Embodiment Construction

[0043] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The detailed description, which will be given below with reference to the accompanying drawings, is intended to explain exemplary embodiments of the present invention, rather than to show the only embodiments that can be implemented according to the present invention. The following detailed description includes specific details in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. For example, the following descriptions are made with the IEEE 802.16 system as the current access network and the 802 series system or the 3GPP / 3GPPS system as the target access network. However, according to the same principle, the pre-authentication method and the handover method using the pre-authentication method can ...

Abstract

A method for handover between heterogeneous radio access networks is disclosed. When a multi-mode mobile station performs Inter-RAT handover, pre-authentication is performed before implementing a link layer handover procedure with a target access point. The pre- authentication method has as little an effect on currently served quality of service as possible and the handover is efficiently performed using the pre-authentication method. The pre-authentication is performed through medium independent handover (MIH) and various MIH primitives for pre-authentication are provided.

Description

technical field [0001] The present invention relates to a method for handover between heterogeneous radio access networks, and more particularly, to a method for performing handover between heterogeneous radio access networks using a pre-authentication procedure. Background technique [0002] When the communication mobile station moves from one radio access network to another radio access network so that the access point changes, the continuity of service may be broken due to the handover operation. The change of the access point refers to the change of the management domain or the change of the subnet. In particular, handover between heterogeneous radio access networks requires a new authentication procedure. The delay generated due to the execution of the authentication procedure delays the end of the handover procedure and, as a result, affects the currently serving multimedia session. [0003] Meanwhile, in the Institute of Electrical and Electronics Engineers (IEEE) 8...
