Abstract

A communication technique that combines a 5G communication system for supporting a data rate that is higher than that of a beyond 4G system with IoT technology, and a system thereof are provided. The technique may be applied to intelligent services on the basis of 5G communication technology and IoT related technology, such as smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, etc. A method of performing access deregistration by a user equipment (UE) and an apparatus therefor are provided. The method includes, when the UE is registered on both 3rd generation partnership project (3GPP) access and non-3GPP access, transmitting, to an access and mobility management function (AMF), a deregistration request message to deregister the non-3GPP access over the 3GPP access, and receiving, from the AMF, a deregistration accept message corresponding to the deregistration request message over the 3GPP access.

Claims (50)

1. A method performed by a terminal, the method comprising:

identifying whether the terminal is registered on both 3rd generation partnership project (3GPP) access and non-3GPP access and the terminal has no connection for the non-3GPP access; and

performing a deregistration procedure over the 3GPP access, in case that the terminal is registered on both the 3GPP access and the non-3GPP access and the terminal has no connection for the non-3GPP access,

wherein the performing of the deregistration procedure further comprises:

transmitting, to an access and mobility management function (AMF) serving the 3GPP access and the non-3GPP access, a deregistration request message to deregister the terminal for the non-3GPP access, over the 3GPP access,; and

receiving, from the AMF, a deregistration accept message corresponding to the deregistration request message over the 3GPP access, and

wherein all protocol data unit (PDU) sessions associated with the non-3GPP access are released in the deregistration procedure.

2. The method of claim 1 , wherein a temporary identifier is assigned to the terminal during a registration procedure over the non-3GPP access in a public land mobile network (PLMN), the assigned temporary identifier corresponding to a temporary identifier assigned during a registration procedure over the 3GPP access in a same PLMN.

3. The method of claim 2 , wherein the deregistration procedure is performed after assigning the temporary identifier to the terminal during the registration procedure over the non-3GPP access.

4. The method of claim 1 , wherein the identifying further comprises:

identifying whether the terminal is out of a coverage for the non-3GPP access; and

determining that the terminal has no connection for the non-3GPP access according to the identification that the terminal is out of the coverage for the non-3GPP access.

5. The method of claim 1 , wherein separate registration management for the 3GPP access and the non-3GPP access is provided by the AMF.

6. A method performed by an access and mobility management function (AMF) serving 3rd generation partnership project (3GPP) access and non-3GPP access, the method comprising:

receiving, from a terminal, a deregistration request message to deregister the terminal for the non-3GPP access over the 3GPP access; and

transmitting, to the terminal, a deregistration accept message corresponding to the deregistration request message over the 3GPP access,

wherein the deregistration request message is received based on a deregistration procedure over the 3GPP access being performed, in case that the terminal is registered on both the 3GPP access and the non-3GPP access and the terminal has no connection for the non-3GPP access, and

wherein all protocol data unit (PDU) sessions associated with the non-3GPP access are released in the deregistration procedure.

7. The method of claim 6 , further comprising:

assigning a temporary identifier to the terminal during a registration procedure over the non-3GPP access in a public land mobile network (PLMN), the assigned temporary identifier corresponding to a temporary identifier assigned during a registration procedure over the 3GPP access in a same PLMN.

8. The method of claim 7 , wherein the deregistration procedure is performed after assigning the temporary identifier to the terminal during the registration procedure over the non-3GPP access.

9. The method of claim 6 , wherein separate registration management for the 3GPP access and the non-3GPP access is provided by the AMF.

10. The method of claim 6 , wherein the terminal has no connection for the non-3GPP access in a case that the terminal is out of coverage for the non-3GPP access.

11. A terminal comprising:

a transceiver; and

a controller coupled with the transceiver and configured to control to:

identify whether the terminal is registered on both 3rd generation partnership project (3GPP) access and non-3GPP access and the terminal has no connection for the non-3GPP access, and

perform a deregistration procedure over the 3GPP access, in case that the terminal is registered on both the 3GPP access and the non-3GPP access and the terminal has no connection for the non-3GPP access,

wherein the controller, to perform the deregistration procedure over the 3GPP access, is further configured to:

transmit, to an access and mobility management function (AMF) serving the 3GPP access and the non-3GPP access, a deregistration request message to deregister the terminal for the non-3GPP access, over the 3GPP access, and

receive, from the AMF, a deregistration accept message corresponding to the deregistration request message over the 3GPP access, and

wherein all protocol data unit (PDU) sessions associated with the non-3GPP access are released in the deregistration procedure.

12. The terminal of claim 11 , wherein a temporary identifier is assigned to the terminal during a registration procedure over the non-3GPP access in a public land mobile network (PLMN), the assigned temporary identifier corresponding to a temporary identifier assigned during a registration procedure over the 3GPP access in a same PLMN.

13. The terminal of claim 12 , wherein the deregistration procedure is performed after assigning the temporary identifier to the terminal during the registration procedure over the non-3GPP access.

14. The terminal of claim 11 , wherein the controller is further configured to:

identify whether the terminal is out of a coverage for the non-3GPP access, and

determine that the terminal has no connection for the non-3GPP access according to the identification that the terminal is out of the coverage for the non- 3 GPP access.

15. The terminal of claim 11 , wherein separate registration management for the 3GPP access and the non-3GPP access is provided by the AMF.

16. An access and mobility management function (AMF) serving 3rd generation partnership project (3GPP) access and non-3GPP access, the AMF comprising:

a transceiver; and

a controller coupled with the transceiver and configured to control to:

receive, from a terminal, a deregistration request message to deregister the terminal for the non-3GPP access over the 3GPP access, and

transmit, to the terminal, a deregistration accept message corresponding to the deregistration request message over the 3GPP access,

wherein the deregistration request message is received based on a deregistration procedure over the 3GPP access being performed, in case that the terminal is registered on both the 3GPP access and the non-3GPP access and the terminal has no connection for the non-3GPP access, and

wherein all protocol data unit (PDU) sessions associated with the non-3GPP access are released in the deregistration procedure.

17. The AMF of claim 16 , wherein the controller is further configured to:

assign a temporary identifier to the terminal during a registration procedure over the non-3GPP access in a public land mobile network (PLMN), the assigned temporary identifier corresponding to a temporary identifier assigned during a registration procedure over the 3GPP access in a same PLMN.

18. The AMF of claim 17 , wherein the deregistration procedure is performed after assigning the temporary identifier to the terminal during the registration procedure over the non-3GPP access.
