Location reporting in a cellular telecommunications network
View Patent ↗This disclosure relates to a method in a cellular telecommunications network, and a network node for implementing the method, the cellular telecommunications network including a base station having a coverage area, and a plurality of User Equipment (UE) located within the base station's coverage area, the method including instructing a first plurality of UEs to report their location; associating an occurrence of a connection performance indication for each UE of the first plurality of UEs with a reported location for that UE; defining a first geographical region in which the density of reported locations is above a first density threshold; defining a second geographical region in which the density of reported locations is above a second density threshold, wherein the area of the first geographical region is greater than the area of the second geographical region; instructing a second plurality of UEs within the first geographical region to report their location at a first reporting rate; and instructing a third plurality of UEs within the second geographical region to report their location at a second reporting rate.
1. A method in a cellular telecommunications network, the cellular telecommunications network including a base station having a coverage area, and further including a plurality of User Equipment (UE) located within the coverage area of the base station, the method comprising:
instructing a first plurality of UEs each to report a respective location of the UE;
associating an occurrence of a connection performance indication for each UE of the first plurality of UEs with a reported location for that UE;
defining a first geographical region in which a density of reported locations is above a first density threshold;
defining a second geographical region in which a density of reported locations is above a second density threshold, wherein an area of the first geographical region is greater than an area of the second geographical region;
instructing a second plurality of UEs within the first geographical region each to report a respective location at a first reporting rate; and
instructing a third plurality of UEs within the second geographical region each to report a respective location at a second reporting rate.
2. The method as claimed in claim 1 , further comprising, initially, determining that a count of occurrences of connection performance indications for one or more UEs of the plurality of UEs satisfies a threshold.
3. The method as claimed in claim 1 , wherein the connection performance indication is a Radio Link Failure (RLF).
4. The method as claimed in claim 1 , performed by a first base station.
5. The method as claimed in claim 1 , performed by a network node, wherein the network node is in communication with one or more base stations.
6. A non-transitory computer-readable storage medium storing a computer program comprising instructions which, when the computer program is executed by a computer, cause the computer to carry out the method of claim 1 .
7. A system comprising:
at least one processor and memory having stored thereon a computer program which, when executed, causes the at least one processor and memory to, in a cellular telecommunications network, the cellular telecommunications network including a base station having a coverage area, and further including a plurality of User Equipment (UE) located within the coverage area of the base station:
instruct a first plurality of UEs each to report a respective location of the UE;
associate an occurrence of a connection performance indication for each UE of the first plurality of UEs with a reported location for that UE;
define a first geographical region in which a density of reported locations is above a first density threshold;
define a second geographical region in which a density of reported locations is above a second density threshold, wherein an area of the first geographical region is greater than an area of the second geographical region;
instruct a second plurality of UEs within the first geographical region each to report a respective location at a first reporting rate; and
instruct a third plurality of UEs within the second geographical region each to report a respective location at a second reporting rate.
8. A network node for a cellular telecommunications network, the cellular telecommunications network including a plurality of User Equipment (UE) the network node comprising:
a transceiver configured to receive data from the plurality of UEs;
memory configured to store the data; and
a processor configured to:
instruct a first plurality of UEs each to report a respective location of the UE;
associate an occurrence of a connection performance indication for each UE of the first plurality of UEs with a reported location for that UE;
define a first geographical region in which a density of reported locations is above a first density threshold;
define a second geographical region in which a density of reported locations is above a second density threshold, wherein an area of the first geographical region is greater than an area of the second geographical region;
instruct a second plurality of UEs within the first geographical region each to report a respective location at a first reporting rate; and
instruct a third plurality of UEs within the second geographical region each to report a respective location at a second reporting rate.
9. The network node as claimed in claim 8 , wherein the network node is a base station.
