Referring to fig. 1, a schematic structural diagram of a wireless communication system according to an embodiment of the disclosure is shown. As shown in fig. 1, the wireless communication system is a communication system based on a cellular mobile communication technology, and may include: a number of UEs 11 and a number of base stations 12.

Wherein UE11 may be a device that provides voice and/or data connectivity to a user. The UE11 may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), and the UE11 may be an internet of things UE such as a sensor device, a mobile phone (or "cellular" phone) and a computer with an internet of things UE, for example, a fixed, portable, pocket, hand-held, computer-built-in or vehicle-mounted device. Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile Station), mobile Station (mobile), remote Station (remote Station), access point, remote UE (remote terminal), access UE (access terminal), user terminal, user agent (user agent), user device (user equipment), or user UE (UE). Alternatively, the UE11 may be an unmanned aerial vehicle device. Alternatively, the UE11 may be a vehicle-mounted device, for example, a laptop with a wireless communication function, or a wireless communication device externally connected to the laptop. Alternatively, the UE11 may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices 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 technology (the 4th generation mobile communication,4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; alternatively, the wireless communication system may be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may 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, new Generation radio access network). Or, an MTC system.

Wherein the base station 12 may be an evolved base station (eNB) employed in a 4G system. Alternatively, the base station 12 may be a base station (gNB) in a 5G system employing a centralized and distributed architecture. When the base station 12 employs a centralized and distributed architecture, it typically includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A protocol stack of a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a medium access control (Media Access Control, MAC) layer is provided in the centralized unit; a Physical (PHY) layer protocol stack is provided in the distribution unit, and the specific implementation of the base station 12 is not limited by the embodiment of the present disclosure.

A radio connection may be established between the base station 12 and the UE11 over a radio air interface. In various embodiments, the wireless air interface is a fourth generation mobile communication network technology (4G) standard-based wireless air interface; or, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G-based technology standard of a next generation mobile communication network.

In some embodiments, an E2E (End to End) connection may also be established between UEs 11. Such as V2V (vehicle to vehicle, vehicle-to-vehicle) communications, V2I (vehicle to Infrastructure, vehicle-to-road side equipment) communications, and V2P (vehicle to pedestrian, vehicle-to-person) communications among internet of vehicles communications (vehicle to everything, V2X).

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

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

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

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

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

active signaling ("originating signalling");

emergency calls);

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

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

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

sending a short message ("registration SMS");

called ("terminating calls");

caller ("originating calls");

a mobile caller ("mobile originating CS fallback") with circuit fallback.

The access identifier (Access identities), i.e. one of the user identities, can then be understood as the UE's properties, e.g. 0-9 for normal users and 11-15 for high priority users.

Definition of the AC barren parameters in the table is shown below, wherein the random number and barren effective duration are defined for non-special user identification; and the service of special user mark adopts bitmap form.

The basic access control (AC barreng check) procedure is to determine the access type (Access categories) of the ue, obtain the AC barreng parameters, and perform the AC barreng check. The AC barreng parameter typically uses random numbers for normal users (0-9) and bitmap form for high priority users (11-15).

In one embodiment, the AC parameters will be defined by in SIB1, i.e., generic RMSI.

In the current 3GPP standardization, a new terminal type is proposed, called capability reduction (Reduced capability) UE, or simply NR-lite or Redcap terminal. The equipment is similar to the equipment of the Internet of things in LTE, and the following requirements are met based on the general requirement in 5G NR-lite: low cost and low complexity; the main application scenario is a factory sensor (sensor), or a video monitoring and wearable device. For the former two device types, there is typically a large number of dense deployments in the network. In some cases, a new access identity is introduced for a particular terminal type of Redcap, such as the context of a factory access identity (Access identities), and possibly even more access identities for a refined access identity type (Access identities).

