Abstract: In an aspect, a generic positioning protocol (GPP) may be used to support satellite-based positioning methods and terrestrial-based positioning methods for different access types. A terminal may exchange a first GPP message with first information for a positioning method and an access type supported by GPP. The terminal may exchange a second GPP message with second information for the positioning method and the access type. Each GPP message may include at least one position element, and each position element may be for a specific positioning method. The terminal may obtain a position estimate for itself based on the second information. In another aspect, positioning may be performed based on measurements for cells of different wireless access types. In yet another aspect, received transmission times may be transformed to converted times based on common timing, which may be applicable for multiple wireless access types.

Abstract: Techniques for supporting positioning for terminals in a wireless network are described. In an aspect, positioning may be supported by a location server that can reside in different entities. In one design, the location server may obtain positioning information (e.g., measurements) for a target device via a common positioning protocol. The location server may use the common positioning protocol regardless of where it resides and may communicate with other entities via this protocol. The location server may determine location information (e.g., a location estimate) for the target device based on the positioning information. In another aspect, positioning may be supported by transporting multiple positioning messages together. In yet another aspect, positioning may be supported by transporting a positioning message containing multiple parts defined by different organizations. In yet another aspect, positioning may be supported with shared measurement data units and/or shared assistance data units that may be applicable for different positioning methods.

Abstract: Techniques for supporting eCalls are described. In an aspect, an eCall indicator may be used to indicate an eCall being established. In one design, a terminal may generate a message including an eCall indicator and may send the message to originate an eCall. The eCall indicator may indicate (i) whether or not a call is an eCall or (ii) whether an eCall is initiated automatically by the terminal or manually by a user. In another aspect, a terminal may avoid sending signaling for mobility management and connection management to wireless networks except for eCalls and designated calls. The terminal may avoid performing location updating, performing registration, responding to paging requests, etc. The terminal may exchange signaling with a wireless network for an eCall initiated by the terminal. After the eCall is initiated, the terminal may perform location updating with the wireless network and call establishment for the eCall.

Abstract: Techniques for positioning access points and terminals in WLANs and other wireless networks are described. For access point positioning, measurements are obtained for at least one access point in a WLAN. The measurements may be based on transmission sequences (e.g., beacon frames) transmitted periodically by each access point. The measurements may be made by multiple terminals at different locations or a single mobile terminal at different locations. The location of each access point is determined based on the measurements and known locations of the terminal(s). For terminal positioning, measurements for at least one access point in a WLAN are obtained. The location of the terminal is determined based on the measurements and known location of each access point. The measurements may be round trip time (RTT) measurements, observed time difference (OTD) measurements, time of arrival (TOA) measurements, signal strength measurements, signal quality measurements, etc.

Abstract: Techniques for routing an emergency call originated by a mobile station via a femto access point (FAP) in a wireless network and for locating the mobile station are described. In an aspect, the emergency call may be routed to an appropriate emergency center based on location information for the FAP. In one design, the location information for the FAP may include a macro cell identity (ID) and/or a macro Mobile Switching Center (MSC) ID determined based on the FAP location. The macro cell ID and/or 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. In another design, the location information for the FAP may include a location estimate for the FAP. The location estimate may be used to access a geographic database, which may store routing information for emergency centers for different geographic areas.

Abstract: Techniques for supporting triggered location services are described. In one design, at least one location related measurement for a terminal may be obtained and used to detect for a trigger event. For an equidistance triggered service, a trigger event may be declared if the distance traveled by the terminal exceeds a predefined distance. For a relative terminal to terminal triggered service, a trigger event may be 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 may be declared if the maximum velocity of the terminal exceeds a predefined velocity. For a time-distance-velocity combination triggered service, a trigger event may be declared based on distance traveled by the terminal, velocity of the terminal, and time since the last report. For all services, a report may be sent if a trigger event has occurred.
