摘要： A MOAF algorithm is used to resize cells for balancing capacity. The MOAF algorithm bases its decision on a cell and all other cells which the algorithm decides are sufficiently close in a propagation sense to affect the results. The MOAF algorithm also automatically determines those cells in an area which are most heavily loaded and those cells which are lightly loaded. The MOAF algorithm will only decrease the size of a cell if it determines specific adjacent cells that are willing and able to accept the load, and the MOAF algorithm will increase the size of a cell only if there is a nearby heavily loaded cell that requires the removal of load. Moreover, the MOAF algorithm can be tuned (via the threshold parameter T) to shift the focus of the optimization from avoidance of coverage holes to the avoidance of creation of excessive handover legs. Because the changes are electrical rather than physical they can be deployed instantaneously via the network management system thus saving the cost of sending a field crew to the site. Moreover, it is possible to make these changes much more frequently than has been possible in the past thereby permitting the optimization of the network to be done in near real time to meet the temporal changes in the geographic distribution of customers.

摘要： A method of automatic calibration in which the simulation adapts itself to more closely resemble the actual network is provided. For a given network architecture and a probabilistic customer usage profile a simulation provides an estimate of key performance metrics. These simulated metrics are compared against actual measurements from the network. To the extent that they do not match within a prescribed tolerance, an iterative adaptive calibration procedure is used to perturb slightly the probabilistic model of network usage.

摘要： Performance optimization of mobile wireless communication networks is complex and typically requires extensive offline modeling and simulation prior to deploying changes that may have unforeseen adverse effects on the live customer network. It is necessary to calibrate the simulation model against the actual network at a level of fidelity such that the engineer is confident that the simulation's response to network changes accurately reflects the results that would be experienced if those changes were deployed in an actual live network. This process is typically quite time consuming and requires significant case-by-case insight into the workings of the actual network as well as the simulation model. We have invented a method of automatic calibration in which the simulation adapts itself to more closely resemble the actual network. For a given network architecture and a probabilistic customer usage profile a simulation provides an estimate of key performance metrics. These simulated metrics are compared against actual measurements from the network. To the extent that they do not match within a prescribed tolerance, an iterative adaptive calibration procedure is used to perturb slightly the probabilistic model of network usage.

摘要： An approach for performing congestion avoidance in a switching communication system is disclosed. An input port of the switching communication system receives a bandwidth request from a source. The switching communication system includes a bandwidth control processor that examines the bandwidth request, and multiple output ports. The output ports communicate with various destination sites. A congestion avoidance logic within the switching communication system generates multiple clusters based upon a transmission constraint associated with the output ports; each of the clusters corresponds to a portion of the destination sites. The congestion avoidance logic determines a cluster threshold that corresponds to traffic load distribution among the critical clusters. Additionally, the congestion avoidance logic selectively grants the bandwidth request based upon the determined cluster threshold. This congestion avoidance mechanism has applicability to a packet-switched satellite communication system with an on-board switch; the switch has transmission constraints such that the transmitters of the satellite at the output port of the switch cannot simultaneously transmit to downlink cells, which contain station terminals that are within an interfering distance from one another.

摘要： An apparatus and method, for use with the satellite-based communications network, for improving the reliability and speed at which communication between a user terminal and the network is established. The apparatus and method arranges data of a channel request message transmitted from a user terminal to a satellite in the satellite-based network to insure that the most critical data for establishing communication between the user terminal and the satellite-based network is received at the satellite during the appropriate receiving time frame window. The channel request message includes a first data group necessary for establishing a communication link for which information is transmitted between the apparatus and the network, and a second data group including information for decreasing the amount time necessary to establish the communication link. The first data group is positioned at the center of the channel request message, with portions of the second data group at opposite ends of the channel request message. The time at which the user terminal transmits the channel request message is set based on a location of the apparatus within a spot beam, to take into account the appropriate propagation delay time for the message to travel from the apparatus to the satellite in the network, thus assuring that at least the first data group of the channel request message is received at the satellite during an appropriate receiving time frame window.

摘要： In a telecommunications network in which a mobile handset is capable of communicating in both an IP domain and a non-IP domain, the handoff of an existing communications session between the mobile handset and a fixed user is facilitated by a handoff controller implemented in a service control point. The handoff controller implements different handoff methods depending on the status of the fixed user and the transition of the mobile user. Additionally 802.21 Media Independent Handover Function in conjunction with SIP is used to facilitate handover between IP and Non-IP points in the system.
