多播广播单频网子帧分配的方法、基站及系统Method, base station and system for multicast broadcast single frequency network subframe allocation

技术领域technical field

本发明涉及无线通信领域，尤其涉及一种多播广播单频网(MBSFN)子帧分配的方法、基站及系统。The invention relates to the field of wireless communication, in particular to a method, a base station and a system for allocating multicast broadcast single frequency network (MBSFN) subframes.

背景技术Background technique

单频网传输指的是网络向多个用户发送相同数据的传输模式，引入以单频网传输为基础的MBMS(Multimedia Broadcast Multicast Service，多媒体广播多播业务)是为了实现网络资源共享，以尽可能少的资源实现对尽可能多的具有相同需求的多媒体用户的服务。Single frequency network transmission refers to the transmission mode in which the network sends the same data to multiple users. The introduction of MBMS (Multimedia Broadcast Multicast Service) based on single frequency network transmission is to realize network resource sharing and maximize Serving as many multimedia users as possible with the same needs can be achieved with as few resources as possible.

在3GPP(3rd Generation Partnership Project，第三代移动通信标准化合作项目)系统中，MB SFN(Multicast/Broadcast Single Frequency Network，多播广播单频网)传输是MBMS业务传输的主要方式，即多个基站(发射点)在相同的时频资源块上发送相同的数据，从而使用户终端获得良好的合并分集增益。MBSFN有两种传输模式，一种是专门用于MBMS数据的传输模式，一种是和单播数据混合传输的模式。在后一种传输模式下，单播/多播业务的复用方式是时分复用，即在同一个子帧中不能既传输单播数据又传输多播广播数据，采用单频网模式的多播广播数据只能在MBSFN子帧中传输。目前MBSFN子帧的分配模式均采用宏、微两级分配的模式，如图1所示，宏分配指示每320毫秒的分配周期内哪些无线帧中包含MBSFN子帧，微分配指示每10毫秒的无线帧中用于MBMS业务传输的子帧。In the 3GPP (3rd Generation Partnership Project, third-generation mobile communication standardization cooperation project) system, MB SFN (Multicast/Broadcast Single Frequency Network, multicast broadcast single frequency network) transmission is the main mode of MBMS service transmission, that is, multiple base stations (Transmission point) Send the same data on the same time-frequency resource block, so that the user terminal can obtain good combining diversity gain. MBSFN has two transmission modes, one is a transmission mode dedicated to MBMS data, and the other is a mixed transmission mode with unicast data. In the latter transmission mode, the multiplexing method of unicast/multicast services is time-division multiplexing, that is, both unicast data and multicast broadcast data cannot be transmitted in the same subframe, and multicast in single frequency network mode is adopted. Broadcast data can only be transmitted in MBSFN subframes. At present, the allocation mode of MBSFN subframes adopts the two-level allocation mode of macro and micro. As shown in Figure 1, the macro allocation indicates which wireless frames contain MBSFN subframes in each 320 ms allocation period, and the micro allocation indicates which radio frames contain MBSFN sub frames every 10 ms. A subframe used for MBMS service transmission in a radio frame.

虽然3GPP R8协议规定了MBSFN子帧的存在，但是R8用户并不支持MBSFN子帧的使用；因此，在3GPP R9和/或R10系统中出现的很多新的功能，比如Type1中继(Relay)、高阶多输入多输出技术(High Order-Multi Input MultiOutput，HO-MIMO)、协作多点传输(Coordinated Multi-Point transmission，CoMP)、在FDD(Frequency Division Duplex，频分双工)下行载波上承载监听导频符号(Sounding Reference Symbol，SRS)以及系统定位(Position)等等，都可以通过R8系统中已有的MBSFN子帧来进行传输，即可以在MBSFN子帧中(除了前1-2个OFDM符号)承载任何R8用户不能识别的新功能。Although the 3GPP R8 protocol stipulates the existence of MBSFN subframes, R8 users do not support the use of MBSFN subframes; therefore, many new functions appearing in 3GPP R9 and/or R10 systems, such as Type1 relay (Relay), High Order-Multi Input Multi Output technology (High Order-Multi Input Multi Output, HO-MIMO), coordinated multi-point transmission (Coordinated Multi-Point transmission, CoMP), bearer on FDD (Frequency Division Duplex, Frequency Division Duplex) downlink carrier Listening reference symbols (Sounding Reference Symbol, SRS) and system positioning (Position), etc., can be transmitted through the existing MBSFN subframes in the R8 system, that is, in the MBSFN subframes (except the first 1-2 OFDM symbols) carry new functions that cannot be recognized by any R8 users.

