Abstract: A communication network includes an overload control algorithm that adapts to changing circumstances. In a disclosed example, an acceptance fraction for each of a plurality of message types depends upon the arrival rates of the message types. As at least one of the arrival rates changes, the acceptance fraction is responsively changed to provide an overload control algorithm that adapts to changes in message traffic.

Abstract: At least one example embodiment discloses a method of generating a radio frequency (RF) map of a network. The method includes obtaining, by a controller, received signal strengths of at least one user equipment (UE) in a first technology network, determining, by the controller, a back projection of a second technology network based on the received signal strengths, and generating, by the controller, an RF map of the second technology network based on the determining. The back projection represents an attenuation function of a coverage area of the second technology network and the RF map illustrates the attenuation function of the coverage area of second technology network.

Abstract: The present invention provides a method that includes receiving, at a server, one or more alarms from a first cell in a plurality of cells. The alarm(s) indicate that the first cell has detected a candidate sleeping cell in the plurality of cells based on an activity and/or a load on a communication link between the first cell and the candidate sleeping cell. The method also includes determining, at the server, whether the candidate sleeping cell is a sleeping cell using the alarm.

Abstract: Embodiments of the claimed subject matter provide a manifold network for a wireless communication system. One embodiment of the wireless communication system includes a plurality of base stations and one or more radio network controllers communicatively coupled to the base stations. The base stations can be configured to provide wireless connectivity within a geographic area such that user equipment in the geographic area maintain a substantially continuous call connection with at least two of the plurality of base stations. The radio network controller can be configured to select an active set of base stations from the plurality of base stations for the user equipment. The radio network controller can also be configured to select a configurable number of the plurality of base stations from the active set to maintain the substantially continuous call connection with the user equipment. The configurable number is at least two.

Abstract: The present invention provides a method of determining handoff parameters. One embodiment of the method includes determining values of a hysteresis for a handoff from a serving cell, one or more pairwise offset values for hand off between the serving cell and one or more neighbor cells, and one or more times-to-trigger (TTTs) for hand off between the serving cell and the neighbor cell(s). The values may be determined So that hand off is triggered beyond a first distance from the serving cell selected to avoid ping-ponging and within a second distance from the serving cell selected so that a mobile unit moving at a selected velocity does not travel beyond a third distance within the TTT.

Abstract: The present invention provides a method of assigning cell identifiers to a plurality of cells. The method includes detecting cells within a selected distance from a first cell in the plurality of cells. The distance is selected to encompass portions of neighbor cells of the first cell and neighbor-of-neighbor cells of the first cell. The method also includes assigning a first cell identifier to the first cell. The first cell identifier is different than cell identifiers assigned to the cells detected within the selected distance from the first cell.

Abstract: A bandwidth packing rate control technique includes altering bandwidth allocations of existing flows on a link depending on a current utilization of a current bandwidth allocation for a flow. A disclosed example decreases the bandwidth allocation for flows that are utilizing a current bandwidth allocation below a selected target utilization rate. Flows with higher utilization can receive increased bandwidth allocation, which provides increased throughput for such flows. One overall result of a disclosed example is increased utilization and increased throughput using existing bandwidth resources.

Abstract: By approximating a packet network, such as the Internet, by an M/M/1 queuing model, the available bandwidth of the network can determined from the variance of the distribution of the sojourn times of packets transmitted through the network. In order to determine the variance of the distribution of sojourn times, and thus the bandwidth of the packet network that is available for transport of packets from an input to an output, a probe train of N packets with known inter-packet intervals is injected from an input on a sending side of the network. At the receiving side of the network, the packet arrival times are measured and the inter-packet intervals of each pair of received packets in the received train are calculated and compared with the known inter-packet interval times of the corresponding input packets.

Abstract: A method for determining an optimal configuration and redundancy allocation for a system containing a plurality of units grouped into a plurality of elements and one or more modules. The method conducts random statistical sampling of a combinatorial space reflecting the possible combinations, redundancies and integrations of the units and elements in a given system. For each sample combination, the method calculates an optimization metric that reflects the reliability and/or the cost of that combination. The optimization metric may incorporate relative weighting of constraints used to evaluate whether the combination is optimal. The optimum configuration will be the configuration having the lowest optimization metric out of all the samples.
