Embodiment
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.
The present invention has provided in the MBMS service bearer mode conversion process method about the configuration and the transmission of translates it; Translates it among the present invention sends to UE by network side; Professional transmission (or carrying) mode of the MBMS that is used for notifying this UE receiving will transform the information of (or receive mode of the MBMS business that is described as being used for notifying this UE to change and is receiving from the angle of receiving terminal); Comprise the transformation time information that concrete generation transforms in the translates it simultaneously, and auxiliary UE sets up the information that receives preparation under new send mode.The optional translates it of the present invention comprises content as shown in Figure 2, below the configuration of translates it is described in detail.
Wherein, the purpose of transformation time information is to be used for informing this UE, and what carries out the mode that receives this MBMS business constantly needs to transform.Also can be as being the moment that network side is carried out new send mode.The particular content of transformation time information is for describing the conversion that will carry out receive mode when how long this UE also remains, and the time point of conversion receive mode deducts the time point of network side for this UE transmission translates it when promptly equaling network side remaining time and need transform the UE configuration of receive mode for all.Be about to past tense the remaining time of in the transformation time information of this UE, describing, i.e. when the transformation time point of network side configuration arrived, UE carried out new receive mode.The description unit of remaining time can adopt radio frames, for example describes 15 radio frames of residue, and a radio frames length is 10ms.Certainly; Transformation time information particular content can also adopt other forms; As directly be described as taking place the frame number of the corresponding radio frames of time point that receive mode transforms; Be the frame number that to know each radio frames at present, so when the corresponding radio frames arrival of the radio frames frame number of describing in the transformation time information, UE then carries out the conversion of receive mode according to agreement UE.The concrete of transformation time information confirms that mode does; Network side confirms that at first this MBMS business is converted into the unified transformation time point of MBSFN send mode from the PTP send mode; And then begin to be its transmission translates it for needs carry out UE that receive mode the transforms DCCH through this UE; This moment, network side can confirm which time point to send translates it for this UE at, and network side can be the content configuration of the transformation time information in the translates it that above-mentioned unified transformation time point deducts the difference of sending the time point gained of translates it into this UE just.Receive the translates it of network side transmission as UE after; Therefrom obtain in the transformation time information amount remaining time; UE is that starting point picks up counting from the time point that receives this conversion then; Timing length is the size that lefts in time quantum, waits until that timing finishes just to have carried out the time point of conversion receive mode, receives this MBMS business so this UE is converted into the MBSFN mode.The above-mentioned the present invention of being has provided a kind of expression way of preferred transformation time information; But the invention is not restricted to this kind implementation; As long as can express the time that UE transforms receive mode indirectly or directly; For example transformation time information can for example be decided to be 100ms approximately by network side and UE side agreement in advance simultaneously, and promptly UE receives the translates it that network side sends and plays the receive mode that begins to carry out behind the counting 100ms constantly; It is different that carry out the time point that transform for different UE this moment, but network side need consider that the UE of all conversions begins to receive simultaneously under new receive mode.Here after it should be noted that the 100ms of agreement, UE has accomplished the conversion of new receive mode, but UE possibly just can receive MBMS data under the new mode after a while, needs here to wait for that other UE also accomplish the foundation of new transform mode.Transformation time information also can no longer send to UE like this.
Also can comprise the MBSFN area information in the translates it; This information is used to show the MBMS business that is transformed in which MBSFN zone is sent; So that UE in time receives the phase related control information in this MBSFN zone, be convenient to UE and set up the preparation under the new receive mode fast.Concrete MBSFN area information can directly adopt the ID in MBSFN zone to represent, also can adopt the notice indication (notificationIndicator) corresponding with this MBSFN zone to represent.
