背景技术Background technique

为了保持第三代移动通信***在通信领域的竞争力，为用户提供速率更快、时延更低、更加个性化的移动通信服务，同时，降低运营商的运营成本，3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)标准工作组正致力于演进分组***(Evolved Packet System，简称EPS)的研究。In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, it provides users with faster, less delayed and more personalized mobile communication services, and at the same time reduces operators' operating costs. 3GPP (3rd Generation Partnership Project) The 3rd Generation Partnership Project) Standards Working Group is working on the Evolved Packet System (EPS) research.

图1为相关技术中EPS的结构图。在EPC分组核心网中，包含了HSS(Home Subscriber Server，归属用户数据服务器)、MME(Mobility Management Entity，移动性管理实体)、S-GW(Serving Gateway，服务网关)、P-GW(PDN Gateway，分组数据网络网关)、SGSN(Serving GPRS Support Node，服务GPRS支持节点)和PCRF(Policy and Charging Enforcement Function，策略与计费规则功能实体)，其中：Fig. 1 is a structural diagram of an EPS in the related art. The EPC packet core network includes an HSS (Home Subscriber Server), an MME (Mobility Management Entity), an S-GW (Serving Gateway), and a P-GW (PDN Gateway). , Packet Data Network Gateway, SGSN (Serving GPRS Support Node), and PCRF (Policy and Charging Enforcement Function), where:

HSS(Home Subscriber Server)：归属用户数据服务器，是用户签约数据的永久存放地点，位于用户签约的归属网；HSS (Home Subscriber Server): a home subscriber data server, which is a permanent storage location for user subscription data, and is located in the home network to which the user subscribes;

MME(Mobility Management Entity)：移动性管理实体，是用户签约数据在当前网络的存放地点，负责终端到网络的NAS(Non-Access Stratum,非接入层)信令管理、用户空闲模式下的跟踪和寻呼管理功能和承载管理；MME (Mobility Management Entity): The mobility management entity is the location where the user subscription data is stored in the current network. It is responsible for terminal-to-network NAS (Non-Access Stratum) signaling management and user idle mode tracking. And paging management functions and bearer management;

S-GW(Serving Gateway)：服务网关，是核心网到无线***的网关，负责终端到核心网的用户面承载、终端空闲模式下的数据缓存、网络侧发起业务请求的功能、合法窃听和分组数据路由和转发功能；S-GW (Serving Gateway): A gateway that is a core network to a wireless system. It is responsible for user plane bearer from the terminal to the core network, data buffering in the idle mode of the terminal, function of initiating service requests on the network side, legal eavesdropping and grouping. Data routing and forwarding functions;

P-GW(PDN Gateway)：分组数据网络网关，是演进的分组域***(EPS)和该***外部网络的网关，负责终端的IP地址分配、计费功能、分组包过滤、策略应用等功能。P-GW (PDN Gateway): a packet data network gateway, which is an evolved packet domain system (EPS) and a gateway of the external network of the system. It is responsible for IP address allocation, charging function, and packetization of the terminal. Filter, strategy application and other functions.

SGSN(Serving GPRS Support Node)：服务GPRS支持节点，是GERAN和UTRAN用户接入EPC网络的业务支持点，功能上与MME类似，负责用户的位置更新、寻呼管理和承载管理等功能。Served GPRS Support Node (SGSN) is a service support point for GERAN and UTRAN users to access the EPC network.

PCRF(Policy and Charging Enforcement Function)：策略与计费规则功能实体，负责向PCEF提供策略控制与计费规则。Policy and Charging Enforcement Function (PCRF): The policy and charging rule function entity is responsible for providing policy control and charging rules to the PCEF.

在某些应急情况下，基站可能与核心网断开连接或者保持有限的连接(即控制面的消息传递可以保证，但是用户面数据的可能无法保证)，此时网络中部分特殊用户，例如跟国家公共安全相关的人员，需要快速建立一个应急通信的网络，以保证在特殊情况下提供特殊的业务。In some emergency situations, the base station may be disconnected from the core network or maintain a limited connection (ie, the control plane's message delivery can be guaranteed, but the user plane data may not be guaranteed). At this time, some special users in the network, for example, National public safety-related personnel need to quickly establish a network of emergency communications to ensure that special services are provided under special circumstances.

