Description

Method, device and terminal for realizing network slice admission control

Technical field

本公开涉及但不限于移动通信技术，尤指一种实现网络切片接纳控制的方法及装置和终端。The present disclosure relates to, but is not limited to, mobile communication technologies, and more particularly to a method and apparatus and terminal for implementing network slice admission control.

Background technique

移动通信的发展日新月异，渗透到人们工作、社交、生活的各个方面，给人们的生活方式、工作方式以及社会政治、经济等各方面都带来了巨大的影响。人类社会进入了信息化时代，各个方面业务应用需求呈现爆发式增长，在未来的移动网络，不仅仅提供人与人之间的通信，还要为物联网海量设备提供服务。比如：虚拟现实、高清视频等有超高速率服务需求的业务，速率可以达到现在的10～100倍；再如：车联网等有低延时服务需求的业务，端到端时延可以缩短5倍；又如：物联网可以接入现在的1000倍数量的业务，而电池寿命也可以延长到现在的10倍等。The development of mobile communication is changing with each passing day. It penetrates into all aspects of people's work, social and life, and has a tremendous impact on people's lifestyle, working methods, social politics, and economy. Human society has entered the information age, and the demand for business applications in all aspects has exploded. In the future, mobile networks will not only provide communication between people, but also provide services for massive devices of the Internet of Things. For example, virtual reality, high-definition video and other services with ultra-high-speed service requirements can reach 10 to 100 times the current rate; for example, services such as car networking with low-latency service requirements, end-to-end delay can be shortened by 5 Double; another example: the Internet of Things can access the current 1000 times the number of services, and the battery life can be extended to 10 times now.

差异化的商业模式和业务需求给未来无线移动宽带系统在频率、技术以及运营等各方面都带来了巨大的挑战，传统的通信网络即接入网(RAN，Residential Access Network)+核心网(CORE)的方式越来越无法满足所有场景。而为每一种场景都建设专网，又会造成大量的资源浪费。Differentiated business models and business needs bring great challenges to the future wireless mobile broadband system in terms of frequency, technology and operation. The traditional communication network is the RAN (Residential Access Network) + core network ( The CORE) approach is increasingly unable to satisfy all scenarios. The construction of a private network for each scenario will result in a large amount of waste of resources.

网络功能虚拟化(NFV，Network Function Virtualization)技术的发展，使得运营商为不同的业务需求构建不同的虚拟网络成为可能。网络切片就是基于通用物理基础设施，对网络进行逻辑上的定义和划分，以形成端到端的虚拟网络，每个虚拟网络具备不同的功能特点，来动态的满足各种各样的需求和商业模式。The development of Network Function Virtualization (NFV) technology has made it possible for operators to build different virtual networks for different business needs. Network slicing is based on a common physical infrastructure, logically defining and dividing the network to form an end-to-end virtual network. Each virtual network has different functional characteristics to dynamically meet various needs and business models. .

一个典型的网络切片包括一组虚拟化的接入网功能和核心网功能。网络切片由运营商根据需求和策略进行构建，一个网络切片包括的功能也由运营商根据需求和策略决定。比如，某些网络切片除了包括控制面功能外还可以包括专用的转发面功能；再如，某些网络切片可能只包括一些基本的控制面功能。A typical network slice includes a set of virtualized access network functions and core network functions. The network slice is built by the operator according to the requirements and policies. The functions included in a network slice are also determined by the operator according to the requirements and policies. For example, some network slices may include dedicated forwarding plane functions in addition to control plane functions; for example, some network slices may include only some basic control plane functions.

