Description

Technical Field

[0001] The embodiments of the present invention relate to, but are not limited to, the field of communication technologies, and in particular to an access optimization method, a base station, a terminal, and a computer-readable storage medium. Background Art

[0002] During random access, the base station carries an RSRP (Reference Signal Receiving Power) threshold when sending an SSB (Synchronization Signal Block) signal. The user measures the SSB signal to obtain an RSRP measurement value, parses it to obtain the RSRP threshold, and then compares the RSRP measurement value with the RSRP threshold. If the RSRP measurement value is less than the RSRP threshold, the user selects the four-step random access mode. Otherwise, the user selects the two-step random access mode. The base station then configures the corresponding resources for both random access modes. If the number of users of a certain random access mode is too large, the probability of collision increases, the probability of system access failure increases, and resource utilization decreases.

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] It should be noted that although the device schematics illustrate functional module divisions and the flowcharts illustrate logical sequences, in certain circumstances, the steps shown or described may be performed in a sequence that differs from the module divisions in the device or the sequence in the flowcharts. The terms "first," "second," and the like in the specification, claims, or accompanying drawings are used to distinguish similar items and are not necessarily used to describe a specific sequence or precedence.

[0045] The present invention provides an access optimization method, a base station, a terminal, and a computer-readable storage medium. The access optimization method includes: the base station sends an SSB signal carrying an RSRP threshold to the terminal, the terminal then measures the SSB signal to obtain an RSRP measurement value and accesses the base station based on the RSRP measurement value and the RSRP threshold, the base station then obtains an access event parameter for the terminal to access the base station, and adjusts the RSRP threshold based on the access event parameter and a preset parameter to obtain an adjusted RSRP threshold, and finally the base station sends an SSB signal carrying the adjusted RSRP threshold to the terminal, so that the terminal can select a random access mode for accessing the base station based on the adjusted RSRP threshold. Therefore, the base station can adjust the RSRP threshold based on the actual access event parameter and preset parameter of the terminal. By adjusting the RSRP threshold, the number of access terminals and resource allocation for different random access modes can be controlled, thereby improving the terminal access success rate and resource utilization efficiency.

[0046] The embodiments of the present invention are further described below with reference to the accompanying drawings.

[0047] like Figure 1 As shown, Figure 1 FIG is a schematic diagram of a system architecture platform for executing an access optimization method provided by an embodiment of the present invention. Figure 1In the example of , the system architecture platform includes a base station 100 and a terminal 200, wherein the base station 100 is provided with a first processor 110 and a first memory 120, and the terminal 200 is provided with a second processor 210 and a second memory 220, wherein the first processor 110 and the first memory 120 can be connected through a bus or other means, and the second processor 210 and the second memory 220 can be connected through a bus or other means, Figure 1 The bus connection is taken as an example.

[0048] The first memory 120 and the second memory 220 are used as a non-transient computer-readable storage medium for storing non-transient software programs and non-transient computer executable programs. In addition, the first memory 120 and the second memory 220 may include high-speed random access memory, and may also include non-transient memory, such as at least one disk storage device, flash memory device, or other non-transient solid-state storage device. In some embodiments, the first memory 120 may optionally include a memory remotely arranged relative to the first processor 110, and the second memory 220 may optionally include a memory remotely arranged relative to the second processor 210, and these remote memories may be connected to the system architecture platform via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0049] Those skilled in the art will appreciate that the system architecture platform can be applied to 3G communication network systems, LTE communication network systems, 5G communication network systems, and subsequently evolved mobile communication network systems, and this embodiment does not specifically limit this.

[0050] It will be understood by those skilled in the art that Figure 1 The system architecture platform shown in the figure does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0051] exist Figure 1 In the system architecture platform shown, the first processor 110 can call the access optimization program stored in the first memory 120, or the second processor 210 can call the access optimization program stored in the second memory 220, thereby executing the access optimization method.

[0052] Based on the above system architecture platform, various embodiments of the access optimization method of the present invention are proposed below.

[0053] like Figure 2 As shown, Figure 2 This is a flowchart of an access optimization method provided by an embodiment of the present invention, which includes but is not limited to step S100, step S200, step S300 and step S400.

[0054] Step S100: Send an SSB signal carrying an RSRP threshold to the terminal.

[0055] In one embodiment, during the random access process, the base station carries an RSRP threshold when sending an SSB signal. The RSRP threshold can be used as a basis for the terminal to select a random access mode in subsequent steps.

[0056] Step S200: Acquire access event parameters for a terminal accessing a base station based on an RSRP threshold.

