Abstract

In some instances, a terminal device may communication with the network infrequently. Therefore, in order to save system resources, a PDN or PDP connection associated with the terminal device may be revoked or deleted. Example embodiments presented herein are directed towards a gateway node and mobility management node for providing an improved means of re-establishing a previously revoked or deleted PDP/PDN connection in response to a downlink data notification.
