以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)接入网设备，是通信系统中将终端接入到无线网络的设备。所述接入网设备为无线接入网中的节点，又可以称为基站，还可以称为无线接入网(radio access network，RAN)节点(或设备)。目前，一些接入网设备的举例为：gNB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。另外，在一种网络结构中，所述接入网设备可以包括集中单元(centralized unit，CU)节点和分布单元(distributed unit，DU)节点。这种结构将长期演进(long term evolution，LTE)系统中eNB的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
2)本申请涉及的终端为能够承载多媒体业务的终端。终端可以是终端设备，也可以是终端设备中的一个或多个芯片，或者是终端设备中的一个或多个处理器，或者是终端设备中的一个或多个模块，本申请实施例对此不作具体限定。终端设备也可以称为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
3)、本申请涉及到的业务可以为多媒体广播多播业务(multimedia broadcast multicast service，MBMS)。MBMS数据一般通过广播形式提供。比如在LTE中，每个小区可以有几个子帧用来发送MBMS数据，所有UE可以通过接收这几个子帧来接收MBMS数据，UE可以在空闲态或者连接态接收MBMS子帧，eNB可不必知道有哪些UE在接收。当然对于连接态接收MBMS业务的终端，eNB可以通过发起counting(统计)过程获知哪些连接态UE在接收或者感兴趣的UE在接收MBMS业务。
LTE中MBMS采用多播/组播单频网络(multicast broadcast single frequency network，MBSFN)技术或者单小区点到多点(single cell point to multipoint，SC-PTM)技术。
MBMSFN要求同时传输来自多个小区的完全相同的波形。这样一来，UE能将多个MBSFN小区视为一个大的小区。此外，UE不仅不会受到相邻小区传输的小区间干扰，而且将受益于来自多个MBSFN小区的信号的叠加。传输来完全相同的波形的多个小区的组成一个MBSFN area，在一个area内部可以配置多个PMCH(物理多播信道)信道，其中每个信道上又可以承载MBMS业务。
SC-PTM是一种多播传输技术。LTE最先引入的多播技术是eMBMS，eMBMS技术中， 一个区域内所有小区要求同时发送相同内容，如果UE只分布在部分小区，则eMBMS技术传输效率相对较低，为此，3GPP标准又提出了SC-PTM技术，在SC-PTM技术中，小区通过G-RNTI来同时向多个UE调度业务数据，每个G-RNTI可以关联一个MBMS业务。这样，在一个区域内，只有包含用户的小区需要发送数据，不包含用户的小区不需要发送数据从而节省了空口资源。
现有技术同一多播业务的不同版本需要不同的资源传输，比如CCTV1标清需要1M带宽，高清需要2M带宽，则总共消耗3M带宽，而实际上高清视频是由标清视屏增加了像素点实现的，相当于这2M高清中传输的信息其实包含了1M标清中传输的数据。而现有的高清和标清的重复传输，导致传输效率相对较低。
基于此，本申请实施例提供一种多媒体业务的传输方法及装置，用以解决现有技术中存在的传输效率低的问题。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
参见图2所示，为本申请实施例提供的一种多媒体业务的传输方法流程示意图。
S201，终端接收第一版本的业务信息，以及接收第二版本的业务信息，其中，第一版本的业务信息包括第一业务的第一版本的数据，第二版本的业务信息包括所述第一业务的第二版本相对于所述第一业务的第一版本的增量数据。
后续描述中将第二版本相对于所述第一业务的第一版本的增量数据，简称为第二版本的增量数据。
本申请实施例执行多媒体业务的传输方法的终端可以是终端设备，也可以是终端设备中的一个或多个芯片，或者是终端设备中的一个或多个处理器，或者是终端设备中的一个或多个模块，本申请实施例对此不作具体限定。
示例性的，所述第二版本的增量数据为所述第一业务的第二版本所需的数据中与所述第一版本的数据不同的数据，第一业务的所述第二版本的传输质量高于第一业务的所述第一版本。比如，第一业务为视频业务，视频业务的第二版本可以是高清版本，而第一版本可以是标清版本。
可选地，终端接收第一版本的业务信息，以及接收第二版本的业务信息之前，所述终端可以先获取第一版本的业务和第二版本的业务标识。
所述终端可以先获取第一版本的业务标识和第二版本的业务标识，可以从接入网设备获取，或者从服务器(server)获取，或者从核心网设备获取。本申请对此不作具体限定。示例性的，终端可以通过用户服务描述(user server description，USD)信息获取。USD信息为server中的信息。
本申请实施例中的第一业务可以是多播业务，多播业务可以通过临时移动组标识(temporary mobile group identity，TMGI)来标识，TMGI可以用来唯一确定一个多播业务。UE获知具体某个业务的TMGI后进行该业务的接收。比如CCTV1通过MBMS方式发送，如果UE接收CCTV1之前，则需要先确定CCTV1的TMGI，然后在小区确定该TMGI的发送资源从而接收该业务。
