  • One of the service isolation methods is to divide spectrum resources so that different services are transmitted on different channels. As shown in Figure 1, there are 5 frequency bands in the system, channel 1 to channel 5. Channel 1 to channel 4 are used for common business types; channel 5 is reserved for emergency business types. Similar to emergency corridors in expressways, traditional services must not occupy the red emergency corridors. This method ensures that when an emergency service type occurs, the channel can be accessed at any time, and it is free from interference of ordinary service types.
  • this kind of service isolation design cannot guarantee the system spectrum utilization. If a dedicated channel is allocated for emergency services, the spectrum efficiency of the dedicated channel 5 for emergency services is very low. Ordinary services cannot be offloaded to channel 5 when the other four channels to channel 4 are very busy, resulting in a very low trunking efficiency of the system. Moreover, this service transmission method needs to monitor whether the channel is idle first, and if it is idle, the service can be sent on the channel, which is inefficient. In addition, when an emergency occurs, there may be multiple IoT devices carrying emergency services that need to be transmitted in a system. For example, in the power grid system, some line failures will cause multiple faulty devices to send alarm messages at the same time. At this time, emergency IoT devices cannot occupy other common channels channel 1 to channel 4, so a collision will occur on the emergency channel channel 5, which affects the low latency and high reliability of emergency services.
  • Another service isolation method is to set a higher priority for the emergency service type to give priority to access to the channel.
  • an emergency service occurs, other ordinary services need to be suspended for avoidance.

