Description

Modification information management method and terminal

technical field

The present invention relates to the communication field, in particular, to a management method and a terminal for modifying information.

Background technique

The management of mobile phone personal information, schedule information and mail information is becoming more and more important, and has become an important part of mobile phone information management. The data can be backed up to the network server and computer. When the mobile phone is replaced or the data of the mobile phone changes, the backup data can be easily restored to the mobile phone; data can also be transmitted between mobile phones. The SyncML protocol can realize the connection between the mobile terminal and the network server. , PC, and mobile phone data synchronization.

In the current SyncML protocol, in order to reduce the data traffic during synchronization, a fast synchronization synchronization method is specified in the protocol, so that only the data changed after the last synchronization needs to be synchronized during synchronization. To achieve this purpose, the terminal and the server need to record the modification information (changelog) of their own data after the last synchronization. If you need to synchronize with multiple servers, at the same time, after synchronizing with one server, if the data on the terminal is modified during this synchronization, the modification information needs to be added to the modification information record of each server at the same time. Note: The multiple servers mentioned here are independent of each other, no synchronization information will be exchanged, and the terminal interacts with different servers separately.

A method is provided in the related art. The method is to establish a modification information (changelog) file corresponding to each server that needs to be synchronized on the terminal. Each changelog file is independent of each other. When the data of the terminal is modified After that, the modification information is added to the modification record corresponding to each server, so that when performing fast synchronization on a certain server, it is only necessary to read the modification information from the changelog information file corresponding to the server, and then synchronize to the corresponding server superior.

Fig. 1 is a schematic diagram of distributed management modification information according to related technologies.

The method of managing multiple changelogs in the related art mainly has two disadvantages: 1. Since each server has its own independent changelog records, many of the same information is in these changelogs in the case of multiple servers, which makes the terminal need More storage space to store these modification records. 2. Since every modification of a piece of data needs to modify all server changelog information on the terminal, this greatly reduces the efficiency and slows down the speed of synchronization.

Aiming at the problem in the related art that terminals often require a large amount of storage space to store modification records, no effective solution has been proposed yet.

Detailed ways

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Through the present invention, it can meet the needs of fast synchronization between a SyncML terminal and different servers.

method embodiment

According to an embodiment of the present invention, a method for managing modification information is provided.

Fig. 2 is a flowchart of a method for managing modification information according to an embodiment of the present invention.

As shown in Figure 2, the method includes the following steps S202 to S204:

Step S202, the terminal acquires modification information, wherein the modification information is modification information corresponding to multiple servers;

Step S204, the terminal records the modification information in the same modification information log file.

The implementation process of the embodiment of the present invention will be described in detail below with reference to examples.

The present invention proposes a method for centralized management of modification records corresponding to multiple servers on a terminal and a data modification process. By adopting the centralized management method, the storage space for storing modification information of multiple servers is greatly reduced, and at the same time, the operation complexity is reduced. degree, improving the efficiency of synchronization.

Optionally, the present invention aims at that when data synchronization may need to be synchronized with multiple servers, after the synchronization with one server is completed, the terminal device can ensure that it can switch to another server to perform fast synchronization without needing to perform fast synchronization after switching servers. A slow sync must be initiated.

Fig. 3 is a schematic diagram of centralized management modification information according to an embodiment of the present invention.

In the present invention, in order to perform fast synchronization with multiple servers, the data change information corresponding to each server can be recorded on the terminal. Information can also be managed separately. When the local data changes, it is necessary to change the data change records corresponding to all servers. In practice, there are two situations:

1. Changes to terminal data generated when synchronizing with a server;

2. Data modification generated by local operation on the terminal.

For the first case, if the server modifies the data of the terminal during the synchronization process, after the terminal successfully modifies the local data, it needs to modify the modification information (changelog) of other servers except the current synchronization. For the current synchronization server, You need to clear the changelog information of this piece of data.

A preferred management method for modifying information according to an embodiment of the present invention may include the following steps:

Step S1, the terminal receives and parses the command sent by the server, wherein the command is used to instruct to modify the data of the terminal;

Step S2, the terminal modifies the local database according to the command.

Preferably, the terminal can handle the following situations according to different server commands:

Situation 1: If the server sends a command to add a data item, add the data information in the changelog information, and set the other server operations corresponding to the data as adding operations, and delete the data related to the synchronizing server Change information.

Situation 2: If the server sends a command to modify the terminal data, find the information corresponding to the data in the changelog information, and modify the other server operation information corresponding to the data accordingly. If the original recorded change information is an increase or modification operation, the record remains unchanged. If the original record is a deletion operation, the change information is changed to a modification operation. At the same time, delete the change information about the piece of data with the server being synchronized.

Situation 3: If the server sends a command to delete terminal data, find the information corresponding to the piece of data in the changelog information, and modify the other server operation information corresponding to the piece of data accordingly. If the original recorded change information is added operation, delete the change information, and if the original record is an update or delete operation, change the change information to a delete operation. At the same time, delete the change information about the piece of data with the server being synchronized.

For the second case, since the modification operation occurs locally on the terminal, its operation has not been communicated to any server that needs to be synchronized, so the modified change information needs to be added to the modification information of all servers, and its specific operation is the same as that of the first type The situation is the same.

In the case of distributed management of changelog information, since the changelog files corresponding to each server are independent of each other, it is necessary to search for the changelog file when changing the change information of a piece of information, assuming that the number of servers to be synchronized is m , if there are n pieces of data on the terminal, the time complexity of modifying the changelog information after modifying one piece of data locally is O(n*m). They are interrelated and stored together. Therefore, the time complexity of modifying the changelog information after modifying a piece of data locally is O(n+m). It can be seen that the centralized management of changelog information of multiple servers is much better than the distributed management method in terms of operational efficiency.

From the above description, it can be seen that the present invention achieves the following technical effects: through centralized management of changelog information of multiple servers, the storage space for storing these information is reduced, the operation complexity is reduced, and the synchronization efficiency is improved.
