High-performance mobile access gateway and method thereof connecting internal and external information networks

The invention discloses a high-performance mobile access gateway connecting internal and external information networks, and a method thereof. The high-performance mobile access gateway comprises a front-end processor, an intermediate library and a rear-end processor, wherein the front-end processor is deployed in the external information network, is directly connected with an external network mobile application, and is connected with the intermediate library by means of an isolation device; and the rear-end processor and the intermediate library are deployed in the intranet information network, the rear-end processor is directly connected with the intermediate library, and the rear-end processor is directly connected with an internal network business application service. The access methodcomprises the steps that: the external network mobile application sends out an HTTP request; the HTTP request is written into the intermediate library by means of the isolation device after mapping proxy by means of the front
