In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the technical solutions related to the embodiments of the present application.

Unified access control (Unified Access Control, UAC)

For load control at the network side, a UAC mechanism is introduced in the NR. In the UAC mechanism, an Access Category (Access Category) and an Access identity (Access identity) are defined. The meanings are shown in tables 1 and 2 below.

TABLE 1

TABLE 2

● UAC parameter configuration

An Access network element (e.g., a base station) broadcasts Access control information related to an Access category and an Access identifier, and an Access Stratum (AS) of the UE performs an Access control operation (i.e., ACB checking) according to the Access control information and the Access category and the Access identifier provided by the AS layer or the non-Access Stratum (Non Access Stratum, NAS).

The access control information broadcast by the access network element comprises UAC parameters configured with access class granularity (per access category) and/or with public land mobile network (Public Land Mobile Network, PLMN) granularity (per PLMN). The UAC parameter is specifically a UAC restriction information set (UAC-barrecinnfoset), and the network side configures at most 8 UAC-barrecinnfoset, and each access category is associated with one UAC-barrecinnfoset, for a total of 64 access categories (where access category 0 does not need to be configured). It is also possible to associate one UAC-barrengpercatlist per PLMN, further if the per PLMN information is not configured, the above configuration is applicable for all PLMNs.

For the access category1, an auxiliary information is configured to assist in judging whether to access the control operation (i.e., ACB checking) for the access category1, and the auxiliary information is uac-access category1-SelectionAssistanceInfo.

● UAC mechanism: access control operation (i.e. ACB checking)

The access control operation is performed based on a UAC parameter (i.e., UAC-barrecinfoset), which is specifically included in fig. 2. On the premise that neither T390 nor T302 is running and the access class is not access category 0, the execution of the access control operation includes the steps of:

1) If the corresponding bit (bit) of the access identifier in uac-barrengForAccess identity is set to 0, which indicates that the access is allowed, if the corresponding bit is set to 1, further decision is needed through the following step 2);

2) A random number (rand) is generated, the range of rand is 0.ltoreq.rand < 1, if the random number is lower than uac-barrenfactor, access is allowed, otherwise access is forbidden. If access is forbidden, a random number (rand) is generated, the range of rand is 0.ltoreq.rand < 1, T390 is enabled and T390= (0.7+0.6Xrand). Times. uac-BarringTime.

For NAS layer triggered events, the NAS layer decides the access identity, access class, and access cause (or cause value). The NAS layer provides access identities and access categories to the AS layer, which is responsible for performing access control operations. If access is allowed, the AS layer informs the NAS layer that the NAS layer provides the access cause to the AS layer. Based on the feedback of the access control operation of the AS layer, the NAS layer is responsible for performing a stop or allowing traffic transmission.

For AS layer triggered events, including paging (paging) triggered events, or RAN notification area update (RAN Notification Area Update, RNAU) triggered events, where,

for Paging triggered events: the access category is access category 0, which is not controlled by the access control operation. In addition, the cause value is overridden, interaction between NAS layer and AS layer, NAS layer provides the cause value.

For RNAU triggered events: the access category is access category 8, the access identifier needs to be provided for the AS layer by the NAS layer, and interaction information between the NAS layer and the AS layer belongs to UE realization behaviors. The cause value AS layer is determined AS a rn-Update.

EDT data transmission

EDT data transmission is introduced in LTE, and in the EDT data transmission process, the UE may always remain in an idle (idle) state, a suspended (suspended) state, or an inactive (inactive) state, so as to complete the EDT data transmission in uplink and/or downlink.

The EDT data transmission may employ a control plane transmission scheme, as shown in fig. 3-1, comprising the steps of:

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 packet transmission request message, or a small packet data transmission request message.

Here, the RRCEarlyDataRequest message carries the following information: S-TMSI, establishmentCause, dedicatedInfoNAS. The dediedbnfonas is EDT data (or referred to as small data, or small data packets, or small packet data).

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

3. The Bearer (modified Bearer) is modified between the MME and the S-GW.

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

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

6a, downlink NAS TRANSPORT (DLNAS TRANSPORT).

6b, establishing a CONNECTION (CONNECTION).

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

Here, the RRCEarlyDataComplete message bearer dedicatedInfoNAS, dedicatedInfoNAS is EDT data (alternatively referred to as small data, or small data packets, or small packet data).

