Description

Method and device for sending video short message

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for sending a video short message.

Background

The multimedia message is a message form developed on the basis of short message service, and uses WAP (Wireless application Protocol) as a carrier to transmit information such as pictures, sound, video, characters and the like. The multimedia message distribution platform generally comprises an operator, a Content Provider (CP) and a Service Provider (SP).

The traditional multimedia message service support capacity is generally less than or equal to 300KB, and usually only comprises pictures and characters, which makes the display form of the multimedia message too single. However, with the network technology, the number of users is greatly increased, and the users have higher and higher requirements for colorful and diversified display forms of information. If the multimedia message service is required to be various in implementation form and content, the size of the multimedia message greatly exceeds 300KB, and the multimedia message becomes a large-capacity video short message. With the development of terminal technology, the mobile phone can completely support large-capacity multimedia messages at present, and can achieve better message presentation effect through the large-capacity multimedia messages, thereby realizing the application in the fields of enterprise marketing, information release, policy publicity, travel popularization and the like.

Currently, a large-capacity video short message is sent by adopting an exclusive bandwidth mode, and if the transmission rate is calculated according to the exclusive bandwidth of a 100M optical fiber, the downloading speed can reach 12.8 MB/S. Assuming that the average capacity of the video short messages is calculated according to 2MB, the unique bandwidth of the 100M optical fiber can only support the video short message concurrent rate of 6 pieces/second.

However, the multimedia message service is a service with mass sending property, and the characteristic that only 6 video messages can be sent in parallel per second greatly limits the development of the multimedia message service.

In summary, there is no scheme capable of supporting a large number of parallel sending of large-capacity video short messages in the prior art.

As shown in fig. 2, an embodiment of the present invention provides a system for sending a video short message, where the system includes:

the short message platform 100 is used for generating a video short message to be sent to a terminal; sending the video short message to be sent to the terminal to a content delivery server in the CDN, so that the content delivery server sends the video short message to the CDN edge platform, sending platform information of the CDN edge platform determined by a balanced load system according to the position of the terminal to the terminal, and obtaining the video short message from the corresponding CDN edge platform by the terminal according to the platform information.

The CDN edge platform 102 is used for sending a downloading instruction of the video short message to the terminal after receiving the video short message sent by the content delivery server, wherein the video short message is generated by the short message platform and needs to be sent to the terminal; and if the terminal which does not download the video short message exists in the terminals which need to receive the downloading instruction after the set period is reached, sending the downloading instruction of the video short message to the terminal which does not download the video short message.

The terminal 103 is configured to receive a download instruction of a video short message sent by the CDN edge platform; downloading the video short message from a CDN edge platform; the video short message is generated by a short message platform and is sent by a content delivery server and a CDN edge platform.

The short message platform in the system generates a video short message to be sent to the terminal and sends the video short message to be sent to the terminal to a content delivery server in the CDN; and then, the content delivery server sends the video short message to the CDN edge platform, and the CDN edge platform sends the video short message to the terminal. Therefore, the content of the large-capacity video short message can be released to the CDN edge platform closest to the terminal by adding a new network architecture in the existing network technology, so that the terminal can obtain the required content nearby, the response speed of the user for downloading the content is improved, the issuing arrival rate is greatly improved, and the single information capacity can be greatly improved.

The video short message is information which is formed by combining part or all of contents such as pictures, characters, videos, animations, two-dimensional codes, hyperlinks and the like.

The scheme of the embodiment of the invention will be explained with reference to the specific examples.

When the embodiment of the invention is implemented, firstly, a short message platform generates a video short message which needs to be sent to a terminal; sending the video short message to be sent to the terminal to a content delivery server in the CDN, so that the content delivery server sends the video short message to the CDN edge platform, sending platform information of the CDN edge platform determined by a balanced load system according to the position of the terminal to the terminal, and obtaining the video short message from the corresponding CDN edge platform by the terminal according to the platform information.

In specific implementation, before the short message platform generates the video short message to be sent to the terminal, a target terminal needing to send the video short message needs to be determined.

First, the following description will be made with respect to a target terminal that the short message platform determines needs to send a video short message.

In specific implementation, a video short message sent to a terminal as required can be used for planning a region range expected to be sent, and then the terminal for receiving the video short message is determined in the determined region range.

Optionally, for any video short message, the short message platform determines a candidate terminal for receiving the video short message according to user population attribute tag information and user position information corresponding to the terminal;

and the short message platform selects a terminal positioned in a white list from candidate terminals for receiving the video short message as a terminal for receiving the video short message.

