Network slice: in a 5G network, the concept of network slicing is introduced, where a network slice is a set of network functions, resources running these network functions, and specific configurations of these network functions, and a network slice may constitute an end-to-end logical network. In the 5G network, different types of network slices may be selected for the terminal according to the service requirement of the terminal, and exemplary network slices may include different types of network slices applied to a mobile bandwidth (mobile broad bank, MBB) scene, an internet of things (internet of things, IOT) scene, a mobile edge computing (mobile edge computing, MEC) scene, and the like, where each network slice includes respective service functions (such as an access and mobility management function (access and mobility management function, AMF), a user plane function (user plane function, UPF), a policy control function (policy control function, PCF), and the like).

Based on the problems existing in the background technology, the embodiment of the invention provides a time delay reporting method and device, and network equipment sends RRC reconfiguration information to UE, wherein the RRC reconfiguration information comprises network slice configuration information and time delay threshold information, the network slice configuration information comprises identification information of each of a plurality of network slices, the time delay threshold information comprises time delay thresholds corresponding to each of the plurality of network slices, and the network slice configuration information is used for indicating the UE to acquire the time delay of an uplink PDCP layer corresponding to at least one RB contained in each of the plurality of network slices; the UE receives an RRC reconfiguration message sent by the network equipment and acquires uplink PDCP layer time delay corresponding to each RB in at least one RB contained in the target network slice; then, the UE determines whether the target delay difference value (namely, the difference value between the maximum uplink PDCP layer delay and the minimum uplink PDCP layer delay) is larger than or equal to a delay threshold value corresponding to the target network slice; and when the target delay difference value is greater than or equal to a 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 contained in the target network slice is large, the UE sends a first delay report message to the network device, that is, the UE sends an uplink PDCP layer delay corresponding to each RB in at least one RB contained in the target network slice to the network device; thus, the network device can 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 after the terminal completes the corresponding determining process (namely, the determined target delay difference value is greater than or equal to the delay threshold value corresponding to the target network slice), the terminal can send the uplink PDCP layer delay corresponding to each RB corresponding to the target network slice to the network equipment, so that the actual measuring process of the uplink PDCP layer delay can be completely and effectively reflected, and the network optimization efficiency can be improved.

The method and apparatus for reporting delay provided in the embodiments of the present invention may be applied to a wireless communication system, for example, a 5G communication system is shown in fig. 1, where the 5G communication system includes a UE 101 and a network device 102, and communications are performed between the UE 101 and the network device 102, for example, the network device 102 sends an RRC reconfiguration message to the UE 101, and the UE 101 sends an RRC reconfiguration complete message to the network device 102. In general, in practical applications, the connection between the above-mentioned devices or service functions may be a wireless connection, and for convenience and intuitiveness, the connection relationship between the devices is schematically shown by a solid line in fig. 1.

In the embodiment of the present invention, the UE shown in fig. 1 is taken as an example of a mobile phone, and the hardware structure of the UE provided in the embodiment of the present invention is described in an exemplary manner. As shown in fig. 2, a mobile phone provided in an embodiment of the present invention includes: a processor 20, a Radio Frequency (RF) circuit 21, a power supply 22, a memory 23, an input unit 24, a display unit 25, an audio circuit 26, and the like. Those skilled in the art will appreciate that the structure of the handset shown in fig. 2 is not limiting of the handset, and may include more or fewer components than those shown in fig. 2, or may combine some of the components shown in fig. 2, or may differ in arrangement of components from those shown in fig. 2.

The processor 20 is a control center of the mobile phone, and connects various parts of the entire mobile phone using various interfaces and lines, and performs various functions and processes of the mobile phone by running 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, the processor 20 may include one or more processing units. Alternatively, the processor 20 may integrate an application processor and a modem processor, wherein the application processor primarily processes operating systems, user interfaces, application programs, and the like; the modem processor primarily handles wireless communications. It will be appreciated that the modem processor described above may also be a processor that exists separately from processor 20.

