Abstract:
Various methods, apparatuses and/or articles of manufacture are provided which may be implemented as part of a mobile device to selectively transition operation of the mobile device from one communication mode to another communication mode. For example, a mobile device may selectively transition operation from one communication mode to another communication mode based, at least in part, on a determination that certain signaling environment attributes which were previously experienced and identified may once again have been experienced and identified.
Abstract:
An application executed within a mobile station to be triggered only by a network element, such as a mobile positioning center (MPC) or a Mobile Center (MC). The network element is coupled to a base station. The network element is responsible for authorizing an application that is either resident within the mobile station or that is run in a device that is resident elsewhere in the network. The mobile station communicates with the network element over a communication session through the base station and other infrastructure components. The mobile station initiates a mobile originated positioning session over a second communication session with a positioning assistance server.
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 are discussed for supporting positioning with ambiguous wireless cells. An ambiguous cell may employ a Distributed Antenna System (DAS), one or more Remote Radio Heads (RRHs), repeaters or relays, or may broadcast the same Positioning Reference Signal (PRS) as another nearby cell. In example techniques, measurements of a radio source in an ambiguous cell (e.g. a DAS antenna element or RRH) may be used to identify the measured radio source. The measurements may be for the Observed Time Difference of Arrival (OTDOA) position method or the Enhanced Cell ID (ECID) position method. The determination of the measured radio source for an ambiguous cell may be used to improve a location estimate for a user equipment (UE).
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:
Techniques for supporting positioning are described. In an example implementation, a method of positioning may be provided which comprises, at a mobile station, receiving at least one signal from a transmitter device. Here, the received signal may comprise an identity of the transmitter device. The mobile station may send an identity of the transmitter device to a location server, and receive one or more positioning assistance messages from the location server, wherein the one or more positioning assistance messages are generated in response to the identity of the transmitter device. The mobile station may subsequently perform positioning based at least in part on the one or more positioning assistance messages received from the location server.
Abstract:
The subject matter disclosed herein relates to a system and method for establishing communication between a low duty cycle device and other devices through a wireless communication network. In one particular implementation, the low duty cycle device may awaken from a hibernating state in synchronization with transmission of messages.
Abstract:
Techniques for publishing location information associated with a non-geotagged transceiver are disclosed. A method for publishing a position of a non-geotagged transceiver in a wireless communication system includes determining a first position of the non-geotagged transceiver based on a periodic neighbor list, determining a second position of the non-geotagged transceiver based on an accumulated neighbor list, determining if the first position and the second position agree, publishing a third position if the first position and the second position agree, such that the third position is determined based on the union of the periodic neighbor list and the accumulated neighbor list, and resetting the accumulated neighbor list if the first and second position do not agree.
Abstract:
A dual SIM mobile terminal, such as a Dual SIM Dual Active (DSDA) mobile terminal, connects to a network and performs a user plane or control plane positioning session through the network. When the positioning session is originated by the mobile terminal, either SIM card may be used to connect to its associated network. When the positioning session is originated by another entity in the network, either SIM card may be used for the positioning session. When the mobile terminal connects to a network for an emergency call using either SIM card and an emergency positioning session is performed through the network, the emergency positioning session is permitted only during the emergency call and an emergency callback period and permitted only on a subscription on which the emergency call originated, and no non-emergency positioning sessions with either SIM card is permitted during the emergency positioning session or emergency call.
