The processor 20 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 23 and calling data stored in the memory 23, thereby performing overall monitoring of the mobile phone. Alternatively, processor 20 may include one or more processing units. Optionally, the processor 20 may integrate an application processor and a modem processor, wherein the application processor mainly processes an operating system, a user interface, an application program, and the like; the modem processor handles primarily wireless communications.

For example, the downlink information of the base station is received and then processed by the processor 20; in addition, the uplink data is transmitted to the base station. Typically, the RF circuit includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), and a duplexer.

Specifically, the input unit 24 may include a touch screen 241 and other input devices 242. The touch screen 241, also referred to as a touch panel, may collect touch operations of a user (e.g., operations of the user on or near the touch screen 241 using any suitable object or accessory such as a finger, a stylus, etc.) thereon or nearby, and drive the corresponding connection device according to a preset program. Alternatively, the touch screen 241 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 20, and can receive and execute commands sent by the processor 20. In addition, the touch screen 241 may be implemented in various types, such as resistive, capacitive, infrared, and surface acoustic wave.

Although in fig. 2 the touch screen 241 and the display panel 251 are shown as two separate components to implement the input and output functions of the mobile phone, in some embodiments, the touch screen 241 and the display panel 251 may be integrated to implement the input and output functions of the mobile phone.

In one aspect, the audio circuit 26 may transmit the converted electrical signal of the received audio data to the speaker 261, and the converted electrical signal is converted into a sound signal by the speaker 261 and output. On the other hand, the microphone 262 converts the collected sound signals into electrical signals, which are received by the audio circuit 26 and converted into audio data, which are then output by the processor 20 to the RF circuit 21 for transmission to, for example, another cellular phone, or output by the processor 20 to the memory 23 for further processing.

With reference to the communication system shown in fig. 1, the following completely describes the delay reporting method provided in the embodiment of the present invention from the perspective of interaction between the UE and the network device in the communication system, so as to explain a process of reporting (or sending) the delay of the uplink PDCP layer corresponding to at least one RB by the UE.

As shown in fig. 4, the method for reporting a delay provided in the embodiment of the present invention may include S101 to S108.

S101, the network equipment sends RRC reconfiguration information to the UE.

The RRC reconfiguration message includes network slice configuration information and delay threshold information, where the network slice configuration information includes identification information of each of the plurality of network slices, the delay threshold information includes a delay threshold corresponding to each of the plurality of network slices, and the network slice configuration information is used to instruct the UE to acquire an uplink PDCP layer delay corresponding to at least one RB included in each of the plurality of network slices.

It should be understood that one network slice may contain (or correspond to) at least one RB, and one RB may correspond to one uplink PDCP layer delay; the uplink PDCP layer delay corresponding to at least one RB included in a network slice may be a plurality of values, that is, the uplink PDCP layer delay corresponding to each RB in the at least one RB (i.e., a plurality of delays), and the uplink PDCP layer delay corresponding to at least one RB included in the network slice may be a value (i.e., a delay), which may optionally be an average value of the uplink PDCP layer delays corresponding to each RB in the at least one RB, and specifically, the number or form of the values of the uplink PDCP layer delay corresponding to the at least one RB is determined by the UE.

S102, the UE receives the RRC reconfiguration message sent by the network equipment.

S103, the UE sends an RRC reconfiguration complete message to the network equipment.

Wherein, the RRC reconfiguration complete message is used to notify the network device that the UE is successfully configured.

It should be understood that the UE configuration success is specifically that the UE has completed the related configuration, and the related configuration is used to support the UE to execute the content indicated in the network slice configuration information, that is, to support the UE to acquire the uplink PDCP layer delay corresponding to at least one RB included in each of the plurality of network slices.

S104, the network equipment receives the RRC reconfiguration complete message sent by the UE.

S105, the UE acquires the uplink PDCP time delay corresponding to each RB in at least one RB contained in the target network slice.

Wherein the target network slice is one of the plurality of network slices.

It is understood that the UE starts to perform S105 after completing the above-described related configuration.

S106, the UE determines whether the target delay difference value is larger than or equal to a delay threshold corresponding to the target network slice.

The target time delay difference is a difference between a maximum time delay and a minimum time delay, the maximum time delay is a maximum value in uplink PDCP layer time delays corresponding to RBs in at least one RB included in a target network slice, and the minimum time delay is a minimum value in the uplink PDCP layer time delays corresponding to RBs in at least one RB included in the target network slice.

With reference to the foregoing description of the embodiments, it should be understood that one network slice (e.g., a target network slice) may correspond to at least one RB, and each RB in the at least one RB may correspond to one uplink PDCP layer delay, that is, the target network slice may correspond to at least one uplink PDCP layer delay, where the maximum delay is an uplink PDCP layer delay with a largest value among the at least one uplink PDCP layer delay, and similarly, the minimum delay is an uplink PDCP layer delay with a smallest value among the at least one uplink PDCP layer delay, and then the UE may determine the target delay difference based on the uplink PDCP layer delay with the largest value and the uplink PDCP layer delay with the smallest value, and further determine whether the target delay difference is greater than or equal to a delay threshold corresponding to the target network slice.

