In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

Unified Access Control (UAC)

For load control on the network side, UAC mechanism is introduced in NR. In the UAC mechanism, the access category (Access Category) and the access identity (Access identity) are defined. Its meaning is shown in Table 1 and Table 2 below.

Table 1

Table 2

●UAC parameter configuration

The access network element (such as the base station) broadcasts the access control information related to the access category and the access identifier, and the access layer (Access Stratum, AS) of the UE is based on the access control information and the AS layer or non-access layer (Non Access Stratum, NAS) provides access category and access identifier to perform access control operations (ie ACB checking).

The access control information broadcast by the access network elements includes UAC parameters. UAC parameters are based on the access category as the granularity (per access category) and/or the public land mobile network (Public Land Mobile Network, PLMN) as the granularity (per PLMN). ) For configuration. The UAC parameter is specifically the UAC-BarringInfoSet. The network side can configure up to 8 UAC-BarringInfoSet, each access category is associated with a UAC-BarringInfoSet, a total of 64 access categories (access category 0 does not need to be configured) . Each PLMN can also be associated with one UAC-BarringPerCatList. Further, if the per PLMN information is not configured, the above configuration is applicable to all PLMNs.

For access category 1, configure an auxiliary information to assist in determining whether an access control operation (ie ACB checking) is used for access category 1, and the auxiliary information is uac-AccessCategory1-SelectionAssistanceInfo.

●UAC mechanism: access control operation (ie ACB checking)

The access control operation is performed based on UAC parameters (ie, UAC-BarringInfoSet), and the specific content of UAC-BarringInfoSet is shown in Figure 2. Under the premise that neither T390 nor T302 is running and the access category is not access category 0, the execution of the access control operation includes the following steps:

1) If the bit corresponding to the access identifier in uac-BarringForAccessIdentity is set to 0, it means that access is allowed. If the corresponding bit is set to 1, then the following step 2) needs to be further judged;

2) Generate a random number (rand), the range of rand is 0≤rand<1, if the random number is lower than uac-BarringFactor, it means access is allowed, otherwise it means access is prohibited. If access is prohibited, a random number (rand) is generated, and the range of rand is 0≤rand<1, and T390 is activated and T390=(0.7+0.6×rand)×uac-BarringTime.

For events triggered by the NAS layer, the NAS layer determines the access identifier, access category, and access reason (or called cause value). The NAS layer provides the access identifier and access category to the AS layer, and the AS layer is responsible for performing access control operations. If access is allowed, the AS layer notifies the NAS layer, and the NAS layer provides the reason for the access to the AS layer. Based on the feedback of the access control operation of the AS layer, the NAS layer is responsible for stopping or allowing service transmission.

Events triggered by the AS layer include events triggered by paging or events triggered by RAN Notification Area Update (RNAU), where:

For events triggered by Paging: the access category is access category 0, which is not controlled by access control operations. In addition, the cause value is overwritten, the NAS layer and the AS layer interact, and the NAS layer provides the cause value.

For events triggered by RNAU: the access category is access category 8. The access identifier needs to be provided by the NAS layer to the AS layer, and the information exchange between the NAS layer and the AS layer belongs to the behavior of the UE. The reason value is determined by the AS layer as rna-Update.

EDT data transmission

EDT data transmission is introduced in LTE. During the EDT data transmission, the UE may always remain in the idle state or suspended state or inactive state to complete the uplink and/or downlink EDT data transmission .

EDT data transmission can adopt the control plane transmission scheme, as shown in Figure 3-1, including the following steps:

1. The UE sends an RRC early data request (RRCEarlyDataRequest) message to the eNB.

Here, the RRCEarlyDataRequest message may also be referred to as an EDT data transmission request message, or a small data transmission request message, or a small data packet transmission request message, or a small packet data transmission request message.

Here, the RRCEarlyDataRequest message carries the following information: S-TMSI, establishmentCause, and dedicatedInfoNAS. dedicatedInfoNAS is EDT data (or called small data, or small data packet, or small packet data).

2. The eNB sends an initial UE message (Initial UE message) to the MME, and the initial UE message carries a NAS message (NAS message).

3. Modify Bearer between MME and S-GW.

4. The MME sends uplink data (Uplink data) to the S-GW.

5. The S-GW sends downlink data (Downlink data) to the MME.

6a. Downlink NAS transmission (DL NAS TRANSPORT).

6b. Establish a connection (CONNECTION).

7. The eNB sends an RRC early data complete (RRCEarlyDataComplete) message to the UE.

Here, the RRCEarlyDataComplete message carries dedicatedInfoNAS, which is EDT data (or called small data, or small data packet, or small packet data).

