The invention discloses a method for realizing reconfiguration in dual connectivity, a master eNB (MeNB), and a secondary eNB (SeNB). In a process of transferring a user plane bearer of UE to a target SeNB of the same MeNB from a source SeNB, a user plane interface for providing uplink data service and downlink data service is established between the source SeNB and the target SeNB; and in a reconfiguration process, the target SeNB forwards an uplink RLC data PDU to the source SeNB, and the source SeNB distributes a downlink PDCP data PDU to the target SeNB and maintains data transmission with the UE until the reconfiguration is successful. In a process of establishing the connection with the target SeNB by the UE, the user plane interface for providing uplink / downlink data service for the UE is established between the source SeNB and the target SeNB so that the problem that when the UE performs uplink and downlink synchronization with the target SeNB and establishes connection, the UE fails to perform data transmission with a network side at the layer of a micro base station or a low-power node is solved, rapid reduction of the data throughput of the user plane is avoided, and the user experience of the UE during reconfiguration of the user plane is guaranteed.

A method and structure are disclosed for dispatching appropriate data to a network processing system comprising an improved technique for extracting protocol header fields for use by the network processor. This technique includes basic classification of a packet according to the types of protocol headers present in the packet. Based on the results of the classification, specific parameter fields are extracted from corresponding headers. All such parameter fields from one or more protocol headers in the packet are concatenated into a compressed dispatch message. Multiples of such dispatch messages are bundled into a single composite dispatch message. Thus, selected header fields from N packets are passed to the network processor in a single composite dispatch message, increasing the network processor's packet forwarding capacity by a factor of N. Likewise, multiple enqueue messages are bundled into a single composite enqueue message to direct enqueue and frame alterations to be taken on the bundle of N packets.

An access point (AP) transmits a PSMP frame indicating a downlink period provided to each station (STA) and a minimum amount of an uplink period allocated to each STA, and at least one sub PSMP frame indicating an uplink period additionally provided for an STA that transmitted a resource request message for remaining queued data in the uplink period indicated by the PSMP frame.

After transmitting the resource request message, the STA receives the sub PSMP frame after the full period indicated by the sub PSMP frame, and transmits the remaining queued data to the AP in the uplink period indicted by the sub PSMP frame.

The train temporary speed limitation management method comprises the steps that if a train management center TMC receives upgraded temporary speed limitation information sent by an intelligent train monitoring device ITS, according to train information obtained in advance and sent by an object controller OC, the updated temporary speed limitation information is sent to an intelligent train-mounted controller IVOC arranged on a traveling train to enable the IVOC to update temporary speed limitation; and if the TMC does not receive upgraded temporary speed limitation returned by the IVOC within a preset period, the TMC sends temporary speed limitation failure information to the ITS to manage temporary speed limitation. According to the train temporary speed limitation management method based on train-train communication, the information communication traffic between the TMC and the IVOC can be increased, the communication efficiency is improved, and temporary speed limitation management for the rail traffic train is optimized accordingly.

A method ensures that a reduction in data throughput is minimized in the event of a cell change in a GPRS network. When it is determined that cell change is appropriate for a mobile station, the BSS ensures that no further data for the mobile station is transmitted form the SGSN, and then continues to transmit all buffered data to the mobile station. The throughput may be deliberately reduced for a part of this time, so that the system timers become adapted to the reduction in throughput which will occur at the cell change. When the buffer has been emptied, the cell change is effected and, thereafter, that mobile station is prioritised in the BSS, in order to allow any buffered data on the uplink or downlink to be cleared.

A system and method are provided for implementing performance improvements in a multicast protocol for networks that support incipient congestion indications via packet marking in instances of packet loss in the network during time-correlated blockages by providing indications in the physical (PHY) layer. A receiver rate calculation is adjusted so that a loss due to blockage is ignored completely and only packets marked using an Explicit Congestion Notification (ECN) packet marking protocol are treated as losses. Receiver rates are modified based on ECN principles to ignore losses. A NORM receiver rate equation may remain substantially unchanged while a sender is enabled to keep sending at a higher data rate, even in instances of blockage in support of higher system throughputs without defining a completely new receiver rate equation. Time-correlated blockages are not treated as losses.

A selection is then made by the second endpoint of one of the groups of data communication channels included in the first list, by comparing the groups in the first list with groups in a second list. The second list includes groups of data communication channels at the second endpoint on which to send or receive data.
