Description

一种接入控制的方法、设备及计算机存储介质Method, device and computer storage medium for access control 技术领域Technical field
本发明实施例涉及无线通信技术领域，尤其涉及一种接入控制的方法、设备及计算机存储介质。Embodiments of the present invention relate to the field of wireless communications technologies, and in particular, to a method, device, and computer storage medium for access control.
背景技术Background technique
在长期演进(LTE，Long Term Evolution)***中，为了避免网络过载现象的发生，引入了接入控制准入(ACB，Access Control Barring)机制。而随着通信技术的发展，第五代移动通信技术(5G，5th Generation)的研究也已经展开。5G的无线接入叫New Radio，简称NR。在5G NR中，引入了网络切片(network slice)的概念，不同的切片在无线接入网络(RAN，Radio)Access Network)侧和核心网(CN，Core Network)侧具有相应的切片实例(instance)，由于不同的切片实例instance之间具有一定的隔离特性。In the Long Term Evolution (LTE) system, an Access Control Barring (ACB) mechanism is introduced to avoid network overload. With the development of communication technology, the research of the fifth generation mobile communication technology (5G, 5th Generation) has also begun. 5G wireless access is called New Radio, referred to as NR. In the 5G NR, the concept of a network slice is introduced, and different slices have corresponding slice instances (instance on the radio access network (RAN, Radio) Access Network) side and the core network (CN, Core Network) side. ), because of the isolation characteristics between different slice instances.
目前，终端需要进入连接态并且进行附着attach后，才能够获取网络切片信息，网络侧只能基于终端获取网络切片信息的行为来针对网络切片进行接入控制。因此，当终端处于由空闲态转为连接态的过程中，如果目标网络切片已经过载，网络侧也只能在终端进入连接态之后，再根据连接态终端发送的消息中所携带的目标网络切片标识针对该目标网络切片进行接入控制，释放release终端。从而增加了终端与网络侧之间的信令资源消耗，在终端与网络侧之间产生了信令资源的浪费，也增加了接入控制的时延。At present, the terminal needs to enter the connected state and attach the attached to obtain the network slice information. The network side can only perform access control on the network slice based on the behavior of the terminal acquiring the network slice information. Therefore, when the terminal is in the process of transition from the idle state to the connected state, if the target network slice is overloaded, the network side can only perform the target network slice carried in the message sent by the connected terminal after the terminal enters the connected state. The identifier performs access control on the target network slice, and releases the release terminal. Therefore, the signaling resource consumption between the terminal and the network side is increased, and signaling resource waste is generated between the terminal and the network side, and the delay of the access control is also increased.

具体实施方式Detailed ways
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。The embodiments of the present invention are described in detail below with reference to the accompanying drawings.
目前在5G***的相关技术中提出了网络切片slice的概念；其本质上就是将运营商的物理网络在逻辑上划分为多个虚拟网络，每一个虚拟网络根据不同的服务需求进行划分，比如可以根据时延、带宽、优先级、安全性和可靠性等服务需求信息进行划分，从而能够灵活的应对不同的网络应用场景。因此，不同网络切片(也就是虚拟网络)之间相互隔离，以使得一个网络切片的错误或故障不会影响到其它网络切片的正常通信。At present, the concept of network slice slice is proposed in the related technology of 5G system; in essence, the physical network of the operator is logically divided into multiple virtual networks, and each virtual network is divided according to different service requirements, for example, It is divided according to service demand information such as delay, bandwidth, priority, security, and reliability, so that it can flexibly respond to different network application scenarios. Therefore, different network slices (ie, virtual networks) are isolated from each other such that a network slice error or failure does not affect normal communication of other network slices.
