Description

The transmission of MBMS control information, acquisition methods and device
Technical field
The present invention relates to wireless communication technology, relate to transmission, acquisition methods and the transmission control unit of user terminal, MBMS control information particularly.
Background technology
(Multimedia Broadcast/Multicast Service MBMS) is one of the important content of third generation partner program (3rd Generation Partnership Project, i.e. 3GPP) business development to multicast service.MBMS refers to that mainly network side simultaneously sends to a plurality of recipients in the network to identical multi-medium data.3GPP uses the folding of eating dishes without rice or wine to strengthen the MBMS signal strength signal intensity, improves laser propagation effect.The employing folding of eating dishes without rice or wine can effectively be utilized the signal of adjacent sub-district, reaches the purpose of improving laser propagation effect.
For the scope of eating dishes without rice or wine to merge, 3GPP defined maximum MBMS assembly section, many sub-districts (Multi-cellMBMS Synchronization Area, MMSA) and single frequency network area (Single Frequency NetworkArea, SFA) two notions.MMSA comprises one group of sub-district that coverage is continuous, and there is identical band resource these sub-districts.After configuration, Single Frequency Network can be used in the sub-district in the MMSA, and ((UserEquipment UE) can eat dishes without rice or wine to merge thereby make user terminal for SingleFrequency Network, SFN) mode synchronized transmission MBMS business.SFA comprises one group of sub-district that coverage is continuous, and identical Radio Resource in the identical frequency band, the some MBMS business of synchronized transmission are used in these sub-districts.MMSA represents maximum possible SFA set, and SFA can enlarge in MMSA or dwindle, but can not exceed MMSA.
The 3GPP regulation, the object of eating dishes without rice or wine to merge not only comprises the MBMS business datum, also comprises the MBMS control information.According to the difference of the professional send mode of MBMS, also there is different send modes in the MBMS control information.The MBMS business has three kinds of send modes:
1, Dan Qu (Single Cell) pattern: MBMS is professional only sends in this sub-district, does not need to eat dishes without rice or wine to merge with adjacent cell signal.
The non-Single Frequency Network in sub-district more than 2 (SFN) send mode: the MBMS business sends in a plurality of sub-districts, but the signal of each sub-district does not require strict synchronism, and UE can't do the MBMS service signal of a plurality of sub-districts of receiving and eat dishes without rice or wine to merge.
3, Single Frequency Network (SFN) pattern: in SFA, use identical time-frequency domain resources to send identical MBMS business, when receiving this business from sending this professional sub-district, can this professional signal in these different districts be merged by the folding of eating dishes without rice or wine, be considered as a signal.Under this send mode, the MBMS business sends in the SFA scope, and the sub-district in the SFA scope needs the synchronized transmission should business, UE can be done this MBMS business eat dishes without rice or wine to merge.
If the MBMS business sends in the non-Single Frequency Network mode of Single cell pattern or many sub-districts in certain sub-district, this business control information corresponding only needs to transmit in this cell range; If the MBMS business transmits with the SFN pattern in SFA, this business control information corresponding is divided into two parts: the MBMS control information that need eat dishes without rice or wine to merge and need not the MBMS control information of eating dishes without rice or wine to merge.Therefore the range of transmission difference of these two kinds of MBMS control informations need be two kinds of different transmission methods of MBMS control information planning.
At present, industry proposes to address the above problem with following technical proposal:
(MBMS Control Channel is MCCH) with a plurality of annexable MBMS control channels for the MBMS control channel of two cell-specific of each little block reservation.The MCCH of one of them cell-specific is used to transmit all MBMS service lists and send modes thereof in the basic control information, sub-district of sub-district, and the index information of these professional corresponding MCCH; UE can find other MCCH of this sub-district according to index information.The MCCH of another cell-specific is used to transmit in this sub-district the control information of all MBMS business that send with single cell pattern, this MCCH can comprise the control information of a plurality of MBMS business, and these MBMS business must adopt non-SFN mode to send in this sub-district.The all corresponding MBMS business that sends in the SFN mode of each annexable MCCH is used to transmit the control information of this MBMS business, and can merges with other sub-district corresponding M CCH in the SFA of correspondence scope.There are several MBMS business that can merge a sub-district, just corresponding several MCCH that can merge.
When UE receives MBMS information in the sub-district, read the MCCH of cell-specific earlier, all MBMS service lists and send modes thereof of providing in the sub-district are provided.If UE finds the business of oneself wanting to receive and sends with single cell pattern in this sub-district, then UE reads this business control information corresponding from the MCCH of another cell-specific, thereby get access to MBMS Traffic Channel (the MBMS TrafficChannel of this business correspondence, MTCH) information receives the MBMS business by MTCH then; If UE finds the business of oneself wanting to receive and sends in the SFN mode in this sub-district, then UE reads the MCCH index information among the cell-specific MCCH, information finds the annexable MCCH corresponding with this business in view of the above, and then read this annexable MCCH, obtain this professional control information, get access to corresponding MTCH information, receive the MBMS business by corresponding MTCH at last.
