[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0047] In the embodiments of the present application, the terminal can refer to a RedCap terminal, and the embodiments of the present application are applied to an electronic device, which can be a base station or the like.

[0048] Referring to Figure 1 , Figure 1 is one of the flowcharts of the terminal access control method provided by the embodiments of the present application, as shown in Figure 1 , the method comprises the following steps:

[0049] Step 101: based on the service corresponding to the terminal, at least two terminals are divided into at least two terminal categories.

[0050] The electronic device can divide the terminals based on the service corresponding to the terminal. The electronic device can also divide the terminals based on the device type of the terminal, the data transmitted by the terminal, and other dimensions. In embodiments of the present application, the manner of dividing the terminals is not limited.

[0051] Step 102: in the case where the network load parameter of the first cell matches the first preset network load parameter, and / or the network load parameter of all categories of terminals matches the second preset network load parameter, the behavior of the terminals of the target category accessing the first cell is controlled, and the at least two terminal categories include the target category.

[0052] In embodiments of the present application, the electronic device divides at least two terminals into at least two terminal categories. In the case where the network load parameter of the first cell matches the first preset network load parameter, and / or the network load parameter of all categories of terminals matches the second preset network load parameter, the behavior of the terminals of the target category accessing the first cell is controlled. In this process, the control of the terminals accessing the first cell is realized, the terminal equipment resources of the user are prevented from being occupied by the terminals, network congestion is avoided, and the experience of the user accessing the Internet through the user terminal equipment is improved.

[0053] In some embodiments, the terminal categories include a first terminal category, a second terminal category, and a third terminal category, the service priority of the first terminal category is greater than the service priority of the second terminal category, the service priority of the second terminal category is greater than the service priority of the third terminal category, the terminals of the target category include terminals in the second terminal category and / or terminals in the third terminal category, and the method further includes:

[0054] The network is sliced based on the network resource type and the network usage scenario to obtain at least one network slice, the at least one network slice includes a first network slice, a second network slice, and a third network slice; the terminals in the first terminal category access the network through the first network slice, the terminals in the second terminal category access the network through the second network slice, and the terminals in the third terminal category access the network through the third network slice;

[0055] The control of the behavior of the terminals of the target category accessing the first cell includes:

[0056] According to the service priority, the terminals in the second terminal category are controlled to access the second network slice, and / or the terminals in the third terminal category are controlled to access the third network slice.

[0057] In this embodiment, the electronic device can divide the terminals into three terminal categories according to the services corresponding to the terminals. For example, the electronic device takes the terminals responsible for critical services as the first terminal category, the electronic device takes the terminals responsible for regular services as the second terminal category, and the electronic device takes the terminals responsible for low-time-sensitive services as the third terminal category. Among them, the critical services can be industrial control services, emergency alarm services, etc., the regular services can be environmental monitoring services, smart meter services, etc., and the low-time-sensitive services can be batch data transmission services, etc.

[0058] The priority of the terminal category is related to the priority of the service to which the terminal belongs. The higher the priority of the terminal category, the more the electronic device will guarantee the terminal access. For example, the first terminal category has the highest service priority, and the electronic device will unconditionally guarantee the access of the first terminal category. The service priority of the second terminal category is lower than that of the first terminal category, and when the network resource is tight, the electronic device will limit the access of the second terminal category. The service priority of the third terminal category is lower than that of the second terminal category, and the electronic device only allows the terminal to access when the network resource is not tight, such as during off-peak hours. Among them, when the terminal is registered, the service priority label can be carried through non-access layer signaling or pre-configuration. The service priority label can be represented by an extension field of the quality of service level identifier. In some embodiments, the electronic device can also divide the terminals into two terminal categories or four or more terminal categories based on the services, which is not limited here.