基于上述针对网络切片的说明，可以得知，网络切片类型可以包括接入网络切片Access Network slice、核心网络切片Core Network slice以及数据网络及服务切片Data Network and Service slice。所以，针对网络切片进行接入控制AC，所涉及到的网络侧设备包括5G***的无线接入网设备，比如gNB；还可以包括5G***的核心网设备，比如核心访问与移动性管理(AMF，Core Access and Moblity Management Function)。因此，本发明实施例的技术方案可以非典型性地应用于图1所示的网络架构场景，在该场景中，终端可以接入到无线接入网RAN后，通过N2接口接入到5G核心网；也可以直接通过N1接口与5G核心网进行连接。需要说明的是，N1是UE和AMF的NAS信令接口，N2是gNB和AMF之间的接口。另外，在图1所示的场景中，无线接入网RAN设备可以包括gNB；5G核心网设备可以包括AMF；用户设备(UE，User Equipment)可以包括蜂窝电话、智能电话、会话发起协议(SIP)电话、膝上型计算机、个人数字助理(PDA)、卫星无线电、全球定位***、多媒体设备、视频设备、数字音频播放器(例如，MP3播放器)、照相机、游戏控制台、平板计算机、或任何其它具有类似功能的设备。与此同时，用户设备还可以被本领域技术人员称为终端、移动站、订户站、移动单元、订户单元、无线单元、远程单元、移动设备、无线设备、无线通信设备、远程设备、移动订户站、接入终端、移动终端、无线终端、远程终端、手持机、用户代理、移动客户端、客户端、或某种其它适当的术语。Based on the foregoing description of the network slice, it can be known that the network slice type can include an access network slice Access Network slice, a core network slice Core Network slice, and a data network and a service slice Data Network and Service slice. Therefore, the access control AC is performed for the network slice, and the network side devices involved include a 5G system radio access network device, such as a gNB; and may also include a 5G system core network device, such as core access and mobility management (AMF). , Core Access and Moblity Management Function). Therefore, the technical solution of the embodiment of the present invention can be applied to the network architecture scenario shown in FIG. 1 in a typical manner, in which the terminal can access the radio access network RAN and access the 5G core through the N2 interface. Network; can also directly connect to the 5G core network through the N1 interface. It should be noted that N1 is the NAS signaling interface of the UE and the AMF, and N2 is the interface between the gNB and the AMF. In addition, in the scenario shown in FIG. 1, the radio access network RAN device may include a gNB; the 5G core network device may include an AMF; and the user equipment (UE, User Equipment) may include a cellular phone, a smart phone, and a session initiation protocol (SIP). a phone, laptop, personal digital assistant (PDA), satellite radio, global positioning system, multimedia device, video device, digital audio player (eg, MP3 player), camera, game console, tablet, or Any other device with similar functionality. At the same time, the user equipment may also be referred to by those skilled in the art as a terminal, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber. Station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable terminology.
基于图1所示的网络架构，在目前相关的网络切片机制，主要针对网 络侧以及UE的非接入层(NAS，Non-Access Stratum)，但是UE的接入层(AS，Access Stratum)对于网络切片来说几乎是透明的，比如，包括主信息块(MIB，Master Information Block)、剩余最小***信息(RMSI，Remaining Minimum System Information)以及其他***信息在内的NR***信息均没有携带网络切片信息。基于此，空闲IDLE态的UE无法通过读取***信息来获知网络侧提供的网络切片服务。如果UE期望获得网络切片相关的服务，就需要进入连接态并进行附着(attach)后才可以从网络侧实体如AMF获取网络切片信息。并且，在目前相关的第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)标准Rel-15版本中，物理随机接入信道(PARCH，Physical Random Access CHannel)和网络切片之间也不支持直接的映射，因此，UE在通过PRACH进行无线资源控制(RRC，Radio Resource Control)信令交互的过程中也无法基于PRACH针对不同的网络切片进行ACB。Based on the network architecture shown in Figure 1, the current related network slicing mechanism is mainly for the network side and the non-access stratum (NAS, Non-Access Stratum) of the UE, but the access layer (AS, Access Stratum) of the UE is Network slicing is almost transparent. For example, NR system information including MIB (Master Information Block), Remaining Minimum System Information (RMSI), and other system information does not carry network slices. information. Based on this, the UE in the idle IDLE state cannot learn the network slice service provided by the network side by reading the system information. If the UE desires to obtain the network slice related service, it needs to enter the connection state and attach to obtain the network slice information from the network side entity such as AMF. Moreover, in the current Rel-15 version of the 3rd Generation Partnership Project (3GPP), the physical random access channel (PARCH, Physical Random Access CHannel) and the network slice do not support direct Therefore, the UE cannot perform ACB for different network slices based on the PRACH in the process of performing radio resource control (RRC) signaling interaction through the PRACH.
