Detailed ways

In order to have a more detailed understanding of the characteristics and technical content of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present application.

Before describing in detail the cell access method provided by the embodiment of the present application, a brief description of the related technology is provided first.

At present, with people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP International Standards Organization has begun to develop 5G. The main application scenarios of 5G are: Enhance Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and Massive Machine Type Communication (mMTC).

The New Radio (NR) system can also be deployed independently. In order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services, a new Radio Resource Control (RRC) state is defined, that is, deactivation ( RRC-Inactive) state. Among them, in the idle (RRC-Idle) state, mobility is cell reselection based on terminal equipment, the paging process is initiated by the core network (Core Network, CN), and the paging area is configured by the CN. There is no terminal device context or RRC connection on the network device side. In the RRC-Inactive state, mobility is cell reselection based on terminal equipment, there is a connection between CN-NR, the context of terminal equipment exists on a certain network device, the paging process is triggered by RAN, and the paging area is based on RAN Managed by the RAN, the network equipment can know that the location of the terminal equipment is based on the paging area level of the RAN.

The strong demand for wireless communications in vertical industries is obvious to all. In order to meet the requirements of vertical industries in terms of latency, mobility, reliability, and location accuracy, the radio access network (RAN) needs to know how to access the network. Support vertical business enhancement. Among them, one way to enhance the access network's support for vertical services is to provide lower latency, more targeted, greater flexibility, and higher levels for multiple services with different requirements based on network slicing. Scalable services. More specifically, RAN slicing allows application providers to participate in the design, deployment, and operation of customized RANs to better support the business of application providers. Therefore, Release 17 (Rel-17) introduces the access network to enhance slicing, which specifically involves the following aspects:

The study item aims to investigate enhancement on RAN support of network slicing. Detailed objectives of the study item are:

1.Study mechanisms to enable UE fast access to the cell supporting the intended slice, including[RAN2]

a.Slice based cell reselection under network control

b. Slice based RACH configuration or access barring

Note: whether the existing mechanism can meet this scenario or requirement can be studied.

The network slicing in Release 15 (Rel-15) only involves the core network side. Specifically, the terminal equipment yearns for the old equipment to report its own network slicing requirements, and the network equipment selects the appropriate Access and Mobility Management Function (AMF) entity according to the network slicing requirements reported by the terminal equipment to establish the terminal The business conversation between the device and the network device.

At present, the RAN side defines a single network slice assistance information (Single Network Slice Selection Assistance Information, S-NSSAI) for each network slice. The terminal device maintains an NSSAI. NSSAI is an S-NSSAI list, and the S-NSSAI list includes up to 8 S-NSSAI.

The main purpose of access control is to control network overload, or to make special restrictions on network applications. Access control is divided into cell-level access control and terminal equipment-level access control.

The cell-level access control is mainly reflected in the special instructions broadcast by the cell system. Cell access includes barred access and non barred access, namely Cellbarred{barred,not barred}.

It can be indicated in the MIB, and the indication is valid for all PLMNs; if it is indicated that access is prohibited, all terminal devices are prohibited from accessing. For example, cellReservedForOperatorUse{Reserved,notReserved}

It can be indicated in SIB1. If the indication is reserved, it will have the effect of prohibiting access to some terminal devices (controlled by Access Identities). Such as cellReservedForOtherUse{True}

Can be indicated in SIB1. Reserved for other uses. Such as intraFreqReselection{allowed,not allowed}

In the MIB, if the current cell is barred, whether to allow reselection to the same-frequency neighboring cell. If not allowed, the restriction will be cancelled after 300s.

Access control at the terminal device level is mainly based on probabilistic access based on terminal device access trigger factors. NR bears a unified access barring mechanism that solves all use cases and scenarios, and each access attempt is classified into a designated access category. A unified model is adopted to meet the access control caused by different triggering factors, and the complexity of protocol writing is reduced. The unified access barring architecture is applicable to all terminal device states (such as RRC_IDLE, RRC_INACTIVE, or RRC_CONNECTED state).

Before introducing Unified Access Control (UAC), we first need to clarify a concept, access class (AC). Each user is randomly assigned an AC with a value of 0 to 9 and is stored in the SIM card; for some special users, they can have one or more ACs from 11 to 15, which are also stored in the SIM card. ACs from 11 to 15 generally have a higher priority, but the size of these numbers does not represent the order of priority. ACs from 0 to 9 represent ordinary users; ACs 11 are used for PLMN management; ACs 12 are used for security department applications; ACs 13 are used for public utilities; ACs 14 are used for emergency services; ACs 15 are used for PLMN staff .

The 3GPP standard also defines the access categories corresponding to all access attempts, as shown in Table 1.

