cross reference

The present invention claims the priority of a Chinese patent application filed with the Chinese Patent Office, the application number is 201910944771.9, and the invention title is "Uplink Authorization Request Control Method, Device, Terminal, and Storage Medium" on September 30, 2019, and the entire content of the application Incorporated in the present invention by reference.

Technical field

The present invention relates to the field of communications, and in particular to a method, device, terminal and storage medium for controlling an uplink authorization request.

Background technique

Narrow Band Internet of Things (NB-IoT) is an emerging technology in the Internet of Things (IoT) field, which supports the cellular data connection of low-power devices in the wide area network. It is also called low-power wide area network. (Low Power Wide Area Network, LPWAN). NB-IoT supports efficient connection of devices with long standby time and high network connection requirements.

Since NB-IoT only supports a narrowband bandwidth of 200K, this represents a shortage of air interface resources. With the growth of the number of terminals on the existing network and the volume of business, the introduction of the NB-IoT multi-carrier function has been accompanied. In some NB-IoT terminals in a poor channel environment, when the NB-IoT cell business is busy, especially after the introduction of NB-IoT multi-carrier technology, it is easy to appear that the wireless connection status of the terminal and the NB-IoT cell is inconsistent, that is, under the base station. A radio link release (RRC Connection Release) is sent, but the terminal side does not receive it. The terminal side considers it to be in the connected state, and the base station side considers the terminal to be in an idle state, which leads to inconsistent states, which means that the terminal is out of synchronization.

When the terminal is in the out-of-synchronization state, when the terminal needs to send uplink data, because the terminal side thinks that it is in the connected state, it directly initiates the uplink service scheduling authorization (Service Request, SR) in the connected state. In the R13/R14 protocol, it is initiated for the terminal The SR needs to process the uplink authorization request from MSG1 to MSG3. The signaling overhead of this process is relatively large and the steps are complicated; however, since the base station side considers the terminal to be in an idle state, it will not respond to the SR message of the terminal. According to the relevant standard protocol, since the terminal side cannot receive the SR response, it will always initiate an SR request to the base station until the number of transmissions reaches the maximum number of repetitions N specified in the system message. According to the above analysis, it can be seen that the terminal repeatedly transmits N times SR will not necessarily receive a response from the base station, but it needs to process the uplink authorization request from MSG1 to MSG3 N times, resulting in wasting a lot of NB-IoT air interface bandwidth resources, aggravating air interface resource tension, and wasting terminal resources and batteries. Electricity; also reduces the efficiency of NB-IoT business processing.

Detailed ways

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the embodiments of the present invention in detail through specific implementations in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

Example one:

In related technologies, when a terminal in an out-of-synchronization state needs to initiate an SR, it can only stop when the number of times the SR is sent reaches the maximum number of repetitions N, which leads to a huge waste of resources and reduces the problem of NB-IoT service processing efficiency. ; In this embodiment, when the terminal sends an uplink service scheduling authorization request to the base station, it obtains the current performance parameters of the base station. According to the performance parameters, it is determined that the handover conditions are currently met and the response to the uplink service scheduling authorization request is not received. In an out-of-synchronization state, stop sending uplink service scheduling authorization requests to the base station, thereby avoiding repeating sending uplink service scheduling authorization requests to the base station that will not receive a correct response, improving the resource utilization of the base station and the terminal side, and NB-IoT Business processing efficiency.

For ease of understanding, this embodiment is described below with reference to the uplink authorization request control method on the terminal side shown in FIG. 1 as an example, which includes the following steps.

S101: Send an uplink service scheduling authorization request to the base station, and obtain the current performance parameters of the base station.

In this step, the terminal has established a normal wireless connection with the NB-IoT cell on the base station side before sending the uplink service scheduling authorization request to the base station. Therefore, in this step, when the terminal sends an uplink service scheduling authorization request to the base station, the terminal may actually be in a normal connection state, or may be in an out-of-synchronization state (that is, the terminal believes that it is in a normal connection state due to various factors). , And the base station considers it to be in an idle state).

