Mobile communications system, radio network controller, and active set control method |
摘要 |
An active set control method for handover operation in a CDMA communications system in which propagation conditions of an uplink channel and a downlink channel for an access link of cell are different, provides that when a cell is deleted from the active set based on a request of a base station which has detected a degraded signal of the uplink channel, a predetermined period of time is to be counted for inhibiting addition of the same cell in the active set based on a request of a mobile terminal which has detected a satisfied signal of the downlink channel, thereby preventing the deletion and addition of the cell in the active set from successive operations in a short time.