针对上述相关网络切片机制的阐述，可以得知：针对IDLE态的UE，无法结合网络切片slice的信息进行ACB。理由在于：For the description of the above-mentioned related network slicing mechanism, it can be known that the UE for the IDLE state cannot perform ACB in combination with the information of the network slice slice. The reason is:
首先，切片信息和PARCH资源很难建立对应关系，RACH资源本身很有限，而支持的切片有可能很多，因此，不同切片的PARCH无法基于不同的随机接入信道(RACH，Random Access CHannel)参数进行ACB。Firstly, it is difficult to establish the correspondence between the slice information and the PARCH resource. The RACH resource itself is very limited, and the supported slice is likely to be many. Therefore, the PARCH of different slices cannot be based on different random access channel (RACH, Random Access CHannel) parameters. ACB.
其次，由于现有的用于标识网络切片的网络切片选择辅助信息(NSSAI，Network Slice Selection Assistance Information)较长，包括服务及切片类型(SST，Service and Slice Type)信息和服务及切片区分(SSD，Service and Slice Differentiator)，SST与SSD两者的总长度达到了32比特，而每个UE目前能够并行支持8个网络切片，因此，网络切片的标识信息NSSAI的总长度最长可以达到32×8＝256字节,远远超过了公共控制信道(CCCH，Common Control Channel)信道上针对第三类消息MSG3所设定的48比特的限制。因此，无法基于MSG3针对网络切片实施ACB。如此则会导致以下情况发生：如果某一个网络切片已经过载overload，则在UE发送的MSG3，比如RRC连接请求(RRC Connection Req)消息或者RRC连接恢复(RRC Connection Resume)消息中无法承载网络切片信息，从而导致网络侧并不能够依据过载的网络切片拒绝该请求，而是继续回复第四类消息MSG4，比如RRC连接建立(RRC Connection Establishment)消息；UE在接收到MSG4后继续发送第五类消息MSG5，并在MSG5中携带网络切片标识；直到此时，网络侧才能根据网络切片标识进行ACB，发现网络切片过载后，网络侧才能够将终端的RRC连接释放release。在这一过程中，UE与网络侧之间交互的MSG4以及后续的MSG5可以认为是增加了信令资源 的消耗，造成了没有必要的信令资源浪费。Secondly, the existing Network Slice Selection Assistance Information (NSSAI) for identifying network slices is long, including service and slice type (SST) information and service and slice differentiation (SSD). , Service and Slice Differentiator), the total length of both SST and SSD reaches 32 bits, and each UE can currently support 8 network slices in parallel. Therefore, the total length of the network slice identification information NSSAI can be up to 32×. 8 = 256 bytes, far exceeding the 48-bit limit set for the third type of message MSG3 on the Common Control Channel (CCCH) channel. Therefore, ACB cannot be implemented for network slices based on MSG3. This may result in the following situation: if a network slice has been overloaded, the network slice information cannot be carried in the MSG3 sent by the UE, such as an RRC Connection Req message or an RRC Connection Resume message. Therefore, the network side is not able to reject the request according to the overloaded network slice, but continues to reply to the fourth type message MSG4, such as an RRC Connection Establishment message; the UE continues to send the fifth type message after receiving the MSG4. MSG5 carries the network slice identifier in MSG5. Until then, the network side can perform ACB according to the network slice identifier. After the network slice is overloaded, the network side can release the RRC connection of the terminal. In this process, the MSG4 and the subsequent MSG5 that the UE interacts with the network side can be considered to increase the consumption of signaling resources, resulting in unnecessary waste of signaling resources.
为了能够较MSG5消息发送之前针对网络切片进行接入控制，本发明实施例中提供了一种接入控制的方法，该方法可以应用于UE，参见图2，该方法可以包括：In order to enable the access control to be performed on the network slice before the MSG5 message is sent, the method of the access control is provided in the embodiment of the present invention. The method may be applied to the UE. Referring to FIG. 2, the method may include:
S201：UE与网络侧设备建立短切片标识(SSI，Shortened Slice Index)与网络切片选择辅助信息NSSAI之间的映射关系；其中，具有映射关系的短切片标识SSI与网络切片选择辅助信息NSSAI均指示相同的网络切片；且所述SSI的长度短于所述NSSAI；S201: The mapping between the short slice identifier (SSI) and the network slice selection assistance information NSSAI is established by the UE and the network side device. The short slice identifier SSI and the network slice selection assistance information NSSAI with the mapping relationship are both indicated. The same network slice; and the length of the SSI is shorter than the NSSAI;
S202：UE基于所述映射关系将目标网络切片的SSI承载于上行信令中；S202: The UE carries the SSI of the target network slice in the uplink signaling according to the mapping relationship.