应急通信的网络，又称为孤立网络，采用的网络架构与相关的架构并无不同。但是考虑应急通信网络的特殊性，可能会考虑多个逻辑功能实体集成在一个或者几个实体网元中。此外由于临时建立的应急通信网络的能力比较有限，因此能够服务的对象、提供的业务都具有一定的局限性。由于公共安全用户的级别是比较高的，因此要求应急通信网络需要能够为公共安全用户提供服务。但是考虑到不同的应用场景，在应急通信网络能力足够的时候，也可以考虑更多的业务，如紧急业务。因此如何对应急通信网络的接入用户进行控制是亟待解决的问题。The network for emergency communication, also known as an isolated network, uses a network architecture that is no different from the related architecture. However, considering the particularity of the emergency communication network, multiple logical functional entities may be considered to be integrated into one or several physical network elements. In addition, due to the limited ability of the temporarily established emergency communication network, the objects that can be served and the services provided have certain limitations. Since the level of public safety users is relatively high, it is required that the emergency communication network needs to be able to provide services for public safety users. However, considering different application scenarios, when the capacity of the emergency communication network is sufficient, more services, such as emergency services, can also be considered. Therefore, how to control the access users of the emergency communication network is an urgent problem to be solved.

由上可以看出，通过与应急通信网络中可用的移动管理实体进行通信，可以简单快捷地获取到应急通信网络的网络状态信息，对该应急通信网络的业务管理提供了依据。It can be seen from the above that by communicating with the mobile management entity available in the emergency communication network, the network status information of the emergency communication network can be obtained simply and quickly, and the basis for the service management of the emergency communication network is provided.

其中，在基站根据所述应急通信网络的网络能力信息和/或网络负荷信息，控制用户是否允许接入所述应急通信网络时，还可以根据所述基站的自身负荷信息中的至少一个，控制用户是否允许接入所述应急通信网络。The base station controls, according to the network capability information and/or the network load information of the emergency communication network, whether the user is allowed to access the emergency communication network, and may further control according to at least one of the self-load information of the base station. Whether the user is allowed to access the emergency communication network.

在对应急接入网络的业务进行管理时，根据基站的自身负荷进行管理，可以有效的保证业务的成功接入。When the service of the emergency access network is managed, the management is based on the load of the base station, which can effectively ensure the successful access of the service.

通过上述三种方式，对相关的通信协议修改少，通用性高，有利用后续使用。Through the above three methods, the related communication protocol is less modified, the versatility is high, and the subsequent use is utilized.

由于应急通信网络的网络状态是在随着业务的处理过程在发生变化的，为了实现对应急通信网络的精确管理，所述基站在检测到应急通信网络的网络能力信息和/或网络负荷信息和/或接入控制操作信息发生变化后，根据发生变化后的应急通信网络的网络能力信息和/或网络负荷信息和/或接入控制操作信息，控制用户是否允许接入所述应急通信网络。Since the network state of the emergency communication network is changing along with the processing of the service, in order to achieve accurate management of the emergency communication network, the base station detects network capability information and/or network load information of the emergency communication network and After the change of the access control operation information, the user is allowed to access the emergency communication network according to the network capability information and/or the network load information and/or the access control operation information of the changed emergency communication network.

由上可以看出，在上述时机获取网络状态信息，信息准确。It can be seen from the above that the network status information is obtained at the above timing, and the information is accurate.

下面对终端侧的方法流程进行说明：The following describes the method flow on the terminal side:

根据广播指示中信息，得到所述应急通信网络的接入控制信息。Obtaining access control information of the emergency communication network according to the information in the broadcast indication.

终端通过广播方式来获取接入控制信息，实现简单方便。The terminal obtains access control information through broadcast, which is simple and convenient.

