Refer again to Fig. 3 and describe data-updating method according to the embodiment of the invention, this method may further comprise the steps:
Mobile device M has upgraded up-to-date content synchronously on the metadata cache server A;
Mobile device M sends " moving an indication " message and gives the metadata cache server A then, and this message comprises the destination B of next jumping of mobile device M and the time t of arrival;
The metadata cache server A is received after " moving indication " message, know that the metadata cache server corresponding to next jumping of mobile device M is B, so send " upgrading indication " message to the metadata cache server B, comprise the sign of mobile device M and the t time of advent of mobile device M in this message;
The metadata cache server B is according to the update time of content server (data source) and the t time of advent of mobile device M selecting a best time to carry out the more newly downloaded of content;
Mobile device M is moving, and will arrive the metadata cache server B in moment t;
Mobile device M arrives after the metadata cache server B, and mobile device M downloads up-to-date update content from the metadata cache server B, finishes the synchronous renewal of content;
Mobile device M sends " moving an indication " message and gives the metadata cache server B then, this message comprise next jumping of mobile device M destination C and the time of advent tt.Follow-up operating procedure repeats above process.
Describe below according to another embodiment of the present invention.
New applied environment such as bullet train to on-vehicle information service have higher requirement, except entertainment forms such as traditional in-car TV, broadcasting, the passenger has more produced demand to the information service of personalization.Along with further popularizing of the terminal equipment of configuration such as notebook WiFi, making up broadband wireless environment such as WiFi in train has become a trend for the user provides personalized information and entertainment service, and also part has been carried out experiment.
In order to overcome drawbacks such as adopting wide area wireless network link instability, speed in bullet train is used are low, expense costliness, also there is the part experimental system to propose to be the mode of the vehicle-mounted caching server of train configuration, by the part web page contents is buffered on the vehicle-mounted caching server, the user is the content of the vehicle-mounted caching server of high speed access the inside (webpage, video, and music etc.) directly, thereby improves the user experience that the passenger visits these information contents.
Shift to an earlier date the cache web pages content by setting up server on the platform AT STATION, and utilize the train intermittence to carry out content synchronization fast by the time at big station, train-installed content caching server and platform content caching server, this method possesses the characteristics that cost is low, efficient is high, and very strong manageability is arranged.This embodiment is that a kind of being applicable to upgraded the data-updating method of platform cache contents under this application scenarios efficiently.
Content on the metadata cache server on the platform is from the data source of outside, and this data source can be the website of website, particular news or content supplier on the Internet etc.Metadata cache server on the platform is downloaded the up-to-date content of these external data sources as much as possible, offers vehicle-mounted caching server then.
Carry out update content between the metadata cache server on train-installed caching server (mobile device M) and the platform relatively, then with the content delivery of " renewal " on the metadata cache server on the platform to vehicle-mounted caching server, thereby make that the cache contents on vehicle-mounted is new as much as possible.Train is intermittent by the station, and its time by specific station is basic fixed.In this embodiment, utilize this characteristics, by a series of flow processs, allow the platform metadata cache server at corresponding station before train arrives, from external data source, download up-to-date data content as far as possible accurately, thereby make when train arrives this platform, can download up-to-date content from this platform metadata cache server.
Committed step in the above process comprises: upgrade current up-to-date service content on the metadata cache server of train from the current platform synchronously, comprise webpage, video, audio frequency etc.; Train is notified the server of the metadata cache on the current platform with where oneself when arriving the information at station, and the metadata cache server is with the sign of this train with notify its time of advent this train to be about to the platform metadata cache server at the station, following station that arrives certainly; The platform metadata cache server of the next stop goes data source to download up-to-date data content according to train the time of advent, guarantees that as far as possible this content is up-to-date before train arrives; When train arrives " next stop ", the renewal of the content of the metadata cache server on the platform of " next stop " is finished, thereby train-installed caching server just can be finished the renewal of vehicle-mounted caching server content directly from the up-to-date content-data of metadata cache server acquisition of platform.Train passenger just can have been visited on the vehicle-mounted caching server what be new.
In the present invention, by (for example at some specific application scenarioss, content synchronization between train-installed caching server and the platform metadata cache server) in, use following steps: when mobile device M and current metadata cache server content upgrade synchronously finish after, it will oneself next jumping will be synchronous information such as server, the time of advent clearly circulate a notice of to current data in synchronization caching server; The content that current metadata cache server has upgraded this mobile device and when can connect Next Hop Server and carry out the server that synchronous information notifies next jumping to connect in the mode of " upgrading indication "; Next Hop Server receives that current server " upgrades indication " afterwards, will finish up-to-date Data Update before mobile device M arrives.That is, be the characteristics that can expect by the mobility that makes full use of mobile device, can improve updating efficiency greatly.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
