Description

Single user's charging method in multimedia broadcasting and the multicast service based on flow
Technical field
The present invention relates to a kind of in the WCDMA system for a multimedia broadcasting and a designed charging method of multicast service (hereinafter to be referred as MBMS), particularly for the charging method based on flow of unique user.
Background technology
MBMS is that third generation partner plan (3rd Generation Partner Project is hereinafter to be referred as 3GPP) proposes also carrying out a standardized new business.Corresponding standard is TR23.846, and its up-to-date version is 1.1.0.The MBMS business is a kind of business of unidirectional point-to-multipoint, and in this business, same piece of data can send to a plurality of terminal uses from a data source entity.This technology realizes by use common signal channel service data transmission on main body, so it can effectively utilize Radio Resource and Internet resources.The MBMS business has two kinds of patterns: broadcast mode (Broadcast mode) and multicast pattern (Multicast mode).
Fig. 1 has described the system configuration of MBMS, and the MBMS system configuration exchanges wireless traffic (hereinafter to be referred as GPRS) core net based on general packet.
In Fig. 1, UE105 is the user of MBMS business, and it can receive the MBMS data by WCDMA air interface Uu107.UTRAN104 is responsible for wireless access and allocation of radio resources in MBMS.SGSN103 provides some functions of MBMS access control, and the details of each UE all are arranged in SGSN, and promptly SGSN can directly control UE, so, collect in SGSN for the metering data of unique user.GGSN102 is a gateway of MBMS data source, and its function is that the MBMS data are sent in the target SGSN.BMSC101 is the data source of MBMS service, should collect at this for the charge information of content supplier.HLR106 is associated with SGSN, and its function is to differentiate and authorize the user (UE) of MBMS business.
In the gprs service field, billing mechanism need be collected each user's data flow information, can draw the detail of user's employed Internet resources in service conversation by this data traffic information, be used for the detailed data of each user based on charge on traffic for charge system (Billing System) provides.
Fig. 2 has described in existing gprs service in a service conversation downstream data flow quantitative statistics method for each UE.
UE201 sets up after the GPRS session, and when data process SGSN203, SGSN can monitor it to the data volume that this UE sent, and this data volume is called Vol1 (205) here.RNC202 can calculate the data volume that does not send to this UE by the corresponding mechanism of bottom, send comprising success and do not send and be retained in data volume in the RNC buffer area, this data volume is called Vol2 (in 204).So when this service conversation finished, the received downlink data amount of this UE was called Vol3 (in 206) in the data service session hereto, just can calculate by Vol1 and Vol2, i.e. Vol3=Vol1-Vol2.In this billing mechanism, since at be the type of service of point-to-point, so all descending data all mail to a UE in service conversation, so this UE the actual data volume that successfully receives just can obtain at network one end, need not participating in directly of user.About the detail of this billing mechanism can list of references 3GPP standard TS32.200 (up-to-date 4.1.0 version) and the standard TS32.215 (up-to-date 4.2.1 version) of document 3GPP.
Yet, in the standard of 36PP, go back the billing mechanism that neither one is directed to unique user and can be advantageously applied to a little in the business of multiple spot based on flow.Since (broadcast mode in the MBMS business is free for the user, also just need not to obtain the data traffic information of unique user, so the present invention is applicable to the multicast pattern of MBMS business.) prior art is applied to MBMS and mainly exists following problem maybe to need the place of improving:
1. in gprs service, RNC uses the mechanism (as replying and retransmission mechanism) of bottom to guarantee to obtain data volume that the success for each UE sends and buffer memory and the data volume that is not sent out.But in the MBMS business, business datum is public for all users, is not to be directed to certain user's.Even reply with retransmission mechanism and also do not advocate to use in the MBMS business, so if use common signal channel to send the MBMS data, RNC can't obtain the data volume that each UE is finally successfully received at all.So the billing mechanism based on flow in the existing gprs service is not suitable for the MBMS business.
2. existing another method be to use up signaling by UE periodically with its data volume that receives of success directly report and give SGSN, the data flow value that this up report comes just can be used for the charging based on flow of each UE, but still has two significant disadvantages:
A) on UTAN end and Iu interface, exist the serious congestion problem.In the MBMS business, have the possibility that a large amount of users uses simultaneously, each SGSN is managing a large amount of UE so, and each UE use up signaling report its data volume that receives of success, RNC is transmitted to SGSN with this up signaling.So many UE all need to report its data volume that receives of success, just necessarily have the simultaneous possibility of the up report of UE, this can cause the signaling congestion of UTRAN end and Iu interface undoubtedly.
