Abstract
Provided are a method, device and system for implementing address sharing. An address pool configured for unified management over IP addresses is configured on an AAA server; and the AAA server may allocate an IP address to a CGN device according to the configured address pool. By such a technology for implementing address sharing in the present disclosure, IP address resource sharing among CGN devices is implemented, so that problems about resource load sharing among the CGN devices may be solved, a sharing rate of IP address resources is increased, and resource optimization may be implemented; and moreover, in terms of IP address management, a more available platform is provided for an operating company. In addition, the IP addresses are managed by the AAA server in a unified manner, and then the address pool is not required to be configured on the CGN device, so that the CGN device may be started without any address pool.

20. A system for implementing address sharing, comprising an Authentication, Authorization and Accounting (AAA) server and a Carrier Grade Network Address Translation (CGN) device, wherein
the AAA server is configured with an address pool configured for unified management over Internet Protocol (IP) addresses, and the AAA server is configured to allocate an IP address to the CGN device according to the address pool; - and
the CGN device is configured to interact with the AAA server and perform IP address management comprising application and/or releasing of the IP addresses; wherein the AAA server comprises an AAA server management module, configured to perform management as follows; address pool management; priority privilege management; and loci management; the CGN device comprises a user configuration module, an IP address resource requesting/releasing module and an IP address resource management module, wherein the user configuration module is configured to perform configuration involving a sharing policy;
the sharing policy comprises at least one of following;
priority, a threshold and a step size;the IP address resource requesting/releasing module is configured to calculate a resource idleness rate and request/release the IP address according to the resource idleness rate; and the IP address resource management module is configured to manage an IP address resource.
