Abstract

A method of managing data transfer from a server to an electronic device via a wireless communication, includes initiating a synchronization of a database of the electronic device with the server and determining, by the electronic device, a length of time since the synchronization of the database of the electronic device with the server. The method also includes, in response to determining that the length of time meets the threshold period, determining a quantity of data records for sending from the server to the electronic device to perform a further synchronization and requesting one of complete data records or incomplete data records based on the quantity of data records for transfer to the electronic device.

Claims

1. A method of managing data transfer from a server to an electronic device via a wireless communication, the method comprising:

initiating a synchronization of a database of the electronic device with the server;

determining, by the electronic device, a length of time since the synchronization of the database of the electronic device with the server;

in response to determining that the length of time meets the threshold period of time;

determining a quantity of data records for sending from the server to the electronic device to perform a further synchronization;

requesting one of complete data records or incomplete data records based on the quantity of data records for transfer to the electronic device.

2. The method according to claim 1, wherein determining, by the electronic device, a length of time is performed in response to re-establishing wireless communications after disconnecting the wireless communications.

3. The method according to claim 1, wherein requesting one of complete data records or incomplete data records comprises, in response to determining that the quantity of data records exceeds a threshold number, requesting, by the electronic device, incomplete data records from the server, wherein the incomplete data records include less than all fields of the data records for transfer to the electronic device.

4. The method according to claim 3, wherein requesting one of complete data records or incomplete data records comprises, in response to determining that the quantity of data records is less than the threshold number, requesting, by the electronic device, complete data records from the server, wherein the complete data records include all fields of the data records for transfer to the electronic device.

5. The method according to claim 3, wherein the threshold number is based on a quality of a wireless communication connection.

6. The method according to claim 3, wherein requesting, by the electronic device, the incomplete data records comprises requesting headers of the data records.

7. The method according to claim 3, comprising receiving the incomplete data records at the electronic device.

8. The method according to claim 7, wherein receiving the incomplete data records comprises receiving headers of the incomplete data records and not receiving bodies of the incomplete data records.

9. The method according to claim 8, wherein the incomplete data records are absent any data record attachments.

10. The method according to claim 7, comprising, after receipt of the incomplete data records, requesting remaining fields of the data records to complete the data records and receiving the remaining fields of the data records.

11. The method according to claim 10, comprising, in addition to receiving the remaining fields of the data records, receiving data record attachments to complete the data records.

12. A non-transitory computer-readable medium having computer-readable code stored thereon, the computer-readable code executable by at least one processor of a portable electronic device to perform the method according to claim 1.

13. An electronic device comprising:

a memory for data storage;

a display for displaying information thereon;

an input device; and

a communications subsystem for receiving data at and sending data from the electronic device; and

a processor operably coupled to the memory, the display, the input device; and

the communications subsystem, and configured to;

initiate a synchronization of a database stored in memory of the electronic device;

determine, by the electronic device, a length of time since the synchronization of the database of the electronic device with the server;

in response to determining that the length of time meets the threshold period of time;

determine a quantity of data records for sending from the server to the electronic device to perform a further synchronization; and

request one of complete data records or incomplete data records based on the quantity of data records for transfer to the electronic device.

14. The electronic device according to claim 13, wherein the length of time is determined in response to re-establishing wireless communications after the wireless communications are disconnected.

15. The electronic device according to claim 13, incomplete data records are requested in response to determining that the quantity of data records exceeds a threshold number, and wherein the incomplete data records include less than all fields of the data records for transfer to the electronic device.

16. The electronic device according to claim 15, wherein complete data records are requested in response to determining that the quantity of data records is less than the threshold number, and wherein the complete data records include all fields of the data records for transfer to the electronic device.

17. The electronic device according to claim 15, wherein the threshold number is based on a quality of a wireless communication connection.

18. The electronic device according to claim 15, wherein the incomplete data records include headers of the data records and no body.

19. The electronic device according to claim 15, wherein the incomplete data records are absent any data record attachments.

20. The electronic device according to claim 15, wherein the processor is configured to request missing fields to complete the incomplete data records after receipt of the incomplete data records.
