Description

The sending method of multicast service data, Apparatus and system
Technical field
The present invention relates to communication technical field, relate in particular to sending method, the Apparatus and system of a kind of multicast (MBMS, Multimedia Broadcast/Multicast Service) business datum.
Background technology
In the communication system like WCDMA, there are three kinds in channelling mode: logic channel, transmission channel and physical channel.Wherein, transmission channel is used for physical layer provides service to high level, transmits the load mode of this channel institute loaded information, depends on physical channel; Physical channel is used for the needs information transmitted is sent.Physical channel can be divided into DPCH (DPCH) and public physic channel such as Your Majesty physical channel (PCCPCH), auxilliary public physic channel (SCCPCH) or the like altogether.
On down direction, radio network controller (RNC) sends to base station (NodeB) with the business datum that receives through FACH or the like transmission channel; The base station sends to subscriber equipment (UE) with business datum through air interface through physical channel again.
The transmission time of data in channel is time of day with the frame, and correspondingly, the channel that is used to transmit data can be divided into four layers in time: system-frame, radio frames, subframe, time slot or chip.Usually, the frame length of system-frame is 720ms, comprises 72 radio frames; A radio frames comprises 38400 chips.One sub-frame is that a radio frames is divided into the portion in many parts.During the actual transmissions data, Transmission Time Interval (TTi) is the integral multiple of the frame length of a radio frames normally, and under the data in high speed transmission environment, TTi gets the frame length of a sub-frame.The data of whenever sending at a distance from a frame duration are a Frame, and the frame number of Frame can be represented the transmission time of this Frame, and the Frame less like frame number sends the back transmission that frame number is bigger earlier.The value number of frame number is between initial frame number and preset maximum frame number, and the frame number of a frame is an initial frame number, and is every afterwards at a distance from a frame duration; The frame number of Frame adds one; Tail frame frame number is maximum frame number, afterwards, begins from initial frame number again; The Frame frame number that mark is later is until DTD.
Transmit with form of data frames based on data, correspondingly, the elapsed time clock on node such as RNC and base station and the channel also is time of day with the frame.For node, when beginning to transmit data, this nodal clock picks up counting corresponding to initial frame number.For channel, when channel was established, the initial frame number of this channel clock promptly was assigned with.Because each clock is not to be synchronous, and possibly to adopt different frames be time of day, therefore, needs each clock of difference.Note is that the frame number of timing benchmark is RNC frame number (RFN) with the clock of RNC.Note is that the frame number of timing benchmark is base station frame number (BFN) with the clock of base station.Transmission data demand clock synchronization between base station and UE.The clock of safeguarding oneself is removed in the base station, also will safeguard the clock of a plurality of sub-districts under this base station.The base station need and UE between carry out clock alignment, this is aligned in UE and gets into before the wireless connections, the clock of the PCCPCH that sets up with sub-district on the base station is the timing benchmark, corresponding timing frame number is the System Frame Number (SFN) of this sub-district.The base station is through broadcast channel broadcasts SFN, and after UE inserted wireless connections, UE adjusted the clock of oneself and the clock synchronization of corresponding district based on the SFN that receives.During based on FACH channel of setting up or HS-DSCH channel transmission data, the frame number of Frame is the timing benchmark with the clock of FACH channel or HS-DSCH channel, is designated as Connection Frame Number (CFN) between UE and base station.Because the possibility of the clock on each node and each channel life period deviation, therefore, to same Frame, the frame number that provides separately maybe be different.
3GPP proposes the HSPA+ evolution network framework on the basis of existing R6 version, the main feature of this HSPA+ evolution network framework is: the UTRAN flattening, the function that is about to RNC is compressed on the NodeB+, and NodeB+ only supports PS professional.The MBMS business is one of important content of 3GPP business development.MBMS requires a plurality of NodeB+ of network side can identical MBMS synchronizing traffic data be sent to a plurality of UE based on the HSPA+ network architecture, to save air interface resource.
