Abstract

Method for controlling a traffic load in a mobile communication system, including the steps of (1) providing dynamic priority group numbers(P_DPROTG) which will be made available depending on a traffic load to each terminal which has a predefined priority in a cell, the dynamic priority group numbers(P_DPROTG) being provided in a system, (2) transmitting a permitted dynamic priority group number(P-DPROTG) from the system to each terminal in fixed time intervals depending on the traffic load, (3) each terminal calculating a dynamic priority(DRPOT) of the terminal, (4) each terminal comparing the P_DPROTG from the system and the DPROT calculated by the terminal itself, to determine a dynamic priority group number to which the terminal belongs, and (5) according to a result of the determination in the step (4), each terminal determining, and executing a user data transmission to the system.

Claims

1. A method for controlling a traffic load in a mobile communication system, comprising the steps of:

2. A method as claimed in claim 1, wherein the step (5) includes the steps of,

3. A method as claimed in claim 2, further including the steps of;

4. The method as claimed in claim 1, further comprising the terminal transmitting the user data to the system without comparing the DPROT of the terminal to the P_DPROTG when a dynamic priority group (DRPOTG) of the P_DPROTG from the system is set to “0”.

5. A method as claimed in claim 1, wherein the DPROT of the terminal is calculated with an equation, below;

DPROT=

K(

WQ+SQ)/

SQ,

Where, DPROT denotes a dynamic priority, WQ denotes a waited quantity, SQ denotes a served quantity, WQ+SQ denotes data quantity required through an SCRM, and K is a coefficient based on a predefined priority.

6. A method as claimed in claim 1, wherein the fixed time interval is 20 ms.

7. A method as claimed in claim 1, wherein each of the terminals is a terminal which has an active packet data service state.

8. A method for controlling a traffic load in a mobile communication system, comprising:

9. The method as claimed in claim 8, further comprising transmitting a number of dynamic priority groups currently set up in the system and a dynamic priority boundary of each group from the system to each terminal in an overhead message through one of a paging channel and a common channel.

10. The method as claimed in claim 9, wherein the boundary of each group is a maximum value, and a dynamic priority boundary of the group ranges from a value that is one (1) greater than a maximum value of a group one stage lower than the group in question to the maximum value of the group in question.

11. The method as claimed in claim 8, wherein the step (7) further comprises: transmitting user data to the system when a level of the DPROT is greater than or equal to a level of the P_DPROTG as a result of the determination, and

12. The method as claimed in claim 11, further comprising additionally transmitting a field X_STOP), informing a transmission OK of the user data of the blocked terminal, from the blocked terminal to the system through the F_FCH.

13. The method as claimed in claim 12, wherein the field (TX_STOP) is a 1 bit signal added to all frames transmitting and receiving through the R_FCH.

14. The method as claimed in claim 11, further comprising:

15. The method as claimed in claim 14, further comprising transmitting the updated P_DPROTG from the system in fixed time intervals through the F-FCH after the blocked terminal transmits the user data to the system through the R_FCH.

16. The method as claimed in claim 15, wherein the fixed time interval is 20 ms.

17. The method as claimed in claim 8, further comprising transmitting the user data from the terminal to the system without comparing the DPROT of the terminal to the P_DPROTG when a dynamic priority group (DPROTG) of the P_DPROTG from the system is set to “0”.

18. The method as claimed in claim 8, wherein the DPROT of the terminal is calculated with an equation,

DPROT=

K(

WQ+SQ)/

SQ,

where, DPROT denotes a dynamic priority, WQ denotes a waited quantity, SQ denotes a served quantity, WQ+SQ denotes data quantity required through an SCRM, and K is a coefficient based on a predefined priority.

19. The method as claimed in claim 8, wherein the fixed time interval is 20 ms.

20. The method as claimed in claim 8, wherein each of the terminals is a terminal which has an active packet data service state.

21. A method of controlling traffic in a mobile communication system, comprising the steps of:

22. The method of claim 21, wherein data is transmitted to the base station when the calculated dynamic priority is greater than or equal to the permitted dynamic priority group number, and wherein transmissions are temporarily suspended to the base station if the dynamic priority is less than the permitted dynamic priority group member.

23. The method of claim 21, wherein the base station transmits the permitted dynamic priority group number to the mobile terminal when the traffic load on the communication channel exceeds a prescribed level.

24. The method of claim 21, wherein a priority of the mobile terminal is predefined in the mobile communication system.

25. A method of controlling traffic a communication system, comprising the steps of:

26. The method of claim 25, wherein the priority level of each mobile terminal is set by the corresponding mobile terminal.
