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：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110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，用户设备110可以是物联网用户设备，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机，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、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110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用户设备。或者，用户设备110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120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)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120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120的具体实现方式不加以限定。
基站120和用户设备110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，用户设备110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，车对基础设施)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
这里，上述用户设备可认为是下面实施例的终端设备。
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130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130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130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130的实现形态，本公开实施例不做限定。
为了方便对本公开任一实施例的理解，首先，对多模态业务的应用场景进行说明。
请参见图2，在一个实施例中，多模态业务的系统包括基站11、集中处理设备12、终端13、终端14和终端15。在一个实施例中，终端13和终端14为多模态业务的输入设备，集中处理设备12为多模态业务的处理设备，终端15为多模态业务的输出设备。这里，终端13和/或终端14都可以在多个模态下进行数据的输入，例如，终端13可以在2个模态下进行数据。这里，集中处理设备12可以对终端13和终端14输入的数据进行处理，然后将处理后的数据发送给终端15。这里，发送给终端15的数据可以是多个模态下的数据输出。这里，集中处理设备12可以是采用机器学习算法进行输入数据的处理，例如，利用神经网络算法进行输入数据的处理。
这里，在终端13和/或终端14在向集中处理设备12发送数据之前或者集中处理设备12向终端15发送数据之前，终端13、终端14、终端15和集中处理设备12都需要与基站11建立无线资源控制(RRC)连接。建立无线资源控制(RRC)连接需要进行随机接入。大部分多模态业务对无线 通信时延的要求较高，如果能够降低多模态通信终端随机接入时产生的时延，那么会提升用户体验。
如图3所示，本实施例中提供一种随机接入的方法，其中，应用于终端，该方法包括：
步骤31，发送与多模态业务的业务类型相关联的随机接入请求。
在一个实施例中，随机接入请求为随机接入的第一消息(Msg1)或者随机接入前导码。
该终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备等。
