Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
In the TD-SCDMA system, as shown in Figure 1, in the UTRAN of Releas7 (R7), RNC is according to the main loaded service kind in each sub-district, and the sub-district of its control is divided into MBMS sub-district and common sub-district.The MBMS sub-district is main with the MBMS business, and the MBMS business has taken a large amount of time slot and the code channel resources in this sub-district, and RNC also allows in this sub-district, to use resource bearing general servicies such as a spot of time slot and/or code channel simultaneously; Common sub-district is main with non-MBMS business, and general service has taken a large amount of time slot and the code channel resources in this sub-district, and it is professional that RNC also allows in this sub-district, to use resource bearing MBMS such as a spot of time slot and/or code channel simultaneously.So-called MBMS sub-district and common sub-district only are that RNC defines according to the main loaded service type in each sub-district; Along with change of time; These sub-district institute loaded service possibly change, and mainly carry the professional sub-district of MBMS owing to the professional minimizing of MBMS is changed to non-MBMS business such as main voice-bearer, and the MBMS business also can mainly be carried in common sub-district; In a word, MBMS sub-district and common sub-district can transform each other.
The MBMS sub-district can adopt different frequencies to cover same physical region with common sub-district, that is to say, the UE in certain place possibly covered by the sub-district of a plurality of covering same area, and different frequencies is adopted in these different sub-districts.
RNC allows each sub-district, comprises MBMS sub-district and common sub-district, all resident UE.That is to say that UE can comprise MBMS business or general service according to its business of carrying out, both can reside in the MBMS sub-district and also can reside in the common sub-district.
In this embodiment, introduction be double-receiver single transmit machine UE, hereinafter to be referred as double-receiver R7UE; UTRAN is the network of R7, allows double-receiver R7UE to insert simultaneously with two receivers and carries out different service.
A double-receiver R7UE resides in the sub-district, and this double-receiver R7UE can carry out the Signalling exchange of up-downgoing with UTRAN, is accomplished to UE authentication and registration of core net etc. in this sub-district; Another receiver of this double-receiver R7UE can receive downstream signal in another sub-district simultaneously; Carrying out only is descending business; Professional like MBMS, this double-receiver R7UE can not send upward signal to Node B in this sub-district, can not carry out Signalling exchange in this sub-district and UTRAN.
Among Fig. 1,2 same cell covered of alien frequencies are arranged on the place of double-receiver R7UE, a frequency is the MBMS sub-district, and another frequency is common sub-district.Double-receiver R7UE resides in common sub-district, and another receiver of double-receiver R7UE can receive the MBMS business of the MBMS sub-district of another frequency simultaneously.
In the TD-SCDMA system, a double-receiver R7UE resides in the sub-district (i.e. first sub-district), and Fig. 2 has described double-receiver R7UE and received the professional idiographic flow of MBMS, may further comprise the steps:
Said MBMS business comprises multicast service and broadcasting service.
Double-receiver R7UE can pass through multiple modes such as SMS, website, FTP, obtains said professional statement.
Professional application comprises the request of permission double-receiver R7UE and the scope of said MBMS business, and professional statement was used for to the ip multicast address of certain MBMS business of double-receiver R7UE issue and professional time started etc.
Through adding said multicast service, double-receiver R7UE obtains the authentication verification of this multicast service, and the IP that sets up relevant multicast service then carries.
At this moment; Said MBMS business is a broadcasting service; Double-receiver R7UE is carrying professional this broadcasting service of location activation of said MBMS; That is: double-receiver R7UE discord UTRAN carries out Signalling exchange, and the IP that double-receiver R7UE sets up this broadcasting service in the location of having carried said MBMS business carries.
The wherein said professional location of said MBMS of having carried comprises first sub-district and the neighbor cell that has carried said MBMS business.
MBMS professional control messages (the MBMS Modified services Information of double-receiver R7UE through carrying on the MCCH channel that reads first sub-district; " MBMS revises business information " message), confirm that said MBMS business is issued in first sub-district or carrying the professional neighbor cell issue of said MBMS.
