A system is described for collecting data records which have been correlated to subscriber, or end user, access network, core network, transport network, and application service information, referred to as end user correlated data records and utilizing those records in a wireless or wireline network to identify and address correctable conditions in a network, such as a wireless or wireline network. The system includes at least one probe in the network which is able to monitor network activity and provide detailed data records on that activity. These data records are sent to a mediation device that correlates those data records with subscriber and/or location data, to create the end user correlated data records. An intelligent application services device takes the end user correlated data records and examines the records to determine if there are any correctable conditions in the network or the end user devices.

System and method of forwarding end user correlated user and control plane or network states to OSS system

A method and apparatus for determining the burst bit rate for data in the transport layer of a network is described. The burst bit rate is determined by measuring the time for a total number of bytes to be transferred across a point in the network and adding that time to an estimated network delay. The total number of bytes transferred is then divided by the transfer time plus the estimated network delay thereby calculating the burst bit rate for the transfer.

Method and system for calculating burst bit rate for IP interactive applications

A system and method for measuring user-perceived delay in an IP network, comprising detecting request and corresponding response messages at a monitoring point in the network, calculating an uplink delay based upon the time elapsed between the request and corresponding response messages, detecting response and corresponding transport acknowledgement messages at the monitoring point, wherein the response message is sent in response to the request message, calculating a downlink network delay based upon the time elapsed between the response and corresponding transport acknowledgement messages; and calculating a user-perceived delay by adding uplink delay and downlink network delay, wherein the user-perceived delay represents a time required for an IP message to travel from a user device to a network destination plus the time required for the service (server) to respond and return the response to the user device.