S203：UE发送承载有目标网络切片的SSI的上行信令；其中，所述上行信令用于所述网络侧设备基于所述SSI针对所述目标网络切片进行接入控制。S203: The UE sends uplink signaling that carries the SSI of the target network slice, where the uplink signaling is used by the network side device to perform access control for the target network slice based on the SSI.
基于图2所示的技术方案，UE在与网络侧设备，比如接入设备(如gNB)或核心网设备(如AMF)建立完成短切片标识SSI与网络切片选择辅助信息NSSAI之间的映射关系之后，当UE处于空闲IDLE态或非激活INACTIVE态时，能够将长度较短的SSI承载于上行信令(比如第三消息MSG3)中向网络侧设备发送，使得网络侧设备能够使用接收到的SSI针对网络切片进行接入控制。相较于目前相关技术，可以使得网络切片过载时，网络侧设备无需等到接收MSG5之后才能够根据MSG5所承载的NSSAI针对网络切片进行ACB，能够提前针对网络切片进行ACB。不仅降低信令资源消耗，避免了UE与网络侧之间信令资源的浪费，而且还减少了针对网络切片进行接入控制的时延。Based on the technical solution shown in FIG. 2, the UE establishes a mapping relationship between the short slice identifier SSI and the network slice selection auxiliary information NSSAI with a network side device, such as an access device (such as a gNB) or a core network device (such as an AMF). Then, when the UE is in the idle IDLE state or the inactive INACTIVE state, the short-length SSI can be sent to the network side device in the uplink signaling (such as the third message MSG3), so that the network side device can use the received The SSI performs access control for the network slice. Compared with the current related technologies, when the network slice is overloaded, the network side device can perform ACB for the network slice according to the NSSAI carried by the MSG5 without waiting for the MSG5 to receive the ACB. Not only the signaling resource consumption is reduced, the signaling resource waste between the UE and the network side is avoided, and the delay for access control of the network slice is also reduced.
对于图2所示的技术方案，在具体实现过程中，网络侧设备既可以包括无线接入网设备，如gNB；也可以包括核心网设备，如AMF；因此，所述上行信令可以包括RRC信令或NAS信令。具体来说，当UE处于空闲IDLE态或非激活INACTIVE态的情况下，由gNB进行接入控制，因此，上行信令具体可以是RRC信令，包括MSG3或者第五消息MSG5或者其他RRC消息；当由AMF进行接入控制，此时上行信令具体可以是NAS信令。For the technical solution shown in FIG. 2, in a specific implementation process, the network side device may include a radio access network device, such as a gNB, and may also include a core network device, such as an AMF; therefore, the uplink signaling may include an RRC. Signaling or NAS signaling. Specifically, when the UE is in the idle IDLE state or the inactive INACTIVE state, the access control is performed by the gNB. Therefore, the uplink signaling may specifically be RRC signaling, including the MSG3 or the fifth message MSG5 or other RRC message. When access control is performed by the AMF, the uplink signaling may specifically be NAS signaling.
在针对图2所示方案的一种可能的实现方式中，优选地，对于步骤S201所述的UE与网络侧设备建立短切片标识SSI与网络切片选择辅助信息NSSAI之间的映射关系，可以包括：In a possible implementation manner of the solution shown in FIG. 2, the mapping relationship between the short slice identifier SSI and the network slice selection assistance information NSSAI of the UE and the network side device, which is described in step S201, may be included. :
UE向网络侧设备发送注册请求；其中，所述注册请求中包括待注册的网络切片信息；The UE sends a registration request to the network side device, where the registration request includes network slice information to be registered;
UE接收网络侧设备针对所述注册请求中的待注册的网络切片信息所返回的注册回应消息；其中，所述注册回应消息包括待注册的网络切片的 NSSAI与SSI之间的映射关系。The UE receives a registration response message returned by the network side device for the network slice information to be registered in the registration request, where the registration response message includes a mapping relationship between the NSSAI and the SSI of the network slice to be registered.
