Description
Technical field
It is the invention belongs to telecommunications network junk call processing technology field, in particular to a kind of based on media redirection of router
Junk call identification device and protective device and method can be realized anti-to the telecommunication call progress harmful information carried based on IP
Shield, suitable for the junk call detection identification and protection soft switch, IMS network.
Background technique
Junk call refer to by telecommunication network carry out, to seize economic interests or certain other interests as mesh
, unrelated with normal communications traffic or information interchange flame activities of transmission, mainly include telecommunications, financial swindling phone and
Illegal sales calls etc..According to the statistics made by the departments concerned, the junk call number for generating or receiving every year in China's public telecom network at present
In terms of hundred million, a large amount of fraud case is thus caused, has been brought seriously to the personal safety and safety of property even civil order of the people masses
It threatens, also becomes the malignant tumor for restricting the benign development of China's telecommunications industry.Ministry of Industry and Information, China, Ministry of Public Security etc. pay much attention to junk call
Protected working, in recent years since take many measures from publicity, management and technology etc. respectively.In the main of technological layer
Means include: 1) exhaled using the black and white lists of switching equipment, designated user's number or object code limit, the functions such as 'no disturbance ' service it is real
Apply protection；2) intelligent transfer platform is set, the incoming call business of quasi- protection user is transferred to the platform by switching equipment and implements inspection
Survey protection；3) the entrance trunk of quasi- protection telecommunication network is all directly linked into junk call guard system and implements inspection
Survey protection etc..These methods can solve the protection question of junk call to a certain extent, but there is also certain limitation,
Be mainly reflected in: first two method is required to switching equipment and is cooperated, the functional performance of protective capacities and switching equipment itself
Correlation, and do not have the active analysis ability to new junk call source, new under fire user；Later approach is in administrative electricity
It when communication network range is larger, needs to access a large amount of trunk, and with the flattening of telecommunication network framework and controls and hold
Load mutually separates, and the construction scale and cost of this method sharply increase, and greatly reduce its feasibility.
Currently, the networking model of the tandem step by step gradually logout based on traditional TDM exchange, major operator use control with
Isolated flexible exchanging network framework is carried, with the construction and development of 4G network, IMS core network construction has also been opened up comprehensively
It opens.For the flattening network architecture carried based on IP, a kind of junk call means of defence is needed, can be avoided current telecommunications net
The problem of junk call is taken precautions against, as far as possible reduction soft switch/IMS network harassing call quantity.
Summary of the invention
For this purpose, the present invention provide it is a kind of based on the junk call identification device and protective device of media redirection of router and side

For the media IP of protective device, (main session signaling includes the main session such as INVITE, 180/183, UPDATE, 200OK, ACK
Process messages)；
Implementation steps (three): after signaling level IP modification, the both call sides of request are initiated as UE#1 and UE#2 is received
Opposite end media IP is the media IP of protective device.When subsequent UE#1 and UE#2 carries out call media content interaction, the calling
Calling and called Content of Communication is drawn the multi-media processing unit that is connected to protective device, and (unit will be in media in a manner of internuncial
Hold and deliver communicating both sides)；
Implementation steps (four): to Content of Communication (text, voice, image, view on the dedicated multimedia unit of protective device
Frequency etc.) it is detected, after being found to be junk call, it is reported and is disposed.
In the embodiment of the present invention, system is serially connected in signaling backbone transport route and is routed by the media updated in signaling
To be detected to Content of Communication, and then junk call is managed, there are the covert properties such as equipment is stealthy, address is passive,
Acquisition and storage across media can also be carried out to the Content of Communication of sensitive target；Based on control plane signaling concatenation, user face matchmaker
Body redirection of router realizes that telecommunications network junk call protects purpose, and junk call in current telecommunications net can effectively be avoided to protect
The situations such as existing at high cost and feasibility is low substantially reduce harassing call quantity in soft switch and IMS network, improve communication network
User satisfaction in network.
