Embodiment

In order to more at large understand feature of the present invention and technology contents, below in conjunction with accompanying drawing, realization of the present invention is described in detail, the use of appended accompanying drawing explanation only for reference, is not used for limiting the present invention.

Fig. 1 is the structural representation of the non-roaming framework realizing GCS, as shown in Figure 1, the GCSAS in described application domain is provided by third party usually, and the GCSE that the part on the dotted line left side provides for 3GPP system, described GCSE comprises: local subscribed services device (HSS, HomeSubscriberServer), PCRF, mobile management entity (MME, MobilityManagementEntity), gateway (S-GW, ServingGateway)/P-GW, UE, Universal Terrestrial wireless access network (the E-UTRAN of evolution, evolveduniversalterrestrialradioaccessnetwork), broadcasting multicast service gateway (MBMS-GW), BM-SC, wherein, the mutual Interface realization by the corresponding model on connecting line between equipment between the said equipment,

Fig. 2 keeps successional realization flow schematic diagram for being switched to GCS when MBMS sends from unicast delivery; As shown in Figure 2, described method comprises:

Step 201: when carrying out session (OngoingGroupSession) in group as UE, when namely UE carries out group communication business, GCSAS is by GC1 interface notification UE;

Now, to send (MBMSDelivery) mode feasible and inform the Temporary Mobile Group Identity (TMGI, TemporaryMobileGroupIdentifier) of corresponding MBMS bearer service for MBMS;

Step 202:UE receives the clean culture downlink data (DLdataoverunicast) of GCSAS transmission by unicast delivery (UnicastDelivery) mode;

Step 203:UE detects and enters MBMS overlay area, and starts to receive data from MTCH, namely receives MBMS schedule information; TMGI on the corresponding Logical Traffic Channels (MTCH) of the data that described MBMS schedule information carries from MBMS;

Step: 204:UE receives the broadcast group broadcast downlink data (DLdataoverMBMS) of GCSAS transmission by the MBMS mode of sending;

Step: 205:UE receives the downlink data of GCSAS transmission simultaneously by clean culture and MBMS;

Step: 206:UE notifies that GCSAS stops sending unicast data stream (UEnotifiesGCSEAStostopsendingunicastflow);

Particularly, UE notify GCSAS oneself MBMS cover under and the MBMS bearer service that have received corresponding to TMGI, now, GCSAS stop send downlink data to UE by unicast delivery mode, subsequently, UE only receives the downlink data of GCSAS transmission by the MBMS mode of sending.

In the step of similar Fig. 2, when UE or network element detect that UE has shifted out MBMS coverage and can receive unicast delivery, in this handoff procedure, UE also can receive MBMS simultaneously and send the downlink data that mode and unicast delivery mode send, and then the downlink data that the interrupting receive MBMS mode of sending sends, receive only that unicast delivery mode sends downlink data, ensure the continuity of business during to be switched to Unicastdelivery from MBMSdelivery.

In the process that the above-mentioned mode of sending switches, GCSE will trigger charging message respectively and generates corresponding CDR, as: the core network element P-GW of EPC is the CDR that unicast delivery triggers that charging message generates P-GW, and the CDR of the network element BM-SC of MBMS to be the MBMS mode of sending trigger charging message generates BM-SC, but how the CDR that network elements (as: P-GW, BM-SC etc.) different in GCSE generates is done and not yet have clear and definite method for the charge associated of a GCS.

Here, there is outside charging identifier information (ExternalChargingIdentifier) in the CDR of described P-GW, and allow the network element in non-EPC that the charging identifier of generation is sent to P-GW; Concrete transfer mode can pass to PCRF by relevant information being comprised charging identifier etc. by third party AS (GCSAS can regard a kind of third party AS as) by Rx interface in policy control and charging (PCC) framework, then by Gx interface, information is passed to P-GW by PCRF.Such as, the schematic diagram of the PCC framework that 3GPP specification TS23.203 defines, as shown in Figure 3, described PCC framework comprises: signing attribute data storehouse (SPR, SubscriptionProfileRepository), application function (AF, ApplicationFunction), Online Charging System (OCS, OnlineChargingSystem), PCRF, bearing binding and event reporting function (BBERF, BearingBindingandEventReportFunction), flow detection function (TDF, TrafficDetectionFunction), strategy and charge execution function (PCEF, PolicyandChargingEnforcementFunction), off-line accounting system (OFCS, OfflineChargingSystem), gateway (Gateway), described gateway comprises P-GW, wherein, the mutual Interface realization by the corresponding model on connecting line between equipment between the said equipment, described PCC framework is that P-GW obtains outside charging identifier information from the network element (as third-party application server) non-EPC and provides solution, as shown in Figure 3, AF can be regarded as a kind of third-party application server (as: GCSAS etc.), strategy and PCRF receive the information from AF by Rx interface, wherein, described information comprises: outside charging identifier, third-party application supplier mark and third-party application mark etc., and described PCRF is passed through Gx interface by outside charging identifier, third-party application supplier mark and third-party application mark etc. pass to P-GW, so, outside charging identifier is just contained in the CDR of described P-GW, the information such as third-party application supplier mark and third-party application mark, but the network element in described MBMS does not produce any charging identifier information, do not obtain the charging identifier information of the network element in non-MBMS yet.Therefore, for a same GCS, ensure the continuity of GCS simultaneously, described P-GW is the CDR that generates of unicast delivery and described BM-SC is that the CDR that MBMS sends generation cannot do charge associated accordingly, thus cannot carry out effective charging and reconciliation to UE and/or third-party application server (AS).

Based on the problems referred to above, the invention process provides a kind of charging method, server and gateway, and to solve the problems of the technologies described above, concrete grammar is with reference to following embodiment.
