Figure 3 shows in more detail the network environment of the agent server system according to an embodiment of the present invention. The agent server system 40 is connected to a plurality of information provider (CP) servers 60a to 60n, and when requested by the agent manager on the wireless terminal, a new agent is sent from the download server 42 to the wireless terminal in response. To be downloaded to (10). In addition, the server system 40 receives and maintains the agent push data from the CP servers 60a to 60n, and pushes the push data for the corresponding agent based on the state information of each agent on the wireless terminal 10. In one embodiment, download server 42 may be operated by a radiotelephone operator or a third party operator rather than by an agent server system 40 operator. However, in a variant embodiment, the download server 42 may be directly operated by the agent server system 40 operator as part of the agent server system 40.

In the radiotelephone network 20, a radio base station 22 is connected to a plurality of base stations 24 for relaying calls transmitted and received between the radio terminal 10 and the exchange 22. The radiotelephone network 20 includes a plurality of wireless exchanges connected hierarchically, but only one exchange is shown for simplicity. In addition, the WAP gateway 28 is connected to the wireless switch 22 through an interworking function 26. The IWF 26 is a gateway that allows a wireless communication network and a wired communication network to be connected. Since the device is well known to operators in the wireless communication field, detailed description thereof will be omitted. The WAP gateway 28 performs the function of converting the HTTP protocol stack into the WAP protocol stack and conversely converting the WAP protocol stack into the HTTP protocol stack. The WAP gateway 28 is connected to a wireless portal server (not shown) for providing wireless Internet service directly or via the WIG 36 described later.

On the other hand, the short-term service center (SMSC) 30 for providing a short message service is connected to the wireless switch 22, and at least one short-service server (SMSS) 32 is connected to the short service center 30 again. The short message service center 30 is connected to the switch 22 by a common line (SS No. 7) signal system to store and transmit a short message transmitted and received by each terminal user, and the short service server 32 is connected to an external network. Perform the interlock function of.

Agent server system 40 is connected to WAP gateway 28 via a Wireless Interface Gateway (WIG) 36. Agent server system 40 is also connected to SMSS 32 either directly or via WIG 36 or a separate short gateway server (SMS G / W, 34). In this state, the agent server system 40 pushes the push data for the corresponding agent through a short message based on the status information of each agent on the wireless terminal 10 as mentioned above. On the other hand, the agent server system 40 is connected to the download server 42 via a leased line or the Internet, and upon request of the agent manager on the wireless terminal, a new agent is sent from the download server 42 to the wireless terminal in response. Will be downloaded to (10).

4 illustrates in detail the configuration of the wireless terminal 10 and the cyber agent server system 40 according to the preferred embodiment of the present invention. In a preferred embodiment of the present invention, the cyber agent and the cyber agent manager is an application program implemented on the basis of WI-TOP, which is a terminal platform that enables the wireless terminal to download and integrate files into http. That is, as shown in FIG. 4, the wireless terminal 10, from a software perspective, is a terminal OEM module that performs basic voice call processing functions, lower layer data communication functions, text message transmission and reception functions, and terminal management functions. 100 and a WI-TOP platform 120 operating on the terminal OEM module 100, the cyber agent manager 140 according to the present invention of the application program operating on the WI-TOP platform 120 It can be called a kind.

The cyber agent manager 140 notifies the server system 40 of the status of the agent installed in the terminal and serves as an interface for delivering the push data for the agent, which is transmitted in various forms by a short message or a WAP push, to the agent. It performs a function of the control panel that allows the user to control the setting and execution control of the cyber agent (160a ~ 160d). In particular, the cyber agent manager 140 controls a plurality of cyber agents 160a to 160d so as to control the agents so that several agents are simultaneously executable. That is, as will be described later, another agent may execute data that is pushed and then pushed independently of the execution of the agent occupying the idle screen. Meanwhile, in addition to the cyber agent manager 140, other types of WI-TOP applications may be loaded and executed in the wireless terminal 10.

