背景技术Background technique

在一些应用场景，多个终端设备之间需要协同执行某个业务，这些终端设备需要各自将数据发送到网络侧，由网络侧根据各个终端设备上报的数据进行综合处理。以演唱会场景为例，主唱、贝斯手、吉他手、鼓手等作为终端设备，这些终端设备属于同一个混音组(也可以称为用户组)，需要分别通过移动网络将各自产生的声音数据发送至网络侧，然后网络侧根据收集的各个声音数据按照确定性时间(deterministic time)进行混音处理，从而将最终的处理结果进行输出，并返回给各个终端设备。In some application scenarios, multiple terminal devices need to perform a certain service in coordination, and these terminal devices need to send data to the network side, and the network side performs comprehensive processing based on the data reported by each terminal device. Taking the concert scene as an example, the vocalist, bassist, guitarist, drummer, etc. are used as terminal devices. These terminal devices belong to the same mixing group (also called user group), and the sound data generated by each needs to be separately generated through the mobile network. Send to the network side, and then the network side performs mixing processing according to the deterministic time according to each collected sound data, so as to output the final processing result and return it to each terminal device.

同一个混音组中，由于网络侧是按照确定性时间来处理接收到的数据，因此需要各个终端设备发送的数据在确定的某个时间范围内到达，否则一旦某个或某些终端设备发送的数据没有在确定的时间范围内到达，就无法执行混音处理，并且网络侧将会丢弃从其他终端设备接收到的数据，最终导致混音失败。In the same mixing group, because the network side processes the received data according to the deterministic time, the data sent by each terminal device needs to arrive within a certain time range, otherwise once one or some terminal devices send If the data does not arrive within a certain time range, the audio mixing process cannot be performed, and the network side will discard the data received from other terminal devices, which will eventually cause the audio mixing to fail.

因此，如何优化确定性媒体传输中的时延，以提升数据处理的质量，是有待解决的问题。Therefore, how to optimize the delay in deterministic media transmission to improve the quality of data processing is a problem to be solved.

无线音频***是使用无线电波代替有线方式传输音频信号的***。无线音频***通常包括无线传声器***和无线返听***，也包括在一些特定场合中通过无线方式进行远距离音频传输的***。无线音频***在当下的大型演出中已成为必不可少的子***。A wireless audio system is a system that uses radio waves instead of wired to transmit audio signals. Wireless audio systems usually include wireless microphone systems and wireless back-to-back systems, as well as systems that carry out long-distance audio transmission wirelessly in some specific occasions. The wireless audio system has become an indispensable subsystem in today's large-scale performances.

无线音频***可以应用于大型音乐会、演唱会等场景，无线音频***对于端到端时延(lateny)、传输周期、安全性可靠性以及声音的质量具有较高的要求。The wireless audio system can be applied to scenes such as large-scale concerts and concerts. The wireless audio system has higher requirements for end-to-end delay (lateny), transmission period, safety and reliability, and sound quality.

如图2所示，为专业音频制作通信***中涉及的组成部分示意图。一方面，该***包括无线音频输入，在此将其表示为麦克风。在音频源处捕获音频，并通过无线连接发送到混音处理服务器，该服务器可以执行几种音频输入的混合，代码转换，均衡或其他处理任务。音频处理的结果通过无线连接发送至输出设备，该输出设备可以是扬声器，配备耳机的通用设备或其他设备。As shown in Figure 2, it is a schematic diagram of the components involved in the professional audio production communication system. On the one hand, the system includes a wireless audio input, which is denoted here as a microphone. The audio is captured at the audio source and sent to the mixing processing server through a wireless connection, which can perform the mixing, transcoding, equalization, or other processing tasks of several audio inputs. The result of the audio processing is sent to an output device via a wireless connection, which can be a speaker, a general-purpose device equipped with headphones, or other devices.

比如，在实际演出过程中，通常是多个输入设备生成声源数据，如在一个音乐会演出活动中，有贝斯手，吉他手，架子鼓手以及主唱，他们每一个人的输入设备都是整场演出必不可少的声源数据。所有的声源数据再通过接入网设备发送到网络侧的混音处理服务器做合音或混音处理。当不同的UE发送上行数据时，接入网设备独立进行调度，为不同的UE分配不同的空口调度资源(其中，空口调度资源包括时间资源和频率资源，时间资源可以用时间单元如时隙(slot)、迷你时隙(mini-slot)来表示)，混音处理服务器将输入的不同声源数据进行混音处理，然后将混音后的效果通过接入网设备发送到每一个表演者的耳返设备中，这样每一个表演者就能听到现场表演的效果。混音处理服务器一般需要等到同一混音组(也称为用户组)的UE的上行数据都到达时，才开始进行混音。也即，在同一个混音组中，网络侧是按照确定性时间来处理接收到的数据，因此必须限定各个UE发送的数据需要在确定的某个时间范围内到达，否则一旦某个或某些UE的数据没有在确定的时间范围内到达，就无法执行混音处理，网络侧将会丢弃从其他UE接收到的数据，最终导致混音失败。For example, in the actual performance process, multiple input devices usually generate sound source data. For example, in a concert performance, there are bassists, guitarists, drummers, and vocals. Each of them has a complete input device. Sound source data essential for a performance. All the sound source data is then sent to the mixing processing server on the network side through the access network device for sound mixing or mixing processing. When different UEs send uplink data, the access network equipment performs independent scheduling and allocates different air interface scheduling resources to different UEs (where air interface scheduling resources include time resources and frequency resources, and time resources can be used in time units such as time slots ( slot), mini-slot (mini-slot), the mixing processing server mixes the input data of different sound sources, and then sends the mixed effect to each performer through the access network equipment. In the ear-return device, every performer can hear the effect of the live performance. The audio mixing processing server generally needs to wait until the uplink data of the UEs in the same audio mixing group (also referred to as the user group) arrive before starting audio mixing. That is, in the same mixing group, the network side processes the received data according to the deterministic time. Therefore, it must be restricted that the data sent by each UE needs to arrive within a certain time range, otherwise once a certain or a certain If the data of some UEs does not arrive within a certain time range, the audio mixing process cannot be performed, and the network side will discard the data received from other UEs, resulting in audio mixing failure.

现有机制中，属于同一个混音组的多个UE需要通过接入网设备发送上行数据时，需要分别按照接入网设备分配的空口调度资源来传输上行数据。同一个混音组的不同UE被分配的空口调度资源中的时间资源可能处于相隔较远的时间单元，导致不同的UE发送的上行数据到达混音处理服务器的时延相差较大。也即，现有机制无法保证同一混音组的UE发送的上行数据的确定性传输时延，因而可能导致混音处理服务器混音失败。In the existing mechanism, when multiple UEs belonging to the same audio mixing group need to transmit uplink data through the access network device, they need to transmit the uplink data according to the air interface scheduling resources allocated by the access network device. The time resources in the air interface scheduling resources allocated to different UEs of the same audio mixing group may be in time units that are far apart, resulting in a large difference in the time delay for uplink data sent by different UEs to reach the audio mixing processing server. That is, the existing mechanism cannot guarantee the deterministic transmission delay of uplink data sent by UEs in the same audio mixing group, which may result in audio mixing failure of the audio mixing processing server.