The RF circuit 21 may be used to receive and transmit signals during the course of receiving and transmitting information or a conversation. For example, after receiving the downlink information of the base station, the downlink information is processed by the processor 20; and, the uplink data is transmitted to the base station. Typically, RF circuitry includes, but is not limited to, antennas, at least one amplifier, transceivers, couplers, low noise amplifiers (Low Noise Amplifier, LNAs), and diplexers, among others. In addition, the handset may also communicate wirelessly with other devices in the network via the RF circuitry 21. The wireless communication may use any communication standard or protocol including, but not limited to, global system for mobile communications (Global System of Mobile Communication, GSM), general packet radio service (General Packet Radio Service, GPRS), code division multiple access (Code Division Multiple Access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), LTE, email, short message service (Short Messaging Service, SMS), and the like.

The power supply 22 may be used to power the various components of the handset and the power supply 22 may be a battery. Alternatively, the power source may be logically connected to the processor 20 through a power management system, so that functions of managing charging, discharging, and power consumption are performed through the power management system.

The memory 23 may be used to store software programs and modules, and the processor 20 executes various functional applications and data processing of the cellular phone by running the software programs and modules stored in the memory 23. The memory 23 may mainly include a storage program area that may store an operating system, application programs required for at least one function (such as a sound playing function, an image playing function, etc.), and a storage data area; the storage data area may store data (such as audio data, image data, phonebook, etc.) created according to the use of the cellular phone, etc. In addition, memory 23 may include high-speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid-state storage device.

The input unit 24 is operable to receive input numeric or character information and to generate key signal inputs related to user settings and function control of the handset. In particular, 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 thereon or thereabout by a user (e.g., operations of the user on the touch screen 241 or thereabout using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a predetermined 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 azimuth 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 detection device and converts it into touch point coordinates, which are then sent to the processor 20, and can receive commands from the processor 20 and execute them. Further, the touch screen 241 may be implemented in various types such as resistive, capacitive, infrared, and surface acoustic wave. Other input devices 242 may include, but are not limited to, one or more of a physical keyboard, function keys (e.g., volume control keys, power switch keys, etc.), a trackball, a mouse, and a joystick, among others.

The display unit 25 may be used to display information input by a user or information provided to the user and various menus of the mobile phone. The display unit 25 may include a display panel 251. Alternatively, the display panel 251 may be configured in the form of a liquid crystal display (Liquid Crystal Display, LCD), an Organic Light-emitting Diode (OLED), or the like. Further, the touch screen 241 may cover the display panel 251, and when the touch screen 241 detects a touch operation thereon or thereabout, it is transferred to the processor 20 to determine the type of touch event, and then the processor 20 provides a corresponding visual output on the display panel 251 according to the type of touch event. Although in fig. 2, the touch screen 241 and the display panel 251 are two separate components to implement the input and output functions of the mobile phone, in some embodiments, the touch screen 241 may be integrated with the display panel 251 to implement the input and output functions of the mobile phone.

Audio circuitry 26, speaker 261, and microphone 262 for providing an audio interface between a user and the handset. In one aspect, the audio circuit 26 may transmit the received electrical signal after conversion of the audio data to the speaker 261, where the electrical signal is converted to a sound signal by the speaker 261 for 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 output to the RF circuit 21 through the processor 20 for transmission to, for example, another cellular phone, or which are output to the memory 23 through the processor 20 for further processing.

Optionally, the handset as shown in fig. 2 may also include various sensors. Such as gyroscopic sensors, hygrometric sensors, infrared sensors, magnetometer sensors, etc., are not described in detail herein.

By way of example, taking the network device 102 in fig. 1 as a commonly used base station, the hardware structure of the network device 102 provided in the embodiment of the present invention is described. As shown in fig. 3, a base station provided by an embodiment of the present invention may include: 30 parts and 31 parts. The 30 part is mainly used for receiving and transmitting radio frequency signals and converting the radio frequency signals and baseband signals; the 31 part is mainly used for baseband processing, control of the base station and the like. Section 30 may be generally referred to as a transceiver unit, transceiver circuitry, or transceiver, etc. Portion 31 is typically the control center of the base station and may be generally referred to as a processing unit.

The transceiver unit of part 30, which may also be referred to as a transceiver, or transceiver, etc., comprises an antenna and a radio frequency unit, or only a radio frequency unit or part thereof, wherein the radio frequency unit is primarily intended for radio frequency processing. Alternatively, the device for realizing the receiving function in part 30 may be regarded as a receiving unit, and the device for realizing the transmitting function may be regarded as a transmitting unit, i.e. part 30 includes a receiving unit and a transmitting unit.

In addition, all functions in the 31 portions may be integrated in one chip, or some functions may be integrated in one chip, and some functions may be integrated in one or more other chips, which is not limited by the embodiment of the present invention.