通过上述优选地的实现方式，网络侧设备可以根据终端期望注册的网络切片信息建立NSSAI与SSI之间的对应关系，并将该对应关系返回至UE。致使在UE侧以及网络侧均建立了相同的SSI与NSSAI之间的映射关系，从而使得UE在通过SSI来指示目标网络切片时，网络侧设备可以通过承载有SSI的上行信令获知目标网络切片，并根据目标网络切片的负载情况进行接入控制。Through the above-mentioned preferred implementation manner, the network side device may establish a correspondence between the NSSAI and the SSI according to the network slice information that the terminal desires to register, and return the corresponding relationship to the UE. The mapping between the same SSI and the NSSAI is established on the UE side and the network side, so that when the UE indicates the target network slice through the SSI, the network side device can learn the target network slice by using the uplink signaling that carries the SSI. And perform access control according to the load condition of the target network slice.
此外，当UE获知短切片标识SSI与NSSAI之间的映射关系之后，还可以基于所述目标网络切片的SSI通过确定是否发送所述承载有SSI的上行信令来针对SSI所指示的目标网络切片进行接入控制。In addition, after the UE learns the mapping relationship between the short slice identifier SSI and the NSSAI, the target network slice indicated by the SSI may also be determined based on the SSI of the target network slice by determining whether to send the uplink signaling that carries the SSI. Perform access control.
举例来说，UE在生成了携带有目标网络切片的SSI的MSG3后，UE可以通过目标网络切片的SSI决定是否发送上行信令的方式来对目标网络切片进行接入控制。比如，UE可以是根据SSI的优先级，随后依概率决定是否发送携带有SSI的MSG3，该概率与对应的接入类型有关。For example, after the UE generates the MSG3 carrying the SSI of the target network slice, the UE may perform access control on the target network slice by using the SSI of the target network slice to determine whether to send the uplink signaling. For example, the UE may be based on the priority of the SSI, and then decide whether to send the MSG3 carrying the SSI according to the probability, and the probability is related to the corresponding access type.
基于图2所示的技术方案相同的发明构思，参见图3，其示出了本发明实施例提供的一种接入控制的方法，该方法可以应用于网络侧设备。可以理解地，该网络侧设备既可以包括无线接入网设备，如gNB；也可以包括核心网设备，如AMF；该方法可以包括：Based on the same inventive concept of the technical solution shown in FIG. 2, referring to FIG. 3, a method for access control according to an embodiment of the present invention is shown, which can be applied to a network side device. It can be understood that the network side device may include a radio access network device, such as a gNB, and may also include a core network device, such as an AMF. The method may include:
S301：网络侧设备与UE建立短切片标识(SSI，Shortened Slice Index)与网络切片选择辅助信息NSSAI之间的映射关系；其中，具有映射关系的短切片标识SSI与网络切片选择辅助信息NSSAI均指示相同的网络切片；且所述SSI的长度短于所述NSSAI；S301: The mapping between the short slice identifier (SSI) and the network slice selection assistance information NSSAI is set up by the network side device and the UE, where the short slice identifier SSI and the network slice selection assistance information NSSAI are both indicated. The same network slice; and the length of the SSI is shorter than the NSSAI;
S302：网络侧设备接收UE发送的承载有SSI的上行信令；S302: The network side device receives the uplink signaling that is sent by the UE and carries the SSI.
S303：网络侧设备针对所述上行信令中承载的SSI所指示的网络切片，按照设定的接入控制策略进行接入控制。S303: The network side device performs access control according to the set access control policy for the network slice indicated by the SSI carried in the uplink signaling.
基于图3所示的技术方案，网络侧设备在与UE建立完成短切片标识SSI与网络切片选择辅助信息NSSAI之间的映射关系之后，使用接收到的承载有SSI的上行信令针对网络切片进行接入控制。相较于目前相关技术，可以使得网络切片过载时，网络侧设备无需等到接收MSG5之后才能够根据MSG5所承载的NSSAI针对网络切片进行ACB，能够提前针对网络切片进行ACB。不仅降低信令资源消耗，避免了UE与网络侧之间信令资源的浪费，而且还减少了针对网络切片进行接入控制的时延。Based on the technical solution shown in FIG. 3, after establishing a mapping relationship between the short slice identifier SSI and the network slice selection assistance information NSSAI, the network side device performs the network slice using the received uplink signaling carrying the SSI. Access control. Compared with the current related technologies, when the network slice is overloaded, the network side device can perform ACB for the network slice according to the NSSAI carried by the MSG5 without waiting for the MSG5 to receive the ACB. Not only the signaling resource consumption is reduced, the signaling resource waste between the UE and the network side is avoided, and the delay for access control of the network slice is also reduced.
