Description

Method and device for call transfer

Technical field

This application relates to, but is not limited to, the field of communications.

Background technique

With the development of wireless communication technology, the use of mobile terminals is more and more extensive, and call forwarding as an additional service for calls also plays an important role in some occasions. For example, when the user does not bring a mobile phone, if the call forwarding is to be initiated, the operator's customer service must be called and the user password provided. If the user does not remember the password, the service cannot be transferred before the call is opened, and thus the important call may be missed.

The precondition for implementing call forwarding service in the network is that the called party first signs the service in the mobile network. When the calling user calls the called user, the network judges according to the subscription information. If the called party goes to the third party number before the operator signs the call, the called party will directly answer after the long ringing, the network will directly Continue to the third party, and finally realize the call between the calling party and the third party. For the technology of implementing the call forwarding service, the technology is completely dependent on the operator. If the user does not open the call forwarding service for the terminal at the operator beforehand, when the user does not carry the terminal, the terminal does not automatically transfer after the call is made. Receiving a third party may result in missed calls. In addition, if the user wants to remotely open the terminal call forwarding function, the user password must be provided to the operator. If the user does not remember the password and has no real-name authentication, the user cannot implement the call forwarding service.

Therefore, the related technical solution is completely dependent on the operator, and when the user does not carry the terminal, the user can only open the call transfer service by providing the operator with the user password.
