Please refer to FIG. 1 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. As shown in FIG. 1 , the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: several UEs 11 and several base stations 12 .

The UE11 may be a device that provides voice and/or data connectivity to the user. The UE11 may communicate with one or more core networks via a Radio Access Network (RAN), and the UE11 may be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone) and an IoT-enabled UE. The UE's computer, for example, may be a stationary, portable, pocket-sized, hand-held, computer-built-in, or vehicle-mounted device. For example, a station (Station, STA), a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a mobile station (mobile), a remote station (remote station), an access point, a remote UE ( remote terminal), access UE (access terminal), user device (user terminal), user agent (user agent), user equipment (user device), or user UE (user equipment, UE). Alternatively, the UE11 may also be a device of an unmanned aerial vehicle. Alternatively, the UE 11 may also be an in-vehicle device, for example, a trip computer with a wireless communication function, or a wireless communication device connected to an external trip computer. Alternatively, the UE 11 may also be a roadside device, for example, may be a street light, a signal light, or other roadside device having a wireless communication function.

The base station 12 may be a network-side device in a wireless communication system. Wherein, the wireless communication system may be a fourth generation mobile communication (the 4th generation mobile communication, 4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; or, the wireless communication system may also be a 5G system, Also known as new radio (NR) system or 5G NR system. Alternatively, the wireless communication system may also be a next-generation system of the 5G system. Among them, the access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network, a new generation of radio access network). Alternatively, the MTC system.

The base station 12 may be an evolved base station (eNB) used in the 4G system. Alternatively, the base station 12 may also be a base station (gNB) that adopts a centralized distributed architecture in a 5G system. When the base station 12 adopts a centralized distributed architecture, it usually includes a centralized unit (central unit, CU) and at least two distributed units (distributed unit, DU). The centralized unit is provided with a protocol stack of a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control Protocol (Radio Link Control, RLC) layer, and a Media Access Control (Media Access Control, MAC) layer; distribution A physical (Physical, PHY) layer protocol stack is set in the unit, and the specific implementation manner of the base station 12 is not limited in this embodiment of the present disclosure.

A wireless connection can be established between the base station 12 and the UE 11 through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, such as The wireless air interface is a new air interface; alternatively, the wireless air interface may also be a wireless air interface based on a 5G next-generation mobile communication network technology standard.

In some embodiments, an E2E (End to End, end-to-end) connection may also be established between UE11. For example, V2V (vehicle to vehicle, vehicle-to-vehicle) communication, V2I (vehicle to Infrastructure, vehicle-to-roadside equipment) communication and V2P (vehicle to pedestrian, vehicle-to-person) communication in vehicle-to-everything (V2X) communication etc. scene.

In some embodiments, the above wireless communication system may further include a network management device 13 .

Several base stations 12 are respectively connected to the network management device 13 . Wherein, the network management device 13 may be a core network device in a wireless communication system, for example, the network management device 13 may be a mobility management entity (Mobility Management Entity) in an evolved packet core network (Evolved Packet Core, EPC). MME). Alternatively, the network management device may also be other core network devices, such as a serving gateway (Serving GateWay, SGW), a public data network gateway (Public Data Network GateWay, PGW), a policy and charging rules functional unit (Policy and Charging Rules) Function, PCRF) or home subscriber server (Home Subscriber Server, HSS), etc. The implementation form of the network management device 13 is not limited in this embodiment of the present disclosure.

According to the conclusion of NR access control (access barring) in R15, the structure of the existing access control (AC barring) parameters is for each public land mobile network (Public Land Mobile Network, PLMN), each access category, Each access identity is provided. The following table gives an example where the maximum number of PLMNs is 6, and the maximum numbers of access classes and access identities are 64 and 16, respectively.

Table 1 AC parameter example, (AC parameter can be understood as AC barring parameter).

In some cases, the access category may include at least one of the following:

Active signaling ("originating signaling");

emergency calls ("emergency calls");

Initiate a VoLTE voice call ("originating MMTEL voice");

initiate a VoLTE video call ("originating MMTEL video");

initiate an SMSo IP call ("originating SMSoIP");

Send SMS ("originating SMS");

called ("terminating calls");

calling("originating calls",);

Mobile caller for circuit fallback ("mobile originating CS fallback").

