BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The technical solution of the present invention can be applied to various Internet communication systems.

The user equipment in the embodiment of the present invention may be a mobile terminal (Mobile Terminal), a mobile user equipment, or the like, and one or more through an IP (Internet Protocol) via a radio access network (eg, RAN, Radio Access Network). The core network communicates, and the user equipment can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile phone function, for example, It can be a portable, pocket, handheld, computer built-in or in-vehicle mobile device that can exchange language and/or data with the wireless access network. In addition, the user equipment may also be a soft terminal, that is, various computers capable of making a call by IP.

In view of the problem of inconvenience to the user in the absence of the call forwarding function, the embodiment of the present invention provides the following methods and apparatus.

1 is a flow diagram of a method 10 of call forwarding in accordance with an embodiment of the present invention. Method 10 can be implemented by a device such as a mobile terminal or a soft terminal.

As shown in Figure 1, it includes:

11 . Presenting a call-on interface after the call is successfully established with the first user equipment, where the call-on interface 0 includes the first input area.

After the second user equipment successfully establishes a call with the first user equipment, the call setup interface is presented. The second user equipment may be the calling party, and accordingly, the first user equipment is the called party; the second user equipment may also be the called party, and accordingly, the first user equipment is the calling party.

13. When receiving the first input to the first input zone, presenting a call forwarding interface, the call forwarding interface includes a second input zone and a third input zone.

15: When receiving a second input to the second input zone and a third input to the third input zone, sending a transfer request to the switch, so that the switch establishes a call between the first user equipment and the third user equipment, The transfer request includes an identifier of a third user device carried by the second input. The third input refers to an input for selecting an identifier for calling the third user equipment.

In the embodiment of the present invention, the identifier of the third user equipment is different according to the type of the third user equipment or the system in which the third user equipment is located. For example, when the third user equipment is a mobile phone, the identifier of the corresponding third user equipment may be The phone number of the third user device; when the third user device is a soft terminal (such as a SIP terminal), the identifier of the third user device may also be the user name of the third user device. It can be understood that the identifier of the third user equipment can be input by the user through the identifier input button provided by the call forwarding interface. 5 For example, the telephone number corresponding to the third-party user equipment can be input by inputting a numeric button of the telephone number; The identifier of the third-party user equipment may be selected from the identifier book stored in the second user equipment by the identifier selection button provided by the user through the call forwarding interface, where the identifier book may be a different name according to the identifier. For example, it may be a phone book in a mobile phone, an address book in a soft terminal, etc.; for example, when the second user device is a mobile phone, it may be selected from a phone book stored in the mobile phone. Select the phone number corresponding to the third user device.

The second user equipment transfers the call established with the first user equipment to a third party, that is, a third user equipment in the context.

After the switch establishes a successful call between the first user equipment and the third user equipment,

5 The switch-on interface is further included, and the switch-on interface includes a call-on state indication of the third user equipment and a fourth input area for selecting to terminate the call with the first user equipment. The call-on status information of the call between the first user equipment and the third user equipment obtained by the second user equipment may be sent by the switch. The call-on status indication displayed on the transfer-on interface may be a text mode, a picture mode, or a combination of text and pictures.

In addition, before the switch establishes a successful call between the first user equipment and the third user equipment, a transfer waiting interface may be presented, and the transfer waiting interface includes a fifth input area for canceling call transfer and call forwarding. An indication that the call is in progress. For example, you can display a calling third-party device by using a combination of text, or picture, or text and picture on the transfer waiting interface.

Before the switch establishes a successful call between the first user equipment and the third user equipment, the switch may also be in the form of a transfer ringing interface, and the transfer ringing interface includes a fifth input area for canceling call transfer and call forwarding. Connect to the indication of the ringing state. For example, a third-party device can be ringing in the transfer ringing interface using text, or a picture, or a combination of text and pictures.

Before the switch establishes a successful call between the first user equipment and the third user equipment, the handover busy interface may also be presented, and the handover busy interface includes a fifth input area »0 for canceling call forwarding. Call forwarding is an indication that the line is busy. For example, you can display the third-party device line busy in the transfer busy interface by using text, or picture, or a combination of text and picture.

In the embodiment of the present invention, the second user equipment can select a call forwarding option during the call, input or select the identifier of the third party, and select to call the identifier, thereby implementing a call with the third party, thereby solving the problem that the mobile user equipment or the soft terminal cannot be The inconvenience caused by call forwarding is more convenient and convenient for the transfer industry.
