Detailed Description

The present application will be described in further detail with reference to the accompanying drawings and examples.

Video telephony (MultiMedia Telephony, MMTel) is an IP multimedia system (IP Multimedia Subsystem, IMS) based multimedia telephony service standard developed jointly by two large standardization organizations, ETSI/TISPAN and third generation partnership project (3rd Generation Partnership Project,3GPP), a global standard specification supporting telecommunications operators to evolve traditional circuit switched services into internet protocol (Internet Protocol, IP) based real-time multimedia telephony services, including voice and video calls, messaging services, video image sharing, etc., while supporting fixed and mobile broadband access.

Fall back: taking a Voice over Long Term Evolution (VoLTE) video telephony as an example, the service fallback related scheme has a standby circuit switched (Circuit Switched Fallback, CSFB) and a Voice service continuity (Single Radio Voice Call Continuity, SRVCC). CSFB is a technique to provide voice continuity services that allows UEs in a group core evolution (Evolved Packet Core, EPC) network to fall back to the circuit switched domain (Circuit Switched Domain, CS), which provides voice to end users. SRVCC is a VoLTE voice service continuity scheme proposed by 3GPP, and is mainly used for solving the problem of ensuring voice call continuity when a single radio frequency UE (User Equipment, UE) moves between a Long Term Evolution (Long-Term Evolution) network and a second generation mobile communication technology (Second Generation, 2G)/third generation mobile communication technology (3rd Generation,3G) CS network, i.e., ensuring smooth handover between IMS-controlled internet voice (Voice Over Internet Protocols, voIP) and CS domain voice.

Digital person: a digital character image which is close to the human image and is created by using digital technology. The reference to a digital person in this patent is to be understood as an Avatar (Avatar) of a user in the virtual world of the real world, which Avatar may be driven by the user to act in place of the user in the virtual world, including a conversation and related action.

The existing implementation scheme of the service is as follows: in the video call process, a user moves to a place with a bad signal and falls back to the voice call, so that the user cannot see the video as long as any party has a bad signal, and both parties are voices.

The common feature of CSFB and SRVCC is that the network without video transmission capability is directly switched to voice service, and the one-sided video can not be continued under the condition that the signal of one terminal is not good and the other air interface bandwidth or access network supports video capability.

Based on the above, in various embodiments of the present application, a digital man device is introduced, and a voice media channel is established between a terminal incapable of carrying a video call and the digital man device, so that the terminal incapable of carrying the video call receives voice information; and establishing a video media channel between the terminal capable of carrying the video call and the digital personal equipment so that the terminal capable of carrying the video call receives video information, and realizing that if one terminal signal is not good, the other terminal can continue to carry out unilateral video under the condition of supporting video capability by an air interface bandwidth or an access network.

As an example, the first terminal may be a calling terminal corresponding to a calling subscriber, and the second terminal may be a called terminal corresponding to a called subscriber; or the first terminal may be a called terminal corresponding to a called user, and the second terminal may be a calling terminal corresponding to a calling user; in practical applications, the calling terminal may be referred to as a calling terminal a; the called terminal may be referred to as called terminal B.

In step S101, when the first terminal and the second terminal perform video call, it may be understood that when the first terminal and the second terminal initiate video call or when the first terminal and the second terminal perform video call. Specifically, when the first terminal of the first user and the second terminal of the second user initiate the video call or when the first terminal of the first user and the second terminal of the second user perform the video call. Wherein, the first user and the second user can be determined according to actual situations, which is not limited herein. As an example, the first user may be a calling user and the second user may be a called user; alternatively, the first user may be a called user, and the second user may be a calling user; in practical applications, the calling subscriber may be referred to as caller a; the called user may be referred to as called user B.

As an example, the access network connection status is monitored in real time during the initiation and progress of the video call between user a and user B.

In step S102, determining whether the first terminal and the second terminal can carry a video call based on the resource information may be understood as determining whether the first terminal and the second terminal can carry a video call based on the resource information, so as to obtain a determination result that the first terminal cannot carry a video call or the first terminal cannot carry a video call; the first terminal cannot carry the video call can be understood as that the first terminal cannot carry the video call, and the second terminal can carry the video call; the fact that the second terminal cannot carry the video call can be understood that the first terminal can carry the video call, and the second terminal cannot carry the video call.

Establishing a voice media channel between a terminal incapable of carrying a video call and digital personal equipment can be understood as establishing a voice media channel between the terminal and digital personal equipment to perform single-side voice if a terminal signal of one party is not good and cannot carry a video call.

Establishing a video media channel between a terminal capable of carrying video calls and the digital personal device can be understood as establishing a video media channel between the terminal and the digital personal device for single-side video if the other party terminal has good signals and can carry video calls.

As an example, the connection status of the access network is monitored in real time during the initiation and progress of the video call between the user a and the user B; the network judges whether the network resources accessed by the calling party and the called party can not bear the video call, if so, the network falls back to the voice; if not, the access network resource does not support the video call to one party to trigger the audio operation digital person, and the video call is continued with the other side after the audio is overlapped with the digital person image subscribed on the network side.

For example, the invitation information may be a ReINVITE/200 message; the UPDATE information may be an UPDATE/200 message. The media path request information may also be a media path anchor request.
