技术领域technical field
本申请涉及无线通信领域，尤其涉及通信方法、装置及***。The present application relates to the field of wireless communication, in particular to a communication method, device and system.
背景技术Background technique
在通信***中，终端可以周期性地向接入网设备发送数据包，也可以周期性地接收来自接入网设备的数据包。以终端周期性地向接入网设备发送数据包为例，一个周期内，终端可以向接入网设备发送多个数据包，每个数据包的大小不同。有的数据包较大，发送时需要的带宽也较大，有的数据包较小，发送时需要的带宽也较小。例如，在虚拟现实(virtual reality，VR)视频通信中，终端可以周期性地发送I帧和P帧。如图1所示，终端以I、P、P、P、I、P、P、P的模式周期性发送I帧和P帧。其中，相邻两帧(I帧与I帧，I帧与P帧或P帧与P帧)之间的时间间隔是固定的。I帧通常传输的数据包较大，占用的带宽也较大，具有突发高带宽特性。以I帧包括20毫秒(ms)为例，I帧要传输80M的数据。相对于I帧，P帧传输的数据包较小，占用的带宽也较小，数据传输相对比较平缓。以P帧包括10ms为例，P帧要传输10M的数据。In the communication system, the terminal may periodically send data packets to the access network device, and may also periodically receive data packets from the access network device. Taking the terminal periodically sending data packets to the access network device as an example, within one cycle, the terminal may send multiple data packets to the access network device, and each data packet has a different size. Some data packets are larger and require a larger bandwidth for sending, while some data packets are smaller and require a smaller bandwidth for sending. For example, in virtual reality (virtual reality, VR) video communication, the terminal can periodically send I frames and P frames. As shown in FIG. 1 , the terminal periodically sends I frames and P frames in the mode of I, P, P, P, I, P, P, P. Wherein, the time interval between two adjacent frames (I frame and I frame, I frame and P frame or P frame and P frame) is fixed. The I frame usually transmits a large data packet and occupies a large bandwidth, which has the characteristic of bursting high bandwidth. Taking an I frame including 20 milliseconds (ms) as an example, the I frame needs to transmit 80M data. Compared with the I frame, the data packet transmitted by the P frame is smaller, the occupied bandwidth is also smaller, and the data transmission is relatively smooth. Taking the P frame including 10ms as an example, the P frame needs to transmit 10M data.
在终端发送较大数据包的情况下，会占用较大的带宽，所以会对无线通信形成较大挑战。尤其是在多个终端同时发送较大数据包的情况下，会导致空口拥塞，数据丢包率和数据传输时延较大，影响用户体验。When the terminal sends a large data packet, it will occupy a large bandwidth, so it will pose a great challenge to wireless communication. Especially when multiple terminals send large data packets at the same time, it will lead to air interface congestion, large data packet loss rate and data transmission delay, which will affect user experience.

本申请实施例中，第一特征信息可以用于指示第一业务流的带宽和周期。或者说，第一特征信息可以指示第一业务流的数据包的发送规律，例如，第一特征信息可以包括如下信息中的至少一项：相邻两个突发(或帧)的时间间隔、每个突发(或帧)所占用的带宽大小、一个周期内所包括的突发(或帧)的发送模式等。或者说，第一特征信息至少可以恢复出第一业务流的较大突发的发送规律，例如，第一特征信息可以包括如下信息中的至少一项：相邻两个较大突发(或帧)帧的时间间隔、较大突发(或帧)所占用的带宽大小。在本申请实施例中，帧和突发可以互相替换。一个突发(或帧)中可以发送第一业务流的至少一个数据包。In this embodiment of the present application, the first feature information may be used to indicate the bandwidth and period of the first service flow. In other words, the first characteristic information may indicate the sending regularity of the data packets of the first service flow. For example, the first characteristic information may include at least one of the following information: the time interval between two adjacent bursts (or frames), The size of the bandwidth occupied by each burst (or frame), the transmission mode of the burst (or frame) included in one cycle, and the like. In other words, the first characteristic information can at least recover the sending rule of the larger burst of the first service flow, for example, the first characteristic information can include at least one of the following information: two adjacent larger bursts (or Frame) The time interval of the frame, the bandwidth size occupied by the larger burst (or frame). In this embodiment of the application, frame and burst can be replaced with each other. At least one data packet of the first service flow can be sent in one burst (or frame).
作为一种示例，若第一业务流的数据包的发送规律如图1所示，则第一特征信息可以指示：I帧和P帧的发送模式(在该示例中，发送模式为IPPP，即发送1个I帧，再发送3个P帧，再发送1个I帧，再发送3个P帧，以此类推，其中I帧是一种突发、P帧是另外一种突发)、该发送模式对应的周期(即一个I帧与下一个I帧间的时间间隔)、一个周期内相邻两个P帧的时间间隔、一个周期内相邻I帧和P帧的时间间隔、I帧传输的数据包的大小(即I帧所占用的带宽大小)和P帧传输的数据包的大小(即P帧所占用的带宽大小)。在具体应用中，相邻两帧间的时间间隔可以相同。例如，上述示例中，I帧与它相邻的P帧的时间间隔、相邻的两个P帧间的时间间隔、前一周期的最后一个P帧与相邻的后一周期的I帧间的时间间隔均相同，在这种情况下，第一特征信息可以简化为：I帧和P帧的发送模式(如IPPP)、帧间隔(或频率)、I帧所占用的带宽大小、P帧所占用的带宽大小。As an example, if the sending rule of the data packets of the first service flow is as shown in Figure 1, the first characteristic information may indicate: the sending mode of the I frame and the P frame (in this example, the sending mode is IPPP, that is, Send 1 I frame, then send 3 P frames, then send 1 I frame, then send 3 P frames, and so on, where I frame is a burst, P frame is another burst), The cycle corresponding to the transmission mode (that is, the time interval between one I frame and the next I frame), the time interval between two adjacent P frames in one cycle, the time interval between adjacent I frames and P frames in one cycle, and the I The size of the data packet transmitted by the frame (that is, the size of the bandwidth occupied by the I frame) and the size of the data packet transmitted by the P frame (that is, the size of the bandwidth occupied by the P frame). In a specific application, the time interval between two adjacent frames may be the same. For example, in the above example, the time interval between an I frame and its adjacent P frame, the time interval between two adjacent P frames, the time interval between the last P frame of the previous cycle and the adjacent I frame of the next cycle In this case, the first characteristic information can be simplified as: the transmission mode (such as IPPP) of the I frame and the P frame, the frame interval (or frequency), the bandwidth size occupied by the I frame, the size of the P frame The amount of bandwidth used.
