20100093389 | RESPONDING TO A PAGING REQUEST FROM A GSM NETWORK BY SETTING UP THE CALL THROUGH A UMTS NETWORK - A mobile terminal includes a GSM transceiver, a UMTS transceiver, and a controller. The GSM transceiver communicates via a GSM radio communication interface. The UMTS transceiver communicates via a UMTS radio communication interface. The controller is configured to select and register with a UMTS cell provided by a UMTS radio network controller, to store UMTS cell data defining a snapshot of communication characteristics of the selected UMTS cell, to respond to having registered with the selected UMTS cell by monitoring a GSM control channel via the GSM transceiver for an incoming paging request transmitted by a GSM base station controller, and to respond to receipt of the paging request from the GSM base station controller by using the stored UMTS cell data to assist in setting up a corresponding call via the UMTS transceiver and the selected UMTS cell through the UMTS radio network controller and a UMTS core network. | 04-15-2010 |
20100105425 | VARIABLE IMPEDANCE MATCHING NETWORK AND METHOD FOR THE SAME - An improved variable matching network for use in a multi-band, multi-mode communications device provides dynamic, fine-tune impedance matching based on current operational conditions associated with a given signal.
