It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0053] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0054] Terminal-side UAC

[0055] When a terminal needs to access a network system, it performs an access control check to determine whether access is permitted. This access control check is performed on the access attempt. The access attempt is triggered by a preset event. When the terminal's Non-Access Stratum (NAS) detects the preset event, the NAS needs to map the request type to one or more access identities (AIs) and an access category (AC). Then, the Access Stratum (AS) performs an access control check on the request based on the determined access identity and access category.

[0056] The NAS layer determines the requested access identifier and access category by examining the reason for access, the type of service requested, and the terminal's configuration file (including terminal configuration) based on a set of access identifiers and access categories defined in a protocol (e.g., 3GPP TS22.261). The set of access identifiers and access categories defined by the protocol includes: a) a set of standardized access identifiers; b) a set of standardized access categories; and c) a set of operator-defined access categories (if available).

[0057] In 5G Mobility Management Connected (5GMM-CONNECTED) mode, when RRC is inactive, the UE will provide the appropriate access identifier to the lower layer (access layer) in order to enable the lower layer (access layer) to perform access prohibition checks on access attempts.

[0058] In related technologies, if the terminal (UE) is in an idle state and the access attempt is allowed, the terminal initiates an initial NAS message; if the UE is in an idle state and the access attempt is barred, the UE does not initiate an initial NAS message. Specifically, for IP Multimedia Subsystem (IMS) services, the terminal may wish to select an Evolved UMTS Terrestrial Radio Access (E-UTRA) cell connected to the Evolved Packet Core (EPC). If the terminal is in a connected state and the access attempt is allowed, the UE initiates corresponding procedures, such as establishing / modifying a PDU session or requesting policies; if the UE is in a connected state and the access attempt is barred, the UE does not initiate corresponding procedures until the barring ends.

[0059] Access network side UAC

[0060] The access network supports overload and access control functions, such as Random Access Channel (RACH) backoff, RRC connection rejection, RRC connection release, and UE-based access prohibition mechanisms.

[0061] In related technologies, User-Agent Control (UAC) is not implemented without considering data priority or device status. When a large number of terminals simultaneously request data transmission (initiating access attempts), applying equal access control to various types of data (e.g., different data packets of the same type of service) can lead to data congestion and reduce the success rate of data transmission. In this embodiment, the specific setting of data priority information can be understood as different data from different terminals having different priorities. For example, data transmission can be in a screen-on state (e.g., a user opens an application requesting a service) or a screen-off state (e.g., some applications may need to send heartbeat packets). However, data transmission requests in the screen-on state originate from users (e.g., a user opens an application requesting a service), therefore, terminals in the screen-on state have a higher priority than terminals in the screen-off state when transmitting data.

[0062] The access control method, device, terminal, network-side equipment, medium, and product provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0063] Referring to Figure 2, which is a flowchart of an access control method provided in an embodiment of this application for a terminal, the method includes the following steps:

[0064] Step 201: The terminal performs access control based on the first information; wherein the first information includes at least one of the following:

[0065] The primary data priority information;

[0066] The terminal's screen status.

[0067] In this embodiment, the aforementioned first data can be understood as data to be transmitted, data that triggers an access attempt, or data that triggers access control. For example, the aforementioned first data can be a user uplink data packet, a user uplink data packet sent when the terminal screen is off, or a user uplink data packet sent when the terminal screen is on. The above are merely examples of first data and are not intended to limit the scope of the first data.

[0068] In this embodiment, the data packet has at least one priority information. The priority information indicates the importance of the data (e.g., the data packet). For example, in some embodiments, the priority of a UE data packet in a screen-on state is higher than the priority of a UE data packet in a screen-off state. In some embodiments, the priority of a data packet from UE A is higher than the priority of a data packet from UE B. In some embodiments, the priority of an application A data packet is higher than the priority of an application B data packet. The priority information can be relative to the network side (i.e., comparing the priorities of data packets from different UEs) or relative to the UE itself (i.e., comparing the priorities of different data packets from the UE itself). In some embodiments, the priority information can be expressed as weight information; for example, the weight information can be 0.1, 0.2, 0.3, ..., 1, where 1 has the highest weight and 0.1 has the lowest weight. In some embodiments, the priority information can be expressed as a priority type; for example, the priority type can be high / low or high / medium / low, etc. (depending on how many priority levels need to be divided, for example, high / medium / low corresponds to 3 priority levels, or it can be a more granular priority level division, for example, N different priorities, N>3; this embodiment does not limit this). In other implementations, taking a two-priority configuration as an example, it can be described as high-priority data packets and low-priority data packets, or as data packets (i.e., ordinary data packets) and low-priority data packets (i.e., described based on ordinary data packets, where ordinary data packets refer to data packets before priority distinction). It is understood that by referring to ordinary data packets for priority description, the number of priorities introduced can be reduced when there are few priority levels, while maintaining consistency with traditional UEs. This can be understood as a UE that cannot recognize priority information (traditional UE) determining the data packet priority as ordinary data packets according to the transmission method of related technologies, while a UE that can recognize priorities (enhanced UE) will consider low-priority data packets, ensuring that the access network device can serve both traditional and enhanced UEs. Taking a three-priority configuration as an example, it can be described as high-priority data packets, medium-priority data packets, and low-priority data packets, or as high-priority data packets, data packets, and low-priority data packets (i.e., described based on ordinary data packets).

