Abstract

A method and system for generating an allowed list based on regions for a wireless terminal are disclosed. The method generates an allowed list based on regions to control network access of a stationary wireless terminal, and includes: sending, by the wireless terminal, an attach request to a network; creating, by the network, an allowed list that contains information on regions in which the wireless terminal is permitted to access the network; and controlling, by the network, network access of the wireless terminal on the basis of the allowed list. Hence, the allowed list, which stores information regarding regions in which the MTC terminal 110 is permitted to access the network, may be dynamically created by the terminal or the MME.

Claims

1. A method for generating an allowed list based on regions to control network access of a stationary wireless terminal, comprising:

sending, by the wireless terminal, an attach request to a network;

creating, by the network, an allowed list that contains information on regions in which the wireless terminal is permitted to access the network; and

controlling, by the network, network access of the wireless terminal on the basis of the allowed list.

2. The method of claim 1, wherein sending an attach request to a network comprises:

collecting, by the wireless terminal, information on available cells for a preset time and creating a cell list;

sending, by the wireless terminal, an attach request containing the cell list to a base station (eNB) of the network; and

sending, by the base station, an initial UE message containing the cell list to a mobility management entity (MME) of the network.

3. The method of claim 2, wherein the initial UE message further comprises a cell identifier of the base station.

4. The method of claim 3, wherein creating an allowed list comprises:

receiving, by the MME, an initialized allowed list from a home subscriber server (HSS) of the network;

adding, by the MME, the cell identifier of the base station having transmitted the initial UE message and cell identifiers contained in the cell list to the initialized allowed list up to a preset number of cell identifiers; and

sending, by the MME, the allowed list to the wireless terminal.

5. The method of claim 4, wherein, in adding the cell identifier, the cell identifier of the base station having transmitted the initial UE message is added first to the allowed list.

6. The method of claim 1, further comprising:

sending, by the wireless terminal, a tracking area update request to the network; and

updating, upon reception of the tracking area update request by the network, the allowed list according to a given update rule.

7. The method of claim 1, further comprising initializing, when the allowed list of the network is initialized, by the network, the allowed list of the wireless terminal.

8. The method of claim 1, wherein creating an allowed list comprises:

receiving, upon reception of an initial UE message from a base station, by an MME of the network, an initialized allowed list from an HSS of the network; and

adding, by the MME, the cell identifier of the base station having transmitted the initial UE message to the initialized allowed list.

9. A system for generating an allowed list based on regions to control network access, comprising:

a stationary wireless terminal sending an attach request; and

a network creating, upon reception of the attach request, an allowed list that contains information on regions at which the wireless terminal is permitted to access the network, and controlling network access of the wireless terminal on the basis of the allowed list.

10. The system of claim 9, wherein the wireless terminal collects information on available cells for a preset time to create a cell list and sends an attach request containing the cell list.

11. The system of claim 10, wherein the network comprises a base station (eNB) and a mobility management entity (MME), and wherein the base station receives the attach request and sends an initial UE message containing the cell list to the MME.

12. The system of claim 11, wherein the initial UE message further comprises a cell identifier of the base station.

13. The system of claim 12, wherein the MME receives an initialized allowed list from a home subscriber server (HSS), and adds the cell identifier of the base station having transmitted the initial UE message and cell identifiers contained in the cell list to the initialized allowed list up to a preset number of cell identifiers.

14. The system of claim 13, wherein the MME adds the cell identifier of the base station having transmitted the initial UE message first to the allowed list.

15. The system of claim 9, wherein the wireless terminal sends a tracking area update request to the network and the network updates, upon reception of the tracking area update request, the allowed list according to a given update rule.

16. The system of claim 9, wherein, when the allowed list of the network is initialized, the network initializes the allowed list of the wireless terminal.

17. The system of claim 9, wherein the network comprises a base station (eNB) and a mobility management entity (MME), and wherein the MME receives, upon reception of an initial UE message from the base station, an initialized allowed list from an HSS, and adds the cell identifier of the base station having transmitted the initial UE message to the initialized allowed list.