B) signaling process that has increased the weight of SGSN is born.In a very short time period, a large amount of UE will be undertaken directly mutual with SGSN by up report signaling, these signalings must be handled at once by SGSN, so just will inevitably cause huge signaling process pressure, and cause it can not the better Business Processing that must satisfy other concurrent type to SGSN.
Summary of the invention
The objective of the invention is to provides a billing mechanism based on flow that is directed to unique user to the MBMS business, in a MBMS service conversation, collect unique user data traffic information and generate the required charge information of charge system.
In view of the billing mechanism based on flow in the gprs service model can't satisfy the MBMS point to this characteristic of multiple spot, we have adopted by UE oneself the statistics MBMS business datum amount that it successfully received, periodically this data on flows is upwards reported final this method of the SGSN of arrival by up signaling then, but two big shortcomings in view of aforesaid this method the present invention proposes one two phase data flow statistical method.This method is divided into two stages with the UE periodic data traffic report process that makes progress.In the phase I, the user with its data traffic that receives of success report to affiliated RNC, store this data by RNC.In second stage, when SGSN needs these data, initiatively ask for it to RNC.So just reduced the signaling process burden of the congested and SGSN of up signaling effectively.
For two phase data flow statistical methods are applied in the MBMS architecture, the present invention gives some necessary accessories and comes the method is provided support.In addition, the present invention gives detailed process, two stage data flux statistics method can be deployed in well among the MBMS business by these processes.
A kind of charging method based on flow that is directed to single user in the MBMS business of the present invention comprises that step is as follows:
(1) when user UE begins to receive the data of MBMS business, user UE oneself adds up its data traffic that successfully receives and periodically data traffic is reported message and issue RNC (305 under it, 306), after RNC receives that each UE data traffic of its subordinate is reported message, store the data traffic that is successfully received of each UE respectively, and can bring in constant renewal in described data traffic along with the periodic data traffic report of UE;
(2) when SGSN need close or inquire about the charging data record (MBMS-CDR) of a UE, SGSN initiatively sends the data traffic request message to the RNC that preserves described UE data traffic, RNC sends the data traffic response message after receiving described data traffic request message, the data traffic of the described UE that will preserve in the data traffic response message feeds back to SGSN, and SGSN generates a complete charging data record MBMS-CDR who is used for charge system according to the data traffic information of the described UE that is received.
In described step (2), if SGSN has the MBMS-CDR that closes a plurality of UE simultaneously, during the end of service of initiating as: core network end, just the demand signalling that SGSN sent so can ask to obtain the data traffic information of a plurality of UE.
RNC is provided with MBMS context (MBMS Context) for each UE, the MBMS context comprises " data traffic (Data Volume) " field that is used for storing the data flow value of described UE, when RAN receives that the data traffic of a UE is reported signaling, RAN just takes out relevant data from the described signaling that receives, find the MBMS context of this UE then, using foreign currency and notifying that data value upgrades data traffic (Data Volume) in the order " field; after RAN receives the data traffic demand signalling message that SGSN sends; RAN is from the contextual data traffic of the MBMSH of corresponding UE (Data Volume) " and reading out the data flow value the field, the data traffic of the described UE that will preserve in the response message of described data traffic demand signalling message feeds back to SGSN.
MBMS-CDR comprises: record type (Record Type) field, and can distinguish each charging data record (CDR) by described record type field charging gateway function body (CGF) is the type that belongs to any business; Charging mark (Charging ID) field, this field is the identifier of charging data record, its that can come together to identify among the SGSN uniquely and produced with the address of GGSN and all charging data record certain MBMS context dependent connection, described charging mark comprises two parts: first (401) is when first UE under the SGSN activates the MBMS business, give the value of this SGSN by GGSN, this value is unique in a GGSN territory, and the following first that activates the charging mark that all UE obtained of same MBMS business of SGSN is identical; Second portion (402) is produced by SGSN, and in a SGSN, it is unique getting final product that the generation of second portion only needs in the scope of the value of same first,
First and second portion combine resulting charging, and to be marked in the network of inherent all packet-switched domains of one quite long period be unique.Charging gateway function body (CGF) and charge system (Billing System) are used the address of GGSN and the uniqueness that described charging mark comes together to check the charging mark, if have uncertainty, add the timestamp that described charging data record is opened so.
