Abstract: Disclosed are a method and device for communications, comprising: on a distributed service center, determining function parameter configuration information of the distributed service center, where the function parameter configuration information comprises: a distributed service center device identification, a network identification, a cluster identification, cluster information, a service identification, network service center identification or address information of a core network determining communication needs on the distributed service center on the basis of the function parameter configuration information, and transmitting a communication request message to a corresponding device. When the communication request message transmitted by the distributed service center is received by a network service center device of the core network, the device responds on the basis of the communication request message. When a system broadcast message transmitted via an air interface is received by an end point node, same updates cluster state information on the basis of the system broadcast message. Employment of the present invention not only reduces the load that an access device incurs on the core network in storage and signal processing, but also localizes a control function, thus greatly reducing delay caused by a control plane signaling process.

Abstract: Disclosed are a processing method and device for a radio bearer for transmitting a data stream. The method comprises: determining a quality of service parameter transferred to an access network node by a control entity of a core network; and performing processing on a radio bearer according to the quality of service parameter so as to transmit a data stream needing to be transmitted between the core network and a UE unit. Processing is performed on the radio bearer at the UE unit according to a requirement of the access network node. The radio bearer may transmit the data stream between the core network and the UE unit. The solution herein can solve the problem of mapping multiple data streams having the same service quality to a radio bearer, reduce complexity of a signaling process, ensure quality of service transmission, and support processing of a special packet.

Abstract: Embodiments of the present application relate to the technical field of wireless communications, and particularly to a method and device for data transmission, which are used to solve the problem in the prior art that a retransmission mechanism of an LTE system can meet general requirements for delay and reliability of the LTE but cannot meet higher requirements for delay and reliability caused by the application of new services. The method in the embodiments of the present invention comprises: a receiving side receives data from a sending side through multiple paths, the received data of each path being identical; and the receiving side performs multi-path data combination on the received data. According to the embodiments of the present invention, data is transmitted between a sending side and a receiving side through multiple paths, and data transmitted through each path is identical, so that the purpose of retransmission for many times is achieved, different radio channels can be fully utilized for connection, and the reliability of data transmission can be ensured with low requirements for delay.
