Abstract

The embodiments provide an apparatus, a system and method for User Equipment (UE) identification of a shared network. An attachment request message transmitted via an eNB from a UE is received by a UE identification apparatus of a shared network, wherein the attachment request message includes information corresponding to a group to which the UE belongs; the UE identification apparatus of the shared network obtains an identifier of the group to which the UE belongs according to the information corresponding thereto, and the information corresponding to the group to which the UE belongs has a correspondence with the identifier thereof, thereby the UEs of different groups can be identified accurately and then the UEs of the groups can be processed and controlled differentiatedly, for example, the UEs of different groups are controlled according to the priorities of different groups; resource required by different groups is distributed for the UEs of different groups. The group to which the UE belongs is identified for different groups in the shared network, which is more advantageous to subsequently provision of services, such as differentiated QoS and safety policies etc., for the UEs of different groups.

Description

共享网络的用户设备识别装置、 ***及方法技术领域 User equipment identification device, system and method for shared network

本发明涉及通信技术，尤其涉及一种共享网络的用户设备识别装置、 ***及方法。背景技术 The present invention relates to communication technologies, and in particular, to a user equipment identification apparatus, system, and method for sharing a network. Background technique

随着网络共享能力的增强，用户设备（User Equipment, 简称： UE) 可以根据自身的特性被划分给不同的群组，其目的在于：以群组为粒度为属于一个群组的 UE分配不同的无线（Radio )接入资源、最大用户数、最大承载（Bearer) 、分组数据协议（Packet Data Protocol, 简称： PDP ) 资源、可用的业务（如短消息、定位业务）等，或者，根据不同群组实行资源控制与精确的策略。 With the enhancement of the network sharing capability, the user equipment (User Equipment, UE for short) can be allocated to different groups according to its own characteristics. The purpose is to allocate different UEs belonging to one group at the granularity of the group. Radio access resources, maximum number of users, maximum bearer, packet data protocol (PDP) resources, available services (such as short messages, positioning services), etc., or according to different groups The group implements resource control and precise strategies.

