Description

Method and apparatus for providing network contents between mobile devices subscribed to different mobile communication services and related devices

The present invention relates to the field of content providing, and more particularly, to a method and apparatus for providing public wireless content.

In general, early domestic and overseas wireless Internet services include a short message system (SMSC) based service and a WAP or ME based micro browser. The WAP or ME-based content uses a wireless Internet network of wireless communication companies, WAP is a protocol used by 011, 017, and 019 services, and 016 and 018 use ME (Mobile Explorer).

However, as shown in FIG. 1, in recent years, a VM (Virtual Machine) based service has emerged to provide multimedia contents smoothly, and thus it is possible to provide multimedia contents rather than simple text-based services to terminals equipped with VMs. . Referring to FIG. 1 illustrating a network content provision according to the related art, the content providing servers 10, 20, and 30 each including a content resource, a content logic, and a communication agent may correspond to a corresponding mobile communication service system 17, 27. Are independently connected to each other, and the plurality of client terminals 15, 19, 25, 29, and 35 each belong to a service of a corresponding mobile communication company and have a unique head number, for example, 011,018.

VM (Virtual Machine), also called a virtual machine, is a system introduced by wireless carriers (SKT, KTF, LGT) to provide various mobile contents than existing text-based wireless application protocol (WAP) contents. GVM, KTF's BREW, and LGT's KVM. Accordingly, the VM-based content develops the content in an environment suitable for each wireless communication provider, and charges the user a predetermined fee for downloading the VM content once. In addition, VM content, unlike the existing text-based WAP content, supports color screens and animations, allowing users to enjoy more vivid contents. VM content has been serviced in four types: First, KVM (Kilobyte Vitrual Machine) is a software technology from Sun Microsystems of the United States designed to fit into small devices such as mobile phones while accommodating the advantages of existing java. It requires 300KB of flash memory and 64KB of main memory, but it can run various games and applications developed in java programming language on mobile phones. With the introduction of KVM, more dynamic contents can be used, and users can enjoy content at a lower cost than WAP because they use the line only when downloading contents, and also continuously download and use other contents compared to the embedded contents. Its utilization is high. KVM is the first in Korea to start commercialization service at LG Telecom. Second, there is a General Virtual Machine (GVM). This is a virtual machine for terminal developed by Shinji Soft Co., Ltd. and developed using Shinji Soft's library. The GVM method is to download and enjoy the contents in binary code using the VM (VirtualMachine) installed on the mobile phone. For example, in Korea, 011 and 017 support GVM and XVM. GVM is a VM based on Ansi-C. Currently, GVM contents are provided with 'fish fishing part1', 'fish frog' and 'magic melody'. Third, MAP (Mobile Application S / W Plug-in) is a plug-in service solution developed by mobiletop independently. After downloading C-based program from server, It is a solution that supports various contents easily using the application interface (API) installed inside. The advantage of plug-in content using MAP solution is that it can use various kinds of contents produced by each C / P (Contents Provider) company compared to the embedded content. I am overcoming to some extent. In addition, content can be operated in any form, such as online or offline, and KTF is currently starting commercialization service. On the other hand, the plug-in service refers to a service that can be used online or offline on the terminal after downloading games and other application software from the server to the terminal using the wireless Internet. The binary runtime environment for wireless (BREW) is Qualcomm's platform for application development for wireless devices for CDMA, with open source code. BREW allows you to create applications that can run on any handset with a CDMA chipset. Because BREW runs between the application and the operating system of the chip, the application can not only code the system interface, but also use the device's features without even having to understand the wireless application. Users can download applications such as text chat, enhanced email, location, games (online or offline), Internet radio, etc. from a service provider's network to terminals with BREW capabilities. BREW is competing to dominate the wireless software market with similar platforms such as Sun Microsystems' Java 2 Micro Edition (J2ME). Early versions of BREW were only for CDMA networks, but later versions can be extended to work on TDMA and GSM networks, etc.

