…
Find to exist based on above-mentioned conclusion analysis, there are some problems in UE when receiving the MBMS business, and it is professional perhaps to be not convenient for UE reception MBMS.
In the system of a multi-carrier polymerizing; Suppose to have 3 component carriers (CC); Be designated as CC1, CC2 and CC3 respectively; Further hypothesis is being used component carrier 2 (Multimedia Broadcast multicast service Single Frequency Network, MBSFN) mode is being sent the MBMS business with the multimedia broadcasting and multicast Single Frequency Network respectively with component carrier 3.Because the component carrier of selecting during the UE access network to insert is at random, so the UE quantity that inserts in 3 component carriers in this system keeps equal basically.Further, equate basically with the UE quantity of 3 component carriers respectively as own Pcell.
Above-mentioned scene is a common scene in the system of multi-carrier polymerizing technology, but there are some problems in above-mentioned scene, according to existing carrier aggregation technology code requirement.Problem is: UE can only receive broadcast system information in the own principal component carrier wave; As shown in Figure 1, further have only when network side is configured to the Scell of this UE to some other component carriers, and after this Scell is activated; Broadcast system information among the Scell that network side just can be activated through this UE of principal component carrier wave forwarding of this UE; According to the code requirement of existing multi-carrier polymerizing technology, only under above-mentioned situation, UE just can receive the broadcast system information among the Scell.And according to the code requirement of existing multi-carrier polymerizing technology, UE can't receive the broadcast system information in the component carrier of the non-Pcell that removes oneself in the multicarrier system and non-Scell.So UE can't receive except that the MBMS in the component carrier of non-Pcell of oneself and non-Scell professional (because UE can not receive the control information of MBMS business in broadcast system information) at all.
And the renewal of the broadcast system information among the Scell of UE is to carry out through the network side deletion and the process of adding this Scell.If the MBMS that UE is receiving among the Scell is professional, network side has been deleted Scell suddenly so, must cause UE to receive the professional interruption of MBMS so.If UE monitors interested in the non-principal component carrier wave and do not begin the professional beginning of MBMS of sending as yet in addition, in order to let UE better receive the MBMS business, this also is to need the problem that solves.
Provide among the present invention based on the existing standard of above-mentioned multi-carrier polymerizing technology, further professional reception provides solution to MBMS, so that UE receives the MBMS business efficiently.
Summary of the invention
In view of this, the method that main purpose of the present invention is that a kind of user terminal is provided and UE receives business datum in multicarrier system is used for solving UE and can't receives the professional technical problem of MBMS in the non-principal component carrier wave of multicarrier system.
For achieving the above object, technical scheme of the present invention is achieved in that
Receive the method for business datum in a kind of multicarrier system, this method comprises:
In carrier aggregation system; When the UE with carrier aggregation ability receives the MBMS business in one or more non-principal component carrier waves; Said UE receives the broadcast system information of component carrier separately through the carrier aggregation ability from said non-principal component carrier wave; And/or Physical Multicast Channel (PMCH), and/or multicast control channel (MCCH), Multicast Channel schedule information (MSI) and multicast transmission channel (MTCH); Perhaps the UE of connection mode receives the broadcast system information of said non-principal component carrier wave through the principal component carrier wave, from said non-principal component carrier wave, receives MCCH, MSI and MTCH through the carrier aggregation ability.
Further, said UE works or resides in the MBMS business that receives in the principal component carrier wave in said one or more non-principal component carrier waves; The auxilliary component carrier (Scell) that said non-principal component carrier wave is UE, perhaps being is non-principal component carrier wave (Pcell) and the non-Scell of UE; Said UE allow to be received in Scell, or other component carriers of non-Pcell and non-Scell in broadcast system information, and/or PMCH, MCCH or MSI.Said Scell is the Scell that activates or is the Scell of deexcitation.
Further, said broadcast system information is system information block 13 (SIB13) to the LTE system.
Further, said UE monitors through the renewal indication information of the broadcast system information in the beep-page message in the said non-principal component carrier wave whether broadcast system information upgrades in the said non-principal component carrier wave.
Further, when the MBMS business in the said non-principal component carrier wave did not begin to send as yet, UE received the MCCH update notification message through the PDCCH Catalog Search zone of the given sub-frame of multi-carrier polymerizing ability from said non-principal component carrier wave.
