Title:
GATEWAY APPARATUS
Document Type and Number:
Japanese Patent JP3923977
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To reduce fluctuation in an arrival time of a reception acknowledgement signal at a transmission source and to prevent an increase in traffic in a radio channel.
SOLUTION: A mobile exchange center 5 is provided with a gateway apparatus 10 having a packet relay processing means 11 for applying relay processing to a TCP packet, and a re-transmission processing means 12 for applying re-transmission processing to a radio communication unit. The packet relay processing means 11 transmits a reception acknowledgement signal with respect to an outgoing TCP packet, while being set to an incoming TCP packet. In the case that no incoming TCP packet is transmitted until a prescribed timer expires, the packet relay processing means 11 transmits the reception acknowledgement signal with respect to the outgoing TCP packet on behalf of the radio communication unit.