[0069] In this embodiment of the application, the target priority information mentioned above refers to the priority information corresponding to the first data. For example, the first data is user uplink data sent when the terminal screen is off, and the corresponding target priority information can be the first priority (or described as "data packet" or "normal data packet"), or the second priority (or described as "low priority" or "low priority data packet"); the first data is user uplink data sent when the terminal screen is on, and the corresponding target priority information can be the first priority (or described as "data packet" or "normal data packet"), or the third priority (or described as "high priority" or "high priority data packet").

[0070] The screen states mentioned above can be understood as the display states of the terminal, such as screen on (which can also be described as the monitor being in working state) and screen off (which can also be described as screen off, black screen, monitor being in non-working state, etc.).

[0071] In this embodiment, access control is performed based on the target priority information of the first data and / or the screen state of the terminal. That is, differentiated access control is performed for different target priorities and / or different terminal screen states. For example, different access controls are performed for high-priority first data and low-priority first data, and different access controls are performed when the terminal is in a screen-on or screen-off state. Differentiated access control can be achieved, for example, by different access control priorities or different access control configuration parameters. For instance, different first information (different priority information, and / or different screen states) can correspond to different AC values, thereby performing different access controls.

[0072] Understandably, by defining different AC values, the priority of screen-on data can be increased, or the priority of screen-off data can be decreased, thereby implementing differentiated access control. For example, lower-priority data (such as screen-off data) can have a higher probability of being blocked from access, or a lower access priority. Conversely, higher-priority data (such as screen-on data) can have a higher probability of being accessed, or a higher access priority.

[0073] In this embodiment of the application, by implementing differentiated access control under different circumstances, data congestion is reduced and the success rate of data transmission is improved.

[0074] Optionally, the target priority information of the first data is determined according to at least one of the following:

[0075] The type of terminal;

[0076] The screen status of the terminal;

[0077] Application information.

[0078] In this embodiment, the terminal can determine the target priority information of the first data based on its own type (e.g., IoT device, wearable device, etc.), that is, the type of device transmitting the first data.

[0079] In this embodiment of the application, the target priority information of the first data can also be determined based on the screen state of the terminal. The screen state of the terminal can refer to the screen state when the terminal acquires the first data, the screen state when the terminal determines that the first data needs to be transmitted, the screen state when the terminal performs an access attempt, or the screen state when the terminal performs access control, etc. Specifically, it can be understood as the screen state of the terminal related to the first data.

[0080] It is understandable that the terminal can directly execute access control based on the screen status, or it can determine the aforementioned target priority information based on the screen status before executing access control.

[0081] For example, RRC connection attempts for data services can be categorized into two types: foreground (UE screen on) and background (UE screen off), depending on the UE's activity and idle switching mode. During peak hours (e.g., 18:00-20:00), a large number of UEs may simultaneously request to establish RRC connections. Some of these UEs may be in a screen-on state (e.g., a user has opened an application requesting a service), while others may be in a screen-off state (e.g., some applications may need to send heartbeat packets). However, a large number of UEs simultaneously requesting data transmission can reduce the success rate of random access data transmission. In this embodiment, considering that the RRC connection requests from UEs in a screen-on state originate from users (e.g., a user has opened an application requesting a service), the priority of RRC connection requests from UEs in a screen-on state can be set to be higher than that from UEs in a screen-off state.

[0082] In this embodiment, the target priority information of the first data can also be determined based on application information. The aforementioned application can refer to the application associated with the first data, such as the application that generated the first data or the application that sourced the first data. The application information can be the application's identifier, application category, application type, and / or application status. For example, if the first data is an uplink data packet from a social application A, then the application information could be the identifier and / or category of social application A.

[0083] Optionally, there is a mapping relationship between the terminal type, the terminal's screen state and / or application information, and the target priority information. For example, vehicle-to-everything (V2X) terminals correspond to higher priority, wearable devices to lower priority, terminals with their screens on to higher priority, terminals with their screens off to lower priority, payment applications to higher priority, and smart home applications to lower priority. The above priority mapping relationship is only an example and is not intended to limit the specific scope of the embodiments of this application.

[0084] Optionally, the method further includes: the terminal acquiring the target priority information.

[0085] In this embodiment, the terminal can obtain the aforementioned target priority information through different channels. This acquisition can be understood as obtaining it from configuration, receiving it, receiving it after a request, obtaining it through self-learning, inferring it from unreceived information, or obtaining it after processing received information. The specific method can be determined according to actual needs, and this embodiment does not limit this. For example, the terminal can obtain the aforementioned target priority information through its own operating system (OS) and receive the target priority information configured by the network-side device.

[0086] In some implementations, the UE can obtain data priority information through the OS. Taking screen on and off as examples, the UE can obtain screen on and off information through the OS, and thus determine that the data packet priority is low priority (data packet) when the screen is off, and high priority (data packet) or (normal) data packet when the screen is on. Taking application A and application B as examples, the UE can obtain information about the APP that triggered the data transmission through the OS, and thus determine that the data packet priority of application A is low priority (data packet), and the data packet priority of application B is high priority (data packet) or (normal) data packet.

[0087] Optionally, the terminal performs access control based on the first information, including:

[0088] The terminal determines the target access category (AC) based on the first information;

[0089] The terminal performs access control based on the target AC.