如图3所示，为多个UE在发送上行数据时产生时延的示意图。假设UE1和UE2已经做了时间同步(二者的时间相同)，UE1的上行数据与UE2的上行数据在发送时，尽管UE1的硬件设备和UE2的硬件设备可以保证各自在相同时间点生成数据，但是RAN设备为UE1和UE2分配的时间单元可能不一样并且相隔较远，这样在空口传输过程中，UE1的上行数据可能早于UE2的上行数据发送，因此二者虽然是通过同一个RAN设备发送，但是却不在相同或相邻的时间单元调度。这样导致UE1的上行数据和UE2的上行数据之间产生了较大时延。此外，后续RAN设备在传输UE1和UE2的上行数据的时候，网络侧的传输路径也可能额外引入时延，混音器设备接收UE1的上行数据和UE2的上行数据之间的时延可能会发生累积，造成时延进一步增大。As shown in FIG. 3, it is a schematic diagram of a delay caused by multiple UEs when sending uplink data. Assuming that UE1 and UE2 have been time synchronized (the time of the two is the same), the uplink data of UE1 and the uplink data of UE2 are sent, although the hardware equipment of UE1 and the hardware equipment of UE2 can ensure that they generate data at the same time point. However, the time units allocated by the RAN equipment for UE1 and UE2 may be different and far apart. In this way, during the air interface transmission, the uplink data of UE1 may be sent earlier than the uplink data of UE2, so although the two are sent through the same RAN device , But it is not scheduled in the same or adjacent time unit. This results in a large time delay between the uplink data of UE1 and the uplink data of UE2. In addition, when the subsequent RAN equipment transmits the uplink data of UE1 and UE2, the transmission path on the network side may also introduce additional time delay, and the time delay between the uplink data of UE1 and the uplink data of UE2 may occur between the mixer equipment. Accumulate, causing the time delay to increase further.

为解决上述问题，基于图1A或图1B所示的网络架构，如图4所示，本申请实施例提供一种资源分配方法。该方法在RAN侧，可以由RAN设备或用于RAN设备的部件(如芯片、电路等)执行；在网络侧，可以由SMF或用于SMF的部件(如芯片、电路等)执行。为便于说明，下面以RAN设备和SMF执行该方法为例进行说明。To solve the above problem, based on the network architecture shown in FIG. 1A or FIG. 1B, as shown in FIG. 4, an embodiment of the present application provides a resource allocation method. On the RAN side, this method can be executed by RAN equipment or components (such as chips, circuits, etc.) used for RAN equipment; on the network side, it can be executed by SMF or components (such as chips, circuits, etc.) used for SMF. For ease of description, the following uses the RAN device and the SMF to execute the method as an example for description.

该方法包括以下步骤：The method includes the following steps:

步骤401，SMF接收用户组的标识。Step 401: The SMF receives the identifier of the user group.

该用户组的标识用于指示至少两个UE。可选的，该用户组也可以称为同步调度业务组、同步调度组等。The identifier of the user group is used to indicate at least two UEs. Optionally, the user group may also be referred to as a synchronous scheduling service group, a synchronous scheduling group, and so on.

该用户组内的任意一个UE需要与该用户组内的其他UE同步的空口调度资源。或者理解为，该用户组内的UE相互之间具有同步的空口调度资源的需求。或者理解为，该用户组内的UE相互之间具有同步调度的需求。其中，同步的空口调度资源指的是，为同一用户组内的UE分配的空口调度资源处于相同或相邻的时间单元。Any UE in the user group needs air interface scheduling resources synchronized with other UEs in the user group. Or it can be understood that the UEs in the user group have requirements for synchronized air interface scheduling resources with each other. Or it can be understood that the UEs in the user group have synchronization scheduling requirements with each other. Wherein, the synchronized air interface scheduling resource refers to that the air interface scheduling resources allocated to UEs in the same user group are in the same or adjacent time units.

本申请实施例中，时间单元可以是时隙(slot)、或迷你时隙(mini-slot)，这里统一说明，后续不再赘述。In the embodiment of the present application, the time unit may be a slot or a mini-slot, which will be described in a unified manner here, and will not be repeated in the following.

作为一种实现方式，SMF可以接收来自第一UE的用户组的标识，该第一UE属于该用户组。也即，第一UE请求分配空口调度资源，同时携带自己所属的用户组的标识。As an implementation manner, the SMF may receive the identity of the user group from the first UE, and the first UE belongs to the user group. That is, the first UE requests the allocation of air interface scheduling resources, and at the same time carries the identity of the user group to which it belongs.

作为又一种实现方式，SMF可以接收来自AF的UE列表和用户组的标识。也即，AF 请求为UE列表的各个UE分配空口调度资源，同时携带该UE列表的各个UE所属的用户组的标识。As yet another implementation manner, the SMF can receive the UE list and user group identifiers from the AF. That is, the AF requests the allocation of air interface scheduling resources for each UE in the UE list, and at the same time carries the identifier of the user group to which each UE in the UE list belongs.

步骤402，SMF根据用户组的标识，确定同步调度指示信息，该同步调度指示信息用于指示所述用户组内的UE需要与所述用户组内的其它UE同步的空口调度资源。Step 402: The SMF determines synchronization scheduling indication information according to the user group identifier, and the synchronization scheduling indication information is used to indicate that the UE in the user group needs to synchronize air interface scheduling resources with other UEs in the user group.

作为一种实现方式，SMF上可以预先配置每一个用户组的标识与同步调度指示信息之间的对应关系。SMF获取用户组的标识之后，SMF可以根据用户组的标识，确定对应的同步调度指示信息。As an implementation manner, the corresponding relationship between the identifier of each user group and the synchronization scheduling indication information can be pre-configured on the SMF. After the SMF obtains the identifier of the user group, the SMF can determine the corresponding synchronization scheduling indication information according to the identifier of the user group.

作为又一种实现方式，SMF上可以预先配置用户组的标识列表与同步调度指示信息之间的对应关系。用户组的标识列表包含至少一个用户组的标识。如果SMF获取的用户组的标识属于该列表内，那么SMF可以确定对应的同步调度指示信息。As yet another implementation manner, the corresponding relationship between the identification list of the user group and the synchronization scheduling indication information can be pre-configured on the SMF. The user group identifier list contains at least one user group identifier. If the identifier of the user group obtained by the SMF belongs to the list, the SMF can determine the corresponding synchronization scheduling indication information.

作为又一种实现方式，SMF还可以通过其他网元(例如PCF网元)获取用户组的标识与同步调度指示信息之间的对应关系，本申请实施例不做限定。需要说明的是，同一个用户组内的UE可以对应相同的同步调度指示信息。As yet another implementation manner, the SMF may also obtain the correspondence between the identifier of the user group and the synchronization scheduling indication information through other network elements (for example, a PCF network element), which is not limited in the embodiment of the present application. It should be noted that UEs in the same user group can correspond to the same synchronization scheduling indication information.

步骤403，SMF向RAN发送同步调度指示信息。相应的，RAN可以接收到该同步调度指示信息。Step 403: The SMF sends synchronization scheduling indication information to the RAN. Correspondingly, the RAN can receive the synchronization scheduling indication information.

步骤404，RAN根据同步调度指示信息，为UE分配空口调度资源。其中，该空口调度资源用于UE发送上行数据。Step 404: The RAN allocates air interface scheduling resources for the UE according to the synchronization scheduling indication information. Wherein, the air interface scheduling resource is used for the UE to send uplink data.