图1为相关技术中的网络切片的示意图。如图1所示，示例了一个通用网络(Common Network)，以及定制化的类型A(Type A)、Type B、Type C三种网络切片类别。Common Network为通用的业务提供服务；而定制化的网络切片，提供三种不同类型的服务，比如：类型A为超高速业务如视频业务，虚拟现实等；类型B为突发小业务数据业务如QQ、微信等；类型C为低时延超可靠业务如车联网，智能电网等；每一种类型根据一些差异如业务需求和商业模式等不同，生成不同的网络切片实例，比如：类型A进行视频业务，根据视频类型对业务速率的要求，分为支持普通视频的切片A1，支持高清视频的切片A2等。一个网络切片构成一个虚拟网络，为用户终端(UE)提供一种特定的移动网络接入服务。FIG. 1 is a schematic diagram of a network slice in the related art. As shown in FIG. 1, a common network (Common Network) and three types of network slice types of Type A, Type B, and Type C are customized. The Common Network provides services for general-purpose services; and customized network slicing provides three different types of services, such as: Type A is ultra-high-speed services such as video services, virtual reality, etc.; Type B is bursty small business data services such as QQ, WeChat, etc.; Type C is low-latency ultra-reliable services such as car networking, smart grid, etc.; each type generates different network slice instances according to some differences such as business requirements and business models, such as: Type A The video service is classified into a slice A1 that supports normal video and a slice A2 that supports high-definition video according to the requirements of the video type. A network slice forms a virtual network that provides a specific mobile network access service for the user terminal (UE).

由于网络存在切片，在相关技术中，并未披露如何配置基于切片的接纳控制。当某个网络切片处于拥塞状态时，如何提供对归属不同切片的不同业务请求的用户采用接纳控制在相关技术中也没有提供相应的处理方式。Since the network has slices, in the related art, how to configure slice-based admission control is not disclosed. When a network slice is in a congested state, how to provide admission control for users who have different service requests belonging to different slices does not provide a corresponding processing method in the related art.

The base station, the base station modifies the admission control type mapping rule according to at least one of the obtained configuration information and the congestion information, and sends the mapping rule to the UE. The modification can be performed according to the configuration of the base station network management.

方式四：Method 4:

网络配置发生变化时，基站修改网络切片标识对应的接纳控制类型，以及接纳控制类型对应的接纳控制参数。When the network configuration changes, the base station modifies the admission control type corresponding to the network slice identifier and the admission control parameter corresponding to the admission control type.

当配置发生变化如网管配置网络切片、和网络切片发生拥塞其中至少之一时，核心网通过地面侧接口向基站报告某网络切片配置和拥塞其中至少之一。网络切片的信息如标识和配置信息和拥塞信息其中至少之一可以通过NG-C接口或S1接口的消息发送给基站，该消息可以重用现有的消息或者新建立消息。When the configuration changes, such as the network management network slice and the network slice congestion, the core network reports at least one of a network slice configuration and congestion to the base station through the ground side interface. At least one of the information of the network slice, such as the identification and configuration information and the congestion information, may be sent to the base station through a message of the NG-C interface or the S1 interface, and the message may reuse the existing message or the newly established message.

步骤201：基站将确定出的网络配置发生变化的网络切片对应的接纳控制类型及其对应的接纳控制参数通知给终端。Step 201: The base station notifies the terminal of the admission control type corresponding to the determined network slice whose network configuration is changed and the corresponding admission control parameter.

对应于步骤200中的方式二，映射需要考虑业务请求类型的网络切片属性，不同网络切片的相同业务可以映射为相同的接纳控制类型，也可以映射为不相同的接纳控制类型。接纳控制类型为基站广播的接纳控制类型的一个或多个。Corresponding to the second mode in step 200, the mapping needs to consider the network slice attribute of the service request type. The same service of different network slices may be mapped to the same admission control type, or may be mapped to different admission control types. The admission control type is one or more of the admission control types broadcast by the base station.

终端的非接入层或应用层将终端发起的业务请求映射为收到的信息中的接纳控制类型，并根据接纳控制类型对应的接纳控制参数执行接纳控制；如果终端发起的业务归属步骤200中的网络配置发生变化的网络切片，那么，根据基站广播的网络切片标识及对应的接纳控制类型，以及接纳控制类型对应的接纳控制参数执行接纳控制；或者，The non-access stratum or the application layer of the terminal maps the service request initiated by the terminal to the admission control type in the received information, and performs admission control according to the admission control parameter corresponding to the admission control type; if the service initiated by the terminal belongs to step 200 The network configuration changes the network slice, then the admission control is performed according to the network slice identifier broadcasted by the base station and the corresponding admission control type, and the admission control parameter corresponding to the admission control type; or

对应于步骤200中的方式三，接纳控制类型为基站广播的接纳控制类型的一个或多个。Corresponding to mode 3 in step 200, the admission control type is one or more of the admission control types broadcast by the base station.