在实现上述MBSFN子帧两级分配的过程中，发明人发现现有技术中至少存在如下问题：In the process of realizing the above-mentioned two-level allocation of MBSFN subframes, the inventors have found that at least the following problems exist in the prior art:

如果一个信令中的多个MBSFN子帧分别承载了不同的新功能，而现有的3GPP系统在进行周期分配的时候为所有新功能对应的MBSFN子帧分配的宏分配周期都是统一设置的，那么对于MBSFN子帧需求较大的功能来说，偏大的宏分配周期设置会造成资源分配不足；而对于MBSFN子帧需求较小的功能来说，偏小的宏分配周期设置会造成资源分配过量。If multiple MBSFN subframes in one signaling carry different new functions respectively, and the existing 3GPP system allocates the macro allocation period for the MBSFN subframes corresponding to all new functions when performing period allocation, it is set uniformly , then for a function with a large demand for MBSFN subframes, a large macro allocation period setting will cause insufficient resource allocation; and for a function with a small MBSFN subframe demand, a small macro allocation period setting will cause resource allocation. Overdispensing.

具体实施方式Detailed ways

下面结合附图对本发明实施例提供的多播广播单频网(MBSFN)子帧分配的方法、基站及系统进行详细描述。The method, base station and system for allocating multicast broadcast single frequency network (MBSFN) subframes provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

在3GPP系统中，MBSFN子帧的分配模式采用宏、微两级分配的方式；具体地，用于指示两级分配的SIB2(System Information Block，系统信息块)信令消息格式如下所示：In the 3GPP system, the allocation mode of the MBSFN subframe adopts the macro and micro two-level allocation; specifically, the SIB2 (System Information Block, system information block) signaling message format used to indicate the two-level allocation is as follows:

    MB SFN-SubframeConfiguration::＝SEQUENCE(SIZE(1..maxMB SFN-Allocations))OFMB SFN-SubframeConfiguration::＝SEQUENCE(SIZE(1..maxMB SFN-Allocations))OF

SEQUENCE{SEQUENCE{

        radioframeAllocationPeriod ENUMERATED{n1，n2，n4，n8，n16，n32}，  radioframeAllocationPeriod ENUMERATED {n1, n2, n4, n8, n16, n32},

        radioframeAllocationOffset  INTEGER(0..7)，radioframeAllocationOffset INTEGER(0..7),

        subframeAllocation    CHOICE{SubframeAllocation CHOICE{

            oneFrame    BIT STRING(SIZE(6))，oneFrame oneFrame BIT STRING(SIZE(6)),

            fourFrames    BIT STRING(SIZE(24))}fourFrames BIT STRING(SIZE(24))}

        }}

其中，maxMBSFN-Allocation代表MBSFN子帧的最大分配次数，因此MBSFN子帧分配配置可以有maxMBSFN-Allocations种，maxMBSFN-Allocations的最大值为8，且每种分配不能出现MBSFN子帧重合；Among them, maxMBSFN-Allocation represents the maximum number of allocations of MBSFN subframes, so MBSFN subframe allocation configurations can have maxMBSFN-Allocations, the maximum value of maxMBSFN-Allocations is 8, and each allocation cannot overlap MBSFN subframes;

radioframeAllocationPeriod代表无线帧分配周期，radioframeAllocationOffset代表无线帧分配偏移，它们的配置对应MBSFN子帧的宏分配；radioframeAllocationPeriod represents the radio frame allocation period, radioframeAllocationOffset represents the radio frame allocation offset, and their configuration corresponds to the macro allocation of MBSFN subframes;

subframeAllocation代表子帧分配，它的配置对应MBSFN子帧的微分配；subframeAllocation represents subframe allocation, and its configuration corresponds to the micro-allocation of MBSFN subframes;

从上面的信令消息格式可以看出，该信令结构并不能对MBSFN子帧所承载的功能进行区分。为解决这一问题，现有的MBSFN子帧功能区分方法企图在一个MBSFN子帧分配配置的基础上对每个MBSFN子帧的功能进行区分，这无疑将所有MBSFN子帧功能分配的宏分配周期设置成一样，如果不能根据不同的功能进行针对性的宏周期设置，将会造成特定功能需求的MBSFN子帧资源分配不足或者分配过量的情况。It can be seen from the above signaling message format that the signaling structure cannot distinguish the functions carried by the MBSFN subframe. In order to solve this problem, the existing methods for distinguishing MBSFN subframe functions attempt to distinguish the functions of each MBSFN subframe on the basis of an MBSFN subframe allocation configuration, which will undoubtedly reduce the macro allocation period of all MBSFN subframe function allocations. If the settings are the same, if targeted macrocycle settings cannot be made according to different functions, it will result in insufficient or excessive allocation of MBSFN subframe resources required by specific functions.