需要说明的是，若上述步骤401中，SMF是从第一UE接收到用户组的标识，则该步骤404中，RAN具体为该第一UE分配空口调度资源。若上述步骤401中，SMF是从AF接收到用户组的标识，则该步骤404中，RAN具体为该用户组内的所有UE依次分配空口调度资源。可以理解为，SMF根据用户组内UE的数量多次执行步骤403，即用户组内UE的数量为多个，SMF向RAN多次发送同步调度指示信息，其中，每一个同步调度指示信息均与用户组内的每一个UE关联，RAN根据同步调度指示信息，为每一个UE分配空口调度资源。It should be noted that, if in step 401, the SMF is the identifier of the user group received from the first UE, then in step 404, the RAN specifically allocates air interface scheduling resources for the first UE. If in step 401, the SMF is the identifier of the user group received from the AF, then in step 404, the RAN specifically allocates air interface scheduling resources to all UEs in the user group in sequence. It can be understood that the SMF performs step 403 multiple times according to the number of UEs in the user group, that is, the number of UEs in the user group is multiple, and the SMF sends synchronization scheduling indication information to the RAN multiple times, where each synchronization scheduling indication information is the same as Each UE in the user group is associated, and the RAN allocates air interface scheduling resources for each UE according to the synchronization scheduling indication information.

RAN为UE分配空口调度资源的方式，比如可以是：The way that the RAN allocates air interface scheduling resources to the UE may be, for example:

方法一，RAN根据同步调度指示信息从空闲资源中，为UE在分配空口调度资源。Method 1: The RAN allocates air interface scheduling resources for the UE from idle resources according to the synchronization scheduling indication information.

比如，RAN根据接收到的同步调度指示信息，确定该UE是用户组内的第一个请求分配空口调度资源的UE，或者，RAN确定之前未收到过与所述用户组内的UE关联的同步调度指示信息，则RAN可以按照正常流程分配空口调度资源，比如按照现有技术中的资源分配方式，从空闲资源中为该UE分配空口调度资源，即RAN根据自身的资源分配情况确定该UE的上行数据调度的时间单元，并给UE发送资源调度指派(Grant)，通知UE在某个时间单元发送该上行数据。同时RAN本地保存该同步调度指示信息与该调度资源的对应关系。后续UE将上行数据按照RAN分配的空口调度资源发送给RAN。在为UE分配空口调度资源之后，RAN还可以为用户组内的其他UE分配预留资源，该预留资源与已经分配给该UE的空口调度资源处于相同或相邻的时间单元。即，该预留资源适用于用户组内的其他UE。For example, according to the received synchronization scheduling indication information, the RAN determines that the UE is the first UE in the user group to request the allocation of air interface scheduling resources, or the RAN determines that it has not received any information associated with the UE in the user group before. Synchronize scheduling indication information, the RAN can allocate air interface scheduling resources according to the normal process, for example, according to the resource allocation method in the prior art, allocate air interface scheduling resources from idle resources to the UE, that is, the RAN determines the UE according to its own resource allocation. The time unit for uplink data scheduling, and sends a resource scheduling assignment (Grant) to the UE to notify the UE to send the uplink data in a certain time unit. At the same time, the RAN locally stores the corresponding relationship between the synchronization scheduling indication information and the scheduling resource. Subsequently, the UE sends the uplink data to the RAN according to the air interface scheduling resources allocated by the RAN. After allocating air interface scheduling resources for the UE, the RAN may also allocate reserved resources for other UEs in the user group, where the reserved resources are in the same or adjacent time unit as the air interface scheduling resources allocated to the UE. That is, the reserved resources are applicable to other UEs in the user group.

需要说明的是，RAN确定该UE是用户组内的第一个请求分配空口调度资源的UE或者RAN确定之前未收到过与所述用户组内的UE关联的同步调度指示信息，指的是，在某个时间范围内(比如，以演唱会场景为例，主唱、贝斯手、吉他手、鼓手等作为用户组内的UE具有空口调度同步需求，在一场演唱会的开始到结束的时间范围内等)RAN确定之前未收到过与所述用户组内的UE关联的同步调度指示信息。基于该实现方式，可以对一个时间范围内的多个设备(如媒体设备)发送数据的空口调度资源进行统一调度和分配，从而可以实现减少确定性传输中的时延。It should be noted that if the RAN determines that the UE is the first UE in the user group to request the allocation of air interface scheduling resources or the RAN determines that it has not received the synchronization scheduling indication information associated with the UE in the user group before, it refers to , In a certain time range (for example, taking a concert scene as an example, the vocalist, bassist, guitarist, drummer, etc., as UEs in the user group have air-interface scheduling synchronization requirements, and the time from the beginning to the end of a concert Within range, etc.) The RAN determines that the synchronization scheduling indication information associated with the UE in the user group has not been received before. Based on this implementation manner, the air interface scheduling resources for sending data of multiple devices (such as media devices) within a time range can be uniformly scheduled and allocated, so that the delay in deterministic transmission can be reduced.

再比如，RAN根据接收到的同步调度指示信息确定该UE不是用户组内的第一个请求分配空口调度资源的UE，或者，RAN确定之前收到过与所述用户组内的UE关联的同步调度指示信息，则RAN可以从该预留资源中，为该UE分配空口调度资源。For another example, the RAN determines that the UE is not the first UE in the user group to request the allocation of air interface scheduling resources according to the received synchronization scheduling indication information, or the RAN determines that it has previously received synchronization associated with UEs in the user group. According to the scheduling indication information, the RAN can allocate air interface scheduling resources for the UE from the reserved resources.

需要说明的是，RAN确定该UE不是用户组内的第一个请求分配空口调度资源的UE或者RAN确定之前收到过与所述用户组内的UE关联的同步调度指示信息，指的是，在某个时间范围内(比如，以演唱会场景为例，主唱、贝斯手、吉他手、鼓手等作为用户组内的UE具有空口调度同步需求，在一场演唱会的开始到结束的时间范围内等)RAN确定之前收到过与所述用户组内的UE关联的同步调度指示信息。It should be noted that the RAN determines that the UE is not the first UE in the user group to request the allocation of air interface scheduling resources or the RAN determines that it has previously received synchronization scheduling indication information associated with the UEs in the user group, which refers to: In a certain time range (for example, taking a concert scene as an example, the UE in the user group as the lead singer, bassist, guitarist, drummer, etc., has air-interface scheduling synchronization requirements, and the time range from the beginning to the end of a concert (Internal etc.) The RAN determines that it has previously received synchronization scheduling indication information associated with the UE in the user group.

方法二，RAN根据同步调度指示信息从用户组对应的空口资源中，为该UE分配空口调度资源。Method 2: The RAN allocates air interface scheduling resources for the UE from the air interface resources corresponding to the user group according to the synchronization scheduling indication information.

这里的空口资源可以是RAN上配置的与用户组对应的固定调度资源，或者空口资源也可以是用户组内的UE发起注册流程时，RAN为该用户组分配的固定调度资源。The air interface resource here may be a fixed scheduling resource corresponding to the user group configured on the RAN, or the air interface resource may also be a fixed scheduling resource allocated by the RAN to the user group when the UE in the user group initiates the registration process.

