Abstract

A method and a device for setting priority of data transmission are provided. A terminal, which is set to transmit low priority data to a network, transmits a connection request to the network in order to transmit normal-priority data, and receives and stores priority information on data transmission from the network.

Claims

1. A method for transmitting normal priority data at a terminal configured to transmit low priority data to a network, the method comprising:

transmitting a connection request to the network;

receiving priority information for data transmission from the network; and

storing the received priority information.

2. The method of claim 1, wherein the priority information is determined per priority (PDN) connection between the terminal and the network, per an evolved packet system (EPS) bearer, or per internet protocol (IP) flow.

3. The method of claim 1, wherein the priority information is received from an mobility management entity (MME) of the network.

4. The method of claim 3, wherein the priority information is acquired from at least one of subscriber information of the terminal which is stored in a home subscriber server (HSS) of the network and an operator policy stored in the MME.

5. The method of claim 1, further comprising transmitting data to the network based on the stored priority information.

7. The method of claim 1, further comprising:

transmitting a change request for changing a low priority connection configured to transmit the low priority data to the network for a normal priority connection capable of transmitting the normal priority data;

receiving a response indicating whether to allow the change to the normal priority connection from the network; and

transmitting, when the response is an accept response, the normal priority data through the normal priority connection.

8. The method of claim 7, further comprising performing, when the response is a reject response, an operation depending on content of the reject response,

wherein the operation dependent on the content of the reject response is one of detaching from the network and maintaining the low priority connection.

6. The method of claim further comprising:

checking the priority information corresponding to the data based on the stored priority information; and

transmitting, when the priority data corresponding to the data is the normal priority, the connection request indicating that the data is the normal priority data.

9. A method for processing normal priority data received from a terminal configured to transmit low priority data, the method comprising:

receiving a connection request from the terminal;

checking priority information on data transmission of the terminal based on one of subscriber information of the terminal and an operator policy in response to the connection request; and

transmitting the checked priority information to the terminal.

10. The method of claim 9, wherein the priority information is acquired from subscriber information of the terminal which is stored in an HSS.

11. The method of claim 9, wherein the priority information is determined per priority data network (PDN) connection between the terminal and the network, per an evolved packet system (EPS) bearer, or per internet (IP) flow.

12. The method of claim 9, further comprising:

receiving a connection request indicating the normal priority data from the terminal;

checking whether the priority information included in the connection request matches at least one of subscriber information of the terminal and the operator policy; and

transmitting, when the priority information included in the connection request matches at least one of the subscriber information and the operator policy, an accept response to the terminal in response to the connection request.

13. The method of claim 9, further comprising:

receiving a connection request for changing a low priority connection configured for transmitting low priority data for a normal priority connection capable of transmitting the normal priority data;

determining whether the change to the normal priority connection is allowable based on a change information of a user equipment (UE) which is stored previously; and

transmitting, when the change to the normal priority connection, an accept response to the terminal.

14. The method of claim 13, further comprising transmitting a normal priority indicator indicating the normal priority connection to a priority data network serving gateway (PGW), which stores the normal priority indicator.

15. The method of claim 13, further comprising transmitting, when the change to the normal priority connection is impossible, a reject response to the terminal,

wherein the reject response includes content indicating an operation of the terminal to be taken depending on the reject response.

16. The method of claim 13, wherein the change information comprises at least one of whether the terminal is capable of transmitting the normal priority data, whether an access priority network (APN) delivering the connection request of the terminal supports the low priority connection, and whether the APN supports changing the low priority connection for the normal priority connection.

17. The method of claim 13, wherein the method is performed by an mobility management entity (MME).

18. An apparatus for transmitting normal priority data, the apparatus being included in a terminal configured to transmit low priority data to a network, the apparatus comprising:

a radio communication unit configured to transmit and receive messages and data to and from the network;

a control unit configured to control transmitting a connection request to the network and receiving priority information for data transmission from the network; and

a storage unit configured to store the received priority information.

19. The apparatus of claim 18, wherein the priority information is determined priority data network (PDN) connection between the terminal and the network, per an evolved packet system (EPS) bearer, or per internet protocol (IP) flow.

20. The apparatus of claim 18, wherein the priority information is received from an mobility management entity (MME) of the network.

21. The apparatus of claim 20, wherein the priority information is acquired from at least one of subscriber information of the terminal which is stored in an a home subscriber server (HSS) of the network and an operator policy stored in the mobility management entity (MME).

22. The apparatus of claim 18, wherein the control unit is configured to control transmitting data to the network based on the stored priority information.

23. The apparatus of claim 22, wherein the control unit is configured to check the priority information corresponding to the data based on the stored priority information and control transmitting, when the priority data corresponding to the data is the normal priority.

The apparatus of claim 18, wherein the control unit is configured to control transmitting a change request for changing a low priority connection configured to transmit the low priority data to the network for a normal priority connection capable of transmitting the normal priority data, receiving a response indicating whether to allow the change to the normal priority connection from the network, and transmitting, when the response is an accept response, the normal priority data through the normal priority connection.

25. The apparatus of claim 24, wherein the control unit is configured to control the performing of an operation depending on content of the reject response, when the response is a reject response,