Also can comprise MBSFN area information tabulation (MBSFN-AreaInfoList) in the translates it; This parameter is the parameter of network side configuration MBSFN area information; Comprise multicast control channel (the Multicast Control Channel in the MBSFN zone in this parameter; MCCH) configuration information is used for describing the modulation and coded system (the Modulation and Coding Scheme of MCCH in those radio frames and subframe appearance and employing; MCS) information, MCCH information are that the MBMS business in this MBSFN zone of UE reception must at first receive.So this parameter of configuration also is to help helping UE to realize setting up fast new receive mode in translates it.
Also can comprise Physical Multicast Channel (Physical Multicast Channel in the translates it; PMCH) information list (PMCH-InfoList); This parameter is to describe the multicast transmission channel of the correspondence of each MBMS business in the MBSFN zone (Multicast Traffic Channel, cycle, subframe position and the MCS information of MTCH) sending.Help UE to realize setting up fast new receive mode.
Also can comprise Temporary Mobile Group Identity (Temporary Mobile Group Identity in the translates it; TMGI) information; This information is transformed the professional corresponding TMGI of MBMS of send mode, need just can confirm concrete which MBMS of reception professional through TMGI information UE.So the TMGI in the translates it is to inform the UE that needs to transform receive mode, it is professional under new mode, should to receive the corresponding MBMS of this TMGI, rather than other MBMS are professional.
Above-mentioned translates it configuration is just accomplished; Can select one of them in these information or a plurality ofly send to UE, mainly consider the send mode of translates it here, need consider the size of signaling consumption in the process of transmitting as translates it; Obvious above-mentioned translates it is many more; Signaling consumption is big more, so, need be at signaling consumption and set up between the receive mode fast and weigh.The present invention provides optimum translates it and comprises transformation time information, MBSFN area information (under the scene that the MBSFN region overlapping covers, using, if covering scene is next does not use in single MBSFN zone) and TMGI.
The send mode of translates it is described below, sends the professional network side state of MBMS, and propose the method for suitable transmission translates it with the state that the PTP mode receives the professional UE of MBMS through analyzing the PTP mode.The PTP mode is sent the MBMS business; Network side must be known Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (the Cell Radio Network Temporary Identifier of this UE; C-RNTI); And send through Physical Downlink Control Channel (PDCCH) scheduling MBMS business datum, be equivalent to network side like this and send the MBMS business datum for this UE in real time; The UE side, UE must be in connection status, and real-time listening PDCCH obtains the schedule information of MBMS business datum.So the present invention comes to send translates it for receiving the professional UE of MBMS with the PTP mode through PDCCH; The concrete Downlink Control Information that passes through a certain agreement among the PDCCH (Downlink Control Information, DCI) form is realized, changes into the bit implication in this DCI form the implication of above-mentioned translates it; The bit number that for example a certain DCI form comprises is n; So n bit divided into groups according to the several different information in the translates it, a transformation time informational needs a bit for example, the MBSFN area information needs b bit; TMGI needs c bit; Note (a+b+c≤n), among the DCI more than bit keep, but do not represent implication.
Consider that the bit number in the DCI form is more limited; So the present invention also proposes to adopt following send mode; Network side is new Radio Resource control (RRC) message of translates it configuration; (Dedicated Control Channel, the UE that DCCH) transforms receive mode to needs sends the translates it of MBMS service bearer mode through DCCH.The benefit that adopts DCCH is that this channel is that this UE is special-purpose, can not have influence on other UE, and DCCH is that each connection status UE possesses, and does not need the network side provisional configuration.What adopt RRC message mainly is in order to carry more translates it, because RRC message is high-level signaling, transmission means has determined it can carry more signaling.Can in translates it, carry more information like this and give UE.
Network side can be many sub-districts coordination entity (Multi-cell/multicast Coordination Entity among this paper; MCE), broadcast multicast service center (Broadcast-Multicast-Service Centre; BMSC), MBMS gateway (MBMS GateWay; MBMS GW), evolution base station (eNB), mobile management entity (Mobility Management Entity; MME) one or more in if a plurality of, need further be judged the mutual of information so between these a plurality of network elements.
