Abstract: A cell search for recovering service provided to a mobile communication terminal that has a first communication subsystem capable of accessing a first access network and a second communication subsystem capable of accessing a second access network is performed with reduced power consumption. If the first communication subsystem looses coverage, the cell search is performed using a list of neighboring cells provided by the second communication subsystem and covered by other access network, rather than performing cell search in a full-band searching manner. If the list of cells remains unchanged and the first communication subsystem cannot successfully camp on a cell after a first number of attempts, a time interval for cell search is increased, so as to avoid meaningless search under poor network quality, and thus to reduce the power consumption of the mobile communication terminal.

Abstract: The present subject matter discloses a method for antenna activity detection in multi-antenna communication devices. In one embodiment, the method comprises computing a received signal strength indicator (RSSI) value for each of a plurality of antennas based on a sampled data associated with each of the antennas. The RSSI values may then be analyzed to identify an antenna having a highest RSSI value as a primary antenna and one or more antennas having the RSSI value less than the highest RSSI value as auxiliary antennas. Further, an RSSI difference for each of the auxiliary antennas is calculated and compared with a first threshold value to ascertain one or more potentially inactive antennas from among the auxiliary antennas. The potentially inactive antennas may then be further analyzed to identify one or more inactive antennas based at least in part on the RSSI value.
