System and method for diameter prefix authorization

A system for Diameter Application for prefix authorization, the system comprising:

• a Prefix-Authorization (PA) client having a processor, memory coupled to the processor, and a network interface configured to communicate with a Prefix-Authorization (PA) server, wherein the PA server uses Diameter Prefix Authorization for Diameter prefix authorization to the PA client, wherein
• the PA client is configured to send a request for a prefix to the PA server,
• the PA client is configured to receive an answer message from the PA server, the answer message having a first prefix with a first lifetime,
• the PA client is configured to communicate with at least one PA user,
• the PA client is configured to request a reduced lifetime of the first prefix from the PA server,
• the PA client is configured to receive an answer message from the PA server, wherein the answer message includes a reduced first lifetime of the first prefix, which is a non-zero value less than the first lifetime, wherein the PA server comprises an AAA server with Diameter Extensible Authentication protocol (EAP) for authentication and an AAA server with PA for Diameter prefix authorization.

A Device for Diameter Application for prefix authorization, the device

• comprising a processor, at least two or more network interfaces, and a memory coupled with the processor, and the memory comprising a non-transitory computer-readable medium having a computer-readable program embodied therein for directing operation of the device, the computer readable program including:
• instructions for sending a request message for prefix authorization;
• and
• instructions for receiving an answer message, the answer message comprising a first prefix with a first lifetime;
• instructions for a client sending a request for a reduced lifetime of the first prefix to a server;
• and
• instructions for receiving an answer message comprising the reduced lifetime of the first prefix, wherein the answer message includes a reduced first lifetime of the first prefix, which is a non-zero value less than the first lifetime, wherein the PA server comprises an AAA server with Diameter Extensible Authentication protocol (EAP) for authentication and an AAA server with PA for Diameter prefix authorization.

A method of operating a Prefix Authorization (PA) server for Diameter prefix authorization, the method comprising:

• receiving a request for a prefix from a PA client;
• replying with an answer message to the PA client to provide a first prefix with a first lifetime in response to the request;
• receiving a request from the PA client for a reduced first lifetime of the first prefix;
• and
• replying with an answer message to the PA client to provide a reduced first lifetime of the first prefix in response to the request for the reduced first lifetime, the reduced first lifetime of the first prefix being a non-zero value less than the first lifetime, wherein the PA server comprises an AAA server with Diameter Extensible Authentication protocol (EAP) for authentication and an AAA server with PA for Diameter prefix authorization.

A system for Diameter Application for prefix authorization, the system comprising:

• a Prefix-Authorization (PA) server having a processor, memory coupled to the processor, and a network interface, wherein the PA server uses Diameter Prefix Authorization for Diameter prefix authorization to a PA client, the Diameter prefix authorization comprising:
• instructions to receive a request for prefix by a Prefix Authorization (PA) client;
• and
• instructions to reply with an answer message by the PA server to the PA client to provide a first prefix with a first lifetime,
• instructions to receive a request for a reduced first lifetime for the first prefix from the PA client,
• instructions to reply with an answer message by the PA server to the PA client to provide a reduced first lifetime for the first prefix, wherein the answer message includes a reduced first lifetime of the first prefix, which is a non-zero value less than the first lifetime, wherein the PA server comprises an AAA server with Diameter Extensible Authentication protocol (EAP) for authentication and an AAA server with PA for Diameter prefix authorization.

A Prefix-Authorization (PA) server device configured to:

• run a Diameter Authentication Protocol;
• receive a prefix authorize request command from a Prefix Authorization (PA) client when the PA client requests a new prefix;
• transmit a prefix authorize answer commend to the PA client, the prefix authorize command comprising a prefix with a lifetime in response to a request for a new prefix and a reduced lifetime of an old prefix in response to a request for a reduction of the lifetime of the old prefix, wherein the reduced lifetime of the old prefix is a non-zero value less than the lifetime of the old prefix;
• receive a prefix authorize release commend from the PA client, the prefix authorize release command signaling a request to return a prefix to the PA server device;
• receive a prefix authorize renew commend from the PA client when the PA client requests, to renew a prefix and when the PA client requests a reduction of a lifetime of an old prefix;
• and
• transmit a prefix authorize reconfigure command to the PA client, the prefix authorize reconfigure command signaling the PA client to renew old prefixes or get new prefixes for renumbering, wherein the PA server device comprises a processor, memory coupled to the processor, and a network interface, wherein the PA server device comprises an AAA server with Diameter Extensible Authentication protocol (EAP) for authentication and an AAA server with PA for Diameter prefix authorization.

A Prefix-Authorization (PA) client device configured to:

• run a Diameter Authentication Protocol;
• transmit a prefix authorize request command to a Prefix Authorization (PA) server when the PA client device requests a new prefix;
• receive a prefix authorize answer commend from the PA server, the prefix authorize command comprising a prefix with a lifetime in response to a request for a new prefix and a reduced lifetime of an old prefix in response to a request for a reduction of the lifetime of the old prefix, wherein the reduced lifetime of the old prefix is a non-zero value less than the lifetime of the old prefix;
• transmit a prefix authorize release commend to the PA server, the prefix authorize release command signaling a request to return a prefix to the PA server;
• transmit a prefix authorize renew commend to the PA server when the PA client device requests to renew a prefix and when PA client device requests a reduction of a lifetime of an old prefix;
• and
• receive a prefix authorize reconfigure command from the PA server, the prefix authorize reconfigure command signaling the PA client device to renew old prefixes or get new prefixes for renumbering, wherein the PA client device comprises a processor, memory coupled to the processor, and a network interface, wherein the PA server comprises an AAA server with Diameter Extensible Authentication protocol (EAP) for authentication and an AAA server with PA for Diameter prefix authorization.
