US 12,114,283 B2 · Methods and systems for support of location for the internet of things

Abstract

Methods and techniques are described for supporting location services for a user equipment (UE) that is using Narrowband Internet of Things radio access or Cellular Internet of Things features to access a wireless network. The techniques include enabling support for a last known location of a UE, using previously obtained location measurements, when a UE is not reachable from a wireless network for positioning. The techniques also include limiting positioning protocol interaction between a UE and a location server via a reduced maximum message size, reduced message volume and longer response and retransmission timers. The techniques further include enabling a UE to obtain location measurements when not connected to a wireless network, enabling periodic and triggered location of a UE in which a UE evaluates location triggers while not connected to a wireless network, enabling use of deferred location and enabling improved location security.

Claims20

Dependent claims

A method comprising:

receiving location measurements for a user equipment (UE), wherein the UE has a connection to a wireless network;
storing the location measurements and a timestamp, the timestamp corresponding to a time at which the UE enters an idle state;
receiving a location request for the UE after the UE connection to the wireless network has been released;
transmitting the location measurements to a location server while the UE connection to the wireless network is released with an indication that a last known location is requested for the UE;
and
receiving a response from the location server comprising the last known location for the UE.
