Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communication technology, and in particular to an access control method, apparatus, device and storage medium for a 5G lightweight terminal based on electric power services. Background Art

[0002] When a terminal (such as user equipment) communicates with a base station, no matter what service is initiated, a random access process must be initiated first to establish a radio resource control connection between the terminal and the base station, thereby enabling data interaction between the terminal and the base station.

[0003] However, in the random access process of the existing technology, terminals carrying important business data and terminals carrying ordinary business data have the same access probability, which may cause the important business data to face higher data transmission delays, thereby affecting the normal operation of key services.

[0004] Therefore, it is urgent to propose a new method to solve the above problems. Summary of the Invention

[0005] The present invention provides an access control method, device, equipment and storage medium for 5G lightweight terminals based on electric power services, which can improve the access probability of terminals carrying important business data.

[0006] In a first aspect, an embodiment of the present invention provides an access control method for a 5G lightweight terminal based on electric power services, including:

[0007] Broadcasting access resource configuration information; the access resource configuration information includes access configuration information of the monitoring channel and access configuration information of each candidate data transmission channel, so that each terminal sends access request information to the base station through the monitoring channel according to the access configuration information of the monitoring channel, and each terminal selects a corresponding candidate data transmission channel according to the access configuration information of each candidate data transmission channel to send the access request information to the base station;

[0008] determining the number of important terminals currently attempting to access based on the access request information received through the monitoring channel, and sending the access request information to the base station through the monitoring channel when the importance of data of each terminal exceeds a preset importance;

[0009] When the number of important terminals currently attempting to access exceeds a preset number, access suspension notification information is broadcast to notify non-important terminals to suspend access. The non-important terminals are terminals whose data importance does not exceed the preset importance.

[0010] The technical solution of the present invention is to broadcast access resource configuration information; the access resource configuration information includes access configuration information of the monitoring channel and access configuration information of each candidate data transmission channel, so that each terminal sends access request information to the base station through the monitoring channel according to the access configuration information of the monitoring channel, and each terminal selects the corresponding candidate data transmission channel according to the access configuration information of each candidate data transmission channel to send access request information to the base station; the number of important terminals currently attempting access is determined based on the access request information received on the monitoring channel, and each terminal sends access request information to the base station through the monitoring channel when its own data importance exceeds a preset importance; when the number of important terminals currently attempting access exceeds a preset number, broadcast access suspension notification information to notify non-important terminals to suspend access, where non-important terminals are terminals whose own data importance does not exceed the preset importance. The above technical solution first broadcasts access resource configuration information, so that each terminal sends access request information to the base station through the monitoring channel according to the access configuration information of the monitoring channel, and each terminal selects the corresponding candidate data transmission channel according to the access configuration information of each candidate data transmission channel to send access request information to the base station, thereby ensuring that each terminal can communicate with the base station correctly and efficiently. Then, the number of important terminals currently attempting to access is determined based on the access request information received on the monitoring channel, providing a data basis for determining whether to broadcast the access suspension notification information. Then, it is determined whether the number of important terminals currently attempting to access exceeds the preset number. If not, the access suspension notification information is not broadcast. If exceeded, the access suspension notification information is broadcast to notify non-important terminals to suspend access, thereby increasing the access probability of important terminals and avoiding affecting the normal operation of critical services. Therefore, the present invention can solve the problem that in the random access process of the prior art, terminals carrying important business data and terminals carrying ordinary business data have the same access probability, which may cause important business data to face higher data transmission delays, thereby affecting the normal operation of critical services.

[0036] Figure 1 This is a flow chart of a method for access control of a 5G lightweight terminal based on electric power services provided by an embodiment of the present invention. This embodiment is applicable to the case where a random access process is initiated when a terminal communicates with a base station. The method can be executed by an access control device for a 5G lightweight terminal based on electric power services provided by the present invention. The device can be implemented in software and / or hardware. Specifically, the device can be integrated into an electronic device. Exemplarily, the electronic device can be a computer or a server. Figure 1 The access control method for 5G lightweight terminals based on electric power services in this embodiment may specifically include the following steps:

[0037] Step 110: Broadcast access resource configuration information so that each terminal sends access request information to the base station through the monitoring channel according to the access configuration information of the monitoring channel, and enables each terminal to select the corresponding candidate data transmission channel according to the access configuration information of each candidate data transmission channel to send access request information to the base station.

