Abstract

This invention describes how combined session and resource tracking in a mobile node (MN) and/or base station in dynamic network resource environment (Fig. 8) can be used to control reactions to resource shortage (800a). The session that is to experience a resource shortage is detected either by the MN (802a), or communicated to the MN where session signaling is used to modify the session according to MN and base station policy/configuration. The base station can alternatively modify the session itself with all the session peers, on behalf of the MN (890). The specific new reaction to resource shortages that is then enabled is to place the session on hold (830) such that the resources are freed, but so that the session state is maintained in the peers. This is preferable to dropping the session, as is generally the case in dynamic environments, if the likely period of resource loss is short and the session modifications require less overhead than restarting the session when the resources return after dropping the session. In addition, before having resources removed, the base station can provide the MN with an opportunity to upgrade the priority of its resource request (820) compared to other users in the cell, so that a resource reaction auction is conducted to decide which MN actually loses its resources.
