Method of dynamically adjusting quality of service (QoS) targets

摘要

A method of dynamically adjusting quality of service targets for applications and/or subscribers of wireless communication, by reducing or increasing quality of service targets for a group of applications based on overload or under load detection, in order to ensure that actually achieved quality of service levels are adequate, especially when supporting emergency service users.

1. A method of managing air interface resources in a wireless network of the kind in which subscriptions to different levels of service are available for different applications and at least a first and a second class of applications compete with each other for bandwidth resources allocated by an allocation algorithm, comprising:
receiving an indication that an overload has been detected; in response to the received overload indication, reducing one or more QoS targets for at least one class of application being served by the wireless network, wherein each QoS target is a prescribed level of network performance to be experienced by a user if sufficient resources can be allocated; and communicating the one or more reduced QoS targets, thereby to initiate a reallocation of dedicated air interface bandwidth resources between at least the first and second classes that brings the network performance closer to the level specified by the current QoS targets, including said reduced one or more targets.