For the access identity (Access identities) in the form of a bit map (bitmap) this would result in but the network would have changed for the AC parameters. For example, when the redcall receives the indication of updating the system message from the original 0- >1, SIB1 is acquired at the boundary of system message modification, and a large number of users update at the boundary of system message modification at the same time, so that a large number of users initiate calls at the same time to cause traffic burst, thereby causing congestion of the network. The enhancement is thus made herein, namely for a readcap type UAC.

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

s110: and issuing a system message block which independently carries access control information of the UE of the preset type.

The method is applied to a base station, which may be various types of base stations, such as macro base stations, small base stations, or micro base stations.

In the embodiment of the present disclosure, the preset type UE may be any UE specified, for example, the preset type UE may include: and (3) a Redcap UE.

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

smart home devices, a typical smart home device may include: intelligent water meter, intelligent electric meter, intelligent gas meter and/or home monitoring equipment;

Industrial sensors, industrial sensing devices include, but are not limited to: manufacturing monitoring equipment;

video monitoring devices, such as monitors for various intersections;

security devices, e.g., video and/or audio monitors, of a cell or factory floor;

a safety sensor;

a wearable device.

In order to distinguish the issue of access control information for UEs other than the predetermined type of UE (i.e., non-predetermined type of UE), in embodiments of the present disclosure, the system message block carrying its access control information may be issued for the predetermined type of UE alone. I.e. the access control information of the UE of the predetermined type and the UE of the non-predetermined type are carried in different system message blocks for transmission.

For example, assuming that access control information of a non-predetermined type UE is uniformly carried in SIB1, the SIB1 does not carry access control information of a predetermined type UE, which is carried in other system message blocks or SIB1 transmitted on a different time domain. In short, the SIB carrying the access control information of the UE of the preset type does not carry the access control information of the UE other than the UE of the preset type, so that the issuing separation of the access control information of the UE of the preset type and the UE of the non-preset type is realized, and the centralized inrush access between the UE of the preset type and the UE of the non-preset type caused by the inrush initiation access after the UE of the preset type receives the access control information is reduced, and the congestion phenomenon of network access is reduced.

For example, if the predetermined type UE is redcam, in S110, this corresponds to: the base station can independently issue a system message block aiming at the Redcap UE, wherein the system message block carries access control information of the Redcap UE; and for other UEs than redcast, for example, including but not limited to: the access control information enhancing the mobile bandwidth (enhanced Mobile Broadband, eMBB) is carried in a different system message block than the Redcap UE.

The system message block that separately carries the access control information of the UE of the preset type can be understood as: all the carried access control information belongs to the preset type UE, and the access control information of the UE with the non-preset type is not contained.

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 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 the 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 can be the system message blocks which are scheduled in different scheduling modes. For example, the scheduling manner of the system message block carrying the access control information of the non-preset type UE may be: static scheduling; the scheduling manner 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) Different transmission modes can be adopted for 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. For example, the system message block carrying the access control information of the UE of the preset type adopts a 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 adopt a transmission mode corresponding to the enhanced coverage mode such as repeated transmission or enhanced coverage mode.

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 adopt the same message structure, a new information packaging structure is not required to be introduced, and the difficulty of information coding and decoding of the base station and the base station can be simplified.

If the system message block carrying the access control information of the preset type UE is different from the system message block carrying the access control information of the non-preset type UE, at least one of time-frequency resources, a scheduling mode and a transmission mode used in transmission is different, the method is beneficial to the UE of the preset type and the UE of the non-preset type, and whether the corresponding system message block needs to be monitored or received is determined according to at least one of the scheduling mode, the time-frequency resources and the transmission mode, so that unnecessary system message blocks on the UE side are reduced in receiving and/or decoding, and the load rate of the UE is reduced.

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

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

The access parameters may include: and the access factor is used for comparing the random number generated randomly with the access factor when the Redcap UE has service triggering access, and determining whether to allow the Redcap UE to initiate a call according to the result of the comparison.