[0059] In addition to dividing the terminal category, the electronic device can also slice the network based on the network resource type and the network usage scenario. For example, the electronic device can slice the network through logical isolation, network resource customization, and actual network usage scenario, etc. to obtain three network slices. Optionally, the first network slice can be a critical Internet of Things slice, the second network slice can be a large connection slice, and the third network slice can be an elastic slice. The critical Internet of Things slice is used for a network responsible for high-reliability services such as industrial control and vehicle networking, and exclusively occupies high-frequency resources. The large connection slice is used for a network responsible for a large number of low-power terminals such as smart meters, and narrowband configuration and low-power strategies are adopted during network connection. The elastic slice is used for a network responsible for burst data backhaul services, and supports dynamic resource expansion and contraction. Different network resource types and network usage scenarios correspond to different priorities of the network slice, for example, the priority of the first network slice is greater than that of the second network slice, and the priority of the second network slice is greater than that of the third network slice. In some embodiments, the electronic device can also divide the network into two network slices or four or more network slices, which is not limited here.

[0060] When the terminal device is connected to the network through the network slice, the electronic device can select a suitable slice according to the service type or identifier of the terminal device based on the comprehensive data management strategy. For example, the terminals in the first terminal category are connected to the network through the first network slice, the terminals in the second terminal category are connected to the network through the second network slice, and the terminals in the third terminal category are connected to the network through the third network slice.

[0061] Optionally, the electronic device can coordinate the state of each network slice through the core network (such as the 5G network data analysis function) to ensure that the high-priority network slice (such as the key Internet of Things slice) is not interfered with by the low-priority network slice (such as the large connection slice or the elastic slice). In the case that the network slice where the terminal is located is overloaded and the terminal supports multi-slice access, the electronic device can guide the terminal to switch to a low-load slice in the same scenario. The electronic device can monitor indicators such as the occupancy rate of the physical resource block of each network slice, the number of users using the network, and the network traffic load value, and independently set the access control threshold of each slice network to enable the terminal to temporarily borrow resources of other idle network slices when a certain network slice is overloaded. The terminal cannot borrow a higher-priority network slice, and the resources of the key network slice must be protected.

[0062] When controlling the access behavior of the terminal, the electronic device can control the access behavior of the terminal of at least part of the terminal categories according to the service priority. For example, at least part of the terminal categories can be the second terminal category and the third terminal category. In an example, the electronic device can determine the access probability of each terminal category based on the service priority, and then realize the access of the terminal according to the service priority. For example, the electronic device ensures that the access rate of the first terminal category is 100%, the access rate of the second terminal category is 50%, and the access rate of the third terminal category is 20%, that is, all terminals of the first terminal category can access the first network slice, only 50% of the terminals of the second terminal category can access the second network slice, and only 20% of the terminals of the third terminal category can access the third network slice. The electronic device can select the terminals of the second terminal category and the first terminal category that can access the network slice through a random algorithm. For example, in the case that the network load parameter of the first cell matches the first preset network load parameter, and / or the network load parameter of all categories of terminals matches the second preset network load parameter, the electronic device ensures that all terminals of the first terminal category access the first cell, and first limits the terminals of the third terminal category to access the first cell, and then limits the terminals of the second terminal category to access the first cell.

[0063] It can be understood that in this embodiment, the electronic device sets different network slices and divides the terminals into different terminal categories to better control the access behavior of the terminals.

[0064] The conditions of triggering the access behavior control of the terminal are described in detail as follows.

[0065] In some embodiments, the access behavior of the terminal of the target category to the first cell is controlled under the condition that the network load parameter of the first cell matches the first preset network load parameter and / or the network load parameter of the terminal of all categories matches the second preset network load parameter, including:

[0066] The access behavior of the terminal of the target category to the first cell is controlled under the condition that the network load parameter of the first cell matches the first preset network load parameter and / or the network load parameter of the terminal of all categories matches the second preset network load parameter within a preset time period.

[0067] In this embodiment, the electronic device can set a preset time period and monitor and count the network load parameter of the first cell and the network load parameter of the terminal of all categories within the preset time period. When the network load parameter of the first cell matches the first preset network load parameter and / or the network load parameter of the terminal of all categories matches the second preset network load parameter within the preset time period, the electronic device can control the access behavior of the terminal, prevent the terminal from occupying the resources of the user terminal device, avoid network congestion, and improve the user experience of the user accessing the network through the user terminal device.

