When unused capacity falls below a second preselected threshold, no requests are serviced. When unused capacity is between the first and second thresholds, an existing data connection is dropped if a requested connection is a voice connection and the number of existing data connections exceeds a preselected threshold.Type: GrantFiled: May 2, 2006Date of Patent: October 23, 2007Assignee: AT&T Corp.Inventors: Soohan Ahn, Vaidyanathan Ramaswami

The server provides control messages to various network traffic sources, which can require differing control instructions.Type: GrantFiled: September 30, 2005Date of Patent: September 25, 2007Assignee: AT&T CorporationInventors: Mohan Gawande, Daniel T. Luan, Mark A. Ratcliffe

Patent number: 7200408Abstract: A selective blocking request is sent from a requesting network element to an SCF (system control function component), where the request identifies a targeted network element. The SCF may then block communications from the targeted network element to the requesting network element, or it may send an ACG (automatic code gapping) message to the targeted network element requesting it to stop sending communications to the requesting network element. This technique offers the advantage of allowing an overloaded network element to reduce its workload while informing other components of the network that messages from a targeted network component will not be accepted by the overloaded network element.Type: GrantFiled: December 15, 1999Date of Patent: April 3, 2007Assignee: Lucent Technologies Inc.Inventor: Nick J. Mazzarella

Patent number: 7190766Abstract: A system and method for conducting variable VPA testing is disclosed. The method includes provisions to detect or measure the utilization of a trunk line and use that information to establish a level of VPA testing for that trunk line. Although a wide variety of relationships between the utilization and the amount of VPA testing conducted can be used, the relationship is preferably a generally inverse relationship, in which the amount of VPA testing conducted on a particular trunk is reduced as traffic or utilization of the trunk increases. Conversely, as traffic or utilization of the trunk deceases, the amount of testing conducted on the trunk increases.Type: GrantFiled: September 26, 2002Date of Patent: March 13, 2007Inventors: Randy M. McDonald, Mortimer P. Burnett, Terry R. Droke

Patent number: 7174002Abstract: Performance parameters of a switch may be ascertained by observing its behavior during a brief interval of high call volume. This may be achieved by accumulating call messages on a queue before allowing them to be processed together as a group. Without increasing the rate of incident calls, an accumulation of messages is accomplished by altering the amount of time that elapses between transferring the accumulation to a processing queue. In one implementation, test calls are accumulated in call input queue. Ordinarily, these calls are transferred to a second queue for processing every few milliseconds (the transfer period). By increasing the transfer period, an increased number of calls are stored in the call input queue before being transferred to the second queue. This allows a larger number of calls to be processed by the telephone switch in a given cycle and, hence, allows the switch's operation under increased call volumes to be observed.Type: GrantFiled: November 5, 2003Date of Patent: February 6, 2007Assignee: Nortel Networks, LtdInventor: Peter Burns

Patent number: 7164757Abstract: Methods and apparatus to manage collect phone calling limits are disclosed. A disclosed example method comprises: determining if collect calls from one or more predetermined locations to a terminating phone number have exceeded a collect calls limit; and determining a future date when collect calls will be permitted from the one or more predetermined locations to the terminating phone number if the collect calls limit has been exceeded.Type: GrantFiled: November 9, 2004Date of Patent: January 16, 2007Assignee: SBC Knowledge Ventures, L.P.Inventor: Michael P. Link

Patent number: 7130397Abstract: Apparatus, and an associated method, for detecting and facilitating amelioration of mass call event in a telephonic network. A detector monitors call attempts to form call connections during operation of the telephonic network. When more than a selected level of call attempts are made to a particular one, or more than one, called station within a selected period, a mass call event is considered to have occurred and detection thereof is made. A notifier initiates notification of other network elements in the telephonic network, and the rate at which call connections are permitted with the called stations is limited during the duration of the mass call event.Type: GrantFiled: July 18, 2003Date of Patent: October 31, 2006Assignee: AlcatelInventors: Thomas Lynn Ferguson, Maureen Rose O'Toole

Patent number: 7116767Abstract: An apparatus for controlling telephone communications through a communication switch during intervals of call traffic volume in excess of a threshold call traffic volume includes: (a) a call traffic volume sensing device coupled with the communication switch and measuring the call traffic volume during selected intervals; and (b) a call traffic control device coupled with at least one of the communication switch and the call traffic volume sensing device. The call traffic control device cooperates with the communication switch to involuntarily terminate selected calls through the communication switch when at least one selected parameter is exceeded. The at least one selected parameter includes the call traffic volume.Type: GrantFiled: June 26, 2002Date of Patent: October 3, 2006Assignee: Lucent Technologies Inc.Inventors: ZhongJin Yang, Jie Yao

Patent number: 7068766Abstract: Congestion problems in networks are alleviated with a method that works toward insuring that unused capacity will always exist in elements of a network that are resources which are shared by a plurality of users and which, consequently, can be overloaded. In response to each request to establish a connection over a path in the network, pursuant to a predetermined algorithm the method services the request, declines to service the request, or services the request after dropping an established connection. In one embodiment, when unused capacity on the path is above a first preselected level, all requests are serviced. When unused capacity falls below a second preselected threshold, no requests are serviced. When unused capacity is between the first and second thresholds, an existing data connection is dropped if a requested connection is a voice connection and the number of existing data connections exceeds a preselected threshold.Type: GrantFiled: December 17, 2002Date of Patent: June 27, 2006Assignee: AT&T Corp.Inventors: Soohan Ahn, Vaidyanathan Ramaswami
