Abstract

The present invention relates methods for patching WWAN (Wireless Wide Area Network) communication devices and corresponding WWAN communication devices, integrated circuit chips and computer-readable media. The WWAN communication device includes a first processor, a second processor and a memory. The first processor is arranged to process patches updating software running on the WWAN communication device. The second processor is arranged to provide a first set of the patches to the first processor. The memory stores a second set of the patches to be processed by the first processor. The second processor is further arranged to send a patch end signal to the first processor, the patch end signal causing the first processor to stop processing of patches provided by the second processor. The first processor is further arranged to process the patches stored in the memory independently of the patch end signal.