In combination with the communication system shown in fig. 1, the delay reporting method provided by the embodiment of the present invention is fully described below from the perspective of interaction between the UE and the network device in the communication system, so as to illustrate the 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 delay reporting method provided by the embodiment of the present invention may include S101-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 delay thresholds corresponding to each of the plurality of network slices, and the network slice configuration information is used to instruct the UE to obtain delay of an uplink PDCP layer corresponding to at least one RB included in each of the plurality of network slices.

It should be appreciated that one network slice may contain (or correspond to) at least one RB, which may correspond to one uplink PDCP layer delay; the uplink PDCP layer delay corresponding to at least one RB included in one 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), alternatively, the value may 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 an RRC reconfiguration message sent by the network equipment.

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

The RRC reconfiguration complete message is used to notify the network device that the UE configuration is successful.

It should be understood that the UE configuration success is specifically that the UE has completed the relevant configuration, where the relevant configuration is used to support the UE to execute the content indicated in the above 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 completion message sent by the UE.

S105, the UE acquires 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 can be appreciated 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 delay difference is a difference between a maximum delay and a minimum delay, the maximum delay is a maximum value in uplink PDCP layer delays corresponding to each RB in at least one RB contained in the target network slice, and the minimum delay is a minimum value in uplink PDCP layer delays corresponding to each RB in at least one RB contained in the target network slice.

In connection with the above 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, each RB of the at least one RB may correspond to one uplink PDCP layer delay, i.e., the target network slice may correspond to at least one uplink PDCP layer delay, the maximum delay is an uplink PDCP layer delay having a maximum value in the at least one uplink PDCP layer delay, and, similarly, the minimum delay is an uplink PDCP layer delay having a minimum value in the at least one uplink PDCP layer delay, and then the UE may determine the target delay difference value based on the uplink PDCP layer delay having the maximum value and the uplink PDCP layer delay having the minimum value, and further determine whether the target delay difference value is greater than or equal to a delay threshold corresponding to the target network slice.

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

TABLE 1

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

In combination with 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, then the UE determines that the target delay difference is greater than the delay threshold corresponding to the target network slice.

And S107, under the condition that the target delay difference value is greater than or equal to a delay threshold value corresponding to the target network slice, the UE transmits a first delay reporting message to the network equipment.

The first delay report message includes an uplink PDCP layer 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 at least one RB included in the target network slice is greater, and the network device needs to obtain the delay of the uplink PDCP layer corresponding to each RB in the at least one RB, so as to optimize each RB in the at least one RB.

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

Thus, the network device can obtain the uplink PDCP layer delay corresponding to each RB in at least one RB included in the target network slice.

According to the time delay reporting method provided by the embodiment of the invention, a network device sends an RRC reconfiguration message to UE, wherein the RRC reconfiguration message comprises network slice configuration information and time delay threshold information, the network slice configuration information comprises identification information of each of a plurality of network slices, the time delay threshold information comprises time delay thresholds corresponding to each of the plurality of network slices, and the network slice configuration information is used for indicating the UE to acquire time delay of an uplink PDCP layer corresponding to at least one RB contained in each of the plurality of network slices; the UE receives an RRC reconfiguration message sent by the network equipment and acquires uplink PDCP layer time delay corresponding to each RB in at least one RB contained in the target network slice; then, the UE determines whether the target delay difference value (namely, the difference value between the maximum uplink PDCP layer delay and the minimum uplink PDCP layer delay) is larger than or equal to a delay threshold value corresponding to the target network slice; and when the target delay difference value is greater than or equal to a 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 contained in the target network slice is large, the UE sends a first delay report message to the network device, that is, the UE sends an uplink PDCP layer delay corresponding to each RB in at least one RB contained in the target network slice to the network device; thus, the network device can 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 after the terminal completes the corresponding determining process (namely, the determined target delay difference value is greater than or equal to the delay threshold value corresponding to the target network slice), the terminal can send the uplink PDCP layer delay corresponding to each RB corresponding to the target network slice to the network equipment, so that the actual measuring process of the uplink PDCP layer delay can be completely and effectively reflected, and the network optimization efficiency can be improved.

In one implementation manner of the embodiment of the present invention, after S106, the delay reporting method provided by the embodiment of the present invention further includes step a-step B.

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

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

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

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

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

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

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