比如，RAN根据接收到的同步调度指示信息，确定该UE是用户组内的第一个请求分配空口调度资源的UE，或者，RAN确定之前未收到过与所述用户组内的UE关联的同步调度指示信息，则RAN可以从该用户组对应的空口资源中为该UE分配空口调度资源，即RAN根据自身的资源分配情况确定该UE的上行数据调度的时间单元，并给UE发送资源调度指派(Grant)，通知UE在某个时间单元发送该上行数据。后续UE将上行数据按照RAN分配的资源发送给RAN。在为UE分配空口调度资源之后，RAN还可以为用户组内的其他UE分配预留资源，该预留资源是上述空口资源中的资源，且与已经分配给该UE的资源处于相同或相邻的时间单元。即，该预留资源适用于用户组内的其他UE。For example, according to the received synchronization scheduling indication information, the RAN determines that the UE is the first UE in the user group to request the allocation of air interface scheduling resources, or the RAN determines that it has not received any information associated with the UE in the user group before. Synchronize scheduling indication information, the RAN can allocate air interface scheduling resources for the UE from the air interface resources corresponding to the user group, that is, the RAN determines the time unit for uplink data scheduling of the UE according to its own resource allocation, and sends resource scheduling to the UE Assignment (Grant) informs the UE to send the uplink data in a certain time unit. Subsequently, the UE sends the uplink data to the RAN according to the resources allocated by the RAN. After allocating air interface scheduling resources for the UE, the RAN can also allocate reserved resources for other UEs in the user group. The reserved resources are the resources in the above air interface resources and are the same as or adjacent to the resources already allocated to the UE. Time unit. That is, the reserved resources are applicable to other UEs in the user group.

需要说明的是，RAN确定该UE是用户组内的第一个请求分配空口调度资源的UE或者RAN确定之前未收到过与所述用户组内的UE关联的同步调度指示信息，指的是，在某个时间范围内(比如，以演唱会场景为例，主唱、贝斯手、吉他手、鼓手等作为用户组内的UE具有空口调度同步需求，在一场演唱会的开始到结束的时间范围内等)RAN确定之前未收到过与所述用户组内的UE关联的同步调度指示信息。It should be noted that if the RAN determines that the UE is the first UE in the user group to request the allocation of air interface scheduling resources or the RAN determines that it has not received the synchronization scheduling indication information associated with the UE in the user group before, it refers to , In a certain time range (for example, taking a concert scene as an example, the vocalist, bassist, guitarist, drummer, etc., as UEs in the user group have air-interface scheduling synchronization requirements, and the time from the beginning to the end of a concert Within range, etc.) The RAN determines that the synchronization scheduling indication information associated with the UE in the user group has not been received before.

作为一个示例，UE1和UE2属于同一个用户组。比如，UE1是用户组内的第一个请求分配空口调度资源的UE，则RAN可以从空闲资源或用户组对应的空口资源中为UE1分配空口调度资源，同时还分配预留资源，该预留资源与为UE1分配的调度资源处于相同或相邻的时间单元。后续，UE2再请求分配空口调度资源，则RAN可以在上述预留资源上为UE2分配空口调度资源。从而实现了为处于同一个用户组的UE分配处于相同或相邻时间单元的调度资源。As an example, UE1 and UE2 belong to the same user group. For example, if UE1 is the first UE in the user group to request the allocation of air interface scheduling resources, the RAN can allocate air interface scheduling resources to UE1 from idle resources or air interface resources corresponding to the user group, and also allocate reserved resources. The resource and the scheduling resource allocated for UE1 are in the same or adjacent time unit. Subsequently, UE2 requests the allocation of air interface scheduling resources again, and the RAN can allocate air interface scheduling resources for UE2 on the above reserved resources. In this way, the scheduling resources in the same or adjacent time units are allocated to UEs in the same user group.

例如，参考图5A和图5B，为分配空口调度资源的示意图。图5A中，在空口侧为UE1和UE2分配的调度资源处于相同的时间单元。图5B中，为UE1和UE2分配的调度资源处于相邻的时间单元。For example, referring to FIG. 5A and FIG. 5B, schematic diagrams of allocating air interface scheduling resources. In FIG. 5A, the scheduling resources allocated to UE1 and UE2 on the air interface side are in the same time unit. In FIG. 5B, the scheduling resources allocated to UE1 and UE2 are in adjacent time units.

参考图5A，假设UE1是用户组内的第一个请求分配空口调度资源的UE，则RAN从空闲资源(针对上述方法一)或用户组对应的空口资源(针对上述方法二)中为UE1分配空口调度资源，然后从空闲资源(针对上述方法一)或用户组对应的空口资源(针对上述方法二)中分配预留资源，该预留资源与为UE1分配空口调度资源处于相同的时间单元，此时，该预留资源包括图5A中所示的为UE2分配的空口调度资源和图5A中所示的预留资源。后续，用户组内UE2(即用户组内的第二个请求分配空口调度资源的UE)请求分配空口调度资源，则RAN从上述预留资源中为UE2分配空口调度资源，为UE2分配空口调度资源如图5A所示，与为UE1分配空口调度资源处于相同的时间单元，此时剩下的预留资源如图5A所示。Referring to FIG. 5A, assuming that UE1 is the first UE in the user group to request the allocation of air interface scheduling resources, the RAN allocates UE1 from idle resources (for the above method 1) or the air interface resources corresponding to the user group (for the above method 2) Air interface scheduling resources, and then allocate reserved resources from idle resources (for the above method 1) or air interface resources corresponding to the user group (for the above method 2), and the reserved resources are in the same time unit as the air interface scheduling resources allocated for UE1, At this time, the reserved resources include the air interface scheduling resources allocated to UE2 shown in FIG. 5A and the reserved resources shown in FIG. 5A. Subsequently, UE2 in the user group (that is, the second UE in the user group that requests the allocation of air interface scheduling resources) requests the allocation of air interface scheduling resources, and the RAN allocates air interface scheduling resources for UE2 from the above reserved resources, and allocates air interface scheduling resources for UE2 As shown in FIG. 5A, it is in the same time unit as the allocation of air interface scheduling resources for UE1, and the remaining reserved resources at this time are shown in FIG. 5A.

参考图5B，假设UE1是用户组内的第一个请求分配空口调度资源的UE，则RAN从空闲资源(针对上述方法一)或用户组对应的空口资源(针对上述方法二)中为UE1分配空口调度资源，然后从空闲资源(针对上述方法一)或用户组对应的空口资源(针对上述方法二)中分配预留资源，该预留资源与为UE1分配空口调度资源处于相同或相邻的时间单元，此时，该预留资源包括图5B中所示的为UE2分配的空口调度资源和图5B中所示的预留资源。后续，用户组内UE2(即用户组内的第二个请求分配空口调度资源的UE)请求分配空口调度资源，则RAN从上述预留资源中为UE2分配空口调度资源，为UE2分配空口调度资源如图5B所示，与为UE1分配空口调度资源处于相邻的时间单元，此时剩下的预留资源如图5B所示。Referring to Figure 5B, assuming that UE1 is the first UE in the user group to request the allocation of air interface scheduling resources, the RAN allocates UE1 from idle resources (for the above method 1) or the air interface resources corresponding to the user group (for the above method 2) Air interface scheduling resources, and then allocate reserved resources from idle resources (for the above method 1) or air interface resources corresponding to the user group (for the above method 2), and the reserved resources are the same as or adjacent to the air interface scheduling resources allocated for UE1 Time unit. At this time, the reserved resources include the air interface scheduling resources allocated to UE2 shown in FIG. 5B and the reserved resources shown in FIG. 5B. Subsequently, UE2 in the user group (that is, the second UE in the user group that requests the allocation of air interface scheduling resources) requests the allocation of air interface scheduling resources, and the RAN allocates air interface scheduling resources for UE2 from the above reserved resources, and allocates air interface scheduling resources for UE2 As shown in FIG. 5B, the time unit is adjacent to the allocation of air interface scheduling resources for UE1, and the remaining reserved resources at this time are shown in FIG. 5B.

