Abstract: Techniques for supporting network-initiated location services for a terminal are described. A location server may not be able to reach the terminal in a normal manner in certain operating scenarios. The terminal may perform registration with the location server if the terminal determines that it may not be reachable by the location server in the normal manner. For the registration, the terminal may identify itself to the location server, instigate mutual authentication of the terminal and the location server, and provide an Internet Protocol (IP) address of the terminal to the location server. The terminal may perform registration with the location server whenever the IP address changes and/or periodically whenever a timer expires. The terminal may set the timer to a value received from the location server. The location server may use the IP address to send messages to the terminal for network-initiated location services.
Abstract translation: 描述了用于支持终端的网络发起位置服务的技术。 在某些操作情况下，位置服务器可能无法以正常方式到达终端。 如果终端以正常方式确定位置服务器可能不可达，则终端可以执行与位置服务器的注册。 对于注册，终端可以向位置服务器标识其自身，激发终端和位置服务器的相互认证，并将终端的互联网协议（IP）地址提供给位置服务器。 每当IP地址改变时，终端可以执行向位置服务器的注册，并且/或者每当定时器到期时，周期性地执行注册。 终端可以将定时器设置为从位置服务器接收的值。 位置服务器可以使用IP地址向终端发送消息以用于网络发起的定位服务。

Abstract: Techniques for efficiently performing network selection using information stored at a terminal are described herein. The terminal may store coverage information for previously detected wireless networks, cell information for previously detected cells in wireless networks, usage information for previously accessed wireless networks, availability information for previously detected wireless networks, almanac information for cells in wireless networks (e.g., information on cells available at different locations and information for acquiring the cells), and/or other information that may be useful for network selection. The terminal may select a wireless network to attempt acquisition based on the stored coverage information and its current location, the stored cell information and information for the current location (e.g., an identity of a cell detected at the current location), the stored usage information, the stored availability information, and/or the stored almanac information.

Abstract: Techniques to support emergency circuit-mode calls are described. The techniques may be used for various 3GPP and 3GPP2 networks, various location architectures, and various types of User Equipment (UE). A UE establishes a circuit-mode call with a wireless network for emergency services. The UE interacts with a location server indicated by the wireless network. The UE performs user plane location with the location server during the circuit-mode call to obtain a position estimate for the UE. The UE communicates with a PSAP, which may be selected based on the position estimate, for the emergency circuit-mode call. The UE may perform positioning with the location server to obtain an updated position estimate for the UE, e.g., whenever requested by the PSAP.

Abstract: A method of wireless communication performs a public land mobile network (PLMN) search for a higher priority PLMN. The PLMN search includes a candidate PLMN having a different mobile country code (MCC) than a serving PLMN. The method switches to the higher priority PLMN when the PLMN search locates the higher priority PLMN. A method determines whether a user equipment (UE) has transitioned between an international area and a national area. The method triggers PLMN selection in response to the UE having transitioned between the international area and the national area.

Abstract: Techniques for supporting periodic and other location services with Secure User Plane Location (SUPL) and other location architectures are described. The techniques can provide position estimates for a SUPL enabled terminal (SET) to a SUPL agent periodically and/or based on trigger events. A Home SUPL Location Platform (H-SLP) receives from the SUPL agent a request for position estimates for the SET. The H-SLP starts a SUPL location session with the SET. For each of at least one reporting event during the location session, the H-SLP obtains a position estimate for the SET and sends the position estimate to the SUPL agent. The position estimate may be derived by the SET and sent to the H-SLP. Alternatively, the position estimate may be derived by the H-SLP based on measurements from the SET.

Abstract: A user equipment (UE) communicating with a radio access network (RAN) sends to a network entity (e.g., an MSC/SGSN) a request for periodic reporting of the UE location to a client entity. After the request is approved, the MSC/SGSN sends to the RAN signaling to initiate periodic location reporting for the UE. The RAN may request a positioning center (e.g., a SAS) to send assistance data to the UE. The RAN may coordinate and control the periodic location reporting or may pass the control over to the positioning center. For each location reporting, the UE sends location information (e.g., measurements made by the UE or a location estimate computed by the UE) to the RAN. The SAS computes a location estimate if the UE sends measurements. The RAN then sends the location estimate for the UE to the MSC/SGSN, which forwards the location estimate toward the client entity.

Abstract: A reference signal periodically transmitted by a base station in a wireless network can have certain proprietary properties to help prevent detection and utilization of the signal for unauthorized positioning of mobile devices. More specifically, a network node can obscure and introduce time-variation in mapping between positioning signals and a corresponding physical base stations. The network node may also introduce time variations in fields of a base station almanac (BSA) provided to subscribing user equipments (UEs). The information transmitted to the subscribing UEs may be encrypted.

Abstract: Techniques for performing registration in parallel with call establishment to reduce delay are described. A user equipment (UE) performs registration with a communication network, e.g., in response to a user placing an emergency call. The UE establishes the call in parallel with performing registration. The UE updates the call with information (e.g., verified UE identity and/or call back information) obtained from the registration by sending the information to a called entity/party such as a Public Safety Answering Point (PSAP) selected for the emergency call. The UE sends a first message to initiate registration, a second message to initiate establishment of the call, and a third message to update the call with the information obtained from the registration. The established call may be associated with the registration based on a common source IP address in the first, second and third messages and common dialogue information in the second and third messages.

Abstract: Techniques to support emergency voice-over-Internet Protocol (VoIP) calls are described. The techniques may be used for various 3GPP and 3GPP2 networks, various location architectures, and various types of User Equipment (UE). A UE communicates with a visited network to send a request to establish an emergency VoIP call. The UE interacts with a location server instructed by the visited network to obtain a first position estimate for the UE. The UE performs call setup via the visited network to establish the emergency VoIP call with a PSAP, which may be selected based on the first position estimate. The UE may thereafter perform positioning with the location server to obtain an updated position estimate for the UE, e.g., if requested by the PSAP.