[0038] Specifically, access resource configuration information refers to information broadcast by a base station to each terminal, informing the terminal how to access the network. Access resource configuration information includes access configuration information for monitoring channels and access configuration information for candidate data transmission channels. A monitoring channel is a channel used by important terminals to send access requests to a base station and is used to identify important terminals currently attempting access. Access configuration information for monitoring channels specifies the rules that a terminal must follow when sending access requests via the monitoring channel, such as the transmission conditions, frequency, power, and time slot. Candidate data transmission channels are optional channels that a terminal can use to send access requests to a base station. Access configuration information for candidate data transmission channels specifies the rules that a terminal must follow when sending access requests via candidate data transmission channels. These rules determine whether to select a channel and how to use it to send access requests. Access request information refers to information sent by a terminal to a base station requesting access to the network covered by the base station. A terminal refers to a device that communicates with a network and can be, for example, a lightweight terminal, mobile phone, tablet, or IoT device.

[0039] In a specific implementation, access resource configuration information (including access configuration information for the monitoring channel and access configuration information for each candidate data transmission channel) can be determined based on actual conditions or needs, and then the access resource configuration information can be sent to all terminals within its coverage area using a broadcast channel (such as a physical broadcast channel). Then, for each terminal, after receiving the access resource configuration information, it will first check whether it meets the conditions for sending an access request through the monitoring channel (for example, only terminals whose data importance exceeds a preset importance threshold can use the monitoring channel to send an access request). If the access conditions for the monitoring channel are met, the access request information is prepared according to the access rules (such as frequency, power, and time slot, etc.) in the access configuration information, and then the access request information is sent to the base station through the monitoring channel. At the same time, after receiving the access resource configuration information, the terminal selects a suitable candidate data transmission channel based on the access configuration information of the candidate data transmission channel (such as channel priority, bandwidth limit, and transmission delay requirements) and its own needs (such as the need for a channel with large bandwidth). Then, based on the access configuration information of the selected candidate data transmission channel, the terminal sends the access request information to the base station through the selected candidate data transmission channel.

[0040] In this embodiment, access resource configuration information is broadcasted to ensure that each terminal can communicate with the base station correctly and efficiently.

[0041] Step 120: Determine the number of important terminals currently attempting access based on the access request information received through the monitoring channel.

[0042] Specifically, in this embodiment, each terminal transmits an access request to the base station via a monitoring channel when its data importance exceeds a preset importance. Data importance is a metric used to measure the importance of the data transmitted by a terminal. The preset importance is a threshold value pre-set based on actual conditions or needs, which is used to determine whether a terminal should transmit an access request to the base station via a monitoring channel. Important terminals are terminals whose data importance exceeds the preset importance.

[0043] In a specific implementation, after broadcasting the access resource configuration information, it should be noted that each terminal will send access request information to the base station through the monitoring channel only when the importance of its own data exceeds the preset importance. Based on this, the number of access request information currently received by the monitoring channel within the preset time period can be determined as the number of important terminals currently attempting access. Specifically, a counter can be used to count the number of access request information currently received by the monitoring channel within the preset time period, thereby obtaining the number of important terminals currently attempting access, and the counter will be set to 0 the next time it is used. Among them, the preset time period is a time period set in advance according to actual conditions or needs, which is used to help determine the number of important terminals currently attempting access. For example, the preset time period can be five seconds after the access resource configuration information is broadcast.

[0044] In this embodiment, the number of important terminals currently attempting access is determined based on the access request information received on the monitoring channel, which provides a data basis for subsequently determining whether to broadcast access suspension notification information.

[0045] Step 130: Determine whether the number of important terminals currently attempting to access exceeds a preset number.

[0046] If it exceeds, step 140 is executed; if it does not exceed, step 150 is executed.

[0047] Specifically, the preset number refers to a number threshold set in advance according to actual conditions or needs, and is used to determine whether the number of important terminals currently attempting to access exceeds a range that can be immediately processed by the base station.

