Method for indicating availability of updated software to portable wireless communication units
First Claim
1. In a portable wireless communication unit comprising a wireless transceiver, a processing unit operably coupled to the wireless transceiver, and a memory operably coupled to the processing unit, a method for the portable wireless communication unit to receive indication of availability of updated software, the method comprising steps of:
- receiving a software update query via the wireless transceiver;
transmitting a software update response via the wireless transceiver upon receiving the software update query;
receiving a software update acknowledgment, but not the updated software, via the wireless transceiver; and
setting a flag by the processing unit in the memory responsive to the software update acknowledgment, wherein the flag indicates the availability of the updated software and is used to initiate downloading of the updated software at a later time.

Abstract
In a wireless communication system (100), updated software is downloaded to a server (104). In response to a software update query sent by the server, a portable wireless communication unit (101) sends a software update response back to the server. The software update response can include a priority indication and a usage indication. A software update acknowledgment, sent to the portable wireless communication unit by the server in response to the software update response, causes the portable wireless communication unit to internally set a flag indicating the availability of the updated software. Once aware of the availability of the updated software, the portable wireless communication unit can download the updated software using a combined battery charger/software downloader (108).
