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.

Abstract
The present invention introduces system, apparatus and method that reduce wastage of network resources and mobile phone resources. The mobile phone would indicate its status in a tracking area update message when it is connected to the device. The network can then understand from the status indication that the mobile phone is capable of delivering packets to the device, and would thus allow the server to initiate communications. An absence of the status indication would imply the mobile phone is not capable of delivering packets to the device, and the network would then disallow the server to initiate communications.

6. A serving gateway that triggers a Mobility Management Entity (MME) to page a mobile node in idle state, the serving gateway comprising:
-
a receiver which, in operation, receives from a server a downlink data packet for the mobile node on a bearer; and a sender which, in operation, sends a Downlink Data Notification (DDN) message including bearer Identification (ID) of said bearer to the MME; wherein the receiver, in operation, receives a Delay Downlink Packet Notification Request (DDPNR) from the MME when the MME determines to limit the number of the DDN messages that the MME receives, and wherein after the receiver receives the DDPNR the sender, in operation, sends a new DDN message to the MME only when the receiver receives a new downlink data packet on a bearer having higher priority than a configured threshold priority level. - View Dependent Claims (7, 8, 9, 10, 11)

12. A Mobility Management Entity (MME) comprising:
-
a receiver which, in operation, receives a Downlink Data Notification (DDN) message including bearer Identification (ID) of a bearer from a serving gateway, which has received from a server a downlink data packet for a mobile node on said bearer; a controller which, in operation, determines to limit the number of the DDN messages that the MME receives from the serving gateway; and a transmitter which, in operation, transmits a Delay Downlink Packet Notification Request (DDPNR) to the serving gateway when the controller determines to limit the number of the DDN messages that the MME receives, the DDPNR triggering the serving gateway to send 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. - View Dependent Claims (13, 14, 15, 16, 17)
