Problems solved by technology

However, the SCTP protocol cannot completely avoid the abnormal access of illegal signaling. How to realize the security protection of user information for the signaling network and prevent the abnormal access of illegal signaling will be an important part of ensuring the security of the mobile communication network.
[0003] At present, the access mode of the No. 7 signaling network security protection equipment based on the packet domain is to access the live network with a real identity, and it is located between the No. 7 devices at both ends. After the received data is processed, it is then forwarded to the No. 7 device at the other end, which changes the network topology of the signaling network, which is of great interest to mobile operators.
Moreover, when the protective device exits, the link of the No. 7 device at both ends will be disconnected, which will cause a sense of network equipment, which will seriously affect the normal operation of the business.
[0004] According to the above analysis, the access and exit of the existing packet domain signaling network security protection equipment cannot be completely insensitive to the network, so the security effect of equipment concealment cannot be achieved.

Abstract

The invention discloses a non-inductive series connection device based on the virtual IP. The non-inductive series connection device is used for being connected with a signaling network safety protection device to be connected in series and is connected with the signaling network safety protection device through a standard IP stack. The non-inductive series connection device comprises a front board plug, a rear board plug and a processing unit, wherein the front board plug is connected with the rear board plug through a back plate bus, and the processing unit is in communication connection with the front board plug; in the working process, a virtual address layer conducts source address analysis and recording operation and target address analysis and recording operation on information of data inputted by an internet access A and / or an internet access B, and therefore the data can pass through an SC. It is ensured that the safety protection device can not affect the normal network service even under the condition of equipment faults, and hidden access and hidden quit of the device are achieved. When the non-inductive series connection device is obtained, the related safety protection device can complete the service operation such as detection, cutting, blocking and filtering of abnormal signaling under the hidden condition, and safe delivery of mobile communication network signaling information is ensured.

Description

technical field [0001] The invention relates to a non-inductive serial connection device based on virtual IP. Involves patent classification number H04 Electric communication technology H04L Transmission of digital information, such as telegraphic communication H04L12 / 00 Data exchange network H04L12 / 02 Parts and components H04L12 / 24 Devices for maintenance or management. Background technique [0002] At present, the SIGTRAN protocol is mainly used to transmit No. 7 signaling on the IP network. The signaling transport layer defined in the SIGTRAN protocol uses the SCTP protocol. SCTP is a connection-oriented transport layer protocol that uses flow control similar to TCP and The congestion control algorithm ensures reliable transmission of user data between two SCTP endpoints through its own confirmation and retransmission mechanism. Compared with other transmission protocols such as TCP, SCTP has a small transmission delay, which can avoid some large data from blocking other...
