The present invention provides a method for minimizing the number of messages transmitted during Information On Demand (IonD) in a mobile communication system and improving the efficiency of the network. The present invention relates to a recording medium capable of providing a unique identification number for each short message service (SMS) message transmitted, and a duration time stamp management method for recording and managing a maintenance period for each message. Method of minimizing the transmission message using the menu reconstruction method that enables the terminal to automatically identify the service structure and reorganize it when the change is made by using the information of the message and the transmitted message. And read by a computer recording a program for realizing the same. A recording medium.

In Code Division Multiple Access (CDMA), SMS can be easily implemented by using a unique data transmission property. The SMS has the same function as the two-way radio call, conceptually, allows simple text reception, voice mail notification, text transmission, etc., to provide customers with the desired information.

In the related art, an on-demand specialized SMS system has been used to provide an on-demand information service in a mobile communication network.

However, such on-demand mono-professional service system was provided with a simple server-oriented protocol due to the limitation of the mono-professional service function, and therefore, many SMS messages were required to provide the on-demand information service. This caused a serious load on the network, which required the expansion of many SMS MCs. In addition, there was a problem in that a user is provided with a slower and unstable service.

Looking at the configuration of the on-demand interactive SMS system to provide SMS as follows.

1 is a configuration diagram of a general on-demand single-service service system, which shows a configuration of a code division multiple access (CDMA) mobile communication system.

As shown in FIG. 1, a CDMA mobile communication system to which the present invention is applied includes a mobile station (MS) 11, a base station transceiver base system (BTS) 12, and a control station (BSC) (13), Mobile Switching Center (MSC) (14), Vistor Location Register (VLR) (15), Home Location Register (HLR) (16), Professional Service Message Center (SMS MC) 17, and a single server (SMS) server (18).

For the on-demand information service, a single specialized service message center 17 should be added to a general CDMA mobile communication system, and additionally, the single specialized service server 18 can be used to interwork with subscriber management and external systems. That is, in order to provide the on-demand information service, it is necessary to connect with an external IP that provides various types of information by interworking the single-service service server 18 having the on-demand information function to the single-service service message center 17. In addition, the mobile station 11 should route to the specialized service message center 17 to set up the specialized service environment.

The operation of each component of the CDMA mobile communication system for providing an on-demand information service using SMS is as follows.

The mobile station (MS) 11 is in the range of any base station 12, and the information of the mobile station 11 is transmitted to the exchange station 14 via the base station 12 and the control station 13 controlling it, The information transmitted from 14 is transmitted to the mobile station 11 via the base station 12 and the control station 13.

The mobile station 11 is a terminal that a user can carry and communicate with while moving. The mobile station 11 uses a forward channel for receiving text and a reverse channel for transmitting. At this time, all text information uses SMS, and when received, a Mobile Terminated (MT) SMS is used, and when used, a Mobile Originated (MO) SMS is used.

In this case, the MT SMS is a single-center service for the center originator. The IS-95 (EIA / TIA IS-95 standard, the communication protocol between the terminal and the base station of the broadband cellular network) and the IS-41C (EIA / TIA IS-) Mono-professional service message center in networks supporting 41C standard, inter-network interworking protocol of mobile wireless electric system), IS-637 (EIA / TIA IS-41C standard, mono-professional service protocol for spread spectrum cellular communication network) Shows a procedure of transmitting a single-service message to the terminal (11). In addition, the mobile outgoing (MO) SMS is a terminal outgoing single-specialized service, the terminal 11 in the network supported IS-95, IS-41C, IS-637 terminal 11 to the specialized service message center (17) Represents a procedure to transmit.

In general, a mobile communication system uses a data burst message of a paging channel of a CDMA mobile communication system upon reception, and data of a forward traffic channel when a user is busy. Send the text message as a burst message. In addition, a text burst message of an access channel is used to transmit a text message, and a data burst message of a reverse traffic channel is transmitted when a text message is in use.

The text message transmitted and received at the mobile station 11 is connected to the switching station 14 through the base station 12 and the control station 13 for high frequency signal processing and call processing.

The base station 12 connects the mobile station 11 to the control station 13, and includes a digital channel unit (DCU), a time / frequency control unit (TCU), and a radio frequency unit (RFU). : Radio Frequency Unit, and Global Positioning System (GPS).

In addition, the base station 12 performs a wired / wireless conversion function of communicating with the mobile station 11 over the air and communicating with the control station 13 by wire.

The control station 13 connects the base station 12 to the switching center 14 to coordinate the connection between the base stations 12 and performs a signal processing function for communication between the base station 12 and the switching station 14.

The exchange office 14 has a visitor location register 15 and processes the mobile communication subscriber call in association with the home location register 16 and the single specialized service message center 17. Then, it connects to the control station 13 to perform call setup and release functions of the mobile station 11, and performs various functions related to call processing and additional services.

