Abstract
The invention discloses a method of synchronization initiated by a dynamic content distributing (DCD) service server. A synchronous notification message the synchronous mode of which is a retreating synchronous mode is sent to a terminal through a DCD server; terminals respectively delay different time after judging the retreating synchronous mode; when the delay time is reached, each terminal sends a synchronous request message to the DCD server to carry out synchronization, so under the condition that the DCD server requires large amount of terminals to simultaneously synchronize, each terminal can not send the synchronous request message at the same time, and the terminals are connected with the DCD server, which can not cause overload of the DCD server but can increase the stability ofthe server. Meanwhile, the invention also discloses a system of synchronization initiated by a DCD server.
Description
Technical Field
The present invention relates to communication technology, and is especially dynamic content distributing service server initiated synchronizing method and system.
Background
A Dynamic Content Distribution (DCD) service is a service that aims to improve the information browsing experience of end users. The method updates the content personalized and customized by the user to the terminal of the user in a periodic downloading or pushing mode. The DCD service greatly reduces the difficulty of content discovery and content acquisition, simplifies the operation mode of the user, and enables the user to conveniently and quickly acquire the most needed content. Since the data of the DCD service is updated on the DCD server at regular time, the terminal timing is also required to be synchronized with the DCD server to update the local data.
The terminal initiates synchronization in the following ways:
the terminal actively initiates synchronization:
the method comprises the following steps: the method comprises the steps of initiating synchronization (MC synchronization) when a terminal master clears, initiating synchronization (MR synchronization) when the terminal master resets, initiating synchronization (START synchronization) when a user STARTs up, initiating synchronization (MAN synchronization) when the user manually refreshes, initiating synchronization (TTL synchronization) when synchronization time reaches, and retrying initiated synchronization (RETRY synchronization) after synchronization abnormity.
And if the terminal does not have main clearing and main resetting at the same time and only has factory reset restoration, the user selects factory reset restoration, and the terminal triggers MR synchronization.
The DCD server actively initiates synchronization:
the synchronization triggered by the DCD server (SVR synchronization) means that a user actively initiates by an administrator after changing channels (adding channels, deleting channels or personalized channel change keywords) in various modes, the DCD server automatically sends a synchronization notification message to the terminal, the terminal sends a synchronization request message to the DCD server according to the content of the message after receiving the synchronization notification message, and the DCD server sends a synchronization data packet to the terminal according to the synchronization request message;
the synchronization notification message is a wireless Push message (WAP Push message), and the content of the WAP Push message conforms to the standard Open Mobile Alliance (OMA) specification, and includes the following contents: DCD server address, Application-ID, relative address for content synchronization, etc.
In the rapid development of the DCD service, most of the third generation mobile communication technology (3G) clients are pre-configured with the DCD service, which is as short as 2 years, and the number of DCD users is already tens of millions. In such a large user group background, it often happens that the DCD server triggers the terminal to refresh the content in batch due to platform upgrade, etc., which will lead to the explosion of the DCD server receiving the synchronization request message of the terminal in a short time.
Meanwhile, for the consulting DCD service, the DCD server has the requirement of simultaneously initiating the synchronization of a large number of terminals, and the solution of the contradiction is imperative.
Currently, a method for a DCD server to initiate synchronization of multiple terminals simultaneously is shown in fig. 1, and the method includes the following steps:
step 101: the DCD server simultaneously sends a synchronization notification message to each terminal;
step 102: after receiving the synchronization notification message of the DCD server, each terminal returns a synchronization request message to the DCD server;
step 103: after receiving the synchronization request message, the DCD server sends a synchronization data packet to the terminal;
the synchronous data packet comprises information such as a synchronous channel, a file downloading address and the like;
step 104: the terminal receives and analyzes the synchronous data packet, if the analysis is successful, the step 105 is executed; if the analysis fails, go to step 107;
the synchronous data packet is analyzed through an analysis function, and information such as a synchronous channel, a file download address and the like in the synchronous data packet is analyzed;
step 105: the terminal downloads the file from the DCD server according to the analyzed file downloading address, and if the terminal downloads the file successfully, the step 106 is executed; if the download fails, go to step 107;
step 106: the synchronization is successful, and the process is ended;
step 107: the terminal enters a retry process when the synchronization fails;
according to the method, when the DCD server triggers the terminal to synchronously refresh the content in batch due to platform upgrading and the like, the terminal almost returns the synchronization request message to the DCD server at the same time, so that the synchronization request message of the terminal received by the DCD server in a short time is increased, and because the DCD server is connected with a large number of terminals at the same time, the load of the DCD server is increased greatly, and even the DCD server is overloaded.
