Apparatus for reconstructing control message, apparatus for restoring control message, method of reconstructing control message, and method of restoring control message

A method of reconstructing a control message, the method comprising:

• classifying a plurality of first parameters in a control message on the basis of values of length fields defining the plurality of first parameters to generate group information;
• generating one or more index parameters including the number of first parameters included in each group and the values of the length fields of the first parameters included in each group, wherein one or more index parameters respectively corresponding to the groups;
• and
• reconstructing the control message on the basis of the group information and the index parameters.

An apparatus for restoring a control message, the apparatus comprising:

• an index parameter processing section that extracts values of first fields of one or more index parameters in a first control message and assigns first field values to one or more first parameters in a group corresponding to each index parameter;
• and
• a control message restoring section that deletes the index parameters and the first parameters in the first control message, and generates a second control message including the first parameters having the assigned first field values and second parameters in the first control message,
• wherein the group is a group which is generated by classifying a plurality of first parameters on the basis of values of length fields defining the plurality of first parameters.

A method of restoring a control message, the method comprising:

• determining whether or not a control message to be input is a first control message;
• if it is determined that the control message is the first control message, searching first field values of one or more one index parameters in the first control message;
• assigning the searched first field values to one or more first parameters in a group corresponding to each index parameter;
• and
• deleting the index parameters and the first parameters in the control message, and generating a second control message including the first parameters having the assigned first field values and second parameters in the first control message,
• wherein the group is a group which is generated by classifying a plurality of first parameters on the basis of values of length fields defining the plurality of first parameters.
