Embodiment
The embodiment of the present application discloses a kind of call spam means of defence and device, may be used for processing the call spam in existing communication network, and protection user is not harassed by call spam.
Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
A kind of call spam means of defence disclosed in the embodiment of the present application, as shown in Figure 1, comprises the following steps:
S101: from the signaling critical point of communication network, obtains the signaling entering described communication network;
S102: the signaling determining doubtful call spam from described signaling;
S103: by carrying out calling change of address to the signaling of described doubtful call spam, be transferred to call spam end for process, described call spam end for process is used for processing the signaling of call spam and by the signal switching of non-junk phone to called destination party.
Method described in the present embodiment, based on the mode of Signaling Layer calling change of address, forwards doubtful call spam to call spam end for process and processes, because forward based on Signaling Layer, so, be unaware for user, therefore, the normal course of communications of existing communication network can not be affected.
And take over using special call spam safeguard compared with the mode of all calling out, method described in the present embodiment can combine with existing communication network, and replace the existing communication network of adapter without the need to special equipment, therefore, there is the advantage being easy to realize and cost is low.
The embodiment of the present application another call spam means of defence disclosed, as shown in Figure 2, comprises following concrete steps:
S201: signaling sorting end is from the signaling critical point of communication network, obtain enter described communication network, meet pre-conditioned signaling, wherein, pre-conditionedly at least to comprise with the next item down: the user that the user that called party is predeterminable area, called subscriber are preset kind
S202: signaling sorting end determines the signaling of doubtful call spam from above-mentioned signaling, wherein, the signaling of doubtful call spam is the signaling that the communications and liaison credit worthiness of calling party is greater than the first numerical value;
Communications and liaison credit worthiness is the parameter of normal electrical credit household (number) for being used to refer to calling party no.Communications and liaison credit worthiness is higher, and calling party is that the possibility of normal electrical credit household is larger.Communications and liaison credit worthiness can be determined according to calling party call history record in the past.