终端可以根据得到的基站的信息确定是否发起连接建立请求，实现对应急通信网络的接入管理，达到管理应急通信网络的目的。The terminal may determine whether to initiate a connection establishment request according to the obtained information of the base station, implement access management of the emergency communication network, and achieve the purpose of managing the emergency communication network.

可选的，所述方法还包括：Optionally, the method further includes:

下面以两个应用实例对上述方法做进一步说明：The above method is further explained by two application examples:

如下实施例可以应用于EUTRAN(Evolved Universal Terrestrial Radio Access Network，演进的通用陆基无线接入网)，以及后续衍生的其他网络。在EUTRAN网络中，移动管理实体指的就是MME，而基站指的是eNode。如果应用于后续衍生了其他的类似网络，则移动管理实体指的是完成移动管理功能，实现接入控制功能的与EUTRAN网络中MME类似的功能单元，而基站是实现了终端接入的无线侧网元。The following embodiment can be applied to EUTRAN (Evolved Universal Terrestrial Radio) Access Network, an evolved universal land-based radio access network), and other networks that are subsequently derived. In the EUTRAN network, the mobility management entity refers to the MME and the base station refers to the eNode. If applied to the subsequent derivation of other similar networks, the mobility management entity refers to a functional unit that implements the mobility management function, implements the access control function similar to the MME in the EUTRAN network, and the base station implements the radio side of the terminal access. Network element.

图4为本发明实施例提供的应急通信网络建立过程中网络设置接入控制的流程图。该实施方式可以用于当网络检测到骨干网已经断开后，根据管理***配置来检测可用的应急通信网络，检测到应急通信网络后，会建立应急通信网络。在应急通信网络的建立过程中，基站和核心网交互，确定当前允许接入用户和业务。也可以在检测到与骨干网之间的连接不稳定，只能提供有限的信令连接时，重新配置网络，以形成应急通信网络。FIG. 4 is a flowchart of network setting access control in an emergency communication network establishment process according to an embodiment of the present invention. The embodiment may be used to detect an available emergency communication network according to the management system configuration after the network detects that the backbone network has been disconnected, and establish an emergency communication network after detecting the emergency communication network. During the establishment of the emergency communication network, the base station interacts with the core network to determine the current allowed access to users and services. It is also possible to reconfigure the network to form an emergency communication network when it is detected that the connection with the backbone network is unstable and only a limited signaling connection is provided.

考虑到网络突然中断的初期，可能会有大量公共安全终端需要接入网络，因此在本流程中建议只允许公共安全的终端接入。如果允许其他终端的紧急业务接入，移动管理单元通知基站的信息设置，以及基站广播信息的设置与图5类似。Considering the initial interruption of the network, there may be a large number of public safety terminals that need to access the network. Therefore, it is recommended in this process that only public safety terminals are allowed to access. If emergency service access of other terminals is allowed, the mobility management unit notifies the base station of the information setting, and the setting of the base station broadcast information is similar to that of FIG.

步骤400，网络或者基站检测机制检测到基站与原来骨干网的连接断开，或者仅仅能够提供有限的连接，需要形成应急通信网络。Step 400: The network or base station detection mechanism detects that the connection between the base station and the original backbone network is disconnected, or only provides limited connection, and needs to form an emergency communication network.

步骤401，基站的管理***完成基站配置后，检测到应急通信网络中可用的移动管理实体，向其发送S1建立请求。Step 401: After completing the configuration of the base station, the management system of the base station detects the mobility management entity available in the emergency communication network, and sends an S1 establishment request thereto.

步骤402，移动管理实体向基站返回的S1建立响应，其中携带应急通信网络能够提供的业务类型，和/或移动管理实体的容量信息和/或接入控制操作信息。Step 402: The mobility management entity establishes a response to the S1 returned by the base station, where the type of service that the emergency communication network can provide, and/or the capacity information of the mobility management entity and/or the access control operation information.

