Description

Method and system for providing content through content optimized response protocol {Method and System on Contents Delivering Using Contents Optimized Protocol}

The present invention relates to a method and a system for providing content through a content-optimized corresponding protocol, and more particularly, when a user terminal requests content through a first protocol, the requested content using a protocol optimized for the requested content is provided. The present invention relates to a content providing method and a system through a content optimized corresponding protocol provided to a user terminal.

Currently, when a terminal and a server perform communication, it is common to transmit the contents of the server to the terminal through the same protocol as the protocol for requesting the content from the terminal. Accordingly, since content is provided according to a protocol through which request information is transmitted from a terminal while a unique property is ignored for each content, there is a problem in that content providing efficiency is extremely degraded. Accordingly, there is a need to develop a method and a system for providing a content through a content-optimized corresponding protocol in which the content of the content is different for each content and a protocol optimal for delivering the content can be coped with.

Currently, the server system provided in the smartphone uses the web service support system standard rather than the mobile service support system, and provides a service that does not consider the development environment aspect or support service aspect of the mobile service separately. have. Accordingly, the WAS-based smartphone service that provides existing services only supports the Http and https protocols and does not support protocols (HTTP, OBEX, WSP, RPC, RSVP, SyncML) considering the mobile characteristics of smartphones. There was an inadequate problem with the new technology. Accordingly, there has been a strong demand for the invention of a smartphone-only application server that implements a content providing method through a content-optimized corresponding protocol.

The first technical problem to be solved by the present invention is to propose a content providing method through a content-optimized corresponding protocol.

The second technical problem to be solved by the present invention is to propose a system for driving a content providing method through a content-optimized corresponding protocol.

Preferably, the first protocol and the second protocol are different from each other.

The step of selecting the optimal protocol of step (B) is preferably to use the meta information of the content obtained the request information of the content.

The step of selecting the optimal protocol of step (B) is to use the screening priority policy information, wherein the screening priority policy information is determined by any one or more of a content request type, content type, content size and output program. Is preferably.

The user terminal is preferably a smart phone.

In order to achieve the technical problem to be achieved by the present invention, the optimal protocol content providing system receives the content request information using the first protocol from at least one user terminal, the content request information processing unit for providing the content obtained the request information ; A protocol selection engine that selects a second protocol as an optimal protocol for the content; And a content wrapping engine for wrapping the content with the second protocol, wherein the content request information processing unit requests the user terminal to transmit and process the content wrapped with the second protocol. A protocol content providing system is presented.

It is preferable that the protocol selection engine uses content protocol correspondence rule information to select an optimal protocol for the content.

The content protocol correspondence rule information used by the protocol screening engine is meta information of the content, and the protocol screening engine uses the meta information of the content which has received the request information of the content, and the second information as the meta information. Preferably, the protocol is selected.

The content protocol correspondence rule information used by the protocol screening engine is screening priority policy information, and the protocol screening engine is screening the second protocol using a screening priority policy, and the screening priority policy information is content.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a diagram illustrating an exemplary configuration of an optimal protocol content providing system 2000 of the present invention. The optimal protocol content providing system 2000 is connected to the user terminal 1000 through a wired or wireless network 3000. The optimal protocol content providing system 2000 may include a smartphone application server (SPAS 2100, Smart Phone Application Server) therein. The SPAS 2100 includes a protocol layer 2110, a base layer 2130, an application layer 2120, and the like. The SPAS 2100 is a technology that replaces the role of the existing WAS as middleware for a smart phone. The SPAS 2100 is composed of three types of 1) protocol layer 2110, 2) application layer 2120, and 3) base layer. Each layer is similar to WAS, but complements each other in consideration of various communication and service environments of smartphones.

The operating system layer recommends Unix OS in consideration of hardware scalability rather than Window, and important engines for heterogeneous OS conversion are: 1) Implement core engines using Unix C and Window C for system loading and module management. 2) It implements decentralized multi-processing, and it is more appropriate to implement aspect-oriented programming (AOP) for integrated management of processes.