作为另一种示例，为了降低第一网络侧设备的复杂度，可以简化第一特征信息。例如，第一特征信息可以不指示较小帧(例如P帧)的信息，而是指示较大帧(例如I帧)的信息，以便第一网络侧设备根据第一特征信息恢复出较大帧的发送规律。例如，第一特征信息可以包括：I帧的发送周期(或频率)、以及I帧所占用的带宽大小。第一特征信息还可以包括I帧和/或P帧的发送时长。I帧的发送时长还可以称为大数据包的发送时长，即I帧的持续时间。P帧的发送时长还可以称为小数据包的发送时长，即P帧的持续时间。I帧的发送时长和P帧的发送时长可以相同也可以不同。As another example, in order to reduce the complexity of the first network side device, the first characteristic information may be simplified. For example, the first characteristic information may not indicate information of a smaller frame (such as a P frame), but may indicate information of a larger frame (such as an I frame), so that the first network side device can restore the larger frame according to the first characteristic information sending rules. For example, the first feature information may include: the sending period (or frequency) of the I frame, and the bandwidth occupied by the I frame. The first feature information may also include the sending duration of the I frame and/or the P frame. The sending duration of the I frame may also be referred to as the sending duration of the large data packet, that is, the duration of the I frame. The sending duration of the P frame may also be referred to as the sending duration of the small data packet, that is, the duration of the P frame. The sending duration of the I frame and the sending duration of the P frame may be the same or different.
可选的，若第一业务流的数据包未开始发送，则第一特征信息还可以用于指示第一业务流的数据包的预计起始发送时间。若第一业务流的数据包已经开始发送，则第一特征信息还可以用于指示第一业务流的至少一个数据包的发送时间、或至少一个帧 的发送时间、或至少一个周期的开始时间。例如，第一特征信息还可以指示第一业务流的第一个数据包的发送时间；或者，第一特征信息还可以指示一个周期的开始时间(如，一个周期从I帧开始，则第一特征信息还可以指示I帧的发送时间，或I帧的第一个数据包的发送时间)；或者，第一特征信息还可以指示一个周期中的任一个帧(或该帧的至少一个数据包)的发送时间。若第一特征信息指示的是至少一个帧(或该帧的至少一个数据包)的发送时间，第一特征信息还可以指示该帧(或该数据包对应的帧)对应一个周期中的哪个帧，以便第一网络侧设备确定第一业务流的发送时间(即，第一业务流在时间轴上的位置)。Optionally, if the data packets of the first service flow have not started to be sent, the first characteristic information may also be used to indicate the expected start time of sending the data packets of the first service flow. If the data packets of the first service flow have started to be sent, the first feature information may also be used to indicate the sending time of at least one data packet of the first service flow, or the sending time of at least one frame, or the start time of at least one cycle . For example, the first feature information can also indicate the sending time of the first data packet of the first service flow; or, the first feature information can also indicate the start time of a cycle (such as, a cycle starts from an I frame, then the first The feature information can also indicate the sending time of the I frame, or the sending time of the first data packet of the I frame); or, the first feature information can also indicate any frame (or at least one data packet of the frame) in a cycle ) of the sending time. If the first characteristic information indicates the sending time of at least one frame (or at least one data packet of the frame), the first characteristic information may also indicate which frame in a period the frame (or the frame corresponding to the data packet) corresponds to , so that the first network side device determines the sending time of the first service flow (that is, the position of the first service flow on the time axis).
可以理解的，第一网络侧设备获取第一特征信息后，可以根据第一特征信息恢复出第一业务流的数据包的发送规律。或者说，第一网络侧设备获取第一特征信息后，至少可以根据第一特征信息恢复出第一业务流中、较大帧的发送规律。如此，第一网络侧设备可以结合第一小区中、除第一业务流之外的其他业务流的特征信息，确定第一业务流的至少一个数据包的发送时间，使得第一小区中的业务流的数据包可以错峰发送，从而减少空口拥塞的情况出现。It can be understood that after the first network side device acquires the first feature information, it can recover the sending rule of the data packets of the first service flow according to the first feature information. In other words, after acquiring the first feature information, the first network side device can at least recover the sending rule of the larger frame in the first service flow according to the first feature information. In this way, the first network side device can determine the sending time of at least one data packet of the first service flow in combination with the characteristic information of other service flows in the first cell except the first service flow, so that the service in the first cell Stream data packets can be sent at staggered peaks, thereby reducing air interface congestion.
S702：第一网络侧设备根据第一特征信息和其他业务流的特征信息确定第一调度信息。S702: The first network side device determines first scheduling information according to the first feature information and feature information of other service flows.
