In the following, to facilitate understanding, technical terms involved in the embodiments of the present disclosure are explained.

1.URLLC

URLLC is a communication technology with ultra-low latency and ultra-high reliability. In terms of latency, URLLC technology can meet the data transmission requirements for user plane and uplink latency as low as 0.5ms between the base station and the terminal. In terms of reliability, URLLC technology can achieve data transmission requirements with a reliability level of 10 ^-5 .

URLLC business is one of the three major application scenarios of 5th generation mobile communication technology (5G). The main application scenarios include but are not limited to: industrial control, equipment automation, Internet of Vehicles, and remote surgery.

Since the URLLC service needs to consider both delay and reliability, the data transmission of the URLLC service usually requires that the probability of the transmission delay being less than a certain threshold reaches a preset threshold value. For example, the probability that the required transmission delay is less than 10ms is greater than 60%.

2. QoS monitoring

QoS monitoring is a technology used to monitor the average delay of data packets. Since the URLLC service has a high delay for data, QoS monitoring technology can be used to monitor the delay of the URLLC service in the URLLC service to determine whether the delay reliability of the URLLC service meets the delay reliability requirements of the service.

QoS monitoring is a new monitoring mechanism proposed in the 3GPP R16 version, which can monitor Control service delays. Currently, QoS monitoring mainly includes: QoS monitoring at the granularity of each QoS flow of each terminal, and the User Plane Part of GPRS Tunnelling Protocol (GTP) of the General Packet Radio Service (GPRS). -U)GTP-U tunnel is granular QoS monitoring.

QoS monitoring is mainly used to monitor the delay between data from the User Plane Function (UPF) to the terminal. Among them, the delay between the UPF and the terminal includes: the uplink and downlink air interface delay, and the uplink and downlink delay between the base station and the UPF. Among them, the uplink and downlink air interface delays are monitored by the base station. The uplink and downlink delays between the base station and UPF are jointly monitored by the base station and UPF.

Specifically, the uplink and downlink delays between the base station and UPF include the following two types: QoS flow level delay, and GTP-U level delay. The following is an example of monitoring the latency at the QoS flow level.

As shown in Figure 2, the monitoring process of the uplink and downlink delays between the base station and the UPF includes the following steps 201 to 205.

Step 201: Access Facilities (AF) sends a first QoS monitoring request to Policy Control Function (PCF). Correspondingly, the PCF receives the first QoS monitoring request from the AF.

The first QoS monitoring request is used to request the PCF to generate a QoS monitoring policy.

Step 202: PCF sends the QoS monitoring policy to the session management function (Session Management function, SMF).

Specifically, after receiving the first QoS monitoring request, the PCF generates an authorized QoS monitoring policy based on the first QoS monitoring request. After this, PCF sends QoS monitoring policy to SMF.

Optionally, the QoS monitoring policy is carried in the Policy and Charging Control (PCC) rules sent by the PCF to the SMF.

Step 203: The SMF monitors the delay of the QoS flow between the terminal and the PCF according to the QoS monitoring policy.

Specifically, SMF activates the above QoS monitoring policy during the process of establishing a Protocol Data Unit (PDU) session or modifying a PDU session. After activating the QoS monitoring policy, SMF monitors the end-to-end upstream and downstream QoS flow delays between the terminal and the PCF according to the QoS monitoring policy.

Step 204: The SMF sends a second QoS monitoring request to the UPF, and sends a third QoS monitoring request to the access network device.

The second QoS monitoring request is used to request the UPF to monitor the QoS flow between the UPF and the access network device. The third QoS monitoring request is used to request the access network device to monitor the QoS flow between the UPF and the access network device.

Optionally, both the second QoS monitoring request and the third QoS monitoring request include: monitoring parameters determined by the SMF based on the authorized QoS monitoring policy obtained from the PCF or from the local configuration.

In a possible implementation manner, the second QoS monitoring request is carried in the N4 signaling sent by the SMF to the UPF. The third QoS monitoring request is carried in the N2 signaling sent by the SMF to the access network device.

Step 205: The access network device and the UPF determine the delay of the QoS flow between the terminal and the UPF based on the second QoS monitoring request and the third QoS monitoring request.