Description

一种业务处理方法及相关设备 技术领域
本申请涉及通信技术领域，尤其涉及一种业务处理方法及相关设备。
背景技术
物联网IoT(Internet of Things)，是把任何物品与互联网相连接，进行信息交换和通信，以实现智能化识别、定位、跟踪、监控和管理的一种网络概念。换言之，“物联网概念”是在“互联网概念”的基础上，将其用户端延伸和扩展到任何物品与物品之间，进行信息交换和通信的一种网络概念。一般的IoT网络是一个混合网络。例如智能电网中，存在大量的传感以及信息采集类的海量IoT(massive IoT)设备，如电表；也存在任务紧急的IoT设备(mission critical IoT设备)，用于警示和故障汇报，来避免大规模的停电时间造成不可挽回的经济损失和重大事故。Mission critical IoT这类设备与massive IoT不同，这类设备数据发送频率极低，具有偶然性，更注重时延与可靠性。在一些系统或应用场景中，Mission critical IoT设备所承载的业务被称为URLLC(Ultra-Reliable Low-Latency Communication)业务。
在传统IoT业务(非URLLC)与URLLC业务共存的系统中，一般会通过业务隔离的方式，保护URLLC业务的短时延以及高可靠性能。一种业务隔离方式是对频谱资源划分为多个信道，不同类型的业务使用不同的信道传输。但是这种业务隔离型的设计方案无法保证系统频谱利用率。如果为URLLC业务划分专用的信道，则紧急任务URLLC专用通道的频谱效率非常低。普通业务在普通信道非常繁忙时，也无法卸载到专用通道，导致系统的集群效率trunking efficiency非常低。此外，当紧急情况发生时，一个系统中可能会有多个承载URLLC业务的IoT的设备需要进行传输。比如电网系统中，某些线路故障，会导致多个故障设备同时发送报警信息。此时URLLC IoT的设备无法占用其他的普通信道，因此会在专用通道上发生碰撞，影响URLLC业务的低时延和高可靠性能。
另一种业务隔离方式是通过对URLLC设置更高的优先级，可以优先接入信道，URLLC业务发生时，其他传统业务需要暂停进行避让。但是如果是通过让传统业务避让URLLC业务的方式进行业务隔离，则会显著影响传统业务的性能。
因此在不降低系统频谱利用率的前提下，如何保证不同业务的低时延可靠传输，是本领域技术人员正在研究的问题。
发明内容
本申请实施例提供了一种业务处理方法及相关设备，可以在不降低系统频谱利用率的前提下，保证不同业务的低时延可靠传输。
第一方面，本申请提供了一种业务处理方法，包括：网络设备接收第一设备发送的请求消息，所述请求消息包括所述第一设备请求发送的业务类型，或者所述请求消息与所述第一设备请求发送的业务类型对应；所述网络设备为所述请求发送的业务类型分配调制方案；其中，不同的业务类型对应不同的调制方案；所述网络设备将分配的调制方案发送给所述第一设备；所述网络设备在频谱资源上接收来自所述第一设备的业务，所述业务采用 所述分配的调制方案调制；其中，不同业务类型的业务共享所述频谱资源。
实施第一方面所描述的方法，网络设备接收到第一设备发送的请求消息，该请求消息表征了第一设备请求发送的业务类型，网络设备为该业务类型分配调制方案，其中不同的业务类型对应不同的调制方案，然后网络设备将分配的调制方案发送给该第一设备，第一设备接收到调制方案后，采用该调制方案调制业务，将该调制后的业务发送给网络设备，其中，不同业务类型的业务共享同一段频谱资源。通过对不同的业务分配调制方案，使多个业务可以在同一段频谱资源上传输，并且接收端能够正确接收，提高了频谱资源的利用率。
在一种实现方式中，所述不同的业务类型对应不同的调制方案包括以下一种或多种：一种业务类型与一个或多个调制方案对应；不同的业务类型具有优先级，所述业务类型的优先级与一个或多个调制方案对应；不同的业务类型对应不同的设备类型，一种所述设备类型与一个或多个调制方案对应；不同的业务类型具有不同的扩频因子，一种所述扩频因子与一个调制方案对应。这种实现方式提供了业务类型、优先级、设备类型以及扩频因子与调制方案的对应关系，也就是说可以通过业务类型、优先级、设备类型、扩频因子等因素来确定对业务的调制方案，以使不同的业务采用的不同调制方案，不同的业务类型可以共享相同的频谱资源，提高了频谱资源的利用率。
在一种实现方式中，所述网络设备将分配的调制方案发送给所述第一设备包括：所述网络设备通过DCI和/或RRC信令将分配的调制方案发送给所述第一设备。这种实现方式提供了网络设备将分配的调制方案发送给第一设备的可以采用的信令。
在一种实现方式中，不同的调制方案中任意两个调制方案的调制信号的相关性系数低于阈值；或者不同的调制方案中任意两个调制方案的调制信号由于互相干扰而导致的性能损失低于阈值。这种实现方式描述了不同的调制方案的调制信号之间的互不干扰的标准，当两个调制信号的相关性系数低于阈值或者由于互相干扰而导致的性能损失低于阈值，则可以认为这两个调制信号互不干扰，为支持不同的业务类型共享相同的频谱资源提供了前提。
在一种实现方式中，所述频谱资源包括非授权频谱资源。在非授权频谱资源上需要采用先监听后发送的方式，当设备监听到信道空闲时，设备才会发送业务信息，在本申请实施例中，由于不同的业务类型采用的不同调制方案，不同的业务类型可以共享相同的频谱资源，无需采用先监听后发送的方式，提高发送效率，并且节约了资源。

具体实施方式
下面将结合附图对本申请实施例中的技术方案进行清除、详尽地描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；文本中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况，另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为暗示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征，在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执 行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
应当理解，在本申请说明书和所附权利要求书中使用的术语“和/或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合，并且包括这些组合。
首先，为了便于理解本申请实施例，以下具体分析本申请实施例所需要解决的技术问题以及对应的应用场景。在不同的业务类型共存的通信系统中，如果多个业务同时在同一个频谱资源上传输，业务之间会互相干扰，产生性能损失导致接收端无法正确接收，这时一般会通过业务隔离的方式，保护不同的业务类型能够可靠传输。
其中一种业务隔离方式是通过对频谱资源进行划分，使不同的业务在不同的信道上传输，如图1所示，系统中有5个频段，channel 1到channel 5。channel 1到channel 4用于普通业务类型；channel 5专门预留给紧急业务类型。类似于高速公路中的紧急通道，传统业务不得占据红色紧急通道。这种方式保障了紧急业务类型发生时，可以随时接入信道，并且免于普通业务类型的干扰。
然而，这种业务隔离型的设计方案无法保证系统频谱利用率。如果为紧急业务划分专用的信道，则紧急业务专用通道channel 5的频谱效率非常低。普通业务在其他四个channel到channel 4非常繁忙时，也无法卸载到channel 5，导致系统的集群效率trunking efficiency很低。并且，这种业务传输方式需要先监听信道是否空闲，如果空闲才能在该信道上发送业务，效率较低。此外，当紧急情况发生时，一个系统中可能会有多个承载紧急业务的IoT的设备需要进行传输。比如电网系统中，某些线路故障，会导致多个故障设备同时发送报警信息。此时紧急IoT的设备无法占用其他的普通信道channel 1到channel 4，因此会在紧急通道channel 5上发生碰撞，影响紧急业务的低时延和高可靠性能。
另一种业务隔离方式是通过对紧急业务类型设置更高的优先级，可以优先接入信道，紧急业务发生时，其他普通业务需要暂停进行避让。然而这种通过让普通业务避让紧急业务的方式进行业务隔离，则会显著影响普通业务的性能。
因此，针对上述技术问题，本申请主要解决的问题为提供了一种业务处理方法，通过信号隔离的方式，采用不同的调制和/或编码方案将不同业务类型进行隔离，支持不同业务类型的同时接入，在不降低频谱利用率的基础上，保证不同业务类型的可靠传输。

