背景技术
基于通信的碰撞预警系统，通过利用先进的无线通信技术和新一代信息处理技术，实现车与车、车与路侧基础设施间的实时信息交互，告知彼此目前的状态(包括车辆的位置、速度、加速度、行驶路径)及获知的道路环境信息，协作感知道路危险状况，及时提供多种碰撞预警信息，防止道路交通安全事故的发生，成为当前各国试图解决道路交通安全问题的一种新的思路。
车联网(Vehicle to Everything，V2X)是指通过装载在车辆上的传感器、车载终端及电子标签提供车辆信息，采用各种通信技术实现车与车(Vehicle to Vehicle，V2V)、车与人(Vehicle to Pedestrian，V2P)、车与路(基础设施)(Vehicle to Infrastructure，V2I)互连互通，并在信息网络平台上对信息进行提取、共享等有效利用，对车辆进行有效的管控和提供综合服务，其中，车联网的示意图如图1所示。
相关技术中，采用长期演进(Long Term Evolution，LTE)技术解决基于车联网通信应用的研究。
路边通信单元(Road Side Unit，RSU)以接收车辆请求，保证车辆接入Internet，有网关的功能；此外，它也拥有数据运算、存储、转发的功能。

相关技术中，RSU可通过静止的用户设备(User Equipment，UE)或eNB实现，然而，相关技术中存在因为低版本UE不支持高版本技术，可能造成低版本UE无法接收高版本UE发送的数据，以及基站或发送UE同时可支持高版本技术时，因为不知道接收UE的版本能力，所以无法确定是否可以采用高版本技术功能等问题，导致不同版本UE无法协同工作、业务传输的兼容能力差。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
相关技术中，3GPP正在讨论的LTE V2X技术包括：RSU可通过静止的UE或eNB实现，V2V/V2I/V2P可能通过PC5接口或Uu接口实现，其中PC5接口是指设备到设备D2D的空中接口，Uu接口是指UE到eNB的空中接口。通过PC5口发送V2X业务的系统架构如图2所示：
在3GPP正在研究的LTE V2X课题中，针对UE自主选择资源(模式4-mode4)方式中，UE采用感知(sensing)方式选择所需的PC5接口发送资源；当发生切换(HO-Handover)、无线链路失败(Radio Link Failure，RLF)、改变资源池等情况时，可采用异常(exceptional)资源池。对于V2P中的行人(Pedestrian，P)一般不具备PC5接收的能力，即无法采用感知选择资源。
V2X信息为安全相关信息，一般不允许丢弃；如果发生网络拥塞，需要针对不同的拥塞程度选择相应的无线传输参数，为此，3GPP中采用信道忙率(Channel Busy Ratio，CBR)衡量信道的拥塞程度，CBR定义为在一段时间(一般为100ms)内，资源池中子信道能量超过门限值的比例，其 中子信道能量采用边路-接收信号强度指示(Sidelink-Received Signal Strength Indication，S-RSSI)标识，门限值为事先确定，UE根据网络侧的测量配置测量计算CBR；针对某个给定的CBR，网络侧基于每个V2X优先级(采用基于临近区域的业务(Proximity based Services，PPPP-ProSe)Per-Packet Priority，Prose分组优先级)提供一个映射表，每个表中包含CBR(一般为一个范围)和对应的无线资源参数，UE根据CBR选择对应的无线资源参数。
为了便于描述，本文中V-UE是指Vehicle-UE，P-UE是指Pedestrian-UE。
相关技术中，LTE V2X中针对PC5链路可采用两种资源配置方法：模式mode3和mode4，其中mode3是指基站配置PC5的无线资源，mode4是指UE自主选择PC5的无线资源；mode3和mode4的资源池分别配置，不能重叠。
在3GPP Release-15的eV2X(enhanced V2X)课题中提出了mode3资源和mode4资源共享的研究，以提高PC5资源的利用率。
同时在R15eV2X课题中还提出了一些新的增强技术，如发送分集(Tx diversity)，64正交幅度调制(Quadrature Amplitude Modulation，QAM)，载波聚合CA等。
