In order to make the above-mentioned objects, features and advantages of the present disclosure more easily understood, specific embodiments of the present disclosure will be described in detail with reference to the accompanying drawings below. Apparently, embodiments described below are merely a portion of embodiments of the present disclosure, and are not all embodiments. All other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of the present disclosure, based on embodiments disclosed hereinafter.
A method for call forwarding applied to a called party terminal is provided in the present disclosure. Referring to
In S11, a call request is received.
In S12, a call forwarding request made by a user is received, where a call forwarding destination number is carried in the call forwarding request.
In S13, a response message containing the call forwarding destination number is transmitted to a network side, so that the network side can forward the call request to a terminal corresponding to the call forwarding destination number according to the response message.
A method for call forwarding, applied to a network side device, is provided according to embodiments of the present disclosure. Referring to
In S21, a response message containing a call forwarding destination number is received.
In S22, a call request is forwarded to a terminal corresponding to the call forwarding destination number according to the response message.
The method for the call forwarding in the present disclosure will be described below in specific embodiments.
In some embodiments, a calling party terminal B transmits a call request to a called party terminal A, regardless of the called party terminal A is in an idle state or in a call state, if a user of the terminal A chooses to forward the call request to a user of a terminal C, the terminal A may enter a number of the terminal C or select the number of the terminal C from contacts, and click a forwarding button on an interface, then a signaling will be send to a network, where the signal contains the number of the terminal C and a message indicating forwarding.
Specifically, the terminal A may send a 486 signaling to a network. In the 486 signaling, the following header fields are also carried in addition to the basic header fields.
History-info: A number; C number Reason:
sip; text=“call is being forwarded”
The History-info header field indicates to the network that the terminal A requires forwarding the current call request to the terminal C. The Reason header field carries information indicating forwarding, where the signaling in which the terminal A notifies the network of call forwarding is not limited to the 486 signaling, and the header fields are also not limited to the History-info head field and the Reason header field, and may be any signaling or header field that can indicate to the network that the call needs to be forwarded.
After receiving the 486 signaling from the terminal A, the network detects a cause value of “call is being forwarded” in the Reason header field, and determines that the call needs to be forwarded; and further acquires the number of the terminal C to be forwarded to from the History-info header field. Then the network forwards the call request sent by the terminal B to the terminal C and transmits a 181 signaling to inform the terminal B that the call is forwarded to the terminal C.
The method for call forwarding provided according to the embodiments of the present disclosure can forward the incoming call to any number selected by the user in real time by transmitting the call forwarding destination number selected by the user to the network side. Compared with the conventional technology, flexibility of call forwarding can be improved in the present disclosure.