8. Modify the bearer between the MME and the S-GW (Modify Bearer), and perform the S1 release procedure (S1 release procedure) between the eNB and the MME.

EDT data transmission can also adopt the user plane transmission scheme, as shown in Figure 3-2, including the following steps:

1. The UE sends an RRC Connection Resume Request (RRCConnectionResumeRequest) message and uplink data (Uplink data) to the eNB.

Here, RRCConnectionResumeRequest carries the following information: resumeID, resumeCause, shortResumeMAC-I.

2. The eNB sends a UE Context Resume Request (UE Context Resume Request) message to the MME.

3. Modify Bearer between MME and S-GW.

4. The MME sends a UE Context Resume Response (UE Context Resume Response) message to the eNB.

5. The eNB sends uplink data (Uplink data) to the S-GW.

6. The S-GW sends downlink data (Downlink data) to the eNB.

7. Modify Bearer (Modify Bearer) between MME and S-GW, and execute S1 Suspend procedure (S1 Suspend procedure) between eNB and MME.

8. The eNB sends an RRC connection release (RRCConnectionRelease) message and downlink data (Downlink data) to the UE.

Here, the RRCConnectionRelease message carries the following information: releaseCause, releaseID, and NCC.

It should be noted that Figure 3-1 and Figure 3-2 take LTE as an example for illustration. NR is the same as LTE. The difference is that for NR, eNB needs to be replaced with gNB. Mobility Management Entity (MME) ) Is replaced by an access and mobility management function entity (AMF, Access and Mobility Management Function), and a serving gateway (Serving Gateway, S-GW) is replaced by a user plane function entity (UPF, User Plane Function).

For the EDT data transmission in the above two schemes, the UE completes the EDT data transmission without entering the connected state. This type of transmission is different from the data transmission in the connected state. For EDT data transmission, it does not occupy a lot of radio resources, which is different from the radio resources occupied by RRC access for MO data transmission of MBB services. For this reason, it is necessary to clarify an access control requirement for EDT data transmission. The embodiment of the present application provides an access control method for EDT data transmission, so that access control is reasonable and effective, and data transmission is timely and effective.

Fig. 4 is a schematic flowchart 1 of the access control method provided by an embodiment of the application. As shown in Fig. 4, the access control method includes the following steps:

Step 401: The terminal receives first configuration information sent by a network device, where the first configuration information includes at least one access control parameter set.

In the embodiments of the present application, the terminal may be any device capable of communicating with the network, such as a mobile phone, a tablet computer, a notebook, a vehicle-mounted terminal, and a wearable device.

In the embodiment of the present application, the network device may be a base station, such as a 5G base station (i.e. gNB) or a 4G base station (i.e. eNB).

In the embodiment of the present application, the terminal receives first configuration information sent by a network device, where the first configuration information includes at least one access control parameter set. In an optional implementation manner, the first configuration information is carried in a system broadcast message. For example, a base station sends a system broadcast message, the system broadcast message carries first configuration information, and the terminal obtains the first configuration information from the system broadcast message. Here, the first configuration information is specifically UAC parameter configuration, and the first configuration information includes at least An access control parameter set. The access control parameter set can be UAC-BarringInfoSet. Refer to Figure 2 for the content of UAC-BarringInfoSet. UAC-BarringInfoSet includes the following parameters: uac-BarringForAccessIdentity, uac-BarringFactor, uac-BarringTime.

In the first configuration information, an access control parameter set (ie, UAC-BarringInfoSet) is configured with the granularity of the access category, and each access category is associated with an access control parameter set.

Step 402: The terminal determines a first access category corresponding to EDT data transmission, and determines a first access control parameter set corresponding to the first access category from the first configuration information, and according to the first access category An access control parameter set executes the access control operation corresponding to the EDT data transmission.

Here, EDT data transmission is also called small data transmission or small data packet transmission or small packet data transmission. The embodiment of this application defines one or more new access categories for wireless access of EDT data transmission, which will be described in detail below.

Manner 1: The wireless access of the EDT data transmission is associated with an access category.

1) The NAS layer of the terminal determines that there is EDT data transmission, and sends first indication information to the AS layer of the terminal. The first indication information is used to indicate the first access category and the first access category corresponding to the EDT data transmission. An access identifier;

2) The AS layer of the terminal determines the first access control parameter set corresponding to the first access category from the first configuration information, and according to the first access identifier and the first access Enter the control parameter set and perform the access control operation.