因此，识别 UE属于哪一个群组成为业界亟待解决的一个问题，现有技术中，对于通常采用公共陆地移动网络（Public Land Mobile Network, 简称： PLMN) ID来进行 UE的识别，如果直接利用 PLMN ID来识别，一种可能的情况是，群组是基于 UE所属的运营商来进行区分的，即一个群组中的 UE都属于同一个运营商，并且，不同的群组属于不同的运营商，这里不同的运营商可以包括：移动网络运营商（Mobile Network Operator, 简称： MNO )作为主运营商，网络与参与运营商（Participant MNO, 简称： PMNO ) ；其中，主运营商可以将网络与 PMNO共享，进一歩地， PMNO 可以为： MNO 运营商、移动虚拟网络运营商（Mobile Virtual Network Operator, 简称： MVNO ) 。对于这种场景， PMNO可能带有不同于主运营商的 PLMN ID, 主运营商可以通过 PLMN ID识别 PMNO的 UE并进一歩执行资源控制。而如果 PMNO与主运营商拥有同样的 PLMN ID, 或在其他场景例如网络中有 M2M群组用户或其他类型的政府、企业集团群组 UE, 且上述 UE的 PLMN ID与主运营商的 PLMN ID相同，在这种情况下主运营商无法识别上述 PMNO的 UE到底属于哪一个群组。更进一歩的，基于上述群组划分方式得到的不同群组，各自包含的 UE诉求具有明显差另 lj。即对于包含归属于主运营商的 UE，其群组关注点是:如何控制共享给 PMNO 的资源，该资源包括分配给 PMNO 的签约用户数，承载数以及吞吐量（分为无线侧与核心网侧），网络节点资源（包括共享网元数量，甚至每个网元的 CPU/内存等计算能力）。而归属于 PMNO的 UE, 其群组则更在意如何最大化的利用从主运营商租用的网络资源，即在不超出签约资源总量的基础上，尽量少受到各个网元 /小区的资源上限，将网络资源分配到需要的地方。显然，基于现有技术的 UE识别方法，是无法在上述场景中，识别 UE到底归属于哪一个群组的，进一歩地，也就不能够根据不同的群组划分对每个群组中的 UE进行区别化的处理和控制。 Therefore, identifying which group the UE belongs to is a problem that needs to be solved in the industry. In the prior art, the public land mobile network (Public Land Mobile Network, PLMN) ID is usually used for UE identification, if the PLMN is directly used. Identification by ID, a possible case is that the group is differentiated based on the operator to which the UE belongs, that is, the UEs in one group belong to the same operator, and different groups belong to different operators. The different operators here may include: Mobile Network Operator (MNO) as the main operator, network and participating operators (Participant MNO, PMNO for short); among them, the main operator can connect the network with PMNO sharing, further, PMNO can be: MNO operator, Mobile Virtual Network Operator (MVNO). For this scenario, the PMNO may have a PLMN ID different from the primary carrier, and the primary carrier may identify the UE of the PMNO through the PLMN ID and perform resource control further. If the PMNO has the same PLMN ID as the primary carrier, or in other scenarios such as the network, there are M2M group users or other types of government, enterprise group group UEs, and the PLMN ID of the UE and the PLMN ID of the primary carrier. In the same case, in this case, the primary carrier cannot identify which group the UE of the above PMNO belongs to. Further, the different groups obtained based on the group division method described above have significantly different UE claims. That is, for a UE that belongs to the primary carrier, the group focus is: how to control sharing The resources of the PMNO, including the number of subscribers allocated to the PMNO, the number of bearers and the throughput (divided into the wireless side and the core network side), the network node resources (including the number of shared network elements, and even the CPU/memory of each network element) Such as computing power). The UEs belonging to the PMNO, the group is more concerned about how to maximize the use of network resources leased from the main operator, that is, the resource limit of each network element/cell is minimized on the basis of not exceeding the total amount of the contracted resources. , allocate network resources to where they are needed. Obviously, the UE identification method based on the prior art cannot identify which group the UE belongs to in the above scenario, and further cannot be divided according to different groups for each group. The UE performs differentiated processing and control.

进一歩地，上述仅以主运营商和 PMNO 的群组区分方式进行举例说明，对于依据其他方式划分群组的方式，采用现有技术来识别 UE, 也会造成类似的技术问题，即对群组的处理和控制的准确性不高。发明内容 Further, the foregoing is only exemplified by the group division manner of the primary carrier and the PMNO. For the manner of dividing the group according to other methods, the prior art is used to identify the UE, which also causes similar technical problems, that is, the group The accuracy of the group's processing and control is not high.

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。 The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

用户设备（User Equipment, 简称： UE) 可以依据自身的特性被划分为不同的群组，例如，根据 UE所属运营商的不同，将属于同一运营商的 UE划分在相同的群组；根据 UE使用的业务类型划分，将使用相同业务的 UE划分在相同群组；根据 UE的优先级划分，将具有相同优先级的 UE 划分在相同群组等等，可见划分群组的方式多种多样，而相应的，依据不同的划分方式进行划分后，如何能够有效地识别一个 UE所属的群组，成为一个亟待解决的问题，因为只有在准确识别出一个 UE所属的群组的条件下，才能针对不同的群组实现差异化管理、处理和控制，进而实现最初划分群组的目的。本发明下述实施例提供一种共享网络的用户设备识别装置、 ***及方法，以解决识别 UE所属群组的问题。需要说明的是，下文实施例中对于群组划分的具体方式和执行划分群组、识别 UE所属群组的设备均作为示例进行说明，其并不限定本发明的保护范围。 The user equipment (User Equipment, UE for short) may be divided into different groups according to its own characteristics. For example, UEs belonging to the same operator are divided into the same group according to different operators of the UE; For the service type division, the UEs that use the same service are divided into the same group; according to the priority division of the UE, the UEs with the same priority are divided into the same group, etc., and the manners for grouping the groups are various, and Correspondingly, how to effectively identify a group to which a UE belongs is a problem that needs to be solved urgently after being divided according to different division manners, because only when a group to which a UE belongs is accurately identified can be different The group implements differentiated management, processing, and control to achieve the purpose of initially grouping. The following embodiments of the present invention provide a user equipment identification apparatus, system, and method for sharing a network to solve the problem of identifying a group to which a UE belongs. It should be noted that the specific manner for group division and the device for performing group division and identifying the group to which the UE belongs are described in the following embodiments as an example, which does not limit the scope of protection of the present invention.

