Techniques described herein are directed toward an enhanced LTE positioning protocol for multiple location reporting (with non-final and final fixes) that can be utilized by a user equipment (UE) to help prevent a disruption of the communication of information for a final location fix from the UE to a location server. In particular, techniques help ensure that the location server will not acknowledge receipt of the information provided by the UE in communication for a non-final fix.

Control plane LCS solution for improving multiple reporting LPP messaging

Disclosed are methods and systems for supporting positioning operations in a cellular communication network including locating a mobile device in response to an emergency event. In one particular implementation, a first position fix may be provided quickly by a mobile device and may be followed by a second, more accurate, position fix at a later time. In particular implementations, the first and second position fixes may be provided using the 3GPP Long Term Evolution (LTE) Positioning Protocol (LPP) as part of a single LPP transaction and may further be provided using a user plane or control plane location solution.

Methods and systems for returning an early positioning fix

An implementation of a system, device and method for communicating location data of a mobile station, enhancing location data, optimally communicating Assistance Data, and/or reducing rebids of Measure Position Request messages in a wireless network.

GPS yield for emergency calls in a mobile radio network

Techniques disclosed herein provide for enhanced LTE Positioning Protocol (LPP) Reliable Transport where the receiver of an LPP message sends a non-piggybacked acknowledgement. An example method for executing on a mobile device a protocol session with a location server includes sending a first protocol session message associated with a first protocol session to the location server, entering a wait-for-acknowledgement state in which uplink transmissions from the mobile device to the location server are suspended while waiting for an acknowledgement from the location server in response to the first protocol session message, receiving a second protocol session message associated with a second protocol session which is not an acknowledgement to the first protocol session message but includes information requested in the first protocol session message; exiting the wait-for-acknowledgement state responsive to receiving the second protocol session message; and performing an action using the information received in the second protocol session message.

Enhanced LTE positioning protocol information transfer procedures for control plane LCS on LTE

A location server, such as a Serving Mobile Location Center (SMLC) or E-SMLC and mobile terminal selectively implement the reliable transport mechanism used in, e.g., LPP or LPPe protocols, thereby decreasing unnecessary delays. The reliable transport mechanism may be selectively implemented by not requiring an acknowledgement for specific messages, such as an unsolicited assistance data message. When assistance data is solicited, however, the responsive assistance data message includes an acknowledgement request as per the reliable transport mechanism.

Selected acknowledgment positioning optimizations

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.
