments may incorporate more, fewer or other elements.
