Method and network controller for reducing traffic load of multiple carriers to trigger carrier switch-off in wide area mobile networks

摘要

Method for reducing traffic load of multiple N carriers, comprising measuring the CS and PS traffic load both in downlink and uplink, evaluating the suitability of carrying the measured traffic load values in N-1 carriers and reconfiguring the traffic load from one of the N carriers towards the other N-1 carriers. For evaluation of the suitability of carrying the traffic load in N-1 carriers, the traffic with a SPI is associated with a label indicating a degree of vulnerability of said traffic to its transmission in case that at least one of the N carriers is switched off. An alternative scheduling priority indicator (SPI') is assigned to said traffic in accordance to its SPI and label. The alternative scheduling priority indicator (SPI') can be used by a RNC for triggering a HSPA scheduler in a Node B to schedule the traffic.