Specifically, define a new access category for the wireless access of EDT data transmission. This new access category coexists with the access category corresponding to the existing MO data transmission. For example, define the new access category as MO small data (MO small data) access category. The UE NAS (that is, the NAS layer of the terminal) determines that if an EDT data transmission is to be performed, the UE NAS indicates the first access category and the first access identifier corresponding to the UE AS (that is, the AS layer of the terminal) EDT data transmission. The UE AS performs an access control operation according to the first access category provided by the UE NAS, the first access identifier, and the first configuration information obtained from the system broadcast message. Specifically, the UE AS determines the first access control parameter set corresponding to the first access category from the first configuration information according to the access category provided by the UE NAS, and according to the first access identifier and The first access control parameter set performs an access control operation. The access control operation can refer to the relevant description of the aforementioned UAC mechanism, and will not be repeated.

It should be noted that the access control parameter set (ie UAC-BarringInfoSet) corresponding to the first access category and the first access identifier needs to be added to the first configuration information, where the first access category and the first access The identification corresponds to the EDT data transmission.

Manner 2: The wireless access of the EDT data transmission is associated with multiple access categories, and different access categories correspond to different EDT access reasons.

1) The NAS layer of the terminal determines the EDT data transmission and the EDT access reason corresponding to the EDT data transmission, and sends first indication information to the AS layer of the terminal, where the first indication information is used to indicate the EDT Data transmission and the first access category and the first access identifier corresponding to the EDT access reason;

Specifically, at least two new access categories are defined for wireless access of EDT data transmission, that is, each EDT access reason corresponds to an access category, and the EDT access reason may be mo-Data or delayTolerantAccess. At least two new access categories coexist with the access categories corresponding to the existing MO data transmission. The UE NAS (that is, the NAS layer of the terminal) determines that if an EDT data transmission and the reason for EDT access are to be performed, the UE NAS indicates the first access category and the first access corresponding to the UE AS (that is, the AS layer of the terminal) EDT data transmission Into the logo. The UE AS performs an access control operation according to the first access category provided by the UE NAS, the first access identifier, and the first configuration information obtained from the system broadcast message. Specifically, the UE AS determines the first access control parameter set corresponding to the first access category from the first configuration information according to the access category provided by the UE NAS, and according to the first access identifier and The first access control parameter set performs an access control operation. The access control operation can refer to the relevant description of the aforementioned UAC mechanism, and will not be repeated.

It should be noted that the access control parameter set (ie UAC-BarringInfoSet) corresponding to the first access category and the first access identifier needs to be added to the first configuration information, where the first access category and the first access The identifier corresponds to the EDT data transmission and EDT access reason.

In the embodiments of this application, for the above two methods, if the access control parameter set corresponding to the first access category provided by the NAS layer of the terminal is not configured in the system broadcast message, the terminal does not perform an access control operation.

Further, in some optional implementation manners of the present application, the method further includes:

The terminal determines the data transmission type;

If the data transmission type belongs to EDT data transmission, the terminal determines the first access corresponding to the first access type from the first configuration information according to the first access type corresponding to the EDT data transmission. Into the control parameter set;

If the data transmission type belongs to multi-packet data transmission, the terminal determines from the first configuration information the second access class corresponding to the second access class according to the second access class corresponding to the multi-packet data transmission 2. Access control parameter set;

Wherein, the number of data packets corresponding to the multi-packet data transmission is greater than the number of data packets corresponding to the EDT data transmission.

For example: Suppose the data transmission of one package belongs to EDT data transmission, and the data transmission of multiple packages belongs to multi-packet data transmission. The terminal determines whether it needs to perform EDT data transmission or multi-packet data transmission. If it is to perform EDT data transmission, Then select the corresponding first access control parameter set from the first configuration information; if multi-packet data transmission is performed, select the corresponding second access control parameter set from the first configuration information.

In the embodiment of the present application, the terminal determines the type of the first RRC message (hereinafter referred to as the first RRC message) to be sent to the network side according to the data transmission type (that is, EDT data transmission or multi-packet data transmission). Specifically, If the data transmission type belongs to EDT data transmission, the first RRC message sent by the terminal in wireless access is an EDT data transmission request message; if the data transmission type belongs to multi-packet data transmission, the terminal is The first RRC message sent in wireless access is an RRC connection establishment request message. It should be noted that the EDT data transmission request message may also be referred to as a small data transmission request message, or a small data packet transmission request message, or a small data packet transmission request message. The EDT data transmission request message is an uplink RRC message that carries EDT data (or called small data, or small data packet, or small packet data).