为了能够实现在3GPP系统中，根据业务需求对不同功能对应的MBSFN子帧资源进行灵活的分配，本发明实施例提供了一种多播广播单频网子帧分配的方法、基站及系统。In order to implement flexible allocation of MBSFN subframe resources corresponding to different functions in the 3GPP system according to service requirements, embodiments of the present invention provide a method, base station and system for allocating MBSFN subframes.

实施例一：Embodiment one:

如图2所示，本实施例提供的多播广播单频网子帧分配的方法，包括如下步骤：As shown in Figure 2, the method for multicast broadcast single frequency network subframe allocation provided by this embodiment includes the following steps:

步骤201、接收多播协调实体(MCE，Multicast Coordinated Entity)发送的承载MBMS业务的MBSFN子帧的分配信息。Step 201: Receive allocation information of MBSFN subframes carrying MBMS services sent by a Multicast Coordinated Entity (MCE, Multicast Coordinated Entity).

步骤202、为需要通过MBSFN子帧来承载的其它业务功能分别分配MBSFN子帧，并且对所述其它业务功能中每种业务功能对应的MBSFN子帧的宏分配周期进行独立设置。Step 202: Allocate MBSFN subframes for other service functions that need to be carried by MBSFN subframes, and independently set the macro allocation period of the MBSFN subframes corresponding to each service function in the other service functions.

其中，所述其它业务功能包括3GPP R9和/或R10系统中新引入的、除了承载MBMS传输业务之外的Type1relay、CoMP、HO-MIMO、Position以及在下行载波上承载的监听导频符号SRS等功能中的一种或者几种。Wherein, the other service functions include newly introduced in 3GPP R9 and/or R10 systems, Type 1 relay, CoMP, HO-MIMO, Position and monitoring pilot symbol SRS carried on the downlink carrier in addition to carrying MBMS transmission services, etc. one or more of the functions.

要想对承载不同功能的MBSFN子帧对应的宏分配周期进行独立设置，首先需要在MBSFN子帧分配信令中添加N个比特用以指示MBSFN子帧所承载的功能；这样R9、R10用户在接收到MBSFN子帧分配信令后，也可以根据其承载的功能对该MBSFN子帧进行相应的处理。In order to independently set the macro allocation period corresponding to the MBSFN subframe carrying different functions, it is first necessary to add N bits to the MBSFN subframe allocation signaling to indicate the functions carried by the MBSFN subframe; After receiving the MBSFN subframe allocation signaling, the MBSFN subframe may also be processed accordingly according to the functions carried by it.

假设MBSFN子帧总共对应着M种功能，那么M与N满足如下关系：2^N-1＜M≤2^N。Assuming that MBSFN subframes correspond to M types of functions in total, then M and N satisfy the following relationship: 2^N-1 <M≤2^N .

例如，当前3GPP R9、R10系统新引入的、而R8用户无法识别的新功能有单频网数据传输(在本发明实施例中指MBMS数据传输)、Type1relay、CoMP、HO-MIMO、Position以及在下行载波上承载的监听导频符号SRS；要对上述6种新功能加以区分，就需要在MBSFN子帧分配信令中添加N＝3个比特来携带功能指示信息。具体地，可以通过表1中描述的形式来对各个功能进行区分。For example, the new functions newly introduced by the current 3GPP R9 and R10 systems that cannot be recognized by R8 users include single frequency network data transmission (referred to as MBMS data transmission in the embodiment of the present invention), Type1relay, CoMP, HO-MIMO, Position and downlink The monitoring pilot symbol SRS carried on the carrier; to distinguish the above six new functions, it is necessary to add N=3 bits to carry function indication information in the MBSFN subframe allocation signaling. Specifically, various functions can be distinguished by the forms described in Table 1.