3GPP points out, should go up eat dishes without rice or wine merging or soft folding to business datum based on user side UE, realizes that MBMS is professional.What is called eats dishes without rice or wine to merge or soft merging is meant, for a MBMS business datum, each NodeB+ of different districts should be able to adopt identical coded system, and the signal that will carry this MBMS business datum simultaneously sends to a plurality of UE through eating dishes without rice or wine.Like this, after each UE receives the same signal from a plurality of NodeB+, can be with the different multipath components of a plurality of identical signals as same signal, realize of the merging of a plurality of identical signals in physical layer.Therefore, the MBMS business realization can promote the reception that UE receives MBMS business datum coherent signal, correspondingly improves user satisfaction.And based on eat dishes without rice or wine merging and the soft merging of UE, a plurality of NodeB+ adopt identical time-frequency domain transfer resource, and identical MBMS business datum is sent to a plurality of UE, thereby save interface-free resources.
Referring to Fig. 1, Fig. 1 is the configuration diagram of MBMS service synchronization among the HSPA+.Comprise two kinds of NodeB+ that are in the heterogeneous networks status in the framework shown in Figure 1, a kind of is main NodeB+, and a kind of is from NodeB+; Main NodeB+ receives the MBMS business data packet that SGSN issues, after MBMS business data packet encapsulation framing, be distributed to through the Iur interface connected each from NodeB+; Afterwards; Again by respectively merging or soft merging based on eating dishes without rice or wine on the UE from NodeB+, with the MBMS business data frame of encapsulation again through and UE between transmission channel, send to UE.
Referring to Fig. 2, Fig. 2 is the another kind of configuration diagram of MBMS service synchronization among the HSPA+.Wherein, being provided with two main NodeB+, is respectively main NodeB+1 and main NodeB+2, and each main NodeB+ has separately a plurality of from NodeB+.In the network architecture shown in Figure 2, be provided with ip router 1 between SGSN and each the main NodeB+, based on ip router 1, SGSN sends to each main NodeB with the MBMS business data packet.Between each main NodeB+ based on the Iur interface communication.Each main NodeB+ and its are provided with ip router between the NodeB+, and based on the IP multicasting technology, each main NodeB+ will add corresponding IP multicast address after will receiving that packet that SNSG issues is through corresponding the processing, send to corresponding ip router.After each ip router is received the packet that carries IP multicast address, in the IP multicast group that packet is sent in correspondence from NodeB+, afterwards, again by respectively synchronously the MBMS business datum of carrying this MBMS business data packet being sent from NodeB+.
Since main NodeB+ go up with the clock from the NodeB+ respectively maybe the life period deviation; Therefore; Make the merging of eating dishes without rice or wine on the UE be difficult to realize with soft merging; That is to say that for the frame number CFN that respectively goes up packaged MBMS business data frame from NodeB+ that carries the same MBMS service data bag, the absolute time that is indicated is also inequality.So-called absolute time is meant that with the initial timing point on the time shaft on the space-time concept(ion) be the time of reference point timing.
Need to prove; Eat dishes without rice or wine to merge the soft merging of comparing; The synchronous requirement of a plurality of NodeB+ being sent same MBMS service data is strict more; Eat dishes without rice or wine to merge and require certain NodeB+ to send time of MBMS business datum, and the time deviation that other NodeB+ sent between time of same MBMS service datas is no more than tens chips, soft merging then requires this time deviation to be no more than a TTI and a time slot sum.
In addition, referring to Fig. 3, Fig. 3 is existing RNC sends the FACH Frame to NodeB+ through the FACH channel a schematic flow sheet.Referring to Fig. 4, Fig. 4 is the structural representation of FACH Frame.Each FACH Frame comprises FP packet header (Header) and load (Payload) two parts, and the detailed description of relevant FACH Frame can not specifically describe among the application referring to related data.
Required being noted that; NodeB+ receives after the FACH Frame of RNC transmission; A plurality of data cells (MAC-c/sh SDUs) of carrying according to Payload wherein; And the priority of these MAC-c/sh SDUs of Header indication is identical, according to the sequencing that each MAC-c/sh SDUs occurs in the FACH Frame, is eating dishes without rice or wine to send each MAC-c/sh SDUs successively.Therefore, if in the HSPA+ framework, main NodeB+ is based on this FACH data frame structure, to sending the MBMS business data packet from NodeB+, then is difficult to satisfy and eats dishes without rice or wine on the UE to merge or the requirement of soft merging.
