[0025] The present application will be described below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other. Additionally, it should be noted that for the sake of description, only parts related to the present application rather than all structures are shown in the drawings.
[0026] In the NR system, unified access control (UAC) can be performed on terminals according to the access category or access identity of the terminal. For the access category, a total of 64 categories are defined, among which, Categories 0 to 8 can be applied to the access control of NR; for the access identity, a total of 16 categories are defined, among which, Categories 0 to 3 and 11 to 15 can be applied to the access control of NR.
[0027] Compared with other terminals in the NR system, the REDCAP terminal has a lower service priority and requires more bandwidth resources to obtain the same data rate. If the same access control method is used for both the REDCAP terminal and other terminals in the NR system, the REDCAP terminal will occupy more bandwidth resources, unable to ensure communication efficiency and the performance of the entire system, and the access of the REDCAP terminal will affect the communication quality of the deployed terminals.
[0028] In an embodiment of the present application, an access control method is provided, which can be applied to a first network node. The first network node is, for example, a user equipment (UE), including a REDCAP terminal. The first network node determines the target access control parameters according to the type of the terminal it belongs to, and determines whether to allow access accordingly, so as to implement access control for different types of terminals respectively, and improve the flexibility and reliability of access control.
[0029] Figure 1 A flowchart of an access control method provided for an embodiment is as Figure 1 shown. The method provided in this embodiment includes Step 110 and Step 120.
[0030] In Step 110, the target access control parameters are obtained according to the type of the terminal it belongs to.
[0031] In this embodiment, the terminals can be divided into REDCAP terminals and non-REDCAP terminals, and can also be divided into terminals that perform unified access control using the access control parameters of NR and terminals that perform access control using the access control parameters separately configured for REDCAP terminals, etc. The first network node obtains the corresponding target access control parameters according to the type of the terminal it belongs to, as the basis for access control, where the target access control parameters are used to indicate the access control information corresponding to the type of the terminal to which the first network node belongs, that is, to indicate whether the first network node of this terminal type is allowed to access. The target access control parameters corresponding to each terminal type can be configured by a second network node (such as a base station) and transmitted to the first network node.
[0032] In step 120, access control information is determined according to the target access control parameter, and the access control information includes allowed access or prohibited access.
[0033] In this embodiment, the first network node completes the access control check according to the obtained target access control parameter, that is, determines whether the first network node is allowed to access or prohibited from accessing. If access is allowed, the first network node initiates a random access in the target cell where it is currently located.
[0034] In one embodiment, the access control of the first network node is enabled in the following manner: the second network node configures indication information in the Master Information Block (MIB) indicating whether each cell allows access. For example, when the target cell where the first network node is located is indicated as the barred state, the first network node considers that access to the target cell is prohibited and does not need to continue reading the parameters related to access control, nor does it need to perform an access control check; when the target cell is indicated as allowing access, the first network node can continue to read the relevant configuration information in System Information Block (SIB) SIB1, complete the access control check according to the target access control parameter, etc. On this basis, if the access control information corresponding to the target access control parameter is allowed access, the first network node can initiate a random access in the target cell.
[0035] In one embodiment, the first network node is a REDCAP terminal. For the REDCAP terminal, there are the following two ways to enable the access control of the REDCAP terminal: the first is that the indication information configured by the second network node in the MIB also applies to the REDCAP terminal. The REDCAP terminal needs to first read the indication information, and then determine whether to further read the relevant configuration and target access control parameters and judge whether access is allowed according to whether the state indicated by the target cell is barred; the second is that additional indication information indicating whether access is allowed is added to the REDCAP terminal, and this indication information only takes effect when the target cell of NR is indicated as allowing access, that is, if the target cell of NR is indicated as the barred state, the REDCAP terminal also considers that the target cell is in the barred state, and if the target cell of NR is indicated as allowing access, it is further determined whether to further read the relevant configuration and target access control parameters and judge whether access is allowed according to whether the additional indication information is in the barred state.
