  • Patent number: 6510218
    Abstract: A method for directional distribution of allocation in two-way alternate line bundles which are switched between computer-assisted exchange facilities in voice and data networks. This traffic management method makes it possible to ensure full capability of a two-way alternate line bundle, while on the other hand, when traffic in one direction is temporarily dominant, traffic flow in the other direction is not impaired or displaced. A ratio for dividing the traffic in the outgoing and incoming directions is entered into the exchange facilities for the two-way alternate line bundle connecting them. The division ratio depends on the normal traffic flow in the outgoing and incoming directions. The allocation and direction of allocation of each line of the line bundle are constantly monitored by each of the two exchange facilities. As long as more than one line of the bundle is free, both exchange facilities can access the lines as required by the incoming connections.

  • Patent number: 6252950
    Abstract: A traffic control system (and associated method) according to the present invention includes a feedback control mechanism in which the controlled variable is processor occupancy, the controlling variable is the amount of resources necessary to satisfy the operational requirements of the switching system, and the set point is the average expected load based on a Poisson arrival rate. Current processor occupancy is compared, on an instantaneous basis against the set point to determine if it exceeds the average expected load. If so, the controlling variable is adjusted to allocate additional resources to process the offered traffic load. The process continues until the traffic burst expires. Additional resources may be obtained by eliminating or deferring non-essential work, and by allocating additional call registers, effectively accepting work in larger increments or batches.

  • Patent number: 5978358
    Abstract: The switch capacity prediction process of the present invention collects operational measurements from the cellular switch. These operational measurements indicate the frequency of the call events processed by the switch. The other input/output (I/O) time used by the call processor to process messages not related to call processing is separated from the call processing I/O time. A relationship between the other I/O time and the sum of the call processing time and call processing I/O time is determined. A weighted average is determined from the summation of the products of: the frequency of events and the call processing time, the frequency of events and the call processing I/O time, and the other I/O time. The weighted average is then divided into the call processor occupancy time, in hours, to determine the switch capacity.

  • Patent number: 5974126
    Abstract: It is proposed that in a telecommunications network (KN) for control of mass callings to subscribers of the telecommunications network (KN) with exchanges (VST1, . . . , VST7), each of which has a control means (SM1), to perform measurements to detect a mass calling to a subscriber exclusively in those exchanges (VST1, . . . , VST5) of the telecommunications network (KN) to which a subscriber, who is the possible target of such a mass calling, is connected. The exchange (VST1) which detects the mass calling signals its occurrence to respective predetermined further exchanges (VST2, . . . , VST5, VST7) in the telecommunications network (KN). Each of the predetermined further exchanges (VST2, . . . , VST5, VST7) and the exchange (VST1) which detects the mass calling, chokes the traffic to this subscriber at a rate that is fixed for the respective predetermined further exchange.

  • Patent number: 5956393
    Abstract: The present invention relates to a system and a method for limiting call velocity attempts in the public switched telephone network. A central office of the network is provided with a program element that examines all the physical channels from respective customer premises equipments (CPE). The program element counts the number of times each CPE goes off-hook within a given period of time. This condition is interpreted as an attempt to establish a call through the telephone network. If the number of attempts exceeds a threshold, the physical channel is de-activated for a predetermined time period. De-activation means that call establishment over that channel is negated for all possible destinations. This can be implemented by preventing establishment of dial tone. In a variant, selective de-activation is effected.

  • Patent number: 5933481
    Abstract: A method of controlling call traffic in a telecommunication system by dynamically altering the rate at which offered calls are accepted includes the steps of successively determining the offered call rate, and accepting calls from the offered calls, at a lower rate, as the offered call rate increases. For accepting the offered calls, at least two call-gapping intervals are used. The method includes selecting the shorter gapping interval whenever the offered call rate is below a threshold value and the longer gapping interval whenever it is above that value.

  • Patent number: 5923742
    Abstract: A system and method for detecting mass addressing events comprising a first register, a second register, a first counter, and a second counter is disclosed. Potential mass addressing events are detected by comparing a most recently selected address to the contents of the first register and incrementing the first counter if they are equal, or loading the most recently selected address into the first register and initializing the first counter if they are unequal. If the first counter's count reaches a first count threshold, the contents of the first register are compared to the contents of the second register and the second counter is incremented if they are equal, or, if they are unequal, the contents of the first register are loaded into the second register and the second counter is initialized. If the second counter's count reaches a second count threshold, an alarm is issued.