Referring to Fig. 5, Fig. 5 is that existing RNC is through the schematic flow sheet of HS-DSCH channel to NodeB transmission HS-DSCH Frame.Shown in Fig. 6 a and Fig. 6 b two kinds of structural representations of HS-DSCH Frame.The detailed description of relevant HS-DSCH Frame can also no longer specifically describe among the application referring to related data.Required being noted that after NodeB receives the HS-DSCH Frame that RNC sends, to the scheduling situation of each MAC-c/d SDU wherein, confirmed the transmitting time of each MAC-c/d SDU based on self.Therefore, if in the HSPA+ framework, main NodeB+ is based on this HS-DSCH data frame structure, to sending the MBMS business data packet from NodeB+, then is difficult to satisfy and eats dishes without rice or wine on the UE to merge or the requirement of soft merging.
UE is last to be eated dishes without rice or wine to merge or soft merging remains in difficulty in realization, especially relevantly how to solve the asynchronous problem that a plurality of NodeB+ send same MBMS service datas, the appearance of demanding related art scheme urgently.

Embodiment
To combine accompanying drawing that the technical scheme of the embodiment of the invention is described in further detail below.
The embodiment of the invention provides the delivery plan of MBMS business datum; In the embodiment of the invention; Require when to send the very first time of MBMS business data packet to user side according to network side by main NodeB+; The rise time indication information, and should the time indication information and the MBMS business data packet all send to from NodeB+; This time indication information is used for indication and when sends the MBMS business data packet to UE from NodeB+; , after parsing the time indication information,, when this transmitting time arrives, just the MBMS business data packet is sent from NodeB+ according to the indicated transmitting time of this time indication information.
In the embodiment of the invention, main NodeB+ is respectively based on two kinds of networking modes, and control is sent the MBMS business data packet from NodeB+.
A kind of networking mode can be referring to network structure shown in Figure 1, and wherein, main NodeB+ and between the NodeB+ directly based on the Iur interface communication, sends the concrete transmitting time of MBMS business data packet from NodeB+ through main NodeB+ control.Thereby; Down subsidiary a plurality of for a main NodeB+ from NodeB+, need each to send the situation of identical MBMS business data packet, the main NodeB+ very first time capable of using simultaneously from NodeB+; This very first time is corresponding to the RFN that sends the MBMS business data packet; Draw each from NodeB+ time corresponding indication information, then with each time indication information through and each from the Iur interface between the NodeB+, send to each accordingly from NodeB+.In this mode, though the time indication information is different, because of each time indication information corresponding to same RFN, therefore, the absolute time of each time indication information representative is basic identical.So-called basic identical, for soft merging, be meant that the deviation between the absolute time of per two time indication information representatives is no more than a TTi and a time slot sum, for the merging of eating dishes without rice or wine, then this deviation should be no more than the chip variation of requirement.
Another kind of networking mode can be referring to network architecture diagram shown in Figure 2, and wherein, main NodeB+ is based on the multicast mode; To respectively sending the MBMS business data packet from NodeB+; Correspondingly, owing to adopt multicast mode multicast time indication information, main NodeB+ only need draw a time indication information; At receiving terminal, each receives identical time indication information from NodeB+ from the IP multicast group, through after the handled, based on identical transmitting time, the MBMS business data packet is sent.Similar with first kind of mode; In this mode; So-called identical transmitting time is meant, is no more than a TTi and a chip sum from the deviation between the absolute time of NodeB+ transmission MBMS business data packet in twos, comprises being no more than the chip variation of eating dishes without rice or wine to merge requirement.
In addition, in the embodiment of the invention, in Fig. 1 or framework shown in Figure 2; Main NodeB+ control its down be example from NodeB+ transmission MBMS business datum, the concrete realization of embodiment of the invention scheme is described, wherein; If have n under the main NodeB+, remember that i is from NodeB+ from NodeB+ from NodeB+ iFrom, should be from NodeB+ iUnder P sub-district arranged, remember j from NodeB+ for from NodeB+ j, should be from NodeB+ jUnder Q sub-district arranged, i is not equal to j.In the embodiment of the invention, with from NodeB+ iIn m sub-district, and from NodeB+ jIn k sub-district for investigating the sub-district, the technical scheme that the embodiment of the invention provides is described, wherein, m=1 ..., P; K=1 ..., Q.
