IPC: H04W28/20
Filed: 1996-04-03
Abstract: A radio communication device (103), includes different modules (123, 125) providing access to different radio communication services. Upon adding or deleting modules (123, 125) to and from the radio communication unit (103), the radio communication system (100) reconfigures the channel providing radio communication services to the radio communication unit (103). Specifically, when a voice-only radio communication unit is communicating over a radio channel to a base site transceiver (101) the channel bandwidth requirements are minimal. Upon connection of the voice-only radio communication unit to a peripheral device (301, 401) providing simultaneous video, the radio communication unit (103) sends a signal to the base site transceiver (101) updating the service capability. In response thereto, the base site transceiver (101) modifies the records and adjusts the capabilities of the assigned channel in response to the received signal. Thereby delivering simultaneous video and voice to the radio communication device (103).
