| 20100149986 | METHOD AND APPARATUS FOR PROVIDING QUEUE DELAY INTERNAL OVERLOAD CONTROL - A method and apparatus for handling an overload condition in a communication network are disclosed. For example, the method calculates a call target rate by at least one core signaling network element. The method then uses the call target rate by the at least one core signaling network element to start throttling signaling traffic if a total queueing delay of the at least one core signaling network element exceeds a predefined high threshold in a measurement interval. | 06-17-2010 |
| 20100151837 | METHOD AND SYSTEM FOR FACILITATING PREEMPTIVE BASED RADIO CHANNEL ACCESS CONTROL - Methods and systems for facilitating preemptive based radio access control are provided. The methods and systems include receiving queue data corresponding to a set of requests for highly prioritized communications included on a prioritized queue and utilizing the queue data to determine whether a set of conditions for involuntarily terminating a radio communication session has been met. Session data corresponding to characteristics for each of a plurality of radio communication sessions are also received and utilized to determine which of the plurality of radio communication sessions to terminate if the set of conditions for involuntarily terminating a radio communication session have been met. | 06-17-2010 |
| 20100157816 | Method and System for Evaluating Network Connectivity In Rule-Based Applications - A computer readable storage medium includes a set of instructions executable by a processor. The instructions are operable to assign a unique identifier to each of a plurality of node subsets of a network, the node subsets being created by damage to the network; assign one or more of the identifiers to each of a plurality of components of the damaged network based on a connectivity to the one or more of the node subsets and corresponding identifiers of the node subsets; assign one or more of the identifiers to each of one or more node types of the plurality of components by assigning each of the node types all of the identifiers of any of the components of the node type; and evaluate a first connectivity between a first one of the components and a second one of the components by determining whether they share at least one of the identifiers. | 06-24-2010 |
| 20100165838 | METHOD AND APPARATUS FOR IMPROVING DATA THROUGHPUT IN A NETWORK - A method and apparatus for improving data throughput in a network are disclosed. For example, the method receives at least one packet from a first device, and generates an acknowledgement message for verifying a receipt of the at least one packet, wherein the acknowledgement message comprises a precedence value that indicates that the acknowledgement message is to be handled with a priority in accordance with the precedence value. The method sends the acknowledgement message to the first device. | 07-01-2010 |
| 20110051731 | METHODS AND APPARATUS TO REASSIGN QUALITY OF SERVICE PRIORITIES IN A COMMUNICATION NETWORK - Methods and apparatus to reassign quality of service (QoS) priorities in a communication network are disclosed. An example method disclosed herein comprises performing a temporary QoS priority reassignment for network traffic between a first network element associated with a first user of a communication network and a second network element associated with a second user of the communication network without intervention by a service provider providing the communication network to the first and second users, the first user authorized by the service provider to temporarily reassign a QoS priority associated with the second user, and terminating the temporary QoS priority reassignment based on a monitored termination criteria. | 03-03-2011 |
| 20110063974 | METHOD AND APPARATUS FOR PROVIDING A WINDOW BASED OVERLOAD CONTROL - A method and apparatus for controlling a network load in a packet network are disclosed. For example, the method receives a request from a User Agent Client (UAC), and sends the request to a core proxy server. The method receives a request from a User Agent Client (UAC) and sends the request to a core proxy server. The method increments a counter, if the request is positively acknowledged by the core proxy server. The method decrements a value for a window size parameter by a first predetermined value, and resets the counter, if the request is not positively acknowledged by the core proxy server, and the method decrements a number of outstanding requests if the request is positively acknowledged or negatively acknowledged. | 03-17-2011 |

| 20110158083 | Determining Connectivity in a Failed Network - The disclosed technology, in one embodiment, involves a method that improves the execution speed of graph algorithms that are commonly used by network service providers for network analysis and/or design. The disclosed technology can be use to provide significant efficiency improvements when applied to networks that are separated into several isolated fragments (“fragmented networks”) due to severe damage that may be caused by either natural disaster (such as hurricanes or earthquakes), or planned adversary attacks. In one embodiment of the disclosed technology, a graph algorithm, that is used to determine a characteristic of the network, is not applied directly to the whole network/graph. Instead, the graph algorithm is applied to isolated network/graph fragments that are identified, for example, by using a fragment discovery algorithm. The graph algorithm is then applied to one or more relevant fragments. The results may be combined to obtain a network wide result. | 06-30-2011 |