在一个实施例中，该终端可以是多模态业务对应的多个终端中的任一一个终端。例如，该终端可以是图2中的用于多模态业务的数据输入的终端12。该终端还可以是图2中的用于多模态业务的数据输出的终端15。
在一个实施例中，可以是基站接收随机接入请求。该基站为终端接入网络的接口设备。基站可以为各种类型的基站，例如，第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
在一个实施例中，多模态业务可以是在多个模态下进行数据输入和/或在多个模态下进行数据输出的业务。这里，可以是通过多个终端分别进行各个模态下的数据输入，或者通过一个终端进行各个模态下的数据输入。这里，可以是通过多个终端分别进行各个模态下的数据输出，或者通过一个终端进行各个模态下的数据输出。这里，一种模态下的数据可以是具有预定特征的数据。例如，具有姿态特征的数据可以是一种模态下的数据，具有人脸特征的数据可以是另一种模态下的数据。
在一个实施例中，多模态业务的业务类型可以是根据多模态业务的通 信时延确定的。例如，当多模态业务的通信时延小于第一阈值时，该多模态业务的业务类型为第一业务类型；当多模态业务的通信时延大于第一阈值且小于第二阈值时，该多模态业务的业务类型为第二业务类型；当多模态业务的通信时延大于第二阈值时，该多模态业务的业务类型为第三业务类型。这里，第一阈值小于第二阈值。
在一个实施例中，多模态业务的业务类型可以是根据多模态业务的业务优先级确定的。例如，当多模态业务的业务优先级为高优先级时，该多模态业务的业务类型为第一业务类型；当多模态业务的业务优先级为低优先级时，该多模态业务的业务类型为第二业务类型。
在一个实施例中，响应于接收到基站发送的寻呼信令，发送与多模态业务的业务类型相关联的随机接入请求。这里，多模态业务的终端通过发起随机接入请求的方式触发随机接入过程以建立无线资源控制(RRC)连接以实现多模态业务的无线通信。这里，终端可以是处于无线资源控制(RRC)空闲态。这里，随机接入请求可以是无线资源控制(RRC)连接建立请求，或者，无线资源控制(RRC)连接恢复请求。
在一个实施例中，寻呼信令携带有终端针对所述多模态业务接入的随机接入信息。终端利用该随机接入信息发送与多模态业务的业务类型相关联的随机接入请求。这里，随机接入信息可以包括用于随机接入的时频域资源和/或前导码序列。这里，利用寻呼信令携带的随机接入信息发送随机接入请求可以减少终端在传输数据时因为不同终端在使用资源时的资源碰撞带来的干扰。
在一个实施例中，多模态业务可以是多方认证的支付业务。例如，A终端需要完成支付业务需要获得B终端的人脸数据和C终端的语音数据进行认证。在A终端进行该支付业务时，A终端可以通过核心网向基站发送认证请求。基站在接收到该认证请求后，向该支付业务的处于空闲态的B终端和处于空闲态的C终端发送一个寻呼信令，B终端和C终端在接收到 寻呼信令后发送与多模态业务的业务类型相关联的随机接入请求，并与基站建立无线资源控制(RRC)连接。然后，B终端向基站发送人脸数据，C终端向基站发送语音数据。
在一个实施例中，可以是终端有待传输的多模态业务的输出数据需要发送给基站时，发送与多模态业务的业务类型相关联的随机接入请求。这样，终端在有待传输的多模态业务的输出数据时，能够及时发送给基站，并通过基站将该多模态业务的输出数据发送给集中处理设备进行处理。
在一个实施例中，可以是多模态事件发生时，发送与多模态业务的业务类型相关联的随机接入请求。
在一个实施例中，多模态事件发生可以是当前的时间为设置的时刻。例如，安保业务为多模态业务，在安保系统中，终端在设置的时间点到达时需要向安保业务的多个处理设备传输声音数据和图像数据，会发送与多模态业务的业务类型相关联的随机接入请求。
在一个实施例中，不同业务类型的多模态业务可以通过身份标识(ID)进行区分。例如，第一业务类型的多模态业务的身份标识(ID)为“001”；第二业务类型的多模态业务的身分识别标识(ID)为“010”。
在一个实施例中，不同业务类型的多模态业务的身份标识(ID)不同，随机接入请求与多模态业务的身份标识(ID)相关联。例如，与智能驾驶相关的多模态业务的身份标识为“001”，与智能驾驶相关的多模态业务的随机接入请求携带有“001”的身份标识(ID)信息；与远程医疗相关的多模态业务的身份标识为“010”，与远程医疗相关的多模态业务的随机接入请求携带有“010”的身份标识(ID)信息。