由于应急通信网络主要是为了公共安全用户服务，因此在提供服务类型的时候可以通过几种方式实现：明确的指示网络能够提供的业务类型，例如只为公共安全用户服务、为公共安全用户和紧急业务用户服务等具体的类型；不携带任何类型的时候，认为只为公共安全用户服务，当可以提供其他业务类型的时候，具体指明能够提供业务类型的种类，例如紧急业务等。Since the emergency communication network is mainly for public safety user services, it can be implemented in several ways when providing the service type: clearly indicating the types of services that the network can provide, such as serving only public safety users, public safety users, and emergency. Specific types such as service user services; when not carrying any type, it is considered to be only for public security users. When other types of services can be provided, specify the types of services that can be provided, such as emergency services.

此外移动管理实体的容量信息也可以隐式的表明当前网络所能接受的服务类型，例如通过管理***设定一定的阈值：当达到某一容量门限的时候，只为公共安全用户服务；当达到另一容量门限的时候，为公共安全用户和紧急业务用户服务。In addition, the capacity information of the mobile management entity can also implicitly indicate the service that the current network can accept. The service type, for example, sets a certain threshold through the management system: when a certain capacity threshold is reached, only for public security users; when another capacity threshold is reached, for public security users and emergency service users.

对于公共安全使用特定PLMN接入的情况，在只允许公共安全用户接入的时候，就只包含公共安全的PLMN。允许公共安全用户和紧急业务用户接入的时候，可以包含公共安全专用的PLMN和移动管理实体能够支持的PLMN。In the case of public security using a specific PLMN access, only public safety PLMNs are included when only public safety users are allowed to access. When public safety users and emergency service users are allowed to access, they may include PLMNs that are public security-specific and PLMNs that the mobility management entity can support.

移动管理单元可以通过接入控制操作信息指示基站需要接入控制的具体操作，例如可以通过如下方式实现：接入控制的操作是只允许公共安全用户接入，或者同时为公共安全用户和紧急业务用户服务等具体的类型，或者同时为公共安全用户和紧急业务用户服务和普通用户的被叫业务服务，或者同时为公共安全用户和紧急业务用户服务和普通用户的信令接入等运营商实际需要的操作方式。The mobility management unit may indicate, by using the access control operation information, a specific operation that the base station needs to access the control, for example, by performing the following operations: the operation of the access control is to allow only public security users to access, or both public security users and emergency services. Specific types such as user services, or services for public safety users and emergency service users and called services for ordinary users, or operators for public security users and emergency service users and signaling access for ordinary users. The mode of operation required.

步骤403，基站根据步骤402中的指示信息和或自身的负荷信息，决定如何通过广播指示特定的用户接入。例如当步骤402中的指示为为公共安全用户和紧急业务用户服务，但是由于基站自身的负荷原因，基站也可以完全按照步骤402的指示允许公共安全用户和紧急业务用户接入，也可以根据自身的负荷只允许公共安全用户接入Step 403: The base station determines, according to the indication information in step 402 and the load information of itself, how to indicate a specific user access by broadcasting. For example, when the indication in step 402 is to serve the public safety user and the emergency service user, but due to the load of the base station itself, the base station may also allow the public security user and the emergency service user to access according to the instruction of step 402, or may be based on itself. Load only allows public safety users to access

步骤404，基站确定接入控制的等级后，可以通过，但不限于如下方式实现接入控制：Step 404: After determining the level of the access control, the base station may implement access control by using, but not limited to, the following manner:

