Abstract

A communications device includes a first radio (106, 300) configured to support wireless communications with a second radio (104) using a plurality of communications modes. The device includes a switch element (118, 326) configured to cause the first radio to transmit when actuated. The device also includes a control element (306, 324) for detecting one or more actuations of the switch element and configured to select a one of the plurality of communications modes based on a sequence of the actuations of the switch element detected by the control element during a pre-defined time interval and to cause a wireless transmission from the first radio to the second radio according to the one of the plurality of communications modes.

6. The communications device of claim 5, wherein said short-range wireless communications link comprises a wireless communications link using protocols selected from the group consisting of Zigbee, Z-Word, Bluetooth, Wi-Fi, DECT, and CAT-IQ protocols.

7. The communications device of claim 5, wherein said control element is further configured to provide said wireless communications between said portable radio and said mobile radio using a direct long-range wireless communications link between said portable radio and said mobile radio when said sequence of said actuations corresponds to a second of said plurality of communications modes.

8. The communications device of claim 1, wherein at least said portable radio device is configured to provide at least one among an audio or a visual indicia of said selected one of said plurality of communications modes.

9. A method of operating a communications device comprising a portable radio which is part of a local radio system including a mobile radio, said mobile radio having a longer range capability as compared to said portable radio, and said portable radio configured to support wireless communications with a distant radio device using a plurality of communications modes responsive to actuation of a switch element communicatively coupled to said portable radio, the method comprising:

detecting one or more actuations of said switch element during a pre-defined time interval;

selecting a one of said plurality of communications modes based on a sequence of said actuations of said switch element during said pre-defined time interval; and

using said selected one of said plurality of communication modes to communicate with said distant radio device;

wherein said plurality of communication modes include communicating directly from said portable radio to said distant radio device and communicating indirectly from said portable radio to said distant radio device using an intermediate wireless transmission involving said mobile radio.

10. The method of claim 9, further comprising selecting each of said plurality of communications modes to correspond to a different one of a plurality of pre-defined actuation sequences, each of said plurality of pre-defined actuation sequences comprising at least one among a different number of said actuations during said pre-defined time interval and a different length of actuation time for at least one of said actuations during said pre-defined time interval.

11.