终端的非接入层或应用层将终端发起的业务请求映射为收到的信息中的接纳控制类型，并根据接纳控制类型对应的接纳控制参数执行接纳控制；如果收到的信息中包括有基站广播的接纳控制类型映射规则，那么，应使用接纳控制类型映射规则来覆盖正在使用的接纳控制类型映射规则；或者，The non-access stratum or the application layer of the terminal maps the service request initiated by the terminal to the admission control type in the received information, and performs admission control according to the admission control parameter corresponding to the admission control type; if the received information includes the base station The admission control type mapping rule of the broadcast, then the admission control type mapping rule should be used to override the admission control type mapping rule being used; or

终端的非接入层或应用层将终端发起的业务请求映射为收到的信息中的接纳控制类型，并根据接纳控制类型对应的接纳控制参数执行接纳控制；或者，The non-access stratum or the application layer of the terminal maps the service request initiated by the terminal to the admission control type in the received information, and performs admission control according to the admission control parameter corresponding to the admission control type; or

通过本公开提供的实现网络切片接纳控制的方法，实现了对基于网络切片的接纳控制，使得当某个网络切片的网络配置发生变化时，提供了对归属不同网络切片的不同业务请求的用户如何采用相应的接纳控制的处理方式。Through the method for implementing network slice admission control provided by the present disclosure, the network slice-based admission control is implemented, so that when a network configuration of a network slice changes, how to provide users for different service requests belonging to different network slices The corresponding admission control method is adopted.

本公开还提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行本公开任一项的实现网络切片接纳控制的方法。The present disclosure also provides a computer readable storage medium storing computer executable instructions for performing the method of implementing network slice admission control of any of the present disclosure.

下面结合几个实施例对本公开的网络切片处理方法进行详细描述。The network slice processing method of the present disclosure will be described in detail below in conjunction with several embodiments.

第一实施例，以步骤200中的方式一为例，且假设网络配置发生变化为网络切片发生拥塞，包括以下步骤：The first embodiment takes the mode 1 in step 200 as an example, and assumes that the network configuration changes to congestion of the network slice, including the following steps:

步骤11：基站广播网络切片标识及对应的接纳控制类型，以及接纳控制类型对应的接纳控制参数。其中，Step 11: The base station broadcasts the network slice identifier and the corresponding admission control type, and the admission control parameter corresponding to the admission control type. among them,

比如：网络切片标识标识可以为Slice ID或NSSAI，S-NSSAI。For example, the network slice identifier can be Slice ID or NSSAI, S-NSSAI.

对应的接纳控制类型可以为一种或多种。比如为类型0(category 0)，category1。The corresponding admission control type may be one or more. For example, type 0 (category 0), category1.

每一种接纳控制类型的接纳控制参数可以不一样。比如：可以为禁止接入或配置禁止因子(baring factor)，以及禁止时间(baring time)。The admission control parameters for each type of admission control may be different. For example, it can be prohibited to access or configure the baring factor and the baring time.

可选地，基站也可以同时广播没有网络切片属性的接纳控制类型及其对应的接纳控制参数。这样，本公开方法也适用于没有网络切片的终端的业务接纳控制。Optionally, the base station may simultaneously broadcast the admission control type without the network slice attribute and its corresponding admission control parameter. Thus, the disclosed method is also applicable to traffic admission control for terminals without network slicing.

第一实施例中基站广播的信息的一个示例可以如表1所示：An example of the information broadcast by the base station in the first embodiment can be as shown in Table 1:

表1Table 1

步骤12：当某网络切片发生拥塞时，基站修改发生拥塞的网络切片标识对应的接纳控制类型，及该接纳控制类型对应的接纳控制参数。Step 12: When a network slice is congested, the base station modifies the admission control type corresponding to the network slice identifier in which the congestion occurs, and the admission control parameter corresponding to the admission control type.

当网络切片发生拥塞时，核心网通过地面侧接口向基站报告某网络切片拥塞。发生拥塞的网络切片的信息和拥塞信息可以通过NG-C接口或S1接口发送给基站。该消息可以重用现有的消息或者新建立消息。When the network slice is congested, the core network reports a network slice congestion to the base station through the ground side interface. The information of the network slice in which congestion occurs and the congestion information can be sent to the base station through the NG-C interface or the S1 interface. This message can reuse existing or newly created messages.