Referring to Fig. 7, Fig. 7 is the sending control method flow chart of MBMS business datum in the embodiment of the invention, and this flow process can may further comprise the steps:
Step 701, main NodeB+ require when to send the very first time of carrying the MBMS business data packet to UE according to the expression network side, generate expression and require when send the time indication information of said MBMS business data packet to said UE from the base station.
For the very first time of sending a MBMS business data packet; Main RNC can draw the professional merging mode of corresponding RFN:MBMS based on following message; Or the professional multiplex mode of one group of MBMS, as guaranteeing the qos requirement of speed and error rate or the like, the perhaps desired transmitting time of core net etc.Concrete calculating can be referring to related data, and the application no longer relates.The time indication information can be the sub-district of from NodeB+, sending the Frame carry the MBMS business data packet to UE, when sending this Frame, and the actual transmission CFN of this Frame.Main NodeB+ calculates each corresponding SFN in each sub-district from NodeB+ based on corresponding RFN of the very first time of calculating, and can calculate this CFN from each sub-district correspondence of NodeB+ then.Note RFN is corresponding to the clock of main RNC.
Step 702, main NodeB+ send to MBMS business data packet and time indication information from NodeB+.
Main NodeB+ utilizes main data frames to sending the MBMS business data packet from NodeB+, and in main data frames, configuration CFN.Like this, after NodeB+ receives this main data frames, parse CFN and MBMS business data packet wherein; Can know that the frame number from Frame that encapsulates this MBMS business data packet is CFN, therefore; When the CFN time corresponding arrives, should send from Frame.
So-called main data frames is meant the Frame by main NodeB+ encapsulation, and is so-called from Frame, is meant by the Frame from the NodeB+ encapsulation.
Referring to Fig. 8, Fig. 8 is the structural representation of the transmission control device of the MBMS business datum that provides of the embodiment of the invention, and this device can be arranged on the main NodeB+, comprising: information generating unit with send processing unit; Wherein,
Said information generating unit requires when to send the very first time of carrying the MBMS business data packet to UE according to the expression network side, generates expression and requires when send the time indication information of said MBMS business data packet to said UE from NodeB+;
Said transmission processing unit sends said MBMS business data packet to said dispensing device, and the said time indication information that said information generating unit is converted to is indicated to from NodeB+.
Device shown in Figure 8 belongs to main NodeB+, and respectively from can be directly based on the Iur interface communication between the NodeB+, rather than technological multicast technical communication.With the network architecture shown in Figure 1 is example, and from NodeB+, main NodeB+ is converted into RFN and is somebody's turn to do the corresponding CFN in each sub-district from NodeB+, based on main data frames this CFN is carried to each from NodeB+ to each.Get above-mentioned i=1, m=1; J=2, k=2 explains that main NodeB+ calculates the detailed way of CFN.
For the combination situation of eating dishes without rice or wine, require RFN and SFN synchronous, correspondingly, the SFN of each sub-district is synchronous.Therefore, under this situation, can directly RFN be used to calculate CFN, concrete calculating as follows:
Can directly get SFN is RFN, perhaps, gets the preset fixed value of SFN=RFN-;
Correspondingly, CFN can directly get and equal the remainder of SFN to the maximum delivery of CFN, and the span of establishing CFN is 0 to 255, then, and CFN=SFN mod 256.
For soft merging, RFN and each SFN may not be synchronous, need to consider to influence the various factors of the difference between RFN and the CFN, like the difference between the clock on each node, and the difference between the clock of each channel, or the like.The calculating of CFN is following:

For framework shown in Figure 1, main NodeB+ is with CFN 11With CFN 22Send to respectively from from NodeB+ 1With from NodeB+ 2Though CFN 11With CN 22May not be identical, but, therefore, can satisfy the synchronous requirement of soft merging owing to all being to calculate based on the deviation between each relevant each clock of RFN consideration by main NodeB+.