Table 1

At the same time, in order to control different services or users on each access category, the standard adopts different access strategies, and the 3GPP standard defines an access identifier, as shown in Table 2.

Table 2

The network device broadcasts access control information related to the access category and access identifier, and the AS of the terminal device performs ACB checking based on the broadcast access control information and the access category and access identifier provided by the AS/NAS layer.

UAC parameters are based on the access category or PLMN configuration. As shown in Figure 1, the network device is configured with a maximum of 8 UAC-BarringInfoSets, and each access category is associated with a BarringInfoSet. A total of 64 access categories (access category 0 does not need to be configured). It can also be configured per PLMN, and each PLMN is associated with a UAC-BarringPerCatList. If it is not configured based on PLMN information, the above configuration is practical for all PLMNs.

Generally, the UAC process performed by the terminal device is triggered by the NAS layer or the access triggered by the AS layer, that is, paging and RAN-based Notification Area update (RAN-based Notification Area Update, RNAU). For paging-response access, the access category is 0, and no access control is required, and the process of accessing the network can be initiated directly. For RNAU-triggered access, the access category is 8, and access control needs to be performed.

The AS layer obtains the access control parameters according to the access category provided by the NAS layer or the access category generated by the AS layer and the access identifier. Perform access control procedures. When an event triggered by the NAS layer and an event triggered by the AS layer are triggered at the same time, the priority of setting the cause value and the access category from high to low are: RAN paging, NAS trigger event, and RNAU.

If the corresponding bit of access identities in uac-BarringForAccessIdentity is set to 0, it means that access is allowed. If the corresponding bit is set to 1, further judgment is required:

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

T390 is defined as a timer for access control, and is started for the Access category, and is specified and maintained at the AS layer. When T390 stops or times out, the access barring is lifted, and the AS layer notifies the NAS layer, which can be based on the Access category to notify the access barring to be lifted. For the handover scenario, the terminal device should obtain the effective configuration UAC configuration parameter (SIB1) from the target cell before starting the UAC process.

An optional processing procedure of the cell access method provided by the embodiment of the present application, as shown in FIG. 3, includes the following steps:

Step S201: The terminal device receives network slice information supported by the serving cell.

In some embodiments, the terminal device receives network slice information supported by the serving cell sent by the network device. The network slice information supported by the serving cell may be carried in a system broadcast message of the serving cell, for example, the network slice information supported by the serving cell is carried in an SIB message. Specifically, the SIB message may be SIB1 and so on.

In some embodiments, the network slice information may include at least one slice identifier.

In some embodiments, the network slice information may include at least one single network slice auxiliary information S-NSSAI or at least one S-NSSAI list; the S-NSSAI list includes at least one S-NSSAI. That is, the network slicing information may include one or more S-NSSAIs; or, the network slicing information may include one or more S-NSSAI lists; wherein, one S-NSSAI list may include one or more S-NSSAIs . Of course, it can also be in other forms, such as S-NSSAI combination or S-NSSAI combination list, which is not limited here.

In other embodiments, the network slice information may include at least one slice-specific access category or at least one slice-specific access category list; the slice-specific access category list includes at least one slice-specific access category list; A slice-specific access category. That is, the network slice information may include one or more slice-specific access category; or, the network slice information may include one or more slice-specific access category lists; wherein, a slice-specific access category list may include one Or multiple slice-specific access categories. Of course, it can also be in other forms, such as a slice-specific access category combination or a slice-specific access category combination list, which is not limited here.

In still other embodiments, the network slice information may also include priority information corresponding to different slice information. Specifically, the network slice information may also include: priority information of S-NSSAI or S-NSSAI list or priority information of S-NSSAI combination; and/or, slice-specific access category priority information or slice- Priority information of specific access category list or slice-specific access category combination. Wherein, the priority information may be the level of priority or the level of priority.

Of course, the UE may also save the slice information previously obtained from the network. That is, in some cases, the network slice information comes from the information saved by the UE.

In still other embodiments, the method may further include:

Step S200: The terminal device receives the access control parameter for the network slice information.

In some embodiments, the terminal device receives an access control parameter for the network slice information sent by the network device; the access control parameter may be carried in a system broadcast message of the serving cell, such as a SIB message; Incoming control parameters can also be carried in RRC signaling and NAS information. If the system broadcast message and dedicated signaling of the serving cell both carry access control parameters, the access control eucalyptus carried in the dedicated signaling is used as the access control parameter for the network slice information. That is, when the access control parameter is carried in the system message and RRC signaling of the serving cell, the access control parameter carried in the RRC signaling is the access control parameter for the network slice information Or, in the case where the access control parameter is carried in the system message and NAS information of the serving cell, the access control parameter carried in the NAS information is the access control parameter for the network slice information .