本步骤中，基站根据拥塞信息修改对应网络切片的接纳控制参数。基站可以通过寻呼消息通知终端对应的网络切片的接纳控制信息已经改变。In this step, the base station modifies the admission control parameter of the corresponding network slice according to the congestion information. The base station may notify the terminal that the admission control information of the network slice corresponding to the terminal has changed by using a paging message.

比如：假设网络切片1发生了拥塞，本实施例中，假设需要修改其对应的接纳控制类型A的接纳控制参数，或者接纳控制类型A和接纳控制类型B的接纳控制参数，则修改系统广播消息中网络切片1受影响的接纳控制类型A的接纳控制参数，或者接纳控制类型A和接纳控制类型B的接纳控制参数。或者，假设需要修改接纳控制类型，比如原先存在接纳控制类型A，可以修改为接纳控制类型C等。For example, if congestion occurs in the network slice 1, in this embodiment, it is assumed that the admission control parameter of the corresponding admission control type A needs to be modified, or the admission control parameters of the control type A and the admission control type B are accepted, and the system broadcast message is modified. The admission control parameter of the admission control type A of the affected network slice 1 or the admission control parameter of the admission control type A and the admission control type B. Or, it is assumed that the admission control type needs to be modified, for example, the admission control type A is originally present, and can be modified to accept the control type C and the like.

表2Table 2

或者，当网络切片发生拥塞时，核心网直接修改发生拥塞的网络切片的接纳控制类型对应的接纳控制参数，并通过NG-C接口或S1接口发送给基站。该消息可以重用现有的消息好哦这新建立消息。Alternatively, when the network slice is congested, the core network directly modifies the admission control parameter corresponding to the admission control type of the network slice in which the congestion occurs, and sends the admission control parameter to the base station through the NG-C interface or the S1 interface. This message can reuse existing messages. This new setup message.

步骤13：终端业务请求映射为接纳控制类型并执行接纳控制。Step 13: The terminal service request is mapped to the admission control type and the admission control is performed.

本实施例中，映射不考虑业务请求类型的网络切片属性，不同网络切片的相同业务均映射为相同的接纳控制类型。接纳控制类型为基站广播的接纳控制类型的一个或多个。In this embodiment, the mapping does not consider the network slice attribute of the service request type, and the same service of different network slices is mapped to the same admission control type. The admission control type is one or more of the admission control types broadcast by the base station.

终端的接入层获得步骤11或步骤12的信息后，将获得的信息传递给终端的非接入层；After obtaining the information of step 11 or step 12, the access layer of the terminal transmits the obtained information to the non-access stratum of the terminal;

终端的非接入层或应用层将终端发起的业务请求映射为获得的信息中的接纳控制类型，并根据接纳控制类型对应的接纳控制参数执行接纳控制；或者，终端的非接入层或应用层将终端发起的业务请求映射为获得的信息中的接纳控制类型，并将接纳控制类型提交给终端的接入层，终端的接入层根据映射后的接纳控制类型和基站广播的信息执行接纳控制。The non-access stratum or the application layer of the terminal maps the service request initiated by the terminal to the admission control type in the obtained information, and performs admission control according to the admission control parameter corresponding to the admission control type; or the non-access stratum or application of the terminal The layer maps the service request initiated by the terminal to the admission control type in the obtained information, and submits the admission control type to the access layer of the terminal, and the access layer of the terminal performs the admission according to the mapped admission control type and the information broadcast by the base station. control.

如图3所示，业务类型1映射为接纳控制类型2，业务类型2映射为接纳控制类型3。其中，映射关系与终端的业务归属地网络切片没有关联，相同业务在不同网络切片中仍然映射为相同的接纳控制类型。As shown in FIG. 3, service type 1 is mapped to admission control type 2, and service type 2 is mapped to admission control type 3. The mapping relationship is not associated with the network slice of the service home of the terminal, and the same service is still mapped to the same admission control type in different network slices.

