Description

Short message management and control system and 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

The short message service SMS (Short Message Service) is one of basic telecommunication services of the CS domain, and allows a user to send and receive character information through the short message center SMSC (Short Message Service Center), and is divided into an MO (subscriber) message flow, an MT (delivery) message flow, in which an MO message uploads a message to a message center for a sender user, and an MT message sends a message to a receiver user for the short message center.

The IP short message sent by the LTE user in the IMS domain is converted into a 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 the IMS domain and the CS domain, and provides the function of short message intercommunication with the CS domain terminal for the LTE terminal based on IP.

In recent years, as criminals' fraud approaches are diversified, short messages are also becoming a common approach for criminals. Some false advertisements, fraud and pornography illegal information even cause that many users are cheated, customer complaints are continuous, and operators are also deeply harmed. Along with the popularization of intelligent machines, criminals can include short links or complete links downloaded by viruses, trojans and malicious programs into spam messages for mass sending, and along with the development of technology, the anti-detection means similar to harmful messages are also continuously perfected.

In the prior art, as shown in fig. 1, when the SMS over IP realized based on the architecture requires terminal registration, the S-CSCF executes third party registration to the IP-SM-GW, thereby meeting the requirement that the LTE terminal sends and receives traditional short messages through the LTE/EPC network when the LTE terminal is attached.

The prior art has several disadvantages:

1. the detection, identification and processing of the harmful short messages in the traditional mode mostly depend on the deployment of specific software on the short message center equipment for processing, and are limited by service scenes; or detecting and reminding in a third party APP mode at the mobile phone terminal user side, and depending on the existing data experience, a large amount of garbage or harmful information is transmitted on a telecommunication network, so that precious transmission resources are wasted.

2. The existing system of the current network is used for realizing effective management and control processing of specific short message service scenes, such as roaming users, international roaming users and the like, particularly the received short messages of the users, namely MT flow.

3. The existing system needs upgrading and reconstruction of network elements for the protection of harmful short messages, has low compatibility and network affinity, and cannot be quickly adjusted according to the development of forms such as telecom fraud and the like.
