The embodiment of the invention relates to the technical field of communication, in particular to a hot patching method and equipment, which is used for reducing the probability of system interrupt and system fault caused in hot patching when the distance between a patching function and a patching function is too long. In the embodiment, a jumping function information table is obtained, at least one jumping function at unused state is determined from the jumping function information table, and a jumping channel is produced; a first short jumping function is added in front of the patched function, wherein the first short jumping function is used for a first jumping function jumping from the patched function to the jumping channel and further jumping from the jumping channel to the patching function, so that the problems of program interruption and system fault when the patched function is repositioned to the patching function through long jumping in the prior art are avoided.
