Abstract: PROBLEM TO BE SOLVED: To make flow identification information available to the entire routing by receiving an IP packet including a destination address corresponding to the home address of a moving body node, removing the home address of the moving body node from the header of the IP packet, replacing it to correct the IP packet and a moving body node identifier to the IP packet to transmit it. SOLUTION: A home agent removes the destination address 62 of a moving body node in a home network, replaces it with the destination address of a moving body node in a foreign network and fits an IP packet. A new IP packet 42 includes the payload 63 of the original IP packet 50, a source address 60 and a source protocol ID 66. The destination address 62 of the original IP packet is replaced with a new destination address 41. This assembled new IP packet is transmitted to care of address in the foreign network.

Abstract: PROBLEM TO BE SOLVED: To support a service quality request decided by a message transmission source over the entire routing path by generating a correction response message having the address of a communication node as a destination address in an external network and transmitting the correction response message. SOLUTION: After a mobile node 8 moves to an external network 6, an original c/o address is allocated to the mobile node 8, and the node 8 is registered directly with the home agent of a home network. An IP packet generated by a communication node 10 is the same in spite of whether the node 8 is located within the home network 2 or within the network 6. A mobile IP performing route optimization requests the node 10 to find where the node 8 is located at the current time. The node 8 is registered with the home agent by using the current c/o address.

Abstract: PROBLEM TO BE SOLVED: To provide a mobile telephone system with a new architecture capable of processing voice Internet protocol traffic. SOLUTION: In the system, real time traffic from a mobile station (22) is processed in routing by Internet protocol core (20) of public terrestrial mobile telephone connected to either of media gateways (28, 32). The gateways (28, 32) provide services of public switching telephone network/integrated service digital network (26) and Internet protocol backbone (30), the services are provided without through GPRS gateway.

Abstract: PROBLEM TO BE SOLVED: To provide an enhanced real time data transmission system and its method. SOLUTION: The real time data transmission method used in a network consisting of a mobile station 22, a wireless network controller 24, a destination station 26, and call control systems 38, 39 and of real time media gateways 28, 32 that attains access to an Internet backbone section 30 in addition to gateways specific to a general packet radio system(GPRS), includes processing where a header of a real time data stream is changed when the real time data stream passes through the network so that the real time data stream is directly sent to the real time gateway without passing through a gateway specific to the GPRS.

Abstract: There is disclosed a method of establishing a quality of service session between a correspondent node and a mobile node. The mobile node has a home address in a home network is temporarily connected at a care-of address in a foreign network. The method includes the steps of generating, in the foreign network, a modified reply message having a source address of the mobile node's care-of address and a destination address of the correspondent node, and transmitting the modified reply message. A mobile IP environment capable of supporting such a quality of service session is also disclosed.

Abstract: A real time data transmission method is used in a network in which a real time media gateway is provided to allow access to the internet backbone in addition to the usual GPRS specific gateway. The method involves changing the header in a real time data stream as it passes through the network so that it can pass directly to the real time gateway without passing through the GPRS specific gateway. This ensures that the data stream travels along a more direct route and shortens the headers used in the data stream in the process.

Abstract: There is provided a method of directing an internet protocol IP packet to a mobile node. The mobile node has a home address in a home network and is temporarily connectable in a foreign network having a foreign agent. The IP packet has a header portion including the destination address to which the IP packet is to be sent. The method comprises the steps of: receiving, in the home network, the IP packet including a destination address corresponding to the home address of the mobile node; modifying the IP packet by: removing the home address of the mobile node from the header portion of the IP packet and replacing it with the foreign agent care-of address; appending a mobile node identifier to the IP packet; and transmitting the modified IP packet.
