Operational parameter selection to avoid interference in a wireless communication system

摘要

A wireless communication device uses operational parameters stored in a capabilities list to control operation of the device. The device may also provide auxiliary services, such as reception of broadcast television signals and location detection using network assisted GPS. When auxiliary services are selected, the cellular operation may cause interference with the auxiliary services. The wireless communication device includes a reduced set of capabilities to control operation of the wireless communication device when an auxiliary service is requested. The particular set of reduced capabilities may depend on the specific type of auxiliary service that has been requested. Upon termination of the auxiliary services, the full capabilities list may be restored and the operation of the wireless communication device is thereafter controlled by the full set of operational capabilities.

主权项

1. A device comprising:
a transceiver that transmits and receives using a plurality of communication bands; an auxiliary receiver that communicates using a first communication band of the plurality of communication bands when the auxiliary receiver is selectively activated; a data storage structure that stores data indicating operational capabilities of the transceiver, the operational capabilities comprising a set of communication bands of the plurality of communication bands on which the transceiver communicates when the auxiliary receiver is selectively activated; and a controller that controls operation of the transceiver by selecting a communication band from the set of communication bands based on the data in the data storage structure when the auxiliary receiver is activated,
wherein the transceiver communicates using an initial communication band of the plurality of communication bands when the auxiliary receiver is not activated, andwherein the controller alters the initial communication band on which the transceiver communicates if the initial communication band is not one of the set of communication bands when the auxiliary receiver is activated.
