[0019] FIG. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application can be applied.

[0020] The following describes in detail the access control method according to the embodiment of the present application through specific embodiments and application scenarios in conjunction with the drawings.

[0021] An embodiment of the present application provides an access control method. FIG. 2 is a flowchart of the access control method of the embodiment of the present application. As shown in FIG. 2, the steps of the method include: A step S202 in which a first type of terminal obtains a first access control parameter different from a second access control parameter corresponding to a second type of terminal; The first type of terminal performs access control based on the first access control parameter in a step S204.

[0022] Through the above steps S202 and S204, a first type of terminal can obtain a corresponding first access control parameter to perform access control, which is different from the second access control parameter corresponding to a second type of terminal, i.e., different types of terminals can obtain corresponding access control parameters, thereby solving the problem in the prior art that one type of terminal affects the access control of another type of terminal after a large number of accesses by all different types of terminals sharing one set of the same access control parameters.

[0023] It should be noted that the first type of terminal in the embodiment of the present application is a lightweight terminal, and the second type of terminal is a general terminal. Furthermore, a general terminal may be understood as a non-lightweight terminal, or a general type of terminal defined in Rel15 or Rel16. A lightweight terminal (abbreviated as light / lite UE, reduced capability UE, NR-light / Lite or RedCap UE) is mainly applied to wearable devices, industrial sensor terminals in factory environments, or video monitoring equipment. This type of terminal refers to equipment with limited capabilities, such as lower device complexity, smaller device size, weaker processing power, smaller or fewer supportable characteristics, etc.

[0024] It should be noted that the first access control parameter and / or the second access control parameter in the embodiment of the present application may be configured by the network side or negotiated by a protocol. In addition, the first access control parameter or the second access control parameter in the embodiment of the present application may be: 1) Access control type, such as Unified Access Control (UAC), Access Class Barring (ACB), Access Barring (AB), Application Specific Congestion Control for Data Communication (ACDC), and 2) access controlled public land mobile network information; and 3) A probability parameter for access control; and 4) Access control access barring factor (e.g., AC_BarringFactor); 5) Information related to the time length of access control (e.g., barTimer); 6) Access identifier information (e.g., access ID) corresponding to access control; 7) Access type information (e.g., access category) corresponding to the access control; 8) Access control level information (e.g., AC_Barring forSpecialAC), 9) Radio Resource Control (RRC) connection establishment cause; 10) type of access attempt; 11) Event information corresponding to access control.

[0025] It should be noted that the above only describes that the first access control parameter and the second access control parameter have the above-mentioned multiple situations, and in a specific use case, the first access control parameter corresponds to a first type of terminal, and the second access control parameter corresponds to a second type of terminal, so the first access control parameter and the second access control parameter are different.

[0026] In an optional embodiment of the present application, the manner in which the first type terminal performs access control based on the first access control parameter in the above step S204 includes:

[0027] Method 1) performing a first target operation when it is determined that the cell in which the terminal is located prohibits access, does not allow access, or does not support a first type of terminal based on a first access control parameter; Here, the first target operation includes at least one of not allowing presence in the cell, prohibiting access to the cell or prohibiting access to the cell for a pre-set time, not accessing the cell, not allowing access attempts to the cell, and performing cell selection or reselection.

[0028] According to method 1), when a first type of terminal is currently connected and a large number of first type of terminals access the network, the network load distribution can be controlled by the first access control parameters.

[0029] Method 2) If it is determined that the cell in which the mobile station is located allows access, is not forbidden access, or supports a first type of terminal based on the access control parameters, then perform a second target operation; Here, the second target operation includes at least one of allowing presence in the cell, not prohibiting access to the cell, allowing access to the cell, allowing access attempts to the cell, and not performing cell selection or reselection.

[0030] According to method 2), if a first type terminal is currently in an idle state, the first access control parameter can be used to control a Random Access Channel (RACH) access initiated by the first type terminal without colliding with a second type terminal, thereby reducing the probability of RACH collision.

[0031] In an optional embodiment of the embodiment of the present application, the manner in which the first type terminal obtains the first access control parameter in step S202 of the embodiment of the present application may include at least one of the following:

[0032] 1) the first type of terminal obtains a first access control parameter corresponding to an attribute of the first type of terminal, where the attribute of the first type of terminal includes at least one of a capability of the first type of terminal, a capability set of the first type of terminal, a feature / functionality of the first type of terminal, a feature / functionality set of the first type of terminal, a category of the first type of terminal, a type of the first type of terminal, a use case of the first type of terminal, and subscription information of the first type of terminal; It should be noted that the above terminal types generally correspond to categories defined in a protocol, which may be defined based on feature sets or capability sets or different data rates, such as cat.1, cat.2, .... Different types may be defined based on feature sets or capability sets or different data rates, or for different types, the same category may correspond to different types, such as high end UE and low end UE. For different use cases, different categories or different types may correspond to different use cases, or the same type or type of terminal may be in different use cases, such as wearable devices applied to personal business and industry sensors in the industrial field. In either case, in the case of low end UE, a distinction can be made between low end wearable and low end industry sensor. The above subscription information generally refers to the subscription information of the UE, such as the corresponding subscription information of an operator in a SIM card, and includes at least one of SIM card type, SIM card service type, SIM card fee information, SIM card priority, or operator customer level, etc., and different initial access resources can be configured to correspond to different subscription information.

