Abstract

A method for effectively transmitting and receiving access information between a terminal and a base station using a message separation for a RRC CONNECTION REQUEST message that may include: transmitting a random access preamble; receiving a random access response in response to the random access preamble, wherein the random access response includes information related to at least one allocated radio resource which will be used for transmitting the RRC CONNECTION REQUEST message; determining at least one required radio resource for transmitting the RRC CONNECTION REQUEST message; generating the RRC CONNECTION REQUEST message by considering a characteristic of at least one among the at least one allocated radio resource and the determined at least one required radio resource, and transmitting the generated RRC CONNECTION REQUEST message.

Claims

1. A method of communicating data in a wireless communications system, the method comprising:

transmitting a random access preamble;

receiving a random access response in response to the random access preamble,

wherein the random access response includes information related to at least one allocated radio resource which will be used for transmitting a next scheduled data;

determining at least one required radio resource for transmitting the next scheduled data; and

generating the next scheduled data by considering at least one among the at least one allocated radio resource and the determined at least one required radio resource.

2. The method of claim 1, wherein the next scheduled data is a RRC CONNECTION REQUEST message.

3. The method of claim 1, wherein the next scheduled data includes a NonAccess Stratum (NAS) message.

4. The method of claim 3, wherein the NAS message is at least one of Attach Request, Routing Area Update Request, Detach Request, and Service Request.

5. The method of claim 1, wherein the generating the next scheduled data comprises comparing the determined at least one required radio resource with the at least one allocated radio resource.

6. The method of claim 5, further comprising:

transmitting the next scheduled data using the at least one allocated radio resource when the at least one allocated radio resource is equal or greater than the determined at least one required radio resource.

7. The method of claim 5, wherein the generating the next scheduled data further comprises separating the next scheduled data into two or more data groups when the at least one allocated radio resource is below or smaller than the determined at least one required radio resource.

8. The method of claim 7, further comprising:

transmitting each data group separately.

9. The method of claim 7, wherein the next scheduled data of a first data group is related to information for a connection between a terminal and a base station, and the next scheduled data of a second data group is related to information for a connection between the base station and a Mobility Management Entity (MME).

10. The method of claim 7, wherein a Radio Resource Control (RRC) signal from a base station to a terminal designates what information of the next scheduled data should be included in which data group.

11. The method of claim 10, wherein the information related to what information of the next scheduled data should be included in which data group is determined by an amount of data which will be transmitted from the terminal and/or an amount of allocated radio resource in the random access response.

12. The method of claim 11, wherein the RRC signal is either system information or a paging message.

13. The method of claim 7, wherein each separated data group includes an identity for indicating a type of information.

14. The method of claim 1, wherein the determined at least one allocated or the at least one required radio resource is defined by one or more bit numbers or any parameters that represent radio resources.

15. The method of claim 1, wherein the generating the next scheduled data comprises checking the determined at least one required radio resource with a threshold value.

16. The method of claim 15, wherein the generating the next scheduled data further comprises comparing the determined at least one required radio resource with the at least one allocated radio resource when the determined at least one required radio resource is below or smaller the threshold value.

17. A method of communicating data in a wireless communications system, the method comprising:

receiving a random access preamble;

transmitting a random access response in response to the received the random access preamble, wherein the random access response includes information related to at least one allocated radio resource for transmitting a next scheduled data by a terminal; and

receiving the next scheduled data from the terminal,

wherein the terminal determines at least one required radio resource for transmitting the next scheduled data, and

wherein the next scheduled data is generated by considering at least one among the at least one allocated radio resource and the determined at least one required radio resource by the terminal before transmitting the next scheduled data.

18. The method of claim 17, wherein the next scheduled data is a RRC CONNECTION REQUEST message.

19. The method of claim 18, further comprising

determining whether the next scheduled data contains any NAS message by checking an identity included in the next scheduled data.

20. The method of claim 19, wherein the identity is used for indicating information of which group is included in the next scheduled data.

21. The method of claim 17, wherein the determined at least one required radio resource is compared with the at least one allocated radio resource for generating the next scheduled data by the terminal.

22. The method of claim 21, wherein the next scheduled data is separated into two or more data groups when the at least one allocated radio resource is below or smaller than the determined at least one required radio resource, and each data group is separately received.

23. The method of claim 22, wherein the next scheduled data of a first data group is related to information for a connection between the terminal and a base station, and the next scheduled data of a second data group is related to information for a connection between the base station and a Mobility Management Entity (MME).

24. The method of claim 22, further comprising:

transmitting a Radio Resource Control (RRC) signal in order to designate what information of the next scheduled data should be included in which data group.

25. The method of claim 24, wherein the RRC signal is either system information or a paging message.

27. The method of claim 17, wherein the determined at least one required radio resource is compared with a threshold value, and the determined at least one required radio resource is compared with the at least one allocated radio resource for generating the next scheduled data by the terminal if the determined at least one required radio resource is below or smaller the threshold value.

28. The method of claim 17, wherein the determined at least one allocated or the at least one required radio resource is defined by one or more bit numbers or any parameters that represent radio resources.

26. The method of 22, wherein each separated data group includes an identity for indicating a type of information.

29. A mobile terminal for communicating data in a wireless communications system, the mobile terminal comprising:

a transceiver adapted to transmit or receive the data;

a memory adapted to store the data transmitted or received via the transceiver or from an external source; and

a processor cooperating with the transceiver and the memory and adapted to perform the steps of,

transmitting a random access preamble;

receiving a random access response in response to the random access preamble,

wherein the random access response includes information related to at least one allocated radio resource which will be used for transmitting a next scheduled data;

determining at least one required radio resource for transmitting the next scheduled data; and

generating the next scheduled data by considering at least one among the at least one allocated radio resource and the determined at least one required radio resource.