在一个实施例中，随机接入请求与多模态业务的身份标识(ID)相关联，包括：
随机接入请求是被身份标识(ID)加扰的；
或者，
随机接入请求携带身份标识(ID)。
在一个实施例中，终端利用身份标识(ID)对随机接入请求进行加扰，基站在接收到该随机接入请求后，就可以利用不同的身份标识对随机接入请求进行解扰。当解扰成功时，确定解扰成功时所使用的身份标识(ID)为与随机接入请求关联的身份标识。这里，身份标识(ID)可以是一个二进制数序列。
例如，身份标识为第一身份标识的多模态业务A需要发起随机接入，终端利用第一身份标识(ID)对随机接入请求进行加扰。基站在接收到利用该第一身份标识(ID)加扰的随机接入请求后，会分别利用第一身份标识(ID)、第二身份标识(ID)和第三身份标识(ID)对随机接入请求进行解扰，由于只有使用第一身份标识(ID)才能够解扰成功，则基站确定第一身份标识(ID)为与该随机接入请求关联的身份标识(ID)，该第一身份标识(ID)对应的多模态业务为终端请求进行随机接入的多模态业务A。
在一个实施例中，随机接入请求携带多模态业务的身份标识(ID)，基站在接收到该随机接入请求后，就可以对该随机接入请求进行解码。基站解码出该随机接入请求携带的身份标识(ID)，从而确定第一身份标识(ID)为与该随机接入请求关联的身份标识(ID)，该第一身份标识(ID)对应的多模态业务为终端请求进行随机接入的多模态业务。这里，身份标识(ID)可以是一个二进制数序列。
例如，身份标识为第一身份标识(ID)的多模态业务B需要发起随机接入，发送给基站的随机接入请求携带有第一身份标识(ID)，基站在接收到该随机接入请求后，就可以对该随机接入请求进行解码，如果解码出该随机接入请求携带的第一身份标识(ID)，就可以确定第一身份标识(ID)为与该随机接入请求关联的身份标识(ID)，该第一身份标识(ID)对应的多模态业务为终端请求随机接入的多模态业务B。
这里，由于随机接入请求与多模态业务的身份标识(ID)相关联，基站在接收到随机接入请求后，就可以基于该身份标识(ID)确定该多模态业务的业务类型。基站可以根据该多模态业务的业务类型确定是否为基站优先允许接入的多模态业务，从而确定针对该随机接入请求的随机响应操作。例如，可以发送针对该随机接入请求的随机接入响应(RAR)，使得终端基于该随机接入响应(RAR)快速接入网络。
在一个实施例中，该身份标识(ID)为：
为多模态业务临时分配的；
或者，
身份标识(ID)为：为多模态业务预先分配的。
在一个实施例中，可以是在有多模态业务需求时临时给多模态业务临时分配的。例如，身份标识(ID)可以是当集中处理设备需要多模态业务的多个处于无线资源控制(RRC)空闲态的终端输入数据时为多模态业务临时分配的。
在另一个实施例中，为多模态业务临时分配可以是在多模态事件发生时给多模态业务临时分配的。例如，身份标识(ID)可以是当前的时间为设置多模态事件发生的时刻为多模态业务临时分配的。

该终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备 等。
在一个实施例中，该终端可以是多模态业务对应的多个终端中的任一一个终端。例如，该终端可以是图2中的用于多模态业务的数据输入的终端12。该终端还可以是图2中的用于多模态业务的数据输出的终端15。
该基站为终端接入网络的接口设备。基站可以为各种类型的基站，例如，第三代移动通信(3G)网络的基站、第四代移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
在一个实施例中，多模态业务可以是在多个模态下进行数据输入和/或在多个模态下进行数据输出的业务。这里，可以是通过多个终端分别进行各个模态下的数据输入，或者通过一个终端进行各个模态下的数据输入。这里，可以是通过多个终端分别进行各个模态下的数据输出，或者通过一个终端进行各个模态下的数据输出。这里，一种模态下的数据可以是具有预定特征的数据。例如，具有姿态特征的数据可以是一种模态下的数据，具有人脸特征的数据可以是另一种模态下的数据。