由于该网络侧设备既可以包括无线接入网设备，如gNB；也可以包括核心网设备，如AMF；因此，所述上行信令可以包括RRC信令或NAS信令。具体来说，当UE处于空闲IDLE态或非激活INACTIVE态的情况下， 由gNB进行接入控制，因此，上行信令具体可以是RRC信令，包括或MSG3或者第五消息MSG5或者其他RRC消息；当由AMF进行接入控制，此时上行信令具体可以是NAS信令。The network side device may include a radio access network device, such as a gNB, and may also include a core network device, such as an AMF. Therefore, the uplink signaling may include RRC signaling or NAS signaling. Specifically, when the UE is in the idle IDLE state or the inactive INACTIVE state, the access control is performed by the gNB. Therefore, the uplink signaling may specifically be RRC signaling, including the MSG3 or the fifth message MSG5 or other RRC message. When the access control is performed by the AMF, the uplink signaling may specifically be NAS signaling.

通过上述优选地的实现方式，网络侧设备可以根据终端期望注册的网络切片信息建立NSSAI与SSI之间的对应关系，并将该对应关系返回至UE。致使在UE侧以及网络侧均建立了相同的SSI与NSSAI之间的映射关系，从而使得后续UE在通过SSI来指示目标网络切片时，网络侧设备可以通过承载有SSI的上行信令获知目标网络切片，并根据目标网络切片的负载情况进行接入控制。Through the above-mentioned preferred implementation manner, the network side device may establish a correspondence between the NSSAI and the SSI according to the network slice information that the terminal desires to register, and return the corresponding relationship to the UE. The mapping relationship between the same SSI and the NSSAI is established on the UE side and the network side, so that the network-side device can obtain the target network through the uplink signaling carrying the SSI when the subsequent UE indicates the target network slice through the SSI. Slice and perform access control based on the load of the target network slice.

具体来说，网络侧设备根据所述SSI获知所指示的网络切片后，可以按照该网络切片的负载来控制UE是否能够接入。详细来说，网络侧设备可以针对负载情况设置用于指示过载overload的负载阈值；相应于网络切片的负载超过该负载阈值，释放release该UE的接入；相应于网络切片的负载没有超过该负载阈值，允许该UE接入该网络切片。Specifically, after the network side device learns the indicated network slice according to the SSI, the network side device may control whether the UE can access according to the load of the network slice. In detail, the network side device may set a load threshold for indicating an overload load for a load condition; release a release of the UE corresponding to a load of the network slice exceeding the load threshold; and the load corresponding to the network slice does not exceed the load A threshold that allows the UE to access the network slice.

工业实用性Industrial applicability
本发明实施例中，UE在与网络侧设备，比如接入设备(如gNB)或核心网设备(如AMF)建立完成短切片标识SSI与网络切片选择辅助信息NSSAI之间的映射关系之后，当UE处于空闲IDLE态或非激活INACTIVE态时，能够将长度较短的SSI承载于非连接态所适用的上行信令(比如第三消息MSG3)中向网络侧设备发送，使得网络侧设备能够使用接收到的SSI针对网络切片进行接入控制。相较于目前相关技术，可以使得网络切片过载时，网络侧设备无需等到接收MSG5之后才能够根据MSG5所承载的NSSAI针对网络切片进行ACB，能够提前针对网络切片进行ACB。不仅降低信令资源消耗，避免了UE与网络侧之间信令资源的浪费，而且还减少了针对网络切片进行接入控制的时延。In the embodiment of the present invention, after establishing a mapping relationship between the short slice identifier SSI and the network slice selection auxiliary information NSSAI, the UE establishes a mapping relationship between the short slice identifier SSI and the network slice selection auxiliary information NSSAI, such as an access device (such as a gNB) or a core network device (such as an AMF). When the UE is in the idle IDLE state or the inactive INACTIVE state, the short-length SSI can be sent to the network side device in the uplink signaling (such as the third message MSG3) to which the non-connected state is applicable, so that the network side device can be used. The received SSI performs access control for the network slice. Compared with the current related technologies, when the network slice is overloaded, the network side device can perform ACB for the network slice according to the NSSAI carried by the MSG5 without waiting for the MSG5 to receive the ACB. Not only the signaling resource consumption is reduced, the signaling resource waste between the UE and the network side is avoided, and the delay for access control of the network slice is also reduced.