[0036] In one embodiment, the R-E-D-C-A-P terminal is associated with the configuration of the target access control parameters related to the access control classification, which can be configured in an independent SIB message. For example, the newly introduced SIB message is SIB1-R-E-D-C-A-P. In this case, the R-E-D-C-A-P terminal needs to read SIB1-R-E-D-C-A-P for access control check. If access is allowed, it continues to read other SIB messages.
[0037] In one embodiment, it further includes:
[0038] Step 101: Determine the terminal type to which it belongs according to at least one of the terminal category information and the terminal capability information.
[0039] In this embodiment, the terminal type of the terminal can be determined according to the bandwidth capability of the first network node. For example, terminals supporting different bandwidths respectively correspond to different categories of capability-reduced terminals; or, it can also be directly determined according to the category of the capability-reduced terminal reported by the first network node.
[0040] In one embodiment, the number of target access control parameters corresponding to the first capability-reduced terminal and the second capability-reduced terminal can be the same or different.
[0041] In one embodiment, the terminal type includes a capability-reduced terminal type and a non-capability-reduced terminal type.
[0042] In this embodiment, the R-E-D-C-A-P terminal and the non-R-E-D-C-A-P terminal are distinguished and access control is performed separately. The target access control parameters and access control information corresponding to the R-E-D-C-A-P terminal can be the same as or different from those of the non-R-E-D-C-A-P terminal.
[0043] In one embodiment, the access control classification associated with the target access control parameters includes the reserved classification in the access control classification of NR.
[0044] In this embodiment, the access control classification associated with the target access control parameters includes the reserved classification in the Access Category of NR. When the first network node is a R-E-D-C-A-P terminal, the reserved classification in the Access Category of NR can be applied to the classification of the R-E-D-C-A-P terminal, that is, according to the reserved classification in the Access Category of NR, the same parameter configuration and definition are applied to the access control parameter configuration of the R-E-D-C-A-P terminal. For example, the reserved classification in the Access Category of NR includes Category 9 to 31, and Category 9 to 17 among them are used for the access control parameter configuration of the R-E-D-C-A-P terminal.
[0045] In one embodiment, the access control classification associated with the target access control parameter includes the used classification in the access control classification of NR.
[0046] In this embodiment, the access control classification associated with the target access control parameter includes the used classification in the Access Category of NR. When the first network node is a REDCAP terminal, the used classification in the Access Category of NR can be used for classifying the REDCAP terminal, and indication information can also be added to each used classification to indicate whether the REDCAP terminal is allowed to access.
[0047] In one embodiment, it further includes: Step 102: Obtain the n-bit indication information corresponding to the used classification, where the indication information is used to indicate the access control information corresponding to the used classification associated with the target access control parameter, and n is 1 or 2 or 3 or 4.
[0048] In this embodiment, when the first network node is a REDCAP terminal, Category 0-8 of NR is used to configure the target access control parameter of the REDCAP terminal, and n-bit indication information is added to Category 0-8 respectively, which is used to indicate whether the access control information corresponding to each terminal type is allowed to access or prohibited from accessing, or to indicate whether each terminal type has the same barred state as the Category of NR. Among them, the n-bit indication information is only applicable to the REDCAP terminal and has no effect on other terminals in NR.
[0049] In this embodiment, the used classification corresponds to the n-bit indication information, which is used to indicate the access control information corresponding to the used classification associated with the target access control parameter, and n is 1 or 2 or 3 or 4.
[0050] For example, for the existing classification, one category is separated, and 1-bit indication information is used to indicate whether the access control information corresponding to this category is allowed to access or prohibited from accessing, or to indicate whether the access control information corresponding to this category is the same as or different from the access control information of this category in NR. For example, when n = 1, if the value of the 1-bit indication information corresponding to the used classification to which the REDCAP terminal belongs is true, it means that the barred state corresponding to this used classification is the same as the barred state of this used classification in NR; if the value of this 1-bit indication information is not true, then the barred state corresponding to this used classification is different from the barred state of this used classification in NR.