The visitor location register 15 is a database that temporarily stores subscriber information related to the mobile station 11 while the mobile station 11 is in an area controlled by the visitor location register 15. The mobile station 11 and subscriber information are taken from the home location register 16 and temporarily stored therein, and mounted in the switching station 14.

The home location register 16 is a database for managing various information of mobile subscribers connected to the exchange office 14 and the specialized center 17, and performs functions such as subscriber location registration in connection with various exchange stations 14, It stores the permanent information and location information of the mobile station 11 and subscribers, and interacts with the visitor location register 15 to support various functions related to call processing and additional services.

The single professional service message center 17 is connected to the exchange office 14, the home location register 16, and the single professional service server 18 to play a key role in SMS processing, to set SMS parameters, and It interprets the Teleservice Identifier (TI) and Destination Address and sends it to the corresponding network element. In particular, the single professional service message center 17 transmits a signal input from the switching center 14 to the single professional service server 18 when the message is set to the single professional service server 18.

The single professional service server 18 is interworked with the single professional service message center 17 and connected to an external information provider (IP) through a local area network (LAN) to provide a terminal type of a single professional service subscriber. For example, the service type may be stored, and if it is an On-demand Information Service (IonD) message using the corresponding service identifier, it is transmitted to an external IP.

On-demand information service using the SMS proposed in the present invention is made by a sequential transaction of MT SMS, MO SMS, wherein SMS messages exchanged between the terminal 11 and the network system have a unique TI value according to each role. It has a value, and these values determine what role to play.

2 is a flowchart illustrating a message transmission method in a conventional on-demand information service.

In general, since the service structure of the on-demand information service is constantly changing, it should be managed by the specialized service server 18. Therefore, in the related art, all of the on-demand information services have been provided around the single-specialty service server 18, resulting in a lot of inefficiency. In addition, in order to manage this in the terminal 11, a lot of separate information has to be transmitted, so it is not suitable for the low-speed mono-specialized service.

As shown in FIG. 2, in the conventional on-demand single-service service message transmission method, when a subscriber's selection or request is transmitted to the single-service service message center (SMS MC) 17 via MO SMS (201, 202), However, the menu processing program in the professional service server 18 manages the user's state and transmits the information message corresponding to the current state to the terminal 11 through the MT SMS (203 and 204).

The on-demand information service consists of repetition of this flow by the request of the terminal 11, and manages the progress of the service while leading the user to transmit the desired information according to the current state of the professional service server 18 Is in charge. This is because the configuration of the on-demand information service is constantly changing, and the function of the specialized service is too limited to manage such information in the terminal 11. However, among the messages transmitted in the on-demand information service, the proportion of the same repeated messages is very high.

However, in the related art, since such a duplicate message could not be effectively processed, the message was transmitted every time a request was made, and thus, there was a problem of greatly reducing the efficiency of the network.

In order to solve the above problems, the present invention provides a unique identification number for each SMS message transmitted at the time of an On-demand Information Service (IonD) in a mobile communication system, and maintains a maintenance period for each message. Method of minimizing the transmission message to increase the efficiency of the network by efficiently managing the message through the menu reorganization technique that allows the terminal to automatically identify the service structure and reorganize it when the change is made by using the information of the technique and the transmitted message, and It is an object of the present invention to provide a computer-readable recording medium that records a program for realization.

In order to achieve the above object, the present invention provides a method for transmitting an on-demand information service message in a mobile communication system, in order for a terminal to minimize the number of transmission messages, an on-demand information service required by a user by managing a state of a user menu by itself. A first step of transmitting only a request message to a single professional service server through a mobile originating single professional service (MO SMS); A second step, wherein the single specialty service server assigns a unique identification number to each of the on-demand information service request response messages, records a maintenance period, and transmits it to the terminal through MT SMS; And a third step of the terminal managing the user menu based on a unique identification number of the request response message received from the single-service server. The terminal may further include a fourth step of dynamically reconfiguring the user menu based on the indication identification number of the request response message received from the single-service server.

In addition, the present invention, in order to minimize the number of messages sent by the terminal in the mobile communication system having a processor, by managing the state of the user menu by itself, only the on-demand information service request message required by the user for mobile originating service ( A first function of transmitting to a single professional service server through MO SMS; A second function of the single-specialty service server assigning an identification number to each of the on-demand information service request response messages and recording a maintenance period and transmitting it to the terminal through MT SMS; And a computer-readable recording medium having recorded thereon a program for realizing a third function of managing the user menu based on the unique identification number of the request response message received by the terminal specialized service server. The computer-readable recording medium may further include a program for realizing a fourth function of dynamically reconfiguring the user menu based on the indication identification number of the request response message received from the single-service server. to provide.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a schematic explanatory diagram of a method for minimizing a transmission message for an on-demand information service according to the present invention, in which a terminal 11 transmits only necessary messages to a single expert service server 17 while managing a service progress state. Indicate the process.

