Description

A Method of Realizing PIM Data Synchronization Using WPRT Component Layer

technical field

The present invention relates to a method for realizing user personal information management (Personal Information Management, PIM) data synchronization on the WindowsPhone platform, in particular to a method for synchronizing using WindowsPhone runtime components (WindowsPhoneRuntime, WPRT) with SyncML developed based on native C++ (NativeC++) The way the engine interacts.

Background technique

Under the WindowsPhone platform, due to Microsoft’s security considerations, there has always been a certain bottleneck in the synchronization of PIM data under this platform. Before Microsoft announced in October 2012 that the latest WindowsPhone8 version supports NativeC++, the market has not supported PIM data synchronization. The product. SyncML (SynchronizationMarkupLanguage, Synchronization Markup Language) is an open international industry standard data synchronization protocol developed by the International Organization for Standardization OMA (OpenMobileAlliance, Open Mobile Alliance). Using the SyncML data synchronization protocol as a carrier, it is a common practice for PIM data synchronization to convert the PIM data (such as business card holders, calendars, etc.) in the machine into internationally accepted standard formats such as vCard and vCalendar for data synchronization.

So far, there are already some products in mainstream operating systems such as IOS and Android that support native PIM data synchronization on this platform. Restrictions make it impossible to develop an efficient SyncML synchronization engine based on native C++, and are forced to choose to use C# and other managed languages for redevelopment, which seriously affects the operating efficiency of the system and consumes a lot of manpower and material resources.

Contents of the invention

The purpose of the present invention is to solve the problem of user PIM data synchronization on the WindowsPhone platform, abandoning the working idea of re-developing the data synchronization engine and low operating efficiency, and proposing a SyncML synchronization based on the original ecological C++ development using the WPRT component layer The way the engine interacts.

In order to achieve the above-mentioned purpose, the present invention adopts following technical scheme:

A method utilizing WPRT component layer to realize PIM data synchronization, characterized in that:

1) Obtain the device management (Device Management, DM) information stored in the corresponding database of the application, and inject the interface provided by the WPRT layer to the application layer into the synchronization engine of the native C++ layer;

2) According to the information injected by the application layer, the WPRT layer controls the synchronization engine to generate an initial SyncML message containing local configuration information, and feeds back to the application layer for sending;

3) The application layer injects the received server capability message into the synchronization engine through the interface provided by the WPRT layer, and the WPRT layer controls the synchronization engine to analyze for subsequent work;

4) In the application layer, the analyzed and filtered synchronization items (such as business cards, calendars) data in the machine are injected into the synchronization engine through the interface provided by the WPRT layer, and the synchronization engine is started by the WPRT layer to generate the local data message and send Feedback to the application layer until all data packets are generated;

5) The application layer cyclically calls the WPRT layer interface to obtain and send the generated local data packets. Until it detects that all local data messages have been generated, the WPRT layer controls the synchronization engine to add the </Final> tag to the message and send it;

6) The application layer injects the confirmation message fed back by the server into the synchronization engine through the interface provided by the WPRT layer, and the WPRT layer controls the synchronization engine to analyze and generate a request server data message, and then feeds back to the application layer for sending;

7) The application layer cyclically receives the data packets returned by the server, and injects them into the synchronization engine through the interface provided by the WPRT layer for analysis and processing. As long as the synchronization engine does not detect the </Final> mark, the WPRT layer will continue to notify the application layer to receive server datagram;

8) The application layer calls the interface provided by the WPRT layer to obtain the set of server data items processed by the synchronization engine, and stores them in the corresponding database of the machine after processing at the application layer, and updates the data of the machine through a certain screening strategy;

9) After receiving the server data message, the application layer calls the interface provided by the WPRT layer to generate a synchronization completion confirmation message and feed it back to the server;

10) The application layer calls the interface provided by the WPRT layer to inject the synchronization completion message returned by the server into the synchronization engine to complete the whole process of data synchronization.

Compared with the prior art, the present invention has the following innovations:

1. The WPRT component layer is used to interact with the SyncML synchronization engine developed based on the original ecological C++, which effectively utilizes the work efficiency of the SyncML synchronization engine developed based on the original ecological C++ and saves precious mobile phone system resources;

2. By using the WPRT component layer to encapsulate the SyncML synchronization engine developed based on native C++, it can provide SyncML synchronization support for any application developed on the WindowsPhone8 platform in the form of an independent static library or dynamic link library.
