WIRELESS LOCAL COMMUNICATION SYSTEMS AND METHODS FROM WAN FALLBACK

摘要

A method, a mobile device, and a wireless system provide wireless local communication systems and methods from Wide Area Network (WAN) fallback allowing proximate users to maintain connectivity therebetween while WAN connectivity is lost. The wireless local communication systems and methods leverage access point credentials for the WAN to set up local wireless communication amongst the mobile devices when WAN connectivity is lost or when commanded to do so. Local mobile device users can maintain communication such as in a talkgroup while WAN connectivity is disrupted or undesired. The systems and methods include an algorithm where a first mobile device identifies the loss of WAN connectivity and becomes a WAN access point for other proximate mobile devices which share common preconfigured credentials. Subsequent mobile devices which detect the loss of WAN connectivity can associate with the AP thereby maintaining local communication using local wireless connectivity techniques.

主权项

1. A method, comprising:
performing, by a mobile device, one of determining that communication with a wide area network (WAN) access point is unsuccessful or receiving an explicit command; and taking a role of the WAN access point by the mobile device when the communication is unsuccessful or based on the explicit command; wherein the mobile device uses access point credentials that are based on at least a group identifier used with the WAN access point.