In this embodiment, the terminal can directly initiate a connected uplink service scheduling authorization request to the base station when it needs to send uplink data; of course, the terminal can also be triggered by other conditions to initiate an uplink service scheduling authorization request to the base station. Flexible setting of application scenarios.

It should be understood that the uplink authorization request control method shown in FIG. 1 can be applied to, but not limited to, the narrowband IoT. When applied to the narrowband IoT, the terminal in FIG. 1 is an NB-IoT terminal, and the base station is an NB-IoT base station. Of course, the uplink authorization request control method shown in FIG. 1 can also be applied to other network scenarios, and the corresponding terminals and base stations are the terminals and base stations in the corresponding network scenarios.

It should be understood that in the above step S101, the terminal sends the uplink service scheduling authorization request to the base station, which may be any time before the maximum number of repeated transmissions N. In this embodiment, the terminal currently sends the uplink service scheduling authorization request to the base station for the nth time. Sending, it can be seen from the above analysis that the value of n may be any integer value from 1 to N. Therefore, in step S101, after the terminal currently sends an uplink service scheduling authorization request to the base station, it can record and update the current value of n, that is, how many times it is currently sending an uplink service scheduling authorization request to the base station, and can set the value of n The value is also used as part of the performance parameter.

In this embodiment, the acquired current performance parameter of the base station may be any parameter that can be used to evaluate whether the current set handover condition is satisfied.

S102: According to the acquired performance parameters, when it is determined that the handover condition is currently met and the base station has not received a response to the uplink service scheduling authorization request sent in S101, it is determined that the current is in an out-of-synchronization state, and the uplink service scheduling authorization request is stopped to the base station. .

In this embodiment, the terminal sends an uplink service scheduling authorization request to the base station and obtains the current performance parameters of the base station; when the terminal determines that the handover conditions are currently met according to the performance parameters, and does not receive a response to the uplink service scheduling authorization request, It is determined that it is currently in an out-of-synchronization state and stops sending uplink service scheduling authorization requests to the base station; there is no need to wait until the number of sending uplink service scheduling authorization requests reaches the maximum number of repetitions N, so the resources on the base station side and the terminal side can be improved Utilization rate, and business processing efficiency of NB-IoT.

In this embodiment, when the terminal determines that it is currently in an out-of-synchronization state, it may also include the terminal resending an access request to the base station to re-establish a connection with the base station as soon as possible, and then continue normal corresponding services, thereby improving service processing efficiency.

In this embodiment, when it is determined according to the acquired performance parameters that the handover conditions are not currently met, and the base station has not received a response to the uplink service scheduling authorization request sent in S101, and the current number of transmissions n is less than N, the terminal can continue Send an uplink service scheduling authorization request to the base station, and then go to the above S101, and continue to judge until a normal response from the base station is received, or the current number of transmissions n is equal to N.

In this step, the terminal may determine whether the handover condition is currently satisfied according to the performance parameters obtained from the base station. For example, in an example, the handover condition may include determining but not limited to at least one of the following based on the obtained performance parameters, then It is considered that the switching condition is satisfied.

According to the obtained performance parameters, it is determined that the current resource of the base station is short, the downlink channel quality is not currently hopped, and the current number n of continuously sending uplink service scheduling authorization requests to the base station is equal to the preset first handover frequency threshold N1.

According to the acquired performance parameters, it is determined that the current resources of the base station are not in short supply, the downlink channel quality is not currently hopped, and the current number of consecutively sending uplink service scheduling authorization requests to the base station n is equal to the preset second switching frequency threshold N2.

The quality of the downlink channel is currently hopping.

Wherein, the above-mentioned N1 is less than the maximum number of retransmissions of the uplink service scheduling authorization request N, and N2 is less than N1.

In this embodiment, it is determined that the current resource of the base station is in short supply, and it can be determined whether at least one of the uplink resource and the downlink resource of the base station is in short supply. For example, in some examples, it can be determined whether the uplink resources of the base station are in short supply, in other examples, it can be determined whether the downlink resources of the base station are in short supply, and in other examples, it can also be determined whether the uplink resources and downlink resources are in short supply; correspondingly It is possible to determine whether the uplink resources and/or downlink resources on the base station side are in short supply through any parameter that can reflect the resource situation of the base station side. For example, the current utilization of uplink bandwidth and/or downlink bandwidth can be obtained to determine whether the uplink resources and/or downlink resources on the base station side are in short supply; other performance parameters can also be obtained to determine whether the uplink resources and/or downlink resources on the base station side are in short supply. . For another example: in an example, in order to determine whether resources on the base station side are in short supply, obtaining performance parameters may include, but is not limited to: at least one of uplink scheduling response parameters and downlink scheduling response parameters.

