This invention relates to a middleware bridge system, for bridging a kernel space module and a user space middleware having a user space interface, including: a kernel space bridge manager, for providing a kernel space interface to receive function call request from the kernel space module; an user space bridge manager, for bringing a function call relating to the function call request to the user space middleware through the user space interface, and receiving a return data from the user space middleware; wherein the architecture of the kernel space interface is the same with the architecture of the user space interface. The present invention further includes a middleware bridge method thereof.
