Method and system for centralized sorting of IMS telephone terminal call records

Abstract

The invention discloses an IMS telephone terminal call record centralized sorting method and system. The method comprises the following steps: forwarding flow data on a network switch port where a core network element P-CSCF and an AGCF of an IMS are located to a specified port through a mirror image; stripping the SIP message from the flow data packet; and analyzing the SIP message, extracting akey field from the SIP message, integrating corresponding call records through the key field, and sorting out the call records of the IMS telephone terminal. According to the invention, the call records of the IMS telephone terminal can be sorted in real time, and support is provided for call record query service.

Description

technical field [0001] The invention belongs to the technical field of communication networks, and in particular relates to a centralized sorting method and system for IMS telephone terminal call records. Background technique [0002] The traditional enterprise administrative switching network is mainly based on circuit switching, providing high-quality communication services such as voice and transmission for daily administrative work. With the continuous development of IP and other packet technologies, program-controlled switching devices based on circuit switching technology gradually show technical deficiencies. With the continuous increase of business, the existing program-controlled equipment is increasingly unable to meet the needs of development. In recent years, IMS (IP Multimedia Subsystem) technology has been promoted throughout the country. IMS adopts the all-IP SIP (Session Initiation Protocol) protocol, which supports rich IP multimedia services. [0003] The...

With the continuous increase of business, the existing program-controlled equipment is increasingly unable to meet the needs of development. In recent years, IMS (IP Multimedia Subsystem) technology has been promoted throughout the country. IMS adopts the all-IP SIP (Session Initiation Protocol) protocol, which supports rich IP multimedia service

[0003] The existing IMS system can meet the normal call needs of enterprise employees, and the call records can be parsed from the bill file generated by the IMS system, but the call records parsed are generally the records of completed calls, and there are no records of unconnected calls, and From the completion of the call to the generation of the records in the bill file, and then to the parsing of the call records, the real-time performance is insufficient, and it is impossible to realize real-time services such as instant pop-up notifications for incoming calls and reminders for missed calls.