However, since LGT's Kitty Hawk-based VM was launched for the first time in Korea, as described above, there have been many advances in the technology for providing wireless Internet services, but wireless contents still have download services such as ringtones, pictures, and text and wireless terminals. It is hard to deny that they are staying in killing time contents such as games and simple information retrieval services such as e-mail / news / sports / weather. Unlike the wired Internet environment, where multimedia networking is possible at any time with anyone in the world, the wireless Internet has a poor content market environment that can attract subscribers, even considering the limitations of the network infrastructure. Even though many advances have been made, users are limited to using only stand alone content by connecting to a network alone, and do not accommodate the requirements for two-dimensional network contents that support networking between subscriber terminals.

For example, at present it is possible to connect to a network server for an individual to play a game and the server to manage the ranking of the game scores. However, two or more subscribers with different VM platforms cannot access network servers with their terminals and play network games (eg StarCraft, Battlenet, Lineage, etc.). This is because there is no content providing such a service.

That's because different carriers adopt different VMs as their standards, and most content providers (CPs) are poorly financed and can't afford to develop network content that supports communication between all these VMs. In an environment where multiple VM platforms exist, a content provider must develop and supply each content server to provide content to a plurality of mobile communication providers. If a mobile communication provider supports a plurality of VM standards, it has a burden of developing a communication agent and a multi communication environment in charge of each communication. In addition, in order to support communication between different operator terminals, separate content logic must be logically able to operate as one logic. CPs must have a system engineer who understands each language and platform and can develop communication agents.

In order to solve the above problems, the Korea Wireless Internet Standardization Forum was formed and attempted to standardize the VM platform for terminals under the leadership of industry-university research.However, the VM was excluded from standardization and a new middleware standard platform was developed and mounted on the terminal instead. Was determined in such a way. Therefore, the wireless Internet content company has a burden to support another VM platform, and there is a problem that can not provide content to the existing subscriber. In this environment, it is hard to expect to develop contents that can communicate with overseas operators or the wired Internet.

As described above, the following problems exist in the past.

First, there is a problem that the killer content is biased for some killing time or simple information retrieval content.

Second, there is a limitation that only stand alone content can be provided, and the subscriber has a problem of using only content that can be downloaded and enjoyed alone.

Third, there was a problem that each operator adopts various VM platform standards and burdens existing content maintenance when introducing a new VM platform.

Fourth, as the excessive burden on content providers for network content development, it took a lot of time to develop each VM platform function, and there was a burden of securing an engineer for each VM platform function development.

Accordingly, an object of the present invention is to provide a system that can solve the above problems of the prior art.

Another object of the present invention is to provide a method and apparatus for easily providing mass-produced network contents, which can be communicated between terminals of different mobile communication providers at home and abroad, at low cost.

It is still another object of the present invention to provide a method and apparatus for allowing a subscriber to receive high-quality contents by allowing a network to mass-produce killer contents.

It is still another object of the present invention to provide network contents that support communication between different subscriber stations even if a plurality of mobile service provider systems have different types of virtual machines (VMs). It is to provide network contents development, compatibility with existing terminals by integrating wired and wireless Internet service functions, and provide mutual communication functions between different carrier terminals when providing contents.

Another object of the present invention is to minimize the burden of maintenance even if the network solution, not the VM standardization, even if a new VM platform is mounted on the terminal.

Another object of the present invention is to provide a method and apparatus that enables content providers to develop content logic in a short period of time by only developing content logic and to reduce the burden of securing engineers for developing a VM platform function.

In order to achieve the above objects, the system structure according to the present invention, the content providing unit and the plurality of mobile communication service system equipped with the content resource and the content logic are different subscriber terminals even in the state having a different type of VM A content providing server comprising a middleware unit configured to perform a message exchange between the subscriber station and the content logic while in charge of a mutual communication function between the content providing unit and the subscriber station to handle a network communication interface therebetween; It is characterized by having a plurality of subscriber stations.

According to an aspect of the present invention, a content providing unit comprising a content resource and content logic in a content providing server and a middleware unit having a message queue structure for interfacing between a plurality of subscriber stations, and communicating between the subscriber terminal and the content providing unit. The subscriber terminal may call a middleware API requesting a request message transmission in a form supported by the set platform, determine a network address of a server to process the request, and then transmit the request message to the corresponding content providing server. Transmitting to the middleware unit of the; Receiving the request message, the middleware unit interprets the request message and transmits the request message to the content providing server and stores and manages information on call and service statistics in a database management system; In the content providing unit, processing the request according to the set content logic, generating a response, and calling a middleware unit API requesting transmission of the response; In the communication agent in the middleware unit, reconfiguring the response of the content providing server into a message form that can be interpreted by a subscriber station and transmitting the message; And forwarding the response to the subscriber terminal and displaying it on the display again.