[0051] For example, for existing classifications, two categories are separated, and 2-bit indication information is used to indicate that the access control information corresponding to these two categories is access allowed or access prohibited, or to indicate that the access control information corresponding to these two categories is the same as or different from the access control information of these two categories in NR.
[0052] For example, for existing classifications, three categories are separated, and 3-bit indication information is used to indicate that the access control information corresponding to these three categories is access allowed or access prohibited, or to indicate that the access control information corresponding to these three categories is the same as or different from the access control information of these three categories in NR.
[0053] For example, for existing classifications, four categories are separated, and 4-bit indication information is used to indicate that the access control information corresponding to these four categories is access allowed or access prohibited, or to indicate that the access control information corresponding to these four categories is the same as or different from the access control information of these four categories in NR.
[0054] In one embodiment, the access control classifications associated with the target access control parameters include access control classifications dedicated to terminals with predefined reduced capabilities.
[0055] In this embodiment, when the first network node is a REDCAP terminal, a dedicated access control classification is defined for the REDCAP terminal.
[0056] In one embodiment, the dedicated access control classification is defined as one of the following:
[0057] 1) The number of dedicated access control classifications is 64. The dedicated access control classifications include access control classifications for terminals with reduced capabilities, reserved access control classifications for terminals with reduced capabilities, and operator-defined access control classifications for terminals with reduced capabilities. For example, Categories 0 to 8 are types of REDCAP terminals, Categories 9 to 31 are reserved classifications for REDCAP terminals, and Categories 32 to 63 are operator-defined types for REDCAP terminals.
[0058] 2) The number of dedicated access control classifications is 32. The dedicated access control classifications include access control classifications for terminals with reduced capabilities and reserved access control classifications for terminals with reduced capabilities. For example, Categories 0 to 8 are types of REDCAP terminals, and Categories 9 to 31 are reserved classifications for REDCAP terminals.
[0059] 3) The number of dedicated access control classifications is 16. The dedicated access control classifications include the access control classification for terminals with reduced capabilities and the reserved classification for access control of terminals with reduced capabilities. For example, A Category 0 to 8 are the types of REDCAP terminals, and Category 9 to 15 are the reserved classifications for REDCAP terminals.
[0060] 4) The number of dedicated access control classifications is 9. The dedicated access control classifications include the access control classification for terminals with reduced capabilities. For example, Category 0 to 8 are the types of REDCAP terminals.
[0061] In one embodiment, the terminal types at least include a first type of terminal with reduced capabilities and a second type of terminal with reduced capabilities; wherein, the access control parameters corresponding to the first type of terminal with reduced capabilities are the same as the access control parameters used by NR terminals, and the second type of terminal with reduced capabilities corresponds to target access control parameters.
[0062] In this embodiment, the first network nodes at least include two types: the first REDCAP terminal and the second REDCAP terminal. Among them, the first REDCAP terminal follows the Access category of NR and performs access control checks according to the access control parameters and related configurations of NR; the second REDCAP terminal uses target access control parameters, and the target access control parameters are associated with newly introduced access control classifications. The second REDCAP terminal performs access control checks according to the newly introduced access control classifications. Among them, the newly introduced access control classifications can be reserved classifications, used classifications, or dedicated access control classifications in NR. In this case, the second network node needs to configure target access control parameters for each newly introduced access control classification of the REDCAP terminal, etc.
[0063] In one embodiment, the terminal types at least include a first type of terminal with reduced capabilities and a second type of terminal with reduced capabilities; the access control classification associated with the target access control parameters corresponding to the first type of terminal with reduced capabilities and the access control classification associated with the target access control parameters corresponding to the second type of terminal with reduced capabilities satisfy one of the following:
[0064] Both the access control classification associated with the target access control parameters corresponding to the first type of terminal with reduced capabilities and the access control classification associated with the target access control parameters corresponding to the second type of terminal with reduced capabilities are reserved classifications in the access control classifications of NR;
[0065] Both the access control classification associated with the target access control parameters corresponding to the first type of terminal with reduced capabilities and the access control classification associated with the target access control parameters corresponding to the second type of terminal with reduced capabilities are used classifications in the access control classifications of NR;
[0066] The access control classification associated with the target access control parameters for the terminal type with the first reduced capability and the access control classification associated with the target access control parameters for the terminal type with the second reduced capability are both access control classifications dedicated to predefined terminals with reduced capabilities.
