请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个UE11以及若干个基站12。
其中，UE11可以是指向用户提供语音和/或数据连通性的设备。UE11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，UE11可以是物联网UE，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment，UE)。或者，UE11也可以是无人飞行器的设备。或者，UE11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，UE11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12 采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和UE11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，UE11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
通信领域的交互大多都是依赖需求的输入，比如，人与智慧家居的语音和/或视觉交互。按照输入的形式来划分，这种数据可以分为单模态的输入和多模态的输入。而随之智慧交互的进一步发展，更加人性化且更智能的多模态的输入会成为一种常态。这种多模态的输入是涉及多个设备的输入或者一个设备的多种输入，然后将这些输入发送给处理设备，由处理设备综合处理这些输入，最终满足不同交互场景的服务需求，例如，产生一种或多种输出。这里的多输出，也可以是通过多个设备的分别输出，也可以是通过一个设备的多种输出。
如图2所示，本公开实施例提供一种随机接入方法，其中，包括：
S110：从与多模态通信对应的随机接入前导码组中选择随机接入前导码，进行所述多模态通信的随机接入。
该随机接入方法可以应用于用户设备(User Equipment，UE)中。
多模态通信可为涉及多模态服务的通信。多模态服务可为：基于同一个场景下的不同输入提供的通信服务。
若UE基于提供或者获取多模态的触发，进行随机接入时，采用与多模态服务对应的随机接入前导码进行随机接入。
这种多模态通信的随机接入前导码，是与单模态对应的随机接入前导码不同的。
例如，多模态的通信是：UE基于用户的多种模态的输入产生的。多模态的输入可包括：文本输入、语音输入、图像输入和/或鼠标或键盘或触控面板等涉及物理设备的按压和/或触控等手动输入中多种输入的混合。
这些输入可能是用于在同一个场景，是用于某一个服务的。
例如，在会议室内，在视频会议下，有图像输入、有语音输入，若需要进行身份验证还可能有密码等文本输入、或者指纹等指纹图像的输入。这种多模态输入都是为了提供视频会议服务。
多模态输入可以是由一个支持多模态输入的设备单独完成输入采集，和输入的数据反馈，也可以是由多个设备组成的多模态通信提供系统共同完成，例如，摄像头采集图像，独立摄像头的麦克风采集语音、PC的键盘采集文本输入等。
由于多模态输入触发的多模态通信，通常相对单模态输入触发的单模态通信，具有传输的数据种类多及数据量大的特点。此时，为了区分单模态输入触发的单模态通信的随机接入，网络侧需要区分对待，以减少同一个多模态通信的部分设备的随机接入被拒绝，导致多模态通信失败或者延时大的现象。
进行多模态通信的随机接入前导码和进行单模态通信的随机接入前导码可不同，这种不同体现在以下方面的至少之一：
相同产生方式形成的不同的随机接入前导码；
不同产生方式形成的不同种类的随机接入前导码，例如，利用算法A和利用算法B生成的随机接入前导码。
在一些实施例中，多模态通信的随机接入前导码和单模态随机接入的前导码的具体差异可以体现在以下方面之一：
多模态通信的随机接入前导码和单模态通信的随机接入前导码的长度不同；例如，单模态通信的随机接入前导码对应的序列占用的比特数，不等于多模态通信的随机接入前导码对应的序列占用的比特序列。
多模态通信的随机接入前导码和单模态通信的随机接入前导码的组成不同，例如，单模态通信的随机接入前导码对应的字符串的组成包括：数字；多模态通信的随机接入前导码对应的字符串的组成包括：数字和/或字母；