As shown in FIG. 3, the method for minimizing a transmission message for an on-demand information service according to the present invention includes only a message necessary for a user while maintaining a state of a user's menu. A request is made (301). That is, when the request for information required by the subscriber from the terminal 11 is transferred to the SMS MC 17 via the MO SMS (301), the MSQ message 17 is requested. The notification message is transmitted to the single-service server 18 (302). In contrast, the single-service server 18 transfers the corresponding information message to the terminal 11 via MT SMS (303, 304).

Method for minimizing the transmission message for the on-demand information service according to the present invention is that the terminal 11 can manage only the service progress state while transmitting only necessary messages, where the terminal 11 maintains the progress state of the service itself. Since only the information required by the user needs to be requested to the single-service server 18, the transmitted message can be greatly reduced. In addition, the use of such a protocol can be adjusted to some extent when a large amount of messages are transmitted, thereby reducing the difference in messages transmitted for each time zone, thereby increasing network efficiency.

Therefore, in this embodiment, the protocol should be able to distinguish each message transmitted from the on-demand information service, and determine the validity of each message. To this end, the present embodiment uses the "Duration Time Stamp Management Method".

The "Duration Time Stamp Management Method" is a method of assigning a unique identification number (ID) to each short service message transmitted and recording and managing a maintenance period for each message. Through this technique, the terminal 11 can store and manage the messages transmitted from the single-service server 18, thereby significantly reducing the number of transmission messages. To this end, items such as "identification number" and "holding period" are inserted into the head data format of the menu message (see FIG. 4B) and the head data format of the information message (see FIG. 5B). A more detailed description thereof will be described later with reference to FIGS. 7 and 8.

Meanwhile, in order for the terminal 11 to proactively provide a service, the terminal 11 should know all the structures of the on-demand information service. For this purpose, the terminal 11 should have a function of transmitting the on-demand information service structure. However, since the transmission of such a structure causes a huge load, in this embodiment, the terminal 11 can automatically reconfigure a service structure that is changed without a separate transmission in order to increase the efficiency of the network. (Menu Reconstruction Method) ".

The "Menu Reconstruction Method" is to effectively receive the structure of the on-demand information service managed by the single professional service server 18 in order to provide a service driven by the terminal. This is to obtain the information from the messages that are transmitted basically, without receiving the structure information separately so that it can be dynamically reconstructed. To this end, "identification number" and "instruction identification number" are inserted into the data format of the short message service message shown in FIGS. 4A to 4D, 5A and 5B, and FIGS. 6A and 6B. You can reconfigure A more detailed description thereof will be described later with reference to FIG. 9.

4a to 4d, 5a and 5b, and 6a and 6b show the data format of the short message service message used in the present invention.

Looking at the data format of each specialty service message is as follows.

4A to 4D, FIG. 4A shows the data format of the menu message, and FIGS. 4B to 4D show the header data format, the menu item data format, and the character string data format of the menu message, respectively.

5A and 5B, FIG. 5A shows a data format of an information message, and FIG. 5B shows a header data format of an information message.

6A and 6B, FIG. 6A illustrates a data format of an input message, and FIG. 6B illustrates a header data format of an input message.

Here, each message has a unique identification number of the message. In addition, it is possible to determine the type of service or the like through this identification number. In addition, the main messages have an "indicator identification number" indicating a message to be transmitted next to them, so that the terminal 11 constructs the service structure by messages transmitted without additional information when the terminal 11 operates the service. I can go. And, each message has a maintenance period, which is specified by the single-service server 18 to ensure that for a certain period of time the message is valid by the single-service server 18. That is, during this period, the expert service server 18 guarantees that the message of the identification number is never changed.

7 is a detailed flowchart illustrating a message transmission process in a short-term service server according to the present invention, and shows a procedure in which the short-term service server 18 transmits a message by using the "maintenance guarantee method".

As shown in FIG. 7, the process of transmitting the message to the terminal 11 by the single-service server 18 according to the "maintenance guarantee method" according to the present invention requires first to transmit a message from the terminal 11. When the message transmission request notification message is received (701), the single professional service server 18 retrieves the message of the requested message identification number and prepares for transmission (702).

Then, the duration of the message is calculated from the expiration time of the message and the current time (that is, the message retention period = expiration time-current time) (703), and after configuring the data of the monoservice message, the monoprofessional message message center (17). In step 706, the terminal 11 transmits the data to the terminal 11 through the C-T. In addition, if you want to prevent messages from being crowded at the time of expiration at the time when the capacity of the professional service message center 17 is insufficient (i.e., if a balancing function is required), the expiration time is widened by giving a deviation to the maintenance period. The data may be distributed (704, 705), and after the data of the short professional service message is configured, the data may be transmitted to the terminal 11 through the short professional service message center 17 (706).