Each cyber agent 160a to 160d is an application program downloaded and installed from the download server 42 under the management of the agent manager 140. The cyber agent 160a to 160d shows push data transmitted from the server system 40 according to the user's setting state. To display as illustrated in FIG. 2N. There are three operation modes of the agents 160a to 160d as follows: " standby screen occupancy " mode, " push wait " mode and " off " mode. Such an operation mode may be set by a user through the agent manager 140. In the table below, the "delete" mode is not an operation mode on the terminal. However, since the "delete" mode may be regarded as a form of terminal state classification for providing a service from the viewpoint of the agent server system 40, this is indicated together. In addition, at least some of the agents 160a to 160d may perform a stand-alone function of performing a specific task.

Operation mode Explanation Standby Screen Occupation Mode -The agent is activated and displayed by occupying the idle screen of the terminal. An operation mode in which an application is driven on the idle screen to receive and execute push data. Push Standby Mode -Operation mode that can receive push data and save or other processing without being activated Off mode -It is not activated so that it is not displayed on the standby screen and cannot receive and process push data, and can perform standalone function. delete -Agent is removed from the terminal and cannot perform standalone functions as well as receive and process push data

The agent server system 40 includes an agent information manager 200, an agent state manager 202, a transfer manager 204, and an external interface unit 206. In addition, server system 40 includes a database 208 having an agent information table 210, a user status table 212, and a transmission queue table 214. In addition, the server system 40 may further include a statistical and operation management unit that provides statistical data for the operator to refer to the operation of the system, and monitors the process so that a quick action can be taken in the event of a failure.

The agent information manager 200 may register information about an agent created by the CP for a new service, and later modify or delete it. The agent registration information registered through the agent information management unit 200 includes the agent ID, name, file size, CP name, homepage URL, etc., as well as the expiration date information of the corresponding agent and the period of use (that is, use is permitted from the date of download). Period of time), the number of times of use (if the number of times of use after downloading is limited), and the like. The CP may check or inquire registration information after agent registration. The inquiry can be made by CP name unit or by a specific agent ID. In addition, the agent information management unit 200 obtains and analyzes the agent download log data from the download server 42 and updates the agent information table 210 and the user status table 212.

When the mode of one of the agents 160a to 160d is changed, the agent manager 140 of the terminal transmits it to the server system 40 in a socket connection method through TCP / IP. The agent status management unit 202 stores / updates user-specific agent status information received from the agent manager 140 in the database 208. The status information includes a terminal identification number, an agent ID, and an agent status (that is, an operation mode). ) And the version of the agent may be additionally included. The terminal state information may also be provided to the CP server that provides the corresponding content by the server system 40. After storing the terminal identification number agent status information, the agent status manager 202 returns the database update processing result to the agent manager 140 of the terminal.

The transmission management unit 204 receives the agent push data from the CP servers 60a to 60 via the external interface unit 206, and checks whether the agent matching the push data is in the data reception mode on the user terminal 10. Thereafter, the data is transmitted to the terminal 10 via the SMSS 32 (or the push proxy G / W as described later).

In detail, the transmission management unit 204 includes a data queuing module, a transmission data verification module, a message generation module, a message transmission module, and a result monitoring module. The data queuing module is a module for queuing the data loaded in the transmission queue table 214. The data queuing module is a daemon type that operates periodically at predetermined time intervals, and extracts unprocessed data from the database 208 to the corresponding terminal 10. It serves to send. The transmission data verification module finally refers to the user state table 212 to determine whether the agent of the terminal to receive the data is in the idle mode or the push standby mode before transmitting the data extracted from the data queuing module to the SMSS 32. Check it. If the agent is not in the standby screen occupancy mode or the push standby mode, the transmission data verification module cannot transmit the data, and thus leaves a log record and deletes the data loaded in the queue.