[0033] In a specific use case, the first type of terminal may be a terminal whose bandwidth capability is less than 700MHz, or whose number of antennas capability is less than 4 and equal to / 2 and equal to / 1, or whose peak rate capability is less than 700Mbps, or whose processing delay capability is less than a preset time, or whose number of supported carriers capability is less than a preset value, or whose transmission power capability is less than a preset value. Of course, the attributes of the first type of terminal are merely illustrative, and the attribute values ​​of the above first type of terminal may be correspondingly set or adjusted as necessary. That is, the corresponding initial access resources may be selected for the same type of terminal according to its attribute values.

[0034] 2) A first type of terminal obtains a first access control parameter corresponding to a slice supported by the first type of terminal or a corresponding slice.

[0035] 3) The first type of terminal obtains a first access control parameter corresponding to identifier information of the first type of terminal, where the identifier information includes at least one of an identifier of the first type of terminal, an identifier group of the first type of terminal, a number segment of the first type of terminal, a core network identifier corresponding to the first type of terminal, and an identifier group of the core network corresponding to the first type of terminal.

[0036] 4) The first type of terminal obtains a first access control parameter corresponding to the type of the first type of terminal.

[0037] 5) The first type of terminal obtains a first access control parameter corresponding to the type of the first type of terminal.

[0038] 6) The first type of terminal obtains first access control parameters corresponding to a use case of the first type of terminal.

[0039] It should be noted that the attributes of a first type of terminal, the slices supported by the first type of terminal or the corresponding slices, and the identifier information of the first type of terminal may be configured by the network side or agreed upon by a protocol.

[0040] In an alternative embodiment of the present application, the first type of terminal comprises: 1) Physical Broadcast Channel (PBCH) messages; and 2) Master Information Block (MIB) messages; and 3) System Information (SI) of a first System Information Block (SIB); 4) Dedicated Radio Resource Control (RRC) messages; and 5) acquiring the first access control parameter by at least one configuration message including the extended system information; Here, the first SIB is a system information block SIB corresponding to a second type of terminal.

[0041] Optionally, the extended system information in the embodiment of the present application may further include at least one of the following:

[0042] 1) System information corresponding to a first type of terminal in a first SIB1, where the first SIB1 is a SIB in a first SIB, and the first SIB is a SIB corresponding to a second type of terminal, i.e., this extended system information may be extended based on SIB1 to an additional SIB1 system message to allow support for the first type of terminal or to indicate allowing access for the first type of terminal.

[0043] 2) System information corresponding to a first type of terminal in SIBy, where y is an integer greater than 1, SIBy is a SIB in a first SIB, and the first SIB is a SIB corresponding to a second type of terminal. In this example, SIBy is an extension information element (IE) newly added to a certain existing SIB, and the extension information element includes system information of the first type of terminal.

[0044] 3) System information corresponding to a first type of terminal in SIBx, where x is an integer greater than 1, and SIBx is a SIB in a second SIB, and the second SIB is a SIB corresponding to the first type of terminal. In this example, SIBx is a newly added SIB in addition to the conventional SIB.

[0045] Optionally, in the embodiment of the present application, the first SIB1 may be referred to as SIB1-extend, which refers to an extension based on the conventional SIB1 and adding an additional SIB1 system message for allowing support of a second type of terminal or for indicating that the second type of terminal is allowed to access. In other words, the system information corresponding to the first type of terminal in the first SIB1 is used to indicate one of system information supporting the first type of terminal and system information allowing the first type of terminal to access or be present.

[0046] Furthermore, the SIBx may be understood as another SIB other than the second SIB1 in the newly added second SIB, and may be used to carry system information corresponding to the first type of terminal. The system information may indicate, explicitly or implicitly, at least one of whether the first cell supports the first type of terminal and whether the first cell allows the first type of terminal to access or be located. Here, the first cell is the terminal in which the first type of terminal is currently located.

[0047] The above SIBy may be understood as an SIB obtained by extending based on a conventional SIB after the first SIB1, for example, an SIB obtained by extending based on a certain SIB among conventional SIB2, SIB3, SIB4, SIBn, and this SIBy may be called SIB2-light, SIB3-light, SIB4-light, SIBn-light. SIBy includes system information required for a cell in which a first type of terminal is located, and this system information may indicate implicitly or explicitly at least one of whether the first cell supports the first type of terminal and whether the first cell allows the first type of terminal to access or reside.

