Abstract
The method of conveying control and program information between cellular radiotelephone controllers and of detecting information errors is disclosed. When a program memory information error is detected, a predetermined amount of memory information is conveyed from a first controller to a second controller. If a comparison of checksums of a predetermined amount of memory information stored at the second controller and the memory information received from the first controller matches, additional memory information is conveyed. If a match is not found, the predetermined amount of memory information is reconveyed from the first controller to the second controller.