相关技术中，RSU可通过静止的UE或eNB实现，然而，相关技术中存在因为低版本UE不支持高版本技术，可能造成低版本UE无法接收高版本UE发送的数据，以及基站或发送UE同时可支持高版本技术时，因为不知道接收UE的版本能力，所以无法确定是否可以采用高版本技术功能等问题，导致不同版本UE无法协同工作、业务传输的兼容能力差。
本申请实施例所提供的方法实施例可以在移动终端、计算机终端或者类似的运算装置中执行。以运行在移动终端上为例，图3是本发明实施例的一种业务的发送方法的移动终端的硬件结构框图。如图3所示，移动终端10可以包括一个或多个(图3中仅示出一个)处理器102(处理器102 可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)和配置为存储数据的存储器104，在一实施例中，上述移动终端还可以包括配置为通信功能的传输设备106以及输入输出设备108。本领域普通技术人员可以理解，图3所示的结构仅为示意，其并不对上述移动终端的结构造成限定。例如，移动终端10还可包括比图3中所示更多或者更少的组件，或者具有与图3所示不同的配置。
存储器104可配置为存储计算机程序，例如，应用软件的软件程序以及模块，如本发明实施例中的业务的发送方法对应的计算机程序，处理器102通过运行存储在存储器104内的计算机程序，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器104可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器104可进一步包括相对于处理器102远程设置的存储器，这些远程存储器可以通过网络连接至移动终端10。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置106配置为经由一个网络接收或者发送数据。上述的网络实例可包括移动终端10的通信供应商提供的无线网络。在一个实例中，传输装置106包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输装置106可以为射频(Radio Frequency，RF)模块，其配置为通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于上述移动终端的业务的发送方法，图4是根据本发明实施例的业务的发送方法流程图，如图4所示，该流程包括如下步骤：
步骤S402，确定待发送业务对应的发送技术，其中，该发送技术至少包括：第一发送技术、第二发送技术，该第一发送技术和该第二发送技术 分别对应的接收用户设备UE的版本不同；
步骤S404，确定与该发送技术对应的发送资源，并在确定的发送资源上发送该待发送业务。
在一实施例中，上述业务的发送方法的应用场景包括但并不限于：车联网V2X业务，可穿戴(Wearable)业务，机器类型通信(Machine Type Communication，MTC)，公共安全(Public Safety，PS)通信，物联网(Internet Of Thing，IOT),UE-to-Network relay等。在上述应用场景下，确定待发送业务对应的发送技术，其中，该发送技术至少包括：第一发送技术、第二发送技术，该第一发送技术和该第二发送技术分别对应的接收用户设备UE的版本不同；确定与该发送技术对应的发送资源，并在确定的发送资源上发送该待发送业务。也就是说，通过将发送业务与发送技术对应，使得接收UE可以根据发送技术与自身的版本是否对应来选择性接收业务，进而解决了相关技术中不同版本UE无法协同工作所导致的业务传输的兼容能力较差的问题，达到了提高业务传输的兼容能力的技术效果。
在一实施例中，步骤S402和步骤S404的执行顺序是可以互换的，即可以先执行步骤S404，然后再执行S402。
下面结合示例，对本实施例进行举例说明。
UE应用层通知接入层待发送V2X业务需求，UE接入层或基站根据业务需求确定可采用的发送技术，针对高优先级V2X业务，采用低版本兼容的发送技术。在UE发送的资源配置信息中指示发送的版本信息。
如图5所示包括如下步骤：
步骤S501，UE应用层指示接入层：V2X业务需求信息。
