Embodiment 1

[0038] refer to figure 1 , an instant notification method for multi-account missed calls in an IMS network, comprising the following steps:

[0039] Step S1: mirroring the network traffic of the MGCF and P-CSCF ports on the IMS network switch;

[0040] Step S2: sequentially stripping the Ethernet frames in the mirrored traffic data to obtain IP packets, UDP packets, and SIP packets in sequence.

[0041] Specifically, the acquired mirrored traffic is transmitted in the form of Ethernet frames at the link layer, extracting the data part of the Ethernet frame is the IP message transmitted at the network layer, and then extracting the data part of the IP message is the transmission Layer UDP message, and finally extract the data part of the UDP message to get the application layer SIP message.

[0042] Step S3: parse the SIP message according to the standard SIP protocol, extract the metadata (call ID, calling number, called number, etc.) from the header field of the SIP message, ...

Embodiment 2

[0055] Such as figure 2 As shown, a multi-account missed call instant notification system in an IMS network includes: an IMS network switch, a missed call server, and a user terminal device;

[0056] Copy the port traffic of the IMS network element P-CSCF (Proxy Call Session Control Function) and MGCF (Media Gateway Control Function) on the IMS network switch in the IMS core network to a designated port through port mirroring technology, and the missed call The server collects and analyzes traffic data from the specified port, and analyzes the SIP packets in the mirrored traffic of the IMS network switch; extracts the call ID, calling number, and called number from the header field of the SIP packet, and saves the primary The calling number and called number are stored in the memory queue; the calling and called numbers are obtained from the memory queue, and if the called user subscribes to the instant notification service of missed calls, a notification message is sent to n...

Abstract

The invention discloses an instant notification method and system for multi-account missed calls in an IMS network. The Ethernet frames in the mirrored traffic data on the IMS network switch are stripped sequentially to obtain SIP messages; the SIP messages are analyzed, and the SIP messages are obtained from The header field extracts the call ID, calling number, and called number. After deduplication, save the calling number and called number in the memory queue; obtain the calling and called numbers from the memory queue. If the called user subscribes to the Receive an instant notification service for incoming calls, and send notification messages to notify users in a timely manner. Missed calls in the IMS administrative switching network of the present invention can be processed immediately, and telephone terminal users are no longer bound by fixed telephones; integrated notifications are performed for single-user multi-account communication systems; services are only provided for subscribers, avoiding invalid notifications, Save server resources; the content of the notification message is detailed information, which is convenient for the immediate processing of the office staff.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for instant notification of multi-account missed calls based on user identities in an IMS network. Background technique [0002] The IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) is an IP-based network system architecture for providing services such as audio and multimedia services. As the development core of the Next Generation Network (NGN), IMS can realize functions such as conference calls, video conferences, real-time messages and multimedia services. With the continuous improvement of IMS technology, the construction and use of the IMS system network in the administrative switching network is becoming more and more mature, but there are still some deficiencies in some aspects. [0003] At present, the IMS administrative office network is mainly used for daily landline telephone business. When the user leaves the office, it is impossible ...