In mobile management, after the MBMS of UE context was transferred among the new SGSN by old SGSN, the pairing charging mark of this MBMS context was also along with moving among the new SGSN.
The time interval that UE periodically reports the data traffic that it successfully received to RNC is produced by first clock among the UE.
The data traffic of being reported is an aggregate-value.Monitored the data traffic of UE by the second clock that is provided with for each UE at the RNC end and report message, after RNC received the data traffic report message of certain UE, the second clock of monitoring this UE just was reset at every turn; When the data traffic of UE is reported information drop-out, the second clock of the data traffic report message of this UE of monitoring is just expired after a period of time, RNC can determine that just this UE is under the abnormality, and for the consideration of chargeing, RNC notice SGSN finishes the MBMS business of this UE; If the data traffic of certain UE is reported information drop-out, before the second clock of monitoring is expired, RNC has received the next data traffic report message of this certain UE, the report message of losing can be ignored, the data flow value that data flow value that UE end is added up and RNC end are preserved synchronously, the MBMS business that RNC does not notify SGSN to finish this UE.
Data traffic is reported message and comprised: the UE sign is used for identifying the UE that sends this message; MBMS service identification (MBMS service ID) is used for identifying the related MBMS business of this message; The data traffic (Data Volume) of UE institute success reception when sending data traffic and reporting message.
Data traffic request (Data Volume Request) message mails to the data flow value that RNC is used for obtaining one or more UE from SGSN, described data traffic request (Data VolumeRequest) message comprises: the UE identification list, comprise one or more UE signs, indicate the data traffic which UE the data traffic request message seeks out; Reason for claim, then explanation sends the reason of data traffic request message; The MBMS service identification identifies employed MBMS business.
Data traffic is replied (Data Volume Response) message and is comprised MBMS service identification and data traffic tabulation, the MBMS service identification is used for identifying the related MBMS business of this message, data traffic tabulation (Data Volume List) identifies the data traffic set of the UE that the data traffic response message comprised, and the data traffic tabulation comprises UE sign and the pairing data traffic of this UE.
In addition, reason for claim in the event data stream amount request message is not the professional termination of MBMS, then RNC will send the UE of data traffic replacement (Data Volume Reset) message to appointment, the data flow value that is used for notifying UE to reset accumulative total is zero, after receiving this message, UE just restarts to add up the data traffic that it successfully receives, described data traffic replacement message comprises UE sign and MBMS service identification, the UE sign is used for identifying the UE that described data traffic replacement message is mail to, and the MBMS service identification is used for identifying the related MBMS business of described data traffic replacement message.
After a UE has activated selected MBMS business, in SGSN,, in SGSN, be accompanied by the contextual MBMS-CDR of this MBMS simultaneously according to charging characteristic brief introduction (ChargingCharacteristics Profile) generation just for this UE has produced a MBMS context.
In addition, under any situation that following four kinds of situations take place, cause the MBMS context of a UE in a SGSN, to delete:
The MBMS that UE initiates is professional to be stopped;
The MBMS that core net one end is initiated is professional to be stopped, and SGSN can obtain the data flow value of a plurality of UE simultaneously in a data traffic request message;
The second clock of reporting message by the monitoring UE data traffic among the RNC detects UE under abnormality;
The mobile switching of UE between SGSN.
