Description

System, method, storage medium and device for offline downloading of shared mobile terminal files

technical field

The invention belongs to the technical field of offline downloading of shared files, and in particular relates to a system, method, storage medium and equipment for offline downloading of shared mobile terminal files.

Background technique

At present, the downloading technology on the server side mainly transmits files remotely from the main server through the downloading host, and stores the files in the internal memory of the downloading host first; it also includes the external reading technology of the USB device. The small technical background includes version control technology, network disk synchronization technology, personalized customization technology, and storage sharing technology. There are mainly two types of existing solutions. One is that users use entertainment client APPs, such as iQiyi, Xigua Video, etc., to download multimedia resources offline in the APP, and users can click on the APP to view offline cached content when they are offline; Wireless network access methods, such as WiFi services provided by airlines in passenger aircraft cabins, and 5G/4G cellular network services accessed along high-speed railways. Most of the existing technical solutions are for users to download files such as video and audio to the smart mobile device (offline cache), but the disadvantage is that users cannot easily obtain files and entertainment media that meet the needs, and the existing technical solutions consume network traffic. The bandwidth is unstable, and there are too many restricted conditions, such as unstable user schedule, unstable network connection, insufficient time, insufficient storage space of the user's mobile device, or a series of problems caused by occupying the storage space of the user's mobile device, etc. Users cannot easily obtain files and entertainment media that meet their needs---reasons: obtaining various entertainment files is time-consuming and laborious, and requires switching between various platforms. . The network connection is unstable and slow --- the reason for the high-speed rail scenario: the base station along the high-speed rail is not fully laid (the laying cost is high and the return is low), the cellular signal is not stable enough, the signal is weak and the speed will decrease at the same time; the network connection is unstable and slow- --The reason for the aircraft scene: At present, there are two main ways to access the Internet at high altitudes, one is satellite communication, and the other is ATG ground-to-air broadband communication. The narrow bandwidth of satellite communication can only be used for data-light Internet applications such as sending and receiving emails and web browsing. ATG ground-to-air broadband communication is connected to the network through base stations on land, so the requirements for ground base stations are higher (the connection is unstable due to high-altitude and high-speed flight factors of aircraft), and the laying cost is high and the return is low. Currently, the scope of popularization is small. Insufficient time---reason: users need to plan their own itinerary and allow enough time. This is unrealistic for many people. It is inevitable that they will encounter various emergencies and cannot perform offline caching in advance in time. If there is no If it is arranged well, there is not enough time left for the cache, and the download cannot be completed smoothly, so it cannot be used normally during the itinerary. The problem of traffic consumption---reason: the high-speed rail needs to use the cellular network, and traffic charges will be incurred during the journey for several hours; the use of WiFi bandwidth on the plane is more expensive; the user may need to access the cellular network for offline caching (depending on whether the environment is There is free high-quality broadband-WiFi), and traffic charges will be incurred. The storage space of the user's mobile device is insufficient or the storage space of the user's mobile device is occupied, causing a series of problems---reason: the user needs to cache files to the built-in storage of the mobile device, which is limited by the storage space and slows down the system's operating speed, affecting the normal use of the system possible. Therefore, there is an urgent need for a new offline download system for shared mobile terminal files.

Through the above analysis, the existing problems and defects of the existing technology are: users of the existing technical solutions cannot easily obtain files and entertainment media that meet the needs, consume network traffic, unstable bandwidth, and many restricted conditions, such as unstable user schedules , the network connection is unstable, the preparation time is insufficient, the storage space of the user's mobile device is insufficient or the storage space of the mobile device is occupied, causing a series of problems, etc.

The difficulty in solving the above problems and defects is that existing network technologies cannot provide cheap, low-cost, and high-speed communication services in closed and isolated environments, such as trains and airplanes. The present invention adopts intelligent off-line storage, which can effectively overcome the difficulty in using multimedia data in such scenarios. Users cannot easily obtain files and entertainment media that meet their needs---solution: choose a suitable platform, and keep their personalized data, so that the platform can provide personalized recommendations. The network connection is unstable and slow---the solution along the high-speed rail line: laying more cellular network base stations will be a very large investment for operators, and since most of the high-speed rail lines are in the suburbs, it is foreseeable The returns are low. (High cost and low return). Solutions for aircraft WiFi service (high-altitude Internet access): 1. The satellite communication connection is relatively stable, but the problem of narrow bandwidth has not yet been broken; 2. ATG ground-air broadband communication needs to set up base stations along the aircraft route, which is costly. Insufficient time---solution: users need to plan their own itinerary and allow enough time, but it is difficult for many people to realize it, and it is inevitable that they will encounter various emergencies and cannot be cached offline in time in advance; The problem of traffic consumption---Solutions: 1. There is no solution for high-speed rail; 2. Airplanes must pay to use the network; 3. Users can access the free network by themselves, so they don’t have to worry about consuming traffic. Insufficient storage space or occupation of mobile device storage space leads to a series of problems---solution: users purchase mobile devices with larger storage space by themselves, and clean them up in time after the trip to avoid affecting the running speed of the device and the normal use of the system. The significance of solving the above problems and defects is that long-time traffic trips have become an important part of people's daily lives. The present invention provides a high-performance data usage scheme in an isolated and airtight environment, which can provide rich and high-quality multimedia services such as audio-visual and entertainment in such a scene, greatly improving people's travel comfort and reducing fatigue. Provide users with entertainment and media services that are more convenient and of higher quality (faster speed, more stable connection, lower latency, more and richer content, and less difficult choices), and increase entertainment choices for travel itineraries. At the same time, the APP can realize the functions of time billing, charging information display and jumping to the charging page, user behavior data collection and analysis, user personalized recommendation, intelligent return reminder, anti-lost reminder, selection of U disk content, display user information, identity binding , account registration, check the location of the download host site and the number of remaining available USB drives, etc. During use, the solution realized by the present invention can guarantee maximum stability and fluency (not restricted by external network). At the same time, historical records and user personalized recommendations can bring users a more satisfactory experience.