终端应用层或非接入层获得业务请求归属的网络切片标识信息如S-NSSAI，根据上述映射关系将其业务类型映射为接纳请求类型值，终端应用层或非接入层将接纳控制类型传送到终端的接入层；The terminal application layer or the non-access stratum obtains the network slice identification information of the service request, such as S-NSSAI, and maps its service type to the admission request type value according to the foregoing mapping relationship, and the terminal application layer or the non-access layer transmits the admission control type. Access layer to the terminal;

终端的接入层获取系统广播消息中的接纳控制信息，并根据网络切片标识信息找到对应接纳控制类型执行接纳控制；或者，终端的接入层将广播消息中的接纳控制信息传递给终端应用层或非接入层，终端的应用层或非接入层根据所述信息进行接纳控制。The access layer of the terminal acquires the admission control information in the system broadcast message, and finds the corresponding admission control type execution admission control according to the network slice identification information; or the access layer of the terminal transmits the admission control information in the broadcast message to the terminal application layer. Or the non-access stratum, the application layer or the non-access stratum of the terminal performs admission control according to the information.

如果终端的业务请求没有明确的网络切片信息，或者只有NSSAI信息，或者网络切片信息不在基站广播的接纳控制中，那么，使用网络切片公共控制信息中的接纳控制参数进行接纳控制。If the service request of the terminal does not have explicit network slice information, or only NSSAI information, or the network slice information is not in the admission control of the base station broadcast, the admission control parameter in the network slice common control information is used for admission control.

第二实施例以方式二为例，且假设网络配置发生变化为网络切片发生拥塞，包括以下步骤：The second embodiment takes the second mode as an example, and assumes that the network configuration changes to congestion of the network slice, including the following steps:

步骤21：基站广播统一的接纳控制类型，以及接纳控制类型对应的接纳控制参数。其中，Step 21: The base station broadcasts a unified admission control type and admission control parameters corresponding to the admission control type. among them,

基站广播的统一的接纳控制类型，以及接纳控制类型对应的接纳控制参数假设如表3所示：The unified admission control type of the base station broadcast and the admission control parameter assumption corresponding to the admission control type are as shown in Table 3:

接纳控制类型0Acceptance control type 0 接纳控制参数Acceptance control parameters …...

…... 接纳控制类型NAdmission control type N 接纳控制参数Acceptance control parameters

表3table 3

步骤22：当某网络切片发生拥塞时，基站在广播统一的接纳控制类型，以及接纳控制类型对应的接纳控制参数之外，还广播发生拥塞的网络切片标识及对应的接纳控制类型，以及接纳控制类型对应的接纳控制参数。Step 22: When a network slice is congested, the base station broadcasts the unified admission control type and the admission control parameter corresponding to the admission control type, and also broadcasts the congested network slice identifier and the corresponding admission control type, and the admission control. The admission control parameter corresponding to the type.

如表4所示，如果本实施例中网络切片X出现拥塞需要修改接纳控制参数，那么，基站还需要广播图4中的该络切片X对应的接纳控制类型。As shown in Table 4, if the congestion of the network slice X in this embodiment requires modification of the admission control parameter, the base station also needs to broadcast the admission control type corresponding to the network slice X in FIG.

表4Table 4

可选地，网络切片X的接纳控制类型及其对应的接纳控制参数可以由核心网元配置给基站；或者，核心网云通过过载指示提示基站网络切片X发生拥塞，再由基站为该网络切片X的接纳控制类型配置相关的接纳控制参数。Optionally, the admission control type of the network slice X and its corresponding admission control parameter may be configured by the core network element to the base station; or the core network cloud prompts the base station network slice X to be congested by the overload indication, and then the base station slices the network. The admission control type of X configures the associated admission control parameters.

其中，可以通过NG-C接口或S1接口发送给基站。该消息可以重用现有的消息或者新建立消息。The eNB can be sent to the base station through the NG-C interface or the S1 interface. This message can reuse existing or newly created messages.

步骤23：终端业务请求映射为接纳控制类型并执行接纳控制。Step 23: The terminal service request is mapped to the admission control type and the admission control is performed.

本实施例中，映射需要考虑业务请求类型的网络切片属性，不同网络切片的相同业务可以映射为相同的接纳控制类型，也可以映射为不相同的接纳控制类型。接纳控制类型为基站广播的接纳控制类型的一个或多个。In this embodiment, the mapping needs to consider the network slice attribute of the service request type. The same service of different network slices may be mapped to the same admission control type, or may be mapped to different admission control types. The admission control type is one or more of the admission control types broadcast by the base station.