According to the method, the short message platform determines candidate terminals needing to send the video short messages according to the user population attribute label information and the user position information corresponding to the terminals provided by the base station, and then selects the terminals located in the white list from the candidate terminals receiving the video short messages as the terminals receiving the video short messages. Therefore, compared with the prior art that only multimedia messages are sent in a group mode without screening the received terminals, the embodiment of the invention can only send the video messages to the determined terminals needing to send the video messages, avoids causing troubles to users who do not need to receive the video messages, and improves user experience.

In specific implementation, a regional intelligent platform in a short message platform screens out a target population according to an application field and population attributes, and the regional intelligent platform processes IMSI data subjected to encryption desensitization for the sake of confidentiality; and then, the big data center platform in the short message platform decrypts the screened encrypted IMSI data to obtain a candidate target terminal for receiving the video short message.

The user population attribute label information includes, but is not limited to, age, gender, regular population or floating population, tourist, and the like.

The user position information refers to longitude and latitude information of the user position. The position information of the user is determined by the call record, the internet access record and the like of the base station at the terminal.

In specific implementation, when data interaction exists between the terminal and the base station, the base station can position the terminal according to the data interaction record between the terminal and the base station.

The candidate terminals receiving the video short messages, which are determined by the short message platform according to the user population attribute label information and the user position information corresponding to the terminals, are all terminals meeting big data statistics in a determined area range, and at the moment, the determined terminals are wide and need to be further determined according to a preset white list.

And when determining that candidate terminals receiving the video short messages, which are determined according to the user population attribute label information and the user position information corresponding to the terminals, belong to the same white list, determining that the terminal is the terminal receiving the video short messages.

Further, after the short message platform determines a terminal for receiving the video short message according to the user population attribute tag information, the user position information and the white list corresponding to the terminal, the short message platform also adjusts the determined terminal for receiving the video short message according to a preset black list and a red list, and simultaneously adjusts the determined terminal for receiving the video short message through the black list and the red list.

Optionally, the short message platform removes terminals located in a blacklist from terminals receiving the video short messages and/or places terminals not in the terminals receiving the video short messages and located in a red list in terminals receiving the video short messages.

According to the method, after the short message platform determines the terminal for receiving the video short message according to the user population attribute label information and the user position information corresponding to the terminal, the terminal which is positioned in a blacklist and/or the terminal which is not positioned in the terminal for receiving the video short message and is positioned in the terminal for receiving the video short message is also removed from the terminal for receiving the video short message. Therefore, the finally determined terminal for receiving the video short message can be more accurate.

When the video short message is sent, the corresponding blacklist and the corresponding red list are set manually; and for the blacklist, setting that the video short message is not sent to the terminal in the blacklist under any condition; for the red list, it is set that the terminal must be guaranteed to receive the video short message under any condition.

The blacklist and the blacklist can be set according to requirements corresponding to different services, and are not necessarily set.

Secondly, the short message platform determines a terminal needing to receive the video short message according to the method, generates the corresponding video short message according to the content needing to be sent, and processes the generated video short message.

In specific implementation, the short message platform first generates a corresponding video short message according to the input content of the original material for generating the video short message. Further, after the short message platform generates the video short message, the video short message is processed to a certain extent, so that the video short message can be displayed on the terminal.

When the short message platform processes the video short message, the quality inspection of the generated video short message is needed firstly.

Optionally, the short message platform filters the generated video short message according to the set keyword and the sensitive word bank.

In specific implementation, the short message platform filters the generated video short message according to the set keyword and the sensitive word bank, so that the sent video short message can be ensured not to relate to social sensitivity, and social security is prevented from being influenced.

Further, when the short message platform filters the generated video short message according to the set keywords and the sensitive word bank, the text content in the generated video short message is compared with the set keywords, and the video short message containing the keywords in the keywords is intercepted; or replacing keywords contained in the keywords appearing in the video short message by special symbols; and/or comparing the text content in the generated video short message with a set sensitive word bank, and intercepting the video short message containing the sensitive words in the sensitive word bank; or replacing the sensitive words contained in the sensitive word library in the video short message by special symbols.

The generated video short messages are filtered according to the set keywords and the sensitive word stock, and the capacity of the video short messages needs to be processed in order to enable the video short messages to be smoothly sent to the terminal.