The message generating module converts the data extracted from the data queuing module into data conforming to the SMSS (or PPG) protocol, and the message transmitting module transmits the processed data from the message generating module to the SMSS (or PPG) and sends the result monitoring module. Is a module that receives the results after the data is processed in the SMSS (or PPG) to generate and record the charging information based on this.

The external interface unit 206 serves as a path connecting the server system 40 and the external CP servers 60a to 60e and performs a role such as CP server connection management and agent status transmission. In detail, the external interface unit 206 includes a connection management module and a connection monitoring module. The CP servers 60a to 60e not only provide content data for push, but also periodically connect to the server to take the current operation mode and additional information of the terminal provided by the user for the agent provided by the user and use it to generate the content. The connection management module manages the connection between the server system 40 and the CP servers 60a to 60e and performs a request from the CP server 60a to 60e to return a result. The access monitoring module monitors the access status of all registered CP servers 60a to 60e, and monitors whether the CP servers 60a to 60e periodically access the server to obtain agent status information. You will be able to cope with the problem.

On the other hand, although not shown in FIG. 4, in the preferred embodiment, the server system 40 further includes a direct transfer manager for mediating agent-to-agent communication and supporting point-to-multipoint group communication. 5 shows a direct transfer manager and database tables necessary for its operation according to a preferred embodiment. Among the database tables, the DT data table 216 temporarily stores data when the data cannot be pushed to the agent, and also stores a file to be sent to the agent by the CP server, and the group information table 218 is a group designated by each agent. Keep information or any other group information defined.

In the direct transfer manager 240 as shown, the direct transfer daemon 242 receives a direct transfer request from an agent via a TCT / UDP socket, and a separate direct transfer thread 244 to process it for each individual request. Create The direct transfer thread 244 transmits the data that can be transmitted in a short message in transmitting the transfer data related to the request to another agent in a short message. However, if the data is large enough to be sent in a short message, the data is stored in the DT data table 218 and notified to the receiver by a short message or by swapping the message so that the receiver's agent requests the data transmission. When the agent is notified that there is data stored in the DT data table 218 and requests the direct transfer request processing daemon 248 to transfer data, the direct transfer request processing daemon 238 will direct a direct transfer request processing thread to handle the data transfer. 248 is generated, and the data stored in the DT data table 218 is read and transmitted to the receiving agent through the direct transfer request processing thread 248.

If the request from the agent is a group transfer request, the direct transfer thread 244 reads the group from the group information table 216 and sends each message to group members. On the other hand, if the target agent is in the off mode as a result of searching the user state table 212, the direct transfer thread 244 notifies the originating agent by a TCP / UDP socket or a short message or a swap push that it cannot deliver the message. do.

FIG. 6 shows the configuration of the cyber agent manager 140 shown in FIG. 4 in more detail. The download processing unit 260 stores the received data when the agents 160a to 160d do not directly receive the data, for example, when the agent is not running, such as when a folder is closed or on a call, and the agent is driven later. It plays a role of delivering the stored data to the agent. The synchronization processor 262 transmits the agent state information to the server system 40 when the user changes the operation mode of the agent. The push processing unit 264 delivers the push data received from the server system 40 to the agent. The SMS processing unit 266 delivers the short message received from the server system 40 to the agent.

FIG. 7 shows the configuration of any one of the cyber agents 160a to 160d shown in FIG. 4 in more detail. The message dispatcher 270 receives a message to be processed by the agent from the server system 40 and delivers the message to the message processing unit 272. The message processor 272 performs a predetermined function for each message type for each message received through the message dispatcher 270. That is, the message processing unit 272 may be referred to as a part for processing an essential function of the agent. The screen processor 274 performs a function of displaying a letter or a picture on a screen in a predetermined GUI manner for the corresponding agent. The sound processor 276 performs a function of generating or playing a sound such as a beep sound, music, or voice. The communication processing unit 278 enables direct communication with the server system 40 by TCP / UDP or MS without passing through the agent manager 140. The setting processor 280 is a part for allowing a user to set the environment of the agent.

