Abstract
There is provided a converged access control method using a network access device at an edge node of an IP network of a convergence ALL-IP network that performs authentication control, QoS control, traffic control and mobility control in a consistent manner using a network access device located at penetration nodes of an IP network of a convergence ALL-IP network to effectively accommodate a subscriber network in various access environments, thereby ensuring network flexibility and scalability.
Claims13
An authentication method using a network access device at an edge node of an IP network of a convergence ALL-IP network, the authentication method comprising:
- acquiring, by the network access device, authentication information, when a terminal performs handover, by intercepting the authentication information being transmitted and received through the network access device when terminal information-based authentication in L2-level is performed between an authentication server and a wireless access device connected to the terminal being handed over;
- and
- allowing, by the network access device, transferral of a data packet corresponding to the terminal having the authentication information.
A QoS control method using a network access device at an edge node of an IP network of a convergence ALL-IP network, the QoS control method comprising:
- controlling, by the network access device, QoS of downlink traffic on the basis of the amount of radio resources allocated;
- and
- controlling, by the network access device, controlling QoS of uplink traffic according to bandwidth information acquirable from call control signaling or a service-specific resource allocation policy.
A traffic control method using an authentication server, a policy server, a network control device and a network access device in a convergence ALL-IP network, the traffic control method using the network access device comprising:
- providing, by the authentication server, authentication information about a user, having completed authentication, to the policy server and the network control device;
- setting previous usage and a total amount of traffic allowed, corresponding to the user's authentication information, in the network access device while the policy server and the network control device interoperate with each other;
- and
- tracking, by the network access device, the user's traffic usage to update the previous usage, and performing traffic control of a terminal whose updated previous usage exceeds the total amount of traffic allowed.
An IP mobility control method using a network access device at an edge node of an IP network of a convergence ALL-IP network to provide IP mobility control services between an IP terminal having a mobility control client mounted therein and a general terminal not having a mobility control client, the IP mobility control method comprising:
- obtaining, by the network access device, terminal information and location information of the general terminal and data tunnel information of a radio section, and registering the obtained information in an IP mobility control server;
- establishing, by the network access device, mapping between a data tunnel of an IP network section and a data tunnel of a radio section when a request for communications with the general terminal is made so that the data tunnel of the IP network section is formed to perform communications with the general terminal;
- and
- obtaining the changed location information of the general terminal and the changed data tunnel information of the radio section when the general terminal is handed over, informing the IP mobility control server of the obtained information, and establishing mapping between the data tunnel of the IP network section and the changed data tunnel of the radio section.