Before the MBMS of UE context was about to delete in a SGSN, SGSN sent the data flow value that the data traffic request message obtains this UE (or other UE is arranged simultaneously), and SGSN closes the context-sensitive MBMS-CDR with this MBMS,
UE mobile between SGSN comprises two kinds of situations.First kind of situation is that UE is at routing region updating (Routing Area Update), the MBMS-CDR of the UE that is moved closes at old SGSN, new SGSN will send SGSN context request (SGSN Context Request) message to old SGSN, reply at the SGSN context of replying in (SGSN Context Response) message, the MBMS context of the UE correspondence that is moved and charging identifier are sent to the new SGSN from old SGSN, charging identifier does not change, the pairing MBMS-CDR of MBMS context of the UE that is moved produces in new SGSN, and the data flux statistics of the UE that is moved is started from scratch.Second kind of situation is mobile the comprise UE reorientation (Relocation) of UE between SGSN, the pairing MBMS-CDR of the UE that is moved closes in old SGSN, old SGSN hops re-positioning request (Forward Relocation Request) message to new SGSN with transmission, by the RELOCATION REQUEST message of hopping, MBMS context and charging identifier are sent among the new SGSN from old SGSN, charging identifier does not change, the corresponding new MBMS-CDR of the MBMS context of the UE that is moved produces in new SGSN, and the data flux statistics that is moved is started from scratch.
SGSN context request (SGSN Context Request) message comprises old P-TMSI, old RAI, old P-TMSI signature); The SGSN context is replied (SGSN Context Response) message and is comprised the MM context, PDP Context, MBMS context.
The relocation request message of hopping including IMS I, pipeline terminal point sign signaling, MM context, PDP Context, target identification, UTRAN transparent vessel, RANAP reason, MBMS context.
The effect of invention
1. by two phase data traffic statistics charging methods of the present invention, can obtain the data flow value of each UE actual reception in MBMS business, solved the problem of charging fairness in the business of putting multiple spot.
2. the billing mechanism among the present invention is flexibly.Send the clock of periodic data flow and the clock value that the RNC end is used for monitoring each UE periodic data flow report by regulating the UE end, can obtain different charging precision, satisfy the different charging requirement of operator.

Embodiment
Be not suitable for this defective of business that a little arrives multiple spot in order to overcome existing billing mechanism, and can improve the efficient that the upstream data flow is reported, the present invention has designed a billing mechanism that is used for the MBMS business, specifically comprises:
(1) two phase data flow statistical method
Fig. 3 has described two phase data flow statistical methods among the present invention
In this method, the report process of the data traffic that UE successfully receives is divided into two stages:
In the phase I 309, as UE (301,302,303, when 304) beginning to receive the data of MBMS business, UE oneself adds up its data traffic that successfully receives and periodically this flow is reported to the RNC under it (305,306), rather than directly reports to the SGSN in 307 under it.Each UE that RNC is responsible for its subordinate store its data volume that receives of success, and can report and bring in constant renewal in this data volume along with the periodic flow of UE, so just can guarantee RNC for data on flows that each UE preserved and each UE reality the data traffic maintenance of success reception synchronous.In addition, RNC also is responsible for the abnormality of UE is made instant reaction and corresponding the processing.
In second stage 310, before each charging data record (hereinafter to be referred as MBMS-CDR) of certain UE is closed, SGSN needs the data traffic information of this UE that the phase I preserves and generates a complete MBMS-CDR who is used for charge system, at this moment, SGSN initiatively sends request to the RNC of this UE data traffic information of preservation, after RNC receives this demand signalling, in response message, give SGSN, so just reduced the signaling process burden of the congested and SGSN of Iu interface the data traffic feedback information of required UE.In addition, if the MBMS-CDR that a plurality of UE are arranged will close when end of service (as: core network end initiate) simultaneously, demand signalling that SGSN sent just can ask to obtain the data traffic information of a plurality of UE so, can further reduce the signaling process burden of the congested and SGSN of Iu interface like this.
(2) the MBMS context of in RNC, depositing (MBMS Context) for each UE
Since all UE of RNC subordinate all need with its data traffic that receives of success report to this RNC, so, in order to store this data traffic, advocate among the present invention in RNC, to comprise with each UE relevant MBMS context, wherein need " Data Volume " field be used for storing this UE the data traffic that receives of success, other field is not defined among the present invention.Each when RNC receives that the data traffic of a UE is reported signaling, from then on RNC just takes out relevant data in the signaling, finds the MBMS context of this UE then, using foreign currency data flow value renewal " Data Volume " field in the order of notifying.
In above-mentioned second stage, when SGSN inquires about the data flow value of a UE, SGSN sends out the data traffic request message and gives UE affiliated RNC, take out the data flow value in RNC " Data Volume " field from the MBMS context of this UE, in the response message of this data traffic demand signalling message, feed back to SGSN.
