Abstract

The present disclosure relates to a communication method and system for converging a 5^th-Generation (5G) communication system for supporting higher data rates beyond a 4^th-Generation (4G) system with a technology for Internet of Things (IoT). The present application provides a method for light connection control for a User Equipment (UE), comprising the following steps of: acquiring, by a first radio access network node, light connection information for a UE; storing, by the first radio access network node, the acquired light connection Information; and, performing, by the first radio access network node, light connection control of the UE based on the acquired light connection information for the UE. By adopting the technical scheme disclosed in the present application, the signaling overhead can be saved, and the delay of the UE access network can be reduced.

Claims

1. A method of a user equipment (UE) in a wireless communication system, the method comprising:

receiving, from a first base station, a first control message including a UE identity associated with a UE context and a paging area configuration;

entering into an inactive state based on the first control message;

determining whether the UE in the inactive state moves out of a paging area based on the paging area configuration; and

transmitting, to a second base station, a second control message for a location area update of the UE, in case that the UE in the inactive state moves out of the paging area based on the paging area configuration.

2. The method of claim 1, wherein the paging area configuration includes at least one a list of a tracking area or a cell identity.

3. The method of claim 1, wherein the first control message includes paging cycling information.

4. The method of claim 1, further comprising:

receiving, from the second base station, a third control message in response to the second control message,

wherein the third control message includes the UE identity associated with the UE context and the paging area configuration.

5. The method of claim 1, further comprising:

transmitting, to the first base station, capability information including information indicating the UE supports the inactive state.

6. A method of a first base station in a wireless communication system, the method comprising:

receiving, from a core network, inactive state assistance information, the inactive state assistance information including at least one of discontinuous reception and transmission (DRX) information or mobility area information;

determining whether a user equipment (UE) is moved to an inactive state based on the inactive state assistance information; and

transmitting, to the UE, a control message including a UE identity associated with a UE context and a paging area configuration, in case that the UE is moved to the inactive state based on the inactive state assistance information.

7. The method according to claim 6, wherein the paging area configuration includes at least one a list of a tracking area or a cell identity.

8. The method of claim 6, wherein the control message further includes paging cycling information.

9. The method of claim 6, further comprising:

receiving, from a second base station, a request message for UE context retrieval; and

transmitting, to the second base station, a response message in response to the request message, the response message including the UE context.

10. The method of claim 6, further comprising:

receiving, from the UE, capability information including information indicating the UE supports the inactive state.

11. A method of a second base station in a wireless communication system, the method comprising:

receiving, from a user equipment (UE), a first control message for a location area update of the UE, in case that the UE in an inactive state moves out of a paging area based on a first paging area configuration; and

transmitting, to the UE, a second control message in response to the first control message,

wherein the second control message includes a UE identity associated with a UE context and a second paging area configuration.

12. The method of claim 11, wherein the second paging area configuration includes at least one a list of a tracking area or a cell identity.

13. The method of claim 11, wherein the second control message further includes paging cycling information.

14. The method of claim 11, further comprising:

transmitting, to a first base station, a request message for UE context retrieval; and

receiving, from the first base station, a response message in response to the request message, the response message including the UE context.

15. A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver; and

a controller coupled with the transceiver and configured to;

receive, from a first base station, a first control message including a UE identity associated with a UE context and a paging area configuration,

enter into an inactive state based on the first control message,

determine whether the UE in the inactive state moves out of a paging area based on the paging area configuration, and

transmit, to a second base station, a second control message for a location area update of the UE, in case that the UE in the inactive state moves out of the paging area based on the paging area configuration.

16. The UE of claim 15, wherein the paging area configuration includes at least one a list of a tracking area or a cell identity.

17. The UE of claim 15, wherein the first control message includes paging cycling information.

18. The UE of claim 15, wherein the controller is further configured to receive, from the second base station, a third control message in response to the second control message, and

wherein the third control message includes the UE identity associated with the UE context and the paging area configuration.

19. The UE of claim 15, wherein the controller is further configured to transmit, to the first base station, capability information including information indicating the UE supports the inactive state.

20. A first base station in a wireless communication system, the first base station comprising:

a transceiver; and