8. The Bearer (modification Bearer) is modified between the MME and the S-GW, and an S1 release procedure is performed between the eNB and the MME (S1 release procedure).

The EDT data transmission may also employ a user plane transmission scheme, as shown in fig. 3-2, comprising the steps of:

1. the UE transmits an RRC connection resume request (RRCConnectionResumeRequest) message to the eNB, and Uplink data (Uplink data).

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

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

3. The Bearer (modified Bearer) is modified between the MME and the S-GW.

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

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

6. The S-GW transmits Downlink data to the eNB.

7. The Bearer (modification Bearer) is modified between the MME and the S-GW, and an S1 suspension procedure is performed between the eNB and the MME (S1 Suspend procedure).

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

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

Fig. 3-1 and fig. 3-2 are an illustration of LTE, and NR is the same as LTE, except that for NR, eNB needs to be replaced with gNB, mobility management function entity (MME, mobility Management Entity) is replaced with an access and mobility management function entity (AMF, access and Mobility Management Function), and Serving Gateway (S-GW) is replaced with a user plane function entity (UPF, user Plane Function).

For the EDT data transmission of the two schemes, the UE completes the EDT data transmission without entering the connected state, and such transmission is different from the data transmission entering the connected state. For EDT data transmission, it does not occupy a lot of radio resources, unlike the radio resources occupied by RRC access for MO data transmission of MBB traffic. Therefore, an access control requirement is required to be defined for the EDT data transmission, and an access control mode for the EDT data transmission is provided in the embodiment of the application, so that the access control is reasonable and effective, and the data transmission and time effectiveness are ensured.

Fig. 4 is a flowchart of an access control method provided in an embodiment of the present application, as shown in fig. 4, where the access control method includes the following steps:

step 401: the terminal receives first configuration information sent by the network equipment, wherein the first configuration information comprises at least one access control parameter set.

In this embodiment of the present application, the terminal may be any device capable of communicating with a 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, for example, a 5G base station (i.e., gNB), and a 4G base station (i.e., eNB).

In this 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 alternative embodiment, the first configuration information is carried in a system broadcast message. For example: the 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, wherein the first configuration information is specifically UAC parameter configuration, the first configuration information comprises at least one access control parameter set, the access control parameter set can be UAC-BarringInfoSet, UAC-BarringInfoset, the content of which is shown in fig. 2, and the UAC-BarringInfoset comprises the following parameters: uac-BarringForAccessIdentity, uac-BarringFactor, uac-BarringTime.

In the first configuration information, access control parameter sets (i.e., UAC-barrenninfoset) are configured with access categories as granularity, and each access category is associated with one access control parameter set.

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

EDT data transmission is also referred to herein as small data transmission or small data packet transmission or small packet data transmission. The embodiment of the present application defines one or more new access categories for wireless access of EDT data transmission, which are described in detail below.

Mode one: the wireless access of the EDT data transmission is associated with an access class.

1) The NAS layer of the terminal determines that EDT data transmission exists, and sends first indication information to the AS layer of the terminal, wherein the first indication information is used for indicating a first access category and a first access identifier corresponding to the EDT data transmission;

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

Specifically, a new access class is defined for the wireless access of EDT data transmission, and the new access class coexist with the access class corresponding to the existing MO data transmission, for example, the new access class is defined as the access class of MO small data (MO small data). The UE NAS (i.e., NAS layer of the terminal) determines that if one EDT data transmission is to be performed, the UE NAS indicates a first access class and a first access identifier corresponding to the EDT data transmission of the UE AS (i.e., AS layer of the terminal). And the UE AS executes access control operation according to the first access category, the first access identifier and the first configuration information acquired from the system broadcast message provided by the UE NAS. Specifically, the UE AS determines a 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 executes an access control operation according to the first access identifier and the first access control parameter set. The access control operation may refer to the related description of the aforementioned UAC mechanism, and will not be described in detail.

It should be noted that, in the first configuration information, an access control parameter set (i.e., UAC-barrenninfoset) corresponding to a first access class and a first access identifier needs to be added, where the first access class and the first access identifier correspond to EDT data transmission.

Mode two: and the wireless access of the EDT data transmission is associated with a plurality of access categories, and different access categories correspond to different EDT access reasons.