Optionally, the sending the video short message to be sent to the terminal by the short message platform includes:

According to the method, when the short message platform determines that the capacity of the video short message can be directly sent, the video short message is directly sent to a content distribution server in the CDN; if the short message platform determines that the video short message cannot be directly sent but the capacity of the video short message does not exceed the single information capacity allowed by the CDN, the video short message is encoded and divided into a plurality of video short message data packets and sent to a content distribution server in the CDN; and if the short message platform determines that the capacity of the video short message exceeds the single information capacity allowed by the CDN, the video short message is compressed into the single information capacity allowed by the CDN, the compressed video short message is encoded and divided into a plurality of video short message data packets, and the video short message data packets are sent to a content distribution server in the CDN. Therefore, when the embodiment of the invention is used for sending the large-capacity video short message, the limitation of the message capacity of 300KB can be met, so that the video short message is diversified, and the user experience is improved.

In specific implementation, the short message platform firstly judges whether the capacity of any video short message exceeds a set first threshold value or not aiming at any video short message, and directly sends the video short message to a content distribution server when the capacity of the video short message does not exceed the set first threshold value, and then sends a notification signaling of the video short message;

when the capacity of the video short message exceeds a set first threshold value, the short message platform further judges whether the capacity of the video short message exceeds a set second threshold value, when the capacity of the video short message does not exceed the set second threshold value, the short message platform firstly encodes the video short message, converts the format of the video short message, then segments the video short message after format conversion, ensures that the capacity of each data packet of the segmented video short message after being added with a packet header is still smaller than the set first threshold value, and finally sequentially sends the data packets formed after the video short message is segmented to a content distribution server, and sends a notification signaling of the video short message;

when the capacity of the video short message exceeds a set second threshold, the short message platform firstly compresses the generated video short message, the capacity of the video short message is compressed below the second threshold while the quality of the video short message is ensured, so that the terminal can receive the video short message, then further encodes the video short message, converts the format of the video short message, then segments the video short message after format conversion, ensures that the capacity of each data packet of the segmented video short message after being added with a packet header is still smaller than the set first threshold, and finally sequentially sends the data packets formed after the video short message is segmented to a content distribution server, and sends a notification signaling of the video short message.

Preferably, the set first threshold may be slightly smaller than a maximum value of a size of a short message which can be sent and is specified by an existing short message protocol; the second threshold set may be slightly less than the single piece of information capacity allowed by the CDN.

In a specific implementation, the single information capacity allowed by the CDN is generally 20M for an android user, and 1.9M for an ISO user.

And after the short message platform sends the generated video short message which needs to be sent to the terminal to the content distribution server, the content distribution server carries out subsequent processing.

Optionally, the content delivery server receives the video short message generated and sent by the short message platform and sends the video short message to the CDN edge platform; and sending the platform information of the CDN edge platform determined by the balanced load system according to the position of the terminal to the terminal so that the terminal can obtain the video short message from the corresponding CDN edge platform according to the platform information.

In specific implementation, after receiving data sent by a short message platform, a content distribution server firstly judges that the received data is a complete video short message with an unconverted format and does not process the video short message; if the received data is determined to be the video short message packets with the plurality of converted formats, the plurality of data packets are integrated completely after the packet heads and the packet tails of the data packets are removed to form a complete data file corresponding to the converted format of the video short message, and then the complete data file corresponding to the converted format of the video short message is decoded to obtain the complete video short message.

Meanwhile, the content delivery server determines a CDN edge platform corresponding to the terminal through the balanced load system according to the position information of the terminal determined in the short message notification message, sends the platform information of the CDN edge platform to the terminal, and simultaneously sends an indication message indicating the CDN edge platform as the terminal, a complete video short message and a short message notification message to the CDN edge platform.

Further, after the content distribution server sends the platform information of the CDN edge platform determined by the balanced load system according to the location of the terminal to the terminal, the method further includes:

As can be seen from the above content, after receiving a message of a video short message corresponding to a terminal which is not stored and returned by the CDN edge platform, the content delivery server may have three processing measures.

After receiving a message of a video short message corresponding to a terminal which is not stored and returned by a CDN edge platform, a content delivery server can directly send the video short message corresponding to the terminal to the CDN edge platform which sends the message.

After receiving the message of the video short message corresponding to the terminal which is not stored and returned by the CDN edge platform, the content delivery server inquires all CDN edge platforms storing the video short message through a CDN edge platform list, compares the CDN edge platforms respectively determined according to the target CDN edge platform determined by the position of the terminal through a balanced load system, determines the CDN edge platforms which do not belong to the target CDN edge platform in the CDN edge platforms storing the video short message, and deletes the video short message stored in the CDN edge platforms.