Java J2EE part is based on basic Servlet Architeture for server system implementation. It shares existing standard channel security (SSL), user authentication (X.509 authentication support), and server authentication implementation. With minimal customization, it provides various functions such as efficient application transaction management, session maintenance, and load balancing. In addition, the hierarchical structure makes the business logic relatively easy to implement due to its flexibility and expandability. Low level socket streaming services not supported by J2EE, non-memory sessions not allowed by J2EE, and encryption areas for sessions are areas that require new concept setting and implementation.

As shown in FIG. 3, Java J2EE-based SPAS technology element is divided into 1) server implementation technology into memory management technology, log management technology, exception handling technology, application module standardization technology, and 2) interface implementation. The technology is divided into protocol technology and standard interface technology. 3) Application module implementation technology is divided into detailed component technology into encryption module technology, compression and conversion module technology, moving picture support technology, and distribution module technology. 4) Operation module implementation technology includes server management module technology, performance test / checking technology, It is divided into integrated test / check module technology. In this way, a Java EE-based application server technology for smartphones can be implemented with four key element technologies and 13 detailed element technologies.

The protocol layer 2110 performs a function of providing various specialized protocols required (HTTP, WSP, RPC, RAP, SyncML). The development language is based on Java EE 5, an international standard, which not only provides the administrator screen for developers and system administrators to check efficient applications, but also makes the business logic easier and easier with its layered structure. It is desirable to implement effectively. In addition, it fully supports the optimized service and SOA (Service Oriented Architecture) implementation environment by complying with the Java EE 5 specification, and is designed with user convenience in mind.

The base layer is a layer that is in charge of interworking with database and backbone system. It is a J2EE CA (Connector Architecture) to support integration with CICS, IMS, SAP, Tandom, Ingres, and MQ. It also supports convenient integration with data interworking frameworks such as Jdom and Ibatis. In addition, it supports connection with COM / DCOM through COM Bridge, connection with LDAP through JNDI Bridge, and DB Pool connection with JDBC Driver.

The application layer 2120 is a service function area specialized for a smartphone, and includes a function capable of loading a service in a memory area only through setting of an administrator, not a method of calling from inside the servlet. Application load becomes Proxy by implementing component method of existing stub and proxy concept, and each application service becomes stub, and the function can be loaded and activated only by setting in the management screen. The stability of memory, log and exception handling is secured by J2EE JVM technology, and AOP function is included for integrated management. The most important special function of SPAS is that Application Load guarantees stable operation of various application services.

In the case of distribution function, it provides distributor authentication, distribution device registration, program introduction and payment function.In case of device security, important information of device is remotely checked through Wipe-out by device log request and device user's request. It provides the function to initialize the information. In the case of moving picture service, it performs standardization work and conversion work for service files according to moving picture standards for MPeg4 and 5, and supports compression related codec service. It supports moving pictures related to smartphones equipped with iphone and android operating systems, converts documents for mail attachments and Groupware documents, and converts them into files of internal management type, and stores specific documents through access control. It can support file-related cloud computing.

On the other hand, application loaders make application service modules into stub models, and application loaders provide the functionality of a stub component loader. Considering the portability of stubs to which development standards are applied, it is desirable to implement them as proxy types. It 1) exposes interface to application module and manages service through exposed interface, and 2) manages service state through Load, init, unload, and close commands in application module stub, and 3) develops as development standard. It provides the optimal service environment for the specified stub, and 4) implements the memory management and exception handling, the log function, and the module dependent environment according to the module linkage setting.

On the other hand, for the manager function, it is necessary to be implemented in AOP (Aspect Oriented Programming) method. The manager function needs to be designed and developed to manage the work on cross-cutting concerns at any point in time. The administrator function supports 1) implementation of access statistics and server monitoring function, monitoring and tuning plan for application modules running in the application loader, and 2) user convenience server configuration, context root, DB configuration information and Manage connection pool, 3) Implement process kill and memory free function for hanged process, Implement management function to improve system availability, exception situation availability, 4) Decentralization of server through cluster switching setting ). Implement server redundancy and support continuous service in case of server shutdown.

Next, the spirit of the present invention will be described in more detail.

Table 1 shows an example of an optimal protocol for smartphone content. The optimal protocol shown in Table 1 may correspond to each content type, and the corresponding information may be stored in the content protocol corresponding rule information 2123.

