A voice over long-term evolution (VoLTE) is a high-speed wireless communication standard for mobile phones and data terminals, and the VoLTE is based on an Internet Protocol (IP) multimedia subsystem (IMS) network, and a configuration file specially made for a Control Plane (CP) and a Media Plane (MP) of a voice service is used in the LTE network as a data stream to be transmitted in the LTE data bearer network, so that a high-quality voice communication service can be established by effectively using a bandwidth. Based on the characteristics of large bandwidth and high rate of VoLTE, the terminal can already realize high definition video call (ViLTE) at present, and the video call between the terminals can be realized without installing additional software.
As shown in fig. 1, an embodiment of the present invention provides a communication architecture, which includes a terminal 01, a network device 02, and a service device 03.
The terminal 01 can perform data interaction, voice call or video call with other communication devices. Terminal 01 may be a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent or user equipment, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a terminal in a 5G network or a terminal in a future evolved Public Land Mobile Network (PLMN) network, etc.
The network device 02 can provide data transmission services for other communication devices and establish a call connection for them. The network device 02 may be a communication device provided by a telecom operator, such as an independent processing device, and can process and forward a call request of the terminal 01; also, for example, an apparatus is composed of an IMS network device, a Mobility Management Entity (MME), a Home Subscriber Server (HSS), and the like.
The service device 03 may provide content services, such as voice services or video services, for other communication devices. The service device 03 may be a server used by a content service provider to provide content services, such as one server in a server cluster (composed of multiple servers), a chip in the server, a system on chip in the server, or implemented by a Virtual Machine (VM) deployed on a physical machine.
According to the communication architecture, the embodiment of the invention provides a video on demand method, which can realize video on demand through a VoLTE function of a terminal. As shown in fig. 2, includes:
s101, the terminal sends an INVITE message to the network equipment.
The INVITE message is used for requesting video, and comprises a service equipment identifier and a video identifier.
Specifically, the terminal may be the terminal 01 shown in fig. 1. In the embodiment of the invention, the INVITE message is a request message sent by the terminal to the network device when the terminal actually initiates a call request. The sending procedure of the INVITE message may be: a terminal calls a dialing function of a User Interface (UI), and a calling number is input into the dialing interface; when the terminal dials the calling number, the terminal sends an INVITE message to the network device, and the INVITE message realizes the calling of the terminal. It should be noted that the number carried in the INVITE message is different from the number carried in the INVITE message in the normal call request, and the INVITE message is used for video on demand, so the number carried in the INVITE message may be composed of a service device identifier and a video identifier.
Illustratively, the number dialed by the terminal in the embodiment of the present invention is different from a normal telephone number, where the number dialed by the terminal may be composed of the service device identifier and the video identifier, for example, the number dialed by the terminal may be 1218800001, where 12188 is the service device identifier and 00001 is the video identifier. Of course, 1218800001 is merely exemplary, and the number dialed by the terminal may be different depending on the service device identification and the video identification. For example, when the service device identifier is 12189 and the video identifier is 02222, the number dialed by the terminal may be 1218902222, i.e., the INVITE message includes 1218902222. The service device identifier and the video identifier are only exemplary, and in practice, the service device identifier and the video identifier are not limited to 5-bit components, and those skilled in the art may set the service device identifier according to the number of the service devices and set the video identifier according to the number of the videos, which is not limited in the embodiment of the present invention.
It should be noted that, the process of the terminal initiating the dialing request may be realized not only by the terminal user manually dialing through the dialing function of the terminal, but also by the terminal calling the dialing function by scanning the two-dimensional code, for example, the two-dimensional code includes the bracket code 1218902222, the terminal may scan the two-dimensional code to call the dialing function, and the called dialing interface has already input the number 1218902222. Of course, the terminal user may also implement the process of the dialing request by other methods, which is not limited in this embodiment of the present invention.
S102, the network equipment receives the INVITE message sent by the terminal.
Specifically, the network device may be the network device 02 shown in fig. 1. In a possible implementation, the network device may be a separate processing device provided by a telecommunications carrier; in another possible implementation, the network device may also be composed of multiple entity devices provided by a telecom operator.