The calculating of above-mentioned CFN is sent out more than or equal to the frame length of a radio frames based on the Transmission Time Interval (TTI) of Frame, through the FACH channel, to sending the FACH Frame from NodeB+, and in this FACH Frame, has disposed CFN like main NodeB+.If main NodeB+ based on high-speed transmission channels such as HS-DSCH to the Frame that has been configured the time indication information from NodeB+ transmission; Then the TTI of HS-DSCH Channel Transmission is the frame length of a sub-frame usually; Usually, the frame length of subframe is M/one of the frame length of a radio frames.Get M=5, then a TTI is 2ms.Because usually CFN is that expression is a time of day with the radio frames, the frame number of corresponding Frame is then for being the situation of time of day transferring data frames with the subframe; The time indication information still can be counted the CFN from the NodeB+, just, and under this situation; The time indication information further comprises subframe frame number X, and X multiply by the subframe frame length, should be less than a radio frames frame length; Otherwise CFN adds one.Under this situation,, still can sum up as follows based on above-mentioned formula 3 and formula 4 for the calculating of CFN:
CFN=(SFN-Frameoffset+A) mod CFNmax, if τ＜38400, then, A=0; If τ＞38400, then, A=τ div 38400 chips;

Correspondingly, main NodeB+ need send to configuration CFN and X from the Frame that carries the MBMS business data packet of NodeB+.After respectively parsing CFN and X, can know the transmitting time of MBMS business data packet based on CFN and X, and carry out timing,, the Frame that carries the MBMS business data packet sent in the transmitting time of timing to CFN and X representative from NodeB+.
In addition, in the practical application, also can not adopt CFN to represent the duration that this number is corresponding, as based on the subframe frame length; The duration counting represented to CFN then correspondingly, can increase the expense of system; Therefore, preferably, can adopt CFN to represent can be based on the duration of radio frames frame length tolerance.
Referring to Fig. 9; Fig. 9 is the sending control method flow chart of the another kind of MBMS business datum that provides of the embodiment of the invention, and wherein, dominant base sends the MBMS business data packet with the multicast mode to n from the base station; N is the positive integer greater than 1, and this flow process can may further comprise the steps:
Step 901, main NodeB+ require when to send to UE very first time of MBMS business data packet according to the expression network side, generate expression require each from the base station transmitting time in appointment, send the time indication information of said MBMS business data packet to said UE.
Step 902, dominant base send said time indication information and said MBMS business data packet to each from the base station.
In the flow process shown in Figure 9, still can be each send when carrying the Frame of said MBMS business data packet the CFN of this Frame to the form of expression of time indication information to UE from NodeB+.Based on main NodeB+ with the multicast mode to send the MBMS business data packet from NodeB+; The conversion way of time indication information can have three kinds; First kind is; Eat dishes without rice or wine to merge or the constraints of the synchronous requirement of soft merging based on embodiment, this constraints is: i from NodeB+ m sub-district to the transmitting time t of UE transmission MBMS business data packet Im, with j from NodeB+ k sub-district to the transmitting time t of UE transmission MBMS business data packet JkThe absolute value of difference, need be less than or equal to a TTI and a time slot sum Δ t, convert RFN into a CFN; This same CFN is configured in the Frame that carries the MBMS business data packet,, this Frame is distributed to each from NodeB+ through IP multicast mode; Correspondingly, respectively can be based on this CFN, when the transmitting time of CFN representative arrives from NodeB+; Through from Frame, send the MBMS business data packet to UE.
Second kind is, main NodeB+ calculates one of them from NodeB+, like the CFN of i m sub-district from NodeB+ Im, with CFN ImAs the reference connection frame number of other each sub-districts, when multicast, with this CFN ImBe configured in the Frame that carries the MBMS business data packet,, this Frame be distributed to each from NodeB+, if remove individual from the NodeB+ other of i from NodeB+, based on CFN through IP multicast mode Im, send the MBMS business data packet, then can not satisfy usually and eat dishes without rice or wine to merge or the synchronous requirement of soft merging, therefore, main NodeB+ also need calculate other respectively from the corresponding CFN of NodeB+ respectively with CFN ImBetween deviation CFNoffset, and other are notified to from NodeB+ from the corresponding CFNoffset of NodeB+ with each before main NodeB+ sends this Frame; Thereby, individual for i from NodeB+, after receiving Frame, promptly can be based on the CFN that parses Im, the transmitting time of control MBMS business data packet; , individual from NodeB+, after receiving Frame, for other based on the CFN that parses like j from NodeB+ Im, and this CFNoffset from the NodeB+ correspondence that receives, can calculate this transmitting time, thereby also can control the transmission of MBMS business data packet from the actual transmission MBMS business data packet of NodeB+.If each sub-district to be sending the situation of Frame less than the sub-frame frame long hair of a radio frames frame length, in the time indication information, to remove and comprise CFN Im, also need comprise benchmark subframe frame number, this benchmark subframe frame number is i the subframe frame number X from m the sub-district of NodeB+ Im, main NodeB+ is with CFN ImAnd X ImBe configured in the main data frames of carrying the MBMS business data packet, carry to respectively from NodeB+, further, during the time indication information also comprises as the X of benchmark subframe frame number ImWith X JkBetween deviation delta X; Remove from NodeB+ iOutside other receive as after the deviation information such as each Δ X or CFNoffset from NodeB+, correspondingly calculate the actual CFN that self sends Frame.In second kind of way, actual each the self-corresponding CFN that is based on of MBMS business data packet, synchronized transmission MBMS business datum are sent in each sub-district.
