Embodiment
It is by the following examples and referring to the drawings, right for the object, technical solutions and advantages of the present invention are more clearly understood
The present invention is further described.
The present invention gives in MBMS bearing mode conversion process on convert information configuration and transmission method,
Conversion information in the present invention is to be sent to UE by network side, for notifying the transmission of MBMS that the UE receiving
(or carrying) mode will occur conversion and (or be described as from the angle of receiving terminal for notifying the UE to change the MBMS received
The reception mode of business) information, while convert comprising the specific transformation time information converted in information, and aid in
UE establishes the information for receiving preparation under new sending method.Optional conversion information of the invention includes as shown in Figure 2
Content, the configuration for converting information is described in detail below.
Wherein, the purpose of transformation time information is that what moment, which performs, receives the side of the MBMS for informing the UE
Formula needs to convert.At the time of can also be as being that network side performs new sending method.The particular content of transformation time information is
Describe the UE there remains how long when will perform reception mode conversion, i.e., remaining time be equal to network side for it is in need convert connect
The time point that reception mode is converted while the UE configurations of debit's formula subtracts the time point that network side sends conversion information for the UE.
Remaining time described in the transformation time information of the UE reaches past tense, i.e. the transformation time point of network side configuration
When, UE performs new reception mode.The description unit of remaining time can use radio frames, such as remaining 15 of description is wirelessly
Frame, a wireless frame length is 10ms.Certainly, transformation time information particular content can also use other forms, such as directly retouch
The frame number of radio frames corresponding to the time point converted for generation reception mode is stated, is at present that can know each according to agreement UE
The frame number of radio frames, so when radio frames corresponding to radio frames frame number described in the transformation time information reach, UE is then held
The conversion of row reception mode.The specific determination mode of transformation time information is that network side determines that the MBMS is sent out from PTP first
Send mode to be converted into the unified transformation time point of MBSFN sending methods, then start again to need to carry out reception mode conversion
UE by the DCCH of the UE be its transmission conversion information, now network side can determine be at which time point
The UE sends conversion information, and the content of the transformation time information in conversion information is configured to above-mentioned unification by network side can
Transformation time point subtracts the difference sent for the UE obtained by the time point of conversion information.When UE receives the conversion of network side transmission
After information, remaining time amount in transformation time information is therefrom obtained, then UE opens from the time point for receiving the conversion for starting point
Beginning timing, timing length are the size for lefting in time quantum, when timing terminates the time of namely execution conversion reception mode
Point, so the UE is converted into MBSFN modes and receives the MBMS.Above-mentioned is that The present invention gives a kind of preferred transformation time
The expression way of information, but the invention is not restricted to such a implementation, received as long as UE conversions indirectly or can be expressed directly
The time of mode, such as transformation time information can be arranged in advance simultaneously by network side and UE sides, e.g., from about be set to
Start the reception mode performed from the conversion information moment that 100ms, i.e. UE receive network side transmission after counting 100ms, now
The time point difference of conversion is performed for different UE, but network side needs to consider the UE of all conversions in new reception mode
Under start simultaneously at reception.It is noted herein that after the 100ms of agreement, UE completes the conversion of new reception mode, still
UE may can just receive MBMS data under new paragon later, need to wait other UE also to complete new transform mode here
Foundation.So transformation time information can also be never sent to UE.
MBSFN area informations can be also included in conversion information, the MBMS that the information is used to show to be converted is at which
Individual MBSFN regions are transmitted, and in order to which UE receives the related control information in the MBSFN regions in time, are easy to UE quickly to establish
Preparation under new reception mode.Specific MBSFN area informations can directly use the ID in MBSFN regions to represent,
(notificationIndicator) can be indicated to represent using notice corresponding with the MBSFN regions.
