US 10,952,028 B2 · Location of a mobile device with wireless access using a user plane location solution

Abstract

Techniques are discussed herein for supporting location of a user equipment (UE) with wireless access using a user plane (UP) location solution like SUPL. To locate the UE, an initial UP location session is established between the UE and a location server (LS) during which the LS requests location measurements from the UE. The UE obtains the location measurements by ending the location session and entering an idle state, after indicating this intent to the LS. The UE sends the location measurements to the LS by reentering a connected state and starting a new UP location session with the LS, which may be associated with the initial location session using common identification information. The techniques may be used for a UE with only a single RF chain (e.g. a UE that supports NB-IoT or other narrowband wireless access).

Dependent claims

A method for supporting location services for a user equipment (UE) performed by the UE, comprising:

beginning a first user plane location session with a location server;
receiving a non-periodic request for location measurements from the location server;
sending an indication to the location server that the UE will enter an idle state in which the UE will not be connected with a wireless network;
prior to measuring the location measurements, ending the first user plane location session with the location server;
entering the idle state;
obtaining the location measurements while in the idle state;
re-entering a connected state with the wireless network;
beginning a second user plane location session with the location server;
and
sending the location measurements to the location server using the second user plane location session.

7 more elements

A user equipment (UE) capable of supporting location services, comprising:

at least one wireless transceiver configured to wirelessly communicate with a wireless network;
and
at least one processor coupled to the at least one wireless transceiver and configured to:
begin via the at least one wireless transceiver a first user plane location session with a location server;
receive via the at least one wireless transceiver a non-periodic request for location measurements from the location server;
send via the at least one wireless transceiver an indication to the location server that the UE will enter an idle state in which the UE will not be connected with the wireless network;
prior to measuring the location measurements, end via the at least one wireless transceiver the first user plane location session with the location server;
enter the idle state;
obtain via the at least one wireless transceiver the location measurements while in the idle state;
re-enter a connected state with the wireless network;
begin via the at least one wireless transceiver a second user plane location session with the location server;
and
send via the at least one wireless transceiver the location measurements to the location server using the second user plane location session.