Illustratively, table 1 below shows the uplink PDCP layer delays corresponding to RBs included in the target network slice, where the target network slice includes 4 RBs, i.e., a first RB, a second RB, a third RB, and a fourth RB, and the uplink PDCP layer delays corresponding to the 4 RBs are 100ms (milliseconds), 50ms, 200ms, and 150ms, respectively, as shown in table 1.

TABLE 1

RB contained in target network slice	Uplink PDCP layer time delay (ms)
		First RB	100
Second RB	50
		Third RB	200
Fourth RB	150

With reference to table 1, the UE may determine that the target delay difference is 150ms, and assume that the delay threshold corresponding to the target network slice is 100ms, the UE determines that the target delay difference is greater than the delay threshold corresponding to the target network slice.

S107, when the target delay difference value is larger than or equal to the delay threshold value corresponding to the target network slice, the UE sends a first delay report message to the network equipment.

The first time delay reporting message includes an uplink PDCP layer time delay corresponding to each RB in at least one RB included in the target network slice.

It should be understood that, when the target delay difference is greater than or equal to the delay threshold corresponding to the target network slice, it indicates that the performance difference of each RB in the at least one RB included in the target network slice is relatively large, and the network device needs to acquire the uplink PDCP layer delay corresponding to each RB in the at least one RB, and further optimize each RB in the at least one RB.

S108, the network equipment receives a first time delay report message sent by the UE.

In this way, the network device may obtain the uplink PDCP layer delay corresponding to each RB in at least one RB included in the target network slice.

In the delay reporting method provided by the embodiment of the present invention, a network device sends an RRC reconfiguration message to a UE, where the RRC reconfiguration message includes network slice configuration information and delay threshold information, the network slice configuration information includes identification information of each of a plurality of network slices, the delay threshold information includes a delay threshold corresponding to each of the plurality of network slices, and the network slice configuration information is used to instruct the UE to acquire an uplink PDCP layer delay corresponding to at least one RB included in each of the plurality of network slices; the UE receives an RRC reconfiguration message sent by the network equipment and acquires the time delay of an uplink PDCP layer corresponding to each RB in at least one RB contained in a target network slice; then, the UE determines whether a target delay difference (i.e. the difference between the maximum uplink PDCP layer delay and the minimum uplink PDCP layer delay) is greater than or equal to a delay threshold corresponding to the target network slice; when the target delay difference value is greater than or equal to the delay threshold value corresponding to the target network slice, that is, when it is determined that the performance difference of each RB in at least one RB included in the target network slice is large, the UE sends a first delay report message to the network device, that is, the UE sends the uplink PDCP layer delay corresponding to each RB in at least one RB included in the target network slice to the network device; in this way, the network device may obtain the uplink PDCP layer delay corresponding to each RB in at least one RB included in the target network slice. In the embodiment of the invention, the network equipment sends the relevant configuration to the terminal, and the terminal can send the uplink PDCP layer time delay corresponding to each RB corresponding to the target network slice to the network equipment after finishing the corresponding determination process (namely determining that the target time delay difference value is greater than or equal to the time delay threshold value corresponding to the target network slice), so that the actual measurement process of the uplink PDCP layer time delay can be completely and effectively reflected, and the efficiency of network optimization can be further improved.

In an implementation manner of the embodiment of the present invention, after the step S106, the method for reporting a time delay further includes a step a to a step B.

And step A, the UE sends a second time delay report message to the network equipment under the condition that the target time delay difference value is smaller than the time delay threshold value corresponding to the target network slice.

The second time delay reporting message includes an average uplink PDCP layer time delay corresponding to the target network slice, where the average uplink PDCP layer time delay is an average value of uplink PDCP layer time delays corresponding to RBs in at least one RB included in the target network slice.

It can be understood that, when the target delay difference value is smaller than the delay threshold corresponding to the target network slice, which indicates that the performance difference of each RB in the at least one RB included in the target network slice is smaller, the network device may obtain a value used for characterizing the delay of the at least one uplink PDCP layer, that is, the average uplink PDCP layer delay.

And step B, the network equipment receives a second time delay reporting message sent by the UE.

In this way, the network device may obtain the average uplink PDCP layer delay corresponding to the target network slice, that is, the average value of the uplink PDCP layer delay corresponding to each RB in at least one RB included in the target network slice.

Optionally, the delay threshold corresponding to the target network slice may be 0, and when the delay threshold corresponding to the target network slice is 0, regardless of the size of the target delay difference, the UE sends the first delay report message to the network device, that is, sends, to the network device, the uplink PDCP layer delay corresponding to each RB in at least one RB included in the target network slice; similarly, when the delay threshold corresponding to the target network slice is infinite, regardless of the size of the target delay difference, the network device may also obtain the uplink PDCP layer delay corresponding to each RB in at least one RB included in the target network slice.

In an implementation manner of the embodiment of the present invention, before the above S101, the RRC connection between the UE and the network device may be in an idle state, so that the UE first needs to send an RRC establishment request message to the network device, and after the RRC establishment is completed, the network device and the UE may execute the delay reporting method provided in the above embodiment of the present invention.
