A method of loading software in cellular telecommunication systems is disclosed. The method permits software data to be loaded in the background while transceiver devices may be engaged in voice or data traffic. Each of the devices includes a run-time memory, backup memory, and a device processor. The data is transmitted from the mobile switching center to the backup memory of the designated device while the device is operating from run-time memory. In a first embodiment, the data is copied from backup memory to run-time memory when the device is idle. In a second embodiment, device operations are switched to run from backup memory when the device is idle. Subsequent software loadings cycle between run-time and backup memories. In a third embodiment, a single memory bank comprises both run-time and backup memory. The backup memory area is located in a different location in the memory bank than the run-time memory area. The software data is written in the background to the backup memory area without disturbing device traffic. When the device is idle, the location pointer is switched to the backup memory area so that the device runs newly loaded software. The inventive concept permits efficient software loading that reduces down-time and is transparent to the user.
