Abstract
A communications system comprising a core network, a radio access network and at least one user equipment device, wherein: the core network is configured for communicating with the user equipment device to form a first estimate of the location of the user equipment device; the radio access network is configured for communicating with the user equipment device to form a second estimate of the location of the user equipment device; and the core network is configured for forming a third estimate of the location of the user equipment device by synthesizing the first and second estimates.
Claims30
A location estimating method applied in a location management function entity, the method comprising:
- obtaining a first estimate of a location of a terminal device, and a second estimate of a location of a terminal device;
- wherein the first estimate of the location of the terminal device is obtained by a core network communicating with the terminal device, and the second estimate of the location of the terminal device is obtained by a radio access network communicating with the terminal device;
- and
- obtaining a third estimate of the location of the terminal device by combining the first estimate and the second estimate.
A location management function apparatus for use in a communication network, the location management function apparatus comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions which, when executed by the processor, cause the apparatus to:
- obtain a first estimate of a location of a terminal device, and a second estimate of a location of the terminal device;
- wherein the first estimate of the location of the terminal device is obtained by a core network communicating with the terminal device, and the second estimate of the location of the terminal device is obtained by a radio access network communicating with the terminal device;
- and
- obtain a third estimate of the location of the terminal device by combining the first estimate and the second estimate.
A communications system comprising a core network and a radio access network, wherein:
- the core network is configured to communicate with a terminal device to obtain a first estimate of a location of the terminal device;
- the radio access network is configured to communicate with the terminal device to obtain a second estimate of the location of the terminal device;
- and
- the core network is configured to obtain a third estimate of the location of the terminal device by combining the first estimate and the second estimate.
A non-transitory computer readable storage medium, comprising a computer program, wherein when the computer program is run on a computer, the computer is enabled to perform:
- obtaining a first estimate of a location of a terminal device, and a second estimate of the location of the terminal device;
- wherein the first estimate of the location of the terminal device is obtained by a core network communicating with the terminal device, and the second estimate of the location of the terminal device is obtained by a radio access network communicating with the terminal device;
- and
- obtaining a third estimate of the location of the terminal device by combining the first estimate and the second estimate.
