Mobile communication system and packet processing method thereof
First Claim
1. A packet data serving node (PDSN) comprising an interconnection with a service providing server and a base station/packet control function (BS/PCF), wherein the PDSN analyzes an Internet Protocol (IP) packet received from the service providing server, and marks the IP packet for transmission over a short data burst (SDB) channel and transmits the marked IP packet to the BS/PCF when the IP packet is selected as a packet to be transmitted over the SDB channel.

Abstract
A mobile communication system and a packet processing method thereof are provided. A packet data serving node (PDSN) analyzes an Internet Protocol (IP) packet received from a service providing server, and if the IP packet is selected to be transmitted over a short data burst (SDB) channel, marks the IP packet for transmission over the short data burst (SDB) channel and transmits it to a base station/packet control function (BS/PCF).

10. A mobile communication system, comprising:
-
a service providing server for inserting indication information for transmitting an Internet Protocol (IP) packet received from the Internet over a short data burst (SDB) channel into a header of the IP packet and transmitting the IP packet; and
a packet data serving node (PDSN) for receiving the IP packet from the service providing server, analyzing the IP packet, marking the IP packet to be transmitted over the SDB channel when the IP packet is to be transmitted over the SDB channel, and transmitting the marked IP packet to a base station/packet control function (BS/PCF). - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

- 18. A service providing server producing an IP packet comprising a signaling message for session establishment, wherein indication information for transmitting the IP packet over an SDB channel is set in a predetermined field of the IP packet when the signaling message is received from a mobile station via an IP network.
-
20. A packet processing method of a mobile communication system, comprising the steps of:
-
inserting indication information for transmitting an IP packet over a short data burst (SDB) channel into a header of the IP packet comprising signaling messages for session establishment;
transmitting the IP packet;
receiving the IP packet from a service providing server; and
analyzing the indication information to determine whether the IP packet is to be transmitted over the SDB channel. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)

29. A packet processing method of a mobile communication system, the method comprising the steps of:
-
storing an Internet Protocol (IP) address list of a service providing server and an allowable range of a total packet length;
inserting indication information for transmitting an IP packet over a short data burst (SDB) channel into a header of the IP packet comprising signaling messages for session establishment;
transmitting the IP packet;
extracting a source IP address from the IP packet received from the service providing server;
determining whether the source IP address matches a stored IP address of the service providing server;
marking the IP packet to be transmitted over the SDB channel; and
transmitting the marked IP packet to a base station/packet control function (BS/PCF) when the IP packet is selected to be transmitted over the SDB channel.

-
30. A packet processing method of a PDSN, the method comprising the steps of:
-
reading out a source Internet Protocol (IP) address from a header of an IP packet received from the Internet;
determining whether a previously stored list of a service providing server comprises an address matching the source IP address;
determining whether the header of the IP packet comprises an option field when the previously stored list of a service providing server comprises the address matching the source IP address;
determining whether a value of the option field is effective when the header of the IP packet comprises the option field; and
marking an indicator for transmitting over an SDB channel onto a predetermined field of a generic routing encapsulation (GRE) header when the value of the option field is effective. - View Dependent Claims (31, 32)