[0067] In this embodiment, the first network node includes at least two types: the first REDCAP terminal and the second REDCAP terminal. Both the first REDCAP terminal and the second REDCAP terminal adopt the target access control parameters, and the target access control parameters are associated with newly introduced access control classifications (both are reserved classifications of access control classifications in NR, both are used classifications, or both are dedicated access control classifications), and access control checks are performed according to the newly introduced access control classifications. In this case, the second network node needs to configure the target access control parameters of the corresponding access control classifications for the first REDCAP terminal and the second REDCAP terminal respectively. Among them, the target access control parameters corresponding to the first REDCAP terminal and the second REDCAP terminal can be configured to be the same or different.
[0068] In this embodiment, the newly introduced access control classifications include:
[0069] 1) Reserved classifications of access control classifications in NR, Category9 - 17. The same access control parameter configurations and definitions are applied to the access control of the first REDCAP terminal and the second REDCAP terminal.
[0070] 2) Used classifications of access control classifications in NR, Category classifications 0 - 8. The used classifications in the Access Category of NR can be used for the classification of REDCAP terminals, and n - bit indication information can also be added to each used classification to indicate whether the first REDCAP terminal and the second REDCAP terminal are allowed to access.
[0071] 3) Access control classifications dedicated to predefined terminals with reduced capabilities, which are applied to the access control of the first REDCAP terminal and the second REDCAP terminal.
[0072] In one embodiment, the first network node includes at least two types: a first REDCAP terminal and a second REDCAP terminal. The first REDCAP terminal and the second REDCAP terminal respectively adopt target access control parameters, and the target access control parameters are associated with a newly introduced access control classification. The newly introduced access control classifications associated with the target access control parameters adopted by the first REDCAP terminal and the second REDCAP terminal can be different. The second network node needs to configure the target access control parameters for the first REDCAP terminal and the second REDCAP terminal respectively. The first REDCAP terminal and the second REDCAP terminal respectively obtain the target access control parameters according to their respective terminal types and perform access control checks.
[0073] In this embodiment, the newly introduced access control classifications include:
[0074] 1) A reserved classification of the access control classification of NR. Among them, the same access control parameter configuration and definition as that of Category 9-17 are applied to the access control of the first REDCAP terminal or the second REDCAP terminal.
[0075] 2) An occupied classification of the access control classification of NR. Category classifications 0-4 can be applied to the classification of the first REDCAP terminal, and Category classifications 5-8 can be applied to the classification of the second REDCAP terminal. n-bit indication information can also be added to each occupied classification to indicate whether the first REDCAP terminal and the second REDCAP terminal are allowed to access.
[0076] 3) A pre-defined access control classification dedicated to terminals with reduced capabilities, which is applied to the access control of the first REDCAP terminal or the second REDCAP terminal.
[0077] In one embodiment, step 120 further includes:
[0078] In the case where the target access control parameters are not obtained, determine the access control information according to the access control parameters of NR.
[0079] In this embodiment, when the first network node fails to obtain the target access control parameters (for example, the second network node does not configure the corresponding target access control parameters for the terminal classification to which it belongs), the access control information can be determined according to the existing access control parameters of NR, and access control can be performed accordingly to ensure the normal operation of the services of the first network node.
[0080] In one embodiment, it further includes:
[0081] Step 130: Determine candidate neighboring cells or neighboring cells to be measured according to the dedicated neighboring cell list of the terminal with reduced capabilities, or according to the support capabilities of each neighboring cell for the terminal with reduced capabilities in the neighboring cell list information;
[0082] Step 140: Reselect a target cell from the candidate neighboring cells or the neighboring cells to be measured.
