Radio communication system using point-to-point and point-to-multipoint user information communications
First Claim
1. A radio base station device, comprising:
- a reception unit configured to receive a connection request from one radio terminal;
a set up unit configures to set up a datalink connection with respect to said one radio terminal;
a first allocation unit configured to allocate a first media access control identifier which is an unused media access control identifier, to said one radio terminal that issued the connection request;
a broadcast unit configured to broadcast a correspondence between the first media access control identifier and said one radio terminal;
a second allocation unit configured to allocate a second media access control identifier to an identifier of a multicast information that are to be received by a plurality of radio terminals;
a first transmission unit configured to transmit a correspondence information for enabling said plurality of radio terminals to recognize a correspondence between the second media access control identifier and the identifier of the multicast information; and
a second transmission unit configured to transmit a time-slot corresponding to the first media access control identifier with a user information destined to said one radio terminal loaded thereon, and a time-slot corresponding to the second media access control identifier with the multicast information loaded thereon.

Abstract
An information communication scheme for enabling the radio base station to carry out both point-to-point user information communications and point-to-multipoint user information communications with respect to radio terminals is disclosed. A first media access control identifier is allocated to a radio terminal which made a connection request, a correspondence between the first media access identifier and the radio terminal is broadcast, and a user information destined to the radio terminal is transmitted using a time-slot corresponding to the first media access control identifier. On the other hand, a second media access control identifier is allocated to a multicast information identifier, a correspondence between the second media access control identifier and the multicast information identifier is transmitted, and the multicast information is transmitted using a time-slot corresonding to the second media access control identifier.

18. A method of information communication from a radio base station to a radio terminal, comprising the steps of:
-
making a connection request from the radio terminal to the radio base station;
setting up a datalink connection between the radio terminal and the radio base station;
allocating a first media access control identifier which is an unused media access control identifier, to the radio terminal, at the radio base station which received the connection request;
transmitting a correspondence between the first media access control identifier and the radio terminal, from the radio base station to the radio terminal;
transmitting a user information from the radio base station to the radio terminal using a time-slot corresponding to the first media access control identifier;
allocating a second media access control identifier to a multicast information to be received by a plurality of radio terminals, at the radio base station;
transmitting a correspondence information for enabling said plurality of radio terminals to recognize a correspondence between the second media access control identifier and the identifier of the multicast information; and
transmitting the multicast information from the radio base station to said plurality of radio terminals using a time-slot corresponding to the second media access control identifier.
