Abstract
Systems, methods, apparatuses, and computer program products for enhanced location services in 5G are provided. One method may include storing, at a network node, at least one of data network access identifier(s) (DNAIs), an indication of serving area(s), and/or slice information that is supported by a location management function (LMF) with or in a LMF profile. The method may also include transmitting, to a consumer network function (NF), the LMF profile with the at least one of DNAIs, indication of serving area(s), or slice information supported by the LMF.
Claims20
An apparatus, comprising:
- at least one processor;
- and
- at least one memory storing instructions which, when executed by the at least one processor, cause the apparatus at least to:
- determine to change a first location management function that serves a user equipment, the determination to change the first location management function being based on an updated location of the user equipment, and a change from a first access and mobility management function that served the user equipment to a second access and mobility management function that serves the user equipment;
- transmit, to a network node, a location management function discovery request, based on the determination to change the first location management function;
- receive, from the network node, a plurality of location management function profiles, based on the location management function discovery request,
- wherein the plurality of location management function profiles comprise a location management function profile of a second location management function,
- the location management profile of the second location management function comprises an indication of serving area, and slice information,
- the indication of serving area comprises at least one tracking area identifier, and
- the at least one tracking area identifier and the slice information are stored in the location management function profile of the second location management function via registration of an instance of the second location management function;
- and
- select the second location management function for the updated location of the user equipment and the second access and mobility management function, based on the at least one tracking area identifier and the slice information stored in the location management function profile of the second location management function.

A method, comprising:
- determining to change a first location management function that serves a user equipment, said determining to change the first location management function being based on an updated location of the user equipment, and a change from a first access and mobility management function that served the user equipment to a second access and mobility management function that serves the user equipment;
- transmitting, to a network node, a location management function discovery request, based on said determining to change the first location management function;
- receiving, from the network node, a plurality of location management function profiles,
- wherein the plurality of location management function profiles comprise a location management function profile of a second location management function,
- the location management profile of the second location management function comprises an indication of serving area, and slice information,
- the indication of serving area comprises at least one tracking area identifier, and
- the at least one tracking area identifier and the slice information are stored in the location management function profile via registration of an instance of the second location management function;
- and
- selecting the second location management function for the updated location of the user equipment and the second access and mobility management function, based on the at least one tracking area identifier and the slice information stored in the location management function profile of the second location management function.

A method, comprising:
- receiving, from a consumer network function, a location management function discovery request, based on a determination to change a first location management function that serves a user equipment, the determination to change the first location management function being based on an updated location of the user equipment, and a change from a first access and mobility management function that served the user equipment to a second access and mobility management function that serves the user equipment;
- and
- transmitting, to the consumer network function, a plurality of location management function profiles, based on the location management function discovery request,
- wherein the plurality of location management function profiles comprise a location management function profile of a second location management function,
- the location management profile of the second location management function comprises an indication of serving area, and slice information,
- the indication of serving area comprises at least one tracking area identifier,
- the at least one tracking identifier and the slice information are stored in the location management function profile of the second location management function, at a network node, via registration of an instance of the second location management function to the network node,
- wherein said transmitting the plurality of location management function profiles enables a selection of the second location management function for the updated location of the user equipment and the second access and mobility management function, based on the at least one tracking area identifier and the slice information stored in the location management function profile of the second location management function.