1) The NAS layer of the terminal determines that EDT data transmission and an EDT access reason corresponding to the EDT data transmission are available, and sends first indication information to the AS layer of the terminal, wherein the first indication information is used for indicating a first access category and a first access identifier corresponding to the EDT data transmission and the EDT access reason;

Specifically, at least two new access categories are defined for wireless access of EDT Data transmission, i.e. each EDT access cause corresponds to one access category, and the EDT access cause may be mo-Data or delayotolerantaccess, etc. At least two new access categories coexist with the access category corresponding to the existing MO data transfer. The UE NAS (i.e., NAS layer of the terminal) determines that if an EDT data transmission and an EDT access cause are to be executed, the UE NAS indicates a first access category and a first access identifier corresponding to the EDT data transmission of the UE AS (i.e., AS layer of the terminal). And the UE AS executes access control operation according to the first access category, the first access identifier and the first configuration information acquired from the system broadcast message provided by the UE NAS. Specifically, the UE AS determines a 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 executes an access control operation according to the first access identifier and the first access control parameter set. The access control operation may refer to the related description of the aforementioned UAC mechanism, and will not be described in detail.

It should be noted that, in the first configuration information, an access control parameter set (i.e., UAC-barrenninfoset) corresponding to a first access category and a first access identifier needs to be added, where the first access category and the first access identifier correspond to EDT data transmission and EDT access reasons.

In this embodiment of the present application, for the above two modes, 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 the access control operation.

Further, in some optional embodiments of the present application, the method further comprises:

the terminal determines the data transmission type;

if the data transmission type belongs to EDT data transmission, the terminal determines a first access control parameter set corresponding to a first access category from the first configuration information according to the first access category corresponding to the EDT data transmission;

if the data transmission type belongs to multi-packet data transmission, the terminal determines a second access control parameter set corresponding to a second access category from the first configuration information according to the second access category corresponding to the multi-packet data transmission;

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: assuming that the data transmission of one packet belongs to EDT data transmission, the data transmission of a plurality of packets belongs to multi-packet data transmission, the terminal determines whether the EDT data transmission needs to be executed or the multi-packet data transmission needs to be executed, and if the EDT data transmission needs to be executed, a corresponding first access control parameter set is selected from the first configuration information; if multi-packet data transmission is performed, a corresponding second set of access control parameters is selected from the first configuration information.

In this embodiment of the present application, the terminal determines, according to a data transmission type (that is, EDT data transmission or multi-packet data transmission), a type of a first RRC message (hereinafter referred to as a first RRC message) sent to a network side, and 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 first RRC message sent by the terminal in the 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 packet data transmission request message. The EDT data transmission request message is an uplink RRC message carrying EDT data (or referred to as small data, or small data packets, or small packet data).

Fig. 5 is a second flow chart of an access control method provided in an embodiment of the present application, as shown in fig. 5, where the access control method includes the following steps:

step 501: the terminal determines whether the EDT data transmission performs an access control operation based on the first information.

In this embodiment of the present application, the implementation of the first information may adopt any one of the following manners:

mode one: the first information is second indication information sent by the network equipment, and the second indication information is used for indicating whether the EDT data transmission executes access control operation or not.

In an alternative embodiment, the second indication information is carried in a system broadcast message. Specifically, the base station transmits a system broadcast message carrying second indication information for indicating whether EDT data transmission performs an access control operation.

Mode two: the first mentionedThe information is preconfigured information, and the first information indicates that the EDT data transmission does not execute access control operation.

Here, the EDT data transmission may be agreed by a protocol not to perform an access control operation.

Mode three: the first information is a data transmission type; if the data transmission type belongs to EDT data transmission, the terminal determines that the access control operation is not executed; and if the data transmission type does not belong to EDT data transmission, the terminal determines to execute access control operation.

In this embodiment of the present application, when the terminal determines to perform the access control operation, the access control operation may be performed with reference to the method in fig. 4, specifically, the NAS layer of the terminal sends first indication information to the AS layer of the terminal, where the first indication information is used to indicate a target access class and a target access identifier; and the AS layer of the terminal determines a target access control parameter set corresponding to the target access category from the first configuration information, and executes access control operation according to the target access identifier and the target access control parameter set.

The technical scheme of the embodiment of the application is suitable for the LTE EDT scene and also suitable for the NR EDT scene. On the other hand, the method is suitable for EDT data transmission in a 4-step random access process and also suitable for EDT data transmission in a 2-step random access process.