MBSFN area informations list (MBSFN-AreaInfoList) can be also included in conversion information, the parameter is network
Side configures the parameter of MBSFN area informations, and the multicast control channel (Multicast in MBSFN regions is included in the parameter
Control Channel, MCCH) configuration information be used to describing MCCH occurring in those radio frames and subframe and use
Modulation and coded system (Modulation and Coding Scheme, MCS) information, MCCH information is that UE receives the MBSFN
What the MBMS in region must receive first.Realized soon in help UE so configuring the parameter in information is converted and being also advantageous that
New reception mode is found in run-up.
Physical Multicast Channel (Physical Multicast Channel, PMCH) information can also be included by converting in information arranges
Table (PMCH-InfoList), the parameter are to describe the corresponding multicast transmission channel of each MBMS in MBSFN regions
Cycle, subframe position and the MCS information that (Multicast Traffic Channel, MTCH) is sent.UE is contributed to realize quick
Establish new reception mode.
Convert information in can also include Temporary Mobile Group Identity (Temporary Mobile Group Identity,
TMGI) information, the information are to be converted TMGI corresponding to the MBMS of sending method, are assured that by TMGI information UE
Which need that MBMS specifically received.So the TMGI in conversion information, is to inform the UE for needing to convert reception mode,
MBMS corresponding to the TMGI, rather than other MBMSs should be received under new mode.
Above-mentioned conversion information configuration is just completed, and one or more of which can be selected in these information as conversion
Information is sent to UE, is mainly in view of the sending method of conversion information here, is needed in transmission process in view of signaling consumption
Size, it is clear that above-mentioned conversion information is more, and signaling consumption is bigger, it is therefore desirable in signaling consumption and quickly establish reception mode
Between weigh.The present invention, which provides optimal conversion information, includes transformation time information, MBSFN area informations (in MBSFN regions weight
Used under the scene of superimposition lid, if under single MBSFN region overlays scene then without using) and TMGI.
The sending method of the information of description conversion below, the network side state of MBMS is sent by analyzing PTP modes, with
And the method that the UE of MBMS state proposes suitable transmission conversion information is received in a manner of PTP.PTP modes send MBMS
Business, network side must know Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (the Cell Radio Network Temporary of the UE
Identifier, C-RNTI), and MBMS data is dispatched by Physical Downlink Control Channel (PDCCH) and is transmitted, this
Sample sends MBMS data for the UE in real time equivalent to network side；UE sides, UE necessarily be in connection status, monitor in real time
PDCCH obtains the schedule information of MBMS data.So the present invention by PDCCH come to be received in a manner of PTP
The UE of MBMS sends conversion information, specifically passes through the Downlink Control Information (Downlink of a certain agreement in PDCCH
Control Information, DCI) form realizes, the bit implication in the DCI format changed into above-mentioned conversion information
Implication, such as the bit number that includes of a certain DCI format is n, then by n bit according to the several differences converted in information
Information is grouped, such as transformation time information needs a bit, and MBSFN area informations need b bit, and TMGI needs c
Bit, pay attention to (a+b+c≤n), the bit being more than in DCI retains, but does not indicate that implication.
In view of the bit number in DCI format than relatively limited, so the present invention also proposes to use following sending method, net
Network side is new wireless heterogeneous networks (RRC) message of conversion information configuration one, passes through DCCH (Dedicated
Control Channel, DCCH) to need convert reception mode UE send MBMS bearing mode conversion information.Adopt
It is that the channel is that the UE is special with the benefit of DCCH, does not interfere with other UE, DCCH is each
Individual connection status UE possesseds, it is not necessary to network side provisional configuration.Using RRC information primarily to more turns of carrying
Change information, because RRC information is high-level signaling, transmission means determines that it can carry more signalings.It can so turn
Change in information and carry more information to UE.
Network side herein can be multiple cell coordination entity (Multi-cell/multicast Coordination
Entity, MCE), broadcast multicast service center (Broadcast-Multicast-Service Centre, BMSC), MBMS nets
Close (MBMS GateWay, MBMS GW), evolution base station (eNB), mobile management entity (Mobility Management
Entity, MME) in one or more, if multiple, then need further to carry out judgement letter between this multiple network element
The interaction of breath.
