Abstract:
1. A method for paging a mobile node in idle state comprising: receiving, from a server by a serving gateway, a downlink data packet for the mobile node on a bearer; sending, by the serving gateway, a Downlink Data Notification (DDN) message including bearer Identification (ID) of said bearer to a Mobility Management Entity (MME); sending, by the MME, a Delay Downlink Packet Notification Request (DDPNR) to the serving gateway when the MME determines to limit the number of the DDN messages that the MME receives from the serving gateway; and sending, by the serving gateway that has received the DDPNR, a new DDN message to the MME only when the serving gateway receives a new downlink data packet on a bearer having higher priority than a configured threshold priority level.
