Embodiment
Fig. 2 has simply described the process of card.BM-SC is before the data that send a certain MBMS business, a period of time sends the MBMS card in advance, the purpose of card is that correlation circumstance with a certain MBMS business is (as traffic flag, the professional time started etc.) tell UE, so that UE can receive under the situation of card, add and use a MBMS business.Be noted that in the prior art, can be before the distance actual service begins very long a period of time of card take place (as business begin a few days ago or several week), the card process can repeatedly repeat, up to the MBMS of its advertisement service ending.
Above-mentioned Fig. 2 201 in, the business contexts among the BM-SC disposed by operation and maintenance function before a certain professional beginning.Before business began, the business contexts among the BM-SC mainly comprised parameter:
The a certain MBMS business of the unique sign of traffic flag (as IP multicast address).The business datum of MBMS is to be organized into once or the form of continuous several times session sends, a session can comprise that the one or many data send, MBMS is when sending the data of a certain MBMS business, it can be organized into one or continuous a plurality of session, so time of having indicated one of a certain MBMS business or continuous a plurality of session to begin professional time started.Each session time started apart from this session for the first time the data transmitting time can be very short even do not have, from the viewpoint of measures of UE, the session time started almost is exactly the time that data send.Allow the adding time started to represent that UE can begin to add the time of this MBMS business, this time should begin in a period of time before the professional time started.There is description the back that acts on of segment reference value.
Above-mentioned Fig. 2 202 in, BM-SC is the parameter traffic flag, the professional time started, allow to add the time started, and the segment reference value sends in card message, in advertisement process, BM-SC can send repeatedly card message.For some MBMS business, BM-SC can be before business begins a very long time (as several days even several week) beginning card process.For certain MBMS business, allow the adding time started can be set at several hrs or dozens of minutes before the professional time started, this can rule of thumb be worth setting by network side, so that there is time enough to handle the access request of all UE that use this MBMS business.Need to prove that the N/W among Fig. 2 represents that BM-SC sends node such as GGSN that card message need be passed through, SGSN, RNC or CBC, step 2 couple some MBMS are professional in addition can repeatedly repeat, and finishes up to professional transmission of this MBMS.
For a certain reason, though received card message as certain UE, but owing to the reason of signal quality has been resolved permission adding time started parameter wherein mistakenly, so certain UE may just initiate to add the process of MBMS business before allowing to add the time started.If network had just been received the request that adds this MBMS business before the permission of certain MBMS business adds the time started, then network should be refused this request.The method of the false request of network refusal UE has two kinds, and first method is the reason of notifying UE to make mistakes, and permission that will be correct adding time started parameter tells UE once more, so in first method, network need feed back to UE, this method as shown in Figure 3; Second method is to reduce the work of network side, so in the second approach, network responds the false request of UE, and when UE sends several times request message and after the feedback, UE thinks automatically and add failure that this method as shown in Figure 4.
Above-mentioned Fig. 3 301 in, UE sends IGMP message (this message comprises IP multicast address) to GGSN and requires to add a certain MBMS business.
Above-mentioned Fig. 3 302 in, GGSN sends the MBMS authentication request message to BM-SC after receiving the IGMP message that UE in above-mentioned 301 sends, this message comprises parameter: IP multicast address.
Above-mentioned Fig. 3 303 in, after BM-SC receives the MBMS authentication request message that GGSN sends in above-mentioned 302, BM-SC checks the IP multicast address that comprises in this message, if BM-SC checks the back and finds legal MBMS business of this IP multicast address sign, BM-SC sends MBMS authentication responses message to GGSN, this message comprises parameter: Cause (reason), the value of Cause is successfully simultaneously.
Above-mentioned Fig. 3 304 in, GGSN and SGSN and UE are mutual, require UE to initiate to set up the contextual process of MBMS, then UE initiates to set up the contextual process of MBMS, process in 304 is existing process, repeats no more, and this process comprises several message, and the last item message is that request message set up in the MBMS context that SGSN issues GGSN, and this message comprises about the parameter of this MBMS business and the sign of UE.
