Abstract:
PROBLEM TO BE SOLVED: To route an emergency call originated by a mobile station via a femto access point (FAP) in a wireless network and to locate the mobile station.SOLUTION: The emergency call may be routed to an appropriate emergency center on the basis of location information for the FAP, which may include a macro cell identity (ID) and/or a macro Mobile Switching Center (MSC) ID determined on the basis of the FAP location. The macro cell ID and the macro MSC ID may be assigned to the FAP and used to access a database which may store routing information for emergency centers versus cell IDs and MSC IDs. The location information for the FAP may include a location estimate for the FAP, and may be used to access a geographic database which may store routing information for emergency centers for different geographic areas.

PROBLEM TO BE SOLVED: To support a control plane solution for location services and positioning.SOLUTION: An Evolved Serving Mobile Location Center (E-SMLC) may communicate with a Mobility Management Entity (MME) to support location services and positioning for a UE. The E-SMLC may receive a location request from the MME, perform a positioning procedure with the UE in response to the location request, and send a location response to the MME after completing the positioning procedure. For a UE-assisted or UE-based positioning procedure, the E-SMLC may send a downlink positioning message to the UE via the MME and may receive an uplink positioning message from the UE via the MME.

PROBLEM TO BE SOLVED: To provide techniques for supporting location services with roaming.SOLUTION: A mobile station 110 communicates with a visited network 102a for a data session and receives a request for its location. The mobile station sends first information (e.g., SID and NID) indicative of its current network location to an H-MPC 160. The H-MPC 160 determines a serving mobile positioning center (S-MPC) 150 in the visited network based on the first information. The S-MPC 150 determines a serving position determining entity (S-PDE) 140 in the visited network based on the first information. The H-MPC 160 may receive an S-PDE address or a position estimate of the mobile station from the S-MPC and may forward this information to the mobile station. The mobile station 110 may communicate with the S-PDE 140 for positioning using the S-PDE address.
Abstract:
PROBLEM TO BE SOLVED: To allow at least one location related measurement for a terminal to be obtained and used to detect for a trigger event.SOLUTION: For an equidistance triggered service, a trigger event is declared if the distance traveled by the terminal exceeds a predefined distance. For a relative terminal to terminal triggered service, a trigger event is declared if the terminal is inside or outside, or enters or leaves a moving geographical target area defined by a reference terminal. For a velocity triggered service, a trigger event is declared if the maximum velocity of the terminal exceeds a predefined velocity. For a time-distance-velocity combination triggered service, a trigger event is declared on the basis of distance traveled by the terminal, velocity of the terminal, and time since the last report. For all services, a report is sent if a trigger event has occurred.

PROBLEM TO BE SOLVED: To control a wake-up mode of a wireless terminal when roaming from one wireless network to another wireless network.SOLUTION: A method for controlling a wireless terminal operating in a hibernation cycle alternating between a wake mode and a hibernation mode includes communicating with a first wireless network during a first waking period having a first duration, and with a second wireless network during a second waking period following the first waking period. The second waking period is extended to a second duration, greater than the first duration, responsively to detecting that the second wireless network is different from the first wireless network. Network information relating to the second wireless network is received during the second waking period.