1.基站在广播消息中，通过一个单独的IE设置是否只允许公共安全用户接入。当设置为只允许公共安全用户接入时，不允许其他任何非公共安全用户发起任何接入。如果允许公共安全用户接入，还可以通过其他广播消息的信元进一步判断是否可以发起紧急业务或者高优先级用户业务等等。基站具体的设置可以通过如下方式：设置一个新的IE，只是为允许公共安全用户接入，同时将指示其他业务的广播标志位，例如紧急业务，设置为不允许，以及其他高优先级的指示位都设置为不允许。这样非公共安全用户由于无法读取新增的指示位，或者能够读取的情况下发现自己不是公共安全用户，而读取到的其他业务或者由于不允许，或者由于优先级设置不匹配就不会进行接入。1. In the broadcast message, the base station sets whether to allow only public safety users to access through a single IE setting. When set to allow only public safety users to access, no other non-public security users are allowed to initiate any access. If public safety users are allowed to access, it is also possible to further judge whether it is possible to initiate emergency services or high-priority user services and the like through cells of other broadcast messages. The specific setting of the base station can be set as follows: a new IE is set, only to allow access by public safety users, and broadcast flag bits indicating other services, such as emergency services, are not allowed, and other high priority indications are set. Bits are set to not allowed. In this way, the non-public security user cannot read the newly added indicator bit, or can find that he is not a public security user, but the other services read are not allowed, or because the priority settings do not match. Will proceed Access.

2.基站利用相关广播消息中的IE在指示。当只允许公共安全用户接入时，将紧急业务允许标识设为禁止。利用access control(接入控制)来实现只允许公共安全用户接入。例如为公共安全用户设置新的access control取值，例如AC＝＝16(即相关技术没有设置的取值)，公共安全用户的终端需要将此置位表示自己是公共安全用户，同时基站设置允许这一取值的用户接入。或者要求公共安全用户将所有标识高优先级的AC都置位或者采用特殊的组合方式(这种方式需要运营商配置终端AC的时候有特殊的设定方式)，从而表示自己是个公共安全用户，同时基站设置允许都置位的用户接入。2. The base station uses the IE in the associated broadcast message to indicate. When only public safety users are allowed to access, the emergency service permission flag is set to prohibit. Access control is used to allow only public safety users to access. For example, a new access control value is set for the public safety user, for example, AC==16 (that is, the value is not set by the related art), and the terminal of the public safety user needs to set this to indicate that it is a public safety user, and the base station setting allows This value is accessed by the user. Or, the public security user is required to set all the high-priority ACs or use a special combination (this method requires the operator to configure the terminal AC when there is a special setting), thereby indicating that he is a public security user. At the same time, the base station sets up access for users that are allowed to be set.

3.对于公共安全可以使用特定PLMN接入的情况，如果基站仅仅允许公共安全用户接入，则只广播公共安全所特定的PLMN。如果基站还允许除公共安全用户之外的用户接入，还需要广播其他PLMN，而对于非公共安全用户可以进一步通过设置紧急业务允许标识来进一步区分用户，设置为只有紧急业务发起或者高优先级用户接入。3. For the case where public security can use a specific PLMN access, if the base station only allows access by public safety users, only public security specific PLMNs are broadcast. If the base station also allows users other than public safety users to access, it is also necessary to broadcast other PLMNs, and for non-public security users, the user can be further distinguished by setting an emergency service permission identifier, and set to only emergency service initiation or high priority. User access.

当通过这种方式设置为仅允许公共安全用户接入时，其他用户无法接入网络发起业务，但是如果其他用户发现周围没有可用的小区依然可以驻留在应急通信网络的小区中。此时的应急通信网络在负荷允许和/或网络能力允许的条件下，可以执行广播ETWS/PWS业务，对可能发生的危险进行预警，而这些非公共安全用户也可以通过监听广播的方式获取这些信息。When it is set in this way to allow only public safety users to access, other users cannot access the network to initiate services, but if other users find that there are no cells available around, they can still camp in the cell of the emergency communication network. At this time, the emergency communication network can perform broadcast ETWS/PWS services under the conditions of load permission and/or network capability, and provide early warning of possible dangers, and these non-public security users can also obtain these by monitoring broadcasts. information.

步骤405，终端根据广播信息与自己设置的接入控制标识位匹配，决定是否发起请求，接入网络。Step 405: The terminal matches the access control identifier bit set by itself according to the broadcast information, and determines whether to initiate a request and access the network.

终端在后续发起连接请求消息中会携带自己的类型(是否为公共安全用户)和/或自己的业务类型(紧急业务或者普通业务等)。基站可以根据这些信息和自己接入控制等级做匹配，在不匹配的情况下可以拒绝终端的连接请求。The terminal carries its own type (whether it is a public security user) and/or its own service type (emergency service or normal service, etc.) in the subsequent connection request message. The base station can match the information according to its own access control level, and can reject the connection request of the terminal if it does not match.