In a possible implementation manner, the access network device initiates uplink (UL)/downlink (DL) delay measurement on the wireless access network side according to the third QoS monitoring request. The access network device reports the UL/DL delay measurement results on the wireless access network side to the UPF in the uplink data packet or the virtual uplink data packet.

Specifically, step 205 can be implemented through the following steps 2051 to 2054.

Step 2051: The UPF sends the data packet to the access network device.

Among them, the data packet includes: Qos Flow Identifier (QFI), QoS Monitoring Packet Indicator (QMP), time T1. The QoS monitoring packet indicator is used to indicate that the packet is used for UL/DL packet delay measurement. Time T1 is the local time when UPF sends the downlink monitoring packet.

In a specific implementation manner, UPF encapsulates the above-mentioned QFI, QoS monitoring packet indicator and time T1 in the message header of the data message. After encapsulation, UPF sends the data message to the access network device.

Step 2052: The access network device receives the data packet and measures the wireless access network side delay.

Specifically, after receiving the data message, the access network device parses the header of the data message and determines the time T1. The access network device determines the local time T2 when the data message is received. After that, the access network equipment starts measuring the UL/DL data packet delay on the wireless access network side.

Step 2053: The access network device reports the monitoring response packet to the UPF.

Specifically, when the access network device receives an uplink packet for this QFI from the terminal, or when the access network device sends a virtual uplink packet as a monitoring response (if not used for uplink packets Delay monitored uplink service packet data), the access network device encapsulates the QMP indicator, the radio access network portion of the uplink/downlink packet delay results, time T1, time T2 and time T3. Among them, time T3 is the time when the access network device sends the monitoring response packet to the UPF through the N3 interface.

Step 2054: The access network device receives the monitoring response packet and determines the delay between the access network device and the UPF.

Specifically, when the access network device receives the monitoring response packet, it records the local time T4, and calculates the time interval between the access network device and the UPF based on the time information contained in the GTP-U header of the received monitoring response packet. Round trip delay.

2.1. Air interface downlink delay

The air interface downlink delay is the average downlink air interface delay between the access network device and the terminal during the statistical period. The definition of the average delay of the downlink air interface between the access network equipment and the terminal in 3GPP is shown in Figure 3 below. The air interface downlink The delay includes four types of delays: downlink delay D1, downlink delay D2, downlink delay D3, and downlink delay D4.

As shown in Figure 3, the above-mentioned downlink delay D1 is the delay between the terminal and the distributed unit (Distributed Unit, DU), and the downlink delay D2 is the radio link control layer (Radio Link Control, RLC) layer of the DU and the DU The delay between the media access control layer (Media Access Control, MAC) layer, the downlink delay D3 is the RLC between the packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer of the central unit (Centralized Unit, CU) and the DU The delay between layers, the downlink delay D4 is the delay between the Service Data Adaptation Protocol (SDAP) layer of the CU and the PDCP layer of the CU.

As shown in Table 1 below, these four delays are explained in the standard protocol.

Table 1. Description of downlink delay

2.2. Air interface uplink delay

The air interface uplink delay is the average uplink air interface delay between the access network device and the terminal during the statistical period. The definition of the average uplink air interface delay between the access network equipment and the terminal in 3GPP is shown in Figure 4 below. The air interface uplink delay includes: uplink delay D1, uplink delay D2.1, and uplink delay D2. 2. Uplink delay D2.3 four kinds of delay.

As shown in Figure 4, the above uplink delay D1 is the delay between the terminal's SDAP layer and the terminal's physical layer (Physical, PHY) layer, the uplink delay D2.1 is the delay between the terminal and DU, and the uplink delay D2.1 is the delay between the terminal and the DU. The delay D2.2 is the delay between the PHY layer of the DU and the RLC layer of the DU. The uplink delay D2.3 is the delay between the RLC layer of the DU and the PDCP layer of the CU. The uplink delay D4.1 is The delay between the CU's PDCP layer and the CU's SDAP layer.

As shown in Table 2 below, these four delays are explained in the standard protocol.

Table 2. Description of uplink delay

The terminology involved in this disclosure has been explained in detail above.

In related technologies, access network equipment usually uses a QoS monitoring mechanism to monitor the delay of data packets, taking the average delay of data packets of the service within the statistical period as the service delay, and then determining the transmission of the service based on the average delay. Whether it meets business transmission requirements.

