Abstract
A configuration is such that among EPC nodes such as an S-GWand a P-GW, which form an EPC network, a DNS serverselects the EPC node to use based on a selection priority in a DNS resource record registered to the DNS serverto thereby distribute loads of the EPC nodes. Further, each of the EPC nodes has a function to transmit, to the DNS server, an update request for the DNS resource record in order to lower the selection priority of the DNS resource record relating to the EPC node when the EPC node detects that resource usage of the own EPC node is approaching to an overloaded state. Meanwhile, in response to the update request, the DNS serverdynamically updates the DNS resource record, when the DNS serverreceives the update request from the EPC node.
