Problems solved by technology

The disadvantages of the existing technology are: in order to effectively restrict illegal incoming calls, it is necessary to upgrade the software on all gateways in the network and make a black and white list, which consumes huge manpower, material resources and time costs, and cannot restrict some special prefixes, which is not conducive to future maintenance

Embodiment Construction

[0011] A preferred embodiment of the present invention will now be described in detail in conjunction with the accompanying drawings.

[0012] see figure 2 The network architecture diagram for the implementation of the present invention is shown, wherein, GMSC / TMSC triggers all incoming calls between networks to SCP according to the relay source; reports different service keys according to different relay sources; SCP, through the signaling network Complete the signaling interaction with GMSC / TMSC, determine the relay source of incoming calls between the networks according to the MSC ID and service key of the gateway office / tandem office; intercept the confirmed false calling numbers between the networks.

[0013] The specific steps of this method are as follows: step 1, the gateway office GMSC / tandem office TMSC receives the inter-network call request initiated by the user, triggers the IDP to the SCP according to the relay source, and reports different service keys in the I...

Abstract

The invention discloses a method for monitoring an internetwork fake calling number, and belongs to the technical field of wireless communication. The method for monitoring the internetwork fake calling number comprises the following steps: 1) GMSC / TMSC receives an internetwork calling request sent by a subscriber and triggers an initialized trigger point IDP to an SCP according to a trunk source, and the IDP reports different business keys; and 2) the SCP judges an internetwork calling number according to a set principle and releases the calling if judging the calling number is an illegal number, and if not, the SCP identifies an internetwork calling trunk source according to MSC ID of a gateway exchange / tandem exchange and the business keys, matches with a preset black / white list, releases the calling if the calling number does not appear in the white list but appear in the black list, and normally continues the calling if the calling number does not appear in the black list but appear in the white list. The method has the advantages of low investment cost and small implementation risk.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method for monitoring false calling numbers between networks. Background technique [0002] With the development of telecom value-added services, operators have leased relay resources to various independent platforms to carry out value-added services. Due to the lax management and constraints, these platforms connected to the mobile gateway office and the tandem office often change the calling number to make the mobile phone receive free calls when interoperating between networks, such as figure 1 As shown, in this way, illegal VoIP services or some business promotions related to their own interests will be carried out, which will cause loss of call fees to mobile operators. At present, measures to standardize incoming calls between networks are mainly to set up black and white lists on the gateway office, and restrict calls to irregular calling numb...
