Data transmission protocol using short message service
First Claim
1. A data sending protocol using a short message service, the data transmission protocol comprising the steps of:
- (a) inserting a data connection service identifier into a user data field;
(b) segmenting input message data into a plurality of short message data fields and inserting a segmented message data field, a field indicating the number of segmented short messages and a field indicating a current short message number, into the user data field;
(c) generating a short message field using the user data field; and
(d) transmitting the short message field.

Abstract
A data transmission protocol and apparatus using a short message service is provided. The data transmission protocol includes the steps of inserting a data connection service identifier into a user data field. Input message data is segmented into a plurality of short message data fields, and a segmented message data field, a field indicating the number of segmented short messages and a field indicating a current short message number, are inserted into the user data field. A short message field is generated using the user data field. The short message field is transmitted, thereby transmitting relatively large volume of data such as a simple picture and a rough sketch while using the short message service.

9. A data receiving protocol using short message service, the data receiving protocol comprising the steps of:
-
(a) checking a user data field of a delivery short message to extract a data connection service identifier;
when the data connection service identifier satisfies a predetermined condition, (b-1) translating data in a short message area among the user data field of the delivery message; and
(b-2) storing and connecting said translated data; and
when the data connection service identifier does not satisfy said predetermined condition, (c) performing an ordinary short message process. - View Dependent Claims (10, 11, 12, 13, 14, 15)

24. A data receiving apparatus using short message service, the apparatus comprising:
-
service identifying means for checking a user data field of a delivery short message to extract a data connection service identifier, outputting a control signal having a first logic level when the data connection service identifier satisfies a predetermined condition, and outputting said control signal having a second logic level when the data connection service identifier does not satisfy said predetermined condition;
short message field translating means for translating data in a short message area among the user data field of the delivery message, in response to the control signal having the first logic level;
short message storage/connection means for storing and connecting said translated data; and
ordinary short message processing means for performing an ordinary short message process in response to the control signal having the second logic level. - View Dependent Claims (25, 26, 27, 28, 29)
