Abstract: PROBLEM TO BE SOLVED: To actualize a radio base station which enables both a point-to-point communication of user information and a point-to-multipoint communication of user information with a radio terminal viewed from a radio base station. SOLUTION: A 1st media access control identifier is allocated to a radio terminal 200 having made a request for connection (104), the correspondence between this identifier and the terminal is reported (102), and information addressed to the correspondent radio terminal is transmitted in the time slot corresponding to the identifier (105). Further, a 2nd media access control identifier is assigned to a multicast IP address that multiple radio terminals are wished to receive (104), the correspondence between the identifier and address is transmitted (102), and information that the radio terminals are wished to receive is transmitted in the time slot corresponding to the identifier (105).

Abstract: PROBLEM TO BE SOLVED: To transfer a packet including a payload, on which data having error durability are placed, in a radio environment by applying a first error correcting system to a part of plural packet segments and applying a second error correcting system different from the first system to the remaining segments. SOLUTION: The first error correcting system is applied to at least a part of plural packet segments and the second error correcting system different from the first error correcting system is applied to the remaining packet segments. Namely, a strong correcting code is loaded to the part including header parts 302-306 so that the errors generated on a radio transmission line can be almost completely removed. Besides, a weak error correcting code is loaded to a payload part (MPEG4 video 301) and even when a little error is left in the MPEG4 video part, the original error durability of the MPEG4 video can be effectively utilized.

Abstract: PROBLEM TO BE SOLVED: To accelerate hands-off control that accompanies movement by connecting and switching plural radio base stations, transferring datagram based on information about routing of a stored network layer and updating the information about routing at the time of detecting that a mobile terminal moves among radio base stations. SOLUTION: Mobile correspondence router devices (MSR) 220 and 221 are connected to an IP terminal 225 via a gateway(GW) 223 and the internet 224 and perform switching processing of an ATM cell with plural radio base stations. Also, the MSRs 220 and 221 each has functions, such as the management and storage of positional information, paging start and response, control of the detection and execution, etc., of responses, hands-off start decision processings, executions, etc. When the MSRs 220 and 221 detect that a mobile terminal 201 moves among radio base stations 202, 203 and 211, each stored information is updated. Thus, it is possible to perform hands-off control faster than an internet system.