The third is, main NodeB+ calculates each from the corresponding CFN of NodeB+ directly based on RFN, correspondingly, each CFN is configured in the main data frames of carrying the MBMS business data packet, and multicast is given respectively from NodeB+.After respectively receiving main data frames, resolve and draw CFN separately, based on the transmission of the corresponding MBMS business datum of this CFN control from NodeB+.In the third way, main NodeB+ calculates the CFN of each each sub-district from NodeB+ respectively, or the CFN of each sub-district and subframe frame number, and concrete calculating can be repeated no more referring to above-mentioned formula 1 to formula 5.
For the conversion of RFN to CFN, total way remains, and converts RFN into respectively belong to the sub-district from NodeB+ SFN earlier, afterwards, calculates respectively from the corresponding CFN of NodeB+ through SFN.
Corresponding to the scheme of Fig. 9 flow process, the embodiment of the invention also provides the transmission control device of another kind of MBMS business datum, and this device can be set on the main NodeB+.Referring to Figure 10, Figure 10 is the structural representation of this device.This device can comprise the multicast router through IP, and to the dispensing device transmission MBMS of n MBMS business datum business data packet, n is the positive integer greater than 1, can comprise: information generating unit and transmission processing unit; Wherein,
Said information generating unit when to the very first time of UE transmission MBMS business data packet, converts the requirement of expression network side expression into and requires each from the transmitting time of NodeB+ in appointment, sends the time indication information of said MBMS business data packet to said UE;
Said transmission processing unit sends said time indication information that said MBMS business data packet and said information generating unit draw to each from NodeB+ through the IP multicast router.
Referring to Figure 11, Figure 11 is the sending method flow chart of MBMS business datum in the embodiment of the invention, and this flow process can may further comprise the steps:
Step 1101, receive the MBMS business data packet that main NodeB+ sends, and being used to of receiving that said main NodeB+ sends indicates saidly when send the time indication information of said MBMS business data packet to UE from NodeB+ from NodeB+;
Step 1102, said from NodeB+ according to said time indication information, confirm to send the transmitting time of MBMS business data packet, when said transmitting time arrives, said MBMS business data packet is sent to said UE.
Based on scheme shown in Figure 7, and scheme shown in Figure 9, in the scheme shown in Figure 11, handle accordingly according to the time indication information that receives from NodeB+.
Referring to Figure 12, Figure 12 is the structural representation of the dispensing device of MBMS business datum in the embodiment of the invention, and this device can be arranged at respectively from NodeB+, comprising: receive processing unit, the time is confirmed unit and transmitting element, wherein,
Said reception processing unit receives the MBMS business data packet that main NodeB+ sends, and receive that main NodeB+ sends be used to indicate from NodeB+ when send the time indication information of said MBMS business data packet to UE;
The said time is confirmed the unit, according to the said time indication information that said reception processing unit draws, confirms to send the transmitting time of MBMS business data packet;
Said transmitting element when confirming that in the said time the determined transmitting time in unit arrives, sends to said UE with said MBMS business data packet.
The embodiment of the invention also provides the transmitting system of two kinds of MBMS business datums, can comprise the transmission control device of MBMS business datum shown in Figure 8 and the dispensing device of MBMS business datum shown in Figure 12 in the system; Another system can comprise the transmission control device of MBMS business datum shown in Figure 10 and the dispensing device of MBMS business datum shown in Figure 12.