[0057] In one embodiment, when the terminal receives an SSB signal sent by the base station, the terminal will measure the SSB signal to obtain an RSRP measurement value. At the same time, the terminal will parse the SSB signal to obtain the RSRP threshold carried in the SSB signal. The terminal will then select a random access mode corresponding to the comparison result based on the comparison result between the RSRP measurement value and the RSRP threshold to access the base station. Finally, the base station can statistically obtain the access event parameters of the terminal accessing the base station based on the access situation of the terminal.

[0058] It should be noted that in the actual random access process, when the RSRP measurement value is greater than or equal to the RSRP threshold, the terminal will select the two-step random access mode to access the base station; when the RSRP measurement value is less than the RSRP threshold, the terminal will select the four-step random access mode to access the base station.

[0059] It is worth noting that the above-mentioned access event parameters may include but are not limited to at least one of the number of access failure events, the ratio of the number of access failure events in the same random access mode to the total number of access events, and the ratio of the number of access failure events to the number of access success events in the same random access mode.

[0060] Step S300: Adjust the RSRP threshold according to the access event parameters and the preset parameters.

[0061] In one embodiment, after the base station obtains the access event parameter of the terminal accessing the base station, it compares the access event parameter with the preset parameter and adjusts the RSRP threshold according to the numerical comparison result of the two parameters to obtain the adjusted RSRP threshold.

[0062] It is understandable that the above-mentioned preset parameters may be preset in the base station, or may be obtained by the base station through other means.

[0063] Step S400: Send an SSB signal carrying the adjusted RSRP threshold to the terminal, so that the terminal selects a random access mode of accessing the base station according to the adjusted RSRP threshold.

[0064] In one embodiment, after the base station obtains the adjusted RSRP threshold, if the base station needs to send an SSB signal subsequently, the RSRP threshold carried in the subsequently sent SSB signal will be updated to the adjusted RSRP threshold, so that the terminal will select an appropriate random access mode to access the base station according to the adjusted RSRP threshold.

[0065] In one embodiment, since the access optimization method uses the above-mentioned steps S100, S200, S300 and S400, the base station can adjust the RSRP threshold according to the actual access event parameters and preset parameters of the terminal. By adjusting the RSRP threshold, the number of access terminals in different random access modes and the resource allocation situation can be controlled, thereby improving the terminal access success rate and resource utilization efficiency.

[0066] It should be noted that the above-mentioned two-step random access mode can be reflected as follows: the terminal sends MsgA (Type A message) to the base station according to the SSB signal, where MsgA includes a random access preamble and CSI (Channel State Information), thereby initiating a contention access request and reporting the CSI; then after receiving MsgA, the base station sends MsgB (Type B message) to the terminal, where MsgB includes RAR (Random Access Response) and a contention resolution message, thereby responding to the contention access request initiated by the terminal and indicating a contention resolution solution based on the CSI.

[0067] Secondly, regarding the above-mentioned four-step random access mode, it can be reflected as follows: the terminal sends Msg1 (first message) to the base station, Msg1 includes a random access preamble, which is used to initiate a contention access request to the base station, and there is a contention relationship between terminals with consistent random access preambles; after the base station receives Msg1, it sends Msg2 (second message) to the terminal, Msg2 is RAR, which is used to respond to the contention access request initiated by the terminal; then the terminal sends Msg3 (third message) to the base station, which is used to report CSI according to the indication information of the base station, wherein the indication information can be RAR or SSB signal; finally, the base station sends Msg4 (fourth message) to the terminal, Msg4 includes a contention resolution message, indicating the contention solution made by the base station based on the CSI.

[0068] In addition, it is worth noting that the aforementioned access failure event refers to the event that the terminal cannot access the base station, and the aforementioned access success event refers to the event that the terminal successfully accesses the base station. The access failure event can be defined by the base station according to specific design.

[0069] It is understandable that the access optimization method of the embodiment of the present invention is implemented, including but not limited to, on devices and chips such as DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array) and ASIC (Application Specific Integrated Circuit).

[0070] In addition, refer to Figures 3 to 5 , Figures 3 to 5 This is a flowchart of the access optimization method provided by three other embodiments of the present invention. The above step S200 includes but is not limited to the following three situations.

[0071] In the first case, refer to Figure 3 , Figure 3 This is a flowchart of an access optimization method provided by another embodiment of the present invention, regarding the above-mentioned step S200, including but not limited to step S510.

[0072] Step S510: Acquire access event parameters for a terminal accessing a base station through a two-step random access mode based on an RSRP threshold.