(3) be used for two kinds of clocks that the periodic data flow is reported
In the present invention, reporting for the data traffic of property performance period need two kinds of clock.
At the UE end, UE periodically reports the data traffic that it successfully received to RNC, and this is a first kind clock.When billing mechanism is started working, the parameter of this clock is set and has started clock by signaling message, this clock just can trigger the periodic data traffic of UE and report message.
The data flow value that UE periodically reports is an aggregate-value, and this value has added up the data traffic that UE successfully received.After each MBMS-CDR of this UE closes, and when generating a new MBMS-CDR, then by the signaling message notice UE cumulative data flow value again of starting from scratch.
At the RNC end, for each UE is provided with another clock.This clock is used for monitoring the data traffic report message of UE, and after RNC received the data traffic report message of certain UE, the monitoring clock of this UE just was reset at every turn.When the data traffic of UE is reported information drop-out (as: UE is under the abnormal condition), it is just expired that the data traffic of this UE is reported the message monitoring clock after a period of time, RNC can determine that just this UE is under the abnormality, for the consideration of chargeing, the MBMS business that can notify SGSN to finish this UE.If the data traffic of UE is reported information drop-out, before monitoring clock is expired, RNC has received the next data traffic report message of this UE, because the data traffic of reporting in the message is an aggregate-value, so the report message of losing can be ignored, this do not influence data flow value that data flow value that UE end added up and RNC end preserve synchronously, this is the reason that the present invention adopts accumulated value to report.
When a UE changes abnormality over to by normal condition, the data flow value after so last the report just can not reported the RNC place, causes the inaccurate of charging.So if the value of these two kinds of clocks is provided with more for a short time, the value of resulting data traffic is just accurate more.But clock setting must be more little, and the generation of signaling and processing are just frequent more, caused the operation burden of network.Thus, operator can be provided with the value of these two kinds of clocks as required in order to obtain different charging precision, so just can strengthen the flexibility of chargeing.
It is big that the value that is used for the clock that monitoring data traffic reports among the RNC should be reported the value of clock of message than UE triggering for generating data traffic.
(4) content of MBMS-CDR
In the present invention, the content of the S-CDR in the most contents of MBMS-CDR and the gprs service is identical, is that following two clauses and subclauses need be changed:
A) record type (Record Type):
This field can identify the type of charging data record (CDR), can distinguish each charging data record (CDR) by this field charging gateway function body (CGF) and belong to any business.So here the value of these clauses and subclauses should be MBMS-CDR, mark this charging data record and generate for MBSM is professional.
B) charging mark (Charging ID):
This field is the identifier of charging data record, all charging data record that are associated with certain MBMS context (being directed to single UE's) that it can come together to identify among the SGSN uniquely and produced with the address of GGSN.In the billing mechanism of gprs service, when being marked at PDP context activation (activation of service), charging produces by GGSN, pass to the mark of SGSN then, can guarantee that like this it is unique in this GGSN territory as the charging data record that PDP Context is relevant therewith.But in the MBMS business, have only among the SGSN first UE that activates service could be mutual with GGSN, the UE that adds subsequently of this service be not mutual with GGSN.So in the present invention, the task of generating the charging mark is born by SGSN.It is unique that this charging that just needs an algorithm to guarantee that SGSN generates is marked in the whole GGSN territory.Provided a mechanism in the present invention and guaranteed that it is unique being marked in the GGSN territory by the charging that SGSN produces.As shown in Figure 4, this charging mark comprises two parts.
401 firsts are when first UE under the SGSN activates the MBMS business, give the value of this SGSN by GGSN, this value is unique in a GGSN territory, so the following first that activates the charging mark that UE obtained of same MBMS business of SGSN is identical.That is: GGSN is that a SGSN has distributed the charging mark of set of number as a MBMS business among this SGSN.
402 second portions are produced by SGSN, second portion depends on first, so in a SGSN, it is unique getting final product that the generation of second portion only needs in the scope of the value of same first, that is to say, for the value of different firsts (that is: different business), second portion can be identical, can effectively utilize the value of second portion like this in a SGSN.And in a business, if a UE activating service and releasing business in same SGSN, this UE employed second portion value in this business can be reused for the value of its used first.Entire first portion and second portion combine resulting charging, and to be marked in the network of inherent all packet-switched domains of one quite long period should be unique.And in mobile management, after the MBMS of UE context was transferred among the new SGSN by old SGSN, the pairing charging mark of this MBMS context was also along with moving among the new SGSN.Charging gateway function body (CGF) and charge system (Billing System) are used the address of GGSN and the uniqueness (seeing reference 2) that the charging mark comes together to check the charging mark, if still have uncertainty, so at the timestamp that adds that this charging data record is opened.