However, the current URLLC service requires not only a short delay during the transmission process, but also a high reliability (that is, the transmission success rate of each data packet's delay meets the requirements). The current method of monitoring the average delay of multiple data packets within a cycle cannot accurately determine whether the delay reliability of the service meets the transmission requirements of the service.

Although the QoS monitoring mechanism can determine the delay of a single data packet, in order to reduce the computing and storage burden of the access network equipment, the access network equipment usually only stores the average delay of the data packets reported within a period of time. This causes the access network equipment to be unable to accurately determine the delay reliability of the service.

In order to solve the problems existing in related technologies, the present disclosure provides a delay reliability determination method. The access network device obtains the delay of the data packets of the target service within the target time period, and determines the number of data packets as the first quantity. The access network equipment determines the target delay, and compares the delay of each data packet with the target delay. Data packets with a delay less than or equal to the target delay are recorded as non-timeout packets, and determine that they have not timed out. The second number of packets. The access network device determines the proportion of non-timeout data packets in the data packets of the target service based on the ratio of the second quantity and the first quantity. Since non-timed-out data packets are generally delay-reliable data packets, by determining the proportion of non-timed-out data packets, the delay reliability of the target service can be accurately determined.

As shown in Figure 5, a delay reliability determination method is provided in an embodiment of the present disclosure. This method can be specifically implemented through steps 501 to 503 as shown in Figure 5, which will be described in detail below.

Step 501: The access network device determines the first number of data packets of the target service transmitted within the target time period, and the delay of the data packets.

In a possible implementation manner, the above data packet is a data packet of a specific service. For example, the above data packet is a data packet of the URLLC service transmitted by the target service within the target time period.

Optionally, the access network equipment can determine the delay of each data packet through QoS monitoring.

Specifically, the access network equipment monitors each data packet of the target service within the statistical period and determines the delay of each data packet. The access network equipment counts the data packets of the target service within the statistical period and determines the target service data. The first quantity of the package.

It should be noted that the access network device can periodically count the data packets of the target service. In this case, the above target time period is the statistical period of the access network device.

It should be noted that the above-mentioned data packets of the target service transmitted within the target time period may be all data packets of the target service that are received by the access network device within the target time period, or may be received within the target time period. The data packets that meet the requirements among all the data packets of the target service collected by the network access device.

For example, when determining the uplink delay reliability, the data packets of the target service transmitted within the target time period may be the uplink data packets of the target service collected by the access network device within the target time period.

When determining the downlink delay reliability, the data packets of the target service transmitted within the target time period may be the downlink data packets of the target service collected by the access network device within the target time period.

In addition, the above-mentioned data packets of the target service transmitted within the target time period can be set according to actual needs in specific application scenarios, and will not be described again here.

Step 502: The access network device determines the second number of non-timed-out data packets in the data packet based on the delay of the data packet.

Among them, non-timed-out data packets are data packets whose delay is less than or equal to the target delay.

Specifically, the access network equipment determines the target delay and compares the delay of each data packet with the target delay. The access network equipment determines that data packets whose delay is less than or equal to the target delay are non-timed-out data packets. The access network device counts the non-timed-out data packets in the above-mentioned data packets and determines the second number of non-timed-out data packets in the data packets.

It should be pointed out that in the embodiment of the present disclosure, the above target delay value may be configured by the staff for the access network device, or determined by the access network device based on the delay configuration information, or by the core network device. It is indicated by the access network device, or determined by the access network device based on the relevant configuration after the core network device delivers relevant configuration information to the access network device. This disclosure does not limit this.

As an example, the target delay value in the embodiment of the present disclosure may be 10 ms.

Step 503: The access network device determines the delay reliability of the target service based on the ratio of the second quantity and the first quantity.

In a possible implementation manner, the access network device may determine the delay reliability of the target service based on the relationship between the ratio of the second quantity and the first quantity and the preset threshold.

In another possible implementation manner, the access network device can input the ratio of the above-mentioned second quantity and the first quantity into a preset formula to determine the delay reliability of the target service.

In another possible implementation, the access network device may also combine the above first quantity, the second quantity, the ratio of the second quantity and the first quantity, the delay of the data packet, the delay of the untimed data packet, the timeout At least one of the delays of the data packet (that is, the data packet with a delay greater than the target delay) is input into the trained neural network model to determine the delay reliability of the target service.

