1. A base station comprising:
- an interface to each of a plurality of backbone networks including a first network and a second network, wherein the second network is a virtual network including at least one virtual MME (Mobility Management Entity) as a network function corresponding to an MME of the first network;
a first controller that is configured to select either the MME of the first network or the virtual MME of the second network, based on whether predetermined information is included in a message sent from a terminal; and
a second controller that is configured to send a connection request sent from the terminal to the virtual MME when the predetermined information is included in the message.

Abstract
A technique that can enhance the effectiveness of traffic offloading is provided. A base station of the present invention includes: a first means for selecting an MME (Mobility Management Entity), based on information included in a message sent from a terminal; and a second means for sending a connection request sent from the terminal to the selected MME, wherein the first means is able to select a virtual MME that operates a function of the MME through a virtual machine, based on the information included in the message.

14. An MME (Mobility Management Entity) capable of communicating with a base station, that is connected to a plurality of backbone networks including a first network and a second network, wherein the first network includes the MME, wherein the second network is a virtual network including at least one virtual MME as a network function corresponding to the MME, the MME comprising:
-
a first controller that is configured to select either the MME of the first network or the virtual MME of the second network, based on whether predetermined information is included in a message sent from a terminal; and a second controller that is configured to instruct the base station to send a connection request to the virtual MME when the message includes the predetermined information. - View Dependent Claims (15, 16, 17, 18, 19)
