Inter-radio access technology transition based on quality of service evaluation

摘要

A method for determining whether to allow performance of an inter-radio access technology (IRAT) transition is provided. The method can include a wireless communication device determining a realized quality of service (QoS) for packet switched data traffic on a first radio access technology (RAT); determining whether the realized QoS satisfies a threshold QoS; suspending IRAT transition to a second RAT in an instance in which it is determined that the realized QoS satisfies the threshold QoS; and allowing IRAT transition to the second RAT in an instance in which it is determined that the realized QoS does not satisfy the threshold QoS.

1. A method for determining whether to allow performance of an inter-radio access technology (IRAT) transition, the method comprising a wireless communication device:
measuring a radio frequency (RF) parameter for triggering the IRAT transition from a first radio access technology (RAT) to a second RAT; determining whether the measured RF parameter falls below an RF measurement threshold for triggering the IRAT transition from the first RAT to the second RAT; determining a realized quality of service (QoS) for packet switched data traffic on the first RAT; determining whether the realized QoS satisfies a threshold QoS; suspending the IRAT transition from the first RAT to the second RAT in an instance in which it is determined that the realized QoS satisfies the threshold QoS and the measured RF parameter falls below the RF measurement threshold for triggering the IRAT transition; and allowing the IRAT transition from the first RAT to the second RAT in an instance in which it is determined that the realized QoS does not satisfy the threshold QoS and the measured RF parameter equals or exceeds the RF measurement threshold for triggering the IRAT transition.
