Abstract: Systems and methods are provided to facilitate direct wireless communication between mobile communication devices while avoiding the need for mobile communication devices to periodically scan for in-range devices and avoiding unwanted breaks in traffic caused by changes in the source and/or destination IP address of packets. Mobile communication devices periodically update their positions to a server, which can send a notification when a mobile communication device comes within range. Further, mobile communication devices can encapsulate packets with an IP address used for direct wireless communication to facilitate this direct wireless communication without disrupting traffic over a core network.

Abstract: A communication device and method for crowdsourcing of information from one or more communication devices. The crowdsourced information can be defined by one or more parameters defined in an operational framework. The operational framework can be, for example, an Access Network Discovery and Selection Function (ANDSF) framework. The operational framework can include, for example, positional and/or movement information of the communication device(s), a signal quality of a communication network, a visibility duration of a communication network, data rate information of a communication network, and/or quality of service (QoS) information of a communication network.

Abstract: Systems and methods are provided for using geo-fencing techniques to assist in detecting mobile communication devices that are close enough to support direct communication. A mobile communication device can periodically report its geo-fence area to a central server. The server can determine whether to ask the communication device to report more precise geographic information (e.g., GPS information) based on whether another communication device eligible for direct communication is within the same geo-fence area.