[0090] In this embodiment of the application, access control can be performed by determining a target AC. In this embodiment of the application, the target AC refers to the AC value corresponding to the above-mentioned access control process. The target AC can be an AC value in related technologies, or at least one of the AC values ​​newly added in this embodiment of the application. Specifically, it can include at least one of a first AC, a second AC, and a third AC.

[0091] In this embodiment, the target AC can be determined through the target priority information of the first data and / or the screen state of the terminal. For example, different target priorities may correspond to different target ACs, and / or different terminal screen states may correspond to different target ACs.

[0092] In this embodiment of the application, the target AC may include one or more AC values.

[0093] Optionally, the target AC includes at least one of a first AC, a second AC, and a third AC;

[0094] The first AC indication includes at least one of the following: terminal response to downlink signaling from the network side; latency tolerance; emergency service; signaling initiated by the terminal; multimedia voice call initiated by the terminal; multimedia video call initiated by the terminal; short message service (SMS) initiated by the terminal; short message service based on IP (SMSoIP) initiated by the terminal; data initiated by the terminal; signaling related to IP multimedia subsystem (IMS) registration initiated by the terminal; and exception data initiated by the terminal.

[0095] The second AC indication includes at least one of the following: screen off; screen off data; screen off signaling; low priority; low priority data; low priority signaling; low priority data initiated by the terminal; low priority signaling initiated by the terminal.

[0096] The third AC indication includes at least one of the following: screen on; screen on data; screen on signaling; high priority; high priority data; high priority signaling; high priority data initiated by the terminal; high priority signaling initiated by the terminal.

[0097] In this embodiment, the target AC value determined by the terminal can be an existing AC value or a new AC value. The aforementioned first AC can be understood as an AC value already existing in related technologies, used to indicate at least one of the following:

[0098] Terminal responses to downlink signaling from the network side; delay tolerance; emergency services; terminal-initiated signaling; terminal-initiated multimedia voice calls; terminal-initiated multimedia video calls; terminal-initiated Short Message Service (SMS); terminal-initiated SMS over IP (SMSoIP); terminal-initiated data; terminal-initiated registration-related signaling for the IP Multimedia Subsystem (IMS); and terminal-initiated exception data.

[0099] This application provides new AC values—a second AC and / or a third AC—to indicate screen status and priority-related information. The value of the second AC and / or the third AC indicates the corresponding priority, which can be understood as the priority information of data (e.g., data packets) being included in the AC. Correspondingly, it is possible to determine that the data corresponds to a first AC when the data does not include / does not carry / does not have / does not have priority information, or it is possible to determine the data priority as a first priority when the data does not include / does not carry / does not have / does not have priority information. The first priority serves as a baseline priority, with lower priorities (e.g., the second priority) and higher priorities (e.g., the third priority) designated as high priorities.

[0100] It is understandable that there may be a corresponding mapping relationship between the target AC and the target priority information, and a corresponding mapping relationship between the target AC and the screen state.

[0101] This application embodiment can be understood as indicating low-priority data packets or high-priority data packets by introducing a new AC value, including:

[0102] By introducing a new AC value (second AC) to indicate low-priority data, the new AC value is used when the UE determines that the data packet priority information is low-priority data packet in the case of screen off.

[0103] By introducing a new AC value (third AC) to indicate high-priority data, when the screen is on, the new AC value is used when the UE determines that the data packet priority information is a high-priority data packet.

[0104] For example, Table 1 shows one implementation of the second AC (AC value 11), and Table 2 shows one implementation of the third AC (AC value 12). Specifically, the following mapping table can map access attempt types to access categories (ACs), with each mapping corresponding to a rule number. Among them, MO_data corresponds to data initiated by the terminal, MO_S-Off_data corresponds to data initiated when the terminal's screen is off (Screen-Off Data), and MO_S-On_data corresponds to data initiated when the terminal's screen is on (Screen-On Data).

[0105] Table 1 AC Mapping Table

[0106] Table 2 AC Mapping Table

[0107] It is worth noting that, optionally, in some implementations, if a new AC value is defined (e.g., AC=11 or AC=12), then AC=7(MO_data) will no longer contain the meaning of the new AC value (e.g., AC=11 or AC=12). That is, a piece of data cannot simultaneously satisfy both AC=7 and the new AC value (e.g., AC=11 or AC=12). It is understood that AC=7(MO_data) indicates that the terminal needs to send the user's uplink data packet. Therefore, when a new AC value (e.g., AC=11 or AC=12) is defined, the old AC value AC=7(MO_data) must exclude the meaning of the new AC value to avoid ambiguity caused by a piece of data satisfying two AC values. It should be noted that excluding the meaning of the new AC value from the old AC value does not mean that the NAS layer cannot provide two or more cause values ​​to the AS layer. For example, while providing data, the terminal's OS can also provide information to indicate screen activation. The terminal's NAS layer needs to determine a new AC value based on the information indicating screen activation. However, since the NAS does not know whether the access network supports access control based on priority information, the terminal's NAS layer can select an AC value from a related technology according to the original logic (i.e., the access control method when priority information is not introduced) and provide both AC values ​​to the AS at the same time. The AS layer then determines which AC value to use for access control.