其中，其他业务流为第一小区中、除第一业务流之外的业务流。也就是说，第一网络侧设备获取到第一小区的信息后，可以根据第一小区的信息获取通过第一小区进行传输的其他业务流的特征信息，再根据第一特征信息和其他业务流的特征信息确定第一调度信息。其中，其他业务流包括第二业务流。第二业务流与第一业务流不同。第二业务流可以是第一终端的业务流，也可以是除第一终端之外，接入第一小区中的其他终端的业务流。第二业务流的数据包已经开始发送或者还未开始发送。Wherein, other service flows are service flows in the first cell except the first service flow. That is to say, after the first network side device obtains the information of the first cell, it can obtain the feature information of other service flows transmitted through the first cell according to the information of the first cell, and then according to the first feature information and other service flows The characteristic information determines the first scheduling information. Wherein, other service flows include the second service flow. The second service flow is different from the first service flow. The second service flow may be a service flow of the first terminal, or may be a service flow of other terminals accessing the first cell except the first terminal. The data packets of the second service flow have started to be sent or have not yet started to be sent.
其中，第二业务流的第二特征信息可以用于指示第二业务流的带宽、周期和第二业务流的至少一个数据包的发送时间。第二特征信息可以使得第一网络侧设备恢复出第二业务流的数据包的发送规律。或者说，第二特征信息至少可以使得第一网络侧设备恢复出第二业务流中、较大帧的发送规律。以第二业务流的数据包的发送规律如图1所示为例，第二特征信息可以指示：I帧和P帧的发送模式、该发送模式对应的周期、一个周期内相邻两个P帧的时间间隔、一个周期内相邻I帧和P帧的时间间隔、第二业务流的任一周期的开始时间、I帧所占用的带宽大小和P帧所占用的带宽大小。或者，第二特征信息可以指示：I帧的发送周期(或频率)、第二业务流的任一I帧的发送时间、I帧所占用的带宽大小。Wherein, the second feature information of the second service flow may be used to indicate the bandwidth, period, and sending time of at least one data packet of the second service flow. The second feature information may enable the first network side device to recover the sending rule of the data packets of the second service flow. In other words, the second feature information can at least enable the first network side device to recover the sending rule of the larger frame in the second service flow. Taking the sending rule of the data packet of the second service flow as shown in Figure 1 as an example, the second feature information can indicate: the sending mode of I frame and P frame, the period corresponding to the sending mode, and two adjacent P frames in one period. The time interval of frames, the time interval between adjacent I frames and P frames in one period, the start time of any period of the second service flow, the bandwidth occupied by I frames and the bandwidth occupied by P frames. Alternatively, the second feature information may indicate: the sending period (or frequency) of the I frame, the sending time of any I frame of the second service flow, and the bandwidth occupied by the I frame.
一种可能的实现方式，第二特征信息是第一网络侧设备在S702之前获取的。第一网络侧设备获取第二特征信息的过程与第一网络侧设备获取第一特征信息的过程类似，可以参考下述第一网络侧设备获取第一特征信息的介绍，不做赘述。In a possible implementation manner, the second feature information is acquired by the first network side device before S702. The process for the first network-side device to obtain the second characteristic information is similar to the process for the first network-side device to obtain the first characteristic information. You can refer to the following introduction of the first network-side device to obtain the first characteristic information, and details will not be repeated.
本申请实施例中，第一调度信息用于确定第一业务流的至少一个数据包的发送时间。例如，第一调度信息可以包括第一业务流的至少一个数据包的发送时间，或者，第一调度信息可以指示至少一个时间区间，第一业务流的至少一个数据包的发送时间可以位于该时间区间内。其中，至少一个数据包可以是第一业务流的第一帧的至少一个数据包(也就是说，第一调度信息用于确定第一业务流的第一帧的开始发送时间)， 或者，至少一个数据包也可以是第一业务流的至少一个周期的第一帧的至少一个数据包(也就是说，第一调度信息用于确定第一业务流的至少一个周期的开始时间)。In this embodiment of the present application, the first scheduling information is used to determine the sending time of at least one data packet of the first service flow. For example, the first scheduling information may include the sending time of at least one data packet of the first service flow, or the first scheduling information may indicate at least one time interval, and the sending time of at least one data packet of the first service flow may be at this time within the range. Wherein, the at least one data packet may be at least one data packet of the first frame of the first service flow (that is, the first scheduling information is used to determine the start sending time of the first frame of the first service flow), or, at least A data packet may also be at least one data packet of the first frame of at least one period of the first service flow (that is, the first scheduling information is used to determine the start time of at least one period of the first service flow).
可选的，第一调度信息还可以包括编码率，和/或，调制阶数。若第一业务流具有高可靠性需求，则第一网络侧设备可以确定一个较低的编码率或较低的调制阶数。Optionally, the first scheduling information may further include a coding rate and/or a modulation order. If the first service flow has a high reliability requirement, the first network side device may determine a lower coding rate or a lower modulation order.
可以理解的，若第一业务流的数据包未开始发送，则第一调度信息用于确定第一业务流的至少一个数据包的起始发送时间，或者，第一帧的开始发送时间，或者，至少一个周期的第一帧的开始发送时间。若第一业务流的数据包已经开始发送，则第一调度信息用于确定第一业务流的至少一个数据包的下一次发送时间，或者，至少一帧的下一次发送时间，其中，至少一帧可以是一个周期中包括第一帧在内的任意一帧。可以理解的，若第一业务流的数据包已经开始发送，则第一调度信息可以包括第一业务流的至少一个数据包发送时间的调整时间，例如，延迟10ms进行发送。It can be understood that if the data packets of the first service flow have not started to be sent, the first scheduling information is used to determine the start sending time of at least one data packet of the first service flow, or the start sending time of the first frame, or , the start sending time of the first frame of at least one cycle. If the data packets of the first service flow have started to be sent, the first scheduling information is used to determine the next sending time of at least one data packet of the first service flow, or the next sending time of at least one frame, wherein at least one A frame can be any frame including the first frame in a cycle. It can be understood that, if the data packets of the first service flow have started to be sent, the first scheduling information may include an adjustment time for sending at least one data packet of the first service flow, for example, the sending is delayed by 10 ms.
