摘要： A method, and apparatus for implementing the method, of resource allocation for a communication session in a network that connects a terminal device and a control device via one or more base stations is discussed herein. The method may include storing identifiers of a set of communication objects associated wide the terminal device. The method may further include acquiring information regarding a first set of resources associated with a first communication session for a first communication object in the set of communication objects. The method may also include allocating a second set of resources associated with a second communication session for a second communication object in the set of communication objects, where the second set of resources comprises a disjoint set of resources from the first set of resources.

摘要： Example implementations described herein are directed to a plurality of control functions connected via a communication network and synchronized, where the control functions communicate packets including control data, the function identifier for the function associated with the control data, and time identifier such as a time identifier representing the synchronized time associated with the control data. Example implementations determine control data associated with the function identifier and the time identifier from one or more packets that has the same function identifier and time identifier, received in the certain time period based on the time specified by the time identifier.

摘要： Example implementations described herein generate plans for the deployment of functions involving the distribution function and the allocation of network resources based on the requirements of the distributed functions on the control system and the network information constituting the control system. Example implementations involve gathering requirements of the distributed functions constituting the distributed control system, information of the network, and information of the plurality of communication devices, and generating a plan for deployment of the distributed functions to corresponding ones of the plurality of communications devices and allocation of network resources to the corresponding ones of the plurality of communication devices based on the gathered requirements and the information of the network.

摘要： In the conventional distributed control system, since each control device updates the data area at a timing when a control packet is received, in a case where there is a difference in communication delay between the control devices or in a case where the communication delay includes jitter, it is difficult to match the contents of data in all the control devices in a case of focusing on a certain moment during system operation. Therefore, depending on the start timing of a control application, the control application operates on the basis of different data between the control devices, thus limiting control performance improvement. Accordingly, time slots on the network are allocated according to the result of a calculation unit, and a cyclic memory synchronization update unit synchronizes the timing of reflecting data in the input/output and the cyclic memory and the timing of using data of a cyclic memory.

摘要： A communication control device of a communication system collects information of a first control device in a second control device via a relay device on a network. Allocation of network resources of the network is controlled based on a procedure of processing the collected information.
