Video.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of VoLTE user with solid based on the VoLTE network architecture
The solution of network users one-way video call, makes VoLTE user when fixed network user initiates video calling, and fixed network user can borrow
The Internet is helped to receive the video information of VoLTE user.
The technical scheme is that video call method between a kind of VoLTE and PSTN net, described call method is based on existing
There is VoLTE network structure, utilize the ATCF transfer control module of IMS AS application server and inside thereof and ATGW to shift gateway
Module, is provided with a network element video acquiring method, when VoLTE user initiates video calling to fixed network user, by audio stream
It is sent to fixed network user's terminal, video flowing is sent to by the Internet the streaming media server in high in the clouds, make fixed network user receive
While voice, can be by wired, wireless or WIFI accesses the Internet and receives video information, and network element video acquiring method is:
1) fixed network user can be authenticated by IMS AS application server, identifies whether fixed network user registers use and receive VoLTE user
Video call function, is designated as VPVC (VoLTE PSTN Video Call) function, and fixed network user can register Shen at operator
Please VPVC function；
2) ATCF transfer control module (Access Transfer Control Function) is according to IMS AS application server
VPVC function request, instruction ATGW transfer gateway module (Access Transfer Gateway) transfer gateway module separate
Send audio stream, video flowing；
3) ATGW transfer gateway module accepts the instruction of ATCF transfer control module, by audio streams to fixed network user's terminal,
Video flowing is sent to high in the clouds streaming media server by the Internet；
4) high in the clouds streaming media server can receive ATCF transfer control module send video flowing carry out being stored or sent to network
Terminal；
5) network terminal user can be authenticated by high in the clouds application server, and the network terminal will be indicated from high in the clouds streaming media service
Device obtains video；
6) APP based on systems such as android/ios application, user can be regarded from the acquisition of high in the clouds streaming media server by this application
Frequency stream.
There is advantages that
1) present invention need not increase any new equipment in existing VoLTE EPS, only special network element need to be increased software function.
2), during video information of the present invention is stored in high in the clouds streaming media server and application server, it is not take up the network terminal and appoints
What resource.
3) user of the present invention only needs registration terminal application can obtain video, it is not necessary to other any operations.
Detailed description of the invention:
Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
The present invention is video call method between a kind of VoLTE and PSTN net, and described call method is based on existing VoLTE network
Structure, utilizes the ATCF transfer control module of IMS AS application server and inside thereof and ATGW to shift gateway module, is provided with
One network element video acquiring method, when VoLTE user initiates video calling to fixed network user, uses audio streams to fixed network
Family terminal, is sent to the streaming media server in high in the clouds by video flowing by the Internet, while making fixed network user receive voice, and can
By wired, wireless or WIFI accesses the Internet and receives video information, and network element video acquiring method is:
1) fixed network user can be authenticated by IMS AS application server, identifies whether fixed network user registers use and receive VoLTE user
Video call function, is designated as VPVC (VoLTE PSTN Video Call) function, and fixed network user can register Shen at operator
Please VPVC function；
2) ATCF transfer control module (Access Transfer Control Function) is according to IMS AS application server
VPVC function request, instruction ATGW transfer gateway module (Access Transfer Gateway) transfer gateway module separate
Send audio stream, video flowing；
3) ATGW transfer gateway module accepts the instruction of ATCF transfer control module, by audio streams to fixed network user's terminal,
Video flowing is sent to high in the clouds streaming media server by the Internet；
4) high in the clouds streaming media server can receive ATCF transfer control module send video flowing carry out being stored or sent to network
Terminal；
5) network terminal user can be authenticated by high in the clouds application server, and the network terminal will be indicated from high in the clouds streaming media service
Device obtains video；
6) APP based on systems such as android/ios application, user can be regarded from the acquisition of high in the clouds streaming media server by this application
Frequency stream.
Call flow of the present invention is:
1.VoLTE terminal use initiates visual telephone to fixed network user.
2., during call is set up, IMS AS application server carries out function authentication to called fixed network user, if quilt
It is user registered VPVC function of having opened, then sends VPVC request (request includes the information such as called number) to ATCF and shift
Control module.
After 3.ATCF transfer control module receives the VPVC request of IMS AS application server, with the streaming media service in high in the clouds
