A system for generating a schedule by generating assignments for the tasks of a project and sequentially scheduling the individual assignments to available resources. First, input information is received which includes a resource calendar and a task list. A resource calendar identifies the resources available to work on a project and any constraints that are associated with the resources. A task list identifies the tasks that must be performed and any constraints that are associated with the tasks. At a minimum, the constraints associated with the tasks must identify each of the resources assigned to the task, and the work-amount that each resource must perform. Next, assignments are generated for each of the tasks. Each of the assignments identifies a specific resource and the work-amount required by the specific resource. Finally, each of the assignments are scheduled in accordance with the provided resource constraints identified in the resource calendar. The resulting schedule maximizes the utilization of the resources by scheduling on an assignment basis. The assignments are individually scheduled into the next available time-slot of the resources, thus, eliminating idle time where a resource is under-utilized.

Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

The invention provides a base-station (BS)-combined direct-through terminal optimized resource allocation method in a direct-through cellular system. In order not to interrupt the normal communication of traditional cellular subscriber links and obtain effective gain brought by device-to-device (D2D) direct-through technology, D2D subscribers are allowed to adopt a resource allocation manner that resources are selected by a D2D subscriber end when uplink and downlink resources of the cellular system are shared; at this time, the D2D subscribers only need to consider the interference to other cellular subscribers (CUs) arising from signals of the D2D subscribers; and meanwhile, a BS centralized-control manner is adopted to carry out resource allocation, the centralized-control advantage of a BS is exerted, a BS and D2D terminal combined optimization manner is fully utilized, and the advantages of the two allocation manners are exerted. The BS-combined direct-through terminal optimized resource allocation method in the direct-through cellular system has the advantages that the resource utilization ratio and availability of a coexistent system which is provided with the D2D direct-through technology are sufficiently improved, the multiplexing gain of the resources are maximally developed, the system capacity is increased, the service types are increased, and the quality of service is ensured; and many chances for resource multiplexing are developed under the condition of limited resources from a novel resource allocation viewing angle.

An operator graph analysis mechanism analyzes an operator graph corresponding to an application for problems as the application runs, and determines potential reallocations from a reallocation policy. The reallocation policy may specify potential reallocations depending on whether one or more operators in the operator graph are compute bound, memory bound, communication bound, or storage bound. The operator graph analysis mechanism includes a resource reallocation mechanism that can dynamically change allocation of resources in the system at runtime to address problems detected in the operator graph. The operator graph analysis mechanism thus allows an application represented by an operator graph to dynamically evolve over time to optimize its performance at runtime.

Embodiments of the invention relate to cellular wireless networks and are particularly suited to networks including different types of base stations. So-called femtocell types of base stations are typically deployed within a subscriber's premises and operate at low transmit power, providing a very limited area of wireless coverage. A femtocell is typically deployed within the area of wireless coverage of a conventional macrocell, occupying the same frequency spectrum and timeslots as the macrocell. A problem can be presented to a user equipment terminal that is close to the femtocell but unable to gain access to it, because the transmissions from the femtocell may appear as interference to the user equipment terminal, preventing it from accessing the macrocell which it could otherwise access. A cellular wireless network according to an embodiment of the invention employs a method of allocating radio resource to femtocells so that the transmissions from femtocells do not occupy the same radio resource blocks as those used by the macrocell for signalling; embodiments of the invention thereby prevent interference associated with signalling to cause a connection to be lost, or prevent a connection being set up.

The present invention relates to a resource allocation method, network controller device and a switching control device allocating resources to a subscriber of a communication network, wherein at least one allowed codec type is selected for the subscriber based on a relative priority information received from the communication network, e.g., from the switching control device (40). The selected at least one allowed codec type is signaled towards a terminal device (10) of the subscriber. Thereby, priority-based user differentiation can be introduced to provide different quality of service based on the allocated relative priority. This allows maintaining high quality services even in high load or low signal strength environments.

A wireless communication network uses backhaul negotiation based upon static and dynamic resource assignment on jamming graphs. Static reuse factor design methods including fractional frequency reuse (FFR) are addressed. The jamming graph is used to summarize the interfering relationship between transmitters (nodes in the jamming graph). Negotiation-based algorithm is used to arrive at a static resource assignment so that a large reuse factor can be achieved while jamming scenario can be avoided. As a result of such algorithm, each transmitter is assigned some resources, over which traffic transmission can be done instantaneously to reduce the packet delay for short packets. Based on the result of static resource negotiation algorithm, a dynamic resource algorithm can be run, such that the resources assigned to different nodes can be share in a bursty traffic scenario to further reduce packet delay for larger packet size cases, while jamming be also avoided.

The resource management method specifically comprises the steps that the current network is divided into a plurality of different wireless network slices according to characteristics of all access services in the current network; a centralized upper layer wireless resource manager allocates a special second-layer wireless resource manager for each slice according to a transmission mode, resource demand conditions and service performance indexes in each slice and performs centralized resource allocation, each second-layer wireless resource manager is responsible for monitoring service operating conditions and resource utilization conditions inside each slice in the running process of the network, and meanwhile, resource adjustment among the slices is performed through distributed interfaces so as to meet dynamic changes of the service performance. According to the invention, a centralized and distributed combined two-layer resource allocation method is adopted, available resources are allocated for the slices in a centralized mode so as to reduce the complexity of resource allocation, and meanwhile, distributed resource coordination among the slices reduces the resource management cost.

An architecture, design, and realization for providing Quality of Service (QoS) to Internet Protocol (IP) networks based on a three-class differentiated service scheme where the service provider uses a resource management system and a schedule optimizer to enable the optimal use of bandwidth and buffer resources at each node or router along the various links between the ingress and egress points in a network. The resource reservation system checks to determine if sufficient bandwidth resources are available along the path requested by the customer for a particular class. The schedule optimizer ensures that sufficient buffer resource allocations and parameter settings are made to optimally reach the predetermined QoS criteria for each of the three classes. The system also contains a mechanism supporting resource reservations providing additional resources along alternative paths if the selected path links fail in the network.
