In the CDMA2000 system, when traditional C net and IMS (IP Multimedia System) network interworking, after the call through conversation, need MGCF (MGCF) network element in the traditional C net that the charge information of conversation is sent to CG (charging gateway) charging center in the IMS network, adopt Diameter to transmit charge information at present in the industry usually.
Stipulated that in the RFC3588 Diameter Diameter message route adopts the routing table mode based on the territory.All route queryings based on the territory all rely on the territory routing table to carry out.Territory routing table inlet comprises following field:
---domain name.This field is usually as the major key in the routing table inquiry.Notice that some practical application is based on the principle of " from the longest coupling of right-hand member " when carrying out inquiry, and do not require coupling fully.
---the application identities symbol.An application is identified by carrier ID and application ID.Carrier ID all is decided to be " 0 " at present.Route inlet may have different destinations based on the application identities AVP in the message (AttributeValue Pair, property value to).The application identities symbol must be as second key field of routing table inquiry.
---local action.Local action field is used for identifying a message and will how be handled.Support following action:
LOCAL (this locality)-this locality action is set to the Diameter message of LOCAL and can handles in this locality, need not to be routed to other server.
RELAY (relaying)-all Diameter message that belong to this type must be routed to the server of next jumping, need not to revise any non-route AVP.
PROXY (agency)-all Diameter message that belong to this type must be routed to the server of next jumping.Home server can be carried out local policy by new AVP is inserted in this message before route.
REDIRECT (being redirected)-all Diameter message that belong to this type must be added the sign of ownership Diameter server, and return to the sender of message.