After receiving a message of a video short message corresponding to a terminal which is not stored and returned by the CDN edge platform, the content delivery server can directly send the video short message corresponding to the terminal to the CDN edge platform which sends the message; and querying all CDN edge platforms storing the video short messages through a CDN edge platform list, determining target CDN edge platforms according to the position of the terminal through a balanced load system, comparing the determined CDN edge platforms respectively, determining CDN edge platforms which do not belong to the target CDN edge platforms in the CDN edge platforms storing the video short messages, and deleting the video short messages stored in the CDN edge platforms.

After receiving the message of the video short message corresponding to the terminal which is not stored and returned by the CDN edge platform, the content delivery server can also judge whether a terminal which must send the video short message exists in the terminals which need to send the video short message at present or not after receiving the message of the video short message corresponding to the terminal which is not stored and returned by the CDN edge platform, and then send the video short message corresponding to the terminal to the CDN edge platform which sends the message if the terminal which must send the video short message exists.

And after the content delivery server sends the platform information of the CDN edge platform determined by the balanced load system according to the position of the terminal to the terminal and sends an indication message indicating the CDN edge platform as the terminal, a complete video short message and a short message notification message to the CDN edge platform, the CDN edge platform continues processing.

Optionally, after receiving the video short message sent by the content delivery server, the CDN edge platform sends a download instruction of the video short message to the terminal, where the video short message is a video short message generated by the short message platform and needs to be sent to the terminal; and if the terminal which does not download the video short message exists in the terminals which need to receive the downloading instruction after the set period is reached, sending the downloading instruction of the video short message to the terminal which does not download the video short message.

In the method, after receiving a video short message sent by a content delivery server, a CDN edge platform sends a downloading instruction of the video short message to a terminal, wherein the video short message is generated by a short message platform and needs to be sent to the terminal; and if the terminal which does not download the video short message exists in the terminals which need to receive the downloading instruction after the set period is reached, sending the downloading instruction of the video short message to the terminal which does not download the video short message. Therefore, after the CDN edge platform sends the downloading instruction of the video short message to the terminal, the CDN edge platform can monitor that the terminal which does not download the video short message exists in the terminals which need to receive the downloading instruction, and continues to send the downloading instruction of the video short message to the terminal which does not download the video short message, so that the terminal can finish downloading the video short message only by receiving the downloading instruction once, and further the sending arrival rate of the video short message is improved.

In specific implementation, a CDN edge platform firstly sends a short message notification message sent together with a video short message to a terminal, then directly sends a downloading instruction of the video short message, starts timing, and detects whether all terminals needing to receive the video short message download the video short message or not after a set period is reached; if the terminal needing to receive the video short message does not receive the video short message, sending a downloading instruction of the video short message to the terminal not receiving the video short message; and (5) circulating and reciprocating.

Optionally, after the CDN edge platform sends the download instruction of the video short message to the terminal, the method further includes:

In the method, the CDN edge platform starts a timer, stops sending the downloading instruction after the timer is reached, and reports the result of downloading the video short message by the terminal to the content delivery server. The content distribution server can further take measures according to the result of downloading the video short message by the reporting terminal, and the system performance is improved.

Finally, the terminal receives a downloading instruction of the video short message sent by the CDN edge platform; downloading the video short message from a CDN edge platform; the video short message is generated by a short message platform and is sent by a content delivery server and a CDN edge platform.

The terminal receives a downloading instruction of the video short message sent by the CDN edge platform, successfully downloads the video short message, displays the downloaded video short message and marks that the video short message is successfully sent.

Specifically, the scheme for sending the video short message provided by the embodiment of the invention has various application scenes. A few examples will be given briefly.

1. Emergency command and disaster early warning.

During natural disaster season, a target evacuation area is drawn through an electronic map, a target user group is determined according to user information provided by a base station, then a video short message for generating disaster early warning is sent to the target group of the target evacuation area through a CDN platform, and meanwhile, each terminal user in the target evacuation area can be set to be a necessary target terminal, so that the early warning information of all citizens in the target evacuation area can be accurately and timely sent, emergency evacuation knowledge can be widely publicized, and the consciousness of warning the whole citizens to improve natural disaster risk avoidance and self rescue is achieved.