The network device may be a processing device provided by a telecommunications carrier and located in a core network, and may receive a call request initiated by a terminal and process the call request. Of course, the network device may also be composed of multiple entity devices provided by a telecommunications carrier, such as a proxy-call session control function (P-CSCF), an interrogating-call session control function (I-CSCF), a serving-call session control function (S-CSCF), and an HSS, and the multiple entity devices process a call request initiated by a terminal.
S103, the network equipment sends a video request message to the service equipment corresponding to the service equipment identification.
Wherein the video request message includes a video identification.
Specifically, the service device here may be the service device 03 shown in fig. 1. In a possible implementation manner, if the network device is an independent processing device provided by a telecom operator, the network device may obtain the service device identifier carried by the network device by parsing the INVITE message. The network device may store a correspondence between the service device identifier and the service device, where the correspondence includes the service device identifier, the service device, and the service device address, as shown in table 1 below:
TABLE 1
Service device
Service device identification
Service device address

167.192.134.124
Service equipment four
16531
167.192.134.129
…
…
…
As shown in table 1 above, if the network device determines that the service device identifier carried in the INVITE message is 12188, the corresponding service device is a first service device, and the address of the first service device is 137.163.127.184, the network device may send a video request message to the first service device according to the address of the first service device, where the video identifier carried in the video request message is the video identifier in the INVITE message. The video request message is used for acquiring a video stream address of a video corresponding to the video identifier.
In an optional implementation manner, the telecommunications carrier may further provide a storage device, where the storage device is configured to store a correspondence between the service device identifier and the service device. After obtaining the service device identifier, the processing device may query the storage device for the address of the corresponding service device.
In another possible implementation manner, if the network device is composed of a P-CSCF, an S-CSCF, and a DNS, as shown in fig. 3, the process of the network device processing the INVITE message includes:
s201, the terminal sends an INVITE message to the P-CSCF.
Wherein the INVITE message includes a service device identification and a video identification.
And S202, the P-CSCF sends an INVITE message to the S-CSCF.
Specifically, the S-CSCF here is the S-CSCF to which the terminal belongs, and the S-CSCF is already determined when the terminal performs authentication registration, and the determination process of the S-CSCF is not described herein again.
S203, the S-CSCF sends a domain name resolution request message to a domain name server DNS.
The domain name resolution request message at least comprises a service equipment identifier.
Specifically, after the S-CSCF receives the INVITE message, it may determine a number consisting of a service device identifier and a video identifier, such as 1218902222, by parsing the INVITE message. The S-CSCF may send the serving device identifier to a Domain Name Server (DNS), and the DNS server determines an address of the serving device corresponding to the serving device identifier.
Certainly, the domain name resolution request message may further include a video identifier, and the S-CSCF may send both the service device identifier and the video identifier to the DNS, but the DNS only queries the service device identifier to determine the address of the service device corresponding to the service device identifier.
And S204, the DNS returns a domain name resolution response message to the S-CSCF.
Wherein the domain name resolution response message includes an address of the serving device.
Specifically, the DNS stores therein a correspondence between an address of the service device and an identifier of the service device. The DNS may determine the address of its corresponding service device according to the service device identifier in the domain name resolution request message, such as service device identifier 12189, and its corresponding service device address may be 137.164.127.187.
S205, the S-CSCF sends a video request message to the service equipment.
Wherein the video request message includes a video identification.
Specifically, after receiving the domain name resolution response message, the S-CSCF may determine an address of the service device corresponding to the service device identifier, and send a video request message to the service device, where if the address of the service device is 137.164.127.187, the S-CSCF may send the video request message to the service device with the address of 137.164.127.187, and request the service device to return a video stream address of a video corresponding to the video identifier.
It should be noted that the above-mentioned network device is composed of a P-CSCF, an S-CSCF, and a DNS only for example, and in practice, the network device may further include other core network entity devices provided by a telecommunications carrier, such as an HSS, which is not limited to this embodiment of the present invention.
And S104, the network equipment receives the video stream address sent by the service equipment and sends the video corresponding to the video identifier to the terminal according to the video stream address.
Wherein, the video stream address is the storage address of the video.
Specifically, when the network device is an independent processing device, the service device may receive a video request message sent by the processing device; when the network device is composed of a P-CSCF, an S-CSCF and a DNS, the service device can receive a video request message sent by the S-CSCF.