在一个实施例中，多模态业务的业务类型可以是根据多模态业务的通信时延确定的。例如，当多模态业务的通信时延小于第一阈值时，该多模态业务的业务类型为第一业务类型；当多模态业务的通信时延大于第一阈值且小于第二阈值时，该多模态业务的业务类型为第二业务类型；当多模态业务的通信时延大于第二阈值时，该多模态业务的业务类型为第三业务类型。这里，第一阈值小于第二阈值。
在一个实施例中，多模态业务的业务类型可以是根据多模态业务的业务优先级确定的。例如，当多模态业务的业务优先级为高优先级时，该多模态业务的业务类型为第一业务类型；当多模态业务的业务优先级为低优先级时，该多模态业务的业务类型为第二业务类型。
在一个实施例中，响应于接收到基站发送的寻呼信令，终端发送与多模态业务的业务类型相关联的随机接入请求。这里，多模态业务的终端通 过发起随机接入请求的方式触发随机接入过程以建立无线资源控制(RRC)连接以实现多模态业务的无线通信。这里，终端可以是处于无线资源控制(RRC)空闲态。这里，随机接入请求可以是无线资源控制(RRC)连接建立请求，或者，无线资源控制(RRC)连接恢复请求。
在一个实施例中，寻呼信令携带有终端针对所述多模态业务接入的随机接入信息。终端利用该随机接入信息发送与多模态业务的业务类型相关联的随机接入请求。这里，随机接入信息可以包括用于随机接入的时频域资源和/或前导码序列。这里，利用寻呼信令携带的随机接入信息发送随机接入请求可以减少终端在传输数据时因为不同终端在使用资源时的资源碰撞带来的干扰。
在一个实施例中，多模态业务可以是多方认证的支付业务。例如，A终端需要完成支付业务需要获得B终端的人脸数据和C终端的语音数据进行认证。在A终端进行该支付业务时，A终端可以通过核心网向基站发送认证请求。基站在接收到该认证请求后，向该支付业务的处于空闲态的B终端和处于空闲态的C终端发送一个寻呼信令，B终端和C终端在接收到寻呼信令后发送与多模态业务的业务类型相关联的随机接入请求，并与基站建立无线资源控制(RRC)连接。然后，B终端向基站发送人脸数据，C终端向基站发送语音数据。
在一个实施例中，可以是终端有待传输的多模态业务的输出数据需要发送给基站时，发送与多模态业务的业务类型相关联的随机接入请求。这样，终端在有待传输的多模态业务的输出数据时，能够及时发送给基站，并通过基站将该多模态业务的输出数据发送给集中处理设备进行处理。
在一个实施例中，可以是多模态事件发生时，发送与多模态业务的业务类型相关联的随机接入请求。
在一个实施例中，多模态事件发生可以是当前的时间为设置的时刻。例如，安保业务为多模态业务，在安保系统中，终端在设置的时间点到达 时需要向安保业务的多个处理设备传输声音数据和图像数据，会发送与多模态业务的业务类型相关联的随机接入请求。
在一个实施例中，不同业务类型的多模态业务可以通过身份标识(ID)进行区分。例如，第一业务类型的多模态业务的身份标识(ID)为“001”；第二业务类型的多模态业务的身分识别标识(ID)为“010”。
在一个实施例中，不同业务类型的多模态业务的身份标识(ID)不同，随机接入请求与多模态业务的身份标识(ID)相关联。例如，与智能驾驶相关的多模态业务的身份标识为“001”，与智能驾驶相关的多模态业务的随机接入请求携带有“001”的身份标识(ID)信息；与远程医疗相关的多模态业务的身份标识为“010”，与远程医疗相关的多模态业务的随机接入请求携带有“010”的身份标识(ID)信息。
在一个实施例中，随机接入请求与多模态业务的身份标识(ID)相关联，包括：
随机接入请求是被身份标识(ID)加扰的；
或者，
随机接入请求携带身份标识(ID)。
在一个实施例中，终端利用身份标识(ID)对随机接入请求进行加扰，基站在接收到该随机接入请求后，就可以利用不同的身份标识对随机接入请求进行解扰。当解扰成功时，确定解扰成功时所使用的身份标识(ID)为与随机接入请求关联的身份标识。这里，身份标识(ID)可以是一个二进制数序列。
例如，身份标识为第一身份标识的多模态业务A需要发起随机接入，终端利用第一身份标识(ID)对随机接入请求进行加扰。基站在接收到利用该第一身份标识(ID)加扰的随机接入请求后，会分别利用第一身份标识(ID)、第二身份标识(ID)和第三身份标识(ID)对随机接入请求进行解扰，由于只有使用第一身份标识(ID)才能够解扰成功，则基站确定 第一身份标识(ID)为与该随机接入请求关联的身份标识(ID)，该第一身份标识(ID)对应的多模态业务为终端请求进行随机接入的多模态业务A。
