A new spotbeam handover management technique for LEO satellite networks

AbstmctThe geographical connection admission control (GCAC) algorithm is introduced for low earth orbit LEO) satellite networks. The GCAC scheme estimates the L u r e handover blocking probability of a new call attempt based on the user location database, in order to decrease the handover blocking. By simulation, it is shown that the proposed GCAC scheme guarantees the handover blocking probability to a predeflned tar et level. Since GCAC algorithm utilises the user location information, performance evaluation shows that this technique also guarantees the target level of handover blocking probability in the nonuniform t r d c pattern.