The access identities (Access identities) are a kind of user identities, which can be understood as attributes of the UE, for example, 0-9 are ordinary users, and 11-15 are high-priority users.

The definition of the AC barring parameter in the table is as follows. For non-special user IDs, the random number and the effective duration of the barring are defined; for special user ID services, bitmaps are used.

Therefore, the basic access control (AC barring check) process is to determine the access categories (Access categories) of the user equipment, obtain the AC barring parameters, and perform the AC barring check. The AC barring parameter is usually a random number for ordinary users (0-9), and a bitmap for high-priority users (11-15).

In one embodiment, the AC parameters will be defined by the SIB1 Instant RMSI.

In the current 3GPP standardization, a new terminal type called reduced capability UE or NR-lite or Redcap terminal for short is proposed. This type of equipment is similar to the IoT equipment in LTE. Based on 5G NR-lite, it usually needs to meet the following requirements: low cost and low complexity; the main application scenarios are factory sensors, or video surveillance and wearable devices. For the first two device types, it is usually a large and dense deployment in the network. In some cases, new access identities (Access identities) are introduced for specific terminal types of Redcap, such as the scenario of factory access identities, and possibly even more access identities (Access identities) for refined access identities types. ).

For Access identities, using the form of a bitmap will cause the network to change the AC parameters. For example, from the original 0->1 flip, after RedcapUE receives the system message update instruction, it will obtain SIB1 at the boundary of system message modification, and a large number of users will update at the same time at the system message modification boundary. Therefore, A large number of users initiate calls at the same time, resulting in a burst of traffic, which leads to network congestion. Therefore, this article is enhanced for the UAC of the Redcap type.

As shown in FIG. 2, an embodiment of the present disclosure provides a method for processing access control information, including:

S110: Deliver a system message block that independently carries the access control information of the UE of the preset type.

The method is applied to a base station, and the base station may be various types of base stations, for example, a macro base station, a small base station, or a micro base station.

In this embodiment of the present disclosure, the preset type of UE may be any specified UE, for example, the preset type of UE may include: Redcap UE.

The Redcap UE includes but is not limited to at least one of the following:

Smart home appliances, typical smart home appliances may include: smart water meters, smart electricity meters, smart gas meters and/or home monitoring equipment;

Industrial sensors, industrial sensing equipment including but not limited to: making monitoring equipment;

Video surveillance equipment, for example, monitors at various intersections;

Security equipment in a cell or factory, for example, video and/or audio monitors;

safety sensor;

Wearable device.

In order to distinguish the delivery of access control information of UEs other than predetermined types of UEs (ie, non-predetermined types of UEs), in this embodiment of the present disclosure, a system message block carrying its access control information is delivered to predetermined types of UEs alone. That is, the access control information of the UE of the predetermined type and the UE of the non-predetermined type is carried in different system message blocks and delivered.

For example, assuming that the access control information of UEs of non-predetermined types is uniformly carried in SIB1, the SIB1 does not carry the access control information of UEs of predetermined types, and the access control information of UEs of predetermined types is carried in other system message blocks or carried in in SIB1 sent on different time domains. In short, the SIB that carries the access control information of the UE of the predetermined type does not carry the access control information of the UE other than the UE of the predetermined type, thereby realizing the separation of the access control information of the UE of the predetermined type and the UE of the non-predetermined type. This further reduces the centralized influx access between the predetermined type UE and the non-predetermined type UE caused by the influx initiating access after the predetermined type UE receives the access control information, thereby reducing the congestion phenomenon of network access.

For example, if the predetermined type of UE is a Redcap UE, in S110, it is equivalent to: the base station will individually deliver a system message block for the Redcap UE, and the system message block carries the access control information of the Redcap UE; and for other UEs other than the Redcap UE For example, the access control information including but not limited to: enhanced Mobile Broadband (eMBB) is carried in a different system message block from that of the Redcap UE.

Here, the system message block carrying the access control information of the UE of the preset type alone can be understood as: the carried access control information belongs to the UE of the preset type, but does not include the access control information of the UE of the non-preset type.

The system message block carrying the access control information of the UE of the preset type and the system message block carrying the access control information of the UE of the non-preset type have at least one of the following similarities and differences:

1) The system message block carrying the access control information of the UE of the preset type and the system message block carrying the access control information of the UE of the non-preset type may adopt the same or different message structures.