[0083] In this embodiment, the first network node can determine candidate neighboring cells or neighboring cells to be measured for the REDCAP terminal, and perform cell reselection among the candidate neighboring cells or the neighboring cells to be measured, that is, reselect a neighboring cell with better communication quality as the new target cell and switch to the reselected target cell to initiate random access.
[0084] The second network node can configure a dedicated neighboring cell list for the REDCAP terminal. When the first network node is the REDCAP terminal, the candidate neighboring cells or the neighboring cells to be measured can be determined according to this neighboring cell list; or, the REDCAP terminal can also determine the candidate neighboring cells or the neighboring cells to be measured according to the support capabilities of each neighboring cell for the REDCAP terminal in the neighboring cell list information. In this case, the second network node can broadcast in the neighboring cell list information the indication information on whether each neighboring cell supports the REDCAP terminal.
[0085] In one embodiment, the support capabilities of each neighboring cell for the terminal with reduced capabilities are determined according to the first indication information in the same-frequency neighboring cell information of the third system information block SIB3, or according to the second indication information in the different-frequency neighboring cell information of the fourth system information block SIB4, or according to the same-frequency neighboring cell information or different-frequency neighboring cell information in the dedicated SIB of the terminal with reduced capabilities.
[0086] In this embodiment, the neighboring cell list information includes the support capabilities of each neighboring cell for the terminal with reduced capabilities. The second network nodes (such as base stations) interact with each other the support capabilities of each cell for the REDCAP terminal and record the support capabilities of each neighboring cell in the neighboring cell list for the REDCAP terminal. The second network node adds the configuration of the support capabilities of each neighboring cell for the REDCAP terminal in the neighboring cell list information, that is, the second network node broadcasts in the neighboring cell list information the indication information on whether each neighboring cell supports the REDCAP terminal. For example, add the first indication information in the same-frequency neighboring cell information (IntraFreqNeighCellInfo) in SIB3: SupportREDACAP ENUMERATED{true,faulse}; or add the second indication information in the different-frequency neighboring cell information (InterFreqNeighCellInfo) in SIB4: SupportREDACAP ENUMERATED{true,faulse}.
[0087] In one embodiment, the indication information of the support capability information of each neighboring cell for the REDCAP terminal may be configured by the second network node in SIB1, or may be configured in the downlink control information (DCI) that schedules SIB1.
[0088] In this embodiment, the second network node may indicate whether each neighboring cell supports the REDCAP terminal through the SIB1 message or the DCI that schedules SIB1. For example, it indicates whether each neighboring cell supports the REDCAP terminal through SupportREDACAP ENUMERATED {true, false}. If a neighboring cell supports the REDCAP terminal and is reselected by the first network node as a new target cell, then when the first network node is a REDCAP terminal, the first network node may further read the target access control parameters of the new target cell, determine the access control information, and initiate a random access in the new target cell when the access control information allows access.
[0089] In one embodiment, it further includes:
[0090] Step 150: Receive a paging message configuration message corresponding to the terminal type to which it belongs according to the terminal type to which it belongs;
[0091] Wherein, the paging message configuration message includes some paging-related parameters shared with NR terminals and some paging-related parameters specific to terminals with reduced capabilities.
[0092] In this embodiment, the second network node receives a paging message sent by the core network. If the paging message contains the support capability information for the REDCAP terminal and the support capability information indicates that the second network node supports the access of the REDCAP terminal, then the second network node may page the REDCAP terminal in the configured paging area. When the first network node is a REDCAP terminal, the first network node may receive a paging message configuration message according to the terminal type to which it belongs. The paging message configuration message includes some paging-related parameters shared with NR terminals and some paging-related parameters specific to terminals with reduced capabilities. Among them, the second network node configures a paging area dedicated to the REDCAP terminal or a shared paging area, and the paging message sent by the core network to the second network node includes the support capability information for the REDCAP terminal, that is, a REDCAP Capability cell is added to the message.
