Hierarchical switching control signaling system for heterogeneous network and switching method thereof

Abstract

The invention provides a control signaling system providing grading switching between access networks and a switching method, which comprises a service plane,a control plane and an user plane which form a layered structure and are interconnected. The control plane is used for controlling the switching of user equipment between access networks and the data exchange between the service plane and the user plane, and the switching and data exchanging comprise that a session control entity is used for exchanging service data in the service area and a mobile management entity is used for providing grading switching strategies initiated by the core network. The ownership user server is used for data storage of the system and the authentication certification of the user equipment. By the system and the method of the invention, the switching between various present and future access networks is easily realized, the switching delay is short and besides the system and method can be simply and widely applied to the present access network switching.

Description

A Heterogeneous Network Hierarchical Handover Control Signaling System and Handover Method technical field The present invention relates to the field of heterogeneous network technology, and more specifically, the present invention relates to a heterogeneous network hierarchical switching control signaling system and a switching method thereof. Background technique In the network system of wireless, wired and other networks in the future, various network services based on the core network, such as voice, video and real-time and non-real-time services, will communicate with user intelligent terminals through various heterogeneous wireless access networks. to interact. The ubiquitous and heterogeneous nature of the network causes user equipment to frequently change network ownership and management domains. At the same time, seamlessly providing various high-data-rate services to user equipment has become a basic feature of future mobile communication systems. This means th...
