The application provides an abnormal call identification method, device, equipment, medium and program product, and relates to the technical field of communication, to solve the problem of low accuracy in identifying abnormal calls. The method comprises the following steps: obtaining a session initiation protocol (SIP) signaling of a voice over IP (VoIP) call based on a target interface, wherein the target interface is an interface between a mobile wireless network and a core network; analyzing the SIP signaling to obtain the bearing content corresponding to the SIP signaling; and determining whether the voice call corresponding to the SIP signaling is an abnormal call based on the bearing content. The application can improve the accuracy of identifying abnormal calls and accurately identify abnormal calls.

A method and system for routing a communication using a communication system between a first participant device, on an Internet Protocol (IP) network, associated with a first participant, and a second participant device associated with a second participant. The method involves receiving a second participant identifier associated with the second participant device, causing the at least one processor to access a user profile that is specific to the first participant, performing a comparison of the second participant and at least one first participant attribute associated with the user profile, determining whether at least one route exists to the second participant device using a first type of communication or a second type of communication based on route information, including an Internet Protocol (IP) address of a suitable communication network element, and establishing the communication to the second participant. The system may utilize Public Switched Telephone Network (PSTN) compatible numbers to identify route information.

A system and method for processing Voice over Internet Protocol (VoIP) traffic flows, particularly encrypted VoIP traffic flows, on a computer network. The method includes collecting traffic flow data for IP sessions, collecting parameters associated with the IP sessions, determining whether the IP sessions are VoIP sessions, correlating IP sessions having similar parameters with the collected parameters, and creating at least one Internet Protocol Detail Record (IPDR) or Call Detail Record (CDR) based on the correlated IP sessions. The system includes a collection module configured to collect traffic flow data, an analysis module configured to determine the parameters and determine whether the IP sessions are VoIP sessions, and a correlation module configured to correlate IP sessions having similar parameters and create at least one Internet Protocol Detail Record (IPDR) or Call Detail Record (CDR) based on the correlated IP sessions.

The system obtains multiple thresholds for multiple bandwidth usage types associated with a UE. The threshold indicates an amount of bandwidth available to the UE over a predetermined period. Each threshold corresponds to a bandwidth usage type. The multiple thresholds include: roaming data, home data, voice over IP, international voice over IP, roaming voice over IP, international data, and tethering data threshold. The system obtains multiple bandwidth usage patterns of the UE, where each bandwidth usage pattern corresponds to a threshold. The system iterates over each bandwidth usage to determine whether the UE has exceeded or is likely to exceed the threshold within the predetermined period. Upon determining that a bandwidth usage pattern has exceeded or is likely to exceed the threshold within the predetermined period, the system determines an increase to the threshold. The system sends an indication of the increase to the threshold to the UE.