上述UE为发送方UE，上述应用层产生V2X业务，通过应用层和接入层之间的接口向接入层发送V2X业务和V2X业务的需求信息，其中上述需求信息包括以下之一：业务优先级PPPP(Prose Per Packet Priority)，业务可靠性PPPR(Prose Per Packet Reliability)，业务QoS(服务质量，Quality of  Service),业务大小，目标地址等。
上述接入层包括以下之一：层1，层2，层3，分别对应物理层，链路层，RRC层。
步骤S502，UE接入层或基站判断是否需要高版本增强技术发送，如果是，转向步骤S503，否则，转向步骤S504。
如果采用UE自主选择资源传输方式(如mode4)，则由上述UE接入层进行判断，如果采用基站调度传输方式(如mode3)，则由基站进行判断；针对基站判断方式，首先上述UE通过Uu口向上述基站指示V2X业务需求信息。上述判断依据以下之一：V2X业务需求信息，CBR，本地策略。其中，针对V2X业务需求信息，比如：优先级低于指定门限，和/或可靠性低于指定门限，和/或QoS只能通过增强技术实现，和/或业务(较大)只能通过增强技术传输，和/或目标地址UE能够接收增强技术，则确定可采用高版本增强技术，否则不采用；针对CBR，比如：UE测量的载波CBR低于指定门限，则确定可采用增强技术，否则不采用；针对本地策略是指：本地运营商或服务提供商确定选择增强技术，则采用增强技术传输。在实际应用中，上述依据可以单独或组合使用，相应的判断规则由基站通过RRC信令指示或者预配置在UE中。
针对基站覆盖外的UE，根据预配置的规则判断是否可采用增强技术。
上述高版本增强技术(以下简称增强技术)是指R15eV2X课题中提出的以下技术之一：CA(载波聚合，Carrier Aggregation),TxD(发送分集，Transmission Diversity)，共享资源池(mode3&mode4),副本发送，延时减少等；上述技术一般不支持后向兼容，即R14的UE不支持。
步骤S503，UE采用增强技术发送V2X业务，高版本UE接收。
上述UE或基站确定可采用增强技术，则上述UE采用增强技术发送V2X业务，针对基站调度方式，基站配置传输资源并通知UE；考虑到只有高版本UE能够支持增强技术，则高版本UE接收上述V2X业务，低版本 UE尽力接收但不能保证正确接收。
上述UE在发送的资源配置信息中指示发送版本信息，可利用现有配置信息中的保留字节指示版本信息，针对R14UE配置信息，所有的保留字节为0，针对R15UE发送配置信息中，可采用一个比特b，当该比特为1时，指示发送UE采用的R15增强技术，b＝0指示发送UE采用的R14技术；进一步的，因为只有R15UE才能识别b＝1，则b还可以用于区分发送方式，如b＝1指示R15UE采用基站调度方式，b＝0指示其他的资源配置方式(包括以下之一：R15UE自主选择方式，R14基站调度方式，R14UE自主选择方式)，当R15UE自主选择资源时，排除b＝1的资源。
步骤S504，UE采用非增强技术发送V2X业务，邻近UE接收。
上述UE或基站确定不能采用增强技术，则上述UE采用低版本的技术发送V2X业务，邻近UE(符合目标地址)接收上述业务。上述邻近UE包括高版本和低版本UE。
需要指出的是，针对不同版本UE共享资源池的场景，为了保证基站调度资源，需要预留一部分资源专用于基站调度方式，上述预留资源可通过基站广播信令指示，对于自主选择资源的UE，收到上述指示信息后，在选择资源时排除上述预留资源。针对共享资源池，上述UE自主选择资源时，根据R14的感知和资源选择/预约流程进行选择，并根据R14的重选规则进行资源重选。如果R15高版本UE采用基站调度方式，针对半持续调度，可在资源配置信息中指示半持续调度周期。
上述共享资源池包括：时域和频域资源信息。其中时域资源以子帧为单位，频域资源以资源块(RB，Resource Block)或子信道(sub channel)为单位，子信道为连续的多个RB。上述共享资源池可用于PSCCH(Physical Sidelink Control Channel，物理边路控制信道)和/或PSSCH(Physical Sidelink Shared Channel，物理边路共享信道)。
