Provided are a system and method for controlling a workflow across domains on the basis of a hierarchical engine framework. Inventive workflow control makes it possible to configure a flexible hierarchical engine framework and provide a workflow service with low latency. Also, the system and method make it possible to control a workflow by building an engine and a data pipeline across domains.

System and method to control a cross domain workflow based on a hierachical engine framework

Provided is an engine container configured by a workflow engine framework for a cross-domain extension, including a plurality of operators configured to interwork with a plurality of representational state transfer (REST) application programming interfaces (APIs), respectively, a runner configured to sequentially call the plurality of operators according to a request from a client, and a controller configured to control an operation of the plurality of operators and the runner, wherein each operator operates in a pipeline manner to call a corresponding REST API using uniform resource locator (URL) information transferred from the runner and to transfer a processing result obtained by processing data provided through the corresponding called REST API to a next operator.

Workflow engine framework for cross-domain extension

Provided are a data processing apparatus and method for merging and processing deterministic knowledge and non-deterministic knowledge. The data processing apparatus and method may efficiently process various real-time and large-scale data to convert the data into knowledge by merging and processing non-deterministic knowledge and also deterministic knowledge perceived by an expert. Thus, it is possible to adaptively operate in accordance with a dynamically changing application service environment by converting a conversion rule for converting collected data generated from an application service system into semantic data, a context awareness rule for perceiving context information from given information, and a user query for searching for knowledge information into knowledge and gradually augmenting the knowledge information in accordance with an application service environment.

System and method to control a cross domain workflow based on a hierarchical engine framework

A workflow engine framework for creating a single-domain adaptive and a cross-domain adaptive workflow performing platform is disclosed. The workflow engine framework includes: a resource management unit configured to manage resources including engine components and workflow property specification components; a system configuration unit configured to create an engine by assembling the property specification components; and a system control unit configured to drive and execute one or more engines. Further the workflow engine framework is allocated to each of two or more different signal domains and forms a cross-domain adaptive workflow engine framework.

Workflow engine framework

Provided herein is a communication method using MIMO (Multiple-Input Multiple-Output) technology for communicating with a terminal included in each of a plurality of base station cells using a communication apparatus, the method including calculating, by the communication apparatus, the number of terminals included inside a base station cell; generating, by the communication apparatus, pilot signals corresponding to the calculated number of terminals; and allocating, by the communication apparatus, the pilot signals to a terminal that may maximize a network capacity based on the generated pilot signals.

Communication method using multiple input multiple output and communication apparatus performing the same

The embodiments of the present invention are directed to a method and apparatus that synchronize radio nodes using preambles in a radio communication system. An embodiment of the present invention relates to a method of transmitting preambles by a radio node. The method includes generating a first preamble indicating a system bandwidth and a carrier configuration, generating a second preamble indicating a segment identifier used for obtaining a node identifier, allocating the first preamble to a first preamble carrier set, allocating the second preamble to a second preamble carrier set corresponding to the segment identifier, and transmitting the first preamble to a receiving node through the first preamble carrier set and the second preamble to the receiving node through the second preamble carrier set.

Method for transmitting preamble, synchronization method of wireless node and apparatus thereof

Provided is a frame structure designed for distributed access control and OFDMA transmission in a wireless mesh network. Also, a communication method and a network node based on the frame structure are provided. Mesh nodes included in the wireless mesh network may use the frame structure and thus, may have a high prospect of transmitting a network configuration information message and scheduling information for obtaining a resource. Also, a scheduling process of the mesh nodes may be completed within a short period based on the frame structure.
