Different types of traffic requiring different inactivity timer settings are assigned to different bearers or to different QoS classes. Different inactivity timer settings are established for different traffic types. Individual bearers or individual QoS classes are linked to a corresponding inactivity timer profile. The link may be accomplished in a number of ways. For example, an additional QoS parameter may be employed in a 3GPP QoS profile, or a new QoS class identifier may be mapped to an inactivity timer setting. Different inactivity timer settings allows both UE battery power conservation to be prioritized for some traffic and end-user experience (quick subsequent response times) to be prioritized for other traffic.
