Embodiment Construction

[0050] In the following description, similar reference numerals may be used to denote similar elements, units, modules, circuits, nodes, components, items or characteristics, where applicable. In the figures, features that are only present in certain embodiments are generally indicated by dashed lines.

[0051] As part of the development for the embodiments herein, problems with existing approaches will first be identified and discussed.

[0052] The problem can be generalized as: According to existing methods, some nodes in the communication network may collect more information (which may be useful for the location of devices using multilateration) than existing methods are currently able to process. Thus, existing methods result in sub-optimal positioning procedures and wasted energy, processing, and radio resources. This problem will now be explained in further detail before presenting the embodiments herein that address this problem.

[0053] For the purpose of simplifyi...

Abstract

A method performed by a wireless device (120) for supporting positioning of the wireless device (120) in a wireless communication network (100). The wireless device (120) receives (501, 801) from a first network node (110), a positioning request. The wireless device (120) is served in by the first network node (110) when receiving the positioning request. The positioning request requests the wireless device (120) to initiate a multilateration. In response, the wireless device (120) sends (504, 804a) to a second network node (113) comprised in the wireless communication network (100), a positioning access request indicating that the access request relates to a multilateration positioning and requesting the second network node (113) to estimate a timing advance (TA) for the wireless device (120). The wireless device (120) sends (505, 804a, 804c), to the second network node (113), an obtained device identifier identifying the wireless device (120), and an obtained source identifier identifying the first network node (110).

Description

technical field [0001] Embodiments herein relate to systems for supporting devices (e.g., wireless devices) in a wireless communication network (e.g., a telecommunications network, such as a Global System for Mobile Communications (GSM)-based network, such as Extended Coverage GSM (EC-GSM-IoT)). Method and device for positioning. In particular, the present disclosure relates to a wireless device and a method performed thereby for supporting location of the wireless device in a wireless communication network. The present disclosure also relates to a second network node and a method performed by it for supporting positioning of a wireless device in a wireless communication network. Background technique [0002] A communication device such as a wireless communication device (which may be referred to simply as a wireless device) may also be referred to as eg a user equipment (UE), a mobile terminal, a wireless terminal and / or a mobile station (MS). Wireless devices are capable...