By technique scheme, the control information of the business that sends by different way is able to correctly, reasonably transmits, but also there is following deficiency in technique scheme:
If a sub-district sends a plurality of MBMS business with the SFN pattern simultaneously, just need many of the foundation correspondence can merge MCCH, the merging zone that these MCCH are corresponding different.When the new professional beginning of MBMS that sends in the SFN mode, need for it newly-built one can merge MCCH to transmit its control information; And need be in the SFA of this new business correspondence, this control information of synchronous transmission on the merged MCCH corresponding with other sub-district; After a MBMS service ending that sends in the SFN mode, also need to delete corresponding with it merged MCCH.Set up continually, delete and to merge MCCH and not only bring extra work burden, and behind each newly-built MCCH, need through corresponding merged MCCH synchronized transmission control information in other sub-district in accurate synchronizing process ability and the SFA, very high to the requirement of user's face.
On the other hand, when UE switches, need read the MCCH of cell-specific again between different MBMS business, obtain the MCCH index information, find target MCCH according to index again, read the control information of target service, just can find target MTCH channel then, begin to receive the MBMS business.Handoff procedure need read 3 logic MBMS control channels successively, causes switching time longer, and user satisfaction is low.
In addition, the folding of eating dishes without rice or wine especially has superiority for big data on flows, and each annexable MCCH only is used to transmit a part of control information of a MBMS business in this scheme, and data volume is very little, fails to make full use of the superiority of folding of eating dishes without rice or wine.

Embodiment
Below in conjunction with accompanying drawing the present invention is done further in detail clearly explanation.
Fig. 1 shows the schematic flow sheet of an embodiment of the transmission method of MBMS control information among the present invention.Its concrete steps are as follows:
Step S1001, transmission comprises the information of the send mode of the tabulation of all available multicast/multicast services of this sub-district and each described multicast/multicast service on the MBMS control channel of each sub-district in maximum MBMS assembly section, many sub-districts.
That is transport service concordance list (corresponding send mode) on a MBMS control channel.In addition, the content of this MBMS control channel transmission also comprises the basic MBMS control information that this sub-district is general, indicates as MCCH etc.The one MBMS control channel and concrete MBMS independent of service, MBMS is professional to be sent as long as this sub-district has, no matter business in which kind of mode sends, this channel just must exist; If this sub-district does not have the professional transmission of MBMS, this channel also can exist.As another kind of execution mode, the content of on a MBMS control channel, transmitting, comprise basic MBMS control information that professional concordance list, this sub-district are general etc., also can be at Broadcast Control Channel (the Broadcast Control Channel of this sub-district, BCCH) or the MBMS scheduling channel (MBMS point-to-multiple point Scheduling Channel MSCH) goes up transmission.
Step S1002, when the multicast/multicast service in the maximum MBMS assembly section, described many sub-districts sends in the Single Frequency Network mode, the pairing control information of this multicast/multicast service of synchronous transmission on the 3rd MBMS control channel of each sub-district in maximum MBMS assembly section, described many sub-districts.
For the sub-district in the MMSA, as long as there is the MBMS business that sends in the SFN mode in this MMSA, no matter whether this MBMS business sends in this sub-district, this sub-district all must have described the 3rd MBMS control channel to transmit the control information of this MBMS business.That is, for each sub-district, the MBMS business that this MCCH goes up transmission is not all effective in this sub-district.
Certainly, if this multicast/multicast service sends in the non-Single Frequency Network mode of single district mode or many sub-districts, also there is step S1003:
Step S1003, when the multicast/multicast service in the maximum MBMS assembly section, described many sub-districts sends in the non-Single Frequency Network mode of single district mode or many sub-districts, the control information of this multicast/multicast service of transmission on the 2nd MBMS control channel of the sub-district that sends this multicast/multicast service.
The necessary and sufficient condition that the 2nd MBMS control channel of described sub-district exists is that this sub-district exists the MBMS business that sends in the non-SFN mode of single district mode or many sub-districts.When described MBMS business sends in a sub-district in single district mode, its control information is transmitted on the 2nd MBMS control channel of described sub-district; When described MBMS business sends in a plurality of sub-districts in the non-SFN mode in many sub-districts, its control information is transmitted on the 2nd MBMS control channel of each sub-district of described a plurality of sub-districts.
Need to prove not have strict time order and function order between above-mentioned three steps.