图 1为本发明实施例提供的一种共享网络的用户设备识别装置的结构示意图，该装置具体可以为移动性管理网元（ Mobility Management Entity ，简称： MME) ，如无特别说明下文均已 MME作为示例进行说明，参照图 1，该装置，包括：接收模块 100、处理模块 101。 FIG. 1 is a schematic structural diagram of a user equipment identification device for sharing a network according to an embodiment of the present invention; For example, the device may be a Mobility Management Entity (MME). The MME is described as an example unless otherwise specified. Referring to FIG. 1, the device includes: a receiving module 100, a processing module. 101.

接收模块 100，用于接收用户设备（User Equipment, 简称： UE) 通过演进型基站 (evolved Node B，简称： eNB)发送的附着请求消息，所述附着请求消息包含所述 UE所属群组的对应信息； The receiving module 100 is configured to receive an attach request message sent by an evolved Node B (abbreviated as: eNB) by a user equipment (User Equipment, UE for short), where the attach request message includes a correspondence of a group to which the UE belongs. Information

具体的， UE所属群组的对应信息对应 UE所属群组标识，其具体形式可以为 UE的标识或 UE的接入点名称（ Access Point Name，简称： APN )，其中， UE的标识具体可以为 UE的国际移动用户识别码（International Mobile Subscriber Identity, 简称： IMSI ) 或 UE的全球唯一临时用户设备标识 ( Globally Unique Temporary UE Identity, 简称： GUTI ) 。进一歩地，可行的实现方式为：所述附着请求消息包含所述 UE的标识，所述 UE的标识包含所述 UE所属群组的对应信息；或者，所述附着请求消息包含所述 UE的 APN, 所述 UE的 APN包含所述 UE所属群组的对应信息。 Specifically, the corresponding information of the group to which the UE belongs is corresponding to the group identifier of the UE, and the specific form may be the identifier of the UE or the access point name of the UE (Access Point Name, APN for short), where the identifier of the UE may be specifically The International Mobile Subscriber Identity (IMSI) of the UE or the Globally Unique Temporary UE Identity (GUTI) of the UE. Further, the feasible implementation manner is as follows: the attach request message includes the identifier of the UE, and the identifier of the UE includes the corresponding information of the group to which the UE belongs; or the attach request message includes the UE The APN of the UE includes the corresponding information of the group to which the UE belongs.

具体的，对于 UE的 APN, 其作用通常为：通用分组无线服务技术 Specifically, for the APN of the UE, the role is usually: General Packet Radio Service Technology

( General Packet Radio Service,简称： GPRS) /通用移动通信*** (Universal Mobile Telecommunications System, 简称： UMTS)***定义的网络标识。一方面， GPRS/UMTS通过 APN标识出 GGSN; 另一方面， APN标识了通过该 GGSN所连接的外部 PDN (如 ISP网络、企业网等）或所关联的某种类型的业务（如 Internet接入、 WAP业务等）。在本实施例中，可以将 UE的 APN作为 UE所属群组的对应信息，以对应该 UE的 UE所属群组标识，例如，该 UE的 APN形式可以为； -cmwap.mnc010.mcc460.gprs。 (General Packet Radio Service, referred to as: GPRS) / Universal Mobile Telecommunications System (UMTS) system defined network identifier. On the one hand, GPRS/UMTS identifies the GGSN through the APN; on the other hand, the APN identifies the external PDN (such as an ISP network, an enterprise network, etc.) connected to the GGSN or a certain type of service (such as Internet access) , WAP services, etc.). In this embodiment, the APN of the UE may be used as the corresponding information of the group to which the UE belongs, to identify the group to which the UE of the UE belongs. For example, the APN form of the UE may be: -cmwap.mnc010.mcc460.gprs.