In addition, the access network device can also determine the delay reliability of the target service through other methods based on the above-mentioned first quantity and the second quantity, which is not limited in this disclosure.

It should be pointed out that the ratio between the above-mentioned second quantity and the first quantity can represent the proportion of non-timed-out data packets among the data packets transmitted by the target service within the target time period, and the non-timed-out data packets are data packets with reliable delay. Therefore, in the present disclosure, the delay reliability of the target service can be determined through the ratio of the second quantity and the first quantity.

The above solution at least brings the following beneficial effects: the access network equipment obtains the delay of the data packets of the target service within the target time period, and determines the number of data packets as the first number. The access network equipment determines the target delay and compares Describe the relationship between the delay of each data packet and the target delay, record the data packets whose delay is less than or equal to the target delay as non-timed-out data packets, and determine the second number of non-timed-out data packets. The access network device determines the proportion of non-timeout data packets in the data packets of the target service based on the ratio of the second quantity and the first quantity. Since non-timed-out data packets are delay-reliable data packets, by determining the proportion of non-timed-out data packets, the delay reliability of the target service can be accurately determined.

Above, the delay reliability determination method involved in the embodiments of the present disclosure has been described.

It should be pointed out that the access network device needs to first determine the target delay before determining the timeout packet. The method for determining the target delay for access network equipment is described in detail below.

In the embodiment of the present disclosure, the situations in which the access network device determines the target delay include the following situations 1 to 4. Cases 1 to 4 are respectively: case 1, the target delay is the delay determined by the access network device in response to the first operation; case 2, the target delay is the access network device based on the preconfigured first delay configuration information The determined delay; case 3, the target delay is the delay determined according to the first indication information sent by the core network device; case 4, the target delay is the delay determined according to the second indication information sent by the core network device.

The above-mentioned case 1 and case 4 are described in detail below respectively.

Case 1: The target delay is the delay determined by the access network device in response to the first operation.

The first operation is an operation input in a network management configuration system of the access network device for configuring the target delay.

For example, in response to a target delay configuration request operation received by the input device, the access network device displays a target delay configuration interface. Staff can manually enter the target delay value in the configuration interface. In response to the operation of configuring the target delay value on the configuration interface received by the input device, the access network device configures the target delay value.

Case 2: The target delay is the delay determined by the access network device based on the preconfigured first delay configuration information.

The above-mentioned first delay configuration information may be the target delay configured for the service when the staff configures the service. The first delay configuration information is used to configure the target delay.

For example, when the staff configures the service parameters of the service in the network management system, the target delay is configured as one of the service parameters. After the configuration is completed, the access network equipment determines the target delay based on the service parameters of the service.

Optionally, the above delay configuration information can be a specific target delay value, a correspondence between different types of services and different target delay values, or a calculation method for the target delay value. This document There are no public restrictions on this.

As an example, the first delay configuration information may be packet delay budget (packet delay budget, PDB) configuration information. The access network device can determine the target delay based on the delay value indicated by the packet delay budget configuration information and the corresponding calculation rules. For example, taking 5QI=82 of the target service as an example, according to the current relevant protocol regulations, when 5QI=82, the value of PDB is 10ms, and the transmission between the access network equipment and the core network equipment reserves CN The PDB is 1ms. At this time, the downlink target delay value on the wireless air interface side of the access network device is 9ms.

Case 3: The target delay is the delay determined based on the first indication information sent by the core network device.

The first indication information is used to indicate the value of the target delay.

In a possible implementation manner, the core network device sends first indication information to the access network device, where the first indication information is used to indicate the value of the target delay. After receiving the first indication information, the access network device determines the value of the target delay according to the first indication information.

Optionally, the first indication information may be carried in survival time signaling sent by the core network device to the access network device.

Case 4: The target delay is the delay determined based on the second indication information sent by the core network device.

The second indication information is used to indicate the second delay configuration information; the second delay configuration information is used to configure the target delay.

In a possible implementation manner, the core network device sends second indication information to the access network device, and the second indication information is used to indicate delay configuration information. After receiving the second indication information, the access network device determines the value of the target delay according to the delay configuration information in the second indication information.

It can be understood that the above situations 1 to 4 are only exemplary methods for determining the target delay by the access network device. During the specific implementation process, the access network device can also determine the target delay through other methods, which is not limited in this disclosure.