Further, the UE subframe of aliging with said non-principal component subcarrier time according to the principal component carrier wave is confirmed the arrival opportunity of given sub-frame described in the said non-principal component carrier wave.
Further, said UE receives before the MBMS business in one or more non-principal component carrier waves, and UE is known the MBMS business information in the said non-principal component carrier wave through electronic program guides.
Based on said method, the present invention also proposes a kind of UE, and this UE has the carrier aggregation ability, and in carrier aggregation system, this UE also is used for receiving the MBMS business of one or more non-principal component carrier waves; When the MBMS of said UE in receiving one or more non-principal component carrier waves is professional, from said non-principal component carrier wave, receive the broadcast system information of component carrier separately through the carrier aggregation ability, and/or PMCH, and/or MCCH, MSI and MTCH; Perhaps UE receives the broadcast system information of said non-principal component carrier wave through the principal component carrier wave, from said non-principal component carrier wave, receives MCCH, MSI and MTCH through the carrier aggregation ability.
After adopting mode of the present invention; In the time of can avoiding UE in Scell, to receive the MBMS business; Owing to upgrading the UE that causes, the broadcast system information of Scell in Scell, receives the professional interruption generation of MBMS; In the time of can avoiding UE to receive the MBMS business in the non-principal component carrier wave, need the principal component carrier wave to transmit broadcast system information.Be convenient to monitor when UE is operated in the principal component carrier wave MCCH update notification message in the non-principal component carrier wave.

Embodiment
The present invention is through the existing multi-carrier polymerizing technical specification of labor; Find that wherein professional reception brings some restrictions and inconvenience for MBMS; Find through further analysis; In the formulation process of the standard of existing multi-carrier polymerizing technology, only consider that the demand of unicast service is formulated, help receiving unicast service at multi-carrier aggregation system UE.So above-mentioned standard is unfavorable for the reception that MBMS is professional, and brought loss for the professional reception of MBMS, make UE receive the very inconvenience of MBMS business, why main like this is because unicast service and MBMS business essential different.Unicast service is a point to point service, PTP, is received and is sent by base stations control UE, and UE carries out associative operation according to the signaling of base station; So the base station is a Data Receiving situation of knowing UE in real time, but professional for MBMS, is point-to-multipoint service; Network side sends with broadcast mode, and UE is professional according to the interested MBMS of the hobby selective reception of oneself, because the MBMS business is unidirectional descending; As long as be that UE has the MBMS ability and just can receive; Do not need UE and network side (base station) to carry out alternately, network side does not know that UE is receiving the MBMS business yet, and it is professional not know that more UE is receiving that MBMS.So confirm that according to the business demand of UE clean culture network side is can not satisfy UE to receive the professional demand of MBMS for the scheduling mechanism of UE in the standard of existing multi-carrier polymerizing, it is professional to be unfavorable for that in other words UE receives MBMS.So the present invention, has proposed the professional method of reseptance of MBMS in the multi-carrier polymerizing technology through analyzing the MBMS business features.
Basic thought of the present invention is; In multi-carrier aggregation system; When UE be operated in network side for the own principal component carrier wave that disposes in the time; And UE need receive MBMS in non-principal component carrier wave when professional (suppose UE can know have in the non-principal component carrier wave MBMS is professional to be sent) here; UE utilize carrier aggregation technology directly through the component carrier at the professional place of the MBMS that will receive receive the broadcast system information of this component carrier, thereby in broadcast system information, obtain the MBMS relevant configuration information in the said component carrier, thereby realize continuing on this component carrier, receiving MBMS professional (the MBMS business is to be carried among the PMCH).For example; UE is operated in the principal component carrier wave of oneself; When UE interested for the MBMS business in other component carriers; UE can receive the broadcast system information in this component carrier and further receive in the said component carrier according to the relevant information in the broadcast system information and be carried on Physical Multicast Channel (Physical Multicast Channel through polymerizing power in other component carriers; PMCH) multicast control channel in (Multicast Control Channel, MCCH), the Multicast Channel schedule information (MCHScheduling Information, MSI); Further be received in MTCH (the Multicast Traffic Channel among the PMCH in the said component carrier according to MCCH, MSI information then; The multicast transmission channel), MTCH carries the MBMS business datum, thereby is implemented in the professional reception of MBMS in said other component carriers.
