Description

Short message management and control system and management and control method of IMS domain
Technical Field
The invention relates to the technical field of communication, in particular to a short message management and control system of an IMS domain and a management and control method applying the system.
Background
Short Message Service sms (short Message Service) is one of the basic telecommunication services of the CS domain, which allows a user to send and receive character information through a short Message center smsc (short Message Service center), and is divided into MO (submit) Message flow and MT (deliverer) Message flow, where the MO Message is a sender user and uploads the Message to a Message center, and the MT Message is a receiver user and sends the Message to the short Message center.
The IP short message sent by the LTE user in the IMS domain is converted into the CS short message through the IP-SM-GW, and the CS short message is stored and forwarded through the SMSC, so that the short message intercommunication of the IMS domain and the CS domain is realized. The IP Short Message gateway IP-SM-GW (IP Short Message gateway) realizes the Short Message intercommunication function of an IMS domain and a CS domain, and provides the function of the Short Message intercommunication with the CS domain terminal for the LTE terminal based on the IP.
In recent years, as criminal fraud means has diversified, short messages have become means that criminals use frequently. Some false advertisements, fraud and pornographic illegal information even cause that many users are cheated, the customer complaints are continuous, and the operator is deeply harmed. With the popularization of intelligent machines, criminals can include short links or complete links downloaded by viruses, trojans and malicious programs in spam short messages for mass sending, and with the evolution of technologies, the anti-detection means similar to harmful short messages is also perfected.
As shown in figure 1, when an SMS over IP realized based on the structure requires terminal registration, an S-CSCF executes third party registration to an IP-SM-GW, and the requirement that an LTE terminal sends and receives traditional short messages through an LTE/EPC network when LTE is attached is met.
The prior art has the following disadvantages:
1. the detection, identification and processing of harmful short messages in the traditional mode mostly depend on the deployment of specific software on short message center equipment for processing, and are limited by service scenes; or the detection reminding is carried out in an APP mode of a third party at the user side of the mobile phone terminal, and a large amount of rubbish or harmful information is transmitted on the telecommunication network depending on the existing data experience, so that precious transmission resources are wasted.
2. The existing network system can not effectively control and process the specific short message service scenes, such as the short message service scenes of roaming users and international roaming users, especially the short message receiving (MT) process of the users.
3. The existing system mostly needs upgrading and modification of network elements for protection of harmful short messages, has low compatibility and network affinity, and cannot be quickly adjusted according to development of telecommunication fraud and other forms.
