Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0030] The communication system according to the present embodiment is a 3GPP mobile communication system providing MBMS. figure 1 It is a block diagram showing the structure of the 3GPP mobile communication system. refer to figure 1 , the 3GPP mobile communication system is composed of a core network (CN) 11 and an access network (UTRAN; UMTS Terrestrial Radio Access Network) 12 .

[0031] CN 11 is a network realizing packet communication through packet network 13 and has GGSN (Gateway GPRS Support Node) 14 connected to packet network 13 and SGSN (Serving GPRS Support Node) 15 connected to GGSN 14 .

[0032] UTRAN 12 is an access network for radio mobile communications, and has RNC (Radio Network Controller) 16 and base station equipment (Node B) 17 .

[0033] Although the Node B 17 actually transmits radio waves to the UE 18, the RNC 16 notif...

Abstract

A terminal management means holds in a context for managing terminal information, information relating to a terminal which participates in a distribution service provided in each cell. A terminal quantity counting means counts in the service unit, the number of terminals participating in the distribution service in each cell by using the context held in the terminal management means. A bearer check means determines whether to use a point-to-point bearer or a point-to-multipoint bearer for the distribution service in each cell in accordance with the number of terminals counted by the terminal quantity counting means.

Description

technical field [0001] The present invention relates to a communication system capable of selecting the type of carrier used to deliver a service. Background technique [0002] In MBMS (Multimedia Broadcast Multicast Service) of a mobile communication system, data is delivered to a plurality of mobile terminals (UE: User Equipment) by broadcast or multicast. Data is transferred according to a p-t-p (point-to-point) system or a p-t-m (point-to-multipoint) system. The p-t-p system is a one-to-one communication system while the p-t-m system is a one-to-many communication system. [0003] As for the type of carrier on the radio channel used for data communication, there is a carrier dedicated to the p-t-p system (p-t-p carrier) and a carrier dedicated to the p-t-m system (p-t-m carrier). In MBMS, one type of carrier can be changed to another according to conditions during service. [0004] A p-t-m carrier is established as a common carrier on the radio channel. Therefore, if...