It should be pointed out that in the embodiments of the present disclosure, the access network device can determine different target delays for uplink transmission and downlink transmission respectively.

For example, the target delay may include: a first target delay and a second target delay. The first target delay is the delay corresponding to the uplink data packet; the second target delay is the delay corresponding to the downlink data packet.

When the target delay includes the first target delay, the data packet includes the uplink data packet; that is to say, for the uplink data packet, the access network device determines that the target delay is the first target delay corresponding to the uplink data packet. extension.

When the target delay includes the second target delay, the data packet includes the downlink data packet; that is to say, for the downlink data packet, the access network device determines that the target delay is the second target time corresponding to the downlink data packet. extension.

In this way, in uplink transmission and downlink transmission scenarios, the access network equipment sets different target delays, which can further improve the accuracy of determining the delay reliability of the target service.

In addition, access network equipment can set different target delays for services of different Public Land Mobile Network (PLMN) networks, different slices or different 5G QoS Identifiers (5QI). That is to say, the target delays corresponding to the services of different PLMN networks can be different. The target delays of services carried by different slices can be different, and the target delays of services carried by different 5QIs can also be different.

Specifically, the access network equipment can set corresponding target delays for services in different PLMN networks; and/or, the access network equipment can set corresponding target delays for services carried by different slices; and/or, Access network equipment can set corresponding target delays for different 5QI services. After the access network equipment collects the data packet, it determines the target delay of the data packet based on at least one of the 5QI, slicing and PLMN network of the data packet service.

In one example, the target delay includes: a third target delay, a fourth target delay and a fifth target delay.

Among them, the third target delay is the delay corresponding to the data packet of the target PLMN network; the fourth target delay is the delay corresponding to the data packet of the target slice; the fifth target delay is the delay corresponding to the data packet of the target 5QI service. .

When the target delay includes the third target delay, the data packet includes a data packet of the target PLMN network.

In the case where the target delay includes the fourth target delay, the data packet includes the data packet of the target slice.

When the target delay includes the fifth target delay, the data packet includes the data packet of the target 5QI service.

It should be pointed out that when the target delay is distinguished with PLMN, slice or 5QI as the granularity. Access network equipment can further differentiate based on PLMN, slice or 5QI granularity, combined with uplink and downlink transmission.

For example, the above-mentioned third target delay may include a first sub-target delay and a second sub-target delay; wherein the first sub-target delay is the delay corresponding to the uplink data packet of the target PLMN network; the second sub-target delay is Delay is the delay corresponding to the downlink data packet of the target PLMN network.

The above-mentioned fourth target delay may include a third sub-target delay and a fourth sub-target delay; wherein the above-mentioned third sub-target delay is the delay corresponding to the uplink data packet of the target slice; the fourth sub-target delay is The delay corresponding to the downlink data packet.

The above-mentioned fifth target delay may include a fifth sub-target delay and a sixth sub-target delay; wherein the above-mentioned fifth sub-target delay is the delay corresponding to the uplink data packet of the target 5QI; the sixth sub-target delay is The delay corresponding to the downlink data packet of target 5QI.

The above describes the method for the access network equipment to determine the target delay.

The following is a detailed description of the manner in which the access network device determines the delay reliability of the target service based on the ratio of the second quantity and the first quantity in the above step 503.

With reference to Figure 5, as shown in Figure 6, the above step 503 can be specifically implemented through the following steps 601 to 603.

Step 601: The access network device determines whether the ratio of the second quantity to the first quantity is greater than the first ratio.

The first ratio may be a preset ratio. For example, the specific value of the above first ratio can be set to 60%, 80%, 90%, 99%, 99.9%, 99.99%, 99.999%, etc., which will not be described again here.

For the convenience of illustration, the first ratio is generally set to 60% or 80% in this disclosure. During specific implementation, those skilled in the art can set the size of the first ratio according to actual needs. This disclosure does not do this. limited.

Step 602: If the ratio between the second quantity and the first quantity is greater than or equal to the first ratio, the access network device determines that the delay reliability of the target service meets the requirements.

It should be pointed out that when the ratio of the second quantity to the first quantity is greater than or equal to the first ratio, it means that the proportion of untimed data packets (that is, data packets with reliable delay) meets the needs of the target service. At this time, access The network equipment can determine that the overall delay reliability of the target service meets the requirements.