8 is a diagram for explaining an operation mode of an agent. In the figure, an arrow indicates a transmission path of push data. The push data received through the terminal OEM module module is delivered to the agent manager through the Wi-TOP platform, and the agent manager delivers each push data to the corresponding agent. Reference symbols a1, a2, a3 and a4 denote respective agents. Here, it is assumed that a1 among four agents is in idle screen occupancy mode, a2 and a3 are in push standby mode, and a4 is in off mode.

If the push data for a1 is received, the a1 agent exposes the push data while occupying the idle screen of the terminal. If the push data for a2 is received, the a1 agent occupying the idle screen of the terminal enters a sleep state and the a2 agent is executed to express the push data. On the other hand, since the a4 agent is in the off state, the agent server system does not transmit the push data for a4 to the terminal.

In case of delivering push data to each agent, the agent manager does not deliver it immediately after receiving it. Instead, it keeps each push data temporarily and delivers push data to the corresponding agent when a specific event (for example, opening a folder) is generated. have. After each push data is exposed once, it can be archived or deleted according to the policy of the agent server system operator or the content provider for the individual agent. Such storage or deletion is determined and executed by the agent manager according to a preset or real-time instruction of the agent server system.

9 shows an agent registration and download process in the cyber agent server system according to the present invention. First, the CP that generates an agent for a new service generates an agent program (step 300), and then registers installation information and an executable file with the download server 42 (step 301). In addition, the CP stores the agent registration information in the agent information manager 200 of the server system 40 (step 302). After that, the user recognizes the service by viewing the advertisement or other notification contents pushed to the terminal 10 or during the wireless Internet surfing process, selects the service, connects to the download server 42 and requests to download the installation information. (Step 304). The download server 42 downloads the installation information by executing the installation information download script according to the request of the terminal 10 (step 306). When the download of the installation information is completed, the terminal 10 requests the execution file download (step 308). Accordingly, the execution file download script is executed and the execution file is downloaded (step 310). When the download is completed in step 312, the connection between the terminal 10 and the download server 42 is terminated (step 314). The agent information management unit 200 receives and stores download log data from the download server 42 periodically or aperiodically (step 316). This information manages billing and information pushing work for the agent of the terminal. It is used to In the terminal, the downloaded agent is executed according to the user's setting (step 318).

10 shows a process in which push data generated by the CP servers 60a to 60e is transmitted to the terminal 10. First, the CP server 60a to 60e connects to the external interface 206 of the server system 40 and then transmits data so that the external interface 206 loads the data into the transmission queue 214. (Step 320). In this state, the transmission management unit 204 periodically extracts data that has not been transmitted from the transmission queue 214 (step 322), and based on the information stored in the user status table 212, the agent of the terminal 10. In operation 324, the controller 12 determines whether the data reception mode is in the data reception mode. Then, the transmission management unit 204 generates the push data in accordance with the SMSS protocol, and transmits it to the SMSS 32 (steps 326 and 328). The SMSS 32 transmits the push data to the terminal 10 and returns the transmission result to the transmission management unit 204 of the server system 40 (steps 330 and 332). The transmission management unit 204 stores the transmission result data in a database for later use for billing and the like, and also informs the CP server of this.

11 shows a process of providing an agent service on a terminal. When the terminal is booted in operation 350, the terminal OEM module (or agent manager) determines whether there is an agent set to the idle screen occupancy mode (operation 352). If there is an agent set to the idle screen occupancy mode, the agent manager continuously monitors whether push data is received (operation 360) while the GUI screen of the agent is displayed on the display (operation 354). On the other hand, if there is no agent set to the idle screen occupancy mode in step 352, the OEM screen, that is, the initial screen set at the time of shipment of the terminal or changed by the user during use, is displayed on the display as the standby screen (356). step). In this state, the agent manager determines whether there is an agent set in the push standby mode (operation 358). If there is no agent set to the push standby mode, the terminal enters the normal call standby mode and the agent service according to the present invention is terminated. However, if there is an agent set in the push standby mode in step 358, the agent manager continuously monitors whether push data is received (step 360). When the push data is received, an agent related to the push data is executed (step 362).