Correspondingly, in this embodiment, the terminal may determine that the current resource of the base station is short when detecting at least one of the following.

When the performance parameter includes an uplink scheduling response parameter, the value of the uplink scheduling response parameter is greater than the value of the normal uplink scheduling response parameter.

When the performance parameter includes a downlink scheduling response parameter, the value of the downlink scheduling response parameter is greater than the value of the normal downlink scheduling response parameter.

In this embodiment, the value of the normal uplink scheduling response parameter and the value of the normal downlink scheduling response parameter can be set according to experience or based on detection when the terminal is not in the out-of-synchronization state, and the base station responds when the uplink scheduling and downlink scheduling normally respond to the terminal Value.

In some examples of this embodiment, it can be set as long as it is determined that any one of the uplink resources and downlink resources on the base station side is in short supply, then it is determined that the resources on the base station side are tight; it can also be set to only determine the uplink resources and downlink resources on the base station side. When all are in short supply, it is determined that the resources on the base station side are tight. Which method is used can be flexibly set according to requirements.

It should be understood that, in this embodiment, the terminal can obtain various parameters that can reflect the uplink scheduling response of the base station to determine whether the uplink resources on the base station side are in short supply. For example, when the performance parameter obtained by the terminal includes an uplink scheduling response parameter, the obtained uplink scheduling response parameter includes at least one of a first uplink scheduling response delay time and a second uplink scheduling response delay time.

The first uplink scheduling response delay time Delay0 includes: when the uplink service scheduling authorization request is sent for the current n times, the response phase Msg2 of the preamble access phase Msg1 is the average duration between the start position of the narrowband physical downlink control channel and the end position of Msg1; the second uplink The scheduling response delay time Delay1 includes: the average duration between the start position of the Msg2 narrowband physical downlink control channel and the start position of the Msg2 narrowband physical downlink shared channel when the uplink service scheduling authorization request is sent for the current n times.

In this embodiment, the terminal can also obtain various parameters that can reflect the downlink scheduling response of the base station to determine whether the downlink resources on the base station side are in short supply. For example, when the performance parameters acquired by the terminal include downlink scheduling response parameters, the acquired downlink scheduling response parameters include: downlink scheduling response delay time, and the downlink scheduling response delay time Delay2 includes: the uplink data when the uplink service scheduling authorization request is sent for the current n times The average duration between the start position of Msg3 in the request phase and the end position of the Msg2 narrowband physical downlink shared channel.

Correspondingly, it should be understood that the acquired performance parameters may include any various parameters that can evaluate the quality of the downlink channel, for example, may include the downlink channel quality indicator parameter; in this embodiment, when the downlink channel quality indicator parameter is detected When the difference between the value and the value of the normal downlink channel quality indicator parameter is greater than or equal to the preset difference threshold, it is determined that the downlink channel quality is currently hopping; the value of the normal downlink channel quality indicator parameter is the downlink channel quality under the normal communication environment Indicates the value of the parameter. And it should be understood that the specific value of the preset difference threshold can be flexibly set according to specific application scenarios. In an application scenario, the downlink channel quality indicator parameter may include, but is not limited to: the average downlink channel signal-to-noise ratio measured when the uplink service scheduling authorization request is sent for the current n times.

It can be seen that, compared with related technologies, the uplink authorization request control method provided in this embodiment achieves the effect of quickly correcting the out-of-synchronization state of the connection with the base station when the terminal is connected to the base station out of synchronization, and saves mouth space. Resources, improve the uplink data transmission efficiency when the connection with the base station is out of synchronization.

Embodiment two:

This embodiment provides an uplink authorization request control device. The uplink authorization request control device can be set in a terminal, as shown in FIG. 2, which includes the following modules.