8 is a detailed flowchart illustrating a message receiving process in a terminal according to the present invention, in which a terminal 11 receives a message from a single expert service server 18 according to a "maintenance guarantee method". Indicates.

In this embodiment, the terminal 11 must have a certain size of memory. In other words, this is a ROM that temporarily stores received messages, temporarily storing the received messages in memory, and removing the oldest messages when the storage space is used up. Here, the retrieval of the memory uses the message identification number (ID).

As illustrated in FIG. 8, the process of receiving a message from the terminal specialty service server 18 by the terminal 11 according to the " maintenance guarantee method " according to the present invention is, first, at the request of the user. If it is necessary to request a message from the server 18 (801), the terminal 11 searches the memory using the message identification number (ID) (802) to analyze whether this message already exists in the memory. (803).

As a result of the analysis, if the message does not exist, the message is requested from the single-service server 18 (804) and received from the single-service server 18 (805) to determine whether the retention period of the received message is "0". Check (806).

As a result of the analysis, if the message exists, it is determined whether the retention period is valid (810), and if the message is extracted (811), the extracted message is displayed on the screen (809), and if it is not valid, the message is deleted from the memory. In operation 812, a message is requested from the single professional service server 18 (804) and received from the single professional service server 18 (805), and it is checked whether the retention period of the received message is "0" (806). ).

As a result of the check, if the retention period of the received message is "0", the received message is immediately displayed on the screen (809). Otherwise, the validity period is calculated by adding the current time to the retention period (807) and storing the received message in the memory. After saving (808) it is output to the screen (809).

9 is a detailed flowchart illustrating a menu processing procedure in a terminal according to the present invention, and illustrates a menu processing procedure in a terminal to which a "menu reorganization technique" is applied. That is, the menu reorganization technique is used to dynamically reconfigure the menu while using the "information identification number" of the data format.

As shown in Figure 9, the menu processing process using the "menu reorganization technique" in the terminal 11 according to the present invention, first generates a tree structure in the initial state (901), the current menu identification number Assign to node (902). Here, the current node refers to the node currently selected for menu reconfiguration, and means a message that the user is viewing on the current screen.

On the other hand, the user can select the menu item currently being displayed or move to the previous or subsequent menu through "forward" or "reverse". If a user key (i.e., a forward key or a reverse key) is input from the user ( 903) It is analyzed whether the input key is a "forward" input key (904).

As a result of the analysis, when a "forward" key is input from the user, it is checked whether a menu selected by the user exists (905).

As a result of the check, if the selected menu exists, the message of " instruction identification number " of FIG. 4C is added as a child node of the current node (906), and this child node is designated as the current node (907), and then by the protocol of FIG. Receive a message (908). In this case, it is determined whether the message is received from the single expert service server 18 with respect to the designated identification number (909). If it is not received, the terminal immediately transitions to the user input waiting state (903). After deletion (910), the user waits for input (903).

As a result of the check, if the selected menu does not exist, it is necessary to check whether the current message is a menu message (911) and to advance the menu when the current message is a menu message. After designation as a node (912), a message is received (908) by the protocol of FIG. If the current message is an information message rather than a menu message, this identification number is designated as a child node of the current node only when the "indication identification number" of FIG. 5B is not 0 (913), and the specified child node is currently designated. After appointing with denomination (914), a message is received (908) by the protocol of FIG.

As a result of the analysis, when a "backward" key is input from the user instead of the "forward" key, it is checked whether the parent node exists (915), and if the parent node does not exist, the user immediately transitions to the user input waiting state (903). If a parent node of the current node is designated as the current node since it is necessary to return to the upper menu, the message is received by the protocol of FIG. 8 (908).

The present invention as described above can greatly increase the efficiency of the network and reduce the cost by minimizing the number of messages transmitted in the on-demand specialty service system providing the on-demand information service.

In the present embodiment, the on-demand information service for the user's request is assumed to be a service through the wireless network, but the on-demand information service has the same effect by partially modifying and changing the data format and protocol of the mono-specialized service message presented in this embodiment. It can be configured to be able to produce, and can be configured to produce the same effect in all communication networks, such as a wired network as well as a wireless network, even in this case it should be seen as the same as the embodiment.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

The present invention as described above, by minimizing the number of messages transmitted in the on-demand information service in the mobile communication system can immediately provide the corresponding information for the on-demand information service (IonD) request of the user to satisfy the user's service needs It is possible to increase the efficiency of the network by reducing the load on the network.
