Title: Cell handover in a multimedia cellular communications system; multimedia conferencing system
Inventor: WHINNETT NICHOLAS WILLIAM
IPC: H04M3/56
Filed: 1996-05-17
Abstract: Cell handover in a cellular multimedia conferencing system is effected using a cell selection processor 325 in a mobile and/or in the fixed infrastructure (523, Fig.7). A quality processor 401 determines an overall quality measure for each handover candidate cell based on signal quality measurements for each medium, mode capability, and resource availability for that cell, and on media requirements and relative priorities for the current call. The processor 401 also determines an overall quality measure for the current cell. The handover candidate cells are then ranked 417 in a prioritized list. A triggering control 423 receives the overall quality information relating both to the current cell and to a preferred candidate cell from the list and indicates to a schedule controller 427 that one or more media should be handed over. The controller 427 uses the data from control 423, together with resource availability data 419 relating to the handover candidate cell and activity status multimedia mode information 425 to determine the times that one or more media will be handed over to one or more candidate cells. Controller 427 also determines media to be suspended, or if any previously suspended media are reactivated in the new cell. If a medium is not capable of being transferred at handover, its data can be stored and then forwarded to the candidate cell at a later time or when handed off to a new candidate cell.
