Embodiment Construction

[0025] The main idea of ​​the present invention is: PSTN (Public Switching Telephone Network, Public Switching Telephone Network) fixed telephone has a number, and the set-top box also has a number, and the two numbers of the called user terminal are bound together on the service platform. The calling user terminal is a PSTN fixed phone (of course, it can also be a mobile user), the called user terminal is a PSTN fixed phone and a video communication set-top box, and the calling user terminal calls the PSTN fixed phone or the video communication set-top box of the called user terminal, The call is triggered to the service platform, and the service platform double-calls the PSTN fixed telephone and the visual communication set-top box in the way of simultaneous vibration, and then uses the visual interface of the visual communication set-top box to complete the call transfer function.

[0026] Because of the excellent characteristics of SIP, a phone number is stored in the CONTA...

Abstract

The invention discloses a method and a system of realizing call forwarding employing a set-top box based on SIP protocol. The method comprises the following steps: registering a called visual communication set-top box to an IP multimedia subsystem network, binding the called visual communication set-top box with a called fixed phone; installing a target terminal number of call forwarding corresponding to the called visual communication set-top box and / or the called fixed phone; calling the called fixed phone or the called visual communication set-top box by a calling user terminal and sendinga triggering request to an application server; receiving the triggering request by the application server and calling the called fixed phone and the called visual communication set-top box simultaneously; after receiving the calling by the called fixed phone and the called visual communication set-top box, displaying calling identity delivery by the visual interface of the visual communication set-top box; selecting call forwarding function according to the calling identity delivery by the called visual communication set-top box and forwarding the calling. The invention improves the user experience on the traditional fixed phone business.

Description

technical field [0001] The invention belongs to the field of IMS (IP Multimedia Subsystem, IP Multimedia Network Subsystem), and in particular relates to a method and a system for realizing call forwarding by using a visual communication set-top box. Background technique [0002] IMS is an IP multimedia subsystem. To be precise, IMS is a new core network subsystem after the 3G R5 standard. The IMS is a multimedia call / session control system, and its core key protocols include a SIP (Session Initiation Protocol, Session Initiation Protocol) protocol. IMS is composed of the following entities: Call Server Control Function (Call Server Control Function, CSCF), Home Subscriber Server (Home Subscriber Server, HSS), Subscription Location Function (SubscriptionLocator Function, SLF), Application Server (Application Server, AS), media Gateway Control Function (Media Gateway Control Function, MGCF), IP Multimedia Subsystem-Media Gateway Function (IP Multimedia Subsystem Media Gatewa...
