The granularity of the measurements of the third access network device may be one or more. The second measured parameter may be one or more. The first access network device sends the second message to the second access network device, and the second access network device forwards the second message to the third access network device according to the measurement quantity in the second message. Of course, the second message may also be referred to as a measurement configuration message, which is not limited by the embodiment.

The execution sequence of S501, S502 and S503, 504 is not limited, and S501, S502 may be executed in sequence with S503, 504; or can be executed in parallel; only the second access network device may perform the measurement, that is, perform S501, S502; it is also possible that only the third access network device performs the measurements, i.e. S503, S504.

S505a, the third access network device sends the measurement result of the third access network device to the second access network device.

And the third access network equipment reports the measurement result of the third access network equipment through the second access network equipment.

S506a, the second access network device sends the measurement result of the second access network device and/or the measurement result of the third access network device to the first access network device.

The second access network device sends the measurement result of the second access network device to the first access network device, and when the third access network device reports the measurement result of the third access network device to the second access network device, the measurement result of the third access network device is forwarded to the first access network device.

S507a, the first access network device using the measurement result of the second access network device, and/or the measurement result of the third access network device.

In implementation a1, the first access network device configures or reconfigures the protocol stack parameters of the second access network device according to the measurement result of the second access network device (reconfiguration refers to modifying configuration). The protocol stack parameters may be one or more of: parameters of RRC, SDAP, PDCP, RLC, MAC and PHY protocol stacks.

The first access network device manages one or more second access network devices connected thereto. After receiving the measurement result of the second access network device, the first access network device configures one or more protocol stack parameters of the second access network device according to the measurement result, or may be referred to as performing parameter training.

In a specific implementation, a first access network device receives one or more measurement results of one or more measurement granularities of a second access network device. For example, the measurement result is the packet loss rate of one or more QoS flows, and if the packet loss rate of a certain QoS flow is higher, the number of times of retransmission of the data packet needs to be set in the RLC layer, and the MAC SDU includes multiple data packets for retransmission. Of course, for the packet loss rate, other protocol stack parameters may also be set, which is only an example and is not limited herein.

Implementation a2, the first access network device configures the protocol stack parameters of the third access network device according to the measurement result of the third access network device, for example, configures RRC, SDAP, PDCP, RLC, MAC, and PHY layers.

In a specific implementation, the first access network device may be independently configured, or may be located on the second access network device (for example, the first access network device is a complete base station, the second access network device is a CU, and the third access network device is a DU). For example, when a first access network device is independently configured, it connects to one or more second access network devices, each of which in turn connects to one or more third access network devices. The first access network device may configure the protocol stack parameters of the plurality of third access network devices connected to each second access network device, or may configure the protocol stack parameters of the plurality of third access network devices connected to any one second access network device. For another example, when the first access network device is located on the second access network device, the first access network device may configure one or more protocol stack parameters of one or more third access network devices connected to the second access network device according to measurement results of the one or more third access network devices.

For example, the first access network device is configured independently, and the first access network device receives measurement results of a plurality of third access network devices connected to the second access network device. The measurement results include packet delay data for one or more bearers. The measurement result shows that the delay of one or more data packets of the bearer managed by one of the third access network devices is serious, and if the delay exceeds a set threshold, the first access network device sets the priority of the bearer or the logical channel to the MAC layer of the third access network device, so that the data packets of the bearer are transmitted preferentially to reduce the delay of the data packets. Or the first access network device selects another third access network device for the one or more bearers to reduce the delay of the data packets.

In implementation a3, the first access network device configures the protocol stack parameter of the first access network device according to the measurement result, and notifies the second access network device of the configuration result.

In a specific implementation, the first access network device obtains measurement results of one or more second access network devices connected thereto and measurement results of one or more third access network devices connected to each second access network device, and these measurement results show that the first access network device needs to adjust protocol stack parameters from an overall level, so that the first access network device can macroscopically configure one or more protocol stack parameters of the first access network device itself, and can notify the configuration results to the one or more second access network devices connected thereto. Further, the second access network device may inform one or more third access network devices to which it is connected of the configuration result.

the first access network device informs other second access network devices in the plurality of second access network devices of the configuration parameters for the any one second access network device.

In a specific implementation, the adjustment of the protocol stack parameters of one second access network device may affect other second access network devices. Therefore, after configuring the protocol stack parameters of any one second access network device according to the measurement result of the second access network device, the first access network device may notify the other second access network devices of the configuration parameters. For example, after the first access network device configures the random access parameter for a certain second access network device, the first access network device notifies other second access network devices of the configuration parameter at the same time. The first access network equipment directly informs other second access network equipment, or the second access network equipment informs other second access network equipment through interface signaling. For another example, the first access network device may reset the transmission mode to the RLC layer of the second access network device from the unacknowledged mode to the acknowledged mode. After the RLC layer of the second access network device is reset, the first access network device notifies the set RLC mode to other second access network devices, and after the other second access network devices obtain the configuration parameter notification, the protocol stack parameters may not be adjusted, and the protocol stack parameters are normally transmitted.

In implementation a5, the first access network device configures a protocol stack parameter of any third access network device according to a measurement result of any third access network device;

the first access network device informs other third access network devices in the plurality of third access network devices of the configuration parameters for the any third access network device.

In a specific implementation, for example, when the first access network device is independently configured, the protocol stack parameters are adjusted for one or more third access network devices of one of the second access network devices. The adjustment of protocol stack parameters of one third access network device may affect other third access network devices. Therefore, after the first access network device configures the protocol stack parameters of any third access network device according to the measurement result of the third access network device, the first access network device may notify the other third access network devices of the configuration parameters.

S507 a', the second access network device using the measurement result of the second access network device, and/or the measurement result of the third access network device.

In implementation B1, the second access network device configures the protocol stack parameter of the second access network device according to the measurement result of the second access network device, and notifies the third access network device of the configuration result.

In a specific implementation, the second access network device obtains measurement results of one or more third access network devices connected thereto, and these measurement results show that the second access network device needs to adjust protocol stack parameters from an overall level, so that the second access network device can macroscopically configure one or more protocol stack parameters of the second access network device itself, and can notify the configuration results to the one or more third access network devices connected thereto.

Implementation B2, where the second access network device configures the protocol stack parameters of the one or more third access network devices according to the measurement result of the one or more third access network devices.

In a specific implementation, the second access network device obtains a measurement result of one or more third access network devices connected thereto, and needs to configure a protocol stack parameter of each third access network device, so that the second access network device may configure one or more protocol stack parameters of the one or more third access network devices according to the measurement result of the one or more third access network devices.

In implementation B3, the second access network device configures the protocol stack parameters of any third access network device according to the measurement result of any third access network device;

the second access network device informs other third access network devices in the plurality of third access network devices of the configuration parameters for the any one of the third access network devices.

In a specific implementation, the adjustment of the protocol stack parameters of one third access network device may affect other third access network devices. Therefore, after the second access network device configures the protocol stack parameters of any third access network device according to the measurement result of the third access network device, the second access network device may notify the other third access network devices of the configuration parameters. For example, the transmission block size of a certain third access network device is too large, and occupies too much bandwidth from the third access network device to the second access network device, resulting in a serious packet loss rate of other third access network devices. The second access network device may reset the transport block size to the RLC layer of the third access network device, reducing its transport block size and thus its occupied bandwidth. After the second access network device resets the size of the transmission block to the RLC layer of the third access network device, the second access network device notifies the other third access network devices of the size of the transmission block, and after the other third access network devices obtain the configuration parameter notification, the protocol stack parameters may not be adjusted, and the transmission is performed normally.