[0108] It's understandable that "screen-off data" refers to data transmission initiated by the UE when the screen is off, and similarly, "screen-off signaling" refers to signaling transmission initiated by the UE when the screen is off. Conversely, "screen-on data" refers to data transmission initiated by the UE when the screen is on, and "screen-on signaling" refers to signaling transmission initiated by the UE when the screen is on.

[0109] Optionally, when the first information includes target priority information of the first data, the target priority information is a first priority if the first condition is met, and / or the target priority information is a second priority if the second condition is met;

[0110] The first condition includes at least one of the following: the terminal is on; the first data is not low-priority data; the first data does not have priority information; the first data is high-priority data; the terminal is on when it initiates the access attempt; the terminal obtains information indicating that the screen is on; the terminal obtains information indicating high-priority data.

[0111] The second condition includes at least one of the following: the terminal is in a screen-off state; the first data is low-priority data; the first data is not a high-priority data packet; the terminal is in a screen-off state when initiating the access attempt; the terminal obtains information indicating screen-off; the terminal obtains information indicating low-priority data.

[0112] In this embodiment, different priorities for the first data can be determined based on different conditions. Specifically, the first priority can be set to the case of screen being on, lacking priority information, high priority, and / or non-low priority, while the second priority can be set to the case of screen being off, having priority information, and / or low priority.

[0113] In another alternative embodiment, the screen off, lack of priority information, low priority and / or non-high priority cases can be set as the first priority, and the screen on, priority information and / or high priority cases can be set as the third priority.

[0114] Optionally, when the first information includes target priority information of the first data, the target priority information is a first priority if the third condition is met, and / or the target priority information is a third priority if the fourth condition is met;

[0115] The third condition includes at least one of the following: the terminal is in a screen-off state; the first data is low-priority data; the first data is not a high-priority data packet; the first data does not have priority information; the terminal is in a screen-off state when initiating an access attempt; the terminal obtains information indicating screen-off; the terminal obtains information indicating low-priority data.

[0116] The fourth condition includes at least one of the following: the terminal is on; the first data is not low-priority data; the first data is high-priority data; the terminal is on when it initiates an access attempt; the terminal obtains information indicating that the screen is on; the terminal obtains information indicating that the high-priority data is on.

[0117] In this embodiment, it can be understood that a first priority is used as the base priority, and an additional second priority or a third priority with a lower priority or a higher priority is set (the third priority is higher than the second priority). As described in the previous embodiment, for a UE (traditional UE) that cannot recognize priority information, if the transmission method of the relevant technology is followed, the data packet will be determined as an ordinary data packet and the first priority will be adopted. That is, the priority of the first data that does not have priority information will be determined as the first priority, that is, it will be determined as a data packet.

[0118] In this embodiment of the application, the priority of the data is determined by setting the above conditions, that is, the first information is determined, and access control is performed.

[0119] In another alternative embodiment, the AC value corresponding to the priority can be further determined by judging the data priority through conditions.

[0120] Optionally, the terminal determines the target access category (AC) based on the first information, including at least one of the following:

[0121] When the target priority information is the first priority, the terminal determines that the target AC includes the first AC;

[0122] When the target priority information is the second priority, the terminal determines that the target AC includes the second AC.

[0123] The meanings of the first AC and the second AC mentioned above can be found in the description of the previous embodiments, and will not be repeated here.

[0124] Optionally, the terminal determines the target access category (AC) based on the first information, including at least one of the following:

[0125] If the target priority information is the first priority, it is determined that the target AC includes the first AC;

[0126] If the target priority information is the third priority, it is determined that the target AC includes the third AC.

[0127] The meanings of the first AC and the third AC mentioned above can be found in the description of the previous embodiments, and will not be repeated here.

[0128] In another alternative embodiment, the target AC can be determined directly by judging the conditions, without needing to judge priority information based on conditions.

[0129] Optionally, the terminal determines the target access category (AC) based on the first information, including at least one of the following:

[0130] Under the condition of the fifth condition, the target AC is determined to include the first AC;

[0131] Under the sixth condition, the target AC is determined to include the second AC;

[0132] The fifth condition includes at least one of the following: the terminal is on; the first data is not low-priority data; the first data does not have priority information; the first data is high-priority data; the terminal is on when it initiates the access attempt; the terminal obtains information indicating that the screen is on; the terminal obtains information indicating high-priority data.

[0133] The sixth condition includes at least one of the following: the terminal is in a screen-off state; the first data is low-priority data; the first data is not a high-priority data packet; the terminal is in a screen-off state when it initiates an access attempt; the terminal obtains information indicating screen-off; the terminal obtains information indicating low-priority data.

[0134] The meanings of the first AC and the second AC mentioned above can be found in the description of the previous embodiments, and will not be repeated here.

[0135] In this embodiment of the application, the fifth and sixth conditions mentioned above correspond to the first information. The terminal determines the target access category AC based on the first information, which can be understood as determining the target AC value based on the fifth and / or the sixth conditions.

[0136] In some embodiments, the priority information of data packets can be defined as "data packets", "high-priority data packets" and "low-priority data packets". The "data packet" serves as the benchmark for priority information, with packets having a higher priority being called "high-priority data packets" and packets having a lower priority being called "low-priority data packets".