Wherein the MCCH channel is the professional control channel of MBMS.
At this moment, said MBMS business is issued in first sub-district, is the frequency of first sub-district for the frequency of this MBMS business configuration on the MCCH channel of first sub-district then.
Wherein the MICH channel is the professional indicating channel of MBMS.
In the system broadcast message piece 5 (System Information Block type 5 and5bis) of first sub-district, disposed the information of the physical channel (S-CCPCH) and the transmission channel (FACH) of MCCH channel; In " MBMS general information " (MBMS GeneralInformation) of the MCCH of first sub-district channel, disposed the physical layer information such as time slot, code channel, repetition period of MICH channel; MICH channel and the configuration information of MCCH channel of double-receiver R7UE through reading first sub-district can know (which time slot, which code channel etc.) read MICH channel and MCCH channel on which position.
At this moment; Said MBMS business is being carried the professional neighbor cell issue of said MBMS; Be the frequency that has carried the professional neighbor cell of said MBMS for the frequency of this MBMS business configuration on the MCCH channel of first sub-district then; Double-receiver R7UE having carried the professional neighbor cell of said MBMS (these have carried the professional neighbor cell of said MBMS is identical frequency), reads MCCH channel and MICH channel with its another receiver.
Because this MBMS business possibly issued a plurality of the carrying in the professional neighbor cell of said MBMS simultaneously; So double-receiver R7UE is according to neighbor cell list; And the carrying of further measuring according to double-receiver R7UE the signal quality of the professional neighbor cell of said MBMS, select the good sub-district of one of them signal quality (i.e. second sub-district) to receive this MBMS business.
In the system broadcast message piece 5 (System Information Block type 5 and5bis) of second sub-district, disposed the information of physical channel (S-CCPCH) and the transmission channel (FACH) of MCCH; In " MBMS general information " (MBMS GeneralInformation) of the MCCH of second sub-district channel, disposed the physical layer information such as time slot, code channel, repetition period of MICH channel; MICH channel and the configuration information of MCCH channel of double-receiver R7 double-receiver R7UE through reading second sub-district, double-receiver R7 double-receiver R7UE can know (which time slot, which code channel etc.) read MICH channel and MCCH channel on which position.
When double-receiver R7UE resides in first sub-district; And when reading professional MCCH channel of said MBMS and MICH channel in first sub-district; No matter this MBMS business is multicast or broadcasting service, no matter also be that PTM carries or PTP carries (if multicast service), the Traffic Channel MTCH channel configuration of this MBMS is in first sub-district; Certainly, MICH channel, MCCH channel also are configured in first sub-district.In a word, double-receiver R7UE resides in first sub-district, and at the first sub-district receiving control message, Indication message and MBMS professional (this moment, the MBMS service bearer was on the MTCH channel).
If said MBMS business is a broadcasting service, this broadcasting service adopts PTM to carry.
When said MBMS business is multicast service; Then the RNC statistics needs the number (sub-district of the control messages of the said double-receiver R7UE receiving multimedia broadcast multicast service of RNC statistics issue of the sub-district that said double-receiver R7UE is resident needs the double-receiver R7UE number of receiving multicast business) of the double-receiver R7UE of receiving multicast business; RNC sends the counting request message on the MCCH channel have counting process, needs a part of double-receiver R7UE of receiving multicast business to send counting response message to RNC; RNC is according to the double-receiver R7UE number of response count; Just can count the number that needs the double-receiver of receiving multicast business R7UE; Thereby the bearing mode of confirming this multicast service is (if double-receiver R7UE number is few; Then RNC can set up the PTP carrying for this multicast service, if double-receiver R7UE number is many, then RNC can set up the PTM carrying for this multicast service).
For multicast service, when adopting PTP to carry owing to UE quantity smaller or equal to threshold value G (threshold value G is the positive integer smaller or equal to 15), RNC sets up PTP to each UE and carries; Because UE quantity is few, the shared Radio Resource of these UE is very not many, and the power that Node B sends is less; Do not need the professional UE of this MBMS for other like this; The interference that causes is less, and when PTP carried, it is relatively good that UE receives the professional signal quality of this MBMS; When UE quantity greater than threshold value G, when adopting PTM to carry, RNC is traffic assignments one cover Radio Resource for this reason, all need the professional UE of this MBMS all to use this Radio Resource, have saved resource.
