Description

Remote information retrieval and management method using short text service {METHOD OF REMOTE RETRIEVING AND MANAGING INFROMATION USING SHORT MESSAGE SERVICE}

The present invention relates to a method for remotely searching and managing information. In particular, the present invention provides a method for remotely searching and managing information using a receiving terminal capable of searching and managing information and a short message service (hereinafter, referred to as SMS). It is about a method.

SMS plays a role of transmitting text information and a lot of additional information. The SMS can receive and display or store contents transmitted from a transmitting terminal.

Currently, services provided by SMS in Korea include broadcasting teleservice, Korean PPP (PCS Paging Teleservice), Korean PMT (PCS Message Teleservice), voice mail notification service, and interactive teleservice. The characteristic of such a service is that a user can read a message received from a receiving terminal as a sentence and store it. In addition, an automatic call back dialing function is included, and the SMS terminal should be able to automatically dial a call if the reply phone number is included in the message delivered by the PPP, PMT, or the like.

There are three types of transport layer messages to be sent to the SMS, which are SMS point-to-point messages, SMS broadcast messages, and SMS response messages. These contents are shown in Table 1 below.

Message type Base station → terminal Terminal → Base Station SMS_MSG_TYPE SMS point-to-point message '00000000' SMS broadcast message × '00000001' SMS reply message '00000010'

The SMS_MSG_TYPE is one-byte information indicating the type of message and is an SMS transmission message identifier.

The format of the three messages is shown in Table 2 below.

field Length (bits) SMS_MSG_TYPE 8 Repeat the following parameter record more than once PARAMETER_ID 8 PARAMETER_LEN 8 PARAMETER DATA 8 × PARAMETER_LEN

Here, the PARAMETER_ID is an SMS transmission message parameter identifier. PARAMETER_LEN is an SMS message parameter length specifier, the content (field) of which is determined by the number of bytes of the length of an SMS message parameter not including the SMS transmission message parameter identifier and the SMS message parameter length specifier. Therefore, the length of the parameter data field (PARAMETER DATA) is eight times the length of the SMS message parameter. Various messages can be created according to the type of the parameter.

The transmitting terminal transmits an SMS message having the above format, and the receiving terminal determines the type of message through the SMS transmission message identifier and receives the message data through the subsequent set of parameters.

The terminal that can use the SMS includes not only a mobile communication terminal but also a wireless local loop (WLL) telephone. WLL telephones are not mobile, but not only can receive and display SMS information, but also has the ability to retrieve and manage the information as well as storing the information.

However, as described above, in the prior art, since SMS simply transmits data from one terminal to another terminal, it is impossible to control the receiving terminal and cannot handle commands such as information retrieval or information management. Therefore, even if a receiving terminal capable of searching and managing information is connected through a portable terminal, there is a problem in that the function of the receiving terminal cannot be used.

Accordingly, an object of the present invention for solving the above conventional problem is to send a command from a transmitting terminal to a receiving terminal using an SMS message, and the receiving terminal sends data in response to the command back to the transmitting terminal. By defining a, by using a wireless terminal, it is possible to remotely control a receiving terminal capable of searching and managing information, and to search and manage embedded information.