表1Table 1

  N＝3时的功能指示信息(二进制)Function indication information when N=3 (binary) MBSFN子帧承载的功能Functions carried by MBSFN subframes  000000 单频网数据传输Single frequency network data transmission  001001 Type1RelayType1Relay  010010 CoMPCoMP  011011 HO-MIMOHO-MIMO  100100 Positionposition  101101 在下行载波上承载的监听导频符号SRSListening pilot symbol SRS carried on the downlink carrier  110110 保留 reserve  111111 保留 reserve

上述6种新功能与功能指示信息的编码之间的映射关系，是网络侧和用户终端事先约定的，这样用户终端在接收到MBSFN子帧分配信令后即可通过其中包含的功能指示信息判断出不同MBSFN子帧所承载的功能。The mapping relationship between the above six new functions and the coding of the function indication information is agreed in advance between the network side and the user terminal, so that the user terminal can judge the information based on the function indication information contained in it after receiving the MBSFN subframe allocation signaling. functions carried by different MBSFN subframes.

表1所示的情况只是本实施例中的一个具体实例，MBSFN子帧所承载的功能与功能指示信息的编码之间的映射关系还可以根据具体情况进行调整。比如，如果R9和/或R10用户只需要应用到上述新功能中的4种的话，则只需要在MBSFN子帧分配信令中添加N＝2个比特来携带功能指示信息，如表2所示。The situation shown in Table 1 is just a specific example in this embodiment, and the mapping relationship between the function carried by the MBSFN subframe and the coding of the function indication information can also be adjusted according to the specific situation. For example, if R9 and/or R10 users only need to apply four of the above new functions, they only need to add N=2 bits to the MBSFN subframe allocation signaling to carry function indication information, as shown in Table 2 .

表2Table 2

  N＝2时的功能指示信息(二进制)Function indication information when N=2 (binary)  MBSFN子帧承载的功能Functions carried by MBSFN subframes  0000  单频网数据传输Single frequency network data transmission  0101  Type1RelayType1Relay

  1010  CoMPCoMP  1111  HO-MIMOHO-MIMO

由于MBSFN子帧的一个用途必须是用于单频网数据传输，因此MBSFN子帧用于单频网数据传输的功能总是被保留；Type1 Relay技术也是需要在MBSFN上传输以获得对R8用户的后向兼容性因此通过MBSFN子帧实现Type1 Relay技术的功能也被保留；对于其余的几种新功能，只是有可能采用MBSFN子帧传输的方式。因此，在N＝2的时候，MBSFN子帧可承载的功能除了表2所示情况之外，还可以是同时承载单频网数据传输和Type1Relay，以及CoMP、HO-MIMO、Position、在下行载波上承载的监听导频符号SRS中的一种或两种功能。至于每项功能所对应的功能指示信息的具体编码，也不限定于表2中所列举的情况，而是可以根据具体需求进行分配。Since one of the uses of MBSFN subframes must be for single frequency network data transmission, the function of MBSFN subframes for single frequency network data transmission is always reserved; Type1 Relay technology also needs to be transmitted on MBSFN to obtain R8 users For backward compatibility, the function of implementing Type 1 Relay technology through MBSFN subframes is also retained; for the remaining several new functions, it is only possible to use MBSFN subframe transmission. Therefore, when N=2, in addition to the functions shown in Table 2, the MBSFN subframe can also carry SFN data transmission and Type1Relay, as well as CoMP, HO-MIMO, Position, and downlink carrier One or both of the functions in the monitoring pilot symbol SRS carried on the SRS. As for the specific coding of the function indication information corresponding to each function, it is not limited to the cases listed in Table 2, but can be allocated according to specific requirements.

在N＝1的时候，MBSFN子帧仅承载单频网数据传输和Type1Relay这两项功能，其分别对应的功能指示信息的编码可以如表3所示，当然也可以在网络侧和用户终端的约定下将这两项功能对应的编码调换。When N=1, the MBSFN subframe only carries the two functions of single frequency network data transmission and Type1Relay. It is agreed to exchange the codes corresponding to these two functions.