可选的，若上述步骤401中，SMF是从第一UE接收到用户组的标识，则上述步骤403中，SMF还可以向RAN发送第一UE的PDU会话的标识，该PDU会话是与上述用户组内的第一UE执行的同步业务相关联的会话。进而，该步骤404中，RAN根据同步调度指示信息，为第一UE的该PDU会话分配空口调度资源。Optionally, if in the above step 401, the SMF is the identifier of the user group received from the first UE, then in the above step 403, the SMF may also send the identifier of the PDU session of the first UE to the RAN, and the PDU session is with the above The session associated with the synchronization service performed by the first UE in the user group. Furthermore, in this step 404, the RAN allocates air interface scheduling resources for the PDU session of the first UE according to the synchronization scheduling indication information.

可选的，若上述步骤401中，SMF是从AF接收到用户组的标识以及UE列表，则上述步骤403中，SMF还可以根据UE列表确定UE列表内的各个UE分别对应的PDU会话，并向RAN发送UE列表内的各个UE分别对应的PDU会话的标识，其中，SMF根据UE列表内的UE数量向RAN多次发送UE列表内的各个UE分别对应的PDU会话的标识，该PDU会话是与上述用户组内的UE执行的同步业务相关联的会话。进而，该步骤404中，RAN根据同步调度指示信息，为UE列表内的各个UE分别对应的PDU会话分配空口调度资源。Optionally, if in step 401, the SMF is the user group identifier and the UE list received from the AF, then in step 403, the SMF may also determine the PDU session corresponding to each UE in the UE list according to the UE list, and Send the PDU session identifier corresponding to each UE in the UE list to the RAN. The SMF sends the PDU session identifier corresponding to each UE in the UE list to the RAN multiple times according to the number of UEs in the UE list. The PDU session is A session associated with the synchronization service performed by the UE in the above-mentioned user group. Furthermore, in this step 404, the RAN allocates air interface scheduling resources to the PDU sessions corresponding to each UE in the UE list according to the synchronization scheduling indication information.

例如，UE1和UE2属于同一个用户组，RAN为UE1和UE2分配空口调度资源的示意图可参考图5A和图5B。后续当UE1和UE2发送上行数据时，RAN对UE1和UE2分别发送的上行数据的调度示意图可参考图6，如果RAN在分配空口调度资源时，将UE1和UE2的上行数据放在同一个时间单元或相邻时间中进行调度，则可以尽量地保证UE1和UE2的上行数据同时传输到网络侧，这样网络进行混音处理的时候，可以尽可能地同时收到UE1和UE2的上行数据，从而有助于保证混音处理的效果和质量。For example, UE1 and UE2 belong to the same user group, and the schematic diagram of RAN allocating air interface scheduling resources to UE1 and UE2 can refer to FIG. 5A and FIG. 5B. Subsequent when UE1 and UE2 send uplink data, the RAN scheduling diagram of the uplink data sent by UE1 and UE2 respectively can refer to Figure 6. If the RAN allocates air interface scheduling resources, the uplink data of UE1 and UE2 are placed in the same time unit. Or scheduling in adjacent time, you can try to ensure that the uplink data of UE1 and UE2 are transmitted to the network side at the same time, so that when the network is performing mixing processing, it can receive the uplink data of UE1 and UE2 as much as possible. Helps ensure the effect and quality of the mixing process.

上述方案中，网络侧(SMF)可以基于用户组的标识确定RAN侧的同步调度指示信息，RAN可以根据该同步调度指示信息为用户组内的UE分配相同或相邻时间单元的空口调度资源，从而网络侧可以在尽可能短的时延内接收到用户组内的不同UE发送的数据，有助于提升数据处理的质量。In the above solution, the network side (SMF) can determine the synchronization scheduling indication information on the RAN side based on the identity of the user group, and the RAN can allocate the air interface scheduling resources of the same or adjacent time unit to the UEs in the user group according to the synchronization scheduling indication information. Therefore, the network side can receive the data sent by different UEs in the user group within the shortest possible time delay, which helps to improve the quality of data processing.

下面结合具体示例，对上述图4所示的流程进行介绍说明。The following describes the process shown in FIG. 4 in combination with specific examples.

如图7所示，为本申请实施例提供的又一种资源分配方法流程示意图。该方案中，UE向网络发送自身所在的用户组的标识。网络可以基于用户组的标识分配同步调度指示信息，并将同步调度指示信息发送给RAN，如此，RAN可以根据同步调度指示信息为该UE进行特殊的资源调度，即对处于同一用户组的UE进行资源的同步调度。As shown in FIG. 7, it is a schematic flowchart of another resource allocation method provided by an embodiment of this application. In this solution, the UE sends the identity of the user group in which it is located to the network. The network can allocate synchronization scheduling indication information based on the identity of the user group, and send the synchronization scheduling indication information to the RAN. In this way, the RAN can perform special resource scheduling for the UE according to the synchronization scheduling indication information, that is, perform special resource scheduling for UEs in the same user group. Synchronous scheduling of resources.

该方案的前提条件是：多个UE加入到同一个用户组并均获取到相同的组标识(group ID)，比如该组标识可以是用户组标识(UE group ID)(也可以称为用户组的标识)或者业务组标识(serice group ID)(也可以称为业务组的标识)，该组标识用于标识一组特定的UE，组内的每一个UE具备相同的业务类型(如媒体业务)，或者相同的业务需求(如同步调度需求)等等，本申请实施例不做限定。The prerequisite of this solution is that multiple UEs join the same user group and all obtain the same group ID. For example, the group ID can be a user group ID (UE group ID) (also called a user group). ID) or service group ID (also called service group ID). The group ID is used to identify a specific group of UEs. Each UE in the group has the same service type (such as media service). ), or the same business requirements (such as synchronization scheduling requirements), etc., which are not limited in the embodiment of the present application.

可选的，UE获取组标识的方法包括但不限于以下两种：Optionally, the methods for the UE to obtain the group identity include but are not limited to the following two:

a)在注册流程中，网络根据UE的签约数据生成(如，根据UE签约的业务类型生成组标识)，或者UE的签约数据中包含了该UE所属的组标识，然后在注册接受消息中，由网络发送给UE。a) In the registration process, the network generates according to the UE's subscription data (for example, generates a group ID according to the service type that the UE subscribes to), or the UE's subscription data contains the group ID to which the UE belongs, and then in the registration acceptance message, Sent by the network to the UE.

b)UE上本地配置该UE所属的组标识。b) The group identity to which the UE belongs is configured locally on the UE.

以组标识为用户组标识为例，该方法包括以下步骤：Taking the group ID as the user group ID as an example, the method includes the following steps:

步骤701，UE向AMF发送第一请求。相应的，AMF可以接收到该第一请求。Step 701: The UE sends a first request to the AMF. Correspondingly, the AMF can receive the first request.

该第一请求包含PDU会话的标识(PDU session ID)以及用户组标识,PDU会话的标识用于标识该PDU会话。该用户组内的任意一个UE需要与该用户组内的其他UE同步的空口调度资源。The first request includes the PDU session ID (PDU session ID) and the user group ID, and the PDU session ID is used to identify the PDU session. Any UE in the user group needs air interface scheduling resources synchronized with other UEs in the user group.

