Abstract:
The present invention can provide an apparatus and a method for interworking with app information between multiple app store servers. The apparatus enables conventional app store servers to access app information of apps registered in different app store servers through single app store server based on an open service application program interface (API).
Abstract:
An integrated app store apparatus of the present invention comprises an authentication server registering and authenticating a client terminal; a content managing server for any one of registering, searching, and downloading an application; a web application server providing a web front for a user; and an interworking server providing an open application programming interface (API) allowing an external app store to access. Thus, by defining a function of an app store in the form of a standard-based common interface (open API) and supporting various terminals and platform environments, an open app store model available for effectively expanding services no matter whether a type of a user terminal, a service type, or a business environment is changed is provided.

A system for providing a social network service involving a webpage is disclosed. The system for providing a social network service involving a webpage may include a first client which creates a webpage to be provided through a social network service; a social network service server which manages the webpage created by the first client through a database and transmits the webpage in response to a specific request signal; and a second client which transmits the request signal to the social network service server and displays, on a social network service screen, the webpage received in response to the request signal from the social network service server. Therefore, various relationships can be formed beyond a person-to-person based on the webpage.

Abstract:
PURPOSE: A robot client management system for network based robot control and a method thereof are provided to easily connect to an administrator server by various heterogeneous robot clients. CONSTITUTION: A robot server(120) generates a robot object(122) corresponding to a robot client(S30). The robot object extracts information for initializing the robot client, network information related to the robot client, and profile information including the information related to processing of the robot client from the robot client(S40). The robot server transmits the extracted profile information to a URC(Ubiquitous Robotic Companion) server(130) in order that the robot object is registered to the URC server(S60).

본 발명은 커드 시스템을 이용한 분산 처리 환경에서의 검색 방법에 관한 것으로, 임의의 개수 정보를 검색하기 위해 임의의 개수를 위한 2의 승수 개수의 검색 리스트 내에 해당되는 정보를 분산 등록한 후, 분산 등록되어 있는 상태에서, 지정 포인트 어드레스 번호(key_id)와 해당 클라이언트 자체 번호(node_id)를 얻어가면서 해당되는 정보를 순차적으로 검색한다. 기존의 커드 시스템은 네트워크 분할이나 대규모 노드의 동시 가입과 탈퇴에 대한 문제점이 존재했으나, 이를 리플리케이션 리스트를 추가하여 이를 해결하였다. 따라서, 대규모 사용자가 연결된 그리드(Grid) 환경에서 LDAP 프로토콜이 정상적으로 운영이 되기 위한 방법으로 네트워크 분할이나 대규모 노드의 동시 가입과 탈퇴를 효율적으로 대처할 수 있는 효과가 있다.
Abstract:
PURPOSE: An all serializability checking method in an instant update duplication technique using a messaging order of a group communication is provided to reduce an unnecessary message transmission overhead and a withdrawal transaction overhead by performing a global serializability checking before broadcasting an update calculation message. CONSTITUTION: A transmission node transmits an MSN(Message Serial Number) request message to a group communication managing node(S500). The group communication managing node searches an update information table for every dr to check whether a dr has not been processed yet(S502). If there is a dr to be processed, the group communication managing node reads the dr(S504), and searches the dr from the update information table to obtain an MSN(dr) value of the corresponding dr(S506). If MSN(dr)=Φ(S508), the group communication managing node judges that the dr is valid. If MSN(dr) Φ(S508), the group communication managing node checks whether LastMSN(Ni) MSN(dr)(S510). If LastMSN(Ni) MSN, the group communication managing node transmits a withdrawal message to the MSN request node(S518). If every dr has been processed(S502), the group communication managing node allocates a new MSN with a Max MSN value increased by 1 to the node Ni(S512), stores every dw in the update information table(S514), and informs Ni about the newly allocated MSN and the completion of the all serializability checking result.
Abstract:
PURPOSE: A wireless connection device for a multimedia service and a method therefor are provided to construct a TDD(Time Division Duplex) type wireless private network in a limited area using one public communication portable phone and receive a voice telephone call and an Internet service using the wireless private network. CONSTITUTION: A channel management device(210) initializes mobile terminals(110,120,130), transmits and receives subscriber association information with the mobile terminals(110,120,130), and processes the access and paging of the mobile terminals(110,120,130). A wired network interface device(220) connects to an external network and converts a signal transmitted and received to a TDD type mobile terminal. A system control unit(230) connects to the channel management device(210) and the wired network interface device(220), processes a call, manages the registration and state of subscribers, and manages and controls each device.
Abstract:
PURPOSE: A device for estimating a channel in a time division bidirectional communication system is provided to use a channel estimating method from a chip unit, a symbol unit, and a time slot, thereby minimizing an error caused during channel estimation. The device is provided to use a simple averaging method, thereby reducing random FM phenomenon caused by a channel estimating error. CONSTITUTION: A converter(100) receives a transmitted RF signal, and converts the signal into a baseband signal. A matching filter(200) filters the converted signal. A multiplier(300) multiples a signal sampled by a sampling period with chip units from the filtered signal by a midamble sequence for I and Q codes. An adder(400) adds signals as many as all midamble chips from the multiplied signal. An accumulator(500) divides the added signals as many as the number of the midamble chips, and obtains an average value. A channel estimating calculator(600) calculates a channel estimating value through consecutive two time slots or one-time slot from output values of the accumulator(500).

PURPOSE: A rate matching apparatus of a data communication system and a method thereof are provided to match channel-encoded symbols with a transmission rate appropriate for a physical layer to transmit. CONSTITUTION: According to the rate matching apparatus in a digital communication system, a channel encoder unit(220) performs a channel encoding as to input information bits. A multiplexer unit(260) performs a time division multiplexing as to symbols channel-encoded by the above channel encoder unit regularly. A parameter converter unit(1440) provides input parameter value required in the transmission rate matching. And a transmission rate matching unit(1430) reproduces symbols as much as appropriate for a physical layer by puncturing or repetition as to multiplexed channel encoded symbols and then matches them with a transmission rate appropriate for the physical layer to transmit, according to the above input parameter value.