The access parameters may also include: the indication information of the access class, so after the Redcap UE receives the access control information, the Redcap UE can determine to initiate a call according to whether the access class of the Redcap UE is the access class of the access control information, which is allowed to be accessed, if so, the Redcap UE blocks the call. When blocking a call, initiating a call may be prohibited for the duration of the prohibit timer.

In one embodiment, the access parameters further include: the timing duration of the timer is disabled.

If the Access Control (AC) decision of the call (i.e. Access) is made according to the Access parameter, it is determined that the Access is blocked, and the UE is prevented from initiating random Access within the timing time range of the prohibit timer.

In one embodiment, the access control information includes:

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

and/or

And the access identification information indicates at least one access identification of the UE of the preset type.

In one embodiment, the access type for the preset type UE includes: and the exclusive access type of the preset type UE.

In another embodiment, the access type for the preset type UE may further include: the access types existing in the related art, in this way, the preset type UE and the non-preset type UE may share the same access type.

For example, one or more Access types are configured for a predetermined type UE, and the Access type may be one or more Access types newly introduced other than an Access type (Access category) provided in the related art. Assuming that the predetermined type 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 UEs of a predetermined type may belong to the same access type.

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

Taking the Recap UE as the preset type of UE as an example, some Recap UEs provide video monitoring service, some Recap UEs collect process parameters of industrial production, some Recap UEs conduct security monitoring, and some Recap UEs collect body indexes of a wearer.

In one embodiment, all UEs providing different service types in the preset type UEs are configured with dedicated access types, or only UEs providing part of service types may be configured with dedicated access types.

For example, a Redcap UE providing different traffic types may be configured with different access types. For example, both the Redcap UE for video monitoring and the Redcap UE for industrial processing are configured with access types for their own transmissions and belong to different access types.

For another example, only the UE providing the video monitoring service among the Redcap UEs is configured with a separate dedicated access type, and the Redcap UEs providing the service of other traffic types belong to another same access type or multiple access types. The access type to which the Redcap UE providing the other traffic type service 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 comprises an access identification. One access type may correspond to one or more access identities.

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

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

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

In another embodiment, the access control information may simultaneously carry the access type information and the access identification information according to a preset type of access type and/or configuration of the access identification.

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

The preset type UEs may be UEs of a type having a similarity in communication capability, but the preset types may be divided into different sub-categories according to different provided service, or the preset type UEs of different service types may be processed.

For example, the preset type of UE may support a reduced capability Redcap UE with a small bandwidth or a small number of antennas.

For example, some preset types support the service types: video monitoring service; the service types supported by some preset types of UEs are: wearing collection business of declaration sign of the user; still other preset types of UEs are used for industrial monitoring, collected industrial data for industrial production and operation.

The services of the preset type UE are different, so that whether the same or different access types are configured can be determined according to the service requirements of the preset type UE, and access control which is matched with the service types of the preset type UE is provided while the access control is better performed to reduce centralized inrush access.

In order to further suspend centralized access of access triggered by service data transmission after the system message carrying the access control information is issued by the preset type UE, in the embodiment of the present disclosure, different access types are configured for the preset type UE of different service types. Thus, the UE of the preset type can be accessed according to the service type, so that network congestion caused by centralized inrush access is reduced.

In one embodiment, the access identities of the UEs of the preset types providing different types of services in the same access type are different.

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

In one embodiment, the method further comprises:

different call reasons are configured for the preset type UE with different access identifiers;

and/or the number of the groups of groups,

different call reasons are configured for the preset type UEs having different access types.

The preset type of UE may be a UE performing a specific function. The reason for triggering these originating calls is different, provided that the access identities are assigned according to the functions performed by the pre-set type of UE. In order to facilitate the base station side to simply and conveniently determine the service type of the preset type UE or the function or the access identifier or the access type executed by the preset type UE after receiving the access request of the preset type UE, different call reasons are configured for the preset type UE with different access identifiers and/or access types.