本申请实施例中，第一网络侧设备可以根据第一特征信息和其他业务流的特征信息确定第一调度信息，使得第一业务流的数据包可以在空口不拥塞的时刻发送，或者避免第一业务流的较大帧与其他业务流的较大帧同时发送导致空口拥塞。In this embodiment of the present application, the first network side device can determine the first scheduling information according to the first characteristic information and characteristic information of other service flows, so that the data packets of the first service flow can be sent when the air interface is not congested, or avoid the second scheduling information. Larger frames of one service flow and larger frames of other service flows are sent at the same time, resulting in air interface congestion.
一种可能的实现方式，在根据第二特征信息发送第二业务流的数据包，以及根据第一调度信息发送第一业务流的数据包的情况下，同一时刻下的第二业务流的数据包和第一业务流的数据包占用的带宽的总和的最大值小于或等于第一阈值。In a possible implementation manner, when the data packets of the second service flow are sent according to the second characteristic information, and the data packets of the first service flow are sent according to the first scheduling information, the data of the second service flow at the same time The maximum value of the sum of the bandwidth occupied by the packets and the data packets of the first service flow is less than or equal to the first threshold.
示例性的，以第一小区包括第一业务流和第二业务流，第一业务流的带宽和周期与第二业务流的带宽和周期相同，都如图8所示为例。图8中，第一业务流和第二业务流的发送模式都是先发一个I帧，再发两个P帧，再发一个I帧，再发两个P帧，以此类推。第一业务流和第二业务流的发送模式对应的周期都是T，第一业务流和第二业务流中相邻两帧的时间间隔都是t1。若第二业务流的第一帧的发送时间为t0，则第一网络侧设备可以确定第一业务流的第一个I帧的发送时间位于时间区间801中，或者第一网络侧设备可以确定第一业务流的下一个I帧的发送时间位于时间区间801中。时间区间801为[t0+△t+i*t1，t0+(i+1)*t1]，其中，i为大于或等于0的整数，△t是I帧的发送时长。图8中，I帧的发送时长与P帧的发送时长相同。可以看出，时间区间801包括多个区间，图8仅示出了一个区间。若第二业务流的P帧包占用的带宽较小，例如，第二业务流的P帧占用的带宽与第一业务流的I帧占用的带宽之和小于或等于第一阈值，则第一网络侧设备可以确定第一业务流的第一个I帧的发送时间位于时间区间802中，或者第一网络侧设备可以确定第一业务流的下一个I帧的发送时间位于时间区间802中。时间区间802为[t0+△t+i*T，t0+(i+1)*T]。可以看出，时间区间802包括多个区间，图8仅示出了一个区间。Exemplarily, the first cell includes a first service flow and a second service flow, and the bandwidth and period of the first service flow are the same as those of the second service flow, both of which are shown in FIG. 8 as an example. In Fig. 8, the sending modes of the first service flow and the second service flow are to send one I frame first, then two P frames, then one I frame, then two P frames, and so on. The period corresponding to the sending mode of the first service flow and the second service flow is both T, and the time interval between two adjacent frames in the first service flow and the second service flow is both t1. If the sending time of the first frame of the second service flow is t0, the first network side device may determine that the sending time of the first I frame of the first service flow is in the time interval 801, or the first network side device may determine that The sending time of the next I frame of the first service flow is located in the time interval 801 . The time interval 801 is [t0+Δt+i*t1, t0+(i+1)*t1], where i is an integer greater than or equal to 0, and Δt is the sending duration of an I frame. In FIG. 8 , the sending duration of the I frame is the same as that of the P frame. It can be seen that the time interval 801 includes multiple intervals, and FIG. 8 only shows one interval. If the bandwidth occupied by the P frames of the second service flow is small, for example, the sum of the bandwidth occupied by the P frames of the second service flow and the bandwidth occupied by the I frames of the first service flow is less than or equal to the first threshold, then the first The network side device may determine that the sending time of the first I frame of the first service flow is in the time interval 802 , or the first network side device may determine that the sending time of the next I frame of the first service flow is in the time interval 802 . The time interval 802 is [t0+Δt+i*T, t0+(i+1)*T]. It can be seen that the time interval 802 includes multiple intervals, and FIG. 8 only shows one interval.
应理解，上述示例中，为了便于理解，是以第一业务流的带宽和周期与第二业务流的带宽和周期相同为例进行描述的。在具体应用中，第一小区中的其他业务流的数量可以大于1个，并且第一业务流的带宽和周期可以与其他业务流的带宽和周期相同，也可以与其他业务流的带宽和周期不同，还可以与其他业务流中的部分业务流的带宽和周期相同，不予限制。It should be understood that, in the foregoing example, for ease of understanding, the bandwidth and period of the first service flow are the same as the bandwidth and period of the second service flow as an example for description. In a specific application, the number of other service flows in the first cell may be greater than one, and the bandwidth and period of the first service flow may be the same as those of other service flows, or may be the same as the bandwidth and period of other service flows. Different, the bandwidth and cycle of some service flows in other service flows can also be the same, without limitation.
可以理解的，若第一特征信息指示了第一业务流的数据包的预计起始发送时间，则第一网络侧设备在确定确定第一调度信息时可以考虑该预计起始发送时间。示例性 的，若该预计起始发送时间位于第一调度信息指示的时间区间中，例如位于时间区间801或时间区间802中，则第一业务流的第一个数据包的发送时间可以确定为该预计起始发送时间；若该预计起始发送时间没有位于第一调度信息指示的时间区间中，则第一业务流的第一个数据包的发送时间可以位于第一调度信息指示的时间区间中，与该预计起始发送时间相邻的时间区间。It can be understood that if the first feature information indicates the expected start time of sending the data packets of the first service flow, the first network side device may consider the expected start time of sending when determining the first scheduling information. Exemplarily, if the expected start sending time is in the time interval indicated by the first scheduling information, for example, in time interval 801 or time interval 802, the sending time of the first data packet of the first service flow may be determined as The estimated start sending time; if the expected start sending time is not located in the time interval indicated by the first scheduling information, the sending time of the first data packet of the first service flow may be located in the time interval indicated by the first scheduling information , the time interval adjacent to the expected start sending time.
