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.

Claims

1-19. -19. (canceled)

20. A method for paging a mobile node in idle state comprising the steps of:

sending, by a serving gateway, a Downlink Data Notification message including bearer ID of a bearer to a MME when the serving gateway receives a downlink data packet for the mobile node on the bearer;

sending, by the MME, a Downlink Data Notification response to the serving gateway, the Downlink Data Notification response comprising information requesting to reduce the number of Downlink Data Notification messages; and

sending, by the serving gateway, a new Downlink Data Notification message to the MME, only when the serving gateway receives a new downlink data packet on a bearer with higher priority than the bearer.

21. The method for paging the mobile node according to claim 20, wherein the information requesting to reduce the number of Downlink Data Notification messages comprises delay information.

22. A serving gateway for triggering a MME to page a mobile node in idle state, the serving gateway comprising;

a data receiving unit configured to receive a downlink data packet for the mobile node on a bearer;

a sending unit configured to send a Downlink Data Notification message including bearer ID of the bearer to the MME; and

a receiving unit configured to receive a Downlink Data Notification response from the MME, the Downlink Data Notification response comprising information requesting to reduce the number of Downlink Data Notification messages,

wherein the sending unit sends a new Downlink Data Notification message to the MME, only when the serving gateway receives a new downlink data packet on a bearer with higher priority than the bearer.

23. The serving gateway according to claim 22, wherein the information requesting to reduce the number of Downlink Data Notification messages comprises delay information.
