Methods and arrangements in a cellular radio communication system

摘要

A user equipment (120), a first radio network node (130) and a positioning node (110) are comprised in a Long Term Evolution system (100). The user equipment (120) receives (2000, 2010) a request for path loss related information. The user equipment (120) estimates (2020) and sends (2030, 2040) the path loss related information. Moreover, the first radio network node (110, 130) sends (2010, 2060) a request for the path loss related information. The first radio network node (110, 130) receives (2030) the path loss related information. Furthermore, the positioning node (110) sends (2000, 2050) a request for the path loss related information. The positioning node (110) receives (2040, 2080) the path loss related information. In some examples, the positioning node (110) associates (2110) the path loss related information to at least one cell area description, thereby creating a database of cell area descriptions and path loss related information associated thereto.

主权项

1. A method in a user equipment for providing path loss related information to a location service, wherein the user equipment is served by a first radio network node using a first radio access technology, wherein the user equipment and the first radio network node are comprised in a Long Term Evolution system, the method comprising:
receiving a request for path loss related information, wherein the request relates to requesting information for use by the location service; estimating a path loss value, wherein said estimating comprises measuring the path loss value with respect to the first radio network node using at least a second radio access technology that is different from the first radio access technology; and sending the path loss value, in response to the received request, thereby providing the path loss value to the location service.