多模态通信的随机接入前导码和单模态通信的随机接入前导码的格式不一样，例如，两种模态通信的随机接入前导码的序列的组成可以一样， 也可以不一样，两种模态通信的随机接入前导码的序列长度或字符串的长度可以一样或不一样，此时两种模态通信的随机接入前导码的格式不同也可以区分。随机接入前导码的长度为2M，单模态通信的随机接入前导码的组成是：前M个可以为第一预定范围内的比特序列，后M个为第二预定范围内的比特序列。而针对多模态通信的随机接入前导码的组成是：前M个可以为第二预定范围内的比特序列，后M个为第一预定范围内的比特序列。
在本公开实施例中，前述随机接入可包括：2步随机接入和/或4步随机接入。
不管怎样为单模态通信和多模态通信分别设置不同的随机接入前导码，如此在进行随机接入的随机接入请求中携带的随机接入前导码就不同，网络侧直接可以根据随机接入请求中携带的随机接入前导码区分出当前随机接入请求对应的设备接入网络之后，是将进行单模态随机接入和/或多模态随机接入请求。
在一些实施例中，为了网络侧区分不同设备发起的相同类型的随机接入，在进行随机接入时，在随机接入的随机接入请求中携带标识信息，该标识信息可方便网络侧确定出哪些随机接入请求是属于同一个多模态通信涉及的多个设备发起的。
例如，通常发起多模态通信的设备之间具有一定的关联性，通常在初始接入或者在附着过程中，会上报设备的信息，根据该信息可以告知网络侧自己所在的设备组，或者自己关联的设备。若多个可能发起多模态通信的设备，在随机接入请求中携带标识信息，则网络侧就可以很好的区分出不同设备在同一个时刻发起的多模态通信。
该标识信息，可为：包含多个设备的设备组的通信组标识；和/或，关联多个设备的关联标识。
例如，在2步随机接入中的消息A中携带所述标识信息，当然此处仅 是举例，方便网络侧进行区分同一时间发起的不同多模态通信的随机接入。
在另一个实施例中，该标识信息可为：在发起多模态通信的随机接入时，动态生成的一个口令，如此，多模态通信的多个设备不用预先建立关联或者不局限于需要位于一个组。例如，多个进行同一个多模态通信的设备之间相互协商一个口令。将该口令携带在随机接入请求中，网络侧也可以根据该口令，区分出哪些设备的随机接入是属于同一个多模态通信的设备发起的随机接入请求。
再例如，考虑到多模态通信的随机接入的特殊性，可以忽略同一个时间的相同多模态通信的并发性，可以直接通过随机接入前导码，区分单模态通信即可。
在还有一些实施例中，考虑到一个多模态通信涉及的多个设备在地理上分布的特点，可以在所述随机接入的随机接入请求中携带位置信息，该位置信息指示了设备的当前位置。后续网络侧根据发起同一个多模态通信的多个设备在地理上的集中分布，将当前位置相同或者在差异预设范围内的多个设备视为同一个多模态通信涉及的多个设备。
在本公开实施例中，针对多模态通信引起的随机接入，采用针对多模态通信的随机接入前导码发送随机接入请求，则网络侧接收到该随接入请求之后，一方面，能够区分单模态通信的随机接入请求，另一方面在确定是否应答随机接入请求时，则可以同时拒绝一个多模态通信的所有随机接入请求或者同时应答一个多模态通信的所有随机接入请求，减少一个多模态通信的部分随机接入请求被应答，随机接入成功占用了资源，但是部分随机接入请求被驳回，却不能提供对应的多模态通信的现象，从而减少一个多模态通信的部分随机接入被应答且另一部分被拒绝导致的资源浪费现象和整体上因为过多的这种部分应答和部分拒绝使得多模态通信整体上的延时大的现象。
在一些实施例中，所述S110可包括：
从与多模态通信对应的随机接入前导码组中选择随机接入前导码，进行所述多模态通信的随机接入。
多模态通信可能涉及多个设备的随机接入，因此以随机接入前导码组的方式为多模态通信配置随机接入前导码。
一种所述多模态通信，具有一个或多个所述随机接入前导码组。
一个所述随机接入前导码组包括一个或多个与所述多模态通信对应的随机接入前导码。
若所述多模态通信具有多个随机接入前导码组，则可从给同一个随机接入前导码组中选择随机接入前导码，进行随机接入。
例如，一个多模态通信涉及N个设备需要进行随机接入，为了方便基站侧进行辨认为同一个多模态通信的N个设备，则优先在该多模态通信对应的多个随机接入前导码组中的一个随机接入前导码组中选择随机接入前导码进行接入，后续，若确定出多个设备的随机接入是属于同一个多模态通信的随机接入，则会同时接受这N个设备的随机接入，或者，同时拒绝这N个设备的随机接入。此处的N可为任意正整数，例如，N为大于或等于2的正整数。
若一种多模态通信仅具有一个随机接入前导码组，则单个设备的多模态通信或者多个设备的多模态通信都可以从该随机接入前导码组选择随机接入前导码进行随机接入。