The service device stores the corresponding relationship between the video identifier and the video stream address, as shown in table 2 below:
TABLE 2
Video identification
Video stream address
00001
rtsp://137.164.127.187/vod/mp4:00001
00002
rtsp://137.164.127.187/vod/mp4:00002
00003
rtsp://137.164.127.187/vod/mp4:00003
…
…
As shown in the above table, if the video identifier is 00001, the video stream address corresponding to the video identifier is rtsp://137.164.127.187/vod/mp4:00001, and after the service device determines the video stream address corresponding to the video identifier, the service device may send the video stream address to the network device. It should be noted that when the network device is a stand-alone processing device, the video stream address may be sent to the processing device; the processing device can download the corresponding video according to the video stream address, encode the downloaded video, and send the encoded video to the terminal. When the network equipment consists of the P-CSCF, the S-CSCF and the DNS, the service equipment can send the video stream address to the S-CSCF; and the S-CSCF downloads the corresponding video according to the video stream address, codes the downloaded video, and sends the coded video to the terminal through the P-CSCF.
It should be noted that the network device performs video encoding in a segmented manner, that is, a complete video is divided into a plurality of video segments, the network device encodes the plurality of video segments to obtain a plurality of encoded video data, and the plurality of encoded video data are sequentially sent to the terminal. The encoding process of the video by the network device in this embodiment is the same as that of the video encoding process in the prior art, and is not described herein again. The video downloaded by the network device according to the video stream address may be stored locally in the service device or in the cloud server, which is not limited in the embodiment of the present invention. When the video is stored locally in the service equipment, the network equipment downloads the video from the service equipment; and when the video is stored in the cloud server, the network equipment downloads the video from the cloud server according to the video stream address.
In an alternative, the service device may also send video to the network device instead of the video streaming address. Certainly, when the service device sends the video to the network device, the service device also needs to split the video into a plurality of video segments, encode the plurality of video segments, and then send the encoded video segments to the network device.
S105, the terminal plays the video sent by the network equipment.
The video is the video corresponding to the video identifier, and the video is the video stored by the service device corresponding to the service device identifier.
Specifically, the terminal may receive a plurality of video segments which are sent by the network device and subjected to encoding processing, decode the plurality of video segments which are subjected to encoding processing by the terminal to obtain a plurality of video segments which are split by a video, and play the plurality of video segments.
It should be noted that the terminal needs to play the video segments according to the sequence of the video segments, so as to implement complete playing of the video.
The video on demand method provided by the embodiment of the invention realizes video on demand through the dialing function of the terminal, reduces the process that the current terminal realizes video on demand by depending on video APP, and saves the memory resource of the terminal; and the video on demand is realized through the dialing function of the terminal, so that frequent operation during the video APP on demand is avoided, and the video on demand flow is simplified.
Optionally, the INVITE message further includes a terminal identifier. As shown in fig. 4, before step S103, the method further includes:
s301, the network equipment determines that the terminal has opened the video-on-demand service according to the terminal identification.
Specifically, the terminal identifier may be an International Mobile Subscriber Identity (IMSI) of the terminal. The HSS is used to store subscription data of the terminal in the communication network provided by the telecommunications carrier. Therefore, in this step, no matter the network device is an independent processing device or a device composed of P-CSCF, S-CSCF, and DNS, the network device can query the HSS according to the terminal identifier, thereby determining whether the terminal activates the video on demand service.
It should be noted that, when the network device is an independent processing device, the processing device may query the HSS for the subscription data of the terminal, so as to determine whether to activate the video on demand service; when the network device is composed of a P-CSCF, an S-CSCF and a DNS, the subscription data of the terminal can be inquired and completed from the HSS by the S-CSCF. Of course, in an alternative implementation, the network device may include an HSS in addition to the P-CSCF, the S-CSCF, and the DNS.
Optionally, as shown in fig. 5, before step S103, the method further includes:
s302, if the network equipment determines that the terminal does not open the video-on-demand service, a rejection message is returned to the terminal.
The reject message is used for indicating that the terminal does not open the video on demand service.
Specifically, if the network device does not inquire the information of the terminal subscribed video on demand service when inquiring the HSS according to the terminal identifier, it is determined that the terminal does not open the video on demand service. At this time, the network device returns a rejection message to the terminal, indicating that the terminal does not open the video-on-demand service.
