How to Manage Handoff Request Calls Using Sorted Queues

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a method for managing a handoff request call using an ordered queue.;2. Technical problem to be solved by the invention;According to the present invention, the cell size is gradually decreased due to the increase in the number of mobile terminal users, and accordingly, the handoff demand increases. Therefore, when a handoff fails, a call requesting a handoff is disconnected during a call, causing user inconvenience. It is intended to provide a method for managing handoff request calls that can be prevented in advance and can manage an increasing number of handoff request calls.;3. Summary of the Solution of the Invention;The present invention calculates an estimated time for the mobile terminal to stay in the handoff region based on information on the speed of the mobile terminal in the handoff region, the distance and angle to the handoff region boundary, that is, the direction of movement of the mobile terminal. By first assigning channels to the smallest mobile terminals, we try to prevent handoff attempts in the queue in the middle and to minimize the user's disadvantage due to unstable wave strength change.;4. Important uses of the invention;The present invention is used to manage handoff request calls.
