Mark E. Pecen - Palatine IL, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q007/20
H04Q007/38

US Classification:

4555521, 455436, 455437, 455440, 455442, 4554261, 4554221, 4555531, 370331, 370332, 370334, 370351, 370352, 370355, 370357

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.

Abstract:

A wireless transmitter () including an amplifier (), an automatic output controller () (AOC) having an output coupled to a control signal input.
