Abstract: The present disclosure relates to methods of tracking user specific tunnels in wireless communication networks, such as a UTRAN/GERAN connected to a LTE network.

Abstract: The present disclosure relates to resource allocation optimisation for dynamic inter-cell interference avoidance in cellular communication networks, such as Cloud Radio Access Networks (C-RANs).

Abstract: This invention provides a method and apparatus for coordinating downlink transmission(s) in a wireless communication system comprising a cluster of base station clients in communication with a base station cluster coordinator. The method comprises: receiving from each of the cluster of base station clients, a UE parameter set for each UE served by the respective base station clients; determining cluster parameter sets in respect of respective transmission modes, based on the UE parameter sets; evaluating the cluster parameter sets at the base station cluster coordinator, in order to select at least one of the transmission modes for the base station clients; generating at the base station cluster coordinator at least one output according to the at least one transmission mode; and transmitting each output to at least one of the base station clients to control the corresponding base station client to perform the selected downlink transmissions.

Abstract: The invention provides a system, method and base station server. According to an embodiment, a system for converting between higher-layer packets and lower-layer packets comprises a downlink base station server and an uplink base station client. The downlink base station server performs conversion of at least one downlink higher-layer packet to at least one downlink lower-layer packet by: receiving the at least one downlink higher-layer packet; converting the at least one downlink higher-layer packet to the at least one downlink lower-layer packet; and transmitting the at least one downlink lower-layer packet to a downlink base station client for transmission over a downlink channel to a downlink user device. The uplink base station client performs conversion of at least one uplink lower-layer packet to at least one uplink higher-layer packet and transmits the at least one uplink higher-layer packet to an uplink base station server.

Abstract: A method of assigning a core to process a packet in a data network and a device using the same are provided in the present invention. The method comprises: extracting a traffic flow identifier from a packet in a traffic flow of a link in the data plane; performing a HASH function calculation on the traffic flow identifier to generate a HASH result V; performing a logical AND calculation on the HASH result V and a preconfigured array size parameter to generate a lookup index; using the lookup index to find a worker index in a preconfigured worker array that represents one of N cores assigned to process the packet; and processing the packet by the assigned one of N cores.
