The network architecture that the embodiment of the present invention relates to can be as shown in Figure 1, and terminal 1 and terminal 2 can be the terminals of one family or belong to campus, a factory etc.; Terminal 3 belongs to the terminal of another family, campus or factory.Terminal 1 and terminal 2 can by wired or be wirelessly connected on Access Network terminal equipment 4.Access Network terminal equipment 4 can pass through IP Multimedia System (IP Multimedia Subsystem, IP Multimedia System) 5 and connect terminal 3.Wherein, terminal 1 can be the equipment of support voice business, such as POTS(Plain Old Telephone Service, Plain Old Telephone Service) terminal, terminal 2 can be support the equipment of audio frequency and video business, such as smart mobile phone, PAD, intelligent television, PC etc.
Access Network terminal equipment 4 can be optical network unit (Optical Network Terminal, ONT), router, home gateway etc.
Based on above-mentioned framework, one embodiment of the invention provides a kind of voice and video telephone method, and the method provided can be switched in terminal 2 to carry out voice and video telephone under terminal 1 and terminal 3 are in voice-frequency telephony state.
As shown in Figure 2, the method provided comprises:
Step 200, terminal 1 sends handover request to Access Network terminal equipment 4.
In the present embodiment, Access Network terminal equipment 4 is each terminal distribution intercom number of one family, each terminal is registered on Access Network terminal equipment 4 respectively by intercom number, multiple terminal is shared unified POTS number and is realized outcall and receive calls, and adopts the intercom number of distribution to communicate between terminal and between terminal with Access Network terminal equipment.
In the present embodiment, terminal 1 is carried out in the process of voice-frequency telephony, if need to increase video calling, then sends handover request to Access Network terminal equipment 4, carries the intercom number for the terminal switched in handover request.In the present embodiment, terminal 2 supports audio frequency and video ability, and terminal 1 is for being switched in terminal 2, then terminal 1 carries the intercom number of terminal 2 to the handover request that Access Network terminal equipment 4 sends.
Wherein, handover request can be dialogue-based initiation protocol (Session Initiation Protocol, SIP), and such as Invite message etc., the intercom number of terminal 2 can be carried in the To header field of Invite message.
Step 210, Access Network terminal equipment 4 sends call request to terminal 2.
IP address and the port information of distant end media is carried in the call request that Access Network terminal equipment 4 sends.In the present embodiment, Access Network terminal equipment 4 is as RTP (Real-Time Transport Protocol, RTP) act on behalf of, then Access Network terminal equipment 4 is by voice wide area network (the Wide Area Network of RTP agency on this equipment, WAN) the IP address of mouth and the port information of voice WAN mouth send to terminal 2 as the IP address of distant end media and port information, terminal 2 makes a call according to the IP address of distant end media and port information or answers the call, and completes RTP agent process by Access Network terminal equipment 4.
Step 220, Access Network terminal equipment 4 receiving terminal 2 answer message, the IP address of terminal 2 is arranged in the IP address of user side media in being acted on behalf of by RTP.
After step 210 and 220, between Access Network terminal equipment 4 and terminal 2, just can send voice RTP Media Stream.
Step 230, the renewal media request of Access Network terminal equipment 4 receiving terminal 2, is transmitted to terminal 3 to increase video by renewal media request.
The media update request of terminal 2 can be the Invite message based on SIP, and the From header field in Invite message can the intercom number of carried terminal 2.
After Access Network terminal equipment 4 receives the media update request of terminal 2, after converting the intercom number in the From header field in media update request to unified outside number, be transmitted to terminal 3.
Step 240, the voice and video telephone between described terminal 2 and terminal 3 acted on behalf of by Access Network terminal equipment 4 after described terminal 3 accepts described renewal media request.