该步骤701中发送第一请求的UE，属于该用户组。The UE that sends the first request in step 701 belongs to the user group.

作为该步骤701的一种实现方式，UE可以通过RAN，向AMF发送NAS消息(NAS message)，该NAS消息中携带上述第一请求。As an implementation of this step 701, the UE may send a NAS message (NAS message) to the AMF through the RAN, and the NAS message carries the above-mentioned first request.

步骤702，AMF向SMF发送第二请求。相应的，SMF可以接收到该第二请求。Step 702: AMF sends a second request to SMF. Correspondingly, the SMF can receive the second request.

该第二请求携带上述PDU会话的标识以及用户组标识。The second request carries the identifier of the PDU session and the user group identifier.

步骤703，SMF根据用户组标识，确定同步调度指示信息。Step 703: The SMF determines synchronization scheduling indication information according to the user group identifier.

其中，SMF根据用户组标识确定同步调度指示信息的实现方法可以参考图4对应的实施例的步骤402的相关描述，这里不再赘述。Wherein, the method for implementing the SMF to determine the synchronization scheduling indication information according to the user group identifier may refer to the related description of step 402 in the embodiment corresponding to FIG. 4, which will not be repeated here.

需要说明的是，如果同一个用户组内不同的UE的PDU会话对应的SMF不同，那么不同的SMF接收到不同UE发送的用户组标识之后，不同的SMF根据同一个用户组标识确定的同步调度指示信息是相同的。可以理解为，不同的SMF上配置相同的用户组标识与同步调度标识之间的对应关系，因此，不同的SMF就能根据相同的用户组标识确定相同的同步调度指示信息。It should be noted that if the SMFs corresponding to the PDU sessions of different UEs in the same user group are different, then after different SMFs receive the user group identifiers sent by different UEs, different SMFs determine the synchronization scheduling based on the same user group identifier The instructions are the same. It can be understood that the corresponding relationship between the same user group identifier and the synchronization scheduling identifier is configured on different SMFs. Therefore, different SMFs can determine the same synchronization scheduling indication information according to the same user group identifier.

可选的，在该过程中，SMF还可以与PCF进一步更新会话管理相关策略。Optionally, in this process, the SMF and the PCF may further update the relevant policies for session management.

步骤704，SMF向AMF发送第二响应。相应的，AMF可以接收到该第二响应。Step 704: The SMF sends a second response to the AMF. Correspondingly, the AMF can receive the second response.

该第二响应携带上述同步调度指示信息，以及还携带PDU会话的标识。例如，可以在第二响应携带N2会话管理容器(N2 SM container)，N2 SM container中携带上述同步调度指示信息和PDU会话的标识。该第二响应还可以携带N1会话管理容器(N1 SM container)，N1 SM container中携带PDU会话的标识以及第一响应。The second response carries the aforementioned synchronization scheduling indication information and also carries the identifier of the PDU session. For example, the second response may carry an N2 session management container (N2 SM container), and the N2 SM container may carry the foregoing synchronization scheduling indication information and the identifier of the PDU session. The second response may also carry the N1 session management container (N1 SM container), and the N1 SM container carries the identifier of the PDU session and the first response.

步骤705，AMF向RAN发送第三请求。相应的，RAN可以接收到该第三请求。Step 705: AMF sends a third request to the RAN. Correspondingly, the RAN can receive the third request.

该第三请求包含N2 SM container和N1 SM container，其中，N2 SM container包含同步调度指示信息和PDU会话的标识。The third request includes the N2 SM container and the N1 SM container, where the N2 SM container includes the synchronization scheduling indication information and the identifier of the PDU session.

步骤706，RAN根据同步调度指示信息和PDU会话的标识，为UE分配空口调度资源。Step 706: The RAN allocates air interface scheduling resources for the UE according to the synchronization scheduling indication information and the identifier of the PDU session.

其中，PDU会话的标识用于指示需要分配空口调度资源的PDU会话。Among them, the identifier of the PDU session is used to indicate the PDU session for which air interface scheduling resources need to be allocated.

RAN根据同步调度指示信息和PDU会话的标识，为UE的PDU会话分配空口调度资源的实现方法，可以是：The RAN allocates air interface scheduling resources for the UE's PDU session according to the synchronization scheduling indication information and the PDU session identifier, which can be:

方法一，RAN根据同步调度指示信息和PDU会话的标识，从空闲资源中为UE在分配空口调度资源。Method 1: The RAN allocates air interface scheduling resources for the UE from idle resources according to the synchronization scheduling indication information and the PDU session identifier.

比如，RAN根据接收到的同步调度指示信息，确定该UE是用户组内的第一个请求分配空口调度资源的UE，或者，RAN确定之前未收到过与所述用户组内的UE关联的同步调度指示信息，则RAN可以按照正常流程分配空口调度资源，比如按照现有技术中的资源分配方式，从空闲资源中为该UE的PDU会话分配空口调度资源，即RAN根据自身的资源分配情况确定该UE的上行数据调度的时间单元，并给UE发送资源调度指派(Grant)，通知UE在某个时间单元发送该PDU会话的上行数据。同时RAN本地保存该同步调度指示信息与该调度资源的对应关系。后续UE将上行数据按照RAN分配的空口调度资源发送给RAN。在为UE的PDU会话分配空口调度资源之后，RAN还可以为用户组内的其他UE的PDU会话的分配预留资源，该预留资源与已经分配给该UE的PDU会话的空口调度资源处于相同或相邻的时间单元。即，该预留资源适用于用户组内的其他UE的PDU会话。例如，UE1和UE2属于同一个用户组，且UE1需要与UE2同步空口调度资源。参考图5A和图5B，为分配空口调度资源的示意图。图5A中，在空口侧为UE1和UE2分配的调度资源处于相同的时间单元。图5B中，为UE1和UE2分配的调度资源处于相邻的时间单元。For example, according to the received synchronization scheduling indication information, the RAN determines that the UE is the first UE in the user group to request the allocation of air interface scheduling resources, or the RAN determines that it has not received any information associated with the UE in the user group before. Synchronous scheduling indication information, the RAN can allocate air interface scheduling resources according to the normal process, for example, according to the resource allocation method in the prior art, allocate air interface scheduling resources for the PDU session of the UE from idle resources, that is, the RAN can allocate air interface scheduling resources according to its own resource allocation. Determine the time unit for uplink data scheduling of the UE, and send a resource scheduling assignment (Grant) to the UE to notify the UE to send the uplink data of the PDU session in a certain time unit. At the same time, the RAN locally stores the corresponding relationship between the synchronization scheduling indication information and the scheduling resource. Subsequently, the UE sends the uplink data to the RAN according to the air interface scheduling resources allocated by the RAN. After allocating air interface scheduling resources for the PDU session of the UE, the RAN can also reserve resources for the allocation of PDU sessions of other UEs in the user group. The reserved resources are the same as the air interface scheduling resources of the PDU sessions that have been allocated to the UE. Or adjacent time units. That is, the reserved resources are applicable to PDU sessions of other UEs in the user group. For example, UE1 and UE2 belong to the same user group, and UE1 needs to synchronize air interface scheduling resources with UE2. Referring to FIG. 5A and FIG. 5B, it is a schematic diagram of allocating air interface scheduling resources. In FIG. 5A, the scheduling resources allocated to UE1 and UE2 on the air interface side are in the same time unit. In FIG. 5B, the scheduling resources allocated to UE1 and UE2 are in adjacent time units.