[0137] In this embodiment of the application, optionally, the UE provides an AC, including: the UE provides a first AC when a fifth condition is met, wherein the fifth condition includes at least one of the following: the UE determines that the screen is on; the UE determines that the data packet priority information is not a low-priority data packet; the UE determines that the data packet priority information is a data packet or a high-priority data packet; the UE determines that the screen is on when initiating an access attempt.

[0138] Optionally, the UE provides an AC, including: upon satisfying a sixth condition, the UE provides a second AC, the second AC indicating at least one of the following: screen off; screen off data; screen off signaling; low priority; low priority data; low priority signaling; low priority data initiated by the terminal; low priority signaling initiated by the terminal. The sixth condition includes at least one of the following: the UE determines to turn off the screen; the UE determines that the data packet priority information is a low-priority data packet; the UE determines that the data packet priority information is not a data packet; the UE determines that the data packet priority information is not a high-priority data packet; the UE determines to turn off the screen when initiating an access attempt.

[0139] In this embodiment, when the UE is transmitting data normally, the existing AC value (first AC) is used. Normal data transmission by the UE can be understood as the UE determining that the data packet priority information is a data packet. For example, when the screen is on, the UE determines that it is transmitting data normally or that the data packet priority information is a data packet. When the UE determines that the data packet priority information is a low-priority data packet, a new AC value (second AC) is used. For example, when the screen is off, the UE determines that the data packet priority information is a low-priority data packet. It is understood that, since related technologies do not distinguish between on-screen and off-screen states, traditional UEs (referring to UEs that do not support priority information) will only use the existing AC value for access control. Enhanced UEs (referring to UEs that support priority information) will determine whether to use the existing AC value (e.g., when the screen is on) or the new AC value (e.g., when the screen is off) based on the data packet priority information. The advantage of this is that it reduces the use of AC values ​​(because the number of AC values ​​is limited) and also minimizes the impact on the UE.

[0140] Terminal support for priority information can be understood as the terminal being able to determine the priority of data, or being able to provide at least one of the first AC, second AC, and third AC. Terminal support for priority information can be understood as the terminal being unable to determine the priority of data, or being unable to provide the second AC or third AC (or being able to provide only the first AC).

[0141] In this embodiment, "high priority" and "low priority" refer to the priorities based on data packets without priority information. Taking screen-on data and screen-off data as examples, without priority information, the UE's screen-on and screen-off data / signaling use existing AC values. After introducing priority information, if screen-on data is considered to have a higher priority than screen-off data, it can be understood that screen-on data can be considered high priority and screen-off data as its original priority; alternatively, screen-on data can be considered original priority and screen-off data as low priority; or screen-on data can be considered high priority and screen-off data as low priority.

[0142] Optionally, the terminal determines the target access category (AC) based on the first information, including at least one of the following:

[0143] Under the seventh condition, the target AC is determined to include the first AC;

[0144] Under the condition of the eighth condition, the target AC is determined to include the third AC;

[0145] The seventh condition includes at least one of the following: the terminal is in a screen-off state; the first data is low-priority data; the first data is not a high-priority data packet; the first data does not have priority information; the terminal is in a screen-off state when it initiates an access attempt; the terminal obtains information indicating screen-off; the terminal obtains information indicating low-priority data.

[0146] The eighth condition includes at least one of the following: the terminal is on; the first data is not low-priority data; the first data is high-priority data; the terminal is on when it initiates the access attempt; the terminal obtains information indicating that the screen is on; the terminal obtains information indicating that the high-priority data is on.

[0147] The meanings of the first AC and the third AC mentioned above can be found in the description of the previous embodiments, and will not be repeated here.

[0148] In this embodiment of the application, the seventh and eighth conditions correspond to the first information, and the terminal determines the target access category AC based on the first information. This can be understood as determining the target AC value based on the seventh and / or eighth conditions.

[0149] In this embodiment of the application, optionally, the UE provides AC, including: the UE provides a first AC when a seventh condition is met, wherein the seventh condition includes at least one of the following: the UE determines that the screen is off; the UE determines that the data packet priority information is a low-priority data packet; the UE determines that the data packet priority information is a data packet or a low-priority data packet; the UE determines that the screen is off when initiating an access attempt.

[0150] Optionally, the UE provides an AC, including: when an eighth condition is met, the UE provides a third AC, the third AC indicating at least one of the following: screen on; screen on data; screen on signaling; high priority; high priority data; high priority signaling; high priority data initiated by the terminal; high priority signaling initiated by the terminal. The eighth condition includes at least one of the following: the UE determines that the screen is on; the UE determines that the data packet priority information is not a low-priority data packet; the UE determines that the data packet priority information is a data packet or a high-priority data packet; the UE determines that the screen is on when initiating an access attempt.

[0151] In some implementations, packet priority information may include both data packets and high-priority data packets. When the UE transmits data while the screen is off, an existing AC value (first AC) is used. Here, UE transmitting data while the screen is off can be understood as the UE determining the packet priority information as a data packet. For example, in the off-screen state, the UE determines to transmit data or determines the packet priority information as a data packet. When the UE determines the packet priority information as a high-priority data packet, a new AC value (third AC) is used. It is understood that since related technologies do not distinguish between on-screen and off-screen states, conventional UEs (referring to UEs that do not support packet priority information) will only use existing AC values ​​for access control. Therefore, enhanced UEs (referring to UEs that support packet priority information) will determine whether to use an existing AC value (e.g., when the screen is off) or a new AC value (e.g., when the screen is on) based on the packet priority information. The advantage of this is that it reduces the use of AC values ​​(because the number of AC values ​​is limited) and also minimizes the impact on the UE.