示例性的，以第一网络侧设备确定第一业务流的至少一个数据包的发送时间可以位于时间区间1、时间区间2和时间区间3中为例，时间区间1、时间区间2和时间区间3可以如图9所示。若预计起始发送时间为时刻901，则第一业务流的第一个数据包的发送时间为时刻901。若预计起始发送时间为时刻902，则第一业务流的第一个数据包的发送时间可以位于时间区间1或时间区间2中。若预计起始发送时间为时刻903，则第一业务流的第一个数据包的发送时间可以位于时间区间2或时间区间3中。Exemplarily, taking the first network side device determining that the sending time of at least one data packet of the first service flow can be located in time interval 1, time interval 2 and time interval 3 as an example, time interval 1, time interval 2 and time interval 3 can be shown in Figure 9. If the estimated start sending time is time 901 , then the sending time of the first data packet of the first service flow is time 901 . If the expected start sending time is time 902, the sending time of the first data packet of the first service flow may be in time interval 1 or time interval 2. If the expected start sending time is time 903, the sending time of the first data packet of the first service flow may be in time interval 2 or time interval 3.
基于图7所示的方法，第一网络侧设备获取第一业务流的第一特征信息和第一小区信息后，可以结合第一小区中、除第一业务流之外的其他业务流的特征信息，确定第一业务流的至少一个数据包的发送时间，使得第一小区中的业务流的数据包可以错峰发送，从而减少空口拥塞的情况出现，降低数据丢包率和数据的传输时延，提高用户体验。Based on the method shown in Figure 7, after the first network side device obtains the first feature information and the first cell information of the first service flow, it can combine the characteristics of other service flows in the first cell except the first service flow Information, determine the sending time of at least one data packet of the first service flow, so that the data packets of the service flow in the first cell can be sent at staggered peaks, thereby reducing air interface congestion, reducing the data packet loss rate and data transmission time Delay, improve user experience.

When the cell accessed by the first terminal changes, the AMF may send information about the latest cell accessed by the first terminal to the SMF.

方式3：S701可以包括S1005和S1006。Manner 3: S701 may include S1005 and S1006.
S1005：UPF向SMF发送第一特征信息。相应的，SMF接收来自UPF的第一特征信息。S1005: The UPF sends the first feature information to the SMF. Correspondingly, the SMF receives the first feature information from the UPF.
其中，UPF可以为图2中的用户面网元202。UPF也可以为图5a或图5b中的UPF。Wherein, the UPF may be the user plane network element 202 in FIG. 2 . The UPF can also be the UPF in Figure 5a or Figure 5b.
可选的，在S1005之前，SMF向UPF发送第一指示信息。其中，第一指示信息用于指示检测第一业务流的第一特征信息，或者，第一指示信息用于指示检测应用的特征。第一业务流为该应用的业务流。Optionally, before S1005, the SMF sends the first indication information to the UPF. Wherein, the first indication information is used to indicate the first characteristic information of detecting the first service flow, or the first indication information is used to indicate the characteristic of the detection application. The first service flow is the service flow of the application.
作为一种示例，在第一指示信息指示检测第一业务流的第一特征信息的情况下，第一指示信息可以包括第一业务流的标识。示例性的，第一业务流的标识可以是第一业务流对应的五元组或三元组或第一业务流对应的应用服务器的地址。UPF接收到第一指示信息后，可以检测第一业务流的特征，得到第一特征信息，并将第一特征信息发送给SMF。As an example, in a case where the first indication information indicates to detect the first characteristic information of the first service flow, the first indication information may include the identifier of the first service flow. Exemplarily, the identifier of the first service flow may be a quintuple or triplet corresponding to the first service flow or an address of an application server corresponding to the first service flow. After receiving the first indication information, the UPF may detect the characteristics of the first service flow, obtain the first characteristic information, and send the first characteristic information to the SMF.
作为另一种示例，在第一指示信息用于指示检测应用的特征的情况下，第一指示信息可以包括一下至少一项：应用的标识(例如，应用的ID，或者应用的全限定域名(fully qualified domain name，FQDN))、第一业务流对应的应用服务器的地址(例如，应用服务器的互联网协议(internet protocol，IP)地址)、第一业务流对应的应用服务器的端口标识(例如，应用服务器的端口号)、或第一业务流对应的应用服务器的协议标识(例如，应用服务器的协议号)。UPF接收到第一指示信息后，可以检测应用的特征，得到应用的特征信息，并将应用的特征信息发送给SMF。其中，应用的特征信息可以包括该应用的业务流(包括第一业务流)的标识，以及每个业务流的标识所标识的业务流的特征信息(包括第一业务流的特征信息)。如此，SMF接收到应用的特征信息后，可以根据应用的特征信息确定第一业务流的第一特征信息。As another example, in the case where the first indication information is used to indicate the characteristics of the detected application, the first indication information may include at least one of the following: an identification of the application (for example, an ID of the application, or a fully qualified domain name of the application ( fully qualified domain name, FQDN)), the address of the application server corresponding to the first service flow (for example, the Internet protocol (internet protocol, IP) address of the application server), the port identifier of the application server corresponding to the first service flow (for example, port number of the application server), or the protocol identifier of the application server corresponding to the first service flow (for example, the protocol number of the application server). After receiving the first indication information, the UPF may detect the characteristics of the application, obtain the characteristic information of the application, and send the characteristic information of the application to the SMF. Wherein, the feature information of the application may include the identifier of the service flow (including the first service flow) of the application, and the feature information of the service flow (including the feature information of the first service flow) identified by the identifier of each service flow. In this way, after receiving the characteristic information of the application, the SMF may determine the first characteristic information of the first service flow according to the characteristic information of the application.
