Problems solved by technology

However, it is up to the operator to notify the forwarded party. The area under the jurisdiction of each operator is not exactly the same, and the number of each user terminal number belongs to the operator is also different, and different operators cannot be arbitrarily Obtain data such as log files of the other party. The problem with this method is that it can only limit the call transfer scenario of the user terminal number in a certain area, and there is no way to solve the problem of cross-region and cross-operator malicious call transfer.
[0005] In summary, the drawback of the call transfer method in the prior art is that it has strong limitations

Embodiment 1

[0017] Embodiment 1 of the present invention proposes a call transfer method here, such as figure 1 shown, including:

[0018] Step 11: Receive an incoming call to the first user terminal number, and determine whether the incoming call to the first user terminal number needs to be transferred to the second user terminal number. If the judging result is yes, step 12 is executed; otherwise, the incoming call is connected to the first user terminal number.

[0019] Wherein, the first user terminal number is the call forwarding user terminal number, and the second user terminal number is the called forwarding user terminal number. By setting call forwarding on the terminal, the user can transfer the incoming call of the first user terminal number to the second user terminal number for answering. The terminal set by the user may be, but not limited to, a dual-mode terminal, a single-mode terminal or a multi-mode terminal. If the user is setting up a dual-mode terminal, the first...

Embodiment 2

[0056] Further, on the basis of the above-mentioned first embodiment, the second embodiment of the present invention here proposes a call transfer method. In the second embodiment of the present invention, it is assumed that the user terminal number A calls the user terminal number B, and the user terminal number B calls Carry out call forwarding, the call is forwarded to the user terminal number C, the user terminal number C has customized the call forwarding and interception service, that is, the user terminal number C has registered the function of call forwarding notification and call interception, and the user terminal number C is stored in the HLR on the network side. The called party subscription information of terminal number C subscribes to the call forwarding interception service in the SCP. After the call transfer of user terminal number B, when user terminal number A calls user terminal number B for the first time, the call is passed, and the service control node (S...

Embodiment 3

[0073] Further, on the basis of the first embodiment above, a call transfer method is proposed in the third embodiment of the present invention. In the third embodiment of the present invention, assuming that the user terminal number A calls the user terminal number B, the user terminal number B will call Carry out call transfer, transfer the incoming call to the user terminal number C, the user terminal number C has customized the call transfer interception service, that is, the user terminal number C has registered the function of call transfer notification and call interception, and it will be stored on the network side and in the HLR There is the called subscription information of the user terminal number C, and the call forwarding and interception service is subscribed in the SCP. After the call transfer of user terminal number B, when user terminal number A calls user terminal number B for the first time, after the call is passed, the network side receives the reply from ...

Abstract

The invention discloses a call transfer method and device. The method includes: when it is necessary to transfer an incoming call to a first user terminal number to a second user terminal number, determining whether the second user terminal number is customized with call transfer interception Service; when it is determined that the second user terminal number is customized with a call forwarding interception service, it is judged whether this call forwarding is the first time that the incoming call of the first user terminal number is transferred to the second user terminal number; in the judgment result If yes, transfer the current incoming call to the number of the first user terminal to the second user terminal. By adopting the technical scheme proposed here in the present invention, the applicability of the call forwarding service can be better improved, and the accuracy of blocking malicious call forwarding can be improved.

Description

technical field [0001] The present invention relates to the field of core network technology, in particular to a call transfer method and device. Background technique [0002] Call forwarding is a basic service of the communication system. When a certain user terminal number (called the forwarding party) cannot answer the incoming call or it is inconvenient to answer the incoming call, the incoming call can be transferred to another user terminal number (called the forwarding party) through setting. on the transferred party). At present, call forwarding can be set on the user terminal to transfer its own incoming calls to the user terminal of other numbers. This method does not need the consent of the transferred party when setting the call transfer, which saves the setting time of the transferred party. However, in this call transfer method, there are also criminals who maliciously transfer their incoming calls to the terminal corresponding to any random number. If the tr...