[0048] Optionally, the system information corresponding to the first type of terminal in SIBx and SIBy is used to indicate system information required for accessing or camping on the cell in which the first type of terminal is located.

[0049] In a specific use case, if SIBx or SIBy indicates system information required for accessing or staying in the cell where the first type of terminal is located, the terminal may understand that the first cell supports the first type of terminal and allows the first type of terminal to access or stay, and can then perform the access or stay process. Of course, in another alternative implementation case, SIBx or SIBy may further include another indication identifier for indicating at least one of whether the first cell supports the first type of terminal and whether the first cell allows the first type of terminal to access or stay.

[0050] It should be noted that the values ​​of x and y may be indicated by some information elements (IEs) of a conventional SIB1 message.

[0051] While FIG. 2 above describes the access control method of the present application from the terminal side, the following describes the access control method of the present application from the network side.

[0052] FIG. 3 is a second flowchart of an access control method according to an embodiment of the present application. The method is used in a network side device. As shown in FIG. 3, the steps of the method include:

[0054] In an embodiment of the present application, the method of configuring corresponding access control parameters for different types of terminals in the above step S302 may further include configuring a first access control parameter for a first type of terminal, and configuring a second access control parameter for a second type of terminal, where the first type of terminal and the second type of terminal are different types of terminals, and the first access control parameter is different from the second access control parameter.

[0055] It should be noted that the first type of terminal in the embodiment of the present application is a lightweight terminal, and the second type of terminal is a general terminal. Furthermore, a general terminal may be understood as a non-lightweight terminal, or a general type of terminal defined in Rel15 or Rel16. A lightweight terminal (abbreviated as light / lite UE, reduced capability UE, NR-light / Lite or RedCap UE) is mainly applied to wearable devices, industrial sensor terminals in factory environments, or video monitoring equipment. This type of terminal refers to equipment with limited capabilities, such as lower device complexity, smaller device size, weaker processing power, smaller or fewer supportable characteristics, etc.

Different types may be defined based on feature sets or capability sets or different data rates, or for different types, the same category may correspond to different types, such as high end UE and low end UE. For different use cases, different categories or different types may correspond to different use cases, or the same type or type of terminal may be in different use cases, such as wearable devices applied to personal business and industry sensors in the industrial field. In either case, in the case of low end UE, a distinction can be made between low end wearable and low end industry sensor. The above subscription information generally refers to the subscription information of the UE, such as the corresponding subscription information of an operator in a SIM card, and includes at least one of SIM card type, SIM card service type, SIM card fee information, SIM card priority, or operator customer level, etc., and different initial access resources can be configured to correspond to different subscription information.

[0058] In a specific use case, the first type of terminal may be a terminal whose bandwidth capability is less than 700MHz, or whose number of antennas capability is less than 4 and equal to / 2 and equal to / 1, or whose peak rate capability is less than 700Mbps, or whose processing delay capability is less than a preset time, or whose number of supported carriers capability is less than a preset value, or whose transmission power capability is less than a preset value. Of course, the attributes of the first type of terminal are merely illustrative, and the attribute values ​​of the above first type of terminal may be correspondingly set or adjusted as necessary. That is, the corresponding initial access resources may be selected for the same type of terminal according to its attribute values.

[0059] 2) Configuring corresponding first access control parameters for the first type of terminal based on a slice supported by the first type of terminal or a corresponding slice.

[0060] 3) Arranging corresponding first access control information for the first type of terminal based on identifier information of the first type of terminal, where the identifier information includes at least one of an identifier of the first type of terminal, an identifier group of the first type of terminal, a number segment of the first type of terminal, a core network identifier corresponding to the first type of terminal, and an identifier group of the core network corresponding to the first type of terminal.

[0062] 5) configuring corresponding first access control information for the first type of terminal based on the type of the first type of terminal;

[0063] 6) configuring corresponding first access control information for the first type of terminal based on a use case of the first type of terminal;

[0064] Optionally, the access control parameters in the embodiment of the present application are: 1) Access control type, such as Unified Access Control (UAC), Access Class Barring (ACB), Access Barring (AB), Application Specific Congestion Control for Data Communication (ACDC), and 2) access controlled public land mobile network information; and 3) A probability parameter for access control; and 4) Access control access barring factor (e.g., AC_BarringFactor); 5) Information related to the time length of access control (e.g., barTimer); 6) Access identifier information (e.g., access ID) corresponding to access control; 7) Access type information (e.g., access category) corresponding to the access control; 8) Access control level information (e.g., AC_Barring forSpecialAC), 9) Radio Resource Control (RRC) connection establishment reason; 10) type of access attempt; 11) Event information corresponding to access control.