In one example, the above first ratio is 60%, the access network device obtains the delay of 100 data packets of the target service within the target time period, and the number of non-timeout data packets among the 100 data packets is 88. At this time, the access network device determines that the ratio of the second quantity to the first quantity is 88%, which is greater than 60%. The access network equipment determines that the delay reliability of the target service meets the requirements.

Step 603: If the ratio between the second quantity and the first quantity is less than the first ratio, the access network device determines that the delay reliability of the target service does not meet the requirements.

It should be pointed out that when the ratio of the second quantity to the first quantity is less than the first ratio, it means that the proportion of untimed data packets (that is, data packets with reliable delay) does not meet the needs of the target service. At this time, access The network equipment can determine that the overall delay reliability of the target service does not meet the requirements.

In one example, the above first ratio is 60%, the access network device obtains the delay of 100 data packets of the target service within the target time period, and the number of non-timeout data packets among the 100 data packets is 46. At this time, the access network device determines that the ratio of the second quantity to the first quantity is 46%, which is less than 60%. The access network equipment determines that the delay reliability of the target service does not meet the requirements.

The above solution at least brings the following beneficial effects: the access network equipment presets the first ratio, and then determines whether the number of non-timeout data packets with reliable delay is satisfied based on the relationship between the ratio of the second quantity and the first quantity and the first ratio. Business needs. In this way, the access network equipment can more directly and quickly determine the delay reliability of the target service.

Combined with Figure 6, as shown in Figure 7, after the above step 603, the access network device can specifically optimize the delay reliability of the target service through the following step 701.

Step 701: The access network device enables the target function.

Among them, the above target functions are used to optimize the delay reliability of the target service.

It should be pointed out that the delay reliability determination method provided by the present disclosure is explained above by taking the access network device to determine the delay reliability of the target service based on the ratio of the number of untimed data packets and the total data packets as an example. exist During the specific implementation process, the access network equipment can also determine the delay of the target service based on the ratio of the number of timed data packets (that is, data packets with a delay greater than the target delay, that is, data packets with unreliable delays) and the total data packets. Reliability, its specific implementation method is similar to the method, the difference is: in this process, the access network equipment can set a second ratio for the timeout packet, and it is determined when the ratio of the timeout packet to the total data packet is less than the second ratio The delay reliability of the target service meets the requirements; when the ratio of the timeout data packet to the total data packet is greater than or equal to the second ratio, it is determined that the delay reliability of the target service does not meet the requirements.

In a possible implementation, as shown in Figure 9, this embodiment of the present disclosure also provides a method for determining the delay reliability of a cell, which specifically includes:

Step 901: The access network device determines the third number of data packets transmitted by the target cell within the target time period and the delay of the data packets transmitted by the target cell.

Wherein, when the target delay is configured with 5QI as the granularity, the data packets transmitted by the target cell may be data packets of one or more services corresponding to 5QI transmitted by the target cell.

When the target delay is configured at the granularity of slices, the data packets transmitted by the target cell may be data packets of services corresponding to one or more slices transmitted by the target cell.

When the target delay is configured at the PLMN granularity, the data packets transmitted by the target cell may be data packets of services corresponding to one or more PLMNs transmitted by the target cell.

It should be pointed out that the implementation of step 901 is similar to the above-mentioned step 501, and will not be described again here.

Step 902: The access network device determines the fourth number of non-timed-out data packets in the data packets transmitted by the target cell based on the delay of the data packets transmitted by the target cell.

It should be pointed out that the implementation of step 902 is similar to the above-mentioned step 502. For the specific implementation of step 902, please refer to the records in the above-mentioned step 502 and possible implementations of step 502, which will not be described again here.

Step 903: The access network device determines the delay reliability of the target cell based on the ratio of the fourth quantity and the third quantity.

It should be pointed out that the implementation of step 903 is similar to the above-mentioned step 503. For the specific implementation of step 903, please refer to the records in the above-mentioned step 503 and possible implementations of step 503, which will not be described again here.

It can be understood that, when the delay reliability of the target cell does not meet the requirements, the access network device can also instruct the target cell to perform the above step 701 to improve the delay reliability of the target cell. This application does not limit this.