It should be noted that, because the video on demand of the embodiment of the present invention is implemented by the terminal through the dialing function, the rejection message returned to the terminal by the network device may be a voice message, for example, after the terminal receives the rejection message, the voice message "you have not opened the video on demand service" is played. Certainly, after determining that the terminal does not open the vod service, the network device may hang up the call request of the terminal, and send a short message to the terminal to indicate that the terminal does not open the vod service, where the content of the short message may be "you have not opened the vod service.
In the embodiment, the network equipment divides the terminal into the terminal which opens the video on demand service and the terminal which does not open the video on demand service according to the terminal identification, and when the terminal does not open the video on demand service, the terminal is limited to carry out video on demand, so that the terminal can be effectively managed and classified.
Optionally, the video request message may further include a terminal identifier, and the service device may further store a correspondence between the terminal identifier and the member level, as shown in table 3 below:
TABLE 3
Terminal identification

…
…
…
As shown in the above table, after the service device obtains the terminal identifier by parsing the video request message, the service device may determine the member level of the corresponding terminal according to the terminal identifier, where if the terminal identifier is 460030912121023, the member level of the terminal corresponding to the terminal identifier is a golden member. Of course, the service device may also classify the video corresponding to the member level of the terminal, such as setting the video as a free video, a member video, and the like. When the terminal is a common member, only free videos can be requested, if the videos requested by the terminal are member videos, the service equipment sends a response message to the network equipment, and the response message is used for indicating that the member level of the terminal does not have the authority of playing the corresponding videos; when the terminal is a golden member, the terminal can not only order free videos, but also order member videos.
It should be noted that the response message sent by the service device to the network device may be sent to the terminal by the network device, and the process of sending the response message to the terminal by the network device is consistent with the process of sending the reject message to the terminal, and both may be implemented by a voice message and a short message, which are not described herein again. When the terminal plays the video, the video may include advertisement content, and the silver member is set only to cancel the advertisement when the terminal plays the video, and does not have the right to request the member video. It should be understood by those skilled in the art that when a general member requests video, the free video played by the general member may include advertisements, and when a golden member requests video, the member video (free video) played by the golden member does not include advertisements. The member level and the corresponding authority are only exemplary, and those skilled in the art can modify the member level and the corresponding authority as required, and the embodiment of the present invention is not limited thereto.
According to the embodiment, the on-demand permission is distributed to the terminal according to the member grade of the terminal, the income increase of a telecom operator can be realized, and the personalized customization of the on-demand service of the terminal is realized.
Optionally, when the terminal interrupts playing the video on demand (for example, hangs up a call), the terminal may send a play suspension message to the network device, so as to instruct the terminal to suspend playing of the video. The play abort message may include a video play node, where the video play node is configured to indicate a time point of video play, such as video play to 00: 05: 13, namely when the video is played for 5 minutes and 13 seconds, the terminal hangs up the call, and the video playing node records as 00: 05: 13. after receiving the play suspension message, the network device may send a play recording message to the service device, where the play recording message includes a video play node. After receiving the play record message, the service device may store the video play node, the video identifier, and the terminal identifier, and establish a correspondence relationship between the terminal identifier, the video identifier, and the video play node, as shown in table 4 below:

As shown in table 4, when the terminal initiates a call request again, if the call request of the terminal is the same as the call request of the last time, and if the INVITE message includes the number 1218800001, the service device, after receiving the video request sent by the network device, first queries the correspondence between the terminal identifier, the video identifier, and the video playing node stored in the service device. If the corresponding relation stores the terminal identification carried in the video request message, inquiring whether the terminal plays the video with the video identification of 00001 according to the terminal identification; and if the terminal plays the video corresponding to the video identifier, determining a video playing node of the video. After determining the video playing node, the service device may send a video stream address of the video to the network device, where the video stream address carries the video playing node. When the network equipment downloads the corresponding video according to the video stream address, the network equipment can skip the video data before the video playing node, encode the video data after the video playing node and send the encoded video data to the terminal. When playing the encoded video data, the terminal can skip the video playing in the time period before the video playing node, thereby realizing that the terminal continuously plays the played video according to the playing record.
The embodiment can enable the terminal to realize continuous playing of the played video according to the playing record, avoid the terminal from repeatedly playing the same content, and save the time for the terminal user to watch the video.