[0068] In some embodiments, the preset time period includes at least one target preset time period, and different target preset time periods correspond to different first preset network load parameters and / or second preset network load parameters.

[0069] It can be understood that in this embodiment, the electronic device can set multiple target preset time periods. For different target preset time periods, the electronic device can set different first preset network load parameters and / or second preset network load parameters to more accurately control the access behavior of the terminal. In some embodiments, the first preset network load parameters and / or the second preset network load parameters corresponding to different target preset time periods can also be the same, which is not limited herein.

[0070] In some embodiments, the network load parameter includes at least one of the following: physical resource block occupation rate, number of users using the network, network traffic load value; and the access behavior of the terminal of the target category to the first cell is controlled under the condition that the network load parameter of the first cell matches the first preset network load parameter, including at least one of the following:

[0071] the physical resource block occupation rate of the first cell is greater than a first preset physical resource block occupation rate;

[0072] the number of network users of the first cell is greater than a first preset number of network users, the behavior of the terminal of the target category accessing the first cell is controlled;

[0073] the network traffic load value of the first cell is greater than a first preset network traffic load value, the behavior of the terminal of the target category accessing the first cell is controlled;

[0074] the network load parameter of all categories of terminals matches a second preset network load parameter, the behavior of the terminal of the target category accessing the first cell is controlled, including at least one of the following:

[0075] the physical resource block occupation rate of all categories of terminals is greater than a second preset physical resource block occupation rate, the behavior of the terminal of the target category accessing the first cell is controlled;

[0076] the number of network users of all categories of terminals is greater than a second preset number of network users, the behavior of the terminal of the target category accessing the first cell is controlled;

[0077] the network traffic load value of all categories of terminals is greater than a second preset network traffic load value, the behavior of the terminal of the target category accessing the first cell is controlled.

[0078] It can be understood that in this embodiment, the electronic device can control the access behavior of the terminal when detecting any of the following conditions. For example, the electronic device can control the access behavior of the terminal when the physical resource block occupation rate of the first cell is greater than a first preset physical resource block occupation rate, or the number of network users of the first cell is greater than a first preset number of network users, or the network traffic load value of the first cell is greater than a first preset network traffic load value, or the physical resource block occupation rate of all categories of terminals is greater than a second preset physical resource block occupation rate, or the number of network users of all categories of terminals is greater than a second preset number of network users, or the network traffic load value of all categories of terminals is greater than a second preset network traffic load value. This process can achieve precise control of the access behavior of the terminal by the electronic device.

[0079] The process of triggering the access behavior of the terminal is specifically described below through an example.

[0080] In an example, the electronic device can divide the preset time period of the first cell into peak time periods and non-peak time periods according to historical data of the first cell and other cells, wherein there are multiple peak time periods and non-peak time periods per day.

[0081] For convenience of description, the example assumes that there is only one peak per day and only one non-peak. The electronic device can further determine, according to the historical data, the physical resource block occupation rate of the first cell in the peak time period , the number of users using the network , and the network traffic load value , each corresponding to a first preset physical resource block occupation rate , a first preset number of users using the network , and a first preset network traffic load value . Similarly, the electronic device can further determine, based on the historical data, the physical resource block occupation rate of the first cell in the non-peak time period , the number of users using the network , and the network traffic load value , each corresponding to a third preset physical resource block occupation rate , a third preset number of users using the network , and a third preset network traffic load value . Similarly, the electronic device can also set the physical resource block occupation rate of all categories of terminals in the peak time period , the number of users using the network , and the network traffic load value , each corresponding to a second preset physical resource block occupation rate , a second preset number of users using the network , and a second preset network traffic load value . Similarly, the electronic device can also set the physical resource block occupation rate of all categories of terminals in the non-peak time period , the number of users using the network , and the network traffic load value , each corresponding to a fourth preset physical resource block occupation rate , a fourth preset number of users using the network , and a fourth preset network traffic load value . The second preset physical resource block occupation rate and the fourth preset physical resource block occupation rate are determined based on the physical resource block occupation rate corresponding to the first cell, the second preset number of users using the network and the fourth preset number of users using the network are determined based on the number of users using the network corresponding to the first cell, and the second preset network traffic load value and the fourth preset network traffic load value are determined based on the network traffic load value corresponding to the first cell.