终端可以通过新增IE表明自己的类型(是否为公共安全用户)，也可以根据步骤404描述的方法通过相关IE的组合表明自己的类型。The terminal can indicate its own type (whether it is a public safety user) by adding an IE, or can indicate its type through a combination of related IEs according to the method described in step 404.

步骤406，执行接入网络的剩余流程。该流程在相关技术中已经描述，在本发明实施例中不再赘述。In step 406, the remaining process of accessing the network is performed. This process has been described in the related art. It will not be described in detail in the embodiment of the present invention.

由上可以看出，在应急通信网络建立过程中，对用户接入应急通信网络进行控制，一方面保证了应急通信网络的安全性，另一方面充分利用了应急通信网络的资源。It can be seen from the above that in the process of establishing the emergency communication network, the user is controlled to access the emergency communication network, on the one hand, the security of the emergency communication network is ensured, and on the other hand, the resources of the emergency communication network are fully utilized.

图5为本发明实施例提供的应急通信网络建立后变更网络接入控制的流程图。该实施方式可以用于应急通信网络建立后，网络的能力或者负荷信息发生了变化的时候，网络可以通知基站改变接入控制的策略，从而允许更多的用户接入，或者减少特定用户接入。如果网络能力发生了变化，能够提供的业务能力发生了变化，例如从有紧急业务的服务器到没有，就需要通知给基站，反之亦然。或者负荷发生了变化，比如接入用户过多，导致网络负荷较大，可以设置为只允许公共安全用户接入。或者接入用户数较少网络负荷较低，可以设置为允许公共安全用户以及紧急业务用户接入。FIG. 5 is a flowchart of changing network access control after an emergency communication network is established according to an embodiment of the present invention. The implementation may be used after the establishment of the emergency communication network, when the capability or load information of the network changes, the network may notify the base station to change the access control policy, thereby allowing more users to access, or reducing specific user access. . If the network capabilities change and the capabilities that can be provided change, such as from a server with emergency services to none, you need to notify the base station and vice versa. Or the load has changed, such as too many access users, resulting in a large network load, which can be set to allow only public safety users to access. Or the number of access users is small, the network load is low, and it can be set to allow public security users and emergency service users to access.

上述能力变化或者负荷信息的变化可以通过后台管理***进行配置，如果是完全后台控制，则不需要执行步骤501～502。The above capability change or the change of the load information may be configured by the background management system. If the background control is complete, the steps 501 to 502 need not be performed.

步骤500，应急通信网络的负荷发生了变化，或者应急通信网络本身的能力发生了变化。In step 500, the load of the emergency communication network changes, or the capabilities of the emergency communication network itself change.

步骤501，移动管理实体通知基站网络能力变化和或负荷变化。In step 501, the mobility management entity notifies the base station of network capability changes and or load changes.

通知方式可以是，但不局限于：通过配置更新消息通知基站，此时步骤501和步骤502都需要执行；通过过载控制开始或者过载控制结束来通知，此时不需要执行步骤502；通过新增消息来通知，根据需要可以将新消息设置为需要响应或者不需要响应的消息，如果需要则需要执行步骤502.The notification mode may be, but is not limited to, the base station is notified by the configuration update message, and both step 501 and step 502 need to be executed; the overload control start or the overload control end is notified, and step 502 is not required at this time; The message is notified that the new message can be set to a message that needs to respond or does not need to be responded according to needs, and if necessary, step 502 needs to be performed.

无论采用那种方式，都需要在该消息中包含携带应急通信网络能够提供的业务类型，和或移动管理实体的容量信息和/或接入控制操作信息。In either case, it is necessary to include in the message the type of service that the emergency communication network can provide, and the capacity information and/or access control operation information of the mobility management entity.