Device shown in Figure 10 belongs to main NodeB+, through the IP multicast router, and respectively communicates by letter from NodeB+.With the network architecture shown in Figure 2 is example, and earlier the main NodeB+ of explanation is based on constraints, converts RFN into the situation of a CFN, promptly above-mentioned first kind of way.
In the realization of first kind of way; Utilize RFN to calculate the concrete realization of CFN for the combination situation of eating dishes without rice or wine; Can during directly based on the Iur interface communication,, repeat no more referring to above-mentioned main NodeB+ and between NodeB+ to how calculating the associated description of CFN under this combination situation of eating dishes without rice or wine.In the present embodiment, calculate after the CFN, main NodeB+ brings each from NodeB+ through carrying the Frame of MBMS business data packet with this CFN.
In the realization of first kind of way, for soft combination situation, because also asynchronous between RFN and each SFN; Therefore; If main NodeB+ calculates each from NodeB+ CFN separately directly based on RFN, and then each CFN may not be identical; Main NodeB+ is also just based on the multicast mode, to respectively sending CFN and different from NodeB+.Therefore, based on taking all factors into consideration of soft merging and multicast mode, can be by main NodeB+; Based on the constraints of soft merging, calculate one as far as each from NodeB+, the CFN of appropriate; So-called suitable being meant; Based on this CFN, the time deviation between per two transmitting times of sending the same MBMS service data bag from NodeB+ all can not surpass Δ t.
For ease of calculating the CFN that respectively all is suitable for from NodeB+, preferably, optional one the 1st from NodeB+ 1In the 1st sub-district be reference cell, correspondingly,, calculate the CFN of this sub-district based on constraints 11Afterwards, can be with CFN 11As each from NodeB+ the CFN that can use jointly Ref, with this CFN 11Multicast is given respectively from NodeB+.CFN 11Calculating specific as follows:
In the embodiment of the invention, calculate CFN 11Key be that main NodeB+ is to the configuration of each channel clock, to select suitable Frameoffset and τ, analyze as follows:
For CFN 11Calculating, still calculate based on formula 1 to formula 4, integrating representation is:
CFN＝(SFN-Frameoffset+A)mod?256。
Based on constraints, calculate CFN 11Can be regarded as,, be about to each CFN and adjust to a suitable relatively value the adjustment of each CFN.From the calculation expression of CFN, the factor that influences CFN can simply be interpreted as three, and promptly SFN, Frameoffset also can comprise τ.Adjust that each SFN normally is difficult to accomplish because, the calculating of SFN usually with the clock of main NodeB+, from the clock of NodeB+, from the sub-district clock of NodeB+; Time deviation between each clock is relevant, if will adjust SFN, then actual is the clock that will adjust the whole network; Difficulty is bigger, in the embodiment of the invention, can adjust the clock of each channel through main NodeB+; Promptly adjust Frameoffset and τ, adjust each CFN, be about to each CFN and adjust to a common CFN 11On.Correspondingly, the constraints of relevant Δ t develops into the constraints to Frameoffset and τ, and it is following that the embodiment of the invention provides this constraints:
Framoffset 11-Frameoffset 22=SFN 11Mod 256-SFN 22Mod 256; Formula 6
Main NodeB+ selectes Framoffset according to formula 6 11, calculate CFN again 11If consider the influence of τ, then the embodiment of the invention provides corresponding constraints and is:
Framoffset 11-Frameoffset 22+τ 11div?38400-τ 22div?38400
=SFN 11Mod 256-SFN 22Mod 256; Formula 7
Main NodeB+ selectes Framoffset according to formula 7 1, τ 1, calculate CFN again 11
The CFN that main NodeB+ calculates 11Can be used as can be by from NodeB+ 1With from NodeB+ 2The common CFN that uses is multicast to from NodeB+ 1With from NodeB+ 2
For there being more a plurality of situation in the networking from NodeB+; Correspondingly; Main NodeB+ takes all factors into consideration Frameoffset and each τ that respectively goes up each sub-district from NodeB+, selects suitable Framoffset1 and τ, can be by the CFN that respectively uses jointly from NodeB+ to calculate.
