<p>Embodiments of the present invention provide a method, a device and a system for communication between double central processing units, which relates to the field of mobile communications technologies. An embodiment of the present invention provides a method for communication between double central processing units, where the method includes: receiving, by a baseband function module, a baseband function invocation request message sent by an application function module through a service channel and a virtual channel, where the baseband function invocation request message carries a virtual channel identifier, and the virtual channel identifier corresponds to the virtual channel; and in response to the baseband function invocation request message, returning, by the baseband function module, a baseband function invocation response message to the application function module, where the baseband function invocation response message carries the virtual channel identifier. Through the embodiments of the present invention, conflicts in a process of communication between double CPUs can be avoided, and the communication implementation process and application process are also simplified.</p> |
