Abstract

Disclosed is an operating method of a serving base station in wireless communication system. The method comprises obtaining delay-tolerance information with respect to user equipment, and operating based on the delay-tolerance information. The delay-tolerance information indicates whether the user equipment is a delay-tolerant user equipment (UE), which allows a service delay. Provided is a delay-tolerance information-based operating method of user equipment in a wireless communication system. The method comprises generating delay-tolerance information and transmitting delay-tolerance information to a network. The delay-tolerance information indicates whether the user equipment is a delay-tolerant user equipment (UE), which allows a service delay. The network is operated based on the delay-tolerance information.

Claims

1. An operating method of a serving base station in wireless communication system, the method comprising:

obtaining delay-tolerance information with respect to user equipment; and

operating based on the delay-tolerance information,

wherein the delay-tolerance information indicates whether the user equipment is a delay-tolerant user equipment (UE), which allows a service delay.

2. The method of claim 1, further comprising:

determining whether acquiring the delay tolerance information is required,

wherein the acquiring of the delay tolerance information is performed when it is determined that acquiring the delay tolerance information is required.

3. The method of claim 2, wherein when the serving base station verifies that a network overload environment occurs, it is determined that acquiring the delay tolerance information is required.

4. The method of claim 2, wherein:

when a notification that the network overload environment occurs is received from another network node, it is determined that acquiring the delay tolerance information is required.

5. The method of claim 1, wherein:

the acquiring of the delay tolerance information with respect to the UE includes

requesting the delay tolerance information to the UE, and

receiving the delay tolerance information from the UE as a response to the request.

6. The method of claim 1, wherein:

the acquiring of the delay tolerance information with respect to the UE includes

requesting the delay tolerance information to a mobility management entity (MME) managing the delay tolerance information, and

receiving the delay tolerance information from the MME as a response to the request.

7. The method of claim 6, wherein the delay tolerance information is updated through a network by the UE when a delay tolerance characteristic of the UE is changed.

8. The method of claim 1, wherein the operating based on the delay-tolerance information includes determining whether to hand over the UE based on the delay tolerance information.

9. The method of claim 1, wherein the operating based on the delay-tolerance information includes determining whether to release radio resource control (RRC) connection with the UE.

10. The method of claim 1, wherein:

the operating based on the delay-tolerance information includes

forwarding the delay tolerance information to a target base station for hand-over, and

whether to hand over the UE is determined by the target base station based on the delay tolerance information.

11. The method of claim 1, wherein when only a delay tolerant radio bearer is configured in the UE, the delay tolerance information indicates that the UE is the delay tolerant UE.

12. The method of claim 1, wherein when only a delay tolerance application is executed by the UE, the delay tolerance information indicates that the UE is the delay tolerant UE.

13. The method of claim 1, wherein When at least one is satisfied, of a case in which at least one delay tolerance radio bearer is configured in the UE and a case in which at least one delay tolerance application is configured by the UE, the delay tolerance information indicates that the UE is the delay tolerance UE.

14. The method of claim 13, wherein when other type of radio bearer is configured in the UE or other type of application is executed by the UE, the delay tolerance information further indicates at least one of the other type of radio bearer and the other type of application.

15. A wireless device that operates in wireless communication system, the device comprising:

a radio frequency (RF) unit which transmits or receives a radio signal; and

a processor which operates in functional association with the RF unit,

wherein the processor is configured to

obtain delay-tolerance information with respect to user equipment and

operate based on the delay-tolerance information, and

the delay-tolerance information indicates whether the user equipment is a delay-tolerant user equipment (UE), which allows a service delay.

16. A delay tolerance information based operating method performed by user equipment in wireless communication system, the method comprising:

generating delay tolerance information; and

transmitting the delay tolerance information to a network,

wherein the delay-tolerance information indicates whether the user equipment is a delay-tolerant user equipment (UE), which allows a service delay and

the network is operated based on the delay-tolerance information.

17. The method of claim 16, wherein:

the transmitting of the delay tolerance information to a network includes

receiving a delay tolerance information request from a serving base station fo the UE, and

transmitting the delay tolerance information to the serving base station as a response to the delay tolerance information request.

18. The method of claim 16, wherein:

the generating of the delay-tolerance information includes

when a delay tolerance characteristic of the UE is changed, updating the delay tolerance information to indicate whether the UE is the delay tolerant UE according to the delay tolerance characteristic of the UE, and

the transmitting of the delay tolerance information to a network includes

when the delay tolerance information is updated, transmitting the updated delay tolerance information to the network.