上述eNB通过系统消息SIB或专用RRC(Radio Resource Control，无 线资源控制)信令指示PC5的共享资源池配置参数。
PC5通信包括同频或异频，同频是指：Uu和PC5通信共享频率，异频是指：PC5通信采用专用频率，如5.9GHz V2X频率。
上述PC5是指UE之间的接口，也可以采用其他名称表示(如sidelink)。PC5接口可采用授权频谱的Prose技术，无线局域网WLAN/WiFi(如802.11系列)，蓝牙Bluetooth，或红外等无线传输技术。
在一个实施方式中，上述确定待发送业务对应的发送技术包括：根据以下信息至少之一确定上述待发送业务对应的发送技术：上述待发送业务的业务需求信息、当前用于发送上述待发送业务的信道忙率CBR、本地策略、预配置规则、发送/接收UE的版本。
在一实施例中，上述待发送业务的业务需求信息由UE应用层通知UE接入层，上述UE接入层或基站确定上述待发送业务对应的发送技术。
在一实施例中，在上述待发送业务为高优先级的业务时，上述发送技术为后向兼容的发送技术；在采用不同发送技术的UE共享资源池时，在上述共享资源池中保留部分资源用于基站调度。
在一个实施方式中，在确定的发送资源上发送上述待发送业务之前或者在确定的发送资源上发送上述待发送业务同时，上述方法还包括以下步骤：
步骤S11，发送版本指示信息，其中，上述版本指示信息用于指示与上述版本指示信息所指示版本相同的UE接收上述待发送业务，上述版本指示信息至少包括：第一版本指示信息、第二版本指示信息。
在一实施例中，上述发送版本指示信息包括以下步骤：
步骤S21，确定上述版本指示信息；
步骤S22，将指定信息中预设字节的取值与上述版本指示信息所指示的内容对应；
步骤S23，发送上述指定信息。
在一个实施方式中，上述确定与上述发送技术对应的发送资源包括但并不限于以下方式至少之一：由基站调度上述发送资源、上述UE自主选择上述发送资源。
其中，由基站调度上述发送资源包括：根据上述基站下发的信令确定与上述发送技术对应的发送资源；其中，上述信令用于指示在有预留资源池的情况下，上述基站在上述预留资源池中为UE选择与上述发送技术对应的发送资源，在没有预留资源池的情况下，上述基站调度共享资源池为上述UE选择的与上述发送技术对应的发送资源。
在本实施例中还提供了一种运行于上述移动终端的业务的接收方法，图6是根据本发明实施例的业务的接收方法流程图，如图6所示，该流程包括如下步骤：
步骤S602，接收指示信息，其中，该指示信息包括以下至少之一：发送用户设备UE发送的业务所使用的资源位置、接收用户设备UE的版本指示信息；该资源位置为该发送UE确定待发送业务对应的发送技术之后，确定的与该发送技术对应的资源，该发送技术至少包括：第一发送技术、第二发送技术，该第一发送技术和该第二发送技术分别对应的接收UE的版本不同；
步骤S604，根据该指示信息监听资源池，以接收该发送UE发送的业务。
在一实施例中，上述业务的接收方法的应用场景包括但并不限于：车联网V2X业务，可穿戴(Wearables)业务，机器类型通信(Machine Type Communication，MTC)，公共安全(Public Safety，PS)通信，物联网(Internet Of Thing，IOT),UE-to-Network relay等。在上述应用场景下，接收指示信息，其中，该指示信息包括以下至少之一：发送用户设备UE发送的业务所使用的资源位置、接收用户设备UE的版本指示信息；该资源位置为该发送UE确定待发送业务对应的发送技术之后，确定的与该发送技术对应的资源， 该发送技术至少包括：第一发送技术、第二发送技术，该第一发送技术和该第二发送技术分别对应的接收UE的版本不同；根据该指示信息监听资源池，以接收该发送UE发送的业务。也就是说，接收UE根据发送UE发送的指示信息监听资源池，并选择性接收业务，进而解决了相关技术中不同版本UE无法协同工作所导致的业务传输的兼容能力较差的问题，达到了提高业务传输的兼容能力的技术效果。
在一实施例中，步骤S602和步骤S604的执行顺序是可以互换的，即可以先执行步骤S604，然后再执行S602。
下面结合示例，对本发明实施例进行举例说明。
以mode3 UE的发送为例进行说明。
在本示例中提供了一种UE采用mode3方式发送业务的方法，如图7所示，包括以下步骤：