一种多模态通信的多个随机接入前导码组，包含的随机接入前导码个数可以相同或不同。例如，一种模态通信涉及的设备数可能是浮动的，此时，若该种多模态通信的多个随机接入前导码组的随机接入前导码个数不同，UE可以优先选择与当前涉及UE数量一致随机接入前导码组进行随机接入。例如，一种多模态通信涉及设备为M个，则选择包含随机接入码个 数不小于M且与M的差值最小的随机接入前导码组进行随机接入。
在一个实施例中，不同种的所述多模态通信，具有不同的所述随机前导码组。
为了区分不同种的多模态通信，为不同的多模态通信配置有不同的随机随机接入前导组，如此，网络侧可以根据随机接入请求中携带的随机前导码组的随机接入前导码，判定哪些随机接入请求是属于同一种多模态通信，从而确定是否统一拒绝同一个多模态通信的随机接入请求或者统一接受属于同一个多模态通信的随机接入请求。
通过不同种的多模态通信配置不同的随机接入前导码组，UE侧会在进行不同种多模态通信时，会采用属于不同随机接入前导组的随机接入前导码进行随机接入，如此便于网络侧进行区分。
在一些实施例中，所述多模态通信对应的随机前导码数量，与所述多模态通信的涉及设备数量正相关。
同一个多模态通信涉及的多个设备的随机接入，为了区分不同设备，这些设备需要携带不同的随机接入前导码。且不同种的多模态通信可能涉及的设备数目是不同的，为了方便涉及同一个多模态通信的所有设备都能够进行随机接入，则为该多模态通信配置的随机接入前导码的个数配置的越多。
例如，多模态通信A和多模态通信B一般情况下，多模态通信A涉及的设备数量多于多模态通信B的涉及的设备数量，则多模态通信A的随机接入前导码的数量多于多模态通信B的随机接入前导码。
多模态通信的这种随机前导码数量的配置方式，能够很好的满足不同种多模态通信的随机接入需求。
在一些实施例中，所述模态同通信对应的随机接入前导码组数，与所述多模态通信的并发数量正相关。即一种多模态通信的单位时间内发生的 次数越多，则该多模态通信的随机接入前导码组的组数越多。
在一个实施例中，所述模态同通信对应的随机接入前导码组数，与所述多模态通信的并发数量正相关，一个所述多模态通信对应的随机前导码数量，与所述多模态通信的涉及设备数量正相关，如此，可以满足不同通信需求的多模态通信的随机接入请求的需求。
在一些实施例中，如图3所示，所述方法还包括：
S100：接收指示与所述多模态通信对应的所述随机接入前导码的对应关系信息。
网络侧的接入网元(例如，各种类型基站或收发点)等，可以下发所述多模态通信对应的随机接入前导码的对应关系信息。
该对应关系信息，指示不同种多模态通信与随机接入前导码的对应关系。如此，UE接收到该对应关系信息之后，就可以根据对应关系信息指示的对应关系，在进行多模态通信时选择对应的随机接入前导码进行随机接入。
该对应关系信息可以是单播发送、组播发送或者广播发送。
例如，基站可以在小区内广播发送所述随机接入消息，如此，在小区内的所有的UE都能够接收到所述对应关系信息，相对单播发送可以减少基站发送对应关系信息的次数和信令开销。
再例如，能够进行多模态通信的UE需要在网络侧进行多模态通信的注册或者订阅，则此时网络侧预先知道哪些UE会进行多模态通信，因此，可以在小区内这些设备内组播所述对应关系信息，如此，仅进行单模态通信的UE就不会接收到这些对应关系信息，从而减少了仅进行单模态通信的UE所需接收的信令。
当然在另一些实施例中，该对应关系信息也可以采用RRC信令等单播信令单播给对应的UE。
当然这些对应关系信息也可以预先写入到UE内，例如，对应关系信息预先写入到通信协议中，如此，UE和基站之间就不用就多模态通信的随机接入前导码有专门的信令指示了。
在一些实施例中，所述对应关系信息指示：
所述多模态通信的通信标识ID与所述多模态通信对应的随机接入前导码所在随机接入前导码组的组ID之间的对应关系；
或者，
所述多模态通信的通信ID与所述多模态通信对应的随机接入前导码的码ID之间的对应关系。
不同种的多模态通信具有不同的通信ID，如此，可以利用该ID构建与随机接入前导码之间的对应关系。
该通信ID可以由网络侧基站配置，或者核心网的核心网设备配置，还可以是通信网络的运维管理设备(Operation Administration Maintenance，OAM)配置。
在本公开实施例中，所述对应关系可以直接是通信ID和对应的一个个随机接入前导码。在本公开实施例中，为了方便进行对应关系信息的配置，可以为每一个随机接入前导码配置ID或者每一个随机接入前导码组配置组ID。此时，在对应关系信息中就可以使用多模态通信的通信ID和随机接入前导码的ID或者随机接入前导码组的组ID。