Embodiment 1
Present embodiment hypothesis has a MBMS business giving to have with the mode of PTP needs the UE that receives to send, and network side confirmed need to be the professional send mode that transforms of this MBMS, to improve the spectrum efficiency of sending.Further these professional a plurality of sub-districts that belong to of MBMS of sending with the PTP mode of hypothesis all belong to a sub-district in the MBSFN zone.
The network element of hypothesis network side is MCE in the present embodiment; MCE controls each the affiliated base station, sub-district that need carry out the send mode conversion so; And MCE assigns translates it and gives said each relevant base station, and the base station sends to UE to translates it with the DCCH that the PTP mode receives the professional UE of this MBMS through each.Suppose being configured to of translates it in this enforcement: transformation time information, MBSFN area information, TMGI.
Transformation time information adopts describe remaining time, adopts millisecond for describing unit in the present embodiment, for example remains 200ms.Here transformation time information, MBSFN area information, TMGI that the MBMS business after the MCE handle transforms is sent with the MBSFN mode send to relevant base station, and " all UE that need transform transform the time point of receive mode simultaneously " shown in Fig. 1 promptly known in the base station.The dependency basis beginning configuration that stands clear need be the translates it of the UE transmission that transforms; Here because the base station is different for the time point that each UE sends translates it; So the transformation time information value in the translates it of each UE is different; Here need the base station to determine time point to calculate the value of transformation time information, i.e. poor (the taking absolute value) of two time points for this UE transmission translates it according to " all UE that need transform transform the time point of receive mode simultaneously " and the base station of MCE notice.The value of each UE transformation time information is confirmed that by two time points one is the time point that the MBSFN send mode begins, and one is that the base station is the time point that UE sends translates it.In LTE; These time points correspond to subframe rank (sub-frame of LTE is the 1ms duration); Be that UE receives the translates it that send the base station in some subframes, this sub-frame just receives the starting point of translates it for UE, and the time point that sends translates it with network side is identical.After UE receives translates it, need to open timer, countdown; The timing duration is the value of transformation time information; When timer timing end, UE need change receive mode, promptly is converted into from the PTP receive mode and in the MBSFN zone, receives this MBMS business.
MBSFN area information in the translates it, the present invention adopts MBSFN area I D directly to describe.The ID in corresponding MBSFN zone was expressed as mbsfn-AreaId-r9 when the professional employing of the MBMS that is promptly transformed MBSFN mode was sent in LTE, was the value between 0 to 255.
TMGI in the translates it is used for describing the identification information of MBMS business in the MBSFN zone that is transformed, and according to this TMGI, UE just can find the professional transmission positional information of corresponding MBMS, thereby it is professional to receive this MBMS.

According to LTE; This instance hypothesis adopts DCI (Downlink Control Information; Downlink Control Information) the 1C form sends, and further provides transformation time information use 5bit here, and the MBSFN area information uses notice indication description to need 3bit; Because the content of translates it reduces, so need leave the MBMS business that time enough finds that quilt new send mode has under transformed to UE.This moment, UE need retrieve each MBMS business in the MBSFN zone of translates it indication, thereby the MBMS that the PTP mode is sent before finding is professional.This moment, UE confirmed according to transforming temporal information in this MBMS translates it whether this MBMS business is the MBMS business that is receiving before.It is professional to need this moment network side to note can only beginning to send at this time point the MBMS of this conversion.
In PDCCH, send translates it, the time point that the base station of this moment is confirmed is given the radio frames of UE for sending translates it.UE is the frame number that can know each radio frames in real time.PDCCH sends in subframe; A radio frames comprises 10 sub-frame, as long as UE receives translates it in any one subframe in this radio frames, remembers that all this radio frames is a start time point; Thereby the unlatching timer, the value that the timing duration is set is transformation time information begins to countdown.
MBSFN area information, UE just begin to attempt in specifying the MBSFN zone finding that the MBMS that is transformed is professional after receive translates it.
