The embodiment of the invention also provides a kind of client; The device that comprises structure packet shown in Figure 3; After this device that makes up packet made up the SyncML packet, client just can be sent to server or mobile phone terminal carries out data sync with the SyncML packet.
Further introduce in the face of the method for structure packet provided by the invention down, as shown in Figure 4, present embodiment comprises:
Step 401: the relevant information of obtaining order to be encoded;
When client is prepared to carry out data sync, at first obtain the relevant information of order to be encoded.The relevant information of order to be encoded comprises the unified sign of reciever of unified sign in this locality of data to be transmitted (being synchrodata), data to be transmitted and data to be transmitted etc.Client is at first obtained the unified sign in this locality of data to be transmitted, and obtains corresponding data to be transmitted according to the unified sign in this locality;
Step 402: the residue space encoder that obtains buffering area;
The space size of buffering area is deducted coded command occupation space, just obtain the residue space encoder of buffering area;
Step 403: calculate the space encoder that order to be encoded needs;
When calculating the needed space encoder of order to be encoded; Because in the SyncML agreement, a synch command has a lot of information sources, and the number of information source also is uncertain; But have only local unified sign (being called for short Source), the unified sign of reciever (being called for short Target) and the needed space encoder of synchrodata (being called for short Data) to change greatly in the synch command; Whether sufficient therefore the space encoder demand relative fixed of other information, and needed space encoder is also little only need consider this three factors when in the calculation code space; So both simplify the calculating of space encoder, and can effectively utilize the space of SyncML packet again.The formula that calculates the space encoder that order to be encoded needs is: space encoder=data to be transmitted length that the order to be encoded needs+this locality unified sign length+unified sign of reciever length+preset coding reservation surplus;
Step 404: judge the space encoder whether above-mentioned residue space encoder needs less than order to be encoded, if turn to step 407, otherwise turn to step 405;
Step 405: this order to be encoded is encoded;
Step 406: the order behind the buffer stores coding, and the residue space encoder of renewal buffering area turn to step 401;
Client turns to step 401 after to current command code to be encoded, order to be encoded is handled to next bar.When order to be encoded is handled to next bar, can utilize in the step 406 the residue space encoder of the buffering area that upgrades to obtain the residue space encoder of buffering area;
Step 407: stop this order to be encoded is encoded, make up the SyncML packet.
Client makes up the SyncML packet according to the coded command in the buffering area, and the SyncML packet that builds is sent to server carries out data sync.
The method of the structure packet of present embodiment; Client is at first obtained the residue space encoder of buffering area, and calculates the space encoder that order to be encoded needs, and comes the dynamic construction synchronization packets according to the space encoder that remains space encoder and order needs to be encoded; Present embodiment can dynamically be adjusted the order number that is structured in the SyncML packet; Can effectively utilize SyncML packet space, reduce the number of times that client makes up and sends packet as far as possible, improve data synchronization efficiency.Present embodiment can also be unified delivery plan to different data types, improves the versatility of SyncML data sync.
