A two-way cable network offering high-speed broadband communications delivered via virtual private networks over a multi-channel shared media system. Bi-directional transmission of packet to ATM cell based communications is established between a head end communication controller and a number of subscriber terminal units, whereby individual cells are prioritized and routed according to a virtual connection. Virtual connections are organized to support multiple virtual private networks in a shared media CATV system. The virtual private network to which a particular STU belongs is user selectable and has the flexibility of handling multi up / downstream channels with different MAC domains. The present invention can also handle non-ATM MAC domains via the same common ATM switch. To overcome the limited number of addresses inherent to common ATM switches, a mapping / remapping function is implemented in the port cards. Furthermore, downstream as well as upstream traffic are filtered at each STU. In one embodiment, information pertaining to downstream traffic is used to implement predictive scheduling in order to improve the timing associated with the request / grant cycle. In another embodiment, a user has the ability to select a quality of service that best suits the needs of the current application. In a further embodiment, the scheduling function is associated with each of the receivers in order to provide improved scalability.

Various allowable participation types for meeting invitees may be specified, and each invitee's availability is determined accordingly. Location-sensitive travel times (including optional user-specific travel time adjustments) are used in preferred embodiments when in-person participation is required.

Methods, apparatuses and systems directed to synchronizing transmissions among parent and child routing nodes in a hierarchical wireless mesh network. In one implementation, the present invention employs a time slot scheduling algorithm to coordinate communications between wireless nodes of a hierarchical tree. In one implementation, the present invention provides a wireless mesh network where slot scheduling information propagates throughout the mesh, while individual nodes in the mesh compute their respective time slot schedules based on this information and the current state of the network. In one such implementation, a parent routing node computes its slot schedule and transmits certain parameters to its child nodes (as opposed to the schedule itself). The child node(s) then iterates the same scheduling function based on the parameters passed to it to determine the slots with which it should communicate to its parent node and its child nodes

Abstract: The invention relates to a method for scheduling in a mobile communication system where data of priority flows is transmitted by mobile terminals via dedicated uplink channels to a base station. Each mobile terminal transmits at least data of one priority flow via one of the dedicated uplink channels. Moreover, the invention relates to a base station for scheduling priority flows transmitted by mobile terminals via dedicated uplink channels to the base station. Further, a mobile terminal transmitting at least data of one priority flow via a dedicated uplink channel to a base station is provided. In order to optimize base station controlled-scheduling functions in a mobile communication system the invention proposes to provide the scheduling base station with QoS requirements of individual priority flows transmitted via an uplink dedicated channel and to adapt the mobile terminals to indicate the priority flows of which data is to be transmitted to the base stations for scheduling.

The power flexibility of energy loads is maximized using a value function for each load and outputting optimal control parameters. Loads are aggregated into a virtual load by maximizing a global value function. The solution yields a dispatch function providing: a percentage of energy for each individual load, a time-varying power level for each load, and control parameters and values. An economic term represents the value of the power flexibility to different players. A user interface includes for each time interval upper and lower bounds representing respectively the maximum power that may be reduced to the virtual load and the maximum power that may be consumed. A trader modifies an energy level in a time interval relative to the reference curve for the virtual load. Automatically, energy compensation for other intervals and recalculation of upper and lower boundaries occurs. The energy schedule for the virtual load is distributed to the actual loads.

A system, method and computer program product for enhancing a real-time operating system (RTOS) with functionality normally associated with a general purpose operating system (GPOS). A hypervisor that is adapted to perform a real-time scheduling function supports concurrent execution of an RTOS and a GPOS on a system of shared hardware resources.

A functional unit of a processor may be configured to operate on instructions as either a single, wide functional unit or as multiple, independent narrower units. For example, an execution unit may be scheduled to execute an instruction as a single double-wide execution unit or as two independently schedulable single-wide execution units. Functional unit portions may be independently schedulable for execution of instructions operating on a first data type (e.g. SISD instructions). For single-wide instructions, functional unit portions may be scheduled independently. An issue lock mechanism may lock functional unit portions together so that they form a single multi-wide functional unit. For certain multi-wide instructions (e.g. certain SIMD instructions), an instruction operating on a multi-wide or vector data type may be scheduled so that the full multi-wide operation is performed concurrently by functional unit portions locked together as a one wide functional unit.

A handoff control process in a wireless ATM network replaces an old communications connection with a new communication connection. In order to guarantee that no data is lost during the replacement process, an ATM cell level mechanism is used to re-schedule the buffering and transmitting of data streams of the virtual channels (VCs) to be handed-off. In addition, this mechanism is transparent to user applications. The present invention performs three fundamental cell level scheduling functions. The first function is to mark and redirect cell transmission with operation and maintenance (OAM) cells. The second function is to disable and buffer cell transmission until the new path is connected. The third function is to enable cell transmission, starting with the buffered cells across the connected new path.

The iGW is capable of receiving the registration update from the roaming network and updating the iDEN Network with the location of the iDEN Subscriber. If another iDEN Subscriber attempts a dispatch call to the roaming iDEN Subscriber, the iGW facilitates the Dispatch Call. This also works in the reverse direction where a roaming unit with iDEN capabilities was to roam onto a iDEN Network.