The above and other objects, features and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings.

Hereinafter, a preferred embodiment of the present invention for a method and apparatus for providing network content according to the present invention will be described in detail.

First, FIG. 2 is a block diagram illustrating network content provision according to an embodiment of the present invention. Referring to the drawings, a plurality of communication service systems 17, 27, 37, 47, 57 and a plurality of content providing servers 300 are connected through a communication network 400 such as an internet network, and the content providing server. It can be seen that 300 is composed of the content providing unit 200 and the middleware unit 100. The middleware unit 100 performs a mutual communication function and performs a message exchange between the client (15, 19, 25, 29, 35, 45, 55) module and the content logic in the content providing unit 200. The content providing server 300 is configured as shown in FIG. 3 to provide a network content service according to the present invention. The middleware unit 100 generalizes common functions required for content services to facilitate network content development and shorten development time to enable mass production of content. As a result, the content provider may provide network content services to domestic and overseas wireless mobile communication providers by developing only one content logic, content resource unit, and client module. Therefore, it is possible to improve the profit structure by reducing the burden on communication module development and mass-producing network contents.

Referring to FIG. 3, which shows a detailed device block of the content providing server 300 of FIG. 2, the content providing server 300 has a network interface 310 connected to the internet network 400. The network interface 310 is connected to the Internet network 400, the ISP to provide the Internet, the DSU / CSU to perform the demodulation function of the communication data, the router for the network connection, the hub to perform the switch function, the data security function May include a firewall connected to the server bus. And the content providing server 300, the control unit 330 for controlling the overall operation for the service according to the present invention according to a preset program, the input unit 320 connected to the control unit 330 in charge of the input function, A ROM 340 in which a preset program is stored, a RAM 350 as a work memory, a content operating program, and a HDD 360 for storing various related data for each sector. Although the content providing server 300 is connected to the plurality of communication service systems 17, 27, 37, 47, and 57 through the communication network 400 in the drawing, the content providing server 300 may be directly connected to them. 3 preferably has a Pentium III, a main memory of 1GB, a HDD of 20GB or more, in accordance with recent trends, for real-time transmission.

4 is a structural diagram of the software module of FIG. Referring to the drawings, the structure of the software module is largely comprised of a communication agent (hereinafter referred to as CA) unit 130, the middleware core unit 120, the content providing unit 100, and the system resource 110. The communication agent 130 is responsible for the network interface between the subscriber terminal and the content provider. That is, a function of interpreting a service request (REQUEST) transmitted from the terminal, calling an API of the middleware core unit 120 (converted into a message format defined by the middleware), and delivering an application processing result (RESPONSE) received from the middleware. A function of searching for a subscriber station and a function of converting the subscriber station into a message format and delivering a result of the processing. The middleware core unit 120 is responsible for the interface between the communication agent, a plurality of contents logic (hereinafter, referred to as CL) 215 and 225, and a plurality of system resources 110. That is, the service agent 130, the content logic 215, and the system resource 110 perform the routing function of the service request (REQUEST) and processing result (RESPONSE) message. The content providing unit 200 performs a function of processing a service request according to a given content logic to generate a result, and a function of calling an API of the middleware core unit 120 requesting transmission of the processing result. It performs the function of generating the result by processing the service request according to the defined service function and calling the API of the middleware core unit 120 requesting the transmission of the processing result. Include. The content providing unit 220 and the system resource 110 are developed based on the middleware of the present invention. Among the system resources, the DBMS has 10 times the performance of the existing DBMS by using the main memory DBMS, provides the generation, management, and statistical functions of charge related information (usage), and the usage via the middleware core 120. Provides real-time inquiry / prediction and weekly / monthly / yearly statistics through the web.

