US 11,778,046 B2 · Virtualized communication device and method therefor

Abstract

An object is to provide a communication system capable of preventing a number of control signals, which could occur in a mobile communication network, from occurring when a VM is deleted in a node device without suspending a service. A communication system according to the present invention includes a communication device 1, and a communication device 2 configured to control a plurality of sessions set between the communication devices 1 and 2 by using a plurality of VMs, in which the communication device 2 notifies, by using a determination that a plurality of sessions that are controlled between the communication device 1 and a VM 3 should be controlled in a VM 4 different from the VM 3 as a trigger, the communication device 1 of identification information used in the VM 4 and updates the sessions.

Claims2

Dependent claims

A first virtualized communication device used in a mobile communication system, the first virtualized communication device comprising:

a controller configured to establish a session between communication devices;
and
a transmitter configured to send information about a second virtualized communication device configured to establish a session between communication devices to a mobility management device configured to perform mobility management of a terminal device,
wherein the transmitter sends information about the second virtualized communication device for establishing a new session between communication devices to the mobility management device during a transfer procedure from the first virtualized communication device to the second virtualized communication device, and
wherein the controller releases the session established by the first virtualized communication device after the new session is re-established by the second virtualized communication device identified by the information.