The sending module 201 is configured to send an uplink service scheduling authorization request to the base station. For the sending process, refer to the above-mentioned embodiment, which will not be repeated here.

The obtaining module 202 is configured to obtain the current performance parameters of the base station. For the specific obtaining process, refer to the above-mentioned embodiment, which will not be repeated here.

The processing module 203 is configured to determine that when the handover condition is currently met and the base station's response to the uplink service scheduling authorization request is not received according to the performance parameters obtained by the obtaining module 202, it is determined that it is currently in an out-of-synchronization state and stops sending uplink services to the base station Scheduling authorization requests. For the specific processing process, refer to the above-mentioned embodiment, which will not be repeated here.

It should be understood that the functions of the sending module 201 described above in this embodiment can be implemented by, but not limited to, the radio frequency module of the terminal, and the functions of the acquisition module 202 and the processing module 203 can be implemented by, but not limited to, the processor of the terminal.

For ease of understanding, this embodiment will be described below in conjunction with an NB-IoT application scenario as an example.

In an NB-IoT application scenario, the NB-IoT terminal obtains the maximum number of SR attempts according to system messages, where the number of repetitions is inconsistent for different coverage levels. The NB-IoT base station can be configured with up to three coverage levels (CEL0, CEL1, CEL2), and the number of repetitions corresponding to each coverage level is (M0, M1, M2). The maximum number of SR attempts of the CEL0 terminal is M0+M1+M2, the maximum number of SR attempts of the CEL1 terminal is M1+M2, and the maximum number of SR attempts of the CEL2 terminal is M2. According to the 3gpp standard: if the SR of the CEL0 terminal tries M0 consecutively, it will be automatically adjusted to CEL1, after continuing to try M1 times, it will be adjusted to CEL2, and continue to try M2 times. The same is true for CEL1, so I won't repeat it here.

Based on the above application scenario, an exemplary uplink authorization request control method is shown in FIG. 3, which includes the following steps.

S301: The NB-IoT terminal (hereinafter referred to as the terminal) obtains the maximum number of repetitions N of the SR.

In this application scenario, it is assumed that the wireless connection with the base station is out of synchronization state due to wireless channel fluctuations or cross-carrier data transmission of the NB-IoT terminal. In the out-of-synchronization state, the terminal has uplink data to send, and the terminal triggers the SR in the connected state.

S302: The terminal has continuously sent the nth SR, and is performing n+1 SR.

S303: The SR sent by the terminal triggers Msg1, which triggers subsequent Msg2 and Msg3 scheduling by the base station.

S304: Obtain the scheduling data and data stream of the base station Msg2, and obtain the signal-to-noise ratio of the downlink channel.

S305: The continuous transmission count n obtained in S302, the duration of the start position of Msg2 NPDCCH and the end position of Msg1 obtained in S303 and S304, the n+1th time is recorded as X(n+1), the historical average of these n+1 times The value is Delay0. The duration between the start position of Msg2 NPDCCH and the start position of Msg2 NPDSCH, the n+1th time is denoted as Y(n+1), and the historical average value of these n+1 times is Delay1. The duration between the start position of Msg3 and the end position of Msg2 PDSCH, the n+1th time is denoted as Z(n+1), and the historical average of these n+1 times is Delay2. At the same time, the average measurement value of the downlink channel signal-to-noise ratio during the n+1 transmission process is obtained. When the response message of the n+1th SR is not received, it is determined whether to continue the n+2th SR initiation according to the above parameters.

For ease of understanding, the following example uses the terminal to continuously initiate SR, and the current resource shortage of the base station needs to determine the next idle state access. Please refer to Figure 4, which includes the following steps.

S401: The maximum number of attempts for the NB-IoT terminal to obtain the SR according to the system message N=10 times.

Assuming that the terminal is in an out-of-synchronization state, and the terminal has uplink data to send, the connected state SR is triggered.

S402: Assume that the terminal has continuously sent the 4th SR from CEL0.

S403: The connected state SR triggers Msg1, which triggers subsequent Msg2 and Msg3 scheduling of the base station.