12 illustrates an example of a graphical user interface (GUI) of the agent manager 140. The agent manager 140 manages the agents in a form similar to the 'wizard library' of the current terminal and allows the user to set the mode. As shown in the figure, the agent set to the idle screen occupancy mode and the agent set to the push standby mode are added with different markers or displayed as icons of different types, so that the user is currently set to the idle screen occupancy mode. You can distinguish between agents and agents that are set up in push-standby mode. When the agent operation mode is to be changed, the user moves to the agent icon for which the mode is to be changed by using an arrow on the terminal keypad and presses the 'OK' key. At this time, a screen as shown in FIG. 12 is displayed. On this screen, the user selects the mode change menu (4) by operating the 'up / down' key, selects the desired mode in the combo box, and presses the 'OK' key. Meanwhile, if a specific agent is selected on the upper screen of FIG. 12 and the call key is pressed, the agent is simply executed regardless of the currently set mode.

On the other hand, some of the agents may include a screen editor that allows a service user to directly edit the screen. FIG. 13 shows a screen editing process using a screen editor, and FIG. 14 shows an example of a GUI of the screen editor. First, when the 'menu' key is pressed on the agent display screen shown in the left side of FIG. 14, the agent menu is displayed (steps 380 and 382), and when the user selects the "screen editing" menu (step 384). The detail selection screen shown on the right side of the screen 14 is displayed (step 386). In this screen, the user may select a screen type or set options related to a background screen or a sound (step 388). When the setting is completed, a new screen to which the setting is applied is displayed (step 390).

At least some of the cyber agents according to the present invention may require keypad manipulation in the process of displaying the information and executing other functions. Accordingly, in the case of the agent in the idle screen occupancy mode, it is necessary to distinguish the keypad operation for dialing or other terminal menus for call origination and the keypad operation for agent execution. In one embodiment, when the user opens the terminal folder, the agent in the idle screen occupancy mode is activated and the keypad is occupied by the agent so that all keypad inputs are delivered to the agent. In this case, when the user wants to use the terminal menu, for example, the user can enter the terminal menu by pressing the 'end' key. Meanwhile, in another embodiment, when the user opens the terminal folder, the agent may occupy only the standby screen, and the keypad may be occupied by the terminal menu, that is, the main function performing module of the terminal. In this case, when the user presses the keypad, the terminal menu is executed, for example, a telephone number is directly input, and when the user wants to input data to the agent, the user has to press the 'OK' key, for example.

Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. For example, in the preferred embodiment, WI-TOP has been described as an example of a download platform on which a cyber agent is based, but the present invention is not limited thereto, and is currently commercialized such as GVM, SK-VM, WIPI, BREW, and Java VM. It may be built on the premise of a download platform or other platform that will be commercially available in the future.

In the above description, the server system has been described based on providing the agent data to the terminal agent through a short message or TCP / UDP. However, in another embodiment of the present invention, the advertisement image data may be provided to the terminal by WAP push. have. In such an embodiment, the server system provides the agent data to the Push Proxy Gateway (PPG) by the Push Access Protocol (PAP) to request to push the data to the target terminal. The push proxy gateway may be connected to the IWF through the WAP gateway, and converts the data received from the server system into a form suitable for a wireless network and transmits the data to the terminal using the push over the air (OTA) protocol. For more information about WAP Push and PPG, see "WAP Push Architectural Overview (WAP-250-PushArchOveriew- 20010703-a)" , "Push Message (WAP ), published by the WAP Forum (a trademark of Wireless Application Protocol Forum Ltd.). -251-PushMessage-20010322-a) " , " Push Proxy Gateway Service (WAP-249-PPGService-20010713-a) ", and the like.
