EFFICIENT PERIODIC LOCATION REPORTING IN RADIO ACCESS NETWORK Russian patent published in 2010 - IPC H04W64/00 H04W4/02 

FIELD: physics; communication.

SUBSTANCE: invention relates to methods of providing position location services in a communication system. The result is achieved due to that, user equipment (UE) interacting with a radio access network (RAN) sends to a network object (for example MSC/SGSN) a request for periodically sending reports on location of UE to a client object. After approval of the request, the MSC/SGSN signals the RAN to initiate periodic transmission of reports on location of UE. RAN can send request the position location centre (for example SAS) to send assistance data to the UE. RAN can coordinate and control periodic transmission of location reports, or can handover control to the position location centre. For each location report transmission, UE sends location information to RAN (for example measurements taken by UE, or location evaluation by UE). SAS evaluates location if UE sends measurements. RAN then sends the location evaluation for UE to MSC/SGSN which sends the location evaluation to the client object.

EFFECT: more efficient provision for position location services, more specifically reduction of excess data traffic and duration of response time for sending location evaluation to the client object.