表3table 3

在确定了在MBSFN子帧分配信令中如何指示功能信息之后，就可以根据具体的功能而针对性地为承载某项功能的MBSFN子帧进行宏分配周期设置，具体实现方式可以有以下三种：After determining how to indicate the function information in the MBSFN subframe allocation signaling, you can set the macro allocation period for the MBSFN subframe carrying a certain function according to the specific function. The specific implementation methods can be as follows :

第一种方式：The first way:

将用于指示MBSFN子帧所承载功能的N比特置于MBSFN子帧分配信令中每个配置序列的前端；Place the N bits used to indicate the functions carried by the MBSFN subframe at the front end of each configuration sequence in the MBSFN subframe allocation signaling;

由于MBSFN子帧分配机制的配置列表最大能够支持8种不同的配置，而且每个配置序列中都包含有MBSFN子帧所承载的功能指示信息因此可以通过为MBSFN子帧分配信令中不同的配置序列设置不同的宏分配周期来实现对不同功能对应的宏分配周期的设置。具体地，用于指示两级分配的SIB2信令消息格式如下所示：Since the configuration list of the MBSFN subframe allocation mechanism can support a maximum of 8 different configurations, and each configuration sequence contains the function indication information carried by the MBSFN subframe, it can be assigned different configurations in the signaling for the MBSFN subframe Different macro allocation periods are set in sequence to realize the setting of macro allocation periods corresponding to different functions. Specifically, the format of the SIB2 signaling message used to indicate two-level allocation is as follows:

    MBSFN-SubframeConfigList::＝SEQUENCE(SIZE(1..maxMBSFN-Allocations))OFMBSFN-SubframeConfigList::＝SEQUENCE(SIZE(1..maxMBSFN-Allocations))OF

MBSFN-SubframeConfigMBSFN-SubframeConfig

    MBSFN-SubframeConfig::＝SEQUENCE{MBSFN-SubframeConfig::＝SEQUENCE{

        radioframe Usage Type    BIT STRING(SIZE(N))，radioframe Usage Type BIT STRING(SIZE(N)),

        radioframeAllocationPeriod  ENUMERATED{n1，n2，n4，n8，n16，n32}，  radioframeAllocationPeriod ENUMERATED {n1, n2, n4, n8, n16, n32},

        radioframeAllocationOffset  INTEGER(0..7)，radioframeAllocationOffset INTEGER(0..7),

        subframeAllocation    CHOICE{SubframeAllocation CHOICE{

            oneFrame    BIT STRING(SIZE(6))，oneFrame oneFrame BIT STRING(SIZE(6)),

            fourFrames    BIT STRING(SIZE(24))}fourFrames BIT STRING(SIZE(24))}

        }}

其中，radioframeUsageType部分就是用于指示MBSFN子帧所承载的功能，功能指示信息的编码占用N个比特；此时radioframeAllocationPeriod部分所描述的就是针对具体功能的宏分配周期。Among them, the radioframeUsageType part is used to indicate the function carried by the MBSFN subframe, and the encoding of the function indication information occupies N bits; at this time, the radioframeAllocationPeriod part describes the macro allocation period for the specific function.

第二种方式：The second way:

将用于指示MBSFN子帧所承载功能的编码置于MBSFN子帧分配信令中所有配置序列之后；Place the code used to indicate the functions carried by the MBSFN subframe after all configuration sequences in the MBSFN subframe allocation signaling;

由于MBSFN子帧分配机制的配置列表能够支持maxMBSFN-Allocations种不同的配置，而maxMBSFN-Allocations的最大值为8，因此可以通过为MBSFN子帧分配信令中不同的配置序列设置不同的宏分配周期来实现对不同功能对应的宏分配周期的设置，而每个配置序列所对应的功能由位于所有配置序列之后的N*maxMBSFN-Allocations个比特来指示。具体地，用于指示两级分配的SIB2信令消息格式如下所示：Since the configuration list of the MBSFN subframe allocation mechanism can support maxMBSFN-Allocations different configurations, and the maximum value of maxMBSFN-Allocations is 8, different macro allocation periods can be set for different configuration sequences in the MBSFN subframe allocation signaling To implement the setting of the macro allocation period corresponding to different functions, and the function corresponding to each configuration sequence is indicated by N*maxMBSFN-Allocations bits after all configuration sequences. Specifically, the format of the SIB2 signaling message used to indicate two-level allocation is as follows:

    MBSFN-SubframeConfigList::＝SEQUENCE(SIZE(1..maxMBSFN-Allocations))MBSFN-SubframeConfigList::＝SEQUENCE(SIZE(1..maxMBSFN-Allocations))

