Method of transmitting user message, terminal and base station using the method

Abstract

When transmitting a user message, in a call setting period of a base station and a terminal and a radio connection state between a base station and a terminal, whenever a data transmittable channel resource is available, user messages of an amount corresponding to the available channel resource are transmitted. Therefore, user messages can be divided and transmitted according to an available channel in a call setting period.

What is claimed is: 
     
         1 . A method for transmitting a user message, the method comprising:
 confirming a size of a user message to be transmitted;   transmitting the user message through a radio channel of an available common resource when the size of the user message is lower than a predetermined minimum value;   transmitting the user message through a signaling radio bearer channel or a default data radio bearer channel when the size of the user message is greater than the minimum value and lower than a predetermined maximum value; and   transmitting the user message through a scheduled traffic channel when the size of the user message is greater than the maximum value.   
     
     
         2 . The method of  claim 1 , wherein in transmitting the user message through a radio channel of an available common resource, a terminal generates a message in which signaling information is coupled to the user message, includes an identifier representing that a user message is included in the coupled message, and transmits the coupled message. 
     
     
         3 . The method of  claim 1 , wherein in transmitting the user message through a signaling radio bearer channel or a default data radio bearer channel, when the user message should be encrypted, a terminal adds an identification parameter representing encryption to a corresponding user message and stores the user message in a buffer. 
     
     
         4 . The method of  claim 3 , wherein in transmitting the user message through a scheduled traffic channel, when an identification parameter representing encryption is set to the user message that is stored in the buffer, the terminal encrypts a corresponding user message and transmits the user message through a scheduled physical uplink shared channel (scheduled PUSCH). 
     
     
         5 . The method of  claim 1 , wherein in transmitting the user message through a scheduled traffic channel, until all user messages in a buffer are to be transmitted, a terminal repeats a process of transmitting the user message. 
     
     
         6 . The method of  claim 1 , wherein the radio channel of an available common resource is at least one of a common control channel and a paging channel. 
     
     
         7 . The method of  claim 1 , wherein the scheduled traffic channel is an allocated radio resource by a radio resource scheduler. 
     
     
         8 . The method of  claim 1 , wherein the minimum value and the maximum value vary according to the policy of a communication service provider.