在本公开实施例中，所述对应关系信息包括：多模态通信的通信ID和对应的随机接入前导码的ID；或者，多模态通信的通信ID和对应的随机接入前导码组的组ID。
在一些实施例中，所述方法还包括：
接收为所述多模态通信分配的通信ID。
网络侧通过通信ID的广播，一方面可以告知UE需要小区支持哪些多 模态通信，另一方面可以方便UE接收到所述对应关系信息之后，确定各种多模态通信对应的随机接入前导码。
在一些实施例中，所述从与多模态通信对应的随机接入前导码组中选择随机接入前导码，进行所述多模态通信的随机接入，包括：
在一种所述多模态通信具有多个随机接入前导码组时，选择同一所述随机接入前导码组进行随机接入。
若一种多模态通信配置有多个随机接入前导码组的时候，优先在一个随机接入前导码组内选择随机接入前导码进行随机接入时，此时即便在小区内存在同种多模态通信的并发，也可以根据随机接入请求中携带的随机接入前导码所归属的随机接入前导码组，确定出哪些随机接入请求是同一个多模态通信的设备发起的。
在一些实施例中，所述从与多模态通信对应的随机接入前导码组中选择随机接入前导码，进行所述多模态通信的随机接入，包括：
在一个所述随机接入前导码组的数量少于所述多模态通信涉及的设备数量时，选择至少两个所述随机接入前导码组内的随机接入前导码进行随机接入。
若一种多模态通信具有多个随机接入前导码组，若某一个随机接入前导码组的随机接入前导码不够时，可以跨组进行随机接入前导码选择。例如，有两个或3个随机接入前导码组，可以在两个或三个随机接入前导码组进行随机接入。
在一些实施例中，所述方法，包括：
在所述多模态通信的随机接入前导码均已被参与所述多模态通信的设备所使用时，采用单模态通信对应的随机接入前导码进行随机接入。
若一种多模态通信具有随机接入前导组，若当前该组内的随机接入前导码均被其他设备使用，则当前UE从单模态通信对应的随机接入前导码进 行随机接入。若一种多模态通信具有随机接入前导组，若当前随机接入前导码组内的随机接入前导码均被其他设备使用，则从该多模态通信的其他随机接入前导码组中选择随机接入前导码进行随机接入，若其他组的随机接入前导码也被用完，则当前UE从单模态通信对应的随机接入前导码进行随机接入。
若一种多模态通信的随机接入前导码耗尽的情况下，可以暂时借用单模态通信的随机接入前导码进行随机接入，减少了多模态通信的随机接入请求的延时，进而减少了多模态通信的延时。
在一些实施例中，所述方法，还包括：
在单模态通信的随机接入前导码均已使用，暂缓发送随机接入请求，即不会占用多模态通信的随机接入前导码进行随机接入，减少单模态通信的随机接入请求被网络侧误认为是多模态通信的随机接入请求接受或拒绝。
如图4所示，本公开实施例中一种随机接入方法，其中，所述方法包括：
S210：接收随机接入请求；
S220：根据所述随机接入请求携带的随机接入前导码时，确定是否为基于多模态通信的发起的随机接入。
本公开实施例提供的随机接入方法，可应用于各种基站或收发嗲(TRP)等接入设备中。
该接入设备会接收随机接入请求，会根据随机接入请求中携带的随机接入前导码，确定当前发起随机接入请求的愿意是需要进行多模态通信或者单模态通信。
在一个实施例中，所述S220可包括：

在另一个实施例中，所述S220可包括：
若随机接入请求携带的随机接入前导码为单模态通信对应的随机接入前导码，则确定所述随机接入请求是基于单模态通信发起的随机接入，而不是基于多模态通信发起的随机接入。
在一些实施例中，所述方法还包括：

在一些实施例中，所述方法还包括：

该通信ID的配置可以由前述实施例中提到的OAM设备或者接入设备 配置的。此处的下发通信ID同样可以采用广播、组播或者单播方式中的任一一种方式下发。
在一些实施例中，一种所述多模态通信，具有一个或多个所述随机接入前导码组；一个所述随机接入前导码组包括一个或多个与所述多模态通信对应的随机接入前导码。

在一些实施例中，如图5所示，所述方法还包括：
S230：拒绝同一个所述多模态通信的多个随机接入请求；或者接受同一个所述多模态通信的多个随机接入请求。
例如，接入设备按照一定的算法，拒绝或者接受对应设备的随机接入请求，但是在本公开实施例中，接入设备在决绝或者接受随机接入请求时，针对多模态通信的多个随机接入请求，会一起接受或者一起拒绝。如此，这种随机接入请求的处理方式，可以减少多个设备发起的同一个多模态通信的随机接入请求部分被接受导致的多模态通信不能同步开始，导致的通信失败或者通信效果差或者延时大的现象。
