Abstract
One disclosure of the present specification provides a method performed by a terminal that performs registration in a non-3rd generation partnership project (3GPP) access. According to the method, the terminal may receive a rejection message including a value of a back-off timer. In addition, the terminal may determine a value of a non-3GPP de-registration timer on the basis of the value of the back-off timer. In this case, the value of the non-3GPP de-registration timer may be determined to be greater than the value of the back-off timer.
Claims9
A method performed by a user equipment which has performed a registration in a non-3rd generation partnership project (3GPP) access, the method comprising:
- receiving, from an Access and Mobility management Function (AMF) node, a registration reject message including a value of a back-off timer;
- determining a value of a non-3GPP de-registration timer based on the value of the back-off timer,
- wherein the value of the non-3GPP de-registration timer is determined to be 4 minutes greater than the value of the back-off timer;
- running the non-3GPP de-registration timer based on the determined value based on that a signaling connection over the non-3GPP access is released,
- wherein the value of the non-3GPP de-registration timer is less than a value of a non-3GPP implicit de-registration timer which is run by the AMF node.
A user equipment (UE) which has performed a registration in a non-3rd generation partnership project (3GPP) access, the UE comprising:
- a transceiver and a processor,
- wherein the processor is configured to:
- control the transceiver to receive a registration reject message including a value of a back-off timer from an Access and Mobility management Function (AMF) node;
- determine a value of a non-3GPP de-registration timer based on the value of the back-off timer,
- wherein the value of the non-3GPP de-registration timer is determined to be 4 minutes greater than the value of the back-off timer;
- and
- run the non-3GPP de-registration timer based on the determined value based on that a signaling connection over the non-3GPP access is released,
- wherein the value of the non-3GPP de-registration timer is less than a value of a non-3GPP implicit de-registration timer which is run by the AMF node.
A non-transitory computer-readable medium having stored thereon a plurality of instructions, which, when executed by a processor of a user equipment, cause the user equipment to perform operations, the operations comprises,
- performing a registration in a non-3rd generation partnership project (3GPP) access;
- receiving a registration reject message including a value of a back-off timer from an Access and Mobility management Function (AMF) node;
- determining a value of a non-3GPP de-registration timer based on the value of the back-off timer,
- wherein the value of the non-3GPP de-registration timer is determined to be 4 minutes greater than the value of the back-off timer;
- and
- running the non-3GPP de-registration timer based on the determined value based on that a signaling connection over the non-3GPP access is released,
- wherein the value of the non-3GPP de-registration timer is less than a value of a non-3GPP implicit de-registration timer which is run by the AMF node.