[0073] In one embodiment, multiple terminals will select the two-step random access mode or the four-step random access mode to access the base station based on the comparison result of the RSRP measurement value and the RSRP threshold. Therefore, the base station in the embodiment of the present invention can choose to count the access status of the terminal to the base station through the two-step random access mode, so as to obtain the access event parameters of the terminal accessing the base station in the two-step random access mode.

[0074] In the second case, refer to Figure 4 , Figure 4 This is a flowchart of an access optimization method provided by another embodiment of the present invention, regarding the above-mentioned step S200, including but not limited to step S520.

[0075] Step S520: Acquire access event parameters for the terminal to access the base station through a four-step random access mode based on the RSRP threshold.

[0076] In one embodiment, multiple terminals will select the two-step random access mode or the four-step random access mode to access the base station based on the comparison result of the RSRP measurement value and the RSRP threshold. Therefore, the base station in the embodiment of the present invention can choose to count the access status of the terminal to the base station through the four-step random access mode, so as to obtain the access event parameters of the terminal accessing the base station in the four-step random access mode.

[0077] The third case, refer to Figure 5 , Figure 5 This is a flowchart of an access optimization method provided by another embodiment of the present invention, regarding the above-mentioned step S200, including but not limited to step S530.

[0078] Step S530: Acquire access event parameters for a terminal to access a base station through a two-step random access mode based on an RSRP threshold and access event parameters for a terminal to access a base station through a four-step random access mode based on an RSRP threshold.

[0079] In one embodiment, multiple terminals will select the two-step random access mode or the four-step random access mode to access the base station based on the comparison result of the RSRP measurement value and the RSRP threshold. Therefore, the base station in the embodiment of the present invention can separately count the access status of the terminal accessing the base station through the two-step random access mode and the access status of the terminal accessing the base station through the four-step random access mode, so as to obtain the access event parameters of the terminal accessing the base station in the two-step random access mode and the four-step random access mode, respectively.

[0080] In addition, refer to Figure 6 , Figure 6 This is a flowchart of an access optimization method provided by another embodiment of the present invention. In one embodiment, the above-mentioned step S200 includes but is not limited to step S600.

[0081] Step S600: Acquire access event parameters of a terminal accessing a base station based on an RSRP threshold within a preset time interval.

[0082] In one embodiment, after the terminal selects a random access mode to access the base station based on the comparison result of the RSRP measurement value and the RSRP threshold, the base station can collect statistics on the access status of the terminal within a preset time interval, thereby obtaining access event parameters of the terminal accessing the base station within the preset time interval.

[0083] It is worth noting that if the preset time interval is exceeded, the access event parameter is reset to zero and statistics are re-performed within a new preset time interval.

[0084] In addition, refer to Figure 7 , Figure 7 This is a flowchart of an access optimization method provided by another embodiment of the present invention. In one embodiment, the preset parameters include a first parameter and a second parameter, and the first parameter is smaller than the second parameter; regarding the above-mentioned step S300, it includes but is not limited to step S700.

[0085] Step S700: Adjust the RSRP threshold according to the access event parameter, the first parameter, and the second parameter.

[0086] In one embodiment, the preset parameters include a first parameter and a second parameter. Therefore, the embodiment of the present invention can divide the first parameter and the second parameter into three intervals, namely, an interval in which the parameter value is less than the first parameter, an interval in which the parameter value is greater than or equal to the first parameter and less than the second parameter, and an interval in which the parameter value is greater than the second parameter. Then, the embodiment of the present invention can compare the access event parameter with the first parameter and the second parameter, and perform corresponding adjustment operations on the RSRP threshold according to the interval in which the access event parameter falls.

[0087] In addition, refer to Figures 8 to 10 , Figures 8 to 10 This is a flowchart of the access optimization method provided by the other three embodiments of the present invention. When the access event parameter is an access event parameter for the terminal to access the base station through a two-step random access mode based on the RSRP threshold, then the above-mentioned step S700 includes but is not limited to the following three situations.

[0088] In the first case, refer to Figure 8 , Figure 8 This is a flowchart of an access optimization method provided by another embodiment of the present invention, regarding the above-mentioned step S700, including but not limited to step S810.

[0089] Step S810: When the access event parameter is less than the first parameter, lower the RSRP threshold.

[0090] In one embodiment, after the base station obtains the access event parameter of the terminal accessing the base station through the two-step random access mode, and the access event parameter is the number of access failure events in the two-step random access mode, the ratio of the number of access failure events to the total number of access events, or the ratio of the number of access failure events to the number of access success events, if the access event parameter is less than the first parameter, it indicates that under the RSRP threshold, the terminal can easily access the base station through the two-step random access mode, and the access success rate is high, but the number of terminals accessing the base station through the two-step random access mode may be relatively small. Therefore, in order to enable more terminals to access the base station through the two-step random access mode, the embodiment of the present invention can appropriately lower the RSRP threshold while keeping the success rate from decreasing too much.

