Abstract
An apparatus of an Access and Mobility Function (AMF) comprises one or more baseband processors to process a request from a new AMF for a user equipment (UE) context transfer for a UE registered to the AMF via a first access type, wherein UE context transfer request includes an indication of a second access type for the UE to register with the new AMF, and to determine whether an entire UE context should be returned to the new AMF based on the second access type. The apparatus can include a memory to store the request.
Claims16
One or more processors of an Access and Mobility Function (AMF) configured to perform operations comprising:
- receiving a request from a new AMF for a user equipment (UE) context transfer for a UE registered to the AMF with a first access type, wherein the request includes an indication of a second access type for the UE to register with the new AMF;
- determining that an interface cannot be relocated to the new AMF;
- and
- returning to the new AMF a subscription permanent identifier (SUPI) of the UE and an indication that a registration request procedure is validated for integrity protection without including an entire UE context in response to determining that the interface cannot be relocated to the new AMF.
One or more processors of an Access and Mobility Function (AMF) configured to perform operations, the operations comprising:
- receiving a registration request from a user equipment (UE) registered to an old AMF with a first access type;
- sending a request to the old AMF for a UE context transfer, wherein the UE context transfer request includes an indication of a second access type for the UE with which to register with the AMF;
- and
- receiving from the old AMF a subscription permanent identifier (SUPI) of the UE and an indication that a registration request procedure is validated for integrity protection without including an entire UE context.
A method of an Access and Mobility Function (AMF) comprising:
- receiving a request from a new AMF for a user equipment (UE) context transfer for a UE registered to the AMF a first access type, wherein the request includes an indication of a second access type for the UE via which to register with the new AMF;
- determining that an interface cannot be relocated to the new AMF;
- and
- returning to the new AMF a subscription permanent identifier (SUPI) of the UE and an indication that a registration request procedure is validated for integrity protection without including an entire UE context in response to determining that the interface cannot be relocated to the new AMF.
A method of an Access and Mobility Function (AMF) configured to perform operations comprising:
- receiving a registration request from a user equipment (UE) registered to an old AMF via a first access type;
- sending a request to the old AMF for a UE context transfer, wherein the UE context transfer request includes an indication of a second access type for the UE with which to register with the AMF;
- and
- receiving from the old AMF a subscription permanent identifier (SUPI) of the UE and an indication that a registration request procedure is validated for integrity protection without including an entire UE context.