2) The system message block carrying the access control information of the UE of the preset type and the system message block carrying the access control information of the UE of the non-preset type may be system message blocks sent on different time-frequency resources.

3) The system message block carrying the access control information of the UE of the preset type and the system message block carrying the access control information of the UE of the non-preset type may be system message blocks scheduled by different scheduling methods. For example, the scheduling method of the system message block carrying the access control information of the UE of a non-preset type may be: static scheduling; and the scheduling method of the system message block carrying the access control information of the UE of the preset type may be: dynamic scheduling or Semi-static scheduling.

4) The system message block carrying the access control information of the UE of the preset type and the system message block carrying the access control information of the UE of the non-preset type may adopt different transmission modes. For example, the system message block carrying the access control information of the UE of the preset type adopts the transmission mode corresponding to the enhanced coverage mode such as repeated transmission, while the system message block carrying the access control information of the UE of the non-preset type does not use repeated transmission or The transmission mode corresponding to the enhanced coverage mode, such as the enhanced coverage mode.

If the system message block that carries the access control information of the UE of the preset type and the system message block that carries the access control information of the UE of the non-preset type use the same message structure, there is no need to introduce a new information encapsulation structure, which can simplify the The difficulty of encoding and decoding information of base stations and base stations.

If the system message block carrying the access control information of the UE of the preset type and the system message block carrying the access control information of the UE of the non-preset type, at least one of the time-frequency resources, scheduling method and transmission method used in transmission If it is different, it is beneficial for the UE of the predetermined type and the UE of the non-predetermined type to determine whether to monitor or receive the corresponding system message block according to at least one of the scheduling method, the time-frequency resource and the transmission method, thereby reducing unnecessary UE side. The reception and/or decoding of system message blocks reduces the load rate of the UE.

The access control information includes: unified access control (Unified Access Control, UAC) information.

The access control information is used to perform access control when the Redcap UE has service-triggered access. The access control information may include: one or more access parameters.

The access parameter may include: an access factor. In this way, when the Redcap UE has service-triggered access, it can compare the size of the randomly generated random number with the access factor, and then determine whether to allow the Redcap according to the result of the size comparison. The UE initiates the call.

The access parameter may also include: indication information of the access level. In this way, after receiving the access control information, the Redcap UE can indicate the access level that allows access according to whether its own access level is the access control information. If so, determine to initiate the call, otherwise block the call. When a call is blocked, the initiating call can be prohibited within the time period of the prohibition timer.

In one embodiment, the access parameter further includes: the timing duration of the prohibit timer.

If the access control (Access Control, AC) decision of the call (that is, the access) is carried out according to the access parameters, and it is determined that the access is blocked, the UE is prevented from initiating random access within the timing range of the prohibition timer.

In one embodiment, the access control information includes:

Access type information, indicating one or more access types to which the UE of the predetermined type belongs;

and / or

Access identity information, indicating at least one access identity of the UE of the preset type.

In one embodiment, the access type for the preset type of UE includes: a dedicated access type of the preset type of UE.

In another embodiment, the access type of the preset type UE may further include: an existing access type in the related art, in this way, the preset type UE and non-preset type UE The same access type can be shared.

For example, one or more access types are configured for a predetermined type of UE, and the access type may be one or more newly introduced access types other than the access types (Access categories) provided in the related art. Assuming that the predetermined type of UE is a Redcap UE, the access type information carried in the access control information may be type information of one or more access types to which the Redcap UE belongs.

In one embodiment, all predetermined types of UEs may belong to the same access type.

In another embodiment, the access type information may also be used to indicate one or more access types to which different service types of the UE of the predetermined type belong.

Taking Redcap UE as the predetermined type of UE as an example, some Redcap UEs provide video surveillance services, some Redcap UEs collect process parameters for industrial production, some Redcap UEs perform security monitoring, and some Redcap UEs perform wearer physical indicators collection.

In one embodiment, among the preset UE types, UEs that provide different service types are all configured with dedicated access types, or only UEs that provide some service types are configured with dedicated access types.

For example, Redcap UEs that provide different service types can be configured with different access types. For example, both Redcap UEs for video surveillance and Redcap UEs for industrial processes are configured with their own transmission access types, and they belong to different access types.

