Abstract

Disclosed is a method and terminal for performing an attach procedure, wherein an attach request message including an APN information request field requesting a notification of an APN which provides sponsored connectivity is transmitted to a network entity, and when an attach reject message including information indicating that the sponsored connectivity cannot be supported and information for a new attach procedure is received, a new attach request message is transmitted to another network entity on the basis of cell information included in the information for a new attach procedure.

Claims

1. A method of performing an attach procedure by a user equipment (UE) in a wireless communication system, the method comprising:

transmitting an attach request message comprising an access point name (APN) information request field to a network entity to request the network entity to inform the UE of an APN providing sponsored connectivity;

receiving an attach reject message comprising information indicating that the sponsored connectivity is not supported and information for a new attach procedure from the network entity; and

transmitting a new attach request message to a different network entity based on cell information included in the information for the new attach procedure,

wherein the information for the new attach procedure comprises public land mobile network (PLMN) information related to the cell information,

wherein the transmitting the new attach request message comprises;

accessing a cell via a PLMN which is selected based on the PLMN information; and

transmitting the new attach request message based on system information received from the cell.

2. The method of claim 1, wherein the cell information included in the information for the new attach procedure comprises frequency band information of the cell and information on a cell ID,

wherein the cell is capable of immediately providing a service to the UE.

3. The method of claim 1, when an attach accept message comprising information indicating that the sponsored connectivity is supported is received from the network entity, further comprising generating a packet data network (PDN) connection based on the attach accept message.

4. The method of claim 3, wherein the attach accept message comprises a list of APNs where the UE is able to generate sponsored connectivity and APN configuration information related to APNs contained in the list of APNs and wherein the generating the PDN connection transmits a PDN connectivity request message to an APN selected from the list of APNs.

5. The method of claim 4, wherein the APN configuration information comprises at least one selected from the group consisting of identification information of a service mapped to the APNs, category information of the service mapped to the APNs, information on an IP flow or a server connected with the APNs, information on duration of sponsored connectivity supported by the APNs, and information on a condition of the sponsored connectivity supported by the APNs.

6. The method of claim 4, wherein the UE transmits a data packet, which is permitted to be transmitted via the PDN connection, to a network only.

7. The method of claim 1, wherein the sponsored connectivity supports a data communication without a charge for the UE.

8. A user equipment (UE) performing an attach procedure in a wireless communication system, the UE comprising:

a transmitter;

a receiver; and

a processor configured to operate in a manner of being connected with the transmitter and the receiver,

wherein the processor;

transmits an attach request message comprising an access point name (APN) information request field to a network entity to request the network entity to inform the UE of an APN providing sponsored connectivity;

receives an attach reject message comprising information indicating that the sponsored connectivity is not supported and information for a new attach procedure from the network entity; and

transmits a new attach request message to a different network entity based on cell information included in the information for the new attach procedure,

wherein the information for the new attach procedure comprises public land mobile network (PLMN) information related to the cell information, and

wherein the processor accesses a cell via a PLMN which is selected based on the PLMN information and transmits the new attach request message based on system information received from the cell.

9. The UE of claim 8, wherein the cell information included in the information for the new attach procedure comprises frequency band information of the cell and information on a cell ID, and wherein the cell is capable of immediately providing a service to the UE.

10. The UE of claim 8, wherein when an attach accept message containing information indicating that the sponsored connectivity is supported is received from the network entity, the processor generates a packet data network (PDN) connection based on the attach accept message.

11. The UE of claim 10, wherein the attach accept message comprises a list of APNs where the UE is able to generate sponsored connectivity and APN configuration information related to APNs contained in the list of APNs and wherein the processor transmits a PDN connectivity request message to an APN selected from the list of APNs.

12. The UE of claim 11, wherein the APN configuration information comprises at least one selected from the group consisting of identification information of a service mapped to the APNs, category information of the service mapped to the APNs, information on an IP flow or a server connected with the APNs, information on duration of sponsored connectivity supported by the APNs, and information on a condition of the sponsored connectivity supported by the APNs.

13. The UE of claim 11, wherein the UE transmits a data packet, which is permitted to be transmitted via the PDN connection, to a network only.

14. The UE of claim 8, wherein the sponsored connectivity supports a data communication without a charge for the UE.