[0091] In the second case, refer to Figure 9 , Figure 9 This is a flowchart of an access optimization method provided by another embodiment of the present invention, regarding the above-mentioned step S700, including but not limited to step S820.

[0092] Step S820: When the access event parameter is greater than or equal to the first parameter and less than the second parameter, the RSRP threshold is kept unchanged.

[0093] In one embodiment, after the base station obtains the access event parameter of the terminal accessing the base station through the two-step random access mode, and the access event parameter is the number of access failure events in the two-step random access mode, the ratio of the number of access failure events to the total number of access events, or the ratio of the number of access failure events to the number of access success events, if the access event parameter is greater than or equal to the first parameter and less than the second parameter, it indicates that under the RSRP threshold, the access success rate and the number of access terminals of the terminal accessing the base station through the two-step random access mode are balanced. Therefore, in this case, the embodiment of the present invention will keep the RSRP threshold unchanged.

[0094] The third case, refer to Figure 10 , Figure 10 This is a flowchart of an access optimization method provided by another embodiment of the present invention, regarding the above-mentioned step S700, including but not limited to step S830.

[0095] Step S830: When the access event parameter is greater than or equal to the second parameter, the RSRP threshold is increased.

[0096] In one embodiment, after the base station obtains the access event parameter of the terminal accessing the base station through the two-step random access mode, and the access event parameter is the number of access failure events in the two-step random access mode, the ratio of the number of access failure events to the total number of access events, or the ratio of the number of access failure events to the number of access success events, if the access event parameter is greater than or equal to the second parameter, it indicates that under the RSRP threshold, it is difficult for the terminal to access the base station through the two-step random access mode, and the access success rate is low. Therefore, in order to improve the access success rate, the embodiment of the present invention can appropriately increase the RSRP threshold.

[0097] In addition, refer to Figures 11 to 13 , Figures 11 to 13 This is a flowchart of the access optimization method provided by the other three embodiments of the present invention. When the access event parameter is an access event parameter for the terminal to access the base station through a four-step random access mode based on the RSRP threshold, then the above-mentioned step S700 includes but is not limited to the following three situations.

[0098] In the first case, refer to Figure 11 , Figure 11 This is a flowchart of an access optimization method provided by another embodiment of the present invention, regarding the above-mentioned step S700, including but not limited to step S910.

[0099] Step S910: When the access event parameter is less than the first parameter, the RSRP threshold is increased.

[0100] In one embodiment, after the base station obtains the access event parameter of the terminal accessing the base station through the four-step random access mode, and the access event parameter is the number of access failure events in the four-step random access mode, the ratio of the number of access failure events to the total number of access events, or the ratio of the number of access failure events to the number of access success events, if the access event parameter is less than the first parameter, it indicates that under the RSRP threshold, the terminal can easily access the base station through the four-step random access mode, and the access success rate is high, but the number of access terminals accessing the base station through the four-step random access mode may be relatively small. Therefore, in order to enable more terminals to access the base station through the four-step random access mode, the embodiment of the present invention can appropriately increase the RSRP threshold while keeping the success rate from decreasing too much.

[0101] In the second case, refer to Figure 12 , Figure 12 This is a flowchart of an access optimization method provided by another embodiment of the present invention, regarding the above-mentioned step S700, including but not limited to step S920.

[0102] Step S920: When the access event parameter is greater than or equal to the first parameter and less than the second parameter, the RSRP threshold is kept unchanged.

[0103] In one embodiment, after the base station obtains the access event parameter of the terminal accessing the base station through the four-step random access mode, and the access event parameter is the number of access failure events in the four-step random access mode, the ratio of the number of access failure events to the total number of access events, or the ratio of the number of access failure events to the number of access success events, if the access event parameter is greater than or equal to the first parameter and less than the second parameter, it indicates that under the RSRP threshold, the access success rate and the number of access terminals of the terminal accessing the base station through the four-step random access mode are balanced. Therefore, in this case, the embodiment of the present invention will keep the RSRP threshold unchanged.

[0104] The third case, refer to Figure 13 , Figure 13 This is a flowchart of an access optimization method provided by another embodiment of the present invention, regarding the above-mentioned step S700, including but not limited to step S930.

[0105] Step S930: When the access event parameter is greater than or equal to the second parameter, the RSRP threshold is lowered.

