摘要： A network node (44) herein advantageously eliminates or at least mitigates timing ambiguities associated with when a user equipment (36) is to perform assisted positioning measurements. To do so, the network node (44) generates assistance data to indicate that a first cell for the measurements (e.g., a reference cell) has a greater positioning occasion periodicity than it actually has. This greater periodicity may be, for example, a multiple of the first cell's actual positioning occasion periodicity. Regardless, the node (44) also generates the assistance data to indicate positioning occasion timing for at least a second cell relative to positioning occasion timing for the first cell that is based on this greater periodicity. Finally, the node (44) sends this generated assistance data to the user equipment to assist with the positioning measurements.

摘要： Techniques are disclosed for determining measurement uncertainty of and/or multipath effects on positioning measurements, based on the residual deviations between timing measurements and high-accuracy location results. An example method begins with collecting (510) a plurality of timing measurements or ranging measurements, or both, each measurement corresponding to at least one anchor node antenna having a known location. A measurement deviation is determined (520) for each measurement by comparing the measurement to a corresponding reference location. The measurement deviations are used (530) to estimate measurement quality for one or more subsequent positioning measurements, and/or uncertainty associated with one or more subsequent positioning estimates, and/or an effect of multipath on subsequent positioning measurements or estimates. In some embodiments, a covariance matrix is calculated from the measurement deviations and is used to determine statistical information or multipath effects for measurements corresponding to a particular one of the anchor node antennas.

摘要： A method and system for determining a position of a UE includes a first network node receiving a request for positioning information about the UE. The first network node requests a first positioning procedure at a first location node. The first location node determines using the first positioning procedure that involvement by a second location node is needed. The first location node initiates a trigger for positioning information about the UE to be sent to the second location node. The second location node, upon receiving the trigger for positioning information and determining the presence of an environment measurement parameter, determines the position information of the UE by performing a second positioning procedure based on the environment measurement parameter, and sends a position calculation response with the positioning information.

摘要： A method in a first network node (105) for estimating a first timing offset difference between a first timing offset of a first base station and a second timing offset of a second base station, is provided. The first network node (105) receives Uplink Time Difference Of Arrival, UTDOA, measurements. The UTDOA measurements relate to a first UTDOA time difference. The first network node (105) further receives Observed Time Difference Of Arrival, OTDOA, measurements. The OTDOA measurements relate to a first measured OTDOA time difference. The first network node estimates a first timing offset difference between a first timing offset of the first base station and a second timing offset of the second base station based on the first UTDOA time difference and the first measured OTDOA time difference.

摘要： The present invention relates to positioning in a communication network. In Long Term Evolution, LTE networks the positioning server E-SLMC needs routing information in order to communicate with individual base stations, eNodeBs. For LTE networks configured with one Mobility Management Entity, MME or one pool of MMEs, the routing information can be obtained by interrogating the MME or an arbitrary MME in the MME pool. However, if the network is configured with several MME pools serving different sets of eNodeBs, the E- SLMC has now knowledge of which MME or MME pool that is serving a certain eNodeB. The invention includes a method and a position server (111) configured to quickly determine which MME pool (120,130) is serving a certain eNodeB (141-153) so that the relevant routing information necessary for the positioning server (111) to communicate with the eNodeBs (141-153) is obtained.