Above-mentioned main NodeB+ issues respectively the situation of the CFN that can use jointly from NodeB+ with the multicast mode, be applicable to usually like the above-mentioned combination situation of eating dishes without rice or wine, also applicable to TTI greater than the situation of the frame length of a radio frames as carrying out transfer of data based on the FACH channel.
For the realization of second kind of way, as before mention, during soft merging; For situation based on multicasting technology multicast time indication information, above-mentioned except that adopting, be respectively to calculate outside the scheme of a CFN that can use jointly by main NodeB+ from NodeB+; Also can adopt, be reference cell by main NodeB+ with certain sub-district, calculates the CFN from the NodeB+ correspondence of this reference cell; With this CFN as other respectively from the reference connection frame number of the CFN of NodeB+, remember that this reference connection frame number is CFN Ref, with this CFN RefThrough carrying the Frame of MBMS business data packet, multicast is given respectively from NodeB+, and main NodeB+ will be respectively from CFN and this CFN of NodeB+ RefBetween difference CFN Offset, be transferred to corresponding respectively from NodeB+ through physical channel.
Below with from NodeB+ 1In sub-district 1 be reference cell, divide two kinds of situation to explain that main NodeB+ calculates CFN RefAnd CFN OffsetWay.
Way one:
TTI is more than or equal to the frame length of a radio frames.According to formula 1 to 4, can calculate from NodeB+ 1The corresponding CFN in sub-district 1 11The embodiment of the invention provides from NodeB+ 22The CFN of sub-district 2 22With CFN 11Between CFN OffsetAlgorithmic formula 8:
CFNoffset? 22＝Framoffset 11-Frameoffset 22+τ 11div?38400-τ 22div?38400。Formula 8
Correspondingly, receive CFN from NodeB+ for the 2nd 11And should be from the corresponding CFNoffset of NodeB+ 22After, the transmitting time of determining the MBMS business data packet is corresponding to CFN 22With CFNoffset 22Sum is carried out timing, when this transmitting time arrives, with the MBMS business data packet through sending from Frame.
Way two:
TTI is less than the frame length of a radio frames, and getting the subframe frame length like TTI is 2ms, correspondingly, and CFN 11As CFN Ref, from NodeB+ 1In the subframe frame number X of the 1st sub-district 11Be benchmark subframe frame number, CFN Ref' and X RefCFN RefCan be referring to above-mentioned correlation formula, X RefCalculating can be referring to above-mentioned formula 5.
From NodeB+ 2The X of middle sub-district 2 22With X RefBetween the following formula 9 of algorithmic formula of deviation:
ΔX＝[((T cell11+RFN_BFN 1_chipoff)-(T cell21+RFN_BFN 2_chipoff))/7680]；
Formula 9
7680 obtain divided by the multiple 5 of radio frames frame length to the subframe frame length by 38400.
In the formula 9, the implication of " [] " is, result of calculation is rounded, and promptly gets the nearest integer greater than this value.In addition, in the formula 9, T Cell11, T Cell22, RFN_BFN 1_ chipoff, RFN_BFN 2_ chipoff maybe be for negative.
Through the Δ X that formula 9 is calculated, CFN RefWith X RefBeing configured in the main data frames multicast gives respectively from NodeB+.
Correspondingly, from NodeB+ 1Parse CFN RefWith X RefAfter, can directly confirm the transmitting time of MBMS business data packet, when this transmitting time arrives, with carrying sending of MBMS business data packet from Frame.From NodeB+ 2Parse CFN RefWith X Ref, and, calculate corresponding C FN based on the Δ X that receives 22With X 22, algorithm is following:
Calculate X Ref-Δ X;
If (X Ref-Δ X)＜0, CFN then 22=CFN Ref-1, and X 22=5+ (X Ref-Δ X)
If (X Ref-Δ X)＞5, CFN then 22=CFN Ref+ 1, and X 22=(X Ref-Δ X) mod 5.
Thereby also can be based on the CFN that calculates from NodeB+2 22And X 22, when the transmitting time of correspondence arrives, with the MBMS business data packet through sending from Frame.
Above-mentioned way two is applicable to the situation of Frame based on the HS-DSCH Channel Transmission.
