Abstract: Walkie-talkies are a common means of coordinating activities at events but must be handed out, transferred as shifts and personnel in roles change, and collected. Further, walkie-talkies have a set range and the bigger the range the more expensive the walkie-talkie. Accordingly, it would be beneficial to provide individuals, enterprises, organizers, etc. with the ability to establish communications to individuals or group of individuals rapidly, with low complexity and management overhead, exploiting walkie-talkie style communications upon mobile devices connected to wireless networks over varying geographical areas without requiring distribution of walkie-talkies etc. as the mobile device is the user's own smartphone or cellphone. Further, it would be beneficial for such communications to be managed through a software application such that the user's virtual walkie-talkie automatically assigns channels etc. based upon the user's role, the event, their location etc.

Abstract: AT commands are used for controlling Mobile Termination (MT) functions and GSM/UMTS network services from a Terminal Equipment (TE) through Terminal Adaptor (TA). 3GPP introduces multiple backoff timers and barring to solve network congestion problem. However, a TE does not know the timer value and the barring status. In accordance with one novel aspect, a new AT command interface that can respond timer value and barring status to the TE is proposed. It reduces wasteful retries and saves power consumption of the TE. Through the new AT command interface, the TE can query backoff timer status. Via unsolicited result code (URC), the MT can detect backoff timer status change and report updated backoff timer status to the TE.