再比如，RAN根据接收到的同步调度指示信息确定该UE不是用户组内的第一个请求分配空口调度资源的UE，或者，RAN确定之前收到过与所述用户组内的UE关联的同步调度指示信息，则RAN可以从该预留资源中，为该UE的PDU会话分配空口调度资源。For another example, the RAN determines that the UE is not the first UE in the user group to request the allocation of air interface scheduling resources according to the received synchronization scheduling indication information, or the RAN determines that it has previously received synchronization associated with UEs in the user group. According to the scheduling indication information, the RAN can allocate air interface scheduling resources for the PDU session of the UE from the reserved resources.

方法二，RAN根据同步调度指示信息和PDU会话的标识，从用户组对应的空口资源中，为该UE分配空口调度资源。Method 2: The RAN allocates air interface scheduling resources for the UE from the air interface resources corresponding to the user group according to the synchronization scheduling indication information and the identifier of the PDU session.

比如，RAN根据接收到的同步调度指示信息，确定该UE是用户组内的第一个请求分配空口调度资源的UE，或者，RAN确定之前未收到过与所述用户组内的UE关联的同步调度指示信息，则RAN可以从该用户组对应的空口资源中为该UE的PDU会话分配空口调度资源，即RAN根据自身的资源分配情况确定该UE的上行数据调度的时间单元，并给UE发送资源调度指派(Grant)，通知UE在某个时间单元发送该上行数据。后续UE将上行数据按照RAN分配的资源发送给RAN。在为UE的PDU会话分配空口调度资源之后，RAN还可以为用户组内的其他UE的PDU会话分配预留资源，该预留资源是上述空口资源中的资源，且与已经分配给该UE的PDU会话的空口调度资源处于相同或相邻的时间单元。即，该预留资源适用于用户组内的其他UE的PDU会话。例如，UE1和UE2属于同一个用户组，且UE1需要与UE2同步空口调度资源。参考图5A和图5B，为分配空口调度资源的示意图。图5A中，在空口侧为UE1和UE2分配的调度资源处于相同的时间单元。图5B中，为UE1和UE2分配的调度资源处于相邻的时间单元。For example, according to the received synchronization scheduling indication information, the RAN determines that the UE is the first UE in the user group to request the allocation of air interface scheduling resources, or the RAN determines that it has not received any information associated with the UE in the user group before. Synchronous scheduling indication information, the RAN can allocate air interface scheduling resources for the PDU session of the UE from the air interface resources corresponding to the user group, that is, the RAN determines the time unit for uplink data scheduling of the UE according to its own resource allocation, and gives it to the UE. Send a resource scheduling assignment (Grant) to notify the UE to send the uplink data in a certain time unit. Subsequently, the UE sends the uplink data to the RAN according to the resources allocated by the RAN. After allocating air interface scheduling resources for the PDU session of the UE, the RAN can also allocate reserved resources for the PDU sessions of other UEs in the user group. The reserved resources are the above-mentioned air interface resources and are different from those already allocated to the UE. The air interface scheduling resources of the PDU session are in the same or adjacent time unit. That is, the reserved resources are applicable to PDU sessions of other UEs in the user group. For example, UE1 and UE2 belong to the same user group, and UE1 needs to synchronize air interface scheduling resources with UE2. Referring to FIG. 5A and FIG. 5B, it is a schematic diagram of allocating air interface scheduling resources. In FIG. 5A, the scheduling resources allocated to UE1 and UE2 on the air interface side are in the same time unit. In FIG. 5B, the scheduling resources allocated to UE1 and UE2 are in adjacent time units.

需要说明的是，RAN确定该UE是用户组内的第一个请求分配空口调度资源的UE或者RAN确定之前收到过与所述用户组内的UE关联的同步调度指示信息，指的是，在某个时间范围内(比如，以演唱会场景为例，主唱、贝斯手、吉他手、鼓手等作为用户组内的UE具有空口调度同步需求，在一场演唱会的开始到结束的时间范围内等)RAN确定之前未收到过与所述用户组内的UE关联的同步调度指示信息。It should be noted that the RAN determines that the UE is the first UE in the user group to request the allocation of air interface scheduling resources or the RAN determines that it has previously received synchronization scheduling indication information associated with the UE in the user group, which refers to: In a certain time range (for example, taking a concert scene as an example, the UE in the user group as the lead singer, bassist, guitarist, drummer, etc., has air-interface scheduling synchronization requirements, and the time range from the beginning to the end of a concert (Internal etc.) The RAN determines that it has not received the synchronization scheduling indication information associated with the UE in the user group before.

需要注意的是，本申请实施例中，同一个用户组内不同的UE接入的是同一个RAN。这样即便是同一个用户组内不同的UE的PDU会话对应的SMF不同，但在步骤703中，不同的SMF根据相同的用户组标识确定相同的同步调度指示信息，因此RAN可以为同一个用户组内不同的UE分配同步的空口调度资源。It should be noted that in this embodiment of the application, different UEs in the same user group access the same RAN. In this way, even if the SMFs corresponding to the PDU sessions of different UEs in the same user group are different, in step 703, different SMFs determine the same synchronization scheduling indication information according to the same user group identifier, so the RAN can be the same user group Different UEs in the internal allocation of synchronized air interface scheduling resources.

步骤707，RAN向UE发送空口调度资源。相应的，UE可以接收到该空口调度资源。Step 707: The RAN sends air interface scheduling resources to the UE. Correspondingly, the UE can receive the air interface scheduling resource.

该空口调度资源即为RAN为UE分配的空口侧的用于发送上行数据的调度资源。UE可以根据RAN发送的空口调度资源进行本地配置，后续UE将上行数据按照RAN分配的空口调度资源发送给RAN。The air interface scheduling resource is the scheduling resource on the air interface side allocated by the RAN to the UE for sending uplink data. The UE can perform local configuration according to the air interface scheduling resources sent by the RAN, and subsequently the UE sends uplink data to the RAN according to the air interface scheduling resources allocated by the RAN.

例如，UE1和UE2属于同一个用户组，RAN为UE1和UE2分配空口调度资源的示意图可参考图5A和图5B。后续当UE1和UE2发送上行数据时，RAN对UE1和UE2分别发送的上行数据的调度示意图可参考图6，如果RAN在分配空口调度资源时，将UE1和UE2的上行数据放在同一个时间单元或相邻时间中进行调度，则可以尽量地保证UE1和UE2的上行数据同时传输到网络侧，这样网络进行混音处理的时候，可以尽可能地同时收到UE1和UE2的上行数据，从而有助于保证混音处理的效果和质量。上述方案，UE在第一请求中携带用户组标识，网络侧(SMF)可以基于用户组标识确定RAN侧的同步调度指示信息，RAN可以根据该同步调度指示信息为用户组内的UE分配处于相同或相邻时间单元的空口调度资源，从而网络侧可以在尽可能短的时延内接收到用户组内的不同UE发送的数据，有助于提升数据处理的质量。For example, UE1 and UE2 belong to the same user group, and the schematic diagram of RAN allocating air interface scheduling resources to UE1 and UE2 can refer to FIG. 5A and FIG. 5B. Subsequent when UE1 and UE2 send uplink data, the RAN scheduling diagram of the uplink data sent by UE1 and UE2 respectively can refer to Figure 6. If the RAN allocates air interface scheduling resources, the uplink data of UE1 and UE2 are placed in the same time unit. Or scheduling in adjacent time, you can try to ensure that the uplink data of UE1 and UE2 are transmitted to the network side at the same time, so that when the network is performing mixing processing, it can receive the uplink data of UE1 and UE2 as much as possible. Helps ensure the effect and quality of the mixing process. In the above solution, the UE carries the user group identifier in the first request, and the network side (SMF) can determine the synchronization scheduling indication information on the RAN side based on the user group identifier, and the RAN can assign the UEs in the user group the same according to the synchronization scheduling indication information. Or air interface scheduling resources of adjacent time units, so that the network side can receive data sent by different UEs in the user group within the shortest possible time delay, which helps to improve the quality of data processing.

