Methods, network node and wireless device for supporting positioning of the wireless device

Abstract

Methods, network node (200) and wireless device (202) for supporting positioning of the wireless device in a wireless network. The network node requests (2:4) the wireless device to provide a positioning related report when a mobility criterion is fulfilled, which criterion may be selected (2:3) based on sensor capabilities of the device. The wireless device monitors (2:5) sensor measurements andevaluates the mobility criterion. When the mobility criterion is fulfilled the wireless device provides (2:6) the positioning related report to the network node which then obtains (2:7) the position or mobility status of the wireless device based on the positioning related report which may contain information related to said mobility status and / or sensor measurements made in the device.

Description

technical field [0001] The present disclosure generally relates to network nodes, wireless devices and methods thereof for supporting positioning of wireless devices in a wireless network. Background technique [0002] In this disclosure, the term "wireless device" is used to denote devices capable of radio communication with a wireless network by sending and receiving radio signals such as, for example, mobile phones, tablets, laptops, and machine-to-machine (M2M) devices (also Any communicating entity known as a Machine Type Communication (MTC) device). Another common term in the art is "User Equipment (UE)," which is often used herein as a synonym for wireless device. [0003] Further, the term "network node" is used herein to denote any node of a wireless network operable to handle positioning activities as described herein. A network node may be a positioning node or a location server connected to a plurality of base stations or radio nodes in a wireless network. A n...

Problems solved by technology

[0013]However, location techniques that use location-related information such as mobility state and sensor measurements require wireless devices to generate and report such information to the network, causing wireless networks and their radios to Increased load on resources

Reporting that provides such location-related information also increases power consumption in the wireless device, and can be too high, especially if it is difficult or even impossible to charge the device's battery frequently enough

Therefore, a tradeoff may have to be made between accurate location determination and network load plus power consumption