在该通信系统100中，UE 102～107可以发送上行信息给(R)AN 101，(R)AN 101需要接收UE 102～107发送的上行信息，(R)AN 101也可以发送下行信息给UE 102～107，UE 102～107需要接收(R)AN 101发送的下行信息，此外，UE 105～107也可以组成一个通信系统。在该通信系统中，UE 105～107之间可以进行互相收发。

在网络设备和终端设备之间，网络设备接收到终端设备发送的请求发送的业务类型，网络设备为该接收到的业务类型分配调制方案，其中不同的业务类型对应不同的调制方案，然后网络设备将分配的调制方案发送给该终端设备，终端设备接收到调制方案后，采用该调制方案调制业务，将该调制后的业务发送给网络设备，其中，不同业务类型的业务共享同一段频谱资源。
在终端设备和终端设备之间，第二终端设备在频谱资源上发送业务时将采用的第一调制方案广播发送，第一终端设备接收到了第二终端设备采用的第一调制方案后，选择第二调制方案，然后在相同的频谱资源上发送通过第二调制方案调制后的业务，其中第二调制方案与第一调制方案不同。

S302：基站为请求消息中的业务类型分配调制方案。
具体地，基站接收到第一设备发送的请求消息后，获取到第一设备想要发送的业务类型，基站为请求消息中的业务类型分配调制方案，其中不同的业务类型对应不同的调制方案。
可以理解的，调制方案的不同可以是指调制方式的不同，还可以是相同的调制方式下的不同参数的配置。例如调制方式可以是chirp扩频调制、MFSK调制等，相同的调制方式下的不同参数的配置可以是扩频因子为5的chirp扩频信号调制、扩频因子为7的chirp扩频信号调制、扩频因子为8的chirp扩频信号调制等等。举例来说，业务类型与调制方案的对应关系可以如表1所示：

在其中一种实施方式中，不同的业务类型对应不同的调制方案，具体的，不同的业务类型具有优先级，业务类型的优先级与一个或多个调制方案对应。举例来说，不同的业务类型预设不同的优先级，如果需要改变业务类型对应的调制方案，可以通过改变业务类型对应的优先级来改变调制方案，其中优先级与调制方案的对应关系可以如表3所示：
表3
优先级 调制方案
优先级1 SF＝5的chirp扩频调制

在其中一种实施方式中，不同的业务类型对应不同的调制方案，具体的，针对同一种调制方式，例如chirp扩频调制，不同的业务类型具有不同的扩频因子，一种扩频因子与一个调制方案对应。举例来说，不同的业务类型预设不同的扩频因子，基站获取请求消息中的业务类型后，首先确定业务类型的扩频因子，然后根据扩频因子与调制方案的对应关系确定出一个调制方案。
在其中一种实施方式中，调制方案可以包括调制编码方案，即一个调制方案可以包括调制方式和编码方式。举例来说，业务类型与调制方案的对应关系可以如表4所示：

