Abstract: A method for intelligent antenna configuration selection of a communication apparatus including an antenna module including a plurality of antennas and a plurality of radio modules sharing the antenna module includes individually determining a preferred antenna configuration of the antenna module by each radio module; determining an optimum antenna configuration according to the preferred antenna configurations; and controlling a configuration of the antennas based on the optimum antenna configuration. The optimum antenna configuration is determined for a radio module having a highest priority among the radio modules to have an optimum radio communication performance.

Abstract: A method for radio access technology, hereafter called RAT, change for a mobile device is disclosed. The method comprises whenever camping on a RAT, collecting cell information for at least one cell, falling back to a first RAT, and performing an offline procedure for moving to the camped RAT from the first RAT according to the collected cell information.

Abstract: A method of enhancing public land mobile network (PLMN) search for a mobile device in a wireless communication system is disclosed. The method comprises deriving a mobile country code (MCC) for identifying a visited country when the mobile device is switched on, powered up, into flight mode off, or coming back from no service area, and performing the PLMN search excluding for at least a PLMN, whose MCC is not the same as the derived MCC, according to a PLMN search list stored in the mobile device.

Abstract: An electronic device providing multiple operation modes is provided. The electronic device has a user interface displayed via a display device connected to the electronic device. The user interface displays icons corresponding to the multiple operation modes, receives a selection signal corresponding to a user-selected operation mode from an input device, and provides and displays corresponding function options to the user interface under the user-selected operation mode.