[0082] For example, in the peak period, the control of the terminal access behavior is triggered when any of the following conditions is met. Condition 1: in the case where the number of network users in the first cell is greater than the first preset number of network users, it is determined whether the physical resource block occupation rate of all categories of terminals is greater than the second preset physical resource block occupation rate. In the case where the physical resource block occupation rate of all categories of terminals is greater than the second preset physical resource block occupation rate, the electronic device controls the terminal access behavior. Condition 2: in the case where the number of network users in the first cell is greater than the first preset number of network users, it is determined whether the number of network users of all categories of terminals is greater than the second preset number of network users. In the case where the number of network users of all categories of terminals is greater than the second preset number of network users, the electronic device controls the terminal access behavior. Condition 3: in the case where the network traffic load value of the first cell is greater than the first preset network traffic load value, it is determined whether the network traffic load value of all categories of terminals is greater than the second preset network traffic load value. In the case where the network traffic load value of all categories of terminals is greater than the second preset network traffic load value, the electronic device controls the terminal access behavior.

[0083] The following will be a specific description of how the electronic device controls the terminal access behavior.

[0084] In some embodiments, the control of the behavior of the target category of terminals accessing the first cell includes:

[0085] modifying the information corresponding to the target category of terminals in the system information block to control the behavior of the target category of terminals accessing the first cell;

[0086] or, in the case where the access request message sent by the target category of terminals is received, the access of the target category of terminals is rejected.

[0087] In this embodiment, the electronic device can select a suitable method to control the terminal access based on the base station capability and the terminal capability. For example, the electronic device can control the terminal access by modifying the information corresponding to the terminal in the system information block, or the electronic device can reject the terminal access after receiving the access request message sent by the terminal. In this process, the electronic device can better control the terminal access behavior.

[0088] In some embodiments, the modification of the information corresponding to the target category of terminals in the system information block to control the behavior of the target category of terminals accessing the first cell includes:

[0089] modifying the protocol field value corresponding to the target category of terminals in the system information block;

[0090] Or, a first information element corresponding to the terminal of the target category in the system information block is configured as a preset field; the first information element is used to reject access of the terminal of the target category.

[0091] Or, a second information element corresponding to the terminal of the target category in the system information block is deleted; the second information element is used to make the terminal of the target category select a cell other than the first cell.

[0092] In this embodiment, the way in which the electronic device modifies the information corresponding to the terminal in the system information block can be: modifying a protocol field (such as an intraFreqReselectionRedCap field) to notAllowed; or configuring a first information element (such as a cellBarredRedCap1Rx-r17 information element) as a barred field, and not carrying a halfDuplexRedCapAllowed-r17 information element; or deleting a second information element (such as an intraFreqReselectionRedCap information element), so that the second information element is missing.

[0093] It can be understood that, in this embodiment, the electronic device can better control the access behavior of the terminal by modifying the information corresponding to the terminal in the system information block.

[0094] In some embodiments, the rejecting, in a case where the access request message sent by the terminal of the target category is received, the access of the terminal of the target category comprises:

[0095] ignoring the access request message in a case where the access request message sent by the terminal of the target category is received;

[0096] Or, replying, in a case where the access request message sent by the terminal of the target category is received, a rejection access message to the terminal of the target category;

[0097] Or, adding, in a case where the access request message sent by the terminal of the target category is received, the terminal of the target category to a blacklist.

[0098] In this embodiment, there is message interaction between the electronic device and the terminal, and the electronic device can control the access behavior of the terminal in the process of message interaction.

[0099] For example, when the terminal sends an access request message (such as Message1) to the electronic device for the first time, the electronic device ignores the access request message to achieve control of the access behavior of the terminal.

[0100] Alternatively, when the terminal sends an access request message to the electronic device for the second time (such as Message 3), the electronic device identifies that it is an access request message of the terminal, and then ignores the access request message or replies with an RRCReject message. When the electronic device replies with an RRCReject message, the content of the RRCReject message needs to be configured to reply to an RRCSetUpRequest. If an RRCResumeRequest is replied to, the terminal will send an access request message again, causing signaling congestion.