[0048] In a specific implementation, after obtaining the number of important terminals currently attempting to access, it is determined whether the number of important terminals currently attempting to access exceeds the preset number. If it exceeds, it means that the access demand of important terminals in the current network is large, which has caused great pressure on network resources. If all terminals continue to be allowed to access, it may cause the access service quality of important terminals to decline (such as an increased probability of access failure, high data transmission delay, etc.). At this time, it is necessary to broadcast a suspended access notification message to notify non-important terminals to suspend access. If it does not exceed, it means that the current network load is within the normal range, and there is no need to restrict the access of non-important terminals. Non-important terminals can try to access the network according to normal access procedures and rules. At this time, there is no need to broadcast a suspended access notification message.

[0049] Step 140: Broadcast access suspension notification information to notify non-important terminals to suspend access.

[0050] Specifically, a non-important terminal is a terminal whose data importance does not exceed a preset importance. Access suspension notification information refers to information broadcast by a base station, used to notify non-important terminals to suspend access to the network, that is, to notify non-important terminals to remain silent.

[0051] In a specific implementation, after determining that the number of important terminals currently attempting access exceeds a preset number, access suspension notification information can be broadcast to notify non-important terminals to suspend access, thereby increasing the access probability of important terminals and avoiding affecting the normal operation of key services.

[0052] Step 150: Do not broadcast the access suspension notification information.

[0053] In a specific implementation, after determining that the number of important terminals currently attempting to access does not exceed a preset number, the access suspension notification information may not be broadcast, and each terminal within the coverage of the base station may attempt to access the network according to normal access procedures and rules.

[0054] The access control method for 5G lightweight terminals based on electric power services provided in an embodiment of the present invention first broadcasts access resource configuration information, so that each terminal sends an access request to the base station via the monitoring channel based on the access configuration information of the monitoring channel. Furthermore, each terminal selects the corresponding candidate data transmission channel based on the access configuration information of each candidate data transmission channel to send an access request to the base station, ensuring that each terminal can correctly and efficiently communicate with the base station. The number of important terminals currently attempting access is then determined based on the access request information received on the monitoring channel, providing a data basis for subsequently determining whether to broadcast a suspended access notification message. A determination is then made as to whether the number of important terminals currently attempting access exceeds a preset number. If not, the suspended access notification message is not broadcast. If so, the suspended access notification message is broadcast to notify non-important terminals to suspend access, thereby increasing the access probability of important terminals and avoiding impacting the normal operation of critical services. Therefore, the present invention can address the problem in the prior art of random access, where terminals carrying important service data and terminals carrying ordinary service data have the same access probability, resulting in high data transmission delays for important service data, which in turn impacts the normal operation of critical services.

[0055] Figure 2a Another flow chart of the access control method for 5G lightweight terminals based on power services provided in an embodiment of the present invention is a specific embodiment based on the above embodiment. In this embodiment, the method may also include:

[0056] Step 210: Broadcast access resource configuration information so that each terminal sends access request information to the base station through the monitoring channel according to the access configuration information of the monitoring channel, and enables each terminal to select the corresponding candidate data transmission channel according to the access configuration information of each candidate data transmission channel to send access request information to the base station.

[0057] Step 211: perform signal sampling on the access request information received on the monitoring channel within a preset time period to obtain a sampling result.

[0058] Specifically, the preset period is a time period set in advance based on actual conditions or needs to help determine the number of significant terminals currently attempting access. For example, the preset period could be two seconds after the access resource configuration information is broadcast. The sampling result refers to a series of discrete sample data points obtained by sampling the access request information signal.

[0059] In the specific implementation, the sampling frequency is first set according to the actual situation or needs. Then, during the entire preset period, the monitoring device will receive the access request information from the monitoring channel and store it as a digital signal. Then, the access request information received by the monitoring channel is continuously sampled according to the determined sampling frequency to obtain the sampling results.

[0060] In this embodiment, by sampling the access request information received on the monitoring channel within a preset period of time, a sampling result is obtained, which provides a data basis for subsequently determining the amplitude of each sampling point.