如图4所示，业务类型1在网络切片1中映射为接纳控制类型3，而在网络切片2中映射为接纳控制类型2。业务类型2在网络切片1中映射为接纳控制类型2，而在网络切片2中映射为接纳控制类型4。As shown in FIG. 4, service type 1 is mapped to admission control type 3 in network slice 1 and to admission control type 2 in network slice 2. Traffic type 2 is mapped to admission control type 2 in network slice 1 and to admission control type 4 in network slice 2.

终端应用层或非接入层获得业务请求归属的网络切片标识信息如S-NSSAI，根据上述映射关系将其业务类型映射为接纳控制类型值，终端应用层或非接入层将这接纳控制类型传送到终端的接入层；The terminal application layer or the non-access stratum obtains the network slice identification information of the service request, such as S-NSSAI, and maps its service type to the admission control type value according to the foregoing mapping relationship, and the terminal application layer or the non-access layer adopts the admission control type. An access layer transmitted to the terminal;

终端的接入层获取系统广播消息中的接纳控制信息，直接根据接纳控制类型执行接纳控制；或者，终端的接入层将广播消息中的接纳控制类型及接纳控制类型传递给终端应用层或非接入层，终端的应用层或非接入层根据所述信息进行接纳控制。The access layer of the terminal acquires the admission control information in the system broadcast message, and directly performs the admission control according to the admission control type; or the access layer of the terminal transmits the admission control type and the admission control type in the broadcast message to the terminal application layer or the non- The access layer, the application layer or the non-access stratum of the terminal performs admission control according to the information.

如果步骤22中，基站广播了基于网络切片的接纳控制类型及其接纳控制信息，那么，终端的接入层将收到的该广播信息发送给终端应用层或非接入层，其中携带有网络切片标识信息和接纳控制类型信息；终端应用层或非接入层根据业务的网络切片信息找到对应的接纳控制信息并执行接纳控制；或者，终端的应用层或非接入层将终端业务的网络切片信息发送给终端的接入层。终端的接入层获得对应的接纳控制参数并执行接纳控制。If the base station broadcasts the network slice-based admission control type and its admission control information in step 22, the access layer of the terminal sends the received broadcast information to the terminal application layer or the non-access layer, where the network is carried. The slice identification information and the admission control type information; the terminal application layer or the non-access layer finds the corresponding admission control information according to the network slice information of the service and performs the admission control; or the application layer of the terminal or the non-access layer layer the network of the terminal service The slice information is sent to the access layer of the terminal. The access layer of the terminal obtains the corresponding admission control parameters and performs admission control.

第三实施例以方式三为例，且假设网络配置发生变化为网络切片发生拥塞，包括以下步骤：The third embodiment takes the third mode as an example, and assumes that the network configuration changes to congestion of the network slice, including the following steps:

步骤31：基站广播统一的接纳控制类型，以及接纳控制类型对应的接纳控制参数。其中，Step 31: The base station broadcasts a unified admission control type and admission control parameters corresponding to the admission control type. among them,

步骤32：当某网络切片发生拥塞时，基站在广播统一的接纳控制类型，以及接纳控制类型对应的接纳控制参数之外，基站还广播接纳控制类型映射规则。其中，接纳控制类型映射规则用于覆盖终端侧非接入层或应用层用于推导接纳控制类型的规则。Step 32: When a certain network slice is congested, the base station broadcasts a unified admission control type and an admission control parameter corresponding to the admission control type, and the base station also broadcasts an admission control type mapping rule. The admission control type mapping rule is used to cover a rule of the terminal side non-access stratum or the application layer for deriving the admission control type.

可选地，上述接纳控制类型映射规则可以由核心网元配置并通过地面侧接口发送给基站；或者，由核心网元通过地面侧接口发送拥塞指示给基站，基站配置接纳控制类型映射映射规则。Optionally, the foregoing admission control type mapping rule may be configured by the core network element and sent to the base station through the ground side interface; or the core network element sends a congestion indication to the base station through the ground side interface, and the base station configures the admission control type mapping mapping rule.

