Abstract: A dual autodiplexing antenna (300) redirects power flow (303) from an unloaded antenna to a loaded antenna, thereby improving communication performance under loaded conditions. The dual autodiplexing antenna (300) includes a first antenna (101) disposed at a first end (103) of a portable two-way communication device (100). A second antenna (102) is disposed at the distal end (104) of the portable two-way communication device (100). The first antenna (101) and second antenna (102) are coupled to a transceiver (107) by a first transmission line matching circuit (201) and a second transmission line matching circuit (202), respectively. In one embodiment, the first antenna (101) is configured to primarily operate in a first bandwidth, while the second antenna (102) is configured to primarily operate in a second bandwidth. When one of the first antenna (101) or second antenna (102) is loaded, power flow (303) is redirected to the lesser loaded antenna.

Abstract: The present invention provides a communication controller and a method for maintaining a communication connection during a cell reselection. The communication connection is maintained by changing between a first operating mode, such as a packet data mode, which does not support the maintenance of a communication connection throughout a cell reselection, and a second operating mode, such as a circuit switched mode, which does support maintenance of a communication connection during a handover. Use of a virtual mobile switching center in the base station subsystem facilitates the conversion and routing of circuit switched data, transmitted between the mobile subscriber and the base transceiver station, to the packet data network while in a circuit switched mode.
