Description
Technical field
The present invention relates to the communications field, method, device and the attack protection system in particularly a kind of location IMS (IP Multimedia System, IP Multimedia System) network attack source.
Background technology
Along with popularizing of Internet, the IP technology has obtained application more and more widely.At wireless communication field, 3G receives increasing concern as Internet especially in the expansion of wireless domain.The maker 3GPP of 3G standard (3rd GenerationPartnership Project, third generation partner program) has proposed the notion of IMS in Release 5 versions, formally IP is defined as the bearer network of the following core net of 3G.On this basis, ETSI (European Telecommunications StandardsInstitute, ETSI) etc. organize and proposed FMC (Fixed Mobile Convergence, fixing merge with moving) notion, will fix with the mobile core network unification to IMS.Thereby established IMS in the absolute leadership status that does not fix with mobile core network.
Because the bearer network of IMS is IP, so IMS has also inherited IP network problem under attack easily.Under present circumstances, the PC that a Daepori is logical can send tens thousand of attack messages each second, and this is enough to cause the nucleus equipment among the IMS to be busy with handling attack message, and request stops response to normal users.Typical dos attack that Here it is.
At dos attack, the most effective way is exactly to dispose attack-prevention-device at the core net edge, as fire compartment wall or SBC (Session Border Controler, Session Border Controller) with anti-attack ability.Particularly SBC equipment because have signaling, media processing capacity, so can not only resist the dos attack of IP layer, can also be resisted signaling and Media layer dos attack.Even but disposed fire compartment wall or SBC means as attack protection, can only obtain assailant's source IP address, owing to can't orient the physical location of attack, thereby the generation that can't stop to attack from root, network still can take a large amount of network bandwidths because of attack message, causes regular traffic quality deterioration even interruption.Therefore basic solution is to find out the source of attack as early as possible, cuts off the root of attacking, and guarantees professional normally carrying out.But because the IP address is often by the Dynamic Host Configuration Protocol server dynamic assignment in the IP network, thus by the IP address be can't consumer positioning physical location.
Summary of the invention
Can't be in order to overcome in the prior art by IP address location user's physical location, thus the shortcoming of the generation that can't stop to attack from root, and the embodiment of the invention has proposed method, device and the attack protection system in a kind of IMS of location network attack source.
The described technical scheme of the embodiment of the invention is as follows:
