Embodiment 1

[0058] In this preferred embodiment, a home voice communication gateway is provided, a system composed of a voice communication gateway and a terminal that can be deployed on the home gateway, and the home gateway accesses the IP Multimedia Network Subsystem (IP Multimedia Subsystem, referred to as IMS) provides a voice call method for terminals. Through the above method, the terminal can switch the call to other calling devices in the home network through the home gateway within the coverage of the home network, and these devices can also be connected to the session together, turning the one-to-one voice call into a conference call .

[0059] The method of this preferred embodiment includes the functional module division and framework of the voice call gateway in the home gateway, the interaction mode between the terminal and the voice gateway in the home gateway, the method for switching the voice call of the terminal between the mobile cellular network and the fixed network...

Embodiment 2

[0066] Figure 13 is a schematic diagram of a voice switching process according to Embodiment 2 of the present invention, such as Figure 13 As shown, in this embodiment, the terminal in the local area network has established an IMS voice call with a terminal in another external network. The terminal may be connected to an LTE network, or may be connected to an IP network by other types of networks. At this point, if the terminal finds an available wireless local area network, it initiates a wireless local area network access procedure. WLAN access involves interaction with the access control module of the home gateway. The content of the interaction includes access control to terminals, IP address allocation, hierarchical processing of multiple service flows, and so on. After the terminal accesses the WLAN, it wishes to continue the previous IMS voice call through the WLAN. At this time, the terminal initiates a call switching request to the voice gateway module, requesting...

Embodiment 3

[0074] Figure 15 is a schematic diagram of a call transfer process according to Embodiment 3 of the present invention, as Figure 15 As shown, it is assumed that Terminal 1 and Terminal 2 are both connected to the wireless local area network, and Terminal 1 is conducting an IMS voice call with Terminal 1 in the external network. At this time, terminal one sends a call transfer request (SIP Refer) message to the voice gateway module, and transfers the voice call to terminal two. After the voice gateway module accepts the transfer request, it sends a call request (SIP Invite) to Terminal 2. After receiving the call request, Terminal 2 initiates (SIP reInvite) to the opposite end of the call to re-negotiate the media. After the renegotiation is successful, the call transfer can be regarded as successful, and at this time, a call end message and a call status notification message are sent to Terminal 1.

Abstract

The invention discloses a home gateway, a voice communication method and a voice communication apparatus. The home gateway includes a voice communication gateway which is connected with a first terminal in a local area network inside the home gateway and an IMS core network outside the home gateway and is used for establishing a voice communication connection between the first terminal in the local area network inside the home gateway and a second terminal of the IMS core network outside the home gateway. With the home gateway, the voice communication method and the voice communication apparatus of the invention adopted, the problem of singleness of modes of the access of a terminal to an IMS to realize voice communication in the prior art can be solved, and the flexibility of the access of the terminal to the IMS to realize voice communication can be improved, and user experience can be enhanced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a home gateway, a voice call method and device. Background technique [0002] Home Gateway (Home Gate Way) is a device that realizes the communication between various devices in the home network and external devices, and is the core component of the home network. Cisco's definition of a home gateway is: an intelligent gateway between networked information devices in the home and an intelligent broadband access network. Through the devices in the home network, information can be exchanged with the telecommunication network, and information can also be exchanged between internal devices. [0003] For users, with the popularization of high-speed broadband Internet access and home computers, more and more digital multimedia devices such as notebook computers, digital TVs, mobile phones, fixed phones and other consumer electronics products often need to pass through the network at t...
