Abstract
A method and device for an inter-RAT handover for a PS service in a dual-mode RNC are disclosed in the present invention, which are used to support an inter-RAT handover optimization flow of the PS service in the dual-mode RNC, thereby solving the problem that the current inter-RAT handover optimization flow does not support the PS handover. With the present invention, in the inter-RAT handover optimization flow, an inter-RAT relocation flow and a radio resource allocation flow of a destination system are executed in parallel, and an encryption indication is sent to a central network through inter-RAT relocation required message; a BSC forwards user data to the central network according to the encryption indication.
