Abstract:
Provided is a wireless communication method. At least an interfering link is selected from a plurality of wireless communication links. At least a first wireless communication helping device group of the at least interfering link is determined, wherein the at least first wireless communication helping device group includes at least a wireless communication helping device. Based on respective interfering improvements of the at least first wireless communication helping device group on the at least interfering link, at least a target interfering link is selected among the at least interfering link. The at least target interfering link is re-established.
Abstract:
Disclosed are a method and a system of device-to-device tunnel establishment between small cells, applied to a wireless backhaul management device, a first small cell and a second small cell. The method comprises: matching the first small cell and the second small cell according to a first discovery response and a second discovery response; submitting a match report; replying with a match report response; conducting a D2D connection authentication procedure between the second small cell and the first small cell; wirelessly connecting the second small cell and the first small cell, conducting a connection test and submitting a connection test report; replying with a D2D tunnel establishment decision according to the connection test report; and establishing a D2D tunnel between the second small cell and the first small cell.
Abstract:
A method for interference coordination, a network server, and a communication system are provided. The method includes the following steps. A first macrocell almost blank subframe (ABS) pattern is received from a first macrocell. A second macrocell ABS pattern is received from a second macrocell. A first small cell ABS pattern for a first small cell is determined according to the first macrocell ABS pattern and the second macrocell ABS pattern. The first small cell ABS pattern is transmitted to the first small cell. The first small cell is within a coverage of the first macrocell.
Abstract:
A cell and a method and a system for bandwidth management of a backhaul network of the cell, adapted for arranging a routing path of a bearer established between a user equipment and a serving gateway through the cell in the backhaul network, are provided. In the method, the cell connects the user equipment to establish the bearer between the user equipment and the serving gateway or change an established bearer. The cell sets a packet label on the data packets of the bearer and transmits the packet label and bandwidth management information of the bearer to a controller of the backhaul network for the controller to arrange the routing path of the data packets using the packet label in the backhaul network according to the bandwidth management information.
Abstract:
A software defined network (SDN) and a corresponding mobility management method and a corresponding controller are provided. The SDN includes a controller, a plurality of switches and a plurality of edge devices. The controller manages a topology and routing actions of the SDN. When a user equipment (UE) attaches to a target edge device in the edge devices, the target edge device transmits a notification message to the controller. The controller updates flow entries in the switches and the edge devices according to the notification message.

Abstract:
A home base station and method for supporting a plurality of cells under carrier aggregation. The home base station includes a preamble generator and a preamble monitor. The preamble generator allocates respective random access resources in the cells for handover to be carried out by a user equipment (UE), and upon receiving a handover request signal transmitted by a Mobility Management Entity (MME), generates a specific preamble and its transmission time, so that the UE performs random access on the cells based on the preamble and the transmission time to obtain the random access resources and sends out a Random Access Preamble (RAP). The preamble monitor enables the cells to simultaneously monitor the RAP sent by the UE, and when one of the cells receiving the RAP, identifies the cell on which the UE camps based on which one of the cells that has the RAP.