处理模块 101，用于根据所述 UE所属群组的对应信息，获取所述 UE 所属群组标识，所述 UE所属群组的对应信息与所述 UE所属群组标识具有对应关系。 The processing module 101 is configured to obtain, according to the corresponding information of the group to which the UE belongs, the group identifier to which the UE belongs, and the corresponding information of the group to which the UE belongs has a corresponding relationship with the group identifier to which the UE belongs.

需要说明的是，提供网络资源的主运营商会在 UE的标识中为该 UE 所属群组分配特定的一段识别码号段，作为所述 UE所属群组的对应信息，以对应该群组。或者，网络资源的主运营商会为一个群组分配特定的 APN, 并将该 APN分配给该群组中的 UE。 It should be noted that the primary carrier that provides the network resource allocates a specific segment of the identifier number to the group to which the UE belongs, as the corresponding information of the group to which the UE belongs, to correspond to the group. Alternatively, the primary operator of the network resource will assign a specific APN to a group and assign the APN to the UEs in the group.

进一歩地，对于获取 UE所属群组标识方式，根据 MME的功能划分为两种：当 MME具有解析功能时， MME可以解析 UE的标识或 UE的 APN获得 UE所属群组标识，根据自身存储的 UE的标识与群组标识的对应关系，得到 UE所属群组标识，或者根据自身存储的 UE的 APN与群组标识的对应关系，得到 UE所属群组标识；或者，对于没有解析功能的 MME, 可以通过向归属地签约用户服务器（Home Subscriber Service, 简称： HSS ) 发起鉴权流程，获取 UE所属群组标识。对于这两种获取方式会在下文中进行具体说明，此处不再赘述。 Further, for obtaining the group identification mode to which the UE belongs, according to the function division of the MME There are two types: When the MME has the parsing function, the MME may parse the identifier of the UE or the APN of the UE to obtain the group identifier of the UE, and obtain the group identifier to which the UE belongs according to the corresponding relationship between the identifier of the UE and the group identifier. Or, according to the corresponding relationship between the APN of the UE and the group identity, the group identifier of the UE is obtained; or, for the MME without the parsing function, the MME may be initiated by the Home Subscriber Service (HSS). The authentication process obtains the group identifier to which the UE belongs. The two acquisition methods will be specifically described below, and will not be described here.

For the interaction process of this scenario, a specific interaction example will be given below, which will not be described here.

需要说明的是，对于初始附着的过程（即，所述 UE的标识为所述 UE 的 IMSI ) 时， eNB的处理模块并不能无法进行 MME的选择，此时 eNB 会随机选择 MME进行初始附着，当该 MME无法为相应 UE提供服务时，会将该 UE所属群组标识发送给 eNB , 以使 eNB的处理模块根据 UE所属群组标识，为所述 UE选择所述 UE所属群组对应的移动性管理网元 MME。 It should be noted that, for the initial attach process (that is, the identifier of the UE is the IMSI of the UE), the processing module of the eNB cannot select the MME, and the eNB randomly selects the MME to perform initial attach. When the MME is unable to provide the service to the corresponding UE, the group identifier of the UE is sent to the eNB, so that the processing module of the eNB selects the mobile station corresponding to the group to which the UE belongs according to the group identifier of the UE. The management network element MME.