For another example, only the UEs that provide video surveillance services in the Redcap UEs are configured with a separate dedicated access type, and the Redcap UEs that provide services of other service types belong to another same access type or multiple access types. The access type to which the Redcap UE providing services of other service types belongs may be one or more of the existing access types in the related art, or one or more newly introduced access types are introduced on the basis of the related art.

In one embodiment, the access control information further includes an access identifier. An access type may correspond to one or more access identities.

The access identities here may be: one or more access identities under the dedicated access type configured for the UE of the preset type, and/or, may also be under the existing access type in the related art One or more access identities.

In an embodiment, the preset type UE has one or more access types, and the access type is not further subdivided into multiple access identities, the access control information may carry the access type alone information.

In another embodiment, the preset type UE does not introduce one or more dedicated access types, but introduces one or more dedicated access types for the preset type UE under the existing access types in the related art access identifier, the access control information can carry the access type information alone.

In another embodiment, according to the configuration of the access type and/or the access identifier of the preset type, the access control information can carry the access type information and the access identifier information at the same time.

In some embodiments, UEs of different service types have different access types of the preset types of UEs.

The preset type of UE may be a type of UE with similarity in communication capabilities, but according to different business services provided, the preset type may also be divided into different sub-types, or a preset type of UE that handles different service types.

For example, all preset types of UEs can support reduced-capacity Redcap UEs with small bandwidth or small number of antennas.

For example, the service types supported by some preset types are: video surveillance service; the service types supported by some preset types of UEs are: the collection service of wearing the user's declared signs; some preset types of UEs are used for industrial Monitor, collect industrial data on industrial production and operations.

The services of these preset types of UEs are different, so it can be determined whether to configure the same or different access types according to their service requirements, so as to better perform access control and reduce centralized influx of access. Access control adapted to the service type of the UE.

In order to further preset the type of UE, after the system message carrying the access control information is issued, because the centralized access of the access triggered by the service data transmission is suspended, in the embodiment of the present disclosure, the preset type of different service types is used. The UE is configured with different access types. In this way, UEs of preset types will be accessed according to service types, thereby reducing network congestion caused by centralized influx of accesses.

In one embodiment, UEs of the preset types that provide different types of services in the same access type have different access identities.

In another embodiment, a unified access type may also be allocated to the preset type UE; or after multiple access types are allocated to the preset type UE, considering that the number of preset type UEs under different service types is different , it is also possible to set more access identities, so that the UE of the preset type can be divided into finer granularity.

In one embodiment, the method further includes:

For the preset types of UEs with different access identities, configure different call reasons;

and / or,

Different call reasons are configured for the preset types of UEs with different access types.

The preset type of UE may be a UE that performs a specific function. Assuming that the access identities are allocated according to the functions performed by the preset types of UEs, the reasons for triggering these calls are different. In order to facilitate the base station side to easily determine the service type of the preset type of UE or the function or access identifier or access type performed by the preset type of UE after receiving the access request of the preset type of UE, the access identifiers are different. And/or the preset type of access type UE is configured with different call reasons.

For example, the call reasons have different reason codes. The preset type UE will, according to its own access type, initiate a call request (access request) carrying a reason code corresponding to the access type when the access control decision determines that the access is allowed.

In one embodiment, the S110 may include:

broadcasting a system message block SIB1 that carries the access control information of the UE of the preset type alone;

and / or

A system message block SIBy carrying the access control information of the UE of the preset type is delivered, wherein the y is a positive integer other than 1.

The access control information of the UE of the preset type may be carried in SIB1 and/or SIBy. SIB1 is a broadcast system message block, while SIBy can broadcast, multicast or unicast system message blocks.

In short, regardless of whether the access control information of the preset type UE is carried in SIB1 or SIBy, the SIB1 and SIBy carrying the access control information of the preset type UE do not carry the access control information of the non-preset type UE.

SIB1 and/or SIBy are broadcast system message blocks. If the SIB1 carries the access control information of the preset type of UE, it does not carry the access control information of the non-preset type of UE, but it does not mean that it carries the preset type of UE. The system message block of the access control information does not carry other information content, but no longer carries access control information of a non-preset type.

