Abstract

A mobile communication system includes a mobile communication network connected to a core network (CN) and a plurality of radio network nodes included in the mobile communication network (RAN). Network resources for a data flow between a data transmission node and a data reception node that passes through the CN and RAN are reserved on the basis of RSVP. A region for refreshing a reservation state of network resources concerning the flow is divided into a CN side and an RAN side by taking a predetermined radio network node through which the flow passes as a boundary. Refreshment on the RAN side is conducted with a frequency higher than that of refreshment on the CN side.

Dependent claims

A mobile communication system using a resource reservation protocol comprising:

a mobile communication network connected to a core network implementing a resource reservation protocol;
a plurality of radio network nodes included in the mobile communication network;
means for reserving network resources for a data flow between a data transmission node and a data reception node that passes through the core network and the mobile communication network, on the basis of a resource reservation protocol;
and
refresh control means for dividing a region for refreshing a reservation state of network resources concerning the flow into a core network side and a mobile communication network side by taking a predetermined radio network node through which the flow passes as a boundary, and conducting refreshment on the mobile communication network side with a frequency higher than that of refreshment on the core network side.