In specific implementation, each S-NSSAI or each slice-specific access category can correspond to one access control parameter, or the S-NSSAI as a whole corresponds to one access control parameter, or all slice-specific access control parameters. The access category as a whole corresponds to an access control parameter.

In specific implementation, when the access control parameter is indicated to the terminal device by the network device through dedicated RRC signaling, it may be indicated to the terminal device through, for example, an RRC release message or an RRC reconfiguration message. The terminal device saves the access control parameters for subsequent access control use.

When the access control parameter is indicated to the terminal device by the access control parameter through the NAS information, it can be indicated to the terminal device through a message such as a registration or reconfiguration update command (configuration update command). The terminal device saves the access control parameters for subsequent access control use.

In some embodiments, the access control parameters may include: access barring parameters and/or access weight parameters. Wherein, the value of the access weight parameter may be 1.

In some embodiments, the access barring parameter may include: bar factor and/or barring time.

In some embodiments, the access control parameter may include a first access control parameter and a second access control parameter, and the first access control parameter is used when allowing the terminal device to perform cell access, The second access control parameter is used when the terminal device is prohibited from performing cell access. Of course, the first access control parameter and the second access control parameter may also be the same.

In some embodiments, when the network slice information includes at least one S-NSSAI, all S-NSSAIs correspond to one access control parameter; or, the network slice information includes at least one S-NSSAI list In the case of, one S-NSSAI list corresponds to one access control parameter; or, in the case that the network slice information includes at least one S-NSSAI combination, one S-NSSAI combination corresponds to one access control parameter . When the network slice information includes at least one slice-specific access category, all slice-specific access categories correspond to one of the access control parameters; or, the network slice information includes at least one slice-specific access category list In the case of, a slice-specific access category list corresponds to one of the access control parameters; or, when the network slice information includes at least one slice-specific access category combination, one slice-specific access category combination corresponds to one The access control parameters.

In some other implementation manners, when the network slice information includes at least one S-NSSAI, each S-NSSAI corresponds to one of the access control parameters; or, when the network slice information includes at least one S-NSSAI, In the case of the NSSAI list, each subset of the S-NSSAI list corresponds to one of the access control parameters; or, in the case that the network slice information includes at least one S-NSSAI combination, each S-NSSAI combination The subset corresponds to one said access control parameter. When the network slice information includes at least one slice-specific access category, each slice-specific access category corresponds to one access control parameter; or, the network slice information includes at least one slice-specific access category In the case of a list, each subset of the slice-specific access category list corresponds to one access control parameter. Wherein, when each subset of the slice-specific access category list corresponds to one of the access control parameters, if a slice-specific access category list includes N slice-specific access categories, of which, among the N slice-specific access categories The M slice-specific access categories are the first subset of the slice-specific access category list, and (NM) slice-specific access categories of the N slice-specific access categories are the second subset of the slice-specific access category list. Then the first subset corresponds to one access control parameter, that is, the N slice-specific access categories in the first subset correspond to one access control parameter; the second subset corresponds to another access control parameter, that is, the second subset The (NM) slice-specific access category within corresponds to another access control parameter. Or, in the case where the network slice information includes at least one slice-specific access category combination, each subset of the slice-specific access category combination corresponds to one said access control parameter.

Step S202: The terminal device performs cell access based on the network slice information.

In some embodiments, the terminal device performs cell access based on at least one of attribute information and access control parameters of the terminal device, and the network slice information. That is, the terminal device may perform cell access based on the attribute information of the terminal device and the network slice information, the terminal device may also perform cell access based on the access control parameters and the network slice information, and the terminal device may also perform cell access based on the The attribute information, access control parameters, and the network slice information of the terminal device perform cell access.

Wherein, the attribute information of the terminal device includes at least one of the following: whether the terminal device has the ability to support the network slicing information, whether the terminal device supports the network supported by the serving cell sent by the network device At least one item in the slice information, whether the upper layer of the terminal device indicates the network slice information corresponding to the requested network slice, whether the upper layer of the terminal device indicates the network slice information corresponding to the selected network slice, the Whether the upper layer of the terminal device has requested a network slice corresponding to at least one item in the network slice information, and whether the upper layer of the terminal device has selected a network slice corresponding to at least one item in the network slice information.

The network slice information may include S-NSSAI or S-NSSAI list or S-NSSAI combination, and/or the network slice information may include slice-specific access category or slice-specific access category list or slice-specific access category In the case of combination, the attribute information of the terminal device includes at least one of the following:
