CF (Call Forwarding) is a traditional communication service in the telecommunications industry, also known as call forwarding and call forwarding. If you can't answer the phone or don't want to answer it, you can transfer the call to another phone number.

The basic calling service of mobile communication network is the process that the calling user inputs the phone number of the called user, and then the two parties enter the call. However, due to various reasons, if the called user does not receive the incoming call and transfers the incoming call to another phone or number at the same time, it is called CF(Call Forwarding), also known as call forwarding and call forwarding.

The premise of call forwarding service is that the called party B user registers the service in the mobile network. The typical unconditional call forwarding business process is as follows:

The user of calling party A calls the number of called party B, and called party B switches to another number C, and then signs an unconditional contract with the operator. The effect is that when user A calls B, the network makes a judgment according to the subscription information. At this time, user B is no longer paged, but the number of user C is directly connected, and finally the A and C numbers make a two-way call.
