Embodiment Construction

[0022] figure 1 One embodiment of a wireless communication network 10 is shown comprising a radio access network (RAN) portion 12 , a core network (CN) portion 14 communicatively coupled with one or more external networks 16 . Although not the only contemplated mechanism for detecting an actual or imminent alert condition, it is understood that Emergency Threat Warning System (ETWS) messages and / or other alert information may be received via the external network 16 .

[0023] The RAN 12 includes one or more cells 18, which may generally be referred to as a "service area 18," or a combination thereof, and corresponding base stations 20 that provide service in the cells 18. Wherein, the suffixes are used for clear distinction, and the service areas 18 may be referred to as service areas 18-1, 18-2, and so on. Similarly, base stations 20 may be referred to as base stations 20-1, 20-2, etc. if necessary for clear distinction. Each base station 20 supports communication services ...

Abstract

According to the teachings herein, a wireless device that is a candidate for operating in the cooperative positioning advantageously activates that mode in response to detecting a warning situation. In some embodiments, the detection and / or activation operations are autonomously undertaken by the wireless device. In other embodiments, the wireless communication network provides warning situation detection and / or control of the cooperative positioning mode. More generally, the wireless communication network maintains a database identifying those wireless devices within a given service area that are cooperative positioning mode candidates—e.g., the devices having D2D communication capability and operational configurations that allow such operation. By the network providing such information in advance of a warning situation, the candidate devices have the information needed to efficiently discover or otherwise identify other such candidates.

Description

technical field [0001] The present invention relates generally to wireless communication networks, and more particularly to cooperative positioning in such networks. Background technique [0002] A public land mobile network (PLMN) represents one example of the type of communication network that can play an important role in public safety and information dissemination. For example, Release 8 of the 3rd Generation Partnership Project (3GPP) specifications provides portions of the wireless system and associated system protocols, also known as the "Earthquake and Tsunami Warning System" or ETWS. ETWS address multiple hazard scenarios and operate to collect geological sensor or other hazard information and relay it to emergency points or other early warning system nodes for distribution to wireless devices. The ninth edition includes specifications for a Commercial Mobile Alert System (CMAS), which is designed to distribute alert signals to cellular users operating within cells...
