A method for scheduling packet data transmissions in a wireless communication system is described wherein a priority function is based on a channel state indicator (CSI), the projected average throughput of the users, and a tuning parameter designed to control the throughput and fairness characteristics of the scheduling algorithm. The method also considers fairness criteria dictated by predetermined Quality of Service (QoS) requirements. The channel state indicator may be a Requested Data Rate (RDR) or Carrier-to-Interference ratio (C/I) information. The base station calculates a priority function for the multiple mobile users. Each priority function is a function of the CSI, the projected average throughput of a given mobile user, the average projected throughput over a set of users, and the tuning parameter.

The present invention relates to systems, apparatus, and methods of enhancing prefecher functionality by scanning responses object requests. In certain embodiments, prefetching is improved by identifying references to container objects or sections of container objects at a proxy server. When URLs are identified as part of a container object, a prefetching determination or adjustment to a prefetching decision is made according to the identification of the reference for a subset of URLs identified by the reference to the container object. For example, prefetching of URLs located in cascading style sheet (CSS) files may be restricted to a subset of URLs which are identified by a CSS rule.

A development and runtime framework for applications that execute in real-time operating systems. Application development is enhanced through simple instructions that allow a programmer to declare functions and sets of functions as tasks and supertasks, respectively, and manage the execution of functions, tasks and supertasks with priorities. A compiler or pre-processor provides tools for generating the code for tasks and supertasks, and the management code for managing execution. Function calls may be made directly to functions within supertasks via respective entrypoints, and the tasks are managed based on the functions being invoked. Within a supertask, a higher priority function may be runnable while a lower priority function of that supertask is suspended. A cookie is used to recognize when a register update for a supertask may be omitted, enabling more efficient context switching.

A priority function is used to select entities and/or relations from the candidate entities and/or relations. The selected entities and/or relations are then added to the seed graph to generate the customized knowledge graph.

A method (18) for scheduling packet data transmissions in a wireless communication system wherein a per-user Priority Function (PF) (24) is based on a channel condition indicated by a Rate Request Indicator (RRI). The method also considers fairness criteria dictated by predetermined Quality of Service (QOS) requirements. In one embodiment, the rate request indicator is a Data Rate Request (DRR). In another embodiment, the rate request indicator is Carrier-to-Interference (C/I) information. In the exemplary embodiment, the base station calculates a Priority Function (PF) for the multiple mobile users. Each PF is a function of the rate request indicator and the projected throughput of a given mobile user. The PF values allow the base station to schedule active mobile units having pending data. The scheduling produces an approximately equal share of the allocated transmission time to the multiple mobile stations.

A method and circuit for a high speed interface that enables the integration of several Content Addressable memories into a larger, Combined Content Addressable Memory with only an insignificant delay in the original response time of the individual memories. The interface provides connections to the Bus system only and no connection between different CAM devices of the system is needed, whereby the combination of one CAM and one CAM interface in a single device, such as a chip is enabled. Such chips may be used as modules for increasing the CAM Memory by directly attaching them to the Bus System without any additional interface, as known for standard memory chips such as RAM. The inventive interface may also be used for creating a hierarchical structure within a CAM device by dividing the memory cells in groups, each group being interfaced to the larger combined CAM device via an interface according to the invention. In such a structure the priority function in each group operates on a smaller number of cells and due to the relatively small number of gates necessary for making the interface the implementation of a CAM device with a reduced number of gates is facilitated. In a combined CAM device several CAMs are connected to an Address Bus and to a Data Bus via their respective interfaces. In the Read and Write mode, the interface will connect the two sets of lines and thus be transparent for the Read or Write operation. In the search mode (Content Addressing mode), the Interface will select and set a number of lines of the Data Bus according to the CAM response so as to output the address of one matching cell that is the highest in a predefined direction. The interface circuit adds the logic functions and lines necessary to expand the Content addressable functions of the CAM module to a larger range of addresses, sets an additional number of bus lines in order to write the address of the cell within that larger range and checks that no other cell with a higher address responds throughout the system by masking the bits of the CAM address if they would change the address of a cell with a higher address. In this way the whole ensemble of CAMs is capable of functioning as a single CAM of larger size.

The invention relates to a cache scheduling strategy based on message priority. Aiming at the problems of limited cache resources, redundancy of message copies and the like in an existing opportunitynetwork, the forwarding and deletion of messages are optimized by consideration of the management of opportunity network caches. A priority function is established according to the transmission success ability, service ability and residual tolerance delay time of a message carried by a node, and a data packet forwarding and discarding strategy is carried out according to a priority value queue. When a connection is established between nodes, a message sending node preferentially forwards messages with higher priority values; and when a message receiving node buffer is full and unable to acceptany new arriving data packet, messages with lower priority values are deleted firstly. Moreover, a threshold is set according to the average transmission success rate of all nodes. Messages with priority values being less than the threshold are put in a to-be-deleted region in a queue, so that the transmission of inefficient message copies is reduced, and the waste of network resources is avoided. Through adoption of the cache scheduling strategy, the problem of message congestion in the network can be relieved effectively, and the data transmission efficiency of the network is increased simultaneously.
