A method for quick switching of mobile terminal

The utility model relates to a method for mobile terminal to perform fast handoff, which comprises: A. A target access gateway transfers handoff request message to a source access gateway; B. The source access gateway responds with the request and transfers context information of the mobile terminal to the target access gateway; C. The target access gateway assembles the context and feedbacks theresult of context assembling to the source access gateway; D. The source access gateway / the target access gateway determine whether to process grouped data according to the result of the target access gateway context assembling. The utility model has advantages that the target access gateway sends the information of whether the result of context assembling having been successful to the source access gateway after the source access gateway sending context information to the target access gateway, making the source access gateway process the grouped data continuously when the context assembling of the target access gateway fails, avoiding the grouped data loss after assembling failure.