[0152] In this embodiment of the application, optionally, the target AC can be determined by the NAS layer. The NAS layer of the terminal can provide the AC value to the AS layer of the UE to perform access control. That is, the AS layer can determine the target AC through the target AC provided by the NAS layer.

[0153] Optionally, the terminal determines the target access category (AC) based on the first information, including:

[0154] The non-access layer of the terminal performs at least one of determining the target AC and providing the target AC to the access layer of the terminal based on the first information;

[0155] Wherein, the target AC satisfies any one of the following:

[0156] The target AC includes the first AC;

[0157] The target AC includes the second AC;

[0158] The target AC includes a third AC;

[0159] The target AC includes a first AC and a second AC;

[0160] The target AC includes the first AC and the third AC.

[0161] In this embodiment of the application, as shown in FIG3, the terminal (e.g., UE) and the access network device (e.g., RAN) are peer entities, and the internal communication between the terminal is a protocol layer interaction between the higher layer (UE NAS or UE non-access layer) and the lower layer (UE AS or UE access layer).

[0162] In this embodiment of the application, the non-access layer (i.e., the NAS layer) can be used to determine the target AC, or to provide the target AC to the access layer (i.e., the AS layer). Alternatively, the non-access layer (i.e., the NAS layer) can be used to determine the target AC and provide the target AC determined by the NAS layer to the AS layer. The aforementioned target AC can be one or more, and the target AC provided by the NAS layer to the AS layer can also be one or more.

[0163] Optionally, the UE providing an AC includes: the UE providing only one AC. For example, in some implementations, when the UE determines whether the network side supports or does not support packet priority information, the UE's NAS layer decides to instruct the second AC or the first AC to the UE's AS layer for performing access control. For example, when the UE determines that the network side supports packet priority information, the UE can provide the second AC when the screen is off and provide the first AC when the screen is on. As another example, when the UE determines that the network side does not support packet priority information, the UE provides only the first AC.

[0164] Optionally, the UE provides an AC, including providing two ACs. For example, it may provide a first AC and a second AC, with the first AC indicating a multimedia voice call initiated by the terminal and the second AC indicating screen off. For example, in some embodiments, the UE's NAS layer cannot determine whether the network side supports or does not support packet priority information. In this case, the UE's NAS layer provides the first AC and the second AC to the UE's AS layer, and the UE's AS layer determines whether to use the first AC or the second AC to perform access control. For example, the UE's AS layer can determine whether to use the first AC or the second AC to perform access control based on an indication received from a base station broadcast message (the indication can refer to the second information in the embodiments below). It is understood that since the UE's NAS layer cannot determine whether the network side supports or does not support packet priority information, on the one hand, if only the second AC is provided to the UE's AS layer, but the network side (such as the access network equipment) does not broadcast the second AC, the UE cannot perform access control; on the other hand, if only the first AC is provided to the UE's AS layer, the first AC may not reflect the packet priority information.

[0165] In this embodiment of the application, the access network device can directly send indication information indicating whether the access network device supports or does not support data priority information, or it can indicate AC value and / or AC value association information, implicitly indicating whether the access network device supports or does not support data priority information through AC value and / or AC value association information.

[0166] Optionally, the method further includes: the terminal receiving second information from the access network device, the second information satisfying at least one of the following:

[0167] The second information is used to indicate whether the access network device supports or does not support access control based on priority information;

[0168] The second information is used to instruct the access network device to enable or disable access control based on priority information.

[0169] The method further includes: the UE obtaining information used to indicate whether the network-side device supports or does not support priority information.

[0170] In one optional implementation, the terminal obtains information on whether the network side supports or does not support access control based on priority information by receiving the aforementioned second information. In some implementations, the UE can obtain information on whether the access network device supports or does not support access control based on priority information through broadcast information. In some implementations, the access network device can distinguish whether it supports or does not support access control based on priority information through a 1-bit explicit indication. In some implementations, the access network device can implicitly indicate whether it supports or does not support access control based on priority information through the AC value broadcast by the SIB. For example, if the access network device broadcasts an AC value that supports packet priority information (e.g., AC value = 15), it indicates that the access network device supports access control based on priority information. As another example, if the access network device does not broadcast an AC value that supports priority information (e.g., AC value = 7), it indicates that the access network device does not support access control based on priority information. It is understood that the UE's AS layer can learn whether the access network device supports or does not support access control based on priority information from the broadcast information when camped on the cell, and the UE performs access control when packets are transmitted. Therefore, exchanging whether packet priority information is supported or not allows the UE's NAS layer to determine whether to provide a new AC value (second AC or third AC) to the UE's AS layer.

[0171] In one alternative implementation, the second information may also indicate whether the access network device allows or disallows access control based on priority information. For example, the terminal can only perform access control based on priority information if the terminal supports it and the access network device allows it. It is understood that the access network device supporting access control based on priority information is not equivalent to the access network device allowing access control based on priority information.

[0172] The access network device enables or disables access control based on priority information by sending the second information, which can be understood as the access network device enabling or disabling the access control function based on priority information.