Embodiment 1
Present embodiment assumes that there is UE of the MBMS to reception in need in a manner of PTP to send, and net
Network side, which has determined that, to be needed to convert sending method for this MBMS, to improve the spectrum efficiency sent.It is further assumed that
Multiple cells where this MBMS sent in a manner of PTP belong to the cell in a MBSFN region.
The network element that network side is assumed in the present embodiment is MCE, then MCE controls are each to be needed to be transmitted what mode converted
Base station belonging to cell, and MCE assigns conversion information to each associated base stations, base station conversion information by it is each just
UE is sent in the DCCH for the UE that the MBMS is received in a manner of PTP.Matching somebody with somebody for conversion information is assumed in this implementation
It is set to：Transformation time information, MBSFN area informations, TMGI.
Transformation time information is described using remaining time, and millisecond is used in the present embodiment to describe unit, such as remaining
200ms.Here MCE is sent the MBMS after conversion in a manner of MBSFN transformation time information, MBSFN area informations,
TMGI is sent to associated base stations, base station be know shown in Fig. 1 " the UE of conversion in need while convert reception mode
Time point ".Associated base stations are initially configured the conversion information for needing the UE for conversion to send, here because base station is each UE hairs
Send the time point of conversion information different, so the transformation time information value in each UE conversion information is different, here
Need base station according to MCE notify " conversion in need UE and meanwhile convert the time point of reception mode " and base station be determined as this
The time point of UE transmission conversion information calculates the value of transformation time information, i.e., the difference (taking absolute value) at two time points.Often
The value of one UE transformation time information determines by two time points, and one is time point that MBSFN sending methods start,
One is that base station sends the time point for converting information for UE.In LTE, these time points correspond to subframe rank (one of LTE
Subframe is 1ms durations), i.e. UE receives the conversion information of base station transmission in some subframe, and this subframe just receives for UE
To the starting point of conversion information, the time point that conversion information is sent with network side is identical.After UE receives conversion information, need
Timer is opened, is countdowned, the value of a length of transformation time information, terminates when timer during timing, and UE needs to turn
Changing-over debit's formula, i.e., it is converted into from PTP receptions mode in MBSFN regions and receives the MBMS.
The MBSFN area informations in information are converted, the present invention is directly described using MBSFN regions ID.It is converted
The ID in corresponding MBSFN regions, is expressed as mbsfn-AreaId-r9 in LTE when MBMS is sent using MBSFN modes,
It is the value between one 0 to 255.
TMGI in conversion information is identification information for the MBMS for describing to be converted in MBSFN regions, root
According to the TMGI, UE cans find the transmission positional information of corresponding MBMS, so as to receive the MBMS.

If using radio frames to be described for unit, maximum can describe 16 radio frames, i.e. 160ms for order.
According to LTE, this example is assumed to use DCI (Downlink Control Information, Downlink Control Information)
1C forms are sent, and are further provided transformation time information here and used 5bit, and MBSFN area informations are indicated using notice
Description needs 3bit, because the content for converting information is reduced, has sufficient time to find new sender so needing to stay to UE
The MBMS being converted under formula.Now UE needs to retrieve each MBMS industry in the MBSFN regions of conversion information instruction
Business, so as to the MBMS that PTP modes are sent before finding.Now UE is next according to temporal information is converted in MBMS conversion information
Determine whether the MBMS is the MBMS received before.Network side is now needed to pay attention to open at the time point
Originate the MBMS for giving the conversion.
Conversion information is sent in PDCCH, the time point of base station determination now is to send conversion information to the wireless of UE
Frame.UE is the frame number that can know each radio frames in real time.PDCCH is sent in subframe, and a radio frames include 10
Individual subframe, as long as UE receives conversion information in the radio frames in any one subframe, it is initial time all to remember the radio frames
Point, so as to open timer, the value of a length of transformation time information starts to countdown when setting timing.
MBSFN area informations, UE begin to attempt to find quilt in specified MBSFN regions after conversion information is received
The MBMS of conversion.
