Description

Shared mobile terminal file offline downloading system, method, storage medium and equipment

Technical Field

The invention belongs to the technical field of off-line downloading of shared files, and particularly relates to a system, a method, a storage medium and equipment for off-line downloading of a shared mobile terminal file.

Background

At present, the downloading technology of a server end mainly comprises the steps of remotely transmitting a file from a main server through a downloading host, and storing the file in an internal memory of the downloading host; the method also comprises an external reading technology of the USB device. Small technical backgrounds include version control technology, network disk synchronization technology, personalized customization technology, and storage sharing technology. There are two main types of existing solutions. One is that the user uses an entertainment client APP, such as the love art, the watermelon video and the like, to download multimedia resources into the APP in an off-line manner, and the user watches off-line cache contents by clicking the APP when the user is off-line with the network; another solution is to use wireless network access methods provided in the scenario, such as WiFi service provided by airliners in passenger aircraft cabins, 5G/4G cellular network service for high-speed rail access. In the prior art, most of the files such as video and audio are downloaded to the intelligent mobile device by the user (offline cache), but the prior art has the disadvantages that the user cannot conveniently acquire the files and entertainment media meeting the requirements, and the prior art consumes network traffic, has unstable bandwidth and too many limited conditions, such as unstable user journey, unstable network connection, insufficient time, insufficient storage space of the user mobile device or occupies the storage space of the user mobile device, thereby causing a series of problems. The user cannot conveniently acquire files and entertainment media meeting the requirements, the reasons are as follows: obtaining various entertainment files is time-consuming and labor-consuming, switching among various platforms is needed, content selection is difficult, and the user does not know what the entertainment files are good and needs content recommendation. Network connection is unstable and slow-reason for high-speed rail scenarios: the base stations on the high-speed rail are not completely paved (the paving cost is high, the return is low), the cellular signals are not stable enough, and the speed is reduced when the signals are weak; unstable and slow network connections-cause of airplane scenarios: at present, the high-altitude internet access mainly adopts two modes, namely satellite communication and ATG ground-to-air broadband communication. The satellite communication bandwidth is narrow, and the internet access application of the light data such as mail receiving and sending, web browsing and the like can be only carried out. The ATG ground-air broadband communication is connected with a network through a land base station, so that the requirement on the ground base station is higher (connection is unstable due to the high-altitude high-speed flight factor of an airplane), the laying cost is high, the return is low, and the popularization range is smaller at present. Insufficient time-reason: the user needs to plan own travel by himself and reserve sufficient time, which is unrealistic for many people, so that offline cache cannot be timely performed in advance in various emergency situations, and if the user does not arrange the travel, the time reserved for the cache is not enough, downloading cannot be smoothly completed, and the user cannot normally use the travel. Problem of consumed flow-cause: a cellular network is required to be used on a high-speed rail, and the traffic charge can be generated in the journey of hours; WiFi bandwidth is expensive to use on an aircraft; offline caching by the user may require access to the cellular network (depending on whether the environment has free high quality bandwidth — WiFi), which may result in traffic tariffs. Insufficient or occupied storage space on the user's mobile device leads to a series of problems-the reasons: the user needs to cache the file into the mobile device for storage, and the normal use of the system is influenced by the limitation of the storage space and the slowing of the system operation speed. Therefore, a new system for downloading shared mobile files offline is needed.

Through the above analysis, the problems and defects of the prior art are as follows: in the prior art, a user cannot conveniently acquire files and entertainment media meeting requirements, network traffic is consumed, bandwidth is unstable, limited conditions are multiple, such as unstable user travel, unstable network connection, insufficient preparation time, insufficient storage space of user mobile equipment or occupation of the storage space of the mobile equipment, so that a series of problems are caused.

The difficulty in solving the above problems and defects is: the existing network technology can not provide cheap, low-cost and high-speed communication service in a closed isolation environment, such as a train and an airplane. The invention adopts intelligent off-line storage, and can effectively overcome the difficulty in using the multimedia data in the scene. The user can not conveniently acquire files and entertainment media meeting the requirements, namely, the solution is as follows: and selecting a proper platform, and reserving the personalized data of the platform to provide personalized recommendation for the platform. Unstable and slow network connection-solution along high-speed rail: laying more cellular network base stations is a great investment for operators, and the return is expected to be low because the height iron mostly belongs to suburbs along the line. (high cost and low return). Solution for WiFi service (high altitude internet access) of an aircraft: 1. the satellite communication connection is stable, but the problem of narrow bandwidth is not broken through at present; ATG ground-air broadband communication requires erection of base stations along aircraft routes, which is costly. Insufficient time-solution: users need to plan their own journey by themselves and reserve sufficient time, but for many people, the implementation is difficult, and offline caching cannot be performed in advance in time under various emergency situations; problem of consumption of traffic — solution: 1. high-speed rail is not solved; 2. the aircraft must pay for the use of the network; 3. the user accesses the free network by himself without worrying about the consumption of the flow. Insufficient storage space or occupation of mobile device storage space leads to a series of problems-solutions: the user purchases mobile equipment with larger storage space by himself, and the mobile equipment is cleaned in time after the journey is finished so as to avoid influencing the running speed of the mobile equipment and the normal use of the system. The significance of solving the problems and the defects is as follows: long-term traffic travel has become an important part of people's daily life. The invention provides a high-performance data use scheme in an isolated closed environment, which can provide rich high-quality multimedia services such as audio and video, entertainment and the like in such scenes, greatly improve the travel comfort of people and reduce the fatigue. The entertainment and media service with more convenience and higher quality (faster speed, more stable connection, lower delay, more and richer content and less selection difficulty) is provided for the user, and the entertainment selection is increased for the travel journey. Meanwhile, the APP can realize the functions of time length charging, charging information display and charging page skipping, user behavior data collection and analysis, user personalized recommendation, intelligent return reminding, anti-lost reminding, U disk content selection, user information display, identity binding, account number registration, downloading host station position and the number of the remaining available U disks and the like. In the using process, the scheme realized by the invention can ensure the maximum stability and fluency (without the limitation of an external network). Meanwhile, the history record and the user personalized recommendation can bring more satisfactory experience for the user.
