Description
Technical field
The present invention relates to the communications field, particularly, relate to a kind of roam charging method and device, proxy call conversation control function entity (Proxy-Call Session ControlFunction, abbreviate P-CSCF as), service call session control function entity (Serving-CSCF abbreviates S-CSCF as).
Background technology
Present IP Multimedia System (Internet Protocol MultimediaSubsystem, abbreviating IMS as) roam charge charges according to 3GPP and the description of traffic criteria is handled, its processing procedure realizes by operator's sign (Inter OperatorIdentifier abbreviates IOI as) between net.IOI is the unique identifier of the overall situation, and shares between transmission and reception network, and it is made up of a pair of IOI: initiator IOI (Orig-IOI) and recipient IOI (Term-IOI).For initiating network, in request, produce Orig-IOI, from response, receive Term-IOI.For the recipient, receive and maintenance Orig-IOI the response that produces Term-IOI then.IOI has following three types:
First kind of IOI (Type 1IOI): at Session initiation Protocol (Session InitiationProtocol, abbreviate SIP as) in the message registration process, this IOI is present in proxy call conversation control function entity (Proxy-Call Session Control Function, abbreviate P-CSCF as) between the accesses network at place and the home network at service call session control function entity (Serving-CSCF abbreviates S-CSCF as) place; P-CSCF produces Orig-IOI, the record access network information, and S-CSCF produces Term-IOI, record home network information.
Second kind of IOI (Type 2IOI): be present between the S-CSCF that initiates network and termination network; Or initiate between the MGCF (Media Gateway Control Function abbreviates MGCF as) of the S-CSCF of network and the network that terminates; Or between the MGCF of the S-CSCF of termination network and initiation network; Or P service identification (P-Service-Identity, abbreviate PSI as) application server (Application Server, abbreviate AS as) pass through between the PSI and S-CSCF of query call conversation control function (Interrogating-CSCF abbreviates I-CSCF as) initiation.The type IOI can not transmit between heterogeneous networks, unless acted on behalf of MGCF and S-CSCF by borde gateway controlled function (Border Gateway ControlFunction abbreviates BGCF as) or I-CSCF.
The third IOI (Type 3IOI): be present between ownership S-CSCF and the AS; Exchange in the middle of request and response, IOI need send to AS.In the AS process, ownership S-CSCF produces Orig-IOI to ownership S-CSCF in preceding commentaries on classics message, and AS produces Term-IOI; When AS initiated request, AS produced Orig-IOI, and S-CSCF and I-CSCF produce Term-IOI.
The definition of above-mentioned three class IOI substantially can nerve of a covering between multiple operator identify mutually, the situation of expense sorting, wherein, the situation of IMS roaming that first kind IOI (that is Typel IOI) is corresponding.The charging data record of P-CSCF (Charging Data Record abbreviates CDR as) all needs to distinguish the different of accesses network and home network by the value of IOI with the CDR of S-CSCF, and carries out the IMS roam charge.But, Type1 IOI has only defined IOI in registration (Register) process, can be between the home network at the accesses network at P-CSCF place and S-CSCF place exchange message, clearly do not mention for SIP Invite (call request) process, therefore a lot of manufacturers are when exploitation, for SIP Invite process, the accesses network at P-CSCF place does not produce the Orig-IOI of the record access network information, and the home network at S-CSCF place does not produce the Term-IOI of record home network information yet.
Therefore, the user is after the accesses network registration that is different from its home network, and under the IMS roaming condition of make a call (Invite), in case registration finishes, P-CSCF and S-CSCF can not produce IOI, cause the IMS roam charge to have no basis.
