Abstract

A portable wireless communication unit (101) is coupled to battery charger/software downloader (108) via a unit interface (304). Upon detecting a flag (402) in the portable wireless communication unit, a software downloader that includes a processing unit (300) connected to a land-based public communication network interface (302) and a memory (306), receives updated software from a server (104) and downloads the updated software to the portable Wireless communication unit via the unit interface.

Claims

1. A method for an integrated battery charger and software downloader to receive updated software from a server, the method comprising steps of:

coupling a portable wireless communication unit to the integrated battery charger and software downloader;

detecting, in the portable wireless communication unit, a flag that indicates availability of the updated software; and

receiving a priority indication from the portable wireless communication unit;

sending to the server, download session parameters to initialize a download session;

receiving, from the server, blocks of the updated software;

storing the blocks of the updated software to produce stored blocks;

updating the download session parameters when the download session has conclude.

2. The method of claim 1, further comprising the step of initiating communication with the server based on the priority indication.

3. The method of claim 2, further comprising initiating communication with the server based on a connection usage profile.

4. The method of claim 3, further comprising initiating communication with the server based on usage costs for a physical connection used by the integrated battery charger and software downloader.

5. The method of claim 1, the step of sending the download session parameters further comprising a step of:

determining the download session parameters based on the priority indication and a connection usage profile.

6. The method of claim 5, the step of sending the download session parameters further comprising sending a block size and a number of blocks remaining to be transferred.

7. The method of claim 1, further comprising a step of sending the stored blocks to the portable wireless communication unit.

8. A method for an integrated battery charger and software downloader to simultaneously charge a battery of a portable wireless communication unit and to download updated software to the portable wireless communication unit, the method comprising the steps of:

coupling the portable wireless communication unit to the integrated battery charger and software downloader;

detecting, by the integrated battery charger and software downloader, a flag, in the portable wireless communication unit, that indicates availability of the updated software;

receiving, by the integrated battery charger and software downloader, a priority indication from the portable wireless communication unit;

initiating, by the integrated battery charger and software downloader, communication with a server via a physical connection to a land-based public communication network;

sending, by the integrated battery charger and software downloader to the server, download session parameters to initialize a download session;

receiving, by the integrated battery charger and software downloader from the server, blocks of the updated software;

storing, by the integrated battery charger and software downloader, the blocks of the updated software to produce stored blocks;

updating, by the integrated battery charger and software downloader, the download session parameters when the download session has concluded; and

sending, by the integrated battery charger and software downloader, the stored blocks to the portable wireless communication unit.

9. The method of claim 8, further comprising initiating communication with the server based on the priority indication.

10. The method of claim 9, further comprising initiating communication with the server based on a connection usage profile.

11. The method of claim 10, further comprising initiating communication with the server based on usage costs for a physical connection used by the integrated battery charger and software downloader.

12. The method of claim 8, the step of sending the download session parameters further comprising a step of:

determining the download session parameters based on the priority indication and a connection usage profile.

13. An integrated battery charger and software downloader for use with a portable wireless communication unit comprising:

a unit interface for providing connections to the portable wireless communication unit;

a software downloader comprising;

a processing unit operably coupled to the unit interface for detecting a flag, in the portable wireless communication unit, that indicates availability of updated software and for downloading the updated software to the portable wireless communication unit when the portable wireless communication unit is coupled to the unit interface;

a land-based public communication network interface operably coupled to the processing unit for communicating with a server to receive the updated software; and

a memory operably coupled to the processing unit for storing the updated software.

14. The integrated battery charger and software downloader of claim 13, further comprising the battery charger operably coupled to the unit interface.

15. The integrated battery charger and software downloader of claim 14 further comprising an activity detector, operably coupled to the land-based public communication network interface and the processing unit, for detecting activity at an input of the land-based public communication network interface.