The program of the software module shown in FIG. 4 is stored in a physical storage medium such as the HDD 360 of FIG. 3 and is loaded into the RAM 350 which is the main memory when the present invention is driven. In FIG. 4, the protocol module 140 and the network modules 150 and 160 show the use of the HTTP protocol and the TCP / IP network module. HTTP (HyperText Transfer Protocol) refers to the protocol used to send and receive HTML files. Since HTTP runs over TCP / IP, there is a TCP port to use, and 80 is specified by default. HTTP works by using Request / Response method. When you request a service, a TCP connection is made, and the server sends a response to terminate the data transfer. That is, after receiving a file transmission, the connection is disconnected and a connection must be made again. In this way, an HTML document can specify any protocol and any host around the world to create a connection for the document request and retrieve the data. Here, the operating system used Linux (LINUX), but can be used in addition to Unix, WIN 95/98, WINDOWS 2000. In addition, development tools can use the GNU C compiler, GNU debugger, and X Windows, and the DBMS can be a database management system that supports ODBC.

5 is a flowchart illustrating a communication agent structure and a service by the module of FIG. 4. Referring to a diagram illustrating a process of processing a request transmitted from a 011 GVM-mounted terminal, a service flow centering on a communication agent CA is shown. The communication agent has a structure as shown in FIG. 5 and transmits a request message of the subscriber station to the middleware core unit 120 and receives a processing result generated from the content logic from the middleware core unit 120 and transmits it to the subscriber station 15. Function. In the drawing, steps (1) through (4) indicate the process of generating a CA process. That is, ① the subscriber station establishes a communication session between the mobile communication terminal and the server through a predefined port number (9410 in this embodiment), and the inetd (xinetd) process, which is a system process residing in memory in the form of daemon, selects Check the port number received through the command. The server's inetd (xinetd) daemon process looks up the / etc / services service configuration information to determine what service is being sent over that port. Again, the inetd daemon process looks in /etc/inetd.conf (an environment file in the /etc/xinetd.d directory) to find out which program (CA) handles that service. ④ The inetd daemon process executes / home / icecreamware / bin / ice_gvm, a communication agent, by using the fork () and exec () commands to create a communication agent (CA) that is in charge of communication with the mobile communication terminal. Through the process of ④, the inetd (xinetd) daemon process directly connects the mobile communication terminal with the newly created ice_gvm process (CA), and waits for a new connection request from another mobile communication terminal. Subsequent communication between the agent and the subscriber station is performed directly without going through the inetd (xinetd) daemon process. (6) The communication agent, that is, the ice_gvm process, interprets the request message of the subscriber station and generates and delivers a message requesting service processing to the content logic through the API of the middleware core. ⑦ The CL that receives the service request generates the result of processing the service (RESPONSE). ⑧ Content logic delivers response (RESPONSE) to communication agent through API provided by middleware core part. 9. The communication agent process reconstructs the processing result into a message in a form previously promised with the subscriber terminal and transmits it to the mobile terminal.

FIG. 6 is a conceptual structural diagram illustrating a message queue employed in the middleware core 120 of FIG. 4. The middleware core has a message queue structure. In the related art, since the control unit 330 of the content providing server as many as the number of subscriber terminals requesting a service must be operated to process a request of each terminal, a large content providing server resource is required to accommodate the request. However, by introducing the core part of the middleware with the message queue function, the content providing server resources can be shared without degrading performance such as terminal waiting time, thereby maximizing the utilization of the content providing server resources and minimizing the content providing server resources. The procedure for communicating between the subscriber station and the content providing server by the above message queue structure is as follows. ① The subscriber station calls the API of the middleware unit requesting the transmission of the request message in the form supported by the platform supported by the terminal, and determines the network address of the content providing server that will process the request. ② The request (REQUEST) ) Send the message to the middleware part of the corresponding content providing server. In this case, encryption may be performed according to the terminal platform. ③ The middleware part receiving the request message interprets the message and then sends the request message to the content provider. Information about the call and service statistics is stored and managed in the DBMS. ④ The content provider processes the request according to the predefined content logic and generates a response. ⑤ The content provider calls the API of the middleware unit requesting the transmission of the response (RESPONSE), and ⑥ the communication agent of the middleware unit reconfigures the response (RESPONSE) into a message form that can be interpreted by the subscriber station and then transmits it. ⑦ It sends a response to the subscriber terminal and the terminal shows it on the display again.

