Abstract
Methods, systems, and devices for wireless communication are described. A method may include determining to modify current-allowed network slices used by a user equipment (UE) based on a network-trigger; identifying new-allowed network slices for the UE based on the determining; selecting a target access and mobility management function (AMF) based on the new-allowed network slices, the target AMF is accessible by the source AMF; and triggering an AMF relocation based on the selecting.
Claims30
A method for wireless communication at a source access and mobility management function (AMF), comprising:
- determining to modify current-allowed network slices supported for a user equipment (UE) based at least in part on a network-trigger;
- identifying a new-allowed network slice supported for the UE based at least in part on the determining;
- determining that the source AMF is unable to serve the new-allowed network slice;
- transmitting an indication to the UE to initiate a registration procedure, based at least in part on the determining that the source AMF is unable to serve the new-allowed network slice;
- selecting a target AMF based at least in part on the transmitting, wherein the target AMF is associated with the new-allowed network slice;
- and
- triggering an AMF relocation based at least in part on the selecting.
A method for wireless communication at a user equipment (UE), comprising:
- receiving, from a source access and mobility management function (AMF), a configuration message comprising an identifier associated with a target AMF, a status of existing active protocol data unit (PDU) sessions of the UE, a new-allowed network slice, or an indication to initiate a registration procedure, or a combination thereof;
- initiating a registration procedure based at least in part on the receiving;
- identifying an active PDU session based at least in part on the receiving, wherein the active PDU session is unsupported by the new-allowed network slice;
- and
- locally releasing the active PDU session based at least in part on the initiating.
A method for wireless communication at an access network (AN), comprising:
- receiving, from a user equipment (UE), a radio resource control (RRC) connection request comprising network slice selection assistance information (NSSAI);
- identifying a source access and management function (AMF) associated with current-allowed network slices of the UE based at least in part on the NSSAI;
- determining to modify the NSSAI based at least in part on a trigger indication;
- identifying a new-allowed network slice supported for the UE based at least in part on the determining;
- determining that the source AMF is unable to serve the new-allowed network slice;
- receiving a request to initiate a re-registration procedure based at least in part on the source AMF being unable to serve the new-allowed network slice;
- selecting a target AMF to serve the UE based at least in part on the request;
- and
- triggering an AMF relocation based at least in part on the selecting.
A method for wireless communication at an access network (AN), comprising:
- determining to modify the network slice selection assistance information (NSSAI) based at least in part on a trigger indication;
- identifying a new-allowed network slice supported for the UE based at least in part on the determining;
- determining that a source access and management function (AMF) associated with current-allowed network slices is unable to serve the new-allowed network slice;
- identifying a re-registration request;
- selecting a target AMF to serve the UE based at least in part on the re-registration request, wherein the target AMF is associated with the new-allowed network slice;
- and
- triggering an AMF relocation based at least in part on the selecting, wherein the AMF relocation comprises initiating a redirection of the UE from the source AMF to the target AMF.
