Abstract: Techniques for maintaining location continuity for a user equipment (UE) following handover are described. The UE communicates with a first radio access network (RAN) and is served by a source serving node and a source location server prior to handover. The UE communicates with a second RAN and is served by a target serving node and a target location server after the handover. In an aspect, location continuity may be maintained for the UE by transferring an identity of the target serving node to a location server during handover of the UE. In one design, the target serving node sends its identity to the target location server, which updates a Location and Routing Function (LRF) serving the UE. In another design, for handover from packet-switched domain to circuit-switched domain, the source serving node sends the target serving node identity to the source location server, which updates the LRF.

Abstract: Techniques for initiating and, if desired, modifying location services for Secure User Plane Location (SUPL) and other location architectures are described. To initiate SUPL service, a SUPL Location Platform (SLP) transmits a SUPL initial session message applicable to any service request to a SUPL enabled terminal (SET) and receives in response the service capabilities of the SET. The SLP selects and requests service from the SET consistent with the service capabilities of the SET. The SET may initiate SUPL service by requesting the service capabilities of the SLP. The SET selects and requests service from the SLP that is consistent with the service capabilities received from the SLP. The SET and SLP communicate to determine a position estimate for the SET. The service may be modified before or while communicating between the SET and the SLP to determine a position estimate for the SET.

Abstract: Techniques for supporting positioning for a terminal (sometimes referred to herein as a target device) in a wireless network are described. In an aspect, positioning for a target device includes transmitting a Request Assistance Data message to a location server, the Request Assistance Data message indicating at least one positioning method from a plurality of supported positioning methods. The Request Assistance Data message comprises common parameters that are applicable to all positioning methods indicated in the Request Assistance Data message. The common parameters comprise a serving cell identifier. Positioning for the target device further includes receiving assistance data sent in response to the Request Assistance Data message, and performing positioning based on the received assistance data.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with using D2D communications to support at least a portion of IMS based services. In one example, a first UE is equipped to perform communications with a second UE using an IMS session in which data traffic and signaling traffic are supported through a network, determine that the second UE is within a first proximity threshold of the first UE, establish a D2D communication link with the second UE, and transfer support of the data traffic to the D2D communication link while maintaining the support of the signaling traffic through the network. In an aspect, the first proximity threshold may be a distance, a signaling strength or a signaling quality between the first and second UEs between which D2D communications are supported.

Abstract: Techniques for supporting network independent location services (LCS) are described. In one design, a location center may communicate with a terminal to establish an account for the terminal with the location center for location services. The location center may establish the account for the terminal independent of a home network or a serving network for the terminal. During signup to establish the account, the location center may (i) provide address information for the location center, security information, and/or other information for the location center and (ii) receive public identity information and/or other information for the terminal. The location center may thereafter provide location services to the terminal based on the established account and without interacting with the home or serving network for the terminal. Techniques for supporting delivery of assistance data are also described.

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.