在一个实施例中，随机接入请求携带多模态业务的身份标识(ID)，基站在接收到该随机接入请求后，就可以对该随机接入请求进行解码。基站解码出该随机接入请求携带的身份标识(ID)，从而确定第一身份标识(ID)为与该随机接入请求关联的身份标识(ID)，该第一身份标识(ID)对应的多模态业务为终端请求进行随机接入的多模态业务。这里，身份标识(ID)可以是一个二进制数序列。
例如，身份标识为第一身份标识(ID)的多模态业务B需要发起随机接入，发送给基站的随机接入请求携带有第一身份标识(ID)，基站在接收到该随机接入请求后，就可以对该随机接入请求进行解码，如果解码出该随机接入请求携带的第一身份标识(ID)，就可以确定第一身份标识(ID)为与该随机接入请求关联的身份标识(ID)，该第一身份标识(ID)对应的多模态业务为终端请求随机接入的多模态业务B。
这里，由于随机接入请求与多模态业务的身份标识(ID)相关联，基站在接收到随机接入请求后，就可以基于该身份标识(ID)确定该多模态业务的业务类型。基站可以根据该多模态业务的业务类型确定是否为基站优先允许接入的多模态业务，从而确定针对该随机接入请求的随机响应操作。例如，可以发送针对该随机接入请求的随机接入响应(RAR)，使得终端基于该随机接入响应(RAR)快速接入网络。
在一个实施例中，该身份标识(ID)为：
为多模态业务临时分配的；
或者，
身份标识(ID)为：为多模态业务预先分配的。
在一个实施例中，可以是在有多模态业务需求时临时给多模态业务临 时分配的。例如，身份标识(ID)可以是当集中处理设备需要多模态业务的多个处于无线资源控制(RRC)空闲态的终端输入数据时为多模态业务临时分配的。
在另一个实施例中，为多模态业务临时分配可以是在多模态事件发生时给多模态业务临时分配的。例如，身份标识(ID)可以是当前的时间为设置多模态事件发生的时刻为多模态业务临时分配的。
这里，当多模态业务发起时，可以临时分配身份标识(ID)，在多模态业务结束时，可以释放临时分配的身份标识(ID)。这样，可以减少身份标识(ID)的资源一直被占用的情况，使得身份标识(ID)的分配更加灵活，身份识别标识(ID)的使用更加高效。

在一个实施例中，身份标识(ID)是：核心网分配的，或者接入网分配的。
在一个实施例中，身份标识(ID)可以是集中处理设备通过核心网向基站发送寻呼多模态业务的终端时核心网分配的。
在一个实施例中，身份标识(ID)是接入网分配的可以是基站在发送寻呼信令前给多模态业务分配的。
在一个实施例中，随机接入请求与多模态业务的身份标识(ID)相关联，包括：
随机接入请求的随机接入前导码，与多模态业务具有对应关系。
在一个实施例中，预先给不同的多模态业务分配不同的随机接入前导 码。例如，给第一业务类型的多模态业务分配的随机接入前导码为前导码1、前导码2和前导码3；给第二业务类型的多模态业务分配的随机接入前导码为前导码4、前导码5和前导码6。当在针对第一业务类型的多模态业务发起随机接入时，将从前导码1、前导码2和前导码3中选择一个前导码作为随机接入请求的前导码。当在针对第二业务类型的多模态业务发起随机接入时，将从前导码4、前导码5和前导码6中选择一个前导码作为随机接入请求的前导码。这里，随机接入请求的随机接入前导码与多模态业务的映射关系可以是通过基站广播给终端的。如此，基站在接收到随机接入请求时，就可以根据随机接入前导码确定与随机接入请求相关联的多模态业务的业务类型。

本实施例中，由于随机接入请求与多模态业务的业务类型相关联，基站在接收到随机接入请求后，可以根据所述随机接入请求确定所述终端请求接入的所述多模态业务的业务类型，并发送针对该业务类型的所述多模态业务的随机接入响应(RAR)，相较于由于终端发送的是未与多模态业务的业务类型相关联的随机接入请求而不能针对该业务类型的多模态业务发送随机接入响应(RAR)的方式，本实施例中，可以针对该业务类型的所述多模态业务发送随机接入响应(RAR)，使得所述多模态业务能够快速接入网络，减少了无针对性地发送随机接入响应(RAR)导致该业务类型的多模态业务长时间不能接入网络的情况，降低了所述多模态业务的时延。
