Claim:
1. A method of selectively caching Quality of Service (QoS) data at an apparatus, comprising: detecting a first transition of a client device from an active state to an idle state while the client device is allocated a QoS link by a serving network; caching QoS information associated with the QoS link, wherein the cached QoS information includes one or more parameters of an interface between different core network components of the core network; releasing the QoS link in response to the detection of the first transition; detecting, after the caching and releasing, a second transition of the client device from the idle state back to the active state; and re-establishing, in response to the detection of the second transition and subsequent to the client device being in the active state, the QoS link using the cached QoS information.
