Abstract: A wireless network access control method is provided. After an RRC connection is established between a first base station and a UE, a radio bearer for the UE is established in accordance with a service request from the UE. When determining that the UE meets a requirement on communication with second base stations whose types are different from the first base station, a dedicated configuration resource is allocated for the UE for enabling the UE to initiate a dedicated uplink detection signal. Dedicated second base stations are instructed to measure the dedicated uplink detection signal initiated by the UE, and one of the dedicated second base stations is allocated for the UE in accordance with measurement results. The UE is instructed to perform data transmission through the second base station allocated for the UE.

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: A data retransmission method and device are provided to resolve a problem of lacking in a retransmission scheme supporting retransmission via different connections in the prior art. In one embodiment of the invention, the method comprises: upon determining that a transmission node corresponding to a terminal satisfies a multi-transmission node retransmission criterion, selecting, by a target protocol layer in a transmitting device and responsible for managing transmission via multiple transmission nodes, and for a retransmission data packet corresponding to the terminal, at least one transmission node; and performing, via the selected transmission node, data packet retransmission. The embodiment is employed to select, upon determining that a transmission node corresponding to a terminal satisfies the multi-transmission node retransmission criterion, and for a retransmission data packet corresponding to the terminal, at least one transmission node, thereby implementing retransmission via different connects, further increasing reliability and throughput of transmission in a system.

Abstract: Disclosed are a data transmission method and a relevant device, which are used for solving the problem that functional partitioning of an integrated node and a transmission node in data transmission cannot ensure a good switching experience, causing relatively low system efficiency. The method comprises: an integrated node recombining an RLC service data unit (SDU) into an RLC protocol data unit (PDU); and the integrated node transmitting the RLC PDU to a transmission node serving a terminal, and the transmission node transmitting the RLC PDU after recombination according to the size of a scheduled transmission block.

Abstract: A dynamic AP grouping method and a dynamic AP grouping device are provided. It is able to provide services to UE in a UE-centered manner as compared with a traditional mode where the services are provided to the UE in a network-centered manner, thereby to prevent the UE from frequently acquiring a network environment, and provide the data transmission service to the UE at a low speed or in a stationary state through APGs. In addition, during the movement of the UE, it is able to transmit the services to the UE through dynamic refresh of APs in the APGs and coordination of the APs in the APG. It is able to reduce the number of handover operations made by the UE, and perform the handover operation in the APG not through a core network, thereby to reduce signaling load of a core network.

Abstract: Disclosed are a communication path determination method and device, which solve the problems of low transmission efficiency and long transmission time delay which may be caused by the existing path which is configured for a small cell needing to access a network for directly communicating through a wireless channel between the small cell and a macro base station. The method comprises: when a wireless node needs to access a network, acquiring, by the wireless node, an optimal communication path from same to the network; and communicating, by the wireless node, with the network through the acquired optimal communication path, wherein the optimal communication path indicates the wireless node to access the network through at least one auxiliary node, and at least one of the at least one auxiliary nodes is a wired node which is directly connected to the network. Since the wireless node accesses the network and communicate with the network through at least one auxiliary node with the function of being capable of providing the data forwarding service for other nodes, the quality and performance of data transmission between the wireless node needing to access the network and the network are improved, and the transmission efficiency of the wireless node is improved.
