the first body field includes at least one of the type information, the identity code information, or the identity, and

the second body field includes the response data.

8. The method of claim 3 , wherein if a terminal is in a connection state, the configuration information includes a resource allocation indicator indicating whether a resource for the transmission of the response message is allocated to the at least one terminal without receiving, from the at least one terminal, a request for the resource and time information indicating an allocation time of the resource.

9. The method of claim 8 , further comprising transmitting resource information indicating the allocated resource to the terminal,

wherein the response message is transmitted through the allocated resource.

10. The method of claim 8 , further comprising:

transmitting, to the at least one terminal, an uplink (UL) grant for allocating the resource based on the resource allocation indicator,

wherein the UL grant is transmitted without receiving, from the at least one terminal, the request when the resource allocation indicator indicates the UL grant is transmitted, to the at least one terminal, without receiving the request from the at least one terminal.

11. The method of claim 3 , further comprising:

receiving an RRC connection request message to request an RRC connection from a terminal;

transmitting an RRC connection configuration message including configuration information of a dedicated bearer configured between the terminal and the base station and a resource allocation indicator indicating whether a resource for the transmission of the response message has been allocated as a response to the RRC connection request message; and

transmitting resource information indicating the allocated resource to the terminal,

wherein the RRC connection request message includes a cause field indicating an RRC connection request for transmitting/receiving the data of a service, and

the response message is transmitted through the allocated resource.

12. The method of claim 3 , further comprising:

receiving a request message to request the transmission of the response message from a terminal; and

transmitting a response message including resource information for transmitting the response message to the terminal,

wherein the response message is transmitted based on the resource information.

13. The method of claim 12 , wherein the request message includes at least one of a transmission/reception indicator indicating whether the request message is a message for transmission, a dedicated bearer indicator indicating whether a transmission path of the response message is the dedicated bearer, identity code information indicating a response to the specific data, or type information indicating a type of response data.

14. The method of claim 1 , further comprising:

transmitting bearer support information indicating whether a dedicated bearer configured between a terminal and the base station is supported and support message type information indicating a type of message capable of being transmitted through the dedicated bearer in order to provide a service to the terminal; and

configuring the dedicated bearer with the terminal.

15. The method of claim 14 , wherein the configuring the dedicated bearer comprises:

receiving an RRC connection request message to request an RRC connection from the terminal; and

transmitting an RRC connection configuration message including configuration information of the dedicated bearer as a response to the RRC connection request message, and

wherein the RRC connection request message includes a cause field indicating an RRC connection request for transmitting/receiving the data of the service.

16. The method of claim 14 , wherein the configuring the dedicated bearer comprises:

transmitting an RRC connection reconfiguration message indicating configuration information of the dedicated bearer to the terminal; and

receiving an RRC connection reconfiguration complete message as a response to the RRC connection reconfiguration message.

17. The method of claim 1 , wherein the bearer information includes at least one of a bearer ID indicating the bearer, message filtering information indicating a message capable of being transmitted/received through the bearer, quality of service (QoS) information of the message capable of being transmitted/received through the bearer, or an address of the gateway connected through the bearer.

18. A method for establishing a bearer of a terminal for transmitting and receiving data in wireless communication system, the method comprising:

receiving, from a base station, configuration information including an indicator indicating whether response data of at least one terminal for the specific data is necessary, for transmitting specific data;

receiving the specific data based on the configuration information from the base station; and

transmitting a response message indicating the response data as a response to the specific data to the base station,

wherein the configuration information includes at least one of reception terminal information indicating the at least one terminal which will receive the specific data, transmission interval information indicating an interval in which the specific data is transmitted, transmission cycle information indicating a cycle in which the specific data is transmitted, type information indicating a type of the specific data, an identity for identifying a resource region of the specific data, resource region information indicating a resource region in which the specific data is included, or identity code information for identifying the specific data, and

wherein a specific bearer is configured between the base station and a gateway if the indicator indicates that the response data is necessary.