(5) the periodic data flow is reported process
Fig. 5 has described periodic data flow report process in the two phase data flow reporting mechanisms.
510 is the phase I in the two phase data flow reporting mechanisms
501 work as UE begins data flow quantity statistical and has spent one period regular time (UE end trigger data flow is reported the clock value of message), and UE should initiate a data traffic and report.
502 UE send data traffic and report (Data Volume Report) message (UE sign, MBMS service identification, data traffic) to RNC.
RNC under this message is sent to by UE is used for periodically reporting the data flow value that it successfully receives.By this message, the data flow value of an accumulative total mails to RNC, and each RNC receives this message, just uses data flow value wherein to upgrade the data flow value that is kept at this UE among the RNC.Wherein, UE sign (UE id) is used for identifying the UE that sends this message, MBMS service identification (MBMS service ID) is used for identifying the related MBMS business of this message, and data traffic (Data Volume) is the data traffic of UE institute success reception when sending this message.
503 RNC upgrade this UE data traffic value field in the MBMS context in RNC with the new data flow value in this message after receiving that data traffic is reported message.
504 RNC reset and wherein monitor the clock that this UE data traffic is reported message.
505 501 to 504 processes periodically repeat.
511 is the second stage in the two phase data flow reporting mechanisms
506 MBMS-CDR that detect this UE (UE that perhaps other is arranged simultaneously) as SGSN are about to close, and are that SGSN is when collecting the data flow value of this UE (perhaps other UE is arranged simultaneously).
507 SGSN send data traffic request (Data Volume Request) message (UE identification list, reason for claim, MBMS service identification) and obtain its data flow value to the RNC under this UE.
This message mails to the data flow value that RNC is used for obtaining one or more UE from SGSN.This message occurs in before MBMS-CDR that one or more UE are associated will close in SGSN.The UE that this message is concerned about is those UE that the UE sign is identified in the UE tabulation in the message.UE identification list (UE id List) parameter comprises one or more UE signs, indicates the data traffic which UE is this message seek out.The employed MBMS business of MBMS service identification (MBMS Service id) parameter identification.Reason for claim (Request Reason) parameter has then illustrated the reason that sends this message, i.e. the MBMS-CDR of this UE reason of closing (MBMS professional stop and other closes reason).
508 after RNC receives the data traffic request message of SGSN, and RNC sends data traffic and replys (Data Volume Response) message (MBMS service identification, data traffic tabulation) to the SGSN that is asked.
This message is the response message of data traffic request message, mails to SGSN by RNC.By this message, RNC can send to the data flow value of request UE (one or more) SGSN that initiates the data traffic request message.Wherein, data traffic tabulation (Data Volume List) parameter identification goes out the data traffic set of the UE that this message comprises, comprises UE sign (UE in the tabulation
Id) and the pairing data traffic of this UE (Data volume).MBMS service identification (MBMSservice id) parameter is used for identifying the related MBMS business of this message.
Stop if the reason for claim in 509 507 steps in the data traffic request message is not the MBMS business, then RNC will send the UE of data traffic replacement (Data Volume Reset) message (UE sign, MBMS service identification) to appointment.
It is zero that this message sends to the data flow value that UE is used for notifying UE to reset accumulative total by RNC, and after receiving this message, UE just restarts to add up the data traffic that it successfully receives.Wherein, UE sign (UE id) parameter is used for identifying the UE that this message mails to, and MBMS service identification (MBMS service ID) parameter is used for identifying the related MBMS business of this message.
(6) production process of MBMS-CDR
In order to be provided in MBMS business for the unique user needed information of chargeing, SGSN should provide a charging data record (CDR), wherein comprises the charge information that SGSN has obtained.In the present invention, this charging data record called after MBMS-CDR.Fig. 6 has described the production process of MBMS-CDR.