  • Patent number: 5903635
    Abstract: An advertising effectiveness rating system provides advertising effectiveness rating data by assigning one telephone number to each of a plurality of advertising outlets and counting the number of times that each of the assigned telephone numbers are used. The advertising effectiveness rating system includes an advertising effectiveness rating device that receives a called number from a local switch. When a prospective purchaser calls one of the assigned telephone numbers, the local switch forwards the called number to the advertising effectiveness rating device. When a called number is received, the advertising effectiveness rating device retrieves a count that corresponds to the called number from a database, increments the count and returns the incremented count to the database.

  • Patent number: 5881140
    Abstract: A telecommunications network (10) includes a plurality of telecommunication switches (12). Each telecommunication switch (12) includes a set of processors (14) in order to provide a distributed architecture. A network processor (16) periodically communicates with each set of processors (14) of each telecommunication switch (12) to collect various switch and network information and respond with routing recommendations. These routing recommendations are provided in response to a switch utilization index determined for each telecommunication switch (12). The switch utilization index provides an up to date picture of the in service trunks and a realistic figure of the global load on the processors (14). The switch occupancy index is based on trunks, call attempts, time, and switch type and is defined as the ratio of new call arrival rate to the maximum call arrival rate for a dynamically controlled routing processing cycle.

  • Patent number: 5825861
    Abstract: In a telecommunications network of the kind which handles non-time-critical calls (NTCC) in addition to normal telephony, a congestion indication is transmitted to NTCC transmitting platforms if volume and/or rate limit for a particular communications route or switch is exceeded. Transmitting platforms (9,10,11) establish a transmission rate based on a gapping ration (GR). On receipt of a congestion signal the platforms calculate and Inter call delay based on a random number multiplied by a weighting factor determined from the current value of GR. This provides a period during which calls are not attempted after which GR is adjusted using a common ratio to provide a higher value of GR thus transmission rate (or the rate at which calls are offered) to the congestion route is less onerous. Consecutive call failures result in a rapid increase in the value of GR leading to longer ICDs (to allow the congested route/switch to recover) and a lower traffic loading on recovery.

  • Patent number: 5805681
    Abstract: A system for, and method of operation of, estimating a blocking probability for at least a portion of a network and a model of the same are provided. The blocking probability represents a likelihood that a transmitted signal will arrive at least at the portion of the network. The system includes an estimator controller and a processing controller. The estimator controller derives both a direct and an indirect estimator. The direct controller is derived as a function of a number of losses and arrivals occurring with respect to at least the portion of the network during a period of time, and the indirect estimator is derived as a function of an offered load with respect to at least the portion of the network during the period of time. The processing controller, that is associated with the estimator controller, applies a weighting factor to the direct and indirect estimators to derive the blocking probability. The weighting factor minimizes variance of combined estimates.

  • Patent number: 5581610
    Abstract: A method of regulating and managing network traffic at a mediated access service control point in an advanced intelligent switched telephone network that allows a local exchange carrier to monitor and enforce traffic rates negotiated between the local exchange carrier and other third party providers. The invention is implemented at a mediated access service control point in the network, and is activated when a query destined for a third party service control point is generated at a service switching point. The mediated access service control point receives this query and processes the query to determine if the query should be forwarded to the third party service control point. If the query does not violate any of the rates that have been negotiated between the local exchange carrier and the third party, the query is passed from the mediated access service control point to the third party service control point.

  • Patent number: 5521971
    Abstract: A communication network (1) comprises a number of network nodes (2, 3, 4 and 5) linked together by transmission paths (6, 7 and 8). A network manager (9) controls acceptance of calls onto transmission paths by classifying an incoming call and selecting from the database (14) an appropriate mean to peak bit rate distribution. This selected distribution is then used with the monitored transmission path load to determine a posterior distribution which reflects the load. The decision to accept or reject the call is made on the basis of the posterior distribution by a call acceptance algorithm considering the effective bandwidth for example.