本申请实施例中，SMF可以向UPF指示检测哪些应用，也可以向UPF指示检测应用中的哪些业务流，还可以指示检测哪些特征，不予限制。示例性的，SMF可以向UPF指示检测第一业务流的每个帧的大小、帧的时间间隔、以及发送模式。In this embodiment of the present application, the SMF may indicate to the UPF which applications to detect, may also indicate to the UPF which service flows in the applications to detect, and may also indicate which features to detect, without limitation. Exemplarily, the SMF may instruct the UPF to detect the size of each frame of the first service flow, the time interval of the frames, and the sending mode.
可选的，第一指示信息还包括检测窗的配置信息。其中，检测窗的配置信息用于配置检测窗口，该检测窗口用于UPF检测第一特征信息。Optionally, the first indication information further includes configuration information of the detection window. Wherein, the configuration information of the detection window is used to configure the detection window, and the detection window is used for the UPF to detect the first feature information.
示例性的，该检测窗口可以是一个时间窗，例如，该检测窗口包括1ms。UPF接收到第一指示信息后，以1ms为窗口进行采样，以便确定在该1ms内第一业务流对应的数据包的数量、大小等信息。当1ms采用结束后，UPF继续下一个1ms的采用，计算下一个1ms内第一业务流对应的数据包的数量、大小等信息。这样，UPF在进行连续的1ms为窗口的采样后，可确定第一业务流的特征信息(如在何时发送数据帧(例如，I帧或P帧)，数据帧的大小等)。Exemplarily, the detection window may be a time window, for example, the detection window includes 1 ms. After receiving the first indication information, the UPF takes 1 ms as the window to perform sampling, so as to determine information such as the number and size of data packets corresponding to the first service flow within the 1 ms. When the 1ms adoption ends, the UPF continues to adopt the next 1ms, and calculates information such as the number and size of data packets corresponding to the first service flow within the next 1ms. In this way, the UPF can determine the characteristic information of the first service flow (such as when to send the data frame (for example, I frame or P frame), the size of the data frame, etc.) after performing continuous 1 ms window sampling.
可以理解的，SMF可以为不同的应用配置不同的检测窗口。另外，对于方法3，UPF在检测第一业务流的特征或应用的特征的时候，第一业务流的数据包已经开始发送。也就是说，SMF接收到第一特征信息的时候，第一业务流的数据包已经开始发送了。在这种情况下，UPF上报的第一特征信息中可以包括第一业务流的至少一个帧的开始发送时间，SMF确定的是第一业务流的至少一个数据包的下一次发送时间。可以理解的，若UPF接收到第一指示信息时，第一业务流的数据包还没有开始发送，则UPF可以等到第一业务流的数据包开始发送后，检测第一业务流的特征，或者应用的 特征。It can be understood that the SMF can configure different detection windows for different applications. In addition, for method 3, when the UPF detects the characteristics of the first service flow or the characteristics of the application, the data packets of the first service flow have already started to be sent. That is to say, when the SMF receives the first characteristic information, the data packets of the first service flow have already started to be sent. In this case, the first feature information reported by the UPF may include the start sending time of at least one frame of the first service flow, and the SMF determines the next sending time of at least one data packet of the first service flow.

可以理解的，本申请实施例中，SMF确定了第一调度信息后，可以分别向第一终端和AF发送第一调度信息。SMF也可以向第一终端发送第一调度信息，再通过第一终端向AF发送第一调度信息。SMF还可以向AF发送第一调度信息，再通过AF向第一终端发送第一调度信息。应理解，若第一业务流是上行业务流，则SMF或第一终端可以不向AF发送第一调度信息，若第一业务流是下行业务流，则SMF或AF可以不向第一终端发送第一调度信息。It can be understood that, in the embodiment of the present application, after the SMF determines the first scheduling information, it may send the first scheduling information to the first terminal and the AF respectively. The SMF may also send the first scheduling information to the first terminal, and then send the first scheduling information to the AF through the first terminal. The SMF may also send the first scheduling information to the AF, and then send the first scheduling information to the first terminal through the AF. It should be understood that if the first service flow is an uplink service flow, the SMF or the first terminal may not send the first scheduling information to the AF, and if the first service flow is a downlink service flow, the SMF or AF may not send the first scheduling information to the first terminal.

Specifically, as shown in FIG. 11 , the method shown in FIG. 7 further includes S1106-S1107.
S1106：SMF获取第二小区的信息。S1106: The SMF acquires the information of the second cell.
其中，第二小区的信息可以用于标识第二小区。第二小区可以是第一RAN设备的小区，也可以不是第一RAN设备的小区。例如，第二小区可以是第二RAN设备的小区，第二RAN设备与第一RAN设备不同。第二RAN设备可以是图2中的接入网设备205。Wherein, the information of the second cell may be used to identify the second cell. The second cell may be the cell of the first RAN device, or may not be the cell of the first RAN device. For example, the second cell may be a cell of a second RAN device, and the second RAN device is different from the first RAN device. The second RAN device may be the access network device 205 in FIG. 2 .