When above-mentioned UE is professional according to the MBMS in the said component carrier that is receiving; UE need monitor the renewal indication information of the broadcast system information in this component carrier beep-page message; Judge according to said renewal indication information whether broadcast system information renewal has taken place in this component carrier; If renewal has taken place; UE then directly receives the broadcast system information after upgrading in this component carrier so, and need not pay close attention in the own principal component carrier wave signaling for this component carrier, and for example whether this component carrier is by deletion or add.Thereby avoided one of problem that the present invention mentions in background technology; Promptly when UE just receives the MBMS business in Scell; Network side is not just receiving the MBMS business owing to know UE in Scell, and this Scell deletion, causes UE to receive the MBMS failure according to existing multi-carrier polymerizing technical specification.Here also solve UE and in Scell, received MBMS when professional; Network side is the problem that UE can't transmit the broadcast system information among the Scell through dedicated signaling; The front had said that network side do not know that whether UE is receiving the MBMS business, transmits the broadcast system information among the said Scell so which UE network side can't confirm as.
Here other component carriers of saying can be the Scell of UE, can be that what to activate also can be deexcitation, also can be in the system neither the Pcell of UE neither UE the component carrier of Scell.This also adopts scheme of the present invention to realize; Promptly when in oneself the principal component carrier wave of UE work; UE uses that to receive MBMS in the component carrier of multi-carrier polymerizing technology non-Pcell and non-Scell in system professional, and concrete receiving course is identical with aforesaid way.
When the existing unicast service of UE has MBMS professional again; If said MBMS business is to be carried among the Scell of UE; UE receives the unicast service continuation and goes execution according to existing multi-carrier polymerizing standard so, and UE receives the MBMS business among the said Scell simultaneously, carries out according to aforesaid way of the present invention.
If UE is operated in the principal component carrier wave; MBMS business for sending in the non-principal component carrier wave in the system is interested; When but this MBMS business did not also begin to send, UE monitored the professional beginning situation of said MBMS through the MCCH update notification message that the multi-carrier polymerizing ability receives in the said non-principal component carrier wave.The MCCH update notification message is to be carried in the Catalog Search zone of PDCCH of given sub-frame; So when UE is operated in the principal component carrier wave; When whether UE need monitor MBMS business in the non-principal component carrier wave and begin, UE used blind check in the PDCCH Catalog Search zone of the given sub-frame of carrier aggregation ability in said non-principal component carrier wave, receives the MCCH update notification message.Given sub-frame is meant the subframe that in the broadcast system information of said non-principal component carrier wave, disposes for the MCCH update notification message.In brief, in multi-carrier aggregation system, when UE receives MBMS among the non-main Pcell when professional, the PDCCH Catalog Search zone that UE can retrieve in the component carrier of non-main Pcell obtains wherein information.The subframe position of correspondence that can be through confirming the principal component carrier wave when above-mentioned UE confirms whether the subframe position of the carrying MCCH update notification message in the said non-principal component carrier wave arrives confirms whether the subframe position that can avoid like this calculating the MCCH update notification message according to said non-principal component carrier wave in the UE snoop procedure arrives.Here utilized that different carrier is the principle of strict alignment in the multicarrier system.
Find that for UE the MBMS service related information in other component carriers provides a kind of mode among the present invention, but the invention is not restricted to this mode, be i.e. the professional distributed intelligence of existing MBMS in UE in this way can the discovery system, carrier information etc.Need be in multicarrier system at electronic program guides (Electronic Service Guide; ESG) frequency point information of the professional corresponding carrier wave of each MBMS of the configuration of demonstration or implicit expression, access information or the like in; After the user selected a certain MBMS business through electronic program guides like this, UE was then directly known the component carrier information at the professional place of said MBMS according to electronic program guides.
For making the object of the invention, technical scheme and advantage clearer, below lift embodiment and with reference to accompanying drawing, to further explain of the present invention.
Embodiment 1
Suppose to have a multi-carrier aggregation system, have 4 component carriers to exist in this system, be designated as CC1, CC2, CC3 and CC4 respectively, suppose that further CC1, CC2 and CC3 are all carrying MBMS business separately, CC4 does not carry the MBMS business.Further the UE in this system of hypothesis is evenly distributed in 4 component carriers, and wherein each component carrier all is the principal component carrier wave of a lot of different UEs.Suppose that UE1 is linked in the system, UE1 has the multi-carrier polymerizing ability, has the MBMS professional ability simultaneously, and the setting network side is that the principal component carrier wave of UE1 configuration is CC1, is CC2 for its configuration Scell again.