[0065] Optionally, in the embodiments of the present application, 1) Physical Broadcast Channel (PBCH) messages; and 2) Master Information Block (MIB) messages; and 3) System Information (SI) of a first System Information Block (SIB); 4) Dedicated Radio Resource Control (RRC) messages; and 5) Corresponding access control parameters may be configured for different types of terminals by a configuration message among the extended system information.

[0066] Here, the first SIB is a SIB corresponding to a second type of terminal.

[0067] Optionally, the extended system information in the embodiment of the present application may further include at least one of the following:

[0068] 1) System information corresponding to a first type of terminal in a first SIB1, where the first SIB1 is a SIB in a first SIB, and the first SIB is a SIB corresponding to a second type of terminal, i.e., this extended system information may be extended based on SIB1 to an additional SIB1 system message to allow support for the first type of terminal or to indicate allowing access for the first type of terminal.

[0069] 2) System information corresponding to a first type of terminal in SIBy, where y is an integer greater than 1, SIBy is a SIB in a first SIB, and the first SIB is a SIB corresponding to a second type of terminal. In this example, SIBy is an extension information element (IE) newly added to a certain existing SIB, and the extension information element includes system information of the first type of terminal.

[0070] 3) System information corresponding to a first type of terminal in SIBx, where x is an integer greater than 1, and SIBx is a SIB in a second SIB, and the second SIB is a SIB corresponding to the first type of terminal. In this example, SIBx is a newly added SIB in addition to the conventional SIB.

[0071] Optionally, in the embodiment of the present application, the first SIB1 may be referred to as SIB1-extend, which refers to an extension based on the conventional SIB1 and adding an additional SIB1 system message for allowing support of a second type of terminal or for indicating that the second type of terminal is allowed to access. In other words, the system information corresponding to the first type of terminal in the first SIB1 is used to indicate one of system information supporting the first type of terminal and system information allowing the first type of terminal to access or be present.

[0072] Furthermore, the SIBx may be understood as another SIB other than the second SIB1 in the newly added second SIB, and may be used to carry system information corresponding to the first type of terminal. The system information may indicate, explicitly or implicitly, at least one of whether the first cell supports the first type of terminal and whether the first cell allows the first type of terminal to access or be located. Here, the first cell is the terminal in which the first type of terminal is currently located.

[0073] The above SIBy may be understood as an SIB obtained by extending based on a conventional SIB after the first SIB1, for example, an SIB obtained by extending based on a certain SIB among conventional SIB2, SIB3, SIB4, SIBn, and this SIBy may be called SIB2-light, SIB3-light, SIB4-light, SIBn-light. SIBy includes system information required for a cell in which a first type of terminal is located, and this system information may indicate implicitly or explicitly at least one of whether the first cell supports the first type of terminal and whether the first cell allows the first type of terminal to access or reside.

[0074] Optionally, the system information corresponding to the first type of terminal in SIBx and SIBy is used to indicate system information required for accessing or camping on the cell in which the first type of terminal is located.

[0075] In a specific use case, if SIBx or SIBy indicates system information required for accessing or staying in the cell where the first type of terminal is located, the terminal may understand that the first cell supports the first type of terminal and allows the first type of terminal to access or stay, and can then perform the access or stay process. Of course, in another alternative implementation case, SIBx or SIBy may further include another indication identifier for indicating at least one of whether the first cell supports the first type of terminal and whether the first cell allows the first type of terminal to access or stay.

[0076] It should be noted that the values ​​of x and y may be indicated by some information elements (IEs) of a conventional SIB1 message.

[0077] According to the network-side access control method of the above embodiment of the present application, the network-side equipment can configure corresponding access control parameters for different types of terminals, for example, by configuring corresponding first access control parameters for a first type of terminal to perform access control, and configuring corresponding second access control parameters for a second type of terminal, so that different types of terminals can obtain corresponding access control parameters in the access control process, without affecting the access of other types of terminals after a large number of accesses by one type of terminal, and solving the problem in the prior art that the access control of another type of terminal is affected after a large number of accesses by all different types of terminals sharing one set of the same access control parameters.

[0078] It should be noted that in the access control method according to the embodiment of the present application, the execution body may be an access control device or a control module for executing the access control method in the access control device. In the embodiment of the present application, the execution of the access control method by the access control device is taken as an example to describe the access control device according to the embodiment of the present application.

[0079] The embodiment of the present application provides an access control device for a first type of terminal. FIG. 4 is a structural schematic diagram of the access control device of the embodiment of the present application. As shown in FIG. 4, the device includes: an acquisition module 42 for acquiring a first access control parameter different from a second access control parameter corresponding to a second type of terminal; and an access control module for performing access control based on the first access control parameter.