本实施例提供的共享网络的用户设备识别方法，所述 MME根据根据所述 UE所属群组的对应信息，确定所述 UE所属群组标识，从而准确地识别不同群组的 UE, 进而能够将针对群组的 UE实现差异化的处理和控制，例如，根据不同群组的优先级对不同群组的 UE进行控制；为不同群组的 UE分配不同群组所需的资源，对于共享网络，对于不同的群组，识别 UE所属的群组，更加利于后续对不同群组的 UE提供差异化服务质量 ( Quality of Service, 简称： QoS ) 、安全策略等服务。 In the user equipment identification method of the shared network provided by the embodiment, the MME determines the group identifier to which the UE belongs according to the corresponding information of the group to which the UE belongs, so as to accurately identify the UEs of different groups, and thus can Differentiated processing and control for groups of UEs For example, the UEs of different groups are controlled according to the priorities of different groups; the resources required by different groups are allocated to UEs of different groups, and for the shared network, for the different groups, the group to which the UE belongs is identified. The group is more conducive to providing services such as Quality of Service (QoS) and security policies for different groups of UEs.

进一歩地，对于初始化附着的场景，需要说明的是，当 UE进行初始化附着时，其 UE的标识为 UE的 IMSI, 而此时 UE所属群组的对应信息可以为 UE的 IMSI或 UE的 APN, 在此基础上，当共享网络的用户设备识别装置完成上述与 UE的 IMSI或 UE的 APN相关的歩骤之后，还可以具有如下功能： Further, for the scenario of initializing the attachment, it should be noted that when the UE performs initial attach, the identifier of the UE is the IMSI of the UE, and the corresponding information of the group to which the UE belongs may be the IMSI of the UE or the APN of the UE. On the basis of this, after the user equipment identifying device of the shared network completes the foregoing steps related to the IMSI of the UE or the APN of the UE, the following functions may also be performed:

在图 7的基础上，图 10为本发明实施例提供的另一种共享网络的用户设备识别方法流程示意图，参照图 10，歩骤 101之后，还包括： On the basis of FIG. 7, FIG. 10 is a schematic flowchart of another method for identifying a user equipment of a shared network according to an embodiment of the present invention. Referring to FIG. 10, after step 101, the method further includes:

歩骤 102、所述 MME根据所述 UE所属群组标识，为所述 UE选择网元设备。具体的， MME可以根据一些判断条件判断自身能够为 UE提供服务，例如 MME负载超过一定阈值，说明该 MME负载过大，此时该 MME没有为该 UE 服务的能力，则向 UE发送分离请求消息，或者，根据 UE所属群组标识判断该 UE所属群组并未租用该 MME, 则不能提供服务。 Step 102: The MME selects a network element device for the UE according to the group identifier to which the UE belongs. Specifically, the MME may determine that it can provide services for the UE according to some judgment conditions. For example, if the MME load exceeds a certain threshold, indicating that the MME is overloaded, and the MME does not have the capability to serve the UE, the MME sends a separation request message to the UE. Or, according to the group identifier of the UE, it is determined that the group to which the UE belongs does not rent the MME, and the service cannot be provided.

本实施例中，通过 MME在根据所述 UE的标识，获取所述 UE所属群组标识之后，根据所述 UE所属群组标识，为所述 UE选择网元设备，从而实现根据 UE所属群组标识为 UE选择与该 UE所属群组对应的网元设备，利于后续被选择的网元设备根据不用群组的差异 QoS、安全策略为 UE提供服务。选择的网元设备可以为 UE所属群组租用的设备，或者能够为该群组提供服务的网元设备。另外现有技术中，由于不对 UE的群组进行识别，而当选择网元设备时，选择了不能为该 UE提供服务的网元设备，会重新触发网元设备的选择流程。显然本实施例提供的方案由于根据 UE所属群组标识为 UE选择与该 UE所属群组对应的网元设备，该类网元设备是能够为 UE所属群组提供服务的，因此，避免了不必要的流程，提高了效率。 In this embodiment, after the MME obtains the group identifier of the UE according to the identifier of the UE, the network element device is selected for the UE according to the group identifier of the UE, thereby implementing the group according to the UE. The identifier is selected by the UE as the network element device corresponding to the group to which the UE belongs, so that the subsequently selected network element device provides services for the UE according to the differentiated QoS and security policy of the non-group. The selected network element device may be a device rented