OF MBSFN-SubframeConfigOF MBSFN-SubframeConfig

    MBSFN-SubframeConfig::＝SEQUENCE{MBSFN-SubframeConfig::＝SEQUENCE{

        radioframeAllocationPeriod    ENUMERATED{n 1，n2，n4，n8，n 16，n32}，radioframeAllocationPeriod ENUMERATED{n 1, n2, n4, n8, n 16, n32},

        radioframeAllocationOffset    INTEGER(0..7)，radioframeAllocationOffset INTEGER(0..7),

        subframeAllocation    CHOICE{SubframeAllocation CHOICE{

            oneFrame    BIT STRING(SIZE(6))，oneFrame oneFrame BIT STRING(SIZE(6)),

            fourFrames    BIT STRING(SIZE(24))}fourFrames BIT STRING(SIZE(24))}

        }}

    radioframe UsageType    BIT STRING(SIZE(N*maxMBSFN-Allocations))radioframe UsageType BIT STRING(SIZE(N*maxMBSFN-Allocations))

其中，radioframeUsageType部分就是用于指示MBSFN子帧所承载的功能，功能指示信息的编码占用N*maxMBSFN-Allocations个比特，其中，第一个N比特对应第一个配置序列，用于指示第一个配置序列中MBSFN子帧所承载的功能，第二个N比特对应第二个配置序列，其它依次类推；此时radioframeAllocationPeriod部分所描述的就是针对每个配置序列承载的具体功能的宏分配周期。Among them, the radioframeUsageType part is used to indicate the functions carried by the MBSFN subframe, and the encoding of the function indication information occupies N*maxMBSFN-Allocations bits, where the first N bits correspond to the first configuration sequence and are used to indicate the first The function carried by the MBSFN subframe in the configuration sequence, the second N bit corresponds to the second configuration sequence, and so on; at this time, the radioframeAllocationPeriod part describes the macro allocation period for the specific function carried by each configuration sequence.

第三种方式：The third way:

将具有相同宏分配周期的多个功能所对应的MBSFN子帧聚合在同一个MBSFN子帧分配的配置方案中，然后将用于指示MBSFN子帧所承载功能的编码置于MBSFN子帧分配信令中这多个功能对应的配置序列之后；Aggregate the MBSFN subframes corresponding to multiple functions with the same macro allocation period into the same MBSFN subframe allocation configuration scheme, and then put the code used to indicate the functions carried by the MBSFN subframe in the MBSFN subframe allocation signaling After the configuration sequence corresponding to these multiple functions;

对于该MBSFN子帧分配设置中subframeAllocation设置为1的比特位进行功能区分，即为subframeAllocation设置为1的每个比特位添加N比特的功能指示信息；该方案的MBSFN子帧分配的SIB2信令消息格式如下所示，其中，Ki为第i个MBSFN子帧分配设置中subframe Allocation设置为1的比特数量：In the MBSFN subframe allocation setting, the subframeAllocation is set to 1 for functional distinction, that is, N-bit function indication information is added for each bit of subframeAllocation set to 1; the SIB2 signaling message of the MBSFN subframe allocation of this scheme The format is as follows, where Ki is the number of bits with subframe Allocation set to 1 in the i-th MBSFN subframe allocation settings:

    MBSFN-SubframeConfigList::＝SEQUENCE(SIZE(1..maxMBSFN-Allocations))MBSFN-SubframeConfigList::＝SEQUENCE(SIZE(1..maxMBSFN-Allocations))

实施例二：Embodiment two:

如图3所示，本实施例提供的多播广播单频网子帧分配的方法，包括如下步骤：As shown in Figure 3, the method for multicast broadcast single frequency network subframe allocation provided by this embodiment includes the following steps:

步骤301、基站(eNodeB，eNB)通过M2接口向MCE(多播协调实体)上报除MBMS传输之外的其它业务功能对应的MBSFN子帧需求信息。Step 301, the base station (eNodeB, eNB) reports the MBSFN subframe requirement information corresponding to other service functions except MBMS transmission to the MCE (Multicast Coordination Entity) through the M2 interface.