S404: Obtain the scheduling data and data stream of the base station Msg2, and obtain the signal-to-noise ratio of the downlink channel.

S405: Calculate that Delay0 corresponding to the current fourth transmission of SR is 40, Delay1 is 32, and Delay2 is 32, and it is assumed that the signal-to-noise ratio of the downlink channel has jumped.

S406: In the case of the delay combination and the downlink channel signal-to-noise ratio hopping, when the SR response is not received, it is considered that it is in an out-of-synchronization state, the SR is stopped, and the re-access request is sent to the base station.

For ease of understanding, the following example assumes that the terminal continuously initiates SR, and the current resource of the base station is not in short supply and needs to decide to continue sending the SR next time. Please refer to FIG. 5, which includes the following steps.

S500: The maximum number of attempts for the NB-IoT terminal to obtain the SR according to the system message N=10 times.

S502: Assume that the NB-IoT terminal has continuously sent the fourth SR from CEL0.

S503: The connected state SR triggers Msg1, which triggers the subsequent Msg2 and Msg3 scheduling of the base station.

S504: Obtain the scheduling data and data stream of the base station Msg2, and obtain the signal-to-noise ratio of the downlink channel.

S505: Calculate that Delay0 corresponding to the current fourth transmission of SR is 15, Delay1 is 8, Delay2 is 16, and it is assumed that the signal-to-noise ratio of the downlink channel does not jump.

S506: In this Delay combination and the downlink channel signal-to-noise ratio has not hopped, when the SR response is not received, it is considered that it is still in the connected state, and the SR is continued to be initiated next time.

In order to facilitate understanding, the following example uses the case of cross-coverage levels and needs to decide to intervene in the idle state next time. Please refer to Figure 6 and include the following steps.

S601: The maximum number of attempts for the NB-IoT terminal to obtain the SR according to the system message is N=10.

S602: Assume that the NB-IoT terminal has initiated 10 times continuously from CEL0 and starts to initiate SR from CEL1.

S603: The connected state SR triggers Msg1, which triggers the subsequent Msg2 and Msg3 scheduling of the base station.

S604: Obtain the scheduling data and data stream of the base station Msg2, and obtain the signal-to-noise ratio of the downlink channel.

S605: Calculate that Delay0 corresponding to the current 11th SR transmission is 15, Delay1 is 10, and Delay2 is 20, and it is assumed that the signal-to-noise ratio of the downlink channel does not jump.

S606: In this Delay combination and the downlink channel signal-to-noise ratio does not change, the SR response is indeed not received. Although the scheduling interval has not changed significantly, it can be considered to be in an idle state (that is, the terminal is in an out-of-synchronization state). The terminal initiates access from the idle state next time.

For ease of understanding, when the signal-to-noise ratio of the downlink channel measured by the following example hops, the next time it is decided to access in the idle state for description, please refer to Figure 7, which includes the following steps.

S701: The NB-IoT terminal obtains the maximum number of repetitions of the SR according to the system message, where CEL0 is 10 times and CEL1 is 8 times.

S702: Assume that the NB-IoT terminal has continuously sent the third SR from CEL0.

S703: The connected state SR triggers Msg1, which triggers subsequent Msg2 and Msg3 scheduling of the base station.

S704: Obtain the scheduling data and data stream of the base station Msg2, and obtain the signal-to-noise ratio of the downlink channel.

S705: Calculate that Delay0 corresponding to the current third transmission of SR is 15, Delay1 is 16, Delay2 is 23, and it is assumed that the signal-to-noise ratio of the downlink channel has jumped.

S706: In the case of this Delay combination, the continuous measurement result shows that there is a jump in the measurement, and when the SR response is indeed not received, it is judged that it is in the idle state (that is, the terminal is in the out-of-synchronization state), and the next time it initiates access .

After the terminal equipped with the uplink authorization request control device provided in this implementation sends an SR request to the base station, it can flexibly determine that it is currently in an out-of-synchronization state and can stop sending SR to the base station, without having to wait until the number of sending SR requests reaches the maximum. It stops only when the number of repetitions is N, so the resource utilization of the base station side and the terminal side can be improved, and the service processing efficiency of NB-IoT can be improved.
