Method and apparatus for broadcasting software update information to mobile phones over a wireless communications network
First Claim
1. In a wireless communications network including a multipoint control unit, a base station and a plurality of mobile communications devices associated with the base station, at least one of the plurality of mobile communication devices being in a call mode, a method of replacing a current software file in the plural mobile communications devices with a new software file comprising the steps of:
- the multipoint control unit placing a broadcast download opcode, file version information and file size information into an alert time slot in a frame;
the multipoint control unit placing broadcast download payload information into an idle time slot in the frame and transmitting the frame to the base station;
the base station receiving the frame from the multipoint control unit and broadcasting the frame to all of the plural mobile communications devices associated with the base station;
the at least one of the plurality of mobile communications devices being in the call mode receiving the frame broadcast by the base station, detecting the download opcode, storing the file size information and comparing the file version information contained in the alert time slot of the frame with a current file version information stored in a first memory of the mobile communications device; and
the mobile communications device storing the broadcast download payload information contained in the idle time slot of the frame in a second memory of the mobile communications device at a location specified by the broadcast download payload information if the file version information contained in the alert time slot of the frame and the current file version information stored in the first memory of the mobile communications device are not the same.

Abstract
A local area wireless communications network includes an MCU which generally operates to manage the placement of audio and other information into frames that are transmitted to a base station which serves to convert the frames from one signal format to another signal format and broadcast the frames over a wireless medium to associated mobile communications devices. The wireless communications system operates in a way that permits the broadcasting of new software files from the base stations to associated mobile communications devices in a parallel manner without having a detrimental affect on the operation of the communications system. The MCU operates to place download alert information and download payload information into the frames in such a format and into certain positions in the frame that this information can be recognized and stored by the mobile phones which use it to update their current software.
