Problems solved by technology

[0011] It defines the name, mobile phone and email address of the contact. This kind of vCard text can only define a single contact, and cannot define a contact group, that is, it cannot store the information of the group to which the contact belongs.
Due to this limitation, even though many terminal devices and servers can define groups, when these devices synchronize contact information through vCard, these group information will be lost during synchronization or transmission

Embodiment Construction

[0032] The present invention realizes the bearing of group information in data synchronization by extending the existing vCard protocol, thereby completing the group information synchronization function.

[0033] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0034] As shown in Figure 2, it is a schematic diagram of the device structure used to transmit vCard data, where both device a and device b include the following four modules: database module 3, application layer module 4, transport layer module 5, and electronic business card codec 6 . The database module 3 stores the user's contact information and contact group information. The application layer module 4 mainly completes applications based on the address book or address book, such as address book backup, short message receiving and sending box, MMS receiving and sending box, and email receiving and sending box. The role of the ...

Abstract

The invention relates to a method for making data synchronous between devices, wherein when the first device receives the data synchronous command, distributing the electric card coder/decoder in first device; the coder/decoder reads the recode in database which comprises communicator information and group information, to build the electric card context with group information; the first device transmits the electric card context to the second device; the second device distributes itself coder/decoder to decode the electric card context, to get out the communicator information and group information, and build up the record with said communicator information and group information, to be stored in itself database. The invention utilizes the expand mechanism of electric card, adds group information, while devices communicate electric card, it can keep group information, to support group management on communicator information.

Description

Technical field [0001] The present invention relates to a method for data synchronization between devices, in particular to a method for transferring contact data containing group information between various terminals or between a terminal and a server. Background technique [0002] With the development and popularization of mobile communication technology, mobile communication has become one of the most important means of communication and communication for people. In mobile communication, the importance of mobile terminals to mobile users is self-evident, for the convenience of mobile users In the mobile terminal, there are usually a large number of contact information of relatives, friends and customers. These contact information of relatives, friends and customers are usually very important. If the contact information is lost, it will not only be difficult to restore it, but also It may cause great inconvenience to daily life and business activities. [0003] In order to prev...
