Abstract

An apparatus and method for managing a paging area may induce a paging area to be allocated to a User Equipment (UE). A paging area may be controlled to be updated upon an occurrence of an event and may reduce traffic congestion.

Claims

1. A method for managing a paging area, the method comprising:

determining a type of a currently allocated Tracking Area List (TAL) if a time period during which a User Equipment (UE) remains in a current Tracking Area (TA) exceeds a reference time period;

transmitting a Tracking Area Update (TAU) request to a network manager of a network if the type of the currently allocated TAL is determined to be a TAL for a fast-moving equipment; and

receiving a new TAL from the network manager.

2. The method of claim 1, wherein the new TAL is a TAL for a stationary equipment or a TAL for a slow-moving equipment.

3. The method of claim 1, wherein the new TAL is set based on the current TA and a time at which the TAU request is sent.

4. A method for managing a paging area, the method comprising:

measuring a mobility of a User Equipment (UE);

determining a type of a currently allocated Tracking Area List (TAL);

determining whether a current Tracking Area (TA) to which the UE belongs is changed;

notifying a network manager of a network of the measured mobility of the UE if the type of the currently allocated Tracking Area List (TAL) does not correspond to the measured mobility of the UE and if the current TA to which the UE belongs is determined to be changed; and

receiving a new TAL corresponding to the measured mobility of the UE from the network manager.

5. The method of claim 4, wherein the currently allocated TAL is a TAL for a fast-moving equipment, and the new TAL corresponding to the measured mobility of the UE is a TAL for a stationary equipment or a TAL for a slow-moving equipment.

6. The method of claim 4, wherein the currently allocated TAL is a TAL for a stationary equipment or slow-moving equipment, and the new TAL corresponding to the measured mobility of the UE is a TAL for a fast-moving equipment.

7. The method of claim 4, wherein the new TAL corresponding to the measured mobility of the UE is set based on the current TA and a time at which the network manager is notified of the measured mobility of the UE.

8. A method for managing a paging area, the method comprising:

measuring a mobility of a User Equipment (UE);

determining a type of a currently allocated Tracking Area List (TAL);

determining whether a paging message is received, if the type of the currently allocated TAL does not correspond to the measured mobility of the UE;

transmitting a paging response message containing the measured mobility of the UE to a network manager of a network, if the paging message is received; and

receiving a new TAL corresponding to the measured mobility of the UE from the network manager.

9. The method of claim 8, wherein a currently allocated TAL is a TAL for a fast-moving equipment, and the new TAL corresponding to the measured mobility of the UE is a TAL for a stationary equipment or a slow-moving equipment.

10. The method of claim 8, wherein a currently allocated TAL is a TAL for a stationary equipment or slow-moving equipment, and the new TAL corresponding to the measured mobility of the UE is a TAL for a fast-moving equipment.

11. The method of claim 8, wherein the TAL corresponding to the measured mobility of the UE is set based on a current Tracking Area (TA) and a time at which the network manager is notified of the measured mobility of the UE.

12. A method for managing a paging area, the method comprising:

measuring a mobility of a User Equipment (UE);

determining a type of a currently allocated Tracking Area List (TAL);

determining whether an access to a network occurs, if the type of the currently allocated TAL does not correspond to the measured mobility of the UE;

transmitting a service request message containing the measured mobility of the UE to a network manager of a network, if the access to the network occurs; and

receiving a new TAL corresponding to the measured mobility of the UE from the network manager.

13. The method of claim 12, wherein the currently allocated TAL is a TAL for a fast-moving equipment, and the new TAL corresponding to the measured mobility of the UE is a TAL for a stationary equipment or a slow-moving equipment.

14. The method of claim 12, wherein the currently allocated TAL is a TAL for a stationary equipment or slow-moving equipment, and the new TAL corresponding to the measured mobility of the UE is a TAL for a fast-moving equipment.

15. The method of claim 12, wherein the TAL corresponding to the measured mobility of the UE is set based on the current TA and a time at which the network manager is notified of the measured mobility of the UE.

16. An apparatus to manage a paging area, the apparatus comprising:

a mobility measuring unit to measure a mobility of a User Equipment (UE);

a storage unit to store an allocated Tracking Area List (TAL);

a controller to compare the measured mobility of the UE with a type of the allocated TAL and to control a Tracking Area Update (TAU) based on an event, the event occurring in the UE; and

a communication unit to transmit and/or receive a message used to perform the TAU.

17. The apparatus of claim 16, wherein, if the event occurs, the event comprising a time period during which the UE remains in a current Tracking Area (TA) exceeding a reference time period, the controller controls the UE to request the TAU if the type of the currently allocated TAL is determined to be a TAL for a fast-moving equipment.

18. The apparatus of claim 17, wherein, the event further comprises the controller determining a type of the allocated TAL and determining that the type of the currently allocated TAL is a TAL for a fast-moving equipment.

19. The apparatus of claim 16, wherein, if the event occurs, the event comprising the controller determining a change in the current TA, the controller controls the UE to notify the network manager of the measured mobility of the UE.

20. The apparatus of claim 19, wherein the event further comprises the controller determining that a type of a currently allocated TAL does not correspond to the measured mobility of the UE.

21. The apparatus of claim 16, wherein, if the event occurs, the event comprising receiving a paging message, the controller controls the UE to transmit a paging response message containing the measured mobility of the UE to the network manager.

22. The apparatus of claim 21, wherein the event further comprises the controller determining that a type of a currently allocated TAL does not correspond to the measured mobility of the UE.

23. The apparatus of claim 16, wherein, if the event occurs, the event comprising the controller determining whether an access to a network occurs;

the controller controls the UE to transmit a service request message containing the measured mobility of the UE to a network manager.

24. The apparatus of claim 23, wherein the event further comprises the controller determining that a type of a currently allocated TAL does not correspond to the measured mobility of the UE.

25. The apparatus of claim 16, wherein the communication unit receives a TAL corresponding to the measured mobility of the UE, and the TAL corresponding to the measured mobility of the UE is set based on the current TA and a time at which the TAU is requested.