As shown in Figure 2, if UE1 for the professional reception interested of a certain MBMS that sends among the CC2, and this MBMS business has begun to send in CC2.According to the present invention; The MBMS that UE1 need receive in the non-principal component carrier wave is professional, and UE1 directly receives broadcast system information by means of the carrier aggregation ability from CC2 so, therefrom obtains the professional relevant configuration information of MBMS among the CC2; MBSFN area information for example; MCCH update notification message positional informations etc. according to the position that these information UE1 can confirm MCCH among the CC2, pass through to receive in the PMCH channel of carrier aggregation ability in CC2 MCCH information then; Further confirm the position of MSI information in the PMCH channel then according to MCCH information; Receive MSI information then, then according to the professional MTCH of interested MBMS in the MSI message pick-up PMCH channel, thus the reception of completion MBMS business datum.UE continue to adopt the multi-carrier polymerizing ability to monitor among the CC2 in the beep-page message renewal indication information about broadcast system information then; Inform that the broadcast system information of CC2 upgrades if find the renewal indication information of said broadcast system information, UE1 then need obtain the broadcast system information of CC2 again so.
Network side need not utilize in the prior art standard professional to realize that UE1 receives MBMS in CC2 through the broadcast system information of in the principal component carrier wave of UE1, transmitting among the ScellCC2; The forwarding mechanism of prior art standard is to know that concrete which UE is receiving the MBMS business; And exactly the professional network side of MBMS is ignorant; Have only when UE has unicast service and MBMS business simultaneously, network side just can be transmitted the broadcast system message of Scell.Send because the business of the MBMS among the CC2 is actual; The MBMS business features is that point is to multiple spot; The UE that much with CC2 is the principal component carrier wave is receiving the MBMS business among the CC2; So the MBMS business among the CC2 can not stop because network side has closed the Scell CC2 of UE1 sending; So by the present invention, UE1 receives MBMS in Scell CC2 professional, can not receive the unlatching of Scell CC2 or the influence of closing; Thereby avoid proposing in the background technology because the closing of Scell (when for example the network side decision is no longer sent unicast data for this UE in this Scell), the principal component carrier wave is no longer transmitted the broadcast system information of Scell and is caused UE1 can not receive the appearance of the situation of MBMS business among the CC2.Also can avoid network side is that UE1 transmits the broadcast system information among the Scell CC2 through the principal component carrier wave of UE1.
Above-mentioned UE1 directly monitors in the beep-page message renewal indication information about the broadcast system information of CC2 by the multi-carrier polymerizing ability in CC2; Thereby find the more new situation of the broadcast system information among the CC2; Thereby avoided because the broadcast system information among the Scell CC2 upgrades, network side is deleted the Scell (reality is exactly the Scell CC2 that has closed UE1) of UE1 and is caused UE1 can not continue to receive the professional situation appearance of MBMS among the CC2.
In addition, though CC2 is the Scell of UE1, if the unicast service of UE1 finishes; Network side possibly closed the Scell CC2 of UE1, and promptly this moment, UE1 and CC2 were neither Pcell, also non-Scell; But according to said method of the present invention, it is professional that UE1 also can realize in CC2, receiving MBMS in this case.Scheduling is sent if UE1 has unicast service in principal component carrier wave CC1 and Scell CC2; UE1 receives the broadcast system information among the Scell CC2 that transmits from the principal component carrier wave so; These broadcast system informations are that UE1 receives unicast service and must receive in Scell CC2; Suppose to have in the broadcast system message of this forwarding UE to receive MBMS necessary information when professional; So under this kind scene, UE1 can receive the broadcast system information of the Scell CC2 that transmits through the principal component carrier wave, in Scell CC2, only receives MCCH, MSI, MTCH through the carrier aggregation ability and gets final product.Can help UE1 to realize power saving like this,, and safeguard that more new capital of the broadcast system information of Scell CC2 is relatively to take electricity because UE1 independently receives the broadcast system information of Scell CC2.
