Abstract: User equipment (UE)-initiated accesses within a cellular network are optimized to account for cell size and to reduce signaling overhead. A fixed set of preamble parameter configurations for use across a complete range of cell sizes within the cellular network is established and stored within each UE. A UE located in a given cell receives a configuration number transmitted from a nodeB serving the cell, the configuration number being indicative of a size of the cell. The UE selects a preamble parameter configuration from the fixed set of preamble parameter configurations in response to the received configuration number and then transmits a preamble from the UE to the nodeB using the preamble parameter configuration indicated by the configuration number.

Abstract: The present invention prevents performance degradation caused by a multiplication frequency of a memory clock in a wireless communication system by changing a frequency of the memory clock so that a multiplication frequency is not sufficiently close to a transmission/reception frequency that will cause noise or interference with a data transmission/reception. A communication apparatus according to the present invention includes a controller comprising at least one processor; and a memory for operating at a clock provided from the controller. The controller checks a communication frequency, determines whether the communication frequency is a value in a range of interference from a multiplication frequency of a memory clock frequency, and changes the memory clock frequency.

Abstract: A wireless communication access path exists between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations directly or through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add information bearing on an identified QoS associated with the PDU to the PDUs before they are delivered to the downstream egress station(s) or intermediate relay station(s). The information may be used by the downstream stations to schedule the PDUs for further delivery. The information may also be used by the egress station to schedule the PDUs for delivery.

Abstract: A path computation element for a communications network, receives link advertisements from hybrid nodes (10) of the network and selects paths for new traffic flows based on the received link advertisements. The hybrid node has switching matrices (20, 30) operable using different protocols, and has internal links between the switching matrices. The link advertisements indicate a maximum and in a minimum bandwidth on any one of the internal links for a new traffic flow. The element can select a path via the hybrid node for a new traffic flow according to the bandwidth of the requested new traffic flow and according to the maximum and the minimum bandwidth indicated by the link advertisements. Advertising the maximum and minimum bandwidths available for a single new traffic flow for the internal links can enable more efficient path computation with little additional cost and hence maintain scalability of the link advertisements for larger networks.