Above-mentioned Fig. 3 305 in, GGSN sends MBMS to BM-SC and inserts request message, this message comprises parameter: IP multicast address, APN, and UE sign.
Above-mentioned Fig. 3 306 in, after BM-SC received the message that GGSN in 305 sends, BM-SC checked UE sign and IP multicast address and APN.If by checking IP multicast address and APN, BM-SC thinks that this is the legal MBMS business of an existence, BM-SC continue to check that the permission of this MBMS business adds the time started: if when BM-SC receives the message that GGSN sends in 305, allow to add also not arrival of time started, then BM-SC sends MBMS to GGSN and inserts response message, this message comprises parameter " Cause " (reason of success or failure and failure) and " allow add time started ", herein Cause represent to fail and fail former because " allowing to add the time started no show "; When if BM-SC receives the message that GGSN sends in 305, allow the adding time started to arrive, then BM-SC sends MBMS to GGSN and inserts response message, and this message comprises parameters C ause, and Cause represents success herein.
Above-mentioned Fig. 3 307 in, after GGSN receives the message that BM-SC sends in 306: if parameters C ause wherein represents success, GGSN sets up about the MBMS context of UE and to the SGSN transmission and sets up the MBMS context acknowledge message, and this message comprises parameters C ause, and Cause represents success herein; If parameters C ause wherein represents failure, then GGSN does not set up the MBMS context, and send to SGSN according to the parameter in the message of receiving and to set up the MBMS context acknowledge message, this message comprises parameters C ause and allow to add the time started, herein Cause represent to fail and fail former because " allowing to add the time started no show ".
Above-mentioned Fig. 3 308 in, after SGSN receives the message that GGSN sends in 307: if parameters C ause wherein represents success, SGSN sets up about the MBMS context of UE and sends the MBMS context to UE and sets up response message, and this message comprises parameters C ause, and Cause represents success herein; If parameters C ause wherein represents failure, then SGSN does not set up the MBMS context, and send the MBMS context according to the parameter in the message of receiving to UE and set up response message, this message comprises parameters C ause and allow to add the time started, herein Cause represent to fail and fail former because " allowing to add the time started no show ".After UE received that response message set up in the MBMS context of SGSN transmission: if parameters C ause wherein represents success, UE activated the MBMS context of oneself; If what parameters C ause wherein represented to fail and fail is former because " allowing to add the time started no show ", UE preserves " allowing the to add the time started " parameter in this message, and no longer sends the message that adds this MBMS before allowing to add the time started arrival.
Above-mentioned Fig. 4 401 in, UE sends IGMP message (this message comprises IP multicast address) to GGSN and requires to add a certain MBMS business.
Above-mentioned Fig. 4 402 in, GGSN sends the MBMS authentication request message to BM-SC after receiving the IGMP message that UE in above-mentioned 401 sends, this message comprises parameter: IP multicast address.
Above-mentioned Fig. 4 403 in, after BM-SC received the message that GGSN in 402 sends, BM-SC checked IP multicast address.If by checking IP multicast address, BM-SC thinks that this is the legal MBMS business of an existence, BM-SC continue to check that the permission of this MBMS business adds the time started: if when BM-SC receives the message that GGSN sends in 402, allow to add also not arrival of time started, then BM-SC sends MBMS to GGSN and inserts response message, this message comprises parameter " Cause " (reason of success or failure and failure) and " allow add time started ", herein Cause represent to fail and fail former because " allowing to add the time started no show "; When if BM-SC receives the message that GGSN sends in 402, allow the adding time started to arrive, then BM-SC sends MBMS to GGSN and inserts response message, and this message comprises parameters C ause, and Cause represents success herein.