在其中一种实施方式中，网络设备可以通过DCI和/或RRC信令将分配的调制方案发送给第一设备。
S304：第一设备在频谱资源上发送业务，其中，不同业务类型的业务共享频谱资源。
具体地，基站将分配的调制方案发送给第一设备后，第一设备将发送的业务采用分配的调制方案调制，然后发送给基站，基站在频谱资源上接收来自第一设备的业务。其中，不同业务类型的业务共享频谱资源。也即是说，在同一段频谱资源上，第一设备无需监听频谱资源是否空闲，在频谱资源上正在传输其他业务的情况下，第一设备也可以发送采用分配的调制方案调制的业务。
在其中一种实施方式中，上述频谱资源包括非授权频谱资源，现有技术中在非授权频谱资源上需要采用先监听后发送的方式，当设备监听到信道空闲时，设备才会发送业务信息，在本申请实施例中，由于不同的业务类型采用的不同调制方案，不同的业务类型可以共享相同的频谱资源，无需采用先监听后发送的方式，提高发送效率，并且节约了资源。在授权频谱中，本申请实施例同样适用。

可以理解的，调制方案的不同可以是指调制方式的不同，还可以是相同的调制方式下的不同参数的配置。例如调制方式可以是chirp扩频调制、MFSK调制等，相同的调制方式下的不同参数的配置可以是扩频因子为5的chirp扩频信号调制、扩频因子为7的chirp扩频信号调制、扩频因子为8的chirp扩频信号调制等等。

在本申请实施例中，第二终端设备在频谱资源上发送业务时将采用的第一调制方案广播发送，第一终端设备接收到了第二终端设备采用的第一调制方案后，选择第二调制方案，然后在相同的频谱资源上发送通过第二调制方案调制后的业务，其中第二调制方案与第一调制方案不同。通过对不同的业务分配调制方案，使多个业务可以在同一段频谱资源上传输，并能够正确接收，无需采用先监听后发送的方式，提高发送效率，并且节约了资源，提高了频谱资源的利用率。
在上述图3和图4的申请实施例中，不同的调制方案之间的调制信号之间是互不干扰的，即接收端可以正确接收通过不同的调制方案进行调制后，在相同的频谱资源上进行传输的业务。
在其中一种实施方式中，不同的调制方案中任意两个调制方案的调制信号的相关性系数低于阈值；或者不同的调制方案中任意两个调制方案的调制信号由于互相干扰而导致的性能损失低于阈值；就可以认为两个调制信号之间互不干扰。下面分别以这两种方式说明不同的调制信号之间的互不干扰性。
方式一、两个调制方案的调制信号的相关性系数低于阈值。示例性的，以扩频因子SF＝7的chirp扩频信号和扩频因子SF＝8的chirp扩频信号为例，该阈值可以是以dB为单位，如该阈值可以为-15dB，下面详细说明这两个信号之间的相关性。
不同扩频因子SF的chirp扩频调制信号之间具有低互相关性，即较强的抗干扰能力。其中，chirp扩频调制信号具有如下形式：
Figure PCTCN2019130220-appb-000003
其中T s为采样周期，SF为chirp扩频调制信号的扩频因子。
如图5所示，图5描述了在时域上，SF＝8的扩频调制信号对于SF＝7的chirp扩频调制信号的干扰。在时域上SF＝8的扩频调制信号和SF＝7的chirp扩频调制信号发送时间交叉，其中k表示SF＝8的chirp扩频调制符号于SF＝7的chirp扩频调制符号之间的相对时间偏移，SF＝7的chirp扩频调制信号对应的相关器组有128个相关器。互相关性能可通过SF＝8的chirp扩频调制信号经过SF＝7的chirp扩频调制信号的相关器组后的相关值判定。SF＝7的滤波器组中第L(L＝0,…,127)个相关器的形式可以为：

干扰信号SF＝8的chirp扩频调制符号的完整表达为：
Figure PCTCN2019130220-appb-000005
其中m表示选用的SF＝8的chirp扩频调制符号。定义归一化的相关值为SF＝8的干扰信号相关值/正确信号(SF＝7)的相关值γ i，得到

