1. A method comprising:
- (a) employing, a network element (NE) that is communicatively coupled between a plurality of cellular devices (CDs) via a cellular network and a plurality of servers via an Internet Protocol (IP) network; and
(b) configuring the NE for;
obtaining a control message sent from a first server, from the plurality of servers, toward a first CD from the plurality of CDs;
determining whether the first CD is in idle mode by comparing the time interval between the current time (CT), in which the control message was obtained, and the time value that is stored in a last timestamp register (LTSR) and indicates the time in which the last packet from the first CD had been obtained, if the time interval is bigger than a defined time out (TO) the first CD is considered to be in idle mode;
storing, upon determining that the first CD is in idle mode, the obtained control message in a computer memory device that is associated with the NE;
determining that another IP packet is sent toward the first CD; and
transferring the stored control message in association with the another IP packet toward the first CD via the cellular network;
(c) wherein storing the obtained control message saves the needs to reestablish the radio connection with the first CD, which is considered to be in idle mode.

Abstract
A technique for saving cellular resources is disclosed. The technique is implemented at an intermediate network element (NE) that is communicatively coupled between a plurality of cellular devices (CDs) via a cellular network and a plurality of servers via an Internet Protocol (IP) network. The NE is configured to transfer control packets in association with IP packets toward the CD in order to save cellular resources.

8. A method comprising:
-
(a) employing, a network element (NE) that is communicatively coupled between a plurality of cellular devices (CDs) via a cellular network and a plurality of servers via an Internet Protocol (IP) network; and (b) configuring the NE for determining when a first CD from the plurality of CDs is in idle mode by comparing the time interval between the current time (CT), in which a control message is obtained, and the time value that is stored in a last timestamp register (LTSR) and indicates the time in which the last packet from the first CD had been obtained, if the time interval is bigger than a defined time out (TO) the first CD is considered to be in idle mode; and (c) storing, upon determining that the first CD is in idle mode, the obtained control message in a computer memory device that is associated with the NE; (d) receiving an IP packet which is sent toward the first CD; and (e) transferring the stored control message in association with the received IP packet toward the first CD via the cellular network.

9. A computer readable memory device comprising instructions,
which when executed cause a processor, at network element (NE) that is communicatively coupled between a plurality of cellular-device (CDs) over a cellular network and a plurality of web servers over an IP network, for: -
a. obtaining a control message sent from a first Webserver, from the plurality of webservers, toward a first CD from the plurality of CDs; b. determining whether the first CD is in idle mode by comparing the time interval between the current time (CT), in which the control message was obtained, and the time value that is stored in a last timestamp register (LTSR) and indicates the time in which the last packet from the first CD had been obtained, if the time interval bigger than a defined time out (TO) the first CD is considered to be in idle mode; c. storing, upon determining that the first CD is in idle mode, the obtained control message in a computer memory device that is associated with the NE; d. receiving an IP packet for the first CD; e. in response to receiving the IP packet, the NE transferring the stored control message toward the first CD along with the received IP packet; and f. transferring the stored control message toward the first CD via the cellular network, whereby communications are delivered to the first CD more efficiently; and g. wherein storing the obtained control message saves the needs to reestablish the radio connection with the first CD, which is considered to be in idle mode. - View Dependent Claims (10, 11, 12, 13, 14, 15)