步骤S701，UE应用层向接入层指示V2X业务需求信息。
需要说明的是，上述步骤S701与上述步骤S501相同，这里不再赘述。
步骤S702，UE向基站发送请求消息。
上述UE通过RRC信令或MAC CE信令向上述基站发送请求消息。上述请求消息用于请求发送V2X业务的PC5资源。上述请求消息包括:业务标识，业务大小；进一步的还包括以下之一：业务对应的载波频率，优先级PPPP，可靠性PPPR，QoS，目的地址等。
步骤S703，基站判断UE采用的发送技术，如果是增强技术，转向步骤S704，否则，转向步骤S706。
上述基站根据以下之一确定上述发送技术：上述UE发送的请求消息，CBR，本地策略。上述发送技术包括以下之一：增强技术，非增强技术。其中增强技术是指R15中新增的技术，如：CA，TxD，共享资源池，副本传输，时延减少等一种或几种；非增强技术是指R15之前的现有技术或者R14UE采用的技术。
步骤S704，基站配置增强技术发送资源并通知UE。
上述基站确定UE采用增强技术，上述基站根据增强技术要求选择发送资源，上述基站将需要采用的增强技术和所需的资源通过RRC信令通知上述UE。
步骤S705，UE利用发送资源和增强技术发送业务。
上述UE采用增强技术和发送资源发送V2X业务，上述业务可被R15UE接收，R14UE可尽力接收但不保证成功。
步骤S706，基站配置低版本技术发送资源并通知UE。
上述基站确定不采用增强技术，则选择所需资源并通过RRC信令通知UE；
需要指出的是：针对高优先级业务，如CAM(Cooperative Awareness Message，协同感知消息)/DENM(Decentralized Environmental Notification Message，分散环境通知消息)消息等，需要所有邻近UE都接收的业务，只能采用低版本(R14)的现有技术发送，因为只有采用低版本技术发送，才能被高版本(R15)和低版本(R14)UE都正常接收。上述高优先级一般由预设的门限确定，如预设PPPP值，只有业务的PPPP需求低于预设的PPPP值时才采用低版本技术发送。
步骤S707，UE采用发送资源和低版本技术发送业务。
上述UE发送V2X业务。
在一实施例中，主要以覆盖内mode4的发送为例进行说明。
本发明实施例提供了一种覆盖内UE自主选择资源的方法，如图8所示，包括以下步骤：
步骤S801，UE应用层向接入层指示V2X业务需求。
需要说明的是，上述步骤S801与前述步骤S501类似，这里不再赘述。
步骤S802，UE确定发送的技术版本。
上述UE根据以下之一确定上述发送技术：V2X业务需求，CBR，本 地策略。上述技术版本包括以下之一：R15增强技术，或R14技术。
步骤S803，UE判断是否有所需的发送资源，如果是，转向步骤S804，否则，转向步骤S805。
上述UE根据已选择的技术版本所需资源和CBR判断是否有所需的发送资源，例如所需资源的CBR高于预设门限，则无法获取所需资源，否则可以获取。
步骤S804，UE选择资源并发送业务。
上述UE确定可获取所需资源，则在获取的资源上发送业务。
步骤S805，UE向基站发送资源请求。
上述UE确定不能获取所需资源，则向基站发送请求消息，上述请求消息包括:业务标识，业务大小；进一步的还包括以下之一：发送技术，业务对应的载波频率，优先级PPPP，可靠性PPPR，QoS，目的地址等。
步骤S806，基站配置发送资源并通知UE。
上述基站根据以下之一确定上述发送资源：上述UE发送的请求消息，CBR，本地策略；如果上述基站可配置上述UE选择技术所需的资源，则配置所需资源并通过RRC信令通知UE，否则上述基站选择其他适合V2X业务发送的技术和资源并通知UE。
步骤S807，UE发送业务。
上述UE在收到的资源上发送业务。
在一实施例中，主要以覆盖外mode4的发送为例进行说明。
本发明实施例提供了一种覆盖外UE发送业务的方法，如图9所示包括以下步骤：
步骤S901，应用层向接入层指示V2X业务需求。
步骤S902，UE确定发送技术。
上述UE根据以下之一确定发送技术：预配置规则，业务需求；上述预配置规则为事先配置好并保存在UE中，比如业务优先级高于预设门限的采 用R14技术发送，和/或CBR低于特定门限的采用R15技术发送，等等。
