Embodiment Construction

[0022] Work is underway to design benchmarks for next-generation WANs. In order to reduce energy consumption in the network and fully realize the utilization of high gain beamforming or other multi-antenna techniques, the concept of separation of the control / broadcast layer from the data plane has been defined.

[0023] The control layer (denoted here as the system control plane SCP) is responsible for functions related to random access and paging. In order to reduce network energy consumption in future wireless communication systems, broadcast signals are expected to occur less often than the broadcast of reference signals in current cellular systems. Furthermore, reference signals in future wireless communication systems are not envisaged to be node specific as in current systems. In such a system, a wireless device in idle mode would not be able to recognize or "see" the various nodes as it moves into the network. A wireless device in idle mode will only be able to detect...

Abstract

A solution for providing differentiated location services in a wireless communication system is provided. For example, there is provided a method performed by a wireless device that includes requesting high precision positioning information from a network (eg, from a network node). The method also includes obtaining information from the network in response to the request, the information being valid for a predetermined period of time, and enabling the wireless device to obtain the highly accurate positioning information during the predetermined period of time. The method further includes: performing positioning or assisting in performing positioning based on the obtained high-precision positioning information.

Description

technical field [0001] The present invention relates to positioning in wireless communication networks. Background technique [0002] In prior art networks such as GSM, WCDMA, LTE and WiFi, distinctly different signals are sent from each network cell. In LTE, for example, each cell is associated with a PCI (Physical Cell Identity), which is a locally unique signal used to derive sequences for eg demodulation and synchronization signals. In addition, Positioning Reference Signals (PRS) such as in LTE are also derived from PCI. At any given location, the sum of all locally unique signals (eg, PCI and / or PRS) typically creates a fingerprint that is unique to that particular location. [0003] In such prior art systems, so-called "over the top" (OTT) and / or third party actors can take advantage of this feature to provide location services, such as location-based advertising, based on network fingerprints. By comparing eg global positioning GPS information available in certain...