Transmission method by above-mentioned MBMS control information, make in the MMSA of place, sub-district all synchronous transmission on the 3rd MBMS control channel of each sub-district in this MMSA of all professional pairing control informations of MBMS that send in the SFN mode, thereby make when the MBMS business that sends in the SFN mode has to increase/when subtracting, only need be in the professional concordance list in the MBMS control channel this professional index entry of increase/deletion, and in MMSA on the 3rd MBMS control channel of each sub-district this professional control information of adding/deletion get final product, need not newly-built/deletion MBMS control channel, alleviated work load, and saved synchronizing step, reduced requirement to user's face.
The one MBMS control channel is the MCCH of this cell-specific, and control information is transmitted in single district mode thereon.Equally, the 2nd MBMS control channel also is the MCCH of this cell-specific, and control information is also transmitted in single district mode thereon.The 3rd MBMS control channel is the MCCH that share each sub-district in the MMSA, and control information is thereon with SFN mode synchronous transmission, and the 3rd MBMS control channel of each sub-district can utilize the folding of eating dishes without rice or wine to combine in the MMSA.Each transmits on the 3rd MBMS control channel in the mode of time-division with the professional pairing control information of MBMS that the SFN mode sends, also can be multiplexed into the professional pairing control information of all MBMS that send in the SFN mode in the transmission block of the 3rd MBMS control channel and transmit, perhaps, two or more multicasts that send in the Single Frequency Network mode/multicast service control information corresponding is multiplexed into a transmission block, and each transmission block transmits on described the 3rd MBMS control channel with time-division or frequency division mode.Certainly, above-mentioned transmission means is an employed mode in the present embodiment, and in fact, described first, second, third MBMS control channel also can transmit described control information in other mode; As a kind of execution mode, described the 3rd MBMS control channel also can merge.
Certainly, we can also transmit transmitting block index information on a MBMS control channel of sub-district, described transmitting block index information is all business that send in the Single Frequency Network mode and the index information of the pairing described transmission block of its control information in the maximum MBMS assembly section, many sub-districts under the sub-district, promptly, two of concordance list, X and Y concern one to one, here, X refers to the business that sends in the Single Frequency Network mode, and Y refers to the transmission block at its control information place.By this transmitting block index information, can make user terminal find the transmission block at the control information place of target service more easily.For example, if target service is A, it sends in the Single Frequency Network mode, by searching transmitting block index information, discovery is transmission block B with the pairing list item of professional A, the control information that then can learn professional A is transmitted in transmission block B, just can arrive the control information of obtaining professional A among the transmission block B of the 3rd MBMS control channel then.
All have effectively utilized the superiority of the folding of eating dishes without rice or wine with the professional pairing control information of MBMS that the SFN mode sends in the transmission MMSA on annexable the 3rd MBMS control channel.
Need to prove that a described MBMS control channel and the 2nd MBMS control channel can unite two into one, and also can separate.Can be with them separately or unite two into one according to the situation of each sub-district and needs.
Corresponding to the transmission method of above-mentioned MBMS control information, the embodiment of the invention also provides a kind of acquisition methods of MBMS control information, and Fig. 2 shows the schematic flow sheet of this method one embodiment, may further comprise the steps:
Step S2001 obtains the tabulation of these all available multicast/multicast services of sub-district and the send mode of each described multicast/multicast service from a MBMS control channel of user terminal institute persistent district;
Step S2002 when the send mode that draws target multicast/multicast service according to described service lists and described send mode is the Single Frequency Network mode, obtains the control information of described target multicast/multicast service from the 3rd MBMS control channel of described sub-district.
Certainly, if target service sends in the non-Single Frequency Network mode of single district mode or many sub-districts, also comprise step S2003:
Step S2003 when the send mode that draws target multicast/multicast service according to described service lists and described send mode is the non-Single Frequency Network mode in single district mode or many sub-districts, obtains its control information from the 2nd MBMS control channel of described sub-district.
Here, when a MBMS control channel of described sub-district and the 2nd MBMS control channel unite two into one, promptly a MBMS control channel and the 2nd MBMS control channel are combined into a MCCH, when being referred to as a MBMS control channel, be to obtain described control information in this step from a MBMS control channel.Perhaps, when described service lists and described send mode transmit, need obtain described service lists and described send mode on the BCCH of described sub-district or MSCH from described BCCH or MSCH.
Fig. 3 shows the specific embodiment schematic flow sheet of step S2003, comprising:
Step S3001 obtains all pairing control informations of multicast/multicast service that send in the Single Frequency Network mode in the maximum MBMS assembly section, many sub-districts, place, described sub-district from the 3rd MBMS control channel of described sub-district;
Here, the embodiment that obtains described control information can be the transmission block that obtains to comprise described control information from the 3rd MBMS control channel of described sub-district.