步骤S903，UE选择发送资源。
上述UE根据确定的发送技术选择所需的发送资源，在实际实施时，上述UE可采用R14中的资源感知和资源选择流程选择所需资源。
步骤S904，UE发送业务。
在一实施例中，主要以不同版本的资源池不共享为例进行说明。
本发明实施例提供了一种发送V2X业务的方法，如图10所示包括以下步骤：
步骤S1001，应用层向接入层指示V2X业务需求。
步骤S1002，基站或UE确定发送技术。
步骤S1003，基站或UE根据确定的发送技术选择发送资源。
考虑到不同版本的资源不共享，即R15和R14资源相互正交，则针对确定的发送技术，分别在相应的资源池中选择所需资源。
步骤S1004，UE发送业务。
上述UE在选定的资源上发送业务，因为不同版本的资源不共享，则接收UE只需要监听自己对应版本的资源池，例如R14UE只需要监听R14资源池，R15UE根据接收能力和预设规则监听相应的资源池，例如高优先级业务只能在R14资源池上发送，则R15需要监听R14资源池，如果R15UE的接收模块数小于需要监听的资源池数，则可采用时分方式监听所需资源池。
在一实施例中，主要以不同版本的资源池共享为例进行说明。
本发明实施例提供了一种发送V2X业务的方法，如图11所示主要包括以下步骤：
步骤S1101，应用层向接入层指示V2X业务需求。
步骤S1102，确定发送业务的资源配置方式，如果是基站调度，转向步骤S1103，否则转向步骤S1106。
上述资源配置方式包括以下之一：基站调度，UE自主选择。上述确定由以下之一完成：基站，本地策略。例如：基站根据业务需求和网络负载确定资源配置方式，或者本地运营商或服务提供商确定资源配置方式。
步骤S1103，基站判断是否存在预留资源池？如果是，转向步骤S1104，否则转向步骤S1105。
上述基站查看是否有为mode3预留的资源池，因为基站调度(mode3)可保证业务QoS，一般用于高优先级的业务，所以为基站调度预留部分资源，mode4UE不能选择预留的资源池。上述预留资源池大小由基站配置，并根据CBR进行调整，例如共享资源池或mode4资源池CBR高于预设门限，则基站减少预留资源池，增加共享资源池或mode4资源池。上述预留资源池的配置信息由基站通过RRC信令通知UE，如系统广播消息通知UE。
步骤S1104，基站在预留资源池选择资源并通知UE；转向步骤507。
步骤S1105，基站在共享资源池选择资源并通知UE。
没有预留资源池，则上述基站在共享资源池选择资源并通知UE。
步骤S1106，UE选择发送技术和资源。
上述UE自主选择发送技术和资源。
步骤S1107，UE发送V2X业务。
对于基站调度方式的发送UE，可在配置信息中指示半持续调度的周期数值，则自主选择UE在感知选择资源时，可以根据上述指示的周期数值排除相应的资源，从而减少自主选择资源时可能发生的冲突。
在一实施例中，主要以UE接收V2X业务为例进行举例说明。
如图12所示，包括以下步骤：
步骤S1201，UE接收指示信息。
上述指示信息包括以下之一：基站在Uu口广播信息，邻近UE通过PC5广播信息，预配置信息。上述指示信息用于指示以下之一：发送资源池，预留mode3资源池，共享资源池，门限值，发送技术版本。其中门限值包 括以下之一：优先级门限，可靠性门限，CBR门限。发送技术版本包括以下之一：R15，R14.
步骤S1202，UE选择监听的资源池。
上述UE根据指示信息和自身能力选择需要监听的资源池。
步骤S1203，UE接收所需的业务。
通过上述可选实施例，基站或UE选择V2X业务发送技术和发送资源，实现了不同版本UE的协同工作，提高了V2X业务传输的后向兼容能力。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
本发明实施例中还提供了一种业务的发送装置，该装置用于实现上述实施例，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图13是根据本发明实施例的业务的发送装置的结构框图，如图13所示，该装置包括：
确定模块132，配置为确定待发送业务对应的发送技术，其中，所述发送技术至少包括：第一发送技术、第二发送技术，所述第一发送技术和所述第二发送技术分别对应的接收用户设备UE的版本不同；