In one embodiment, the access control information of all preset types of UEs may be uniformly carried in SIB1.

In another embodiment, the access control information of all preset types of UEs may be uniformly carried in SIBy.

In still another embodiment, the access control information of a part of the preset type UEs is carried in SIB1, and the access control information of a part of the preset type UEs is carried in SIBy. For example, the access control information of a preset type UE that provides multimedia information services such as video surveillance service and/or voice surveillance service is carried in SIB1, and the access control information of the remaining preset type UEs is carried in SIBy. Of course, this is only an example. In specific implementation, the access control information of some preset types of UEs may be carried in SIB1 according to the number of UEs of preset types providing services of different service types and/or data transmission requirements, and the remaining part of the access control information may be carried in SIB1. The access control information of the UE of the preset type is carried in the SIBy, so as to adapt the access control of the UE of the preset type that provides services of different service types, and balance the load in different time periods of the network to reduce congestion.

The value of y may be any positive integer other than 1, for example, 2, 3, 4, or 5, etc.

In some embodiments, the SIBy is a cell-level system message block.

The levels of system message blocks may include, but are not limited to, at least one of the following:

System message block at the Tracking Area (TA) level;

Cell-level system message block.

The system message block of the TA level has a scope of one TA, and the system message block is sent in all cells in the TA, and the group is used for the UE of the preset type in the TA.

The system message block at the cell level has a scope of action of a cell, the system message block is sent in the cell, and affects the UE of the preset type in the cell.

Setting SIBy as a cell-level system message block is convenient for each cell to configure SIBy transmission resources, scheduling methods and/or transmission methods according to its own capacity, load rate and/or data transmission requirements of UEs of preset types in the cell.

In an embodiment, the update notification of the SIBy is carried in the paging downlink control information DCI.

The update notification of the SIBy may be issued when the access control information of the UE of the preset type carried by the SIBy is updated.

In the embodiment of the present disclosure, the paging DCI is used to carry the update notification of the SIBy. At this time, the preset type UE in the idle state or the inactive state receives the paging DCI and performs paging related operations on the corresponding paging occasion.

In one embodiment, the update mode of the SIBy is an immediate update mode;

In the immediate update mode, the UE of the preset type immediately requests the updated SIBy after receiving the update notification.

If after the SIBy update notification is issued, the preset type UE immediately requests the updated SIBy after receiving the update notification. Since the timing of paging DCIs configured by different UEs is different, this is equivalent to issuing the update notification in batches to The preset type of UE can reduce the phenomenon that after the updated SIBy is issued, the preset type of UE is flooded into the access based on the internal service data to be transmitted, which reduces the network congestion again.

In some embodiments, the SIBy is an ondemand SIB obtained on demand.

If SIBy is on demanded SIB, only when the UE of the preset type sends an acquisition request, the system message block carrying the access control information of the preset type alone will be delivered.

For example, after the preset type UE receives the paging DCI carrying the SIBy update notification, if the immediate update mode is adopted, the preset type UE will immediately initiate an acquisition request, and the acquisition request is used to request the SIBy as the ondemand SIB , so as to obtain the updated access control information.

In some embodiments, the access control information of the UE of the preset type of the first type of service is carried in the SIB1;

The access control information of the UE of the preset type of the second type of service is carried in the SIBy.

In some embodiments, the first type of services here may be: services involving multimedia information, such as video surveillance and/or voice surveillance. The second type of business can be a sensor service business provided by various sensors, for example, industrial sensors and/or security sensors.

In some embodiments, the preset type UE of the second type of service is configured with multiple access identities.

For example, if the second type of service is the sensor service provided by the sensor, the access type corresponding to the second type of service can be subdivided into multiple access identifiers according to the type of the sensor and/or the parameters sensed by the sensor, and the access The introduction of the identity further disrupts the centralized access of the preset type UEs that provide the second type of business service.

In some embodiments, the access control information includes:

bitmap; wherein, the preset type UEs of multiple different access types correspond to different bits in the same bitmap; or, the preset type UEs of different access types have different the bitmap;

and / or,

Bitmap index, indicating the bitmap.

The bitmap may include N bits. The value of N can be any positive integer.

