In this case, the second item is not included in the second packet data in step S540 because the second item is not determined as the not-included item in step S530.

Next, the object Internet terminal 400 determines whether the values of the same items included in the two packet data are equal to each other (S520).

If it is determined in step S520 that the two items are identical in value, the object Internet terminal 400 may determine that the second item is not included in step S530.

For example, if the value of the first item and the value of the second item are the same, the object Internet terminal 400 may determine the second item as the not-included item.

In step S530, the object Internet terminal 400 may include an item flag item in which information on the not-included item is recorded, in the second packet data.

Here, the second packet data may be composed of a common header having a fixed inclusion item and a message body having a variable inclusion item, the item flag item may be included in the common header, and the second item may be included in the message body.

Next, the object Internet terminal 400 generates second packet data based on the remaining items of the candidate data excluding the items not including the items (S540).