[0106] In one embodiment, after the base station obtains the access event parameter of the terminal accessing the base station through the four-step random access mode, and the access event parameter is the number of access failure events in the four-step random access mode, the ratio of the number of access failure events to the total number of access events, or the ratio of the number of access failure events to the number of access success events, if the access event parameter is greater than or equal to the second parameter, it indicates that under the RSRP threshold, it is difficult for the terminal to access the base station through the four-step random access mode, and the access success rate is low. Therefore, in order to improve the access success rate, the embodiment of the present invention can appropriately lower the RSRP threshold.

[0107] In addition, refer to Figure 14 , Figure 14 This is a flowchart of an access optimization method provided by another embodiment of the present invention. In one embodiment, the adjustment of the RSRP threshold in the above step S300 includes but is not limited to step S1000.

[0108] Step S1000: Adjust the RSRP threshold so that the adjusted RSRP threshold is between a preset lower limit and a preset upper limit; wherein the preset lower limit is smaller than the preset upper limit.

[0109] In one embodiment, if the base station adjusts the RSRP threshold too much, the RSRP threshold may be too high or too low, thereby affecting terminal access. Therefore, to ensure that the adjusted RSRP threshold does not appear too high or too low, this embodiment of the present invention sets a preset lower limit and a preset upper limit. When adjusting the RSRP threshold, the base station ensures that the adjusted RSRP threshold is between the preset lower limit and the preset upper limit.

[0110] In addition, refer to Figure 15 , Figure 15 This is a flowchart of an access optimization method provided by another embodiment of the present invention. In one embodiment, the adjustment of the RSRP threshold in the above step S300 includes but is not limited to step S1100.

[0111] Step S1100: Adjust the RSRP threshold according to a preset step size.

[0112] In one embodiment, the base station sets a preset step size for adjusting the RSRP threshold. Each time the base station needs to adjust the RSRP threshold, the RSRP threshold is gradually adjusted according to the preset step size. This embodiment of the present invention sets an appropriate preset step size to avoid excessive adjustments to the RSRP threshold each time.

[0113] In addition, refer to Figure 16 , Figure 161 is a specific flow chart of an access optimization method provided by another embodiment of the present invention. In one embodiment, the access optimization method includes but is not limited to step S1210, step S1220, step C1310, step S1230, step C1320, step S1240 and step S1250.

[0115] Step S1220: The base station updates statistics of the number of access failures using the two-step random access mode within a preset time interval, and sets a first parameter and a second parameter, wherein the first parameter is smaller than the second parameter;

[0116] Step C1310, determining whether the number of access failures is less than the first parameter, if so, executing step S1230, otherwise executing step C1320;

[0117] Step S1230: The base station lowers the RSRP threshold according to a preset step size, and does not fall below a preset lower limit, and updates it in a subsequently transmitted SSB signal;

[0119] Step S1240: The base station maintains the current RSRP threshold unchanged;

[0120] In step S1250, the base station increases the RSRP threshold according to a preset step size, which will not exceed a preset upper limit, and updates it in the subsequently sent SSB signal.

[0121] In one embodiment, specifically, when the base station sends an SSB signal, it also carries an RSRP threshold ξ and sets the threshold range, with a preset lower limit value ξ min and the preset upper limit ξ max , and a preset step size Δξ. Then, the base station ηThe internal statistics update uses the number of access failures η of the two-step random access mode, and sets two thresholds as the first parameter η1 and the second parameter η2, with 0<η1<η2. The initial value of the number of failures is zero. If it exceeds the preset time interval, the number is reset to zero, and the number of counts is re-performed within the new preset time interval. The access failure event can be defined as: the base station successfully detects the MsgA PRACH (Physical Random Access Channel) signal sent by the terminal, but fails to parse the MsgA PUSCH signal sent by the terminal. Finally, the base station finds out through comparison that η<η1, then reduces the RSRP threshold ξ=ξ-Δξ according to the preset step size, and must ensure that ξ≥ξ min , and updates the RSRP threshold in the subsequent SSB signals sent.

Then, the base station η Internal statistics update the number of access failures η using the two-step random access mode. Two thresholds are set: a first parameter η1 and a second parameter η2, with 0 < η1 < η2. The number of failures is initially zero. If it exceeds a preset time interval, the number is reset to zero and the number count is recalculated within the next preset time interval. An access failure event can be defined as the base station successfully detecting the MsgA PRACH signal sent by the terminal but failing to parse the MsgA PUSCH signal sent by the terminal. Finally, if the base station compares and determines that η1 ≤ η < η2, it maintains the current RSRP threshold ξ.