An information processing method of the optimal protocol content providing system 2000 of the present invention is illustrated in FIG. When the optimal protocol content providing system 2000 receives the content request information from the user terminal 1000 transmitted using the first protocol (S11), the second protocol is selected as an optimal protocol for the requested content (S12), After mapping the content to the second protocol (S13), the content is transmitted to the user terminal 1000 using the second protocol (S14).

When the smartphone selects a data communication method and requests a specific content from the server, when a protocol for the specific content is not specified, the smartphone requests only the corresponding data and makes a request through HTTP, which is a basic communication. The optimal protocol content providing system 2000 delivers basic metadata of the content to the application layer 2120 through the base layer 2300 to provide the requested content. The protocol selection engine 2122 of the application layer 2120 maps the protocol optimized for the corresponding content, generates the corresponding protocol, and transmits the generated protocol through the protocol layer 2110. The protocol layer 2110 encrypts the corresponding data by using an encryption module and encrypts the entire data by using a compression algorithm.

The protocol selection engine 2122 of the optimal protocol content providing system 2000 checks meta information of content requested by the smartphone. The content meta information may include a content name, a content type, a content size, a content file extension, a content usage form, a content creation date, a content creator, a content source, and the like. The protocol screening engine 2122 refers to the content type or content size among the meta information, and refers to the content protocol correspondence rule information 2123 to find out what is the optimal protocol for optimally delivering the content of the content type. To select. Examples of the content protocol correspondence rule information 2123 may include information as shown in Table 1 below. In other words, in the case of a video or audio file, the information that the RTSP protocol is an optimal protocol is an example of the corresponding rule information. In this case, the protocol selection engine of the application layer 2120 selects an optimal protocol for transmitting the content requested by the smartphone by referring to the meta information of the content and the content protocol corresponding rule information 2123. Once the optimal protocol is selected, content wrapping engine 2124 wraps the content to be sent to the selected protocol. For example, as the content protocol correspondence rule information 2123, the avi and mov files may be video files, and the RTSP protocol may correspond to the optimal protocol. In this case, if the content requested by the content request information processing unit 2121 is a ***. Avi file, the protocol screening engine 2122 includes optimal protocol correspondence information for the avi type file. With reference to the content protocol correspondence rule information 2123, it can be selected that the RTSP protocol is the optimal protocol for the avi type file. The content wrapping engine 2124 then wraps the ***. Avi file with the RTSP protocol. In this case, the ***. Avi file may be stored in the content DB 2410 of the DB unit 2400 of the present invention. Meanwhile, the inventive concept may be applied to a file other than the content, and such a file is stored in the file unit 2500 of the present invention.

In this case, the protocol screening engine 2122 may utilize screening priority policy information when screening optimal protocols. The selection priority policy information may be one piece of content protocol correspondence rule information 2123. Examples of the priority may include 1) a request form such as a user request, a background service, and data synchronization, 2) a content type, 3) a content size, and 4) an output program. Depending on the type of request, there may be cases where the overall efficiency increases rapidly when the optimal protocol is used, and it is sometimes more efficient to select and apply the optimal protocol according to the content size. On the contrary, when the size of the content is small or the urgency or user convenience such as a background service is not large, there may be many problems even when using the suboptimal protocol or the basic http protocol.

On the other hand, since the content of the user's smart phone may be transmitted in a protocol different from the first protocol for transmitting the request information, it is natural that the smart phone must include an information processing process for such a situation. will be. To this end, even if the request protocol and the reception protocol are different, a specific software development kit (SDK) may need to be supplied to develop a smartphone application (application) that supports smooth communication and content enjoyment. The information processing process needs to support a function of receiving content received in a second protocol rather than a first protocol, and obtaining only the necessary content data portion from the entire data transmitted.

In the description of the present invention, a smartphone has been described as an example of the user terminal 1000. However, the present inventive concept is capable of processing information even when the user terminal 1000 is different from the first protocol and the second protocol. Since any bidirectional terminal will suffice, it will be appreciated that the present invention applies to any such bidirectional terminal. At this time, the SPAS should be interpreted focusing on the function, and the function is not limited to the name. That is, the function performed by the SPAS may be the same even when the user terminal 1000 is a smart TV, a personal computer or a tablet terminal instead of a smartphone. It should be interpreted in response to 1000).

The present invention can be utilized in the overall IT industry, such as information communication industry, smartphone related industry, content industry, communication industry.