[0061] Step 212: Determine the amplitude of each sampling point in the sampling result.

[0062] Specifically, amplitude refers to the signal strength represented by the sampling point.

[0063] In a specific implementation, the value corresponding to each sampling point in the sampling result is determined as the amplitude of each sampling point.

[0064] In this embodiment, by determining the amplitude of each sampling point in the sampling result, a data basis is provided for subsequently determining the current energy of the monitoring channel.

[0065] Step 213: Determine the current energy of the monitoring channel according to the amplitude of each sampling point.

[0066] In specific implementation, the current energy of the monitoring channel can be determined based on the amplitude of each sampling point. The specific calculation formula is as follows:

[0067] E=|A i | 2

[0068] Among them, E represents the current energy of the monitoring channel, A i amplitude represents the amplitude of the i-th sampling point.

[0069] In this embodiment, by monitoring the current energy of the channel, a data basis is provided for subsequently determining the number of important terminals currently attempting to access.

[0070] Step 214: Determine the number of important terminals currently attempting to access based on the current energy of the monitoring channel and the preset terminal energy.

[0071] Specifically, the preset terminal energy refers to an energy value of a terminal set in advance according to actual conditions or needs.

[0072] In a specific implementation, in actual applications, it can be determined that the number of important terminals currently attempting to access = current energy of the monitoring channel / preset terminal energy.

[0073] In one embodiment, determining the number of important terminals currently attempting access based on access request information received by the monitoring channel includes: determining the number of access request information currently received by the monitoring channel within a preset time period as the number of important terminals currently attempting access.

[0074] In a specific implementation, a counter can be set to count the number of access requests received on the monitoring channel. Then, at the start of a preset period, the timer is immediately started and the counter value is initialized to 0. Whenever an access request is received on the monitoring channel, the counter value is incremented by 1. At the end of the preset period, the timer stops counting and the timer value is determined to be the number of important terminals currently attempting access.

[0075] In this embodiment, through the above steps, the speed of determining the number of important terminals currently attempting access is increased, thereby improving the overall efficiency.

[0076] Step 215: Determine whether the number of important terminals currently attempting to access exceeds a preset number.

[0077] If it exceeds, execute step 216; if it does not exceed, execute step 217.

[0078] Step 216: Do not broadcast the access suspension notification information.

[0079] Step 217: Broadcast access suspension notification information.

[0080] Step 218: Determine whether the target data transmission channel is available based on the access request information received by the target data transmission channel within a preset time period.

[0081] If available, execute step 220; if not available, execute step 219.

[0082] Specifically, each terminal includes a target terminal, and the candidate data transmission channel selected by the target terminal is the target data transmission channel.

[0083] In a specific implementation, the number of access request messages received by the target data transmission channel can be used to determine whether a terminal has attempted to access or has already accessed the target data transmission channel. If the number is zero, it means that no terminal has performed access-related operations with the target data transmission channel, and the target data transmission channel can be determined to be available. If the number is not zero, the database of authorized channel use records based on the target data transmission channel is checked to determine whether the target data transmission channel is occupied. If the authorized channel use record of the target data transmission channel shows that the target data transmission channel has been authorized and the authorization time has not yet expired, the target data transmission channel is determined to be unavailable; if the authorization time has expired or there is no relevant authorization record, the target data transmission channel is determined to be available.

[0084] After determining that the target data transmission channel is available, an access permission request can be sent to the target terminal via the target data transmission channel, so that the target terminal sends identity authentication information to the base station according to the access permission request. After determining that the target data transmission channel is unavailable, no access permission request is sent to the target terminal.

[0085] Furthermore, when the target data transmission channel is available, it also includes: determining the frequency of the target terminal based on the access request information received by the target data transmission channel within a preset time period; if the frequency of the target terminal is not within the preset frequency range, determining that the frequency of the target terminal is out of sync, and sending frequency out of sync information to the target terminal through the target data transmission channel, so that the target terminal adjusts its own frequency according to the frequency out of sync information.

[0086] Specifically, the frequency of a target terminal refers to the frequency used by the target terminal during signal transmission and reception. A preset frequency range refers to a frequency range pre-set based on actual conditions or needs. Frequency desynchronization information refers to an indication sent by a base station to a target terminal via a target data transmission channel, notifying the target terminal that its frequency needs to be adjusted.

