Beschreibung
Zusammenfassung:	In GSM EDGE radio access network (GERAN), the assignment of cells to packet control units within a base station-controller is of key importance to optimize the quality of service experienced by end users. In this paper, a novel methodology is presented to optimize this assignment by means of graph partitioning theory. The proposed algorithm aims at minimising the number of cell re-selections between cells on different packet control units based on handover information. Results from the application of the method in a live network show its capability to improve end-user performance in terms of service delay and application throughput.
