Abstract: Techniques for querying for information on location sessions in a user plane location architecture are described. In an aspect, a location server may send a query message to a terminal to query for information on active location sessions, e.g., when at least one location session for periodic triggered service or area event triggered service is deemed to be active. The terminal may return a response message containing a list of session identifiers (IDs) for the active location sessions, parameters for the active location sessions, capabilities of the terminal, etc. The location server may compare the information received from the terminal and information stored at the location server. The location server may terminate each location session deemed to be active at only the terminal or only the location server. The location server may restart or terminate each location session having inconsistent parameters at the terminal and the location server.

Abstract: Techniques for sending and receiving broadcast information are described. In an aspect, broadcast metadata may be generated for broadcast information and may include location and time criteria used by terminals to filter the broadcast information. Each location and time criterion may include (i) a location criterion given by a target location and a presence or absence requirement and (ii) a time criterion given by a time period in which the location criterion applies. A terminal may receive the broadcast metadata prior to or with the broadcast information, obtain location and time criteria from the broadcast metadata, and filter the broadcast information based on the location and time criteria. The terminal may evaluate each location and time criterion by determining its location within a specified time period and determining whether its location is within or outside a specified target location, as indicated by the presence or absence requirement.

Abstract: Techniques for transferring new capability information in an efficient and backward compatible manner are described. A user equipment (UE) may send a new capability indicator to a wireless network to indicate that the UE has new capability information to send. This new capability indicator may be implemented with a spare bit in an information element included in an initial message sent to the network. The network may request for the information or indicate that it can receive the information. The UE may then send the new capability information to the network upon receiving the request or the indication. Alternatively, the network may convey that it supports transfer of new capability information, e.g., via a broadcast message or a unicast message. The UE may then send new capability information at any time to the network, without having to send the new capability indicator.

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 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 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.