[0093] In one embodiment, some paging-related parameters shared with NR terminals include at least one of the following: the default paging cycle, the number of paging opportunities within a paging infinite frame.
[0094] In one embodiment, the proprietary partial paging related parameters include at least one of the following: Bandwidth Part (BWP), Physical Downlink Control Channel (PDCCH) paging search space.
[0095] In this embodiment, the partial paging related parameters shared with the NR terminal may include the default paging cycle (defaultPagingCycle) and the number (ns) of paging occasions within one paging infinite frame, and may also include the occasion of listening to the PDCCH at each paging occasion position, etc. The proprietary partial paging related parameters may include BWP and Paging Search Space of PDCCH, etc.
[0096] In one embodiment, for the above-mentioned partial paging related parameters shared with the NR terminal and the proprietary partial paging related parameters, the same configuration method as in the NR system may be adopted; or, the proprietary partial paging related parameters (BWP and PDCCH search space) may be configured independently; or, the partial paging related parameters shared with the NR terminal, BWP and PDCCH search space may all be configured independently.
[0097] The access control method of this embodiment improves the reliability and flexibility of access control by configuring target access control parameters for different terminal types. The target access control parameters are associated with different access control classifications and correspond to different access control information, serving as the basis for access control. For REDCAP terminals, access control can be performed independently, improving the utilization efficiency of bandwidth resources and avoiding the impact of the access of REDCAP terminals on the communication quality of the deployed terminals. In addition, cell reselection is also realized according to the support capability information of neighboring cells for REDCAP terminals, and paging of REDCAP terminals by the second network node is realized, further improving the reliability of REDCAP terminal access.
[0098] In the embodiment of the present application, an access control method is also provided, which can be applied to a second network node, and the second network node is, for example, a base station. It should be noted that in this embodiment, the operations performed by the second network node correspond to the operations performed by the first network node in the above embodiment. The technical details not described in detail in this embodiment can be referred to any of the above embodiments.
[0099] Figure 2 A flowchart of an access control method provided for another embodiment is as Figure 2 shown. The method provided in this embodiment includes step 210 and step 220.
[0100] In step 210, according to the terminal type, configure the target access control parameters corresponding to the terminal type, where the target access control parameters are used to indicate access control information, and the access control information includes allowed access or prohibited access.
[0101] In step 220, transmit the access control parameters.
[0102] In this embodiment, the second network node configures corresponding target access control parameters for different terminal types and transmits them to the first network node as the basis for access control of the first network node, so as to realize separate access control for different types of terminals and improve the flexibility and reliability of access control.
[0103] In one embodiment, the terminal type is configured according to at least one of terminal category information and terminal capability information.
[0104] In one embodiment, the terminal type includes a terminal type with reduced capabilities and a terminal type without reduced capabilities.
[0105] In one embodiment, the access control classification associated with the target access control parameters includes a reservation classification in the access control classification of NR.
[0106] In one embodiment, the access control classification associated with the target access control parameters includes an in-use classification in the access control classification of NR.
[0107] In one embodiment, it further includes:
[0108] Step 201: Configure the n-bit indication information corresponding to the in-use classification, where the indication information is used to indicate the access control information corresponding to the in-use classification corresponding to the target access control parameters, where n is 1 or 2 or 3 or 4.
[0109] In this embodiment, the second network node uses NR's Category 0 to 8 to configure the target access control parameters of REDCAP terminals, and adds n-bit indication information to Category 0 to 8 respectively, which is used to indicate whether the REDCAP terminals of this type have a barred state consistent with NR's Category. Among them, the n-bit indication information is only applicable to REDCAP terminals and has no effect on other terminals in NR. The n-bit indication information can be used to indicate that the access control information corresponding to each terminal type is allowed access or prohibited access, or to indicate whether each terminal type has a barred state consistent with NR's Category.
[0110] In one embodiment, the access control classification associated with the target access control parameter includes an access control classification dedicated to terminals with predefined reduced capabilities.