该消息中提供服务类型的时候可以通过几种方式实现：明确的指示网络能够提供的业务类型，例如只为公共安全用户服务、为公共安全用户和紧急业务用户服务等具体的类型；不携带任何类型的时候，认为只为公共安全用户服务，当可以提供其他业务类型的时候，具体指明能够提供业务类型的种类，例如紧急业务等。 The service type in the message can be implemented in several ways: explicitly indicating the type of service that the network can provide, such as serving only public safety users, public security users, and emergency service users. At the time of the type, it is considered to be only for public safety users. When other types of services can be provided, specify the types of services that can be provided, such as emergency services.

此外移动管理实体的容量信息也可以隐式的表明当前网络所能接受的服务类型，例如通过管理***设定一定的阈值：当达到某一容量门限的时候，只为公共安全用户服务；当达到另一容量门限的时候，为公共安全用户和紧急业务用户服务。In addition, the capacity information of the mobility management entity can also implicitly indicate the type of service that the current network can accept. For example, the management system sets a certain threshold: when a certain capacity threshold is reached, only the public security user is served; Another capacity threshold serves public safety users and emergency business users.

对于公共安全使用特定PLMN接入的情况，在只允许公共安全用户接入的时候，就只包含公共安全的PLMN。允许公共安全用户和紧急业务用户接入的时候，可以包含公共安全专用的PLMN和移动管理实体能够支持的PLMN。如果复用配置更新消息，则在该消息中通过发送不同的PLMN来实现上述功能。如果复用过载控制开始或者过载控制结束，或者增加新消息，则需要在这些消息中增加PLMN ID，并通过设置不同的取值来实现上述功能。In the case of public security using a specific PLMN access, only public safety PLMNs are included when only public safety users are allowed to access. When public safety users and emergency service users are allowed to access, they may include PLMNs that are public security-specific and PLMNs that the mobility management entity can support. If the configuration update message is multiplexed, the above functions are implemented in the message by transmitting different PLMNs. If the multiplex overload control starts or the overload control ends, or a new message is added, the PLMN ID needs to be added to these messages, and the above functions are implemented by setting different values.

步骤502，基站收到指示后返回响应消息。Step 502: After receiving the indication, the base station returns a response message.

步骤503，基站根据步骤501中的指示信息和或自身的负荷信息，决定如何通过广播指示特定的用户接入。例如当步骤501中的指示为为公共安全用户和紧急业务用户服务，但是由于基站自身的负荷原因，基站也可以完全按照步骤501的指示允许公共安全用户和紧急业务用户接入，也可以根据自身的负荷只允许公共安全用户接入。Step 503: The base station determines, according to the indication information in step 501 and the load information of itself, how to indicate a specific user access by broadcasting. For example, when the indication in step 501 is to serve public safety users and emergency service users, but due to the load of the base station itself, the base station may also allow public safety users and emergency service users to access according to the indication of step 501, or may be based on itself. The load only allows access by public safety users.

步骤504，基站确定接入控制的等级后，可以通过，但不限于如下方式实现接入控制：Step 504: After determining the level of the access control, the base station may implement access control by using, but not limited to, the following manner:

1.基站在广播消息中，通过一个单独的IE设置是否只允许公共安全用户接入。当设置为只允许公共安全用户接入时，不允许其他任何非公共安全用户发起任何接入。如果基站允许公共安全用户接入，还可以通过其他广播消息的信元进一步判断是否可以发起紧急业务或者高优先级用户业务等等。如果设置为紧急业务也可以接入，则这个IE需要表示为非仅限于公共安全用户接入。此时是否允许进行紧急业务，还需要进一步判断紧急业务允许标志位。紧急业务标志位的设置可以按照相关技术执行。基站具体的设置可以通过如下方式：设置一个新的IE，只是为允许公共安全用户接入，同时将指示其他业务的广播标志位，例如紧急业务，设置为不允许，以及其他高优先级的指示位都设置为不允许。这样非公共安全用户由于无法读取新增的指示位，或者能够读取的情况下发现自己不是公共安全用户，而读取到的其他业务或者由于不允许，或者由于优先级设置不匹配就不会进行接入。1. In the broadcast message, the base station sets whether to allow only public safety users to access through a single IE setting. When set to allow only public safety users to access, no other non-public security users are allowed to initiate any access. If the base station allows the public safety user to access, it can further judge whether the emergency service or the high priority user service or the like can be initiated by the cells of other broadcast messages. If it is set to be accessible for emergency services, this IE needs to be indicated as not restricted to public safety users. Whether emergency services are allowed at this time, further judgment of the emergency service permission flag is required. The setting of the emergency service flag can be performed in accordance with related technologies. The specific setting of the base station can be set as follows: a new IE is set, only to allow access by public safety users, and broadcast flag bits indicating other services, such as emergency services, are not allowed, and other high priority indications are set. Bits are set to not allowed. In this way, the non-public security user cannot read the newly added indicator bit, or can find that he is not a public security user, but the other services read are not allowed, or because the priority settings do not match. Will be accessed.

2.基站利用相关广播消息中的IE在指示。当只允许公共安全用户接入时，将紧急业务允许标识设为禁止。利用access control(接入控制)来实现只允许公共安全用户接入。例如为公共安全用户设置新的access control取值，例如AC＝＝16(即相关技术没有设置的取值)，公共安全用户的终端需要将此置位表示自己是公共安全用户，同时基站设置允许这一取值的用户接入。或者要求公共安全用户将所有标识高优先级的AC都置位或者采用特殊的组合方式(这种方式需要运营商配置终端AC的时候有特殊的设定方式)，从而表示自己是个公共安全用户，同时基站设置允许都置位的用户接入。如果设置为允许公共安全。而此时终端可以通过配置自己的AC标志位，跟网络进行匹配，从而决定自己是否是被允许接入网络的用户。2. The base station uses the IE in the associated broadcast message to indicate. When only public safety users are allowed to access, the emergency service permission flag is set to prohibit. Access control is used to allow only public safety users to access. For example, a new access control value is set for the public safety user, for example, AC==16 (that is, the value is not set by the related art), and the terminal of the public safety user needs to set this to indicate that it is a public safety user, and the base station setting allows This value is accessed by the user. Or, the public security user is required to set all the high-priority ACs or use a special combination (this method requires the operator to configure the terminal AC when there is a special setting), thereby indicating that he is a public security user. At the same time, the base station sets up access for users that are allowed to be set. If set to allow public safety. At this time, the terminal can configure its own AC flag to match the network to determine whether it is a user who is allowed to access the network.

当通过这种方式设置为仅允许公共安全用户接入时，虽然可以其他用户无法接入网络发起业务，但是如果其他用户发现周围没有可用的小区依然可以驻留在应急通信网络的小区中。此时的应急通信网络在负荷允许和/或网络能力允许的条件下，可以执行广播ETWS/PWS业务，对可能发生的危险进行预警，而这些非公共安全用户也可以通过监听广播的方式获取这些信息。 When it is set in this way to allow only public safety users to access, although other users cannot access the network to initiate services, if other users find that there are no cells available around, they can still camp in the cell of the emergency communication network. At this time, the emergency communication network can perform broadcast ETWS/PWS services under the conditions of load permission and/or network capability, and provide early warning of possible dangers, and these non-public security users can also obtain these by monitoring broadcasts. information.

步骤505，终端根据广播信息与自己设置的接入控制标识位匹配，决定是否发起请求，接入网络。Step 505: The terminal matches the access control identifier bit set by itself according to the broadcast information, and determines whether to initiate a request and access the network.

终端在后续发起连接请求消息中会携带自己的类型(是否为公共安全用户)和或自己的业务类型(紧急业务或者普通业务等)。基站可以根据这些信息和自己接入控制等级做匹配，在不匹配的情况下可以拒绝终端的连接请求。The terminal carries its own type (whether it is a public security user) or its own service type (emergency service or normal service, etc.) in the subsequent connection request message. The base station can match the information according to its own access control level, and can reject the connection request of the terminal if it does not match.