示例性的，若第二小区是第一RAN设备的小区，则第一RAN设备可以向SMF发送第二小区的信息，相应的，SMF可以接收来自第一RAN设备的第二小区的信息。例如，第一RAN设备通过AMF向SMF发送第二小区的信息，相应的，SMF通过AMF接收来自第一RAN设备的第二小区的信息。Exemplarily, if the second cell is a cell of the first RAN device, the first RAN device may send the information of the second cell to the SMF, and correspondingly, the SMF may receive the information of the second cell from the first RAN device. For example, the first RAN device sends the information of the second cell to the SMF through the AMF, and correspondingly, the SMF receives the information of the second cell from the first RAN device through the AMF.
示例性的，若第二小区是第二RAN设备的小区，则第二RAN设备可以向SMF发送第二小区的信息，相应的，SMF可以接收来自第二RAN设备的第二小区的信息。例如，第二RAN设备通过AMF向SMF发送第二小区的信息，相应的，SMF通过AMF接收来自第二RAN设备的第二小区的信息。Exemplarily, if the second cell is a cell of the second RAN device, the second RAN device may send the information of the second cell to the SMF, and correspondingly, the SMF may receive the information of the second cell from the second RAN device. For example, the second RAN device sends the information of the second cell to the SMF through the AMF, and correspondingly, the SMF receives the information of the second cell from the second RAN device through the AMF.
示例性的，SMF也可以向AMF订阅第一终端接入的小区信息。当第一终端接入的小区发生变化(例如，第一终端接入的小区从第一小区切换为第二小区后)，AMF可以向SMF发送第一终端最新接入的小区的信息(例如，第二小区的信息)。Exemplarily, the SMF may also subscribe to the AMF for the cell information accessed by the first terminal. When the cell accessed by the first terminal changes (for example, after the cell accessed by the first terminal is switched from the first cell to the second cell), the AMF may send information about the cell that the first terminal recently accessed to the SMF (for example, information of the second cell).
S1107：SMF根据第一特征信息和第二小区中其他业务流的特征信息确定第二调度信息。S1107: The SMF determines second scheduling information according to the first feature information and feature information of other service flows in the second cell.
其中，第二小区中其他业务流可以为第二小区中、除第一业务流之外的其他业务流。也就是说，SMF获取到第二小区的信息后，可以根据第二小区的信息获取通过第二小区进行传输的其他业务流的特征信息，根据第一特征信息和第二小区中其他业务流的特征信息确定第二调度信息。其中，第二小区中其他业务流包括第三业务流。第三业务流与第一业务流不同。第三业务流可以是第一终端的业务流，也可以是除第一终端之外，接入第二小区中的其他终端的业务流。第三业务流的数据包已经开始发送或者还未开始发送。Wherein, the other service flows in the second cell may be other service flows in the second cell except the first service flow. That is to say, after the SMF obtains the information of the second cell, it can obtain the feature information of other service flows transmitted through the second cell according to the information of the second cell, and according to the first feature information and the information of other service flows in the second cell The characteristic information determines the second scheduling information. Wherein, other service flows in the second cell include the third service flow. The third service flow is different from the first service flow. The third service flow may be a service flow of the first terminal, or may be a service flow of other terminals accessing the second cell except the first terminal. The data packets of the third service flow have started to be sent or have not yet started to be sent.
本申请实施例中，第三业务流的第三特征信息可以用于指示第三业务流的带宽、周期和第三业务流的至少一个数据包的发送时间。第三特征信息可以使得SMF恢复出第三业务流的数据包的发送规律。或者说，第三特征信息至少可以使得SMF恢复出第三业务流中、较大帧的发送规律。In this embodiment of the present application, the third characteristic information of the third service flow may be used to indicate the bandwidth and period of the third service flow, and the sending time of at least one data packet of the third service flow. The third feature information can enable the SMF to recover the sending rule of the data packets of the third service flow. In other words, the third characteristic information can at least enable the SMF to recover the sending rule of the larger frame in the third service flow.
一种可能的实现方式，第三特征信息是SMF在S1107之前获取的。SMF获取第三特征信息的过程与SMF获取第一特征信息的过程类似，可以参考上述SMF获取第一特征信息的介绍，在此不做赘述。In a possible implementation manner, the third feature information is acquired by the SMF before S1107. The process for the SMF to acquire the third feature information is similar to the process for the SMF to acquire the first feature information. You can refer to the above-mentioned introduction of the SMF for acquiring the first feature information, which will not be repeated here.
本申请实施例中，第二调度信息可以用于确定在第二小区中第一业务流的至少一个数据包的下一次发送时间。例如，第二调度信息可以包括第一业务流的至少一个数据包的下一次发送时间，或者，第二调度信息可以指示至少一个时间区间，第一业务流的至少一个数据包的下一次发送时间可以位于该时间区间内，或者，第二调度信息可以指示第一业务流的至少一个数据包的发送时间的调整时间，例如，第一业务流的至少一个数据包推迟10ms进行发送。In this embodiment of the present application, the second scheduling information may be used to determine a next sending time of at least one data packet of the first service flow in the second cell. For example, the second scheduling information may include the next sending time of at least one data packet of the first service flow, or the second scheduling information may indicate at least one time interval, the next sending time of at least one data packet of the first service flow It may be within the time interval, or the second scheduling information may indicate the adjustment time of the sending time of at least one data packet of the first service flow, for example, the sending of at least one data packet of the first service flow is delayed by 10 ms.
可选的，第二调度信息还可以包括编码率，和/或，调制阶数。若第一业务流具有高可靠性需求，则SMF可以确定一个较低的编码率或较低的调制阶数。Optionally, the second scheduling information may further include a coding rate and/or a modulation order. If the first service flow has a high reliability requirement, the SMF can determine a lower coding rate or a lower modulation order.