[0087] In a specific implementation, the frequency of the target terminal is extracted from the access request information received by the target data transmission channel within a preset time period; if the frequency of the target terminal is not within the preset frequency range, it is determined that the frequency of the target terminal is out of synchronization, and frequency out of synchronization information is sent to the target terminal through the target data transmission channel, so that the target terminal adjusts its own frequency according to the frequency out of synchronization information.

[0088] In this embodiment, through the above steps, signal interference is reduced and communication quality is ensured.

[0089] Step 219: Do not send an access permission request to the target terminal.

[0090] Specifically, the access permission request refers to a notification message sent to the target terminal through the target data transmission channel, which is used to notify the target terminal that the base station allows it to attempt to access the network and requires the target terminal to provide identity authentication information to complete the subsequent access process.

[0091] In a specific implementation, after determining that the target data transmission channel is unavailable, no access permission request is sent to the target terminal to avoid invalid operations, and the target terminal reselects a channel and attempts to access again after not receiving the access permission request within the preset receiving time.

[0092] Step 220: Send an access permission request to the target terminal through the target data transmission channel, so that the target terminal sends identity authentication information to the base station according to the access permission request.

[0093] Specifically, identity authentication information refers to relevant data (such as a combination of a user name and password, and encrypted data corresponding to a digital certificate) sent by the target terminal to the base station in order to prove its legal identity.

[0094] In a specific implementation, after determining that the target data transmission channel is available, an access permission request is sent to the target terminal through the target data transmission channel, so that the target terminal sends identity authentication information to the base station according to the access permission request, helping to ensure network security.

[0095] Step 221: Receive identity authentication information sent by the target terminal.

[0096] In a specific implementation, the identity authentication information sent by the target terminal may be received through the target data transmission channel.

[0097] Step 222: Determine whether the target terminal is a legitimate terminal based on the identity authentication information sent by the target terminal.

[0098] If it is a legitimate terminal, execute step 224; if it is not a legitimate terminal, execute step 223.

[0099] Specifically, a legitimate terminal refers to a terminal in a communication network system that is identified by a base station as having the authority to access the network after verification by an authentication mechanism.

[0100] In a specific implementation, after receiving the identity authentication information sent by the target terminal, it can be determined whether the target terminal is a legitimate terminal based on the identity authentication information sent by the target terminal. If it is a legitimate terminal, transmission permission information is sent to the target terminal; if it is not a legitimate terminal, transmission permission information is not sent to the target terminal.

[0101] For example, if the authentication information is a username and password combination, the received username and password are extracted and then the corresponding username is searched in the authentication database. If a matching username is found, the received password is compared with the encrypted password stored in the database. If the password comparison is successful, the target terminal is determined to be legitimate.

[0102] In this embodiment, by determining whether the target terminal is a legitimate terminal, the intrusion of illegal terminals is prevented, and the security of network resources and data is guaranteed.

[0103] Step 223: Do not send transmission permission information to the target terminal.

[0104] Specifically, the transmission permission information refers to authorization information sent by the base station to the target terminal after confirming that the target terminal is a legitimate terminal.

[0105] In a specific implementation, after determining that the target terminal is not a legitimate terminal, no transmission permission information is sent to the target terminal to avoid invalid operations, so that the target terminal reselects a channel and tries to access again after failing to receive the transmission permission information within the preset receiving time.

[0106] Step 224: Send transmission permission information to the target terminal.

[0107] In a specific implementation, after determining that the target terminal is a legitimate terminal, transmission permission information can be sent to the target terminal through the target data transmission channel to complete the access process, and the target terminal can start a business connection after receiving the transmission permission information, for example: the business can be an electricity business.