相关值γ i的绝对值为

其中
Figure PCTCN2019130220-appb-000008
由于
Figure PCTCN2019130220-appb-000009
是周期为256的序列，因此遍历κ＝0,1，…，255，将得到所有的相关值‖γ i‖。根据上述公式可以得到数值分析如图6和图7所示，
在图6中，横坐标为时间偏移k，纵坐标为归一化的相关值，可以发现，扩频因子SF＝8的chirp扩频调制符号对于扩频因子SF＝7的chirp扩频调制符号的最大干扰为-17dB，在一些场景下可以等效理解为，当扩频因子SF＝8和SF＝7的chirp扩频调制信号同时发送时，噪声只要不超过17dB，信号可以被正确接收。随着时间偏移K的改变，SF＝8的chirp扩频调制信号于SF＝7的chirp扩频调制信号造成的干扰始终在约-20dB以下。在图7中，横坐标为归一化的相关值，纵坐标为累计概率，显示了SF＝8的chirp扩频调制信号于SF＝7的chirp扩频调制信号所造成所有可能的不同大小的干扰值对应的累积分布概率。可以看出，在-17dB以下，SF＝7的chirp扩频调制信号受到的干扰累积分布概率始终不超过1。因此，SF＝8的chirp扩频调制信号和SF＝7的chirp扩频调制信号相关性系数-17dB不超过阈值-15dB，则可以认为这两个调制方案互不干扰。
同理可以得到SF＝10的chirp扩频调制信号于SF＝9的chirp扩频调制信号造成的干扰 数值分析，如图8所示，横坐标为归一化的相关值，纵坐标为累计概率，显示了SF＝10的chirp扩频调制信号于SF＝9的chirp扩频调制信号所造成所有可能的不同大小的干扰值对应的累积分布概率。可以看出，在-27dB以下，SF＝7的chirp扩频调制信号受到的干扰累积分布概率始终不超过1。因此，SF＝10的chirp扩频调制信号和SF＝8的chirp扩频调制信号相关性系数-27dB不超过阈值-15dB，则可以认为这两个调制方案互不干扰。
结合图表可知，SF越大的chirp扩频调制信号，受到的相对干扰值越小。因此可以对抗更大的干扰，与SF越大工作的信噪比越低的设置匹配。而且根据图9可见，图9描述了不同SF的chirp扩频调制信号的频谱，SF越小，chirp扩频调制符号的频谱局部化/频谱能量集中(frequency localization)越差，或者说频谱带外泄露(out-of-band emissions)越严重，因此为了保证chirp扩频调制信号经过实际系统滤波器后失真较小以及增加信号的抗干扰能力，可以选择相对较大的SF。
方式二、两个调制方案的调制信号由于互相干扰而导致的性能损失低于阈值。示例性地，以chirp扩频信号和MFSK信号为例，该阈值可以是以dB为单位，例如该阈值可以为0.5dB，如图10所示，在时域上chirp扩频信号和MFSK信号的发送时间交叉，MFSK信号解调为DFT(or FFT)接收机，作为干扰信号的chirp扩频调制经过FFT能量分散在所有频点上，而MFSK信号经过FFT后能量聚集于某一频点，处理增益与MFSK信号的数值M成正比。
尽管MFSK信号和Chirp扩频调制信号都是宽带信号，但是将观察窗口限制到一个symbol来说，chirp扩频调制是扩频信号，占满整个系统带宽；而MFSK信号则是单频信号，是窄带信号。也就是说，在频域上来看，若MFSK信号将能量聚集到单个子载波，并通过这个子载波的位置携带信息，而chirp扩频调制信号将能量分散在整个带宽里。因此两类信号同时发送互不干扰，可以提高资源利用率。特别地，在非授权频谱，可以避免进行先监听后发送的机制，节约开销。
进一步地，通过仿真阐述有益效果，假设IoT业务采用chirp扩频调制，其扩频因子SF在7，8，9，10，11，12中随机出现。URLLC业务采用MFSK调制，图中M＝256(符号长度与SF＝8的chirp扩频调制符号相同)。MFSK信号的功率与chirp扩频调制信号的功率比分别为0dB，-3dB，-6dB。如图11所示，相对于没有IoT业务同时接入的情况下，在干扰比SIR＝0dB的干扰下，MFSK的性能损失约为0.1dB。由于性能损失0.1dB小于阈值0.5dB，则可以认为这两个调制方案互不干扰，即传统IoT业务的信号功率接近URLLC业务的信号功率时，二者同时发送对于URLLC业务几乎无影响。
综上所述，以上使用两种方式详细描述了本申请实施例中任意两种调制方案之间是互不干扰的。正是由于调制方案之间互不干扰，则多个不同的业务可以同时在同一段频谱资源中传输而不影响接收端的正确接收。