Step S3002 searches and obtains the pairing control information of target multicast/multicast service the pairing control information of multicast/multicast service that all in maximum MBMS assembly section, many sub-districts, place, described sub-district send in the Single Frequency Network mode.
When also transmission had transmitting block index information on the MBMS control channel, the concrete implementing procedure of another of described step S2003 may further comprise the steps:
Step S4001, query transmission piece index information from the described MBMS control channel, determine the pairing transmission block of control information of described target multicast/multicast service, described transmitting block index information is the business that sends in the Single Frequency Network mode and the index information of its control information place transmission block;
Step S4002 obtains the content of described transmission block from the 3rd MBMS control channel of described sub-district;
Step S4003 searches and obtains the pairing control information of target multicast/multicast service in described transmission block content.
Acquisition methods by above-mentioned MBMS control information, when user terminal switches between different MBMS business, only need read a MBMS control channel again, send mode according to target service gets final product from the 2nd MBMS control channel of correspondence or the control messages of the 3rd MBMS control channel acquisition correspondence, simplified switching flow, improve switch speed, improved user satisfaction.And, by this method, increase when the MBMS business that sends in the SFN mode has/when subtracting, only need be in the professional concordance list in the MBMS control channel this professional index entry of increase/deletion, and in MMSA on the 3rd MBMS control channel of each sub-district this professional control information of adding/deletion get final product, need not newly-built/deletion MBMS control channel; When certain professional pairing SFA of MBMS that sends in the SFN mode changes (SFA enlarges or dwindles), only need newly add/leaving this professional index entry of increases/deletion in the professional concordance list in the MBMS control channel of sub-district of SFA, need not newly to add/leaving newly-built in the sub-district of SFA/delete MCCH; Thereby alleviated work load, and saved synchronizing step, reduced requirement user's face.
Provide transmission and acquisition methods that concrete Application Example illustrates above-mentioned MBMS control information below.
Fig. 4 should have A, B, C, D, five sub-districts of E with the configuring condition schematic diagram of a MMSA among the embodiment in this MMSA, have 4 MBMS business and send, and the transmission situation is as follows:
-professional 1 uses the SFN mode to send in the SFA1 scope, and SFA1 comprises two sub-districts of A, B.
-professional 1 uses single cell mode to send in the D of sub-district.
-professional 2 use the SFN mode to send in the SFA2 scope, and SFA2 comprises B, C, three sub-districts of D.
-professional 3 use the SFN mode to send in the SFA3 scope, and SFA3 comprises two sub-districts of C, D.
-professional 4 use single cell mode to send in the E of sub-district.
Corresponding diagram 4, the index that a MBMS control channel of each sub-district is transmitted is as follows:
-A: professional 1 SFN mode
-B: professional 1 SFN mode
Professional 2 SFN modes
-C: professional 2 SFN modes
Professional 3 SFN modes
-D: professional 1 single cell mode
Professional 2 SFN modes
Professional 3 SFN modes
-E: professional 4 single cell modes
The control information correspondence that the 2nd MBMS control channel of each sub-district is transmitted is as follows:
-A: no content
-B: no content
-C: no content
-D: professional 1 control information
-E: professional 4 control information
The 3rd MBMS control channel of each sub-district is for can merge MCCH, and the control information that it transmits the MBMS business that all use SFN modes send in this MMSA scope comprises professional 1,2,3.
When UE receives certain MBMS business in the sub-district, read a MBMS control channel of sub-district earlier, obtain the MBMS basic configuration information of sub-district, and the professional concordance list of the MBMS in this sub-district, the send mode of this MBMS business obtained in this sub-district.If the business that UE prepares to receive sends in the singlecell mode in the sub-district, then read professional concrete control information from the 2nd MBMS control channel, comprise the configuration of corresponding service channel MTCH etc., obtain business datum by MTCH at last.If the business that UE prepare to receive sends in the SFN mode in the sub-district, then read this professional control information from the 3rd MBMS control channel, again according to control information, the MTCH by correspondence reads business datum.
As shown in Figure 4, if UE resides among the D of sub-district, want to receive professional 1.Then, UE reads the service lists transmitted on the MBMS control channel of sub-district D earlier, knows that professional 1 sends in the singlecell mode in the D of sub-district.UE continues to read the 2nd MBMS control channel of sub-district D, knows professional 1 traffic channel configuration information in the D of sub-district, according to configuration information read professional 1 in the D of sub-district corresponding MTCH, obtain business datum.
If UE resides among the D of sub-district, want to receive professional 3.Then, UE reads the service lists that transmits on the MBMS control channel of sub-district D earlier, know that professional 3 send in the SFN mode in the D of sub-district, then, UE reads the merged MCCH in the MMSA, and promptly the 3rd MBMS control channel is known professional 3 control informations, according to these control informations, obtain business datum by MTCH corresponding among the D of sub-district.