比如：根据原先的接纳控制类型映射规则，如图4所示，业务类型1在网络切片1中映射为接纳控制类型2，而业务类型2在网络切片1中映射为接纳控制类型2。假设，本实施例中基站广播更新的接纳控制类型映射规则显示，如图5所示，业务类型1在网络切片1中映射为接纳控制类型3，而业务类型2在网络切片1中映射为接纳控制类型4。For example, according to the original admission control type mapping rule, as shown in FIG. 4, the service type 1 is mapped to the admission control type 2 in the network slice 1, and the service type 2 is mapped to the admission control type 2 in the network slice 1. It is assumed that the admission control type mapping rule of the base station broadcast update in this embodiment shows that, as shown in FIG. 5, the service type 1 is mapped to the admission control type 3 in the network slice 1, and the service type 2 is mapped to the admission in the network slice 1. Control type 4.

步骤33：终端业务请求映射为接纳控制类型并执行接纳控制。Step 33: The terminal service request is mapped to the admission control type and the admission control is performed.

本实施例中，接纳控制类型为基站广播的接纳控制类型的一个或多个。In this embodiment, the admission control type is one or more of the admission control types broadcast by the base station.

终端的接入层获得步骤31或32的信息后，将广播信息传递给终端的非接入层；After obtaining the information of step 31 or 32, the access layer of the terminal transmits the broadcast information to the non-access stratum of the terminal;

终端的非接入层或应用层将终端发起的业务请求映射为接纳控制类型，并根据接纳控制类型对应的接纳控制参数执行接纳控制。如果步骤32中基站广播了新的接纳控制类型映射规则，则应使用新的接纳控制类型映射规则来覆盖正在使用的接纳控制类型映射规则。The non-access stratum or application layer of the terminal maps the service request initiated by the terminal to the admission control type, and performs admission control according to the admission control parameter corresponding to the admission control type. If the base station broadcasts a new admission control type mapping rule in step 32, the new admission control type mapping rule should be used to override the admission control type mapping rule being used.

比如，假设根据原先的接纳控制类型映射规则，业务类型1在网络切片1中映射为接纳控制类型2，则在新的接纳控制类型映射规则中，业务类型1在网络切片1中映射为接纳控制类型3。则终端将根据接纳控制类型3对应的接纳控制参数实行接纳控制。For example, if traffic type 1 is mapped to admission control type 2 in network slice 1 according to the original admission control type mapping rule, service type 1 is mapped to admission control in network slice 1 in the new admission control type mapping rule. Type 3. Then the terminal will perform admission control according to the admission control parameter corresponding to the admission control type 3.

其他接纳控制与第一实施例和第二实施例的过程相同，这里不再赘述。Other admission control processes are the same as those of the first embodiment and the second embodiment, and are not described herein again.

第四实施例以方式四为例，且假设网络配置发生变化为网络切片发生拥塞，包括以下步骤：The fourth embodiment takes the mode 4 as an example, and assumes that the network configuration changes to cause network slice congestion, including the following steps:

步骤41：基站广播统一的接纳控制类型，以及接纳控制类型对应的接纳控制参数。其中，Step 41: The base station broadcasts a unified admission control type and an admission control parameter corresponding to the admission control type. among them,

网络切片分别对应不同的接纳控制类型。The network slices correspond to different admission control types.

所述映射关系可以如图6所示，比如：网络切片1只能对应接纳控制类型1和接纳控制类型2。网络切片2是无法使用接纳控制类型1和接纳控制类型2的。The mapping relationship may be as shown in FIG. 6. For example, the network slice 1 can only correspond to the admission control type 1 and the admission control type 2. Network slice 2 is unable to use admission control type 1 and admission control type 2.

步骤42：当某网络切片发生拥塞时，基站修改发生拥塞的网络切片标识对应的接纳控制类型，以及接纳控制类型对应的接纳控制参数。Step 42: When congestion occurs in a network slice, the base station modifies the admission control type corresponding to the network slice identifier in which the congestion occurs, and the admission control parameter corresponding to the admission control type.

本实施例中，假设网络切片2发生拥塞并需要新的接纳控制，基站可以更新并广播网络切片2对应的接纳控制类型3和接纳控制类型4中的接纳控制参数。如表5所示。In this embodiment, assuming that the network slice 2 is congested and requires new admission control, the base station can update and broadcast the admission control type 3 corresponding to the network slice 2 and the admission control parameter in the admission control type 4. As shown in Table 5.
