Abstract
A method and apparatus for robust adjustment of access and mobility management functions are disclosed. In one embodiment, a method includes: receiving a radio access network (RAN)-user equipment (UE) identifier from a first access and mobility management function (AMF), the RAN-UE identifier configured to identify a UE or UE context for a RAN; producing an AMF-UE identifier, the AMF-UE identifier configured to identify the UE or UE context for a second AMF; selecting a transport network layer association (TNLA) link towards a RAN; and sending the AMF-UE identifier to the RAN.
Claims4
A method, comprising:
- receiving, by a second access and mobility management function (AMF), a radio access network (RAN)-user equipment (UE) identifier from a first AMF, the RAN-UE identifier configured to identify a UE for a RAN,
- wherein the RAN-UE identifier is a RAN UE N2AP ID;
- producing, by the second AMF, an AMF-UE identifier, the AMF-UE identifier configured to identify the UE for the second AMF,
- wherein the AMF-UE identifier is an AMF UE N2AP ID;
- selecting, by the second AMF, a transport network layer association (TNLA) link to the RAN;
- and
- sending, by the second AMF, the AMF-UE identifier to the RAN via the TNLA link.
