The present document describes a dynamic mobility management system. The disclosure describes a mobility management mechanism that is able to maintain the IP address assigned when a session was initiated in the user device to exchange data packets between the end-points of a given data service. This is possible through the management of the distributed mobility anchors, tunnels, interfaces and IP addresses, where a mobile node is configured to bind to the previously accessed mobility access router, such that the previously established network sessions of the mobile node are re-established through said previously accessed mobility access router. The disclosure is applied in the Information and Communication Technology domain, more precisely in the mobility management in communication networks.
