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 1: mirroring the network traffic of the MGCF and P-CSCF ports on the IMS network switch;

[0040] Step 2: Stripping the Ethernet frames in the mirrored flow data sequentially 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 3: parse the SIP message according to the standard SIP protocol, extract the metadata (calling ID, calling number, called number, etc.) from the header field of the SIP message, and...

Embodiment 2

[0055] like 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 noti...

Abstract

The invention discloses a method and system for instantly notifying missed calls of multiple accounts in an IMS network, and the method comprises the steps: sequentially stripping Ethernet frames in mirror image flow data on an IMS network switcher, and obtaining an SIP message; analyzing the SIP message, extracting the calling identifier, the calling number and the called number from the head domain of the SIP message, and storing the calling number and the called number into a memory queue after duplicate removal; and obtaining the calling number and the called number from the memory queue,and if the called user subscribes the missed call instant notification service, sending a notification message to notify the user in time. According to the invention, missed calls in the IMS administrative switching network can be processed immediately, and telephone terminal users are no longer restricted by fixed-line telephones; aiming at a single-user multi-account communication system, integration notification is carried out; only services are provided for subscribers, invalid notifications are avoided, and server resources are saved; the content of the notification message is detailed information, thereby facilitating the instant processing of 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 ...
