摘要： In a method for processor overload control in a wireless or other network, a processor occupancy level (“PO”) of a network processing unit is monitored and compared to a target PO. If the measured PO exceeds the target PO, one or more network load sources are controlled to reduce the data load of the processing unit, until the measured PO falls below a designated PO. “Load source” refers to a source of extant and/or potential data traffic through the processing unit, and/or a network control factor relating thereto, the control of which results in a reduction (or prevents an increase) in the data traffic handled by the processor. Examples include existing data flows, new calls, and BE flow window size. The load sources are controlled according to differentiated QOS levels, wherein non delay-critical data flows (e.g., BE flows) are reduced before delay-critical data flows, e.g., EF or AF flows.

摘要： A power sharing process for base station to allocate un-utilized power from a 1x system to an EVDV system is shown. In this process, a power sharing module receives input signals that relate to predicted power allocation for the 1x system and current power allocations for the 1x system and the EVDV system. From these input signals, the power sharing module may determine whether non-utilized power from the 1x system may be allocated to the EVDV system. The power sharing module may provide an indication corresponding to the determination to a scheduler that may allocate the non-utilized power for different forward channels. This technique allows the non-utilized power to be used by the EVDV system to operate the cellular communication system.

摘要： In a method and system for controlling base station processing unit overload and buffer overflow in a unified manner, one or more processing units of the base station are monitored to determine if the processing unit(s) has entered an overload condition. If so, on a per flow basis, the system generates an advertise window for controlling the amount of data in the data flow, as transmitted to the processing unit from an upstream entity. The advertise window is generated taking into consideration both processor overload and buffer overflow factors. By incorporating these factors, the advertise windows collectively serve to limit both processor overload and buffer overflow, on a system wide basis.

摘要： A method and system for selecting traffic processors for processing and transmitting broadcast/multicast service flow in a cellular network includes evaluating processor occupancy of a plurality of traffic processors and selecting the traffic processors with the highest available processor occupancy. The cellular network has one or more base stations that are connected to a radio network controller, the radio network controller having a plurality of traffic processors to process the radio signals and data traffic to be transmitted to the base stations. A required processor occupancy for transmitting the broadcast/multicast service flow to the base stations is estimated and the traffic processors are selected such that their combined available processor occupancy is greater than the required processor occupancy for the broadcast/multicast service flow. The method and system optimizes resource utilization and distribution among the plurality of traffic processors.

摘要： In mesh networks having multiple nodes that communicate data to and from each other, a great number of data transmissions may be initiated and carried out to get data to a proper processing node for execution. To get data where it needs to go (e.g., the proper destination node), a routing algorithm is used to define a set of rules for efficiently passing data from node to node until the destination node is reached. For the purpose of assuring that all data is properly transferred from node to node in a reasonably efficient manner, a routing algorithm may define subsets of nodes into regions and then send data via the regions. Even greater overall efficiency may be realized by recognizing specific adjacency relationships among a group of destination nodes and taking advantage of such adjacencies by rerouting data through regions other than the region in which a destination node resides.

摘要： A method and apparatus are provided for dynamically controlling a high speed wireless communication system to optimize utilization of system resources and increase system throughput. The invention operates to determine an allocation of wireless transmission resources to each user application served by the wireless system in a manner to optimize transmission resources while meeting required QoS criteria for the served user application. After all user applications have been provided a transmission resource allocation in this manner, the total transmission resources so allocated are determined and compared with a ceiling transmission resource level for the wireless system. A portion of the difference between the ceiling and currently allocated transmission resource levels is then made available, according to the invention, to the served user applications in proportion to the initial allocation provided each user application. An admission control methodology is also provided which is implemented in a cooperative relationship with the further resource allocation process of the invention.

摘要： A method and apparatus for adaptively adjusting the power of a probe signal to be transmitted by user equipment based on a characteristic of received signals and system constants so as to increase the likelihood that the probe signal will be detected by system equipment of a communication system. The Doppler shift of a received pilot signal is derived and an adjustment parameter is calculated based on the Doppler shift, time interval between successive probe transmissions, and system constants. The adjustment parameter is applied to the probe signal to be transmitted to compensate for the effects of fading to be experienced by the probe signal to be transmitted.