For example, the call cause has a different cause code. And the UE of the preset type initiates a call request (access request) carrying a reason code corresponding to the access type according to the access type of the UE, when the access control decision determines that the access is allowed.

In one embodiment, the S110 may include:

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

and/or

And issuing a system message block SIBy which independently carries access control information of the UE of the preset type, wherein y is not a positive integer of 1.

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

In short, regardless of whether the access control information of the preset type UE is carried in SIB1 or SIBy, 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 UE of the preset type, the SIB1 does not carry the access control information of the UE of the non-preset type, but does not indicate that the system message block carrying the access control information of the UE of the preset type does not carry other information content, and only does not carry the access control information of the non-preset type any more.

In one embodiment, the access control information of all UEs of the preset type may be uniformly carried in SIB 1.

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

In yet another embodiment, access control information of a part of UEs of the preset type is carried in SIB1, and access control information of a part of UEs of the preset type is carried in SIBy. For example, access control information of a preset type UE providing a multimedia information service such as a video monitoring service and/or a voice monitoring service is carried in SIB1, and access control information of the remaining preset type UE is carried in SIBy. Of course, this is merely an example, and in a specific implementation, according to the number of UEs providing different service types for the preset type UEs and/or the data transmission requirement, the access control information of part of the preset type UEs may be carried in SIB1, and the access control information of the rest of the preset type UEs may be carried in SIBy, so as to adapt the access control of the preset type UEs providing different service types, and balance the loads in different time periods of the network, and reduce congestion.

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

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

The level of the system message block may include, but is not limited to, at least one of:

tracking Area (TA) level system message blocks;

cell-level system message block.

And the system message block of the TA level has an action range of one TA, and 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 the action range of one cell, and is sent in the cell and acts as the UE of the preset type in the cell.

And setting SIBy as a system message block at a cell level, so that each cell can conveniently configure transmission resources, a scheduling mode, a transmission mode and the like of the SIBy according to the capacity and the load rate of the cell and/or the data transmission requirement of the UE of the preset type in the cell.

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

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

In the embodiment of the disclosure, the update notification of the SIBy is carried by paging (DCI). At this time, the paging DCI received by the idle or inactive UE of the preset type may perform paging related operations on the corresponding paging occasion.

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

and in the immediate updating mode, the preset type UE immediately requests the updated SIBy after receiving the updating notification.

If the update notification of the SIBy is issued, after the preset type UE receives the update notification, the updated SIBy is immediately requested, and due to different paging DCI occasions configured by different UEs, the update notification is issued to the preset type UE in batches, so that the phenomenon that the preset type UE is accessed based on the internal service data to be transmitted after the update SIBy is issued is reduced, and the network congestion is reduced again.

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

If SIBy is an on demander SIB, only when the UE of the preset type sends an acquisition request, the system message block which independently carries the access control information of the preset type is issued.

For example, after receiving paging DCI carrying an update notification of SIBy, if an immediate update manner is adopted, the preset type UE immediately initiates an acquisition request, where the acquisition request is used to request the SIBy as an ondemand SIB, so as to obtain updated access control information.

In some embodiments, the access control information of the preset type UE of the first type of service is carried in the SIB 1;

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, here the first type of traffic may be: services involving multimedia information, such as video monitoring and/or voice monitoring. The second type of service may be a sensor service provided by various sensors, such as industrial sensors and/or security sensors.

In some embodiments, the preset-type UE of the second class of service is configured with a plurality of access identities.

For example, the second type of service is a sensor service provided by a sensor, and according to the type of the sensor and/or the parameter sensed by the sensor, the access type corresponding to the second type of service may be subdivided into a plurality of access identifiers, and the centralized access of the preset type of UE providing the service of the second type of service may be further scattered by introducing the access identifier.

In some embodiments, the access control information comprises:

a bit map; wherein the preset types of UEs of a plurality of different access types correspond to different bits in the same bit map; or, the preset type UE with different access types has different bit maps;

And/or the number of the groups of groups,

a bit map index indicating bit maps.