FIG. 7 is a diagram illustrating a structure and a service process of the middleware core unit 120 of FIG. 4. Referring to FIG. 7, the middleware core unit 120 supports the following three communication schemes for providing various types of services. The first is Request and Reply, which is a method of processing a subscriber's request immediately and sending the result back to the subscriber. The second is Subscribe and Publish, which means that the subscriber subscribes to a specific service and publishes the content to the subscriber if there is content satisfying the subscription condition. The third is a general model rather than subscription and delivery, which is a communication method that can collectively transmit a notice (event) or a warning (system check scheduled) to all mobile terminals currently connected. In addition, the content logic (CL) process according to the present embodiment may have one of the following two types. 1) R-type (Resident): Process is created in daemon form at the same time as service / system initialization. It always resides in memory and handles subscriber's requests. It is applied to frequently used CL processes. 2) I-type ( Invoke): A one-time process that is generated on-demand to process a message and terminates when a service request is made by a subscriber. It saves resources by applying to a less frequently used CL process.

Referring back to FIG. 7, the request and reply go through the following steps. ① The communication agent writes a REQUEST message to the RR queue. ② The Router process reads the REQUEST message of the RR queue and determines that the message type is RQ. ③ The Router process writes a REQUEST message to the ORQ to request processing of the CL. At the same time, write to the PRC queue. Invoke process reads REQUEST message of PRC queue and does nothing if it is a request for R-type process. When a request message for I-type process is received, retrieves process info table and creates the process. The CL reads the REQUEST message on the ORQ queue. The CL generates a response (RESPONSE) by the content logic and writes it back to the RR queue. At this point, if the CL is an Invoke process, it terminates. (6) The router process reads the RR queue to determine that the message type is RP. The router process writes a RESPONSE message to the COM queue in order to transmit the processing result to the subscriber station through the CA.

In addition, Subscribe and Publish goes through the following steps. ① The CA receives subscription or cancellation information for a specific service from the subscriber and records it in the SBQ queue. ② The SB process reads the SBQ queue. ③ The SB process submits the information according to the subscription or cancellation request. Write to the table. ④ The CL records the information for providing the service in the PBQ queue. The PB process reads the PRB queue. ⑥ PB process is available under Subscription info. Search the table to search the CA information subscribed (SB). The PB process writes messages to the COM queue only to subscribing CAs.

Notification follows the procedure below. ① CL creates information to be provided using notification type communication method and records it in NTQ queue. The NTFY process reads messages from the NTQ queue. ③ The NTFY process writes service information to the COM queue for transmission to the subscriber station through the CA.

FIG. 8 is a view illustrating queues related to content development of a content provider in the structure of a middleware core of FIG. 4. Referring to the drawings, network content development of a content provider CP is as follows. The content provider can develop complex communication functions necessary for developing network contents through an API that communicates with three message queues in the drawing, ORQ (CP1), PBQ (CP2), and NTQ (CP3). That is, the content provider only needs to develop the message queue and the communication function provided to the method through the API of the method of developing the content logic of the content and providing the optimal communication function among the following figures. The direct communication function with the terminal is then performed by the function provided by the present invention. Since there is no need to develop complicated communication functions, it is possible to produce high-quality contents by shortening the period of development of one content. In addition, the new middleware platform of the handset reduces maintenance costs by eliminating the need to modify existing CLs.

9 is a device block diagram of a wireless communication terminal applied to the present invention. The figure shows a general structure of a mobile communication terminal among subscriber stations. The terminal 1 shown in FIG. 9 controls a call function of a mobile station modem (MSM) 2 for transmitting and receiving data, a display unit 3 for displaying text and multimedia data on a liquid crystal display, and a communication terminal. CPU 4, which is a central processing unit that controls various services for Internet content, RAM 5 as a working memory, and a flash memory 6 that stores a program nonvolatile. 10 is a map diagram of the software module stored in the flash memory 6 of FIG. 9, in which content A1, VM interpreter A2, micro browser A3, operating system A4, and others ( A5) Modules are shown. The network VM content A1, to which the subscriber is to be downloaded via the wireless Internet, is stored in the flash memory 6 together with the VM interpreter A2.

11 to 13 are control flowcharts of execution of a network content service implemented in various types of terminals.