Double-receiver R7UE is still residing in first sub-district, adopts PTP to carry in first sub-district and receives the MBMS business, uses its another receiver at second sub-district receiving control message and the Indication message simultaneously.
When adopting PTP to carry, R7UE has only a transmitter, and it is professional that UE can only receive this MBMS that PTP carries in first sub-district, because PTP is when carrying, UE and RNC must carry out the information interaction of up-downgoing.
At this moment, the professional Traffic Channel MTCH of MBMS is configured in second sub-district, and certainly, MICH channel, MCCH channel also are configured in second sub-district.In a word, double-receiver R7UE resides in first sub-district, and with another receiver at the second sub-district receiving control message, Indication message and MBMS professional (this moment, the MBMS service bearer was on the MTCH channel).
When adopting PTM to carry, this MBMS business has only downlink data, so can be professional at the second sub-district receiving control message, Indication message and MBMS.
It is professional that step 270, double-receiver R7UE finish receiving said MBMS, carries out professional (Leaving) process of leaving of said MBMS.
In the reality, RNC need add up needs the double-receiver of receiving multicast business R7UE number.The MBMS sub-district is called for short in the main professional sub-district of MBMS of carrying, its main bearing multimedia broadcast multicast service and a small amount of speech business; Common sub-district is called for short in the main professional sub-district of non-MBMS of carrying, its main carry voice traffic and a small amount of multimedia broadcast-multicast service.Fig. 3 is the sketch map of certain multicast service count results of RNC statistics in the specific embodiment of the invention, is divided into dual mode, and is specific as follows:
First kind of mode: common sub-district and MBMS sub-district are all in a RNC, like the RNC1 of Fig. 3.
Be provided with a RNC control down, a MBMS sub-district arranged, a plurality of common sub-districts.
When the RNC under the MBMS sub-district on the MCCH channel to the professional counting process of initiating of certain MBMS, then:
Reside in the double-receiver R7UE of said MBMS sub-district; Just accomplish the counting response process in this MBMS sub-district; And the double-receiver R7UE that resides in other common sub-district accomplishes the counting response process in resident separately sub-district, because these sub-districts are all at a RNC, so RNC can obtain the professional count results of this MBMS of double-receiver R7UE response of all sub-districts; RNC judges that according to the result of the professional counting response of this MBMS this MBMS business is to adopt PTP to carry or the PTM carrying.
The second way: common sub-district and MBMS sub-district are RNC1 and RNC2 among Fig. 3 between a plurality of RNC, are not limited to 2 in the reality certainly, and a plurality of RNC can be arranged.
Be provided with a RNC control down, a MBMS sub-district is arranged, a plurality of common sub-districts are arranged.Simultaneously, also have many common sub-districts under other RNC control, and Iur interface (two RNC between interface) is arranged between the RNC.As shown in Figure 4, when the RNC under the MBMS sub-district (RNC1 of Fig. 3) on the MCCH channel to the professional counting process of initiating of certain MBMS, then:
The double-receiver R7UE of step 320, common sub-district is with the counting response result of feedback; Be reported to the affiliated RNC of these common sub-districts; If these RNC (RNC2 of Fig. 3) are not the RNC under the MBMS sub-district; Then through the Iur interface, the count results of these common sub-districts is forwarded to the RNC (RNC1 of Fig. 3) under the MBMS sub-district;
RNC (RNC1 of Fig. 3) under step 330, the MBMS sub-district can obtain in all sub-districts the professional count results of this MBMS.
The above is merely signal execution mode of the present invention; Should know that this can have many modification; This modification is not considered to break away from the spirit and the scope of signal execution mode of the present invention, and the conspicuous modification of all such those of ordinary skills is comprised within the scope of accompanying claims.
