Method and apparatus for policy and charging rule functional entity information maintenance

Abstract

The invention discloses strategy and accounting rule function entity information maintenance methods and a device thereof. One method comprises that under a non-roaming situation, a diameter routing agent (DRA) receives the information sent by network appliances for performing a session ending operation, after determining to delete PCRF information, the DRA deletes the RCRF information storied therein corresponding to the information carried in the message. The other method comprises that under a roaming situation, DRA of a home network receives the information sent by a visiting network for performing a session ending operation, after determining that the information carried in the message needs deleting, the DRA of a home network deletes the home network RCRF information storied therein corresponding to the information carried in the message. Therefore, spamming in DRA can be deleted in time when the session is ended, effect of spamming on the maintenance of DRA information can be avoided and overflow of the memory space of DRA can also be avoided.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and device for maintaining policy and charging rule functional entity information. Background technique [0002] In an evolved network such as a network in which a mobile communication network and broadband wireless access technologies are integrated, one PCRF Realm (PCRF domain, Policy and Charging Rule Function, policy and charging rule functional entity) may include multiple PCRFs. PCRF Realm is managed by DRA (Diameter Routing Agent, Diameter Routing Agent). In the process of establishing a session between devices such as a GW (gateway), an AF (application server) and the PCRF, the GW and the AF need to query the DRA to obtain PCRF information. [0003] In the process of realizing the present invention, the inventors found that the DRA stores PCRF information, such as the correspondence between terminals and PCRFs. Useless junk information exi...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that: DRA stores PCRF information such as the corresponding relationship between terminals and PCRFs. As the number of terminal visits increases, more and more PCRF information is stored in DRA. However, DRA There are useless garbage information in the PCRF information stored in the DRA, which will make DRA information maintenance very difficult and easily cause DRA storage space to overflow