如图8所示，为本申请实施例提供的又一种资源分配方法流程示意图。该方案中，在UE已经建立了会话之后，AF向网络发送请求，请求中携带用户组标识，如此，网络可以基于用户组标识确定同步调度指示信息，然后将同步调度指示信息发送给RAN。如此，RAN可以为该UE进行特殊的资源调度，即对处于同一用户组的UE进行资源的同步调度。As shown in FIG. 8, it is a schematic flowchart of another resource allocation method provided by an embodiment of this application. In this solution, after the UE has established a session, the AF sends a request to the network, and the request carries the user group identifier. In this way, the network can determine the synchronization scheduling indication information based on the user group identifier, and then send the synchronization scheduling indication information to the RAN. In this way, the RAN can perform special resource scheduling for the UE, that is, perform resource synchronization scheduling for UEs in the same user group.

步骤801，AF向PCF发送策略更新请求(Npcf_PolicyAuthorization update request)。相应的，PCF可以接收到该策略更新请求。Step 801: The AF sends a policy update request (Npcf_Policy Authorization update request) to the PCF. Correspondingly, the PCF can receive the policy update request.

比如，AF可以通过NEF向PCF发送上述策略更新请求。For example, the AF can send the aforementioned policy update request to the PCF through the NEF.

该策略更新请求中携带用户组标识和该用户组标识对应的UE列表(UE list)。The policy update request carries a user group identifier and a UE list (UE list) corresponding to the user group identifier.

该用户组内的任意一个UE需要与该用户组内的其他UE同步的空口调度资源。Any UE in the user group needs air interface scheduling resources synchronized with other UEs in the user group.

UE列表包含一个或多个UE的标识，UE列表中的UE的标识属于上述用户组。The UE list contains the identities of one or more UEs, and the identities of the UEs in the UE list belong to the aforementioned user group.

步骤802，PCF触发PDU会话相关策略更新流程(PCF initiated SMF Policy Association Modification)，在该过程中PCF触发SMF针对UE列表指示的UE的PDU会话更新，PCF将用户组标识和UE列表发送给SMF。In step 802, the PCF triggers a PDU session-related policy update process (PCF initiated SMF Policy Association Modification). In this process, the PCF triggers the SMF to update the PDU session of the UE indicated by the UE list, and the PCF sends the user group identifier and the UE list to the SMF.

步骤803，SMF根据用户组标识确定同步调度指示信息，以及确定UE列表指示的各个UE分别对应的PDU会话的标识。In step 803, the SMF determines the synchronization scheduling indication information according to the user group identifier, and determines the identifier of the PDU session corresponding to each UE indicated by the UE list.

步骤804，SMF向AMF发送同步调度指示信息和PDU会话的标识。In step 804, the SMF sends the synchronization scheduling indication information and the PDU session identifier to the AMF.

比如，SMF可以通过Namf_Communication_N1N2MessageTransfer request，向AMF发送同步调度指示信息和PDU会话的标识。For example, SMF can send synchronization scheduling indication information and PDU session identifier to AMF through Namf_Communication_N1N2MessageTransfer request.

步骤805，AMF向RAN发送N2会话请求(N2 session request)。相应的，RAN可以接收到该N2会话请求。Step 805: The AMF sends an N2 session request (N2 session request) to the RAN. Correspondingly, the RAN can receive the N2 session request.

该N2会话请求包含N2 SM container和N1 SM container，其中，N2 SM container包含同步调度指示信息和PDU会话的标识，N1 SM container中携带PDU会话的标识以及PDU会话修改应答消息(PDU Session Modification ack)。The N2 session request includes N2 SM container and N1 SM container, where N2 SM container includes synchronization scheduling indication information and PDU session identifier, and N1 SM container carries PDU session identifier and PDU session modification acknowledgement message (PDU Session Modification ack) .

步骤806，RAN根据同步调度指示信息和PDU会话的标识，为UE分配空口调度资源。Step 806: The RAN allocates air interface scheduling resources for the UE according to the synchronization scheduling indication information and the identifier of the PDU session.

RAN根据同步调度指示信息和PDU会话的标识，为UE的PDU会话分配空口调度资源的实现方法，可以参考图7对应的实施例的相关描述，这里不再赘述。For the implementation method for the RAN to allocate air interface scheduling resources for the PDU session of the UE according to the synchronization scheduling indication information and the identifier of the PDU session, reference may be made to the related description of the embodiment corresponding to FIG.

需要注意的是，本申请实施例中，同一个用户组内不同的UE接入的是同一个RAN。这样即便是同一个用户组内不同的UE的PDU会话对应的SMF不同，但在步骤803中，不同的SMF根据相同的用户组标识确定相同的同步调度指示信息，因此RAN可以为同一个用户组内不同的UE分配同步的空口调度资源。It should be noted that in this embodiment of the application, different UEs in the same user group access the same RAN. In this way, even if the SMFs corresponding to the PDU sessions of different UEs in the same user group are different, in step 803, different SMFs determine the same synchronization scheduling indication information according to the same user group identifier, so the RAN can be the same user group Different UEs in the internal allocation of synchronized air interface scheduling resources.

步骤807，RAN向UE发送空口调度资源。相应的，UE可以接收到该空口调度资源。Step 807: The RAN sends air interface scheduling resources to the UE. Correspondingly, the UE can receive the air interface scheduling resource.

该步骤807中，RAN还可以向UE发送上述N1 SM container。UE在接收到N1 SM container之后，可以获取到其中的PDU会话修改应答消息和PDU会话的标识。In step 807, the RAN may also send the aforementioned N1 SM container to the UE. After receiving the N1 SM container, the UE can obtain the PDU session modification response message and the PDU session identifier therein.

步骤808，RAN向AMF发送N2会话响应，相应的，AMF可以接收到该N2会话响应。In step 808, the RAN sends an N2 session response to the AMF, and accordingly, the AMF can receive the N2 session response.

该步骤808为可选。This step 808 is optional.

上述方案，AF在策略更新请求中携带用户组标识，网络侧(SMF)可以基于用户组标识确定RAN侧的同步调度指示信息，RAN可以根据该同步调度指示信息为用户组内的UE分配处于相同或相邻时间单元的空口调度资源，从而网络侧可以在尽可能短的时延内接收到用户组内的不同UE发送的数据，有助于提升数据处理的质量。In the above solution, the AF carries the user group identifier in the policy update request, and the network side (SMF) can determine the synchronization scheduling indication information on the RAN side based on the user group identifier, and the RAN can assign the UEs in the user group to be in the same position according to the synchronization scheduling indication information. Or air interface scheduling resources of adjacent time units, so that the network side can receive data sent by different UEs in the user group within the shortest possible time delay, which helps to improve the quality of data processing.
