Abstract
A method and device for zero configuration direct fallback communication is provided. In one aspect a method comprises selecting a channel in a fallback radio band based on at least a portion of at least one system operating parameter for a primary radio band. The method further comprises switching to the selected channel in the fallback radio band. The method also comprises communicating over the selected channel in the fallback radio band.
Claims17
A method comprising:
- selecting a channel in a fallback radio band based on at least a portion of at least one system operating parameter for a primary radio band;
- determining at least a portion of a tracking area code (TAC);
- determining at least a portion of an International Mobile Subscriber Identity (IMSI) Block Number (IBN);
- combining the portion of the TAC and the portion of the IBN to create a Primary System Identifier (PSID);
- determining a provisioned talk group identifier (TGID);
- selecting the channel in the fallback radio band based on PSID*TGID;
- switching to the selected channel in the fallback radio band;
- and
- communicating over the selected channel in the fallback radio band.
A device comprising:
- a wireless transceiver;
- a processor;
- and
- a memory coupled to the processor containing a set of instructions thereon that when executed by the processor cause the processor to:
- select a channel in a fallback radio band based on at least a portion of at least one system operating parameter for a primary radio band;
- switch to the selected channel in the fallback radio band;
- and
- communicate over the selected channel in the fallback radio band.
- determine at least a portion of a tracking area code (TAC);
- determine at least a portion of an International Mobile Subscriber Identity (IMSI) Block Number (IBN);
- combine the portion of the TAC and the portion of the IBN to create a Primary System Identifier (PSID);
- determine a provisioned talk group identifier (TGID);
- select the channel in the fallback radio band based on PSID*TGID;
- switch to the selected channel in the fallback radio band;
- and
- communicate over the selected channel in the fallback radio band.
A non-transitory processor readable medium containing a set of instructions thereon that when executed by the processor cause the processor to:
- select a channel in a fallback radio band based on at least a portion of at least one system operating parameter for a primary radio band;
- determine at least a portion of a tracking area code (TAC);
- determine at least a portion of an International Mobile Subscriber Identity (IMSI) Block Number (IBN);
- combine the portions of the TAC and the IBN to create a Primary System Identifier (PSID);
- determine a provisioned talk group identifier (TGID);
- and
- select the channel in the fallback radio band based on the PSID*TGID;
- switch to the selected channel in the fallback radio band;
- and
- communicate over the selected channel in the fallback radio band.