Above-mentioned Fig. 4 404 in, after GGSN receives that MBMS that BM-SC in 403 sends inserts response message: if the parameters C ause in this message represents success, 405 process below then GGSN continues; If the parameters C ause in this message represents failure, then GGSN preserves the permission adding time started parameter in this message, so that receive once more when requiring to add the IGMP message of this MBMS business, GGSN can be according to allowing the adding time started to judge whether to send out the access request message to BM-SC again, the action of GGSN stops then, does not enter into for 405 stages.
Above-mentioned Fig. 4 405 in, GGSN and SGSN and UE are mutual, finish foundation together about the contextual process of the MBMS of UE, this is existing process, repeats no more.It should be noted that, if in above-mentioned 404, GGSN is owing to receive the message that BM-SC sends in 403 and find that parameters C ause wherein represents failure, then GGSN did not enter into for 405 stages, caused 405 processes not take place like this, so UE is after the IGMP message that sends in 401, can not obtain any feedback, at this moment UE may send IGMP message several times once more, and after can not get further feedback, UE can initiatively abandon adding this MBMS business in this time.
Fig. 5 is example card process time started of having represented this MBMS business, allows to add the relation between time started and professional time started with a MBMS business.Be example with June among Fig. 5, the card time started is 8:00AM on June 10, the a certain MBMS of indication is professional in the card can provide at 8:00PM on June 15 (promptly the professional time started is 8:00PM on June 15), allow adding the time started is designated as 8:00AM on June 15, and all UE that will receive this MBMS business should initiate the process of this MBMS business of adding June 15 after the 8:00AM so.Allow adding the time started can be expressed as a concrete time, is 8:00AM on June 15 as the example of Fig. 5; Perhaps be expressed as a relative time with respect to the professional time started, as above then it allows to add time started and also can be expressed as 12 hours shown in the illustration 5, also promptly allows to add than the professional time started Zao 12 hours time started.
In above-mentioned Fig. 5, when allow to add the time started in card by advertisement after, the UE that this advertising message of uppick and wishing receives this MBMS business can allow to add after time started arrives at it, initiates to add the process of MBMS business.A problem of thereupon bringing is, allowing to add time started very short a period of time after arriving, may have a large amount of UE and require to add this MBMS business simultaneously, thereby cause congested on the air interface.Among the present invention this problem of newly bringing is had further prioritization scheme, method is as follows:
1. network terminal will allow to add the moment that is carved into professional beginning when the time started begins and be divided into n (n is a natural number) the individual time period, to be example among Fig. 5, then will be divided into n time period in 12 hours, n=12 for example, and then each time period is one hour.In card, n is sent with the permission adding time started as parameter (is the segment reference value hereinafter to be referred as this parameter) then.
2. each UE that receives card calculates oneself by parameter (promptly allowing to add time started and segment reference value n) wherein and should go the real process of initiating to add the MBMS business in which time period.For example, UE can (be IMSI with the UE sign of oneself, and IMSI is the integer greater than 0) remove and get its remainder k then with n, be IMSI mod n=k, initiate to add the time started of MBMS business procedure with this remainder k as oneself then, here obvious 0≤k≤n is k time period so UE can initiate to add the time of MBMS business.Still be example with Fig. 5, if n=12, then allow adding time started to the professional time started to be divided into 12 time periods, 1 hour each time period, the IMSI that supposes certain UE is 324567,324567 mod 12=3 then, so this UE should initiate to add the process of MBMS business the 3rd time period, promptly this UE should initiate the process of adding MBMS business on 15th after the 10:00AM.Need to prove, (as the firm opening power of UE) for some reason, certain UE may be after the permission adding time started begins, just receive card message, in this case, if the time period that this UE calculates is over and done with, this UE can initiate to add the process of MBMS business in the current time period.In addition, network is after the request of the adding MBMS business of receiving UE, only need as the process of Fig. 3 or Fig. 4, whether the permission adding time started of judging this MBMS business arrives, and should not judge further whether this UE is the MBMS request of initiating in the time period that belongs to it, because the purpose of the method for this further optimization is just for fear of congested in the air.