可以理解的，SMF根据第一特征信息和第二小区中其他业务流的特征信息确定第二调度信息的过程，与SMF根据第一特征信息和第一小区中其他业务流的特征信息确定第一调度信息的过程类似。因此S1107的介绍可以参考上述S702中对应的描述，在此不做赘述。It can be understood that the process of the SMF determining the second scheduling information according to the first characteristic information and characteristic information of other service flows in the second cell is different from the process of the SMF determining the first scheduling information according to the first characteristic information and characteristic information of other service flows in the first cell. The process of scheduling information is similar. Therefore, for the introduction of S1107, reference may be made to the corresponding description in S702 above, and details are not repeated here.
可以理解的，S1107之后，SMF可以向第一RAN设备、第二RAN设备、第一终端或AF发送第二调度信息。这一过程可以参考上述S1102-S1103、S1104或S1105中对应的描述。需要说明的是，SMF向第二RAN设备发送第二调度信息，可以使得第二RAN设备为第一终端预留资源。该过程可以发生在第一终端已经切换到第二小区之 后，或者，发生在第一终端切换到第二小区之前。It can be understood that after S1107, the SMF may send the second scheduling information to the first RAN device, the second RAN device, the first terminal or the AF. For this process, reference may be made to the corresponding descriptions in S1102-S1103, S1104 or S1105 above. It should be noted that, the SMF sends the second scheduling information to the second RAN device, which may cause the second RAN device to reserve resources for the first terminal. This procedure may take place after the first terminal has been handed over to the second cell, or before the first terminal is handed over to the second cell.
示例性的，在基于Xn接口的切换过程中，第二RAN设备可以在路径切换请求(path switch request)中将第二小区的信息通过AMF发送给SMF，SMF可以在切换请求的响应消息中将第二调度信息通过AMF发送给第二RAN设备。Exemplarily, in the handover process based on the Xn interface, the second RAN device can send the information of the second cell to the SMF through the AMF in the path switch request (path switch request), and the SMF can send the information of the second cell to the SMF in the response message of the handover request. The second scheduling information is sent to the second RAN device through the AMF.
示例性的，在基于N2的切换的过程中，SMF可以从第一RAN设备获取第二小区的信息(通过AMF)，并在切换请求消息中将第二调度信息发送给第二RAN设备(通过AMF)。这样，在切换准备阶段，第二RAN设备即可以根据第二调度信息为第一终端预留资源，使得第一终端可以根据预留的资源及时接收或发送第一业务流的数据包。Exemplarily, in the process of handover based on N2, the SMF can obtain the information of the second cell from the first RAN device (via the AMF), and send the second scheduling information to the second RAN device (via the AMF) in the handover request message AMF). In this way, in the handover preparation stage, the second RAN device can reserve resources for the first terminal according to the second scheduling information, so that the first terminal can receive or send data packets of the first service flow in time according to the reserved resources.
或者，若第一终端还未切换到第二小区，则SMF可以向第一RAN设备发送第二调度信息，后续，第一RAN设备可以向第二RAN设备发送第二调度信息，以便第二RAN设备为第一终端预留资源。例如，第一RAN设备在准备切换前先将第二小区的信息发送给SMF，并从SMF接收第二调度信息，在第一RAN设备向第二RAN设备发送的切换信息中包括第二调度信息。可以理解的，若第一RAN设备在接收到第二调度信息之前，已经根据第一调度信息为第一终端预留了资源。第一RAN设备接收到第二调度信息后，可以根据第二调度信息重新为第一终端预留资源。Or, if the first terminal has not been handed over to the second cell, the SMF may send the second scheduling information to the first RAN device, and subsequently, the first RAN device may send the second scheduling information to the second RAN device, so that the second RAN The device reserves resources for the first terminal. For example, the first RAN device sends the information of the second cell to the SMF before preparing for handover, and receives the second scheduling information from the SMF, and includes the second scheduling information in the handover information sent by the first RAN device to the second RAN device . It can be understood that if the first RAN device has reserved resources for the first terminal according to the first scheduling information before receiving the second scheduling information. After receiving the second scheduling information, the first RAN device may re-reserve resources for the first terminal according to the second scheduling information.
除了上述方法之外，SMF也可以在小区切换完成后，通过更新消息将第二调度信息发送给第二RAN设备，不予限制。In addition to the above method, the SMF may also send the second scheduling information to the second RAN device through an update message after the cell handover is completed, without limitation.
一种可能的实现方式，若第二小区为第一RAN设备的小区，则SMF可以通过更新消息将第二调度信息发送给第一RAN设备。可以理解的，若第一RAN设备在接收到第二调度信息之前，已经根据第一调度信息为第一终端预留了资源。第一RAN设备接收到第二调度信息后，可以根据第二调度信息重新为第一终端预留资源。In a possible implementation manner, if the second cell is a cell of the first RAN device, the SMF may send the second scheduling information to the first RAN device through an update message. It can be understood that if the first RAN device has reserved resources for the first terminal according to the first scheduling information before receiving the second scheduling information. After receiving the second scheduling information, the first RAN device may re-reserve resources for the first terminal according to the second scheduling information.
可以理解的，上述S1106-S1107中，在第一终端已经或即将从第一RAN设备的第一小区切换至第二小区的情况下，SMF可以获取第二小区的信息，并根据第一特征信息和第二小区中其他业务流的特征信息，确定第二小区中第一业务流的至少一个数据包的下一次发送时间，使得第二小区中的业务流的数据包可以错峰发送，从而减少空口拥塞的情况出现，降低数据丢包率和数据的传输时延，提高用户体验。It can be understood that in the above S1106-S1107, when the first terminal has been or is about to be handed over from the first cell of the first RAN device to the second cell, the SMF can obtain the information of the second cell, and according to the first feature information and the characteristic information of other service flows in the second cell, determine the next sending time of at least one data packet of the first service flow in the second cell, so that the data packets of the service flow in the second cell can be sent on a staggered peak, thereby reducing Air interface congestion occurs, reducing the data packet loss rate and data transmission delay, and improving user experience.