[0173] The terminal obtains information from the network side regarding whether priority-based access control is enabled or disabled by receiving the aforementioned second information. In some embodiments, the UE can obtain this information through broadcast information. In some embodiments, the access network device can explicitly indicate whether priority-based access control is enabled or disabled using a 1-bit indicator. In some embodiments, the access network device can implicitly indicate whether priority-based access control is enabled or disabled using the AC value broadcast by the SIB. For example, if the access network device broadcasts an AC value that enables packet priority information (e.g., AC value = 15), it indicates that the access network device enables priority-based access control. Conversely, if the access network device does not broadcast an AC value that enables priority information (e.g., AC value = 7), it indicates that the access network device does not enable priority-based access control. It is understandable that the UE's AS layer can learn from broadcast information whether the access network device enables or disables access control based on priority information when camped on a cell. Since the UE performs access control during data packet transmission, interacting with enabling or disabling data packet priority information allows the UE's NAS layer to determine whether to provide a new AC value (second AC or third AC) to the UE's AS layer. In this application embodiment, the access network device supporting priority information can be understood as the access network device being able to provide or broadcast the second AC and its associated information, and / or being able to identify or broadcast the third AC and its associated information. The access network device not supporting priority information can be understood as the access network device only being able to provide or broadcast the first AC and its associated information, and not being able to provide or broadcast the second AC and its associated information, nor being able to identify or broadcast the third AC and its associated information.

[0174] Optionally, if the UE's AS layer obtains information on whether the access network device supports or does not support data packet priority information through broadcast information, the UE's AS layer may provide the information on whether the access network device supports or does not support data packet priority information to the NAS layer.

[0175] In one alternative implementation, the terminal receives second information from a network-side device (which can also be described as a network function, such as an access and mobility management function), the second information indicating whether the access network device supports or does not support priority information. For example, the UE can obtain information about whether the access network device supports or does not support packet priority information through a NAS message. For example, the network-side device can indicate to the UE whether the access network device supports or does not support packet priority information in the UE's registration acceptance message.

[0176] Optionally, the terminal performs access control based on the first information, including:

[0177] The terminal performs access control based on the second information and the first information.

[0178] In this embodiment, the access network device indicates second information to the terminal, namely, information on whether the network side supports or does not support data packet priority information, and then performs access control based on the obtained first and second information. For example, the terminal may determine a target AC based on the first information, and perform access control through the target AC and the information broadcast by the access network device for performing access control.

[0179] Optionally, the terminal performs access control based on the second information and the first information, including:

[0180] The non-access layer of the terminal obtains the second information from the access layer of the terminal;

[0181] The terminal's non-access layer determines the target AC based on the second information and the first information;

[0182] The non-access layer of the terminal provides the target AC to the access layer of the terminal, and the target AC is used to perform access control.

[0183] In this embodiment of the application, the non-access layer of the terminal may obtain the second information mentioned above through the access layer to determine the target AC, so that the access layer can perform access control.

[0184] Optionally, the terminal performs access control based on the second information and the first information, including:

[0185] The terminal's access layer obtains the target AC from the terminal's non-access layer;

[0186] The terminal's access layer determines the AC used to perform access control based on the second information and the first information, wherein the AC used to perform access control is at least one of the target ACs;

[0187] The terminal's access layer performs access control according to the AC used for performing access control.

[0188] In this embodiment of the application, the terminal's access layer may obtain the target AC information provided by the non-access layer and the second information provided by the access network device to determine the AC for performing access control, so as to perform access control.

[0189] Optionally, the method further includes: the terminal sending third information to the access network device, the third information indicating at least one of the following: the terminal supports or does not support data priority information; the terminal enables or disables data priority information; the terminal supports or does not support access control based on data priority information; the terminal enables or disables access control based on data priority information.

[0190] In this embodiment, the terminal can report the third information to the network-side device, enabling the network-side device to implement access control per UE. Optionally, the terminal can indicate to the network side whether it supports or does not support packet priority information via Mobility Management (MM) capabilities in the registration request message.

[0191] The embodiments of this application can be understood as the interaction of capabilities between access network devices and terminals.

[0192] Optionally, if the terminal (UE) does not support priority information, or if the UE determines that the network does not support priority information, an existing AC value can be used to perform access control (i.e., the UE's NAS layer can provide an existing AC value to the AS layer), namely the first AC value. For example, in a UE that does not support packet priority information, the UE uses an existing AC value (i.e., the UE's NAS layer can provide an existing AC value to the AS layer) to perform access control. In this way, even if the network side that supports packet priority information broadcasts a new AC value, the UE can still correctly perform access control. As another example, if the UE determines that the network side does not support packet priority information, the UE uses an existing AC value (i.e., the UE's NAS layer can provide an existing AC value to the AS layer) to perform access control. In this way, since the network side that does not support packet priority information can only broadcast based on existing AC values, the UE can correctly utilize existing AC values ​​to perform access control.

[0193] In this embodiment, the terminal can determine the target AC based on the first information and simultaneously determine the usable AC by referring to the second information (priority information on whether the access network device supports or does not support it).

[0194] For example, Figure 4 illustrates an access control flow. It is understood that the steps shown by the dashed lines (arrows and boxes) in Figure 4 are optional steps in this flow.