601 is examples that UE activates the process of MBMS business, but the present invention is not limited thereto specific MBMS activation of service process, any MBMS activation of service process all is applicable to the present invention.
602 after a UE has activated selected MBMS business, just for this UE has produced a MBMS context, simultaneously, is accompanied by the contextual MBMS-CDR of this MBMS and also produces in this SGSN among the SGSN.The generation of MBMS-CDR is according to the data in the charging characteristic brief introduction (ChargingCharacteristics Profile).
(7) beginning of data flux statistics
Fig. 7 has described the zero hour and the process of a UE data flux statistics
701,702,703 and 704 is that business datum arrives, and the service request of notify UE and having obtained UE has been created the overall process of RAB and RB afterwards, and the present invention is not limited to the process of setting up of specific RAB and RB.
705 after RAB and RB have set up, and each UE begins to add up own data flow value that successfully is received and the clock that sets regular report data flow value, and simultaneously, RNC is provided with the data traffic report message that clock begins to monitor affiliated UE for each UE.
706 MBMS business datums mail to UE.
(8) termination of data flux statistics in a SGSN
Before the MBMS of UE context was about to delete in a SGSN, SGSN should close the context-sensitive MBMS-CDR with this MBMS.So SGSN just sends the data traffic request message and collects the data flow value that this UE receives, the RNC under this UE replys for the request of SGSN, has comprised the data flow value of this UE in this response message.There are four kinds of situations can cause the MBMS context of a UE will in a SGSN, delete (Fig. 8), as:
The MBMS that 801 UE initiate is professional to be stopped.
The MBMS that 802 core net, one end is initiated is professional to be stopped.In this case, SGSN can obtain the data flow value of a plurality of UE simultaneously in a data traffic request message.
803 UE are under abnormality, and this situation can arrive by the clock detection of the report of the monitoring UE data traffic among RNC message.
The mobile switching of 804 UE between SGSN.
If above any situation (801,802,803,804) takes place, below two processes will carry out:
805 SGSN send the data flow value that the data traffic request message obtains this UE (or other UE is arranged simultaneously).
The MBMS-CDR of 806 these UE closes in this SGSN.
(9) UE moving between SGSN
In the present invention, UE mobile between SGSN have two kinds of situations with charge relevant:
* UE is in routing region updating (Routing Area Update) process.The MBMS-CDR of this UE closes at old SGSN, new SGSN will send SGSN context request (SGSNContext Request) message (old P-TMSI, old RAI, old P-TMSI signature) to old SGSN, reply (SGSN Context Response) message (MM context at the SGSN context of replying, PDP Context, the MBMS context) in, the MBMS context of this UE correspondence and charging identifier are sent to the new SGSN from old SGSN, charging identifier does not change, the pairing MBMS-CDR of MBMS context of this UE produces in new SGSN, and the data flux statistics of this UE is started from scratch.
* UE is in reorientation (Relocation) process.The pairing MBMS-CDR of this UE closes in old SGSN, old SGSN is with transmission re-positioning request (ForwardRelocation Request) message (IMSI that hops, pipeline terminal point sign signaling, the MM context, PDP Context, target identification, the UTRAN transparent vessel, RANAP reason, MBMS context) message is given new SGSN, by this message, MBMS context and charging identifier are sent among the new SGSN from old SGSN, charging identifier does not change, and the corresponding new MBMS-CDR of the MBMS context of this UE produces in new SGSN, and the data flux statistics of this UE is started from scratch.
(10) UE is in the detection and the processing of abnormality
When a UE occurred entering abnormality unusually, RNC just can not receive the periodic data traffic report message of this UE, and for the consideration of chargeing, this MBMS business of this UE should stop, and Fig. 9 has described the process that UE is in abnormality that detects.
901 when UE is in abnormality, and the periodic data traffic of this UE is reported message just can not arrive the affiliated RNC of this UE.
902 have spent a period of time, and it is expired to be used for detecting the clock that this UE periodic data flow reports among the RNC, and RNC can judge that just this UE has occurred unusually.
903 RNC just initiate to remove MBMS context request (Deactivate MBMS ContextRequest) message stops this UE to SGSN this MBMS business.
904 SGSN receive and remove after the MBMS context request message, carry out the MBMS business that corresponding process stops this UE.The process that SGSN stops the MBMS business of certain UE does not belong to the present invention.