First, the VM content A1 downloaded by the subscriber to the mobile communication terminal is executed in the following order. First, referring to FIG. 11, 1) driving a micro browser (WAP / ME) using a menu button (different for each manufacturer) of a mobile communication terminal (step 511), and ② selecting a desired VM content in a micro browser mode. In operation 512, the browser mode is switched to the VM mode by the mobile communication terminal operating system in operation 513. (3) When the VM interpreter and the VM content are loaded into the memory (step 514), the loaded VM content is executed by the VM interpreter and the VM content is executed on the liquid crystal display 3 as the display unit. ④ VM content is connected to the content providing server by using the IP address and port number recorded in the content when downloading. There are two cases, indirect and direct, as follows. First, indirect connection: To find out the IP address and port number of the desired service, connect to the server (A) having the directory service function and obtain the IP address and port number of the server (B) to which the real user should connect. Access the server (B) by using the send and receive data. On the other hand, direct connection: A direct connection with a server to which a real person connects and exchanges data. The execution of the content is performed by performing step 518 of generating and transmitting a service request message and receiving a service response message and displaying a service processing result. ⑤ When the VM content is terminated according to a specific rule (step 519), the connection with the server is disconnected. ⑥ The operating system switches from the VM mode to the normal mode (mobile phone desktop, eg, time output).

When describing a web-based subscriber terminal, the JVM is automatically loaded in the memory when the user executes the web browser because the web browser has a built-in JVM. The flowchart for the case of using the network content service as the web-based terminal application program is shown as the steps shown in FIG.

Referring to the PDA-based subscriber terminal, the PDA is equipped with a small KVM in place of the JVM, and other environments are almost the same as the general PC environment. Also, because there is no micro browser mode, it does not perform the same mode switching as mobile phones. In other words, when a PDA user launches a web browser, the KVM is automatically loaded into memory. The flowchart of the case where the network content service is to be used as the PDA-based terminal application program includes the steps of FIG.

Referring to the performance by the dedicated terminal, the subscriber can be provided with the service through the terminal dedicated to the network content, not the web based on the PC. In the case of a dedicated terminal, it communicates with a server through a communication library provided with an application program. The service flow chart in this case consists of the steps shown in FIG.

The above advantages according to the present invention can be described as follows.

First, the advantages of the content providing server is as follows. Conventionally, in the development of content, not only a simple content rule, but also various communication and multi-user environments had to be developed, there was a problem that the development was very difficult. According to the present invention, only a simple "content rule" was defined and the complex part was a middleware part. This allows the development to be very easy to develop.

In terms of difficulty of construction, in the past, a content providing server was provided for each mobile carrier to provide a service to each mobile carrier subscribing terminal. However, if only one content providing unit was developed, the remaining complex and difficult parts were assumed to be in charge of all mobile carriers. There is an advantage to be able to provide services to the subscription terminal.

In terms of communication difficulty, the content providing server that implements the network function of each mobile carrier is not easy in the related art, but the network function between different content providing servers is very difficult, and the development and maintenance are very difficult. The middleware department provides not only communication between mobile phones but also mobile phones of other mobile carriers, which makes it easy to maintain and network between users of wired / wireless networks and mobile phones, PDAs, and PC users. .

In terms of similar content development, when this VM content is called "Everland", when developing new network content "Disneyland", it takes the same difficulty and solves the problem of difficult development for a long time, and the middleware department "content logic" It plays the role of a network content manufacturing plant that provides all parts except ", which has the advantage of mass production of a large amount of content in a short time.

As described above, according to the present invention, there is an effect of providing a new electricity to the domestic wireless Internet environment that has been developed in the center of technology to the center of content. That is, the content provider can easily and quickly develop network contents capable of communicating between different mobile carriers and different VMs in Korea as well as in Korea and abroad through the present invention. In addition, by mass-producing a large amount of content quickly, it is possible to preoccupy and lead the market, and implement only content logic irrespective of the system / network complexity, thereby facilitating content maintenance by adopting a new VM standard. In addition, IDC and ASP operators have the advantage of reducing initial investment through server hosting.

The present invention described above is described with reference to the drawings, for example, but various changes and modifications are possible to those of ordinary skill in the art within the scope not departing from the technical spirit of the present invention according to the matter. . For example, the detailed structure and operation of the middleware server may vary from case to case.
