Method for network system of telecommunication operation trader to provide calling transfer for users of other telecommunication network

Abstract

The method is to construct the devices of the call back transferring system. The said devices can be the computer communication system platform, the intelligent network, the next generator network system, IP communication system. The one end of these devices is linked to one network system of the operation dealer through the repeat circuit. The other end of these devices is linked to one network system of the telephone operation dealer the user of the call back transferring telephone belongs to. The said devices provide the functions of the service control, the service data and service exchange. The invention separates apart the call back transferring function of mobile phones and phones of the other telecom from the exchanger in end offices of communication network.

Description

technical field [0001] The invention belongs to communication application technology in the field of communication, in particular to a method for providing call forwarding for telecommunication users of other telecommunication networks by using a network system of a telecommunication operator. Background technique [0002] At present, the call forwarding user of the telephone must first apply to the telephone operator for the call forwarding function, and the telephone operator will input the instruction into the switchboard to activate the call forwarding function of the telephone; the telephone user sets the call forwarding phone on the phone and activates the call forwarding function; The call of the call forwarding telephone is first connected to the end office switch of the call forwarding telephone through the trunk circuit of the communication network. It is not only inconvenient for the user to use call transfer, but also take up twice as many network system resource...

Problems solved by technology

[0003] It can be seen that the existing mobile phone call transfer is attached to the service function of the end office switch of the mobile communication network, and the setting and use method of call transfer are difficult to unify, and the setting is complicated, and the user is difficult to remember, and has the following defects:

[0005] 2. The call transfer realized by the end office switch needs to occupy 2 communication channels (voice channels) of the communication system. Using 2 communication channels to realize a call will take up twice as many system resources, resulting in waste of system resources

[0006] 3. Due to the above "2", the existing call transfer needs to charge two communication fees, that is, the communication fee from the calling phone to the called phone (charged from the calling phone), and the communication fee from the called phone to the actual call connection. Communication fee for the number (phone number to which calls are forwarded) (paid by the phone where call forwarding is set)

[0007] 4. China currently charges two-way charges for mobile phone users' communications, and one-way charges for fixed-line calls

[0010] 6. Due to the reas