[0195] Optionally, the method further includes: the terminal determining a Radio Resource Control (RRC) cause value based on the first information, wherein the RRC cause value satisfies any one of the following:

[0196] The RRC cause value indicates at least one of the following: screen off; screen off data; screen off signaling; low priority; low priority data; low priority signaling; low priority data initiated by the terminal; low priority signaling initiated by the terminal.

[0197] The RRC cause value indicates at least one of the following: screen on; screen on data; screen on signaling; high priority; high priority data; high priority signaling; high priority data initiated by the terminal; high priority signaling initiated by the terminal.

[0198] In this embodiment, the terminal can further determine the RRC cause value based on the first information. The optional RRC cause values ​​include first-class cause values ​​(screen off; screen off data; screen off signaling; low priority; low priority data; low priority signaling; terminal-initiated low priority data; terminal-initiated low priority signaling), and / or second-class cause values ​​(screen off; screen off data; screen off signaling; low priority; low priority data; low priority signaling; terminal-initiated low priority data; terminal-initiated low priority signaling). The terminal can determine the RRC cause value as at least one of the first-class cause values, or determine the RRC cause value as at least one of the second-class cause values, based on the first information.

[0199] In this embodiment, the terminal can further determine the RRC cause value based on the first information. This can be done by determining the RRC cause value based on target priority information and / or the terminal's screen state, or by determining the target AC based on the first information and then determining the RRC cause value based on the target AC. For example, the UE determines the RRC establishment cause value based on at least one of the first AC and the second AC, or the UE determines the RRC establishment cause value based on at least one of the first AC and the third AC. Since a new AC value (the second AC or the third AC) is used, the corresponding RRC cause value also includes a new reason for RRC establishment; that is, the RRC cause value determined based on the second AC or the third AC is a new RRC establishment cause.

[0200] Optionally, the NAS layer can determine the aforementioned RRC cause value and provide it to the AS layer.

[0201] In the embodiments of this application, the specific process of performing access control based on the target AC can be referred to the description in related technologies, and will not be repeated here. Unlike related technologies, in some embodiments provided in this application, when the terminal performs access control, it may, under certain circumstances, determine to skip the execution of access control.

[0202] Optionally, the terminal performs access control based on the first information, including:

[0203] If the ninth condition is met, the terminal determines to skip the execution of the access control.

[0204] When the first information includes target priority information of the first data, the terminal performs access control based on the first information, including:

[0205] If the target priority information is the fourth priority, the terminal determines to skip the execution of the access control.

[0206] Among them, if the ninth condition is met, the target priority information is the fourth priority;

[0207] The ninth condition includes at least one of the following:

[0208] The terminal is on screen; the first data is not low-priority data; the first data does not have priority information; the first data is high-priority data; the terminal is on screen when initiating an access attempt; the terminal obtains information indicating screen on; the terminal obtains information indicating high-priority data.

[0209] In this embodiment of the application, it can be determined not to execute access control based on the ninth condition, or the target priority can be determined to be the fourth priority based on the ninth condition, thereby determining not to execute access control.

[0210] Optionally, if the target AC value is a first preset value, the access control is skipped. The target AC value can be the first preset value if the ninth condition is met, or it can be the first preset value if the target priority information is the fourth priority.

[0211] Unlike related technologies, the embodiments of this application can determine to skip access control based on a preset ninth condition or a preset fourth priority. For example, the UE determines to skip access control based on data packet priority information (e.g., the data packet priority information is high priority). It can be understood that by skipping the execution of access control, the terminal can ensure that the RRC connection establishment request is not blocked (barred) even if the data packet priority information is high priority, thus protecting the user experience.

[0212] In this embodiment, the terminal performs access control based on first information; wherein the first information includes at least one of the following: target priority information of the first data; and the screen state of the terminal. That is, differentiated access control is performed based on different data priorities and / or different states of the terminal display screen, reducing data congestion and improving the success rate of data transmission.

[0213] Referring to Figure 5, which is a flowchart of an access control method provided in an embodiment of this application, for use in an access network device, the method includes the following steps:

[0214] Step 501: The access network device sends second information to the terminal, wherein the second information satisfies at least one of the following:

[0215] The second information is used to indicate whether the access network device supports or does not support access control based on priority information;

[0216] The second information is used to instruct the access network device to enable or disable access control based on priority information.

[0217] In this embodiment, the access network device can directly send indication information indicating whether it supports or does not support data priority information, or it can indicate the AC value and / or the associated information of the AC value, implicitly indicating whether the access network device supports or does not support data priority information through the AC value and / or the associated information of the AC value. For example, the second information is a broadcast AC; the second information is associated with the AC.

[0218] For example, the RAN can broadcast information indicating whether the access network device supports or does not support packet priority information. In some implementations, the access network device can explicitly indicate whether it supports or does not support packet priority information using a 1-bit indication. In other implementations, the access network device can implicitly indicate whether it supports or does not support packet priority information using the AC value broadcast by the SIB. For example, if the access network device broadcasts an AC value indicating support for packet priority information, it means that the access network device supports packet priority information. Conversely, if the access network device does not broadcast an AC value indicating support for packet priority information, it means that the access network device does not support packet priority information.

The specific implementation method can be found in the relevant description of the embodiment shown in Figure 2.