如果由于单播业务的QoS(Quality of Service，网络服务质量)限制等原因而需要MCE在分配用于MBMS传输的MBSFN子帧时考虑到该eNB对于MBSFN子帧所承载的其它功能的需求，那么就需要eNB首先估计出本小区用于Un传输的MBSFN子帧数量、以及其它功能，比如Position、HO-MIMO等，对于MBSFN子帧的使用需求，然后将估计出的MBSFN子帧需求信息上报给MCE。If due to QoS (Quality of Service, network service quality) restrictions of unicast services, etc., the MCE needs to consider the eNB's requirements for other functions carried by the MBSFN subframe when allocating the MBSFN subframe for MBMS transmission, then It is necessary for the eNB to first estimate the number of MBSFN subframes used for Un transmission in the cell, as well as other functions, such as Position, HO-MIMO, etc., for the use of MBSFN subframes, and then report the estimated MBSFN subframe demand information to MCE.

步骤302、MBMS网关将用于MBMS传输的MBSFN子帧需求信息发送给MCE。Step 302, the MBMS gateway sends the MBSFN subframe requirement information for MBMS transmission to the MCE.

步骤303、MCE根据接收到的MBSFN子帧需求信息为eNB分配用于MBMS传输的MBSFN子帧，并进行宏、微两级分配设置。Step 303 , the MCE allocates MBSFN subframes for MBMS transmission to the eNB according to the received MBSFN subframe requirement information, and performs macro and micro level allocation settings.

MCE收到eNB和MBMS网关发送的MBSFN子帧需求信息后，遵循如下原则进行MBSFN子帧的分配：在满足MBMS业务基本QoS需求的前提下，折衷考虑各个eNB的其它功能相应的MBSFN子帧需求，从而使得整体MBSFN子帧分配最优。起码eNB上报的MBSFN子帧需求信息对于选择4个radioframe或者1个radioframe作为微分配的单元是有影响的。After receiving the MBSFN subframe requirement information sent by the eNB and MBMS gateway, the MCE allocates the MBSFN subframe according to the following principles: on the premise of meeting the basic QoS requirements of the MBMS service, compromise the MBSFN subframe requirements corresponding to other functions of each eNB , so that the overall MBSFN subframe allocation is optimal. At least the MBSFN subframe requirement information reported by the eNB has an impact on the selection of 4 radioframes or 1 radioframe as the micro-allocation unit.

步骤304、MCE通过M2接口向eNB发送承载MBMS传输业务的MBSFN子帧分配信令。In step 304, the MCE sends the MBSFN subframe allocation signaling carrying the MBMS transmission service to the eNB through the M2 interface.

步骤305、eNB为MBMS传输以外的其它业务功能分别分配MBSFN子帧，且对所述其它业务功能中每种业务功能对应的MBSFN子帧的宏、微分配模式进行独立设置。In step 305, the eNB allocates MBSFN subframes for other service functions other than MBMS transmission, and independently sets the macro and micro allocation modes of the MBSFN subframes corresponding to each service function in the other service functions.

所有业务功能对应的MBSFN子帧分配信令均采用两级分配的SIB2信令消息格式，其具体实现方式与实施例一中相同，此处不再赘述。The MBSFN subframe allocation signaling corresponding to all service functions adopts the SIB2 signaling message format of two-level allocation, and its specific implementation method is the same as that in Embodiment 1, and will not be repeated here.

步骤306、eNB将承载MBMS传输业务以及其它业务功能的MBSFN子帧的分配信息发送给用户终端(UE，User Equipment)。In step 306, the eNB sends the allocation information of the MBSFN subframe carrying the MBMS transmission service and other service functions to the user equipment (UE, User Equipment).

UE接收到所述MBSFN子帧的分配信息后，可以根据其中携带的功能指示信息对该MBSFN子帧进行相应的处理。After receiving the allocation information of the MBSFN subframe, the UE may perform corresponding processing on the MBSFN subframe according to the function indication information carried therein.

在本实施例中，步骤301和步骤302并不限定它们之间的执行顺序，步骤301和步骤302可以同步执行，也可以按不同的次序先后执行。In this embodiment, step 301 and step 302 do not limit their execution order, and step 301 and step 302 may be executed synchronously, or may be executed successively in different orders.

在不需要基站上报除MBMS传输之外的其它业务功能对应的MBSFN子帧需求信息的情况下，步骤301可以省略，此时进行MBSFN子帧分配的过程与实施例一基本相同，此处不再详细描述。In the case that the base station does not need to report the MBSFN subframe requirement information corresponding to other service functions except MBMS transmission, step 301 can be omitted. At this time, the process of MBSFN subframe allocation is basically the same as that in Embodiment 1, and will not be repeated here. A detailed description.