In some embodiments, multiple access type UEs correspond to the same bitmap. At this time, the UE of the preset type corresponds to one bitmap in total. At this time, the decoding of the system message block of the UE of the preset type and the delivery of the SIB of the base station are simplified, and the access control information only carries one bitmap.

The preset UEs of different access types have different bitmaps. If the preset UEs are configured with multiple access types, the preset UEs have a total of multiple bitmaps. At this time, priority can be given to the access control. The information carries the bitmap index alone, or simultaneously carries the bitmap and the bitmap index of the carried bitmap. In some embodiments, UEs of different access types have different bitmaps, that is, the UE of the preset type has M access types, and the UE of the preset type has M bitmaps as a whole. Any bitmap can contain one or more bits.

For example, some access types have subdivision access identifiers, and the bitmap corresponding to this access type contains at least a plurality of bits, wherein at least one bit corresponds to an access identifier.

For another example, if there is no subdivision access identifier under some access types, the number of bits included in the bitmap corresponding to this access type may be only one.

The bitmap index may be: identification information of the bitmap.

In some embodiments, all bitmaps may be delivered to the UE in advance, or the UE may acquire bitmaps in advance according to a communication protocol or other means, and these bitmaps are also configured with bitmap indexes. In this way, the access control information carries the bitmap index. After the preset type UE receives the bitmap index, it finds the bitmap stored locally and corresponding to the received bitmap index, and performs its own access according to the bitmap. access control judgment.

If the bitmap contains a large number of bits and the number of bitmaps is relatively small, if the access control information carries the bitmap index alone, the bits consumed by the access control information can be reduced, thereby reducing the number of bits corresponding to the SIB. overhead.

In this embodiment of the present disclosure, the access control information may individually carry the updated bitmap, or the bitmap index of the updated bitmap that takes effect, and may also carry the bitmap and the bitmap index at the same time.

In this embodiment of the present disclosure, bits in the bitmap have a corresponding relationship with corresponding access types and/or access identifiers.

In an embodiment, different bits in the bitmap of the UE of the preset type of the access type correspond to the UE of the preset type of different access identities. For example, one access type is subdivided into S access identifiers, and if one access identifier corresponds to 1 bit, the bitmap contains S bits. The 1-bit values of "0" and "1" can be used to indicate that access is allowed or blocked, respectively.

In response to adopting the first configuration manner, the access control information includes:

the bitmap;

The bitmap index indicates the bitmap carried by the access control information, and has a corresponding relationship with an access type and/or an access identifier.

In some cases, not all the access control information of the UEs of the preset types are updated, that is, they are updated with some bitmaps of the UEs of the preset types. How to inform the preset type UE of the access type and/or access identifier corresponding to the bitmap carried in the current access control information. In this case, the access control information not only carries the bitmap, but also indicates the bitmap index of the bitmap carried by the access control information.

In the first configuration mode, it is equivalent to the access control information, and the bitmap index of the bitmap is explicitly indicated by the dominant bit.

In another embodiment, in response to adopting the second configuration manner, the access control information includes: a plurality of bitmaps arranged according to a preset, wherein the preset arrangement of the bitmap is related to the bitmap The access types and/or access identifiers described in the figure correspond.

In this embodiment of the present disclosure, both the base station and the UE of the preset type may pre-arrange the order of the multiple bitmaps. In this case, the number and arrangement of bitmaps delivered each time the access control information remains unchanged. If the bit value of the bitmap corresponding to the updated access control information is changed from the previous bitmap, and the bit value of the bitmap corresponding to no updated access control information is changed from the previous bitmap The sent bitmap has not changed.

In this way, the bitmap index does not need to be carried in the access control information, so no further bit overhead is generated due to the bitmap index.

In a specific implementation process, according to the number of bitmaps and/or the number of bits contained in a single bitmap, the access control information can be delivered in the first configuration mode or the second configuration mode.

For example, when the number of bitmaps is less than the number threshold and/or the total bit overhead of all the bitmaps is less than the bit number threshold, the second configuration mode may be preferentially adopted.

For another example, when the number of bitmaps exceeds the number threshold or the total bit overhead of all bitmaps exceeds the bit number threshold, the first configuration mode may be preferentially adopted.

In the embodiments of the present disclosure, multiple configuration modes of the access control information are provided, so that it is convenient to select a configuration mode suitable for the current scenario according to the current requirements.
