Embodiment
The solution of the present invention promptly only synchronously transmits the record of those data that changed based on this viewpoint since last secondary synchronization.
So the data that are stored on the smart card are arranged according to index field, that is to say the given index value of each data recording.It should be noted that, " index field " also do not mean that data type must be an array, do not mean that also the length of field is fixed, but index number is continuous, and when removing the data that belong to a record, still there is and keeps its index value in (sky) field location.In addition, sign is associated with each index, and whether its expression changes from the field record that belonged to this index after the data syncization last time.If record change, think that the value of this sign is " dirty ".
All modifications to the record on some index causes that all the sign that is associated with this index is set to " dirty ".This is included in and adds new record, deletion record on the index position of field and revise existing record, even only revise partial record.In the example of telephone directory, add a record and be meant the whole business card of interpolation, the deletion record meaning is meant the whole business card of deletion, and amendment record comprises other information of revising under name, interpolation/deletion modification phone call/facsimile number, interpolation/deletion/modification Email, the interpolation/deletion/modification business card.
During data on upgrading external unit, for example the purpose in order to back up only is sent to external unit with following record, and the sign that is associated with the index that writes down in this record is set to " dirty ".Therefore, smart card is automatically searched the record that has changed.This record that has changed and corresponding index value thereof are sent to described external unit together.
After sending the record that has changed, remove each dirty sign, this is meant that it is set to represent that the record that has belonged to this sign associated index does not change since last secondary synchronization.
The external unit that for example is used for backup intelligence card data also has the memory block of organizing according to the index field of record.The field that this field and smart card are comprised is complementary." coupling " meaning is that an index of field is corresponding on each index and the smart card of field on the external unit.
When external unit received the record that changed and corresponding index thereof, it was with each received recording storage externally on the specified position of the index by receiving with the record that has changed in the device field (DFLD).That is to say, can with the corresponding index of following index under recorded and stored externally on the equipment in the field, in the field of recording storage on smart card under promptly above-mentioned this index.
As mentioned above, the data on the external unit also can be changed by the user.In order to make data that are stored on the smart card and the data synchronised that is stored on the external unit, the then essential data of upgrading on the smart card.Can use the as above same mechanism of institute's summary:
Sign is relevant with each index of record field on the external unit.When externally the record on the equipment has changed, be set to " dirty " with the relevant sign of index under this record.When the user triggers this synchronization, only those records are sent to smart card, sign relevant with the affiliated index of record in these records is set to " dirty ".Every record transmits with its index.On smart card, with the external unit field in the corresponding index of index of record under, in the field of record, the index of the record in the described outside identification field receives with record with each recorded and stored of being received.Externally on the equipment, after sending out the record that has changed, remove each " dirty " sign.
In a preferred embodiment, the present invention proposes the mechanism of handling following situation, this situation just user had not only been added record but also had externally been added record on the equipment on the smart card.Adopt these mechanism, can not lose the record of up-to-date interpolation.
No matter at smart card still on server, whether the sign relevant with each field index also can show under situation about changing except showing whether corresponding record has changed, write down to be added, to delete or to revise.For example, this sign can be formed by 2, and value 00 meaning is " no change " (emptying, non-dirty), and value 01 meaning is " adding record " (dirty), and it is " deletion record " (dirty) that value 10 is looked like, and being worth 11, to look like be " amendment record " (dirty).
Ident value has reflected up-to-date state.Yet,, can only value be set to " amendment record " so if the state of sign is " no change ".For example, if delete described record under a certain index, then added another record under the same index, the value of the sign relevant with this index is " adding record ".If add a record under the index, then revise same record, the value of this sign remains " adding record ".
After this, in order to upgrade the data on the external unit, that is to say, for the record that will change is sent to external unit from smart card, can adopt following mechanism: externally on the equipment, to each receiving record that will upgrade, inquire about the sign relevant with its index, this index is corresponding to the index value that receives with the record that will upgrade.If the value of this sign is " add record ", external unit moves to empty position in the field on the server with this record, and the ident value relevant with this reposition is set to " adding record ", and stores the record that is received down in situ.If there is not empty position in the field, the record that is added alternatively moves in the extension storage district.In addition, if the value of this sign is " no change ", " amendment record " or " deletion record ", then utilize the record that is received directly to cover this record.
For example, following table has been described the ident value of field on the ident value of field on the smart card before the renewal external unit and external unit, wherein, " N " representative " no change ", " A " representative " interpolation record ", " D " representative " deletion record ", " M " representative " amendment record ":
Index Card External unit
1 A A
2 N A
3 M A
4 D A
5 N N (null record)
6 N N (null record)
7 N N (null record)
8 N N (null record)
Sending to external unit from smart card will become the record that belongs to index 1,3,4 with the record that upgrades external unit, just all dirty records.To receive before data write in the field on the external unit, the current record in the external unit field can rearrange in the following way:
Index Card External unit
1 A N
2 N A
3 M N
4 D A
5 N A (former index 1)
6 N A (former index 3)
7 N N (null record)
8 N N (null record)
Similarly, in order to upgrade the data on the smart card, that is to say, for the record that will change on the external unit is sent to smart card, can adopt following mechanism: before the record that will change is sent to this smart card, external unit is inquired about this smart card, has added which record on the smart card.Receive information from smart card then, this information shows its correlated identities value all index for " adding record ".At this moment, for each indicated index, external unit is carried out following operation:
The relevant sign of index of field on inquiry and the external unit, this index is corresponding with indicated index.If the value of this sign is respectively " adding record " or " amendment record ", the record that will belong to this index moves on to the empty position of field on the external unit, and the sign relevant with the index of this position is set to " adding record " or " amendment record " respectively.The sign relevant with the index of original position is set to " no change ".In addition, if ident value is " deletion record ", then this sign directly is made as " no change ".If ident value is " no change ", sign remains unchanged.
By such method, can guarantee that for all index positions wherein the record on this index position has added on the smart card, correlated identities has it and is the value of " no change " (non-dirty) in the external unit field,, thereby can not send on the smart card writing down accordingly; Can not cover the record of interpolation.
For example, following table has been described the mark value of the field on the smart card before upgrading smart card and the mark value of the field on the external unit, wherein, " N " representative " no change ", " A " representative " interpolation record ", " D " representative " deletion record ", " M " representative " amendment record ":
Index Card External unit
1 A A
2 A D
3 A M
4 A N
5 N N (null record)
6 N N (null record)
7 N N (null record)
8 N N (null record)
External unit inquiry smart card is to show the index that has added all records.The sign that smart card checks is relevant with each index, and send a message to external unit, this message shows that the record that belongs to index 1 to 4 adds.Before recording smart card from external unit transmission " dirty ", the field on the external unit can rearrange according to the mode as following table, so that the record that adds on the smart card can not be capped.
Index Card External unit
1 A N
2 A N
3 A N
4 A N
5 N A (former index 1)
6 N M (former index 3)