示例性的，一个业务的不同的版本对应的业务标识可以通过TMGI或者TMGI加其他标识来表示，比如TMGI+session ID。例如，TMG1表示业务1的标清版本，TMG2表示业务1的高清增量版本。再比如，TMGI1的session1表示业务1的标清版本，TMG1的session2表示业务1的高清增量版本。
S202，所述终端将所述第一版本的数据和所述第二版本的增量数据进行合并，得到所述第一业务的第二版本的数据。
通过本申请实施例提供的方案，针对增强数据并不是传输所有的数据，而是传输在基本数据的基础上增加的像素点对应的数据，从而避免了不同版本之间数据的重复传输，进而能够提高传输效率。
在一种可行的实施例中，第一版本的业务信息和第二版本的业务信息可以由不同的接入网设备发送。示例性的，第一版本的业务信息可以由第一接入网设备向终端发送，第二版本的业务信息可以由第二接入网设备向终端发送。则所述终端在接收第一版本的业务信息时，可以从第一接入网设备接收第一版本的业务信息；所述终端在接收第二版本的业务信息时，可以从第二接入网设备接收所述第二版本的业务信息；其中，所述第一接入网设备和所述第二接入网设备为不同的设备。第一接入网设备可以是大覆盖范围的基站，第二接入网设备可以是小覆盖范围的基站。第一接入网设备的覆盖范围可以包括第二接入网设备的覆盖范围，换句话说，第二接入网设备位于第一接入网设备的覆盖范围内。示例性的，第一接入网设备可以是大塔，而第二接入网设备可以是小站。
在一种可行的实施例中，所述终端将所述第一版本的数据和所述第二版本的增量数据进行合并时，可以通过如下方式实现：
第一种可能的实现方式：

所述终端根据所述合并序列号将所述第一数据包和所述第二数据包进行合并。
合并序列号用于表示第二版本的增量数据和第一版本的数据中哪些数据包之间存在关联关系。本申请实施例中以两个版本的同一帧数据配置相同的合并序列号为例进行说明。比如第一版本业务时CCTV1的标清数据，第二版本业务时CCTV1的高层增量版本，对于同一数据帧的标清数据和高清数据，两个版本可以设置相同的合并序列号。当然还可以预先建立合并序列号之间的对应关系，从而配置在服务器以及终端中。从而终端根据数据包对应的合并序列号确定哪些数据包之间需要进行合并。另外，在本申请实施例中一个数据帧中包括的数据可以构成一个数据包。
该合并序列号可以由服务器添加并连同版本数据发送给接入网设备，也可以由接入网设备来添加。示例性的，由接入网设备来添加，服务器可以在将数据包传输给接入网设备时携带该数据包的合并序列号辅助信息，以便接入网设备根据合并序列号的辅助信息生成合并序列号。所述合并序列号辅助信息可以是该数据包的生成时间信息，或者改数据包的顺序号信息。基站添加的合并序列号可以放置在PDCP的SN或者RLC的SN位置。
在第一种可能的示例中，合并序列号由服务器添加，第一版本的数据由第一接入网设备发送给终端。则第一接入网设备接收服务器发送的第一版本的第一业务信息，所述第一版本的第一业务信息中包括所述第一版本的数据，所述第一版本的数据中包括第二数据包，所述第一版本的第一业务信息中还包括所述第二数据包的合并序列号；所述第一接入网设备向终端发送所述第一版本的第一业务信息。
第二版本的增量数据由第二接入网设备发送给终端。则第二接入网设备接收服务器发 送的第二版本的第一业务信息，所述第二版本的第一业务信息中包括所述第二版本的增量数据，所述第二版本的增量数据中包括第一数据包，所述第二版本的第一业务信息中还包括所述第一数据包的合并序列号；所述第二接入网设备向终端发送所述第二版本的第一业务信息。从而所述终端根据所述合并序列号将所述第一数据包和所述第二数据包进行合并。
在第二种可能的示例中，合并序列号由接入网设备添加，第一版本的数据由第一接入网设备发送给终端。所述第一接入网设备接收所述服务器发送的第一版本的第一业务信息，所述第一版本的第一业务信息中包括所述第一版本的数据，所述第一版本的数据中包括第二数据包，所述第一版本的第一业务信息中还包括所述第二数据包的合并序列号辅助信息；所述接入网设备根据所述合并序列号辅助信息生成所述第二数据包的合并序列号；所述接入网设备向终端发送第一版本的第二业务信息，所述第一版本的第一业务信息中包括所述第一版本的数据，所述第一版本的第二业务信息中还包括所述第二数据包的合并序列号。
第二版本的数据由第二接入网设备发送给终端。所述第二接入网设备接收所述服务器发送的第二版本的第一业务信息，所述第二版本的第一业务信息中包括所述第二版本的增量数据，所述第二版本的增量数据中包括第一数据包，所述第二版本的第一业务信息中还包括所述第一数据包的合并序列号辅助信息；所述第二接入网设备根据所述合并序列号辅助信息生成所述第一数据包的合并序列号；所述第二接入网设备向终端发送第二版本的第二业务信息，所述第二版本的第一业务信息中包括所述第二版本的增量数据，所述第二版本的第二业务信息中还包括所述第一数据包的合并序列号。从而所述终端根据所述合并序列号将所述第一数据包和所述第二数据包进行合并。
第二种可能的实现方式：
所述第一版本的数据包括第一数据包，所述第二版本的增量数据包括第二数据包，将所述第一版本的数据以及所述第二版本的增量数据进行合并，包括：
所述终端根据所述第一数据包的接收时间与所述第二数据包的接收时间，将所述第一数据包和所述第二数据包进行合并；
其中，所述第一数据包的接收时间与所述第二数据包的接收时间相同，或者，所述第二数据包的接收时间与所述第二数据包的接收时间之间的差值小于门限值。
需要说明的是，本申请实施例中的第一数据包泛指第一版本的数据中的任一数据包，第二数据包泛指第二版本的增量数据中的任一数据包。