The bit map may comprise 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 preset type UEs correspond to one bit map in total. At this time, decoding of the system message block of the preset type UE and issuing of SIB of the base station are simplified, and the access control information only carries one bit map.

The preset UEs of different access types have different bit bitmaps, and if the preset type UE is configured with a plurality of access types, the preset type UE has a plurality of bit bitmaps in total, and at this time, it may be prioritized that the bit bitmap index is carried in the access control information alone or the bit bitmap index of the bit bitmap and the bit bitmap index carried at the same time. In some embodiments, UEs of different access types have different bitmaps, i.e. a preset type UE has M access types, and the preset type UE has M bitmaps as a whole. Any one bit map may contain one or more bits.

For example, if there are sub-divided access identities under some access types, the bit map corresponding to such access types contains at least a plurality of bits, wherein at least one bit corresponds to one access identity.

For another example, if there are access types for which access identities are not subdivided, the bit map corresponding to such access types may contain only 1 bit.

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

In some embodiments, all bit maps may be issued to the UE in advance, or the UE may have obtained bit maps in advance according to a communication protocol or the like, which are also configured with bit map indexes. In this way, the access control information carries the bit bitmap index, after the preset type UE receives the bit bitmap index, the bit bitmap corresponding to the received bit bitmap index is searched for in local storage, and the access control decision of the UE is carried out according to the bit bitmap.

If the bit bitmap contains more bits and the bit bitmap has fewer bits, the bit consumed by the access control information can be reduced if the access control information alone carries the bit bitmap index, thereby reducing the bit overhead of the corresponding SIB.

In the embodiment of the disclosure, the access control information may independently carry the updated bit map, or independently carry the bit map index of the bit map that is effective after being updated, and may also simultaneously carry the bit map and the bit map index.

In the embodiment of the disclosure, the bits in the bit map have a corresponding relationship with the corresponding access type and/or access identifier.

In one embodiment, different bits within the bit map of the pre-set type UE of one of the access types correspond to the pre-set type UE of a different access identity. For example, one access type is subdivided into S access identities, and if one access identity corresponds to 1 bit, the bit map contains S bits. The 1-bit values "0" and "1" may be used to indicate that access is allowed or blocked, respectively.

The access control information includes:

the bit map;

the bit map index indicates the bit map carried by the access control information and has a corresponding relation with an access type and/or an access identifier.

In some cases, not all access control information of the preset type UE is updated, i.e. updated with part of the bitmap of the preset type UE. How to inform the preset type UE of the access type and/or the access identifier corresponding to the bit map carried by the current access control information. In this case, the access control information, in addition to carrying the bit map, indicates the bit map index of the bit map it carries.

In the first configuration, the bit map index of the bit map is indicated by dominant bit dominance in the access control information.

In another embodiment, the access control information includes, in response to adopting the second configuration,: and a plurality of bit maps arranged according to a preset, wherein the preset arrangement of the bit maps corresponds to the access type and/or the access identifier of the bit maps.

In the embodiment of the present disclosure, the base station and the UE of the preset type may both pre-arrange the plurality of bit maps in order. In this case, the number and arrangement of bitmaps issued by the access control information are unchanged each time. If the bit value of the bit map corresponding to the updated access control information is changed relative to the bit map transmitted in the previous time, the bit value of the bit map corresponding to the access control information which is not updated is not changed relative to the bit map transmitted in the previous time.

In this way, the access control information does not need to carry the bit map index, so that no further bit overhead is generated due to the bit map index.

In a specific implementation process, the access control information may be selectively issued in a first configuration mode or a second configuration mode according to the number of bit maps and/or the number of bits contained in a single bit map.

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

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

In the embodiment of the disclosure, various configuration modes of access control information are provided, so that the configuration mode of a proper current scene can be conveniently selected according to current requirements.
