Title:
COMMUNICATION SYSTEM, COMMUNICATION METHOD, RADIO TERMINAL, RADIO RELAY DEVICE, AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/023781
Kind Code:
A1
Abstract:
Disclosed is a technique to effectively use a network resource when a radio terminal of
the transmission side and a radio terminal of the reception side are radio-connected to
the same radio relay device, to reduce the load on a control device, and to manage communication
of the radio terminals by the control device. According to the technique, when
the UE (2) of the reception side is connected to the same E-Node B (103), the UE (1)
of the transmission side divides the transmission packet destined to the UE (2)
into a first packet not to be relayed by an ACGW (105) and a second packet to be relayed
by the ACGW (105) and transmits them to the E-Node B (103). The E-Node B (103) transmits
the first packet to the UE (2) and transmits the second packet to the ACGW (105).The
ACGW (105) receives the second packet and transmits it to the E-Node B (103). The
E-Node B (103) receives the second packet transmitted from the ACGW (105) and
transmits it to the UE (2). The UE (2) receives the first and the second packet
and combines them into the original packet.
