Abstract
A cellular radio communications system includes a cellular radio network for establishing communications, via a communications link such as a voice channel, with a cellular terminal and open communications link maintaining means for maintaining the communications link in an open state for a predetermined time period following termination of the communications with the cellular terminal. Accordingly, the user of the cellular terminal may continue to access the cellular radio network within the predetermined time period via the open communications link or voice channel. The cellular radio communications system may also include a feature node for providing predetermined functions to the cellular terminals associated with the cellular radio network. The open communications link maintaining means typically includes a timer and related controller for initiating and monitoring the predetermined time period. In addition, either the cellular terminals, themselves, or a feature node associated with the cellular radio network may include the communications link maintaining means.
