摘要:
The position of a mobile device served in a cell of a serving node of a wireless communication network is estimated by estimating an angle-of-arrival (AoA) between the mobile device and the serving node based on a precoding matrix indicator (PMI) determined for the serving node in a downlink direction or for the mobile device in an uplink direction. Also estimated is the AoA between the mobile device and a non-serving neighbor node of the wireless communication network based on a PMI determined for the neighbor node in the downlink direction or for the mobile device in the uplink direction. The downlink and/or uplink AoA estimation can be further enhanced by employing interference cancellation in the mobile device and in the radio node, respectively. The position of the mobile device is estimated based on the estimated AoAs.

摘要:
A method in a positioning node (100) for selecting a positioning method is provided. The positioning node is connected to a plurality of radio access networks of different access technologies and to a plurality of core networks. The positioning node receives (201) from a requesting node, a request for a positioning of a terminal. The request comprises at least one of a plurality of client types, and at least one of a plurality of quality of service parameters. The positioning node then selects (204) at least one positioning method of a plurality of positioning methods of the different plurality of radio access networks and or radio access technologies for positioning the terminal. The selection of the positioning method is based on the received at least one client type and at least one quality of service parameters of the request.

Presented is a system and methods for allowing the translation the civic address portion of a positioning message to different languages. The positioning message can be in response to an Emergency-911 call providing much better information regarding the location of the caller associated with the user equipment on a wireless network. The positioning message can contain an indicator of the originating language or a translation of the language from the originating language to the preferred or required language of the destination address. The positioning message can also contain a series of translated messages representing all the languages supported by the wireless network.
摘要:
One aspect of the present invention extends the number of client and/or service types used in location-based services. The extension provides richer definitions for use in selecting the optimal or otherwise best suited positioning sequences to be used in fulfilling given positioning requests. For example, some types of commercial-related positioning requests are better satisfied with quicker-but-lower-accuracy position determinations, while other types benefit from more-accurate-but-slower position determinations. These and other benefits are provided by extending the type definitions used to identify commercial positioning requests. For example, a UE may be configured to send positioning requests that indicate the extended client or service types. As another example, the network node(s) involved in generating or processing such requests are configured to understand the extended type definitions and/or to map the extended definitions to QoS requirements, or to particular positioning sequences, for requesting that a positioning node carry out that particular positioning sequence.
摘要:
Methods and apparatus for handling positioning information by sending a positioning result, which can include uncertainty information, in at least one of a graphical format and a text-encoded graphical format. Positioning result accuracy, which can be important for emergency services, is improved by avoiding conversion between positioning result formats. Positioning results can be flexibly delivered, without concern for the particular radio access technology used in a communication network. The graphical format can be a vector graphics format, such as Scalable Vector Graphics and Wireless Vector Graphics. The text-encoded graphical format can be based on the extensible Markup Language, the positioning information in the graphical and/or text-encoded graphical format can be signaled by a messaging service.

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.