[0101] Alternatively, if the electronic device ignores the access request message, the terminal will consider that the terminal itself does not receive the access message issued by the electronic device after observing that the electronic device ignores the access request message, which will cause the terminal to re-initiate the access process. Therefore, the electronic device can introduce a dynamic blacklist mechanism to temporarily mark the terminal that frequently attempts to access but is rejected and add it to the blacklist to reduce invalid signaling interaction.

[0102] It can be understood that in this embodiment, the electronic device can reject the access of the terminal after receiving the access request message sent by the terminal, so as to better control the access behavior of the terminal.

[0103] In some embodiments, when there are too many users in the cell, the electronic device can control the access of the terminal by modifying the information corresponding to the terminal in the system information block, which can increase the parsing overhead of the terminal, cause the power consumption of the terminal to rise, and the access process needs to process additional signaling. Therefore, when the electronic device triggers the access control of the terminal, the electronic device can process the access requests of the terminals in a period in batches instead of processing and intercepting one by one, so as to reduce the risk of signaling storm.

[0104] In some embodiments, when the electronic device does not trigger the access control of the terminal, the electronic device can restore the normal access of the terminal, that is, cancel the access control of the terminal.

[0105] For example, when the physical resource block occupation rate of the first cell is less than or equal to a first preset physical resource block occupation rate, or the number of users using the network of the first cell is less than or equal to a first preset number of users using the network, or the network traffic load value of the first cell is less than or equal to a first preset network traffic load value, or the physical resource block occupation rate of all categories of terminals is less than or equal to a second preset physical resource block occupation rate, or the number of users using the network of all categories of terminals is less than or equal to a second preset number of users using the network, or the network traffic load value of all categories of terminals is less than or equal to a second preset network traffic load value, the electronic device can control the access behavior of the terminal.

[0106] The scheme for the electronic device to recover the normal access of the terminal can be: modifying the intraFreqReselectionRedCap field to allowed; or configuring the cellBarredRedCap1Rx-r17 information element to notBarred; or configuring the cellBarredRedCap2Rx-r17 information element to notBarred; or carrying the halfDuplexRedCapAllowed-r17 information element. In addition, the electronic device responds to the access request message when the terminal sends the access request message to the electronic device for the first time (such as Message1), or the electronic device responds to the access request message when the terminal sends the access request message to the electronic device for the second time (such as Message3). In the embodiments of the present application, the scheme for the electronic device to recover the normal access of the terminal is not limited.

[0107] The terminal access control method of the present application will be further described below. Figure 2 The terminal access control method of the present application will be further described below.

[0108] Step 201: slicing the network based on the network resource type and the network usage scenario to obtain at least one network slice; and dividing at least two terminals into at least two terminal categories based on the services corresponding to the terminals.

[0109] Step 202: determining a first preset network load parameter corresponding to the network load parameter of the first cell, and determining a second preset network load parameter corresponding to the network load parameter of all categories of terminals.

[0110] Step 203: determining whether the network load parameter of the first cell matches the first preset network load parameter, and / or whether the network load parameter of all categories of terminals matches the second preset network load parameter.

[0111] In the case where the network load parameter of the first cell matches the first preset network load parameter, and / or the network load parameter of all categories of terminals matches the second preset network load parameter, step 204 is performed, otherwise step 207 is performed.

[0112] Step 204: allocating the terminals of different terminal categories to the corresponding network slices.

[0113] Step 205: the electronic device starts to control the access behavior of the terminal. For example, the electronic device controls the access of the terminal by modifying the information corresponding to the terminal in the system information block, or the electronic device can refuse the access of the terminal after receiving the access request message sent by the terminal.

[0114] Step 206: the electronic device performs batch processing on the terminal access requests in a period.

[0115] Step 207: The electronic device does not control the access behavior of the terminal.

[0116] Through the above steps 201-207, the control of the terminal accessing the first cell can be realized, the terminal from occupying the user terminal device resources can be prevented, the network congestion can be avoided, and the experience of the user using the user terminal device to surf the Internet can be improved.