[0108] Therefore, the technical solution of the present invention first broadcasts access resource configuration information, enabling each terminal to send access request information to the base station via the monitoring channel based on the access configuration information of the monitoring channel. Furthermore, each terminal selects the corresponding candidate data transmission channel based on the access configuration information of each candidate data transmission channel to send access request information to the base station, ensuring that each terminal can correctly and efficiently communicate with the base station. Then, signal sampling is performed on the access request information received on the monitoring channel within a preset time period to obtain a sampling result. The amplitude of each sampling point in the sampling result is then determined. The current energy of the monitoring channel is then determined based on the amplitude of each sampling point, providing a data basis for subsequently determining the number of important terminals currently attempting access. The number of important terminals currently attempting access is then determined based on the access request information received on the monitoring channel, providing a data basis for subsequently determining whether to broadcast a suspended access notification message. A determination is then made as to whether the number of important terminals currently attempting access exceeds a preset number. If not, the suspended access notification message is not broadcast. If so, the suspended access notification message is broadcast to notify non-important terminals to suspend access, thereby increasing the access probability of important terminals and avoiding impacting the normal operation of critical services. The availability of the target data transmission channel is then determined based on the access request information received on the target data transmission channel within a preset time period. If it is not available, no access permission request is sent to the target terminal. If it is available, an access permission request is sent to the target terminal via the target data transmission channel, so that the target terminal sends identity authentication information to the base station according to the access permission request. The identity authentication information sent by the target terminal is then received. Whether the target terminal is a legitimate terminal is determined based on the identity authentication information sent by the target terminal, thereby preventing the intrusion of illegal terminals and ensuring the security of network resources and data. If it is not a legitimate terminal, no transmission permission information is sent to the target terminal, so that the target terminal reselects a channel and attempts to access again after not receiving the transmission permission information within the preset receiving time. If it is a legitimate terminal, transmission permission information is sent to the target terminal to complete the access process, and the target terminal starts the service connection after receiving the transmission permission information. Therefore, the present invention can solve the problem that in the random access process of the prior art, terminals carrying important service data and terminals carrying ordinary service data have the same access probability, which may cause important service data to face higher data transmission delays, thereby affecting the normal operation of key services.

[0109] Figure 2b This is an example diagram of interaction between a terminal and a base station provided in an embodiment of the present invention. Figure 2bAs shown, the base station first broadcasts access resource configuration information (including access configuration information for the monitoring channel and access configuration information for each candidate data transmission channel). After receiving the access resource configuration information, the terminal determines whether its data importance exceeds a preset importance. If so, it sends an access request to the base station via the monitoring channel and selects a corresponding candidate data transmission channel based on the access configuration information for each candidate data transmission channel. If not, it selects a corresponding candidate data transmission channel based on the access configuration information for each candidate data transmission channel and sends an access request to the base station. The base station then determines the number of important terminals currently attempting access based on the access request information received on the monitoring channel. If the number of important terminals currently attempting access exceeds a preset number, it broadcasts an access suspension notification to notify non-important terminals to suspend access. The terminal then determines whether the transmission channel is available based on access request information received on the candidate data transmission channel selected by the terminal within a preset time period. If not, the terminal directly determines whether the transmission channel is available based on access request information received on the candidate data transmission channel selected by the terminal within the preset time period. If available, an access permission request is sent to the terminal via the data transmission channel. If not, no access permission request is sent to the terminal. After receiving the access permission request, the terminal first confirms whether it has received the access suspension notification information. If it receives the access suspension notification information, it determines whether the importance of its own data exceeds the preset importance. If it exceeds, it sends identity authentication information to the base station. If it does not exceed, it remains silent. If it does not receive the access suspension notification information, it sends identity authentication information to the base station. After receiving the identity authentication information, the base station determines whether the terminal is a legitimate terminal based on the identity authentication information; if it is a legitimate terminal, it sends transmission permission information to it, otherwise it does not send it. After receiving the transmission permission information, the terminal completes the receiving process and establishes a service connection with the base station. In addition, after determining that the aforementioned data transmission channel is available, the base station can also determine the frequency of the aforementioned terminal based on the access request information received on the data transmission channel within a preset time period; if the frequency of the terminal is not within the preset frequency range, it determines that the frequency of the terminal is asynchronous, and sends frequency asynchronous information to the terminal through the data transmission channel. After receiving the frequency asynchronous information, the terminal can adjust its own frequency according to the frequency asynchronous information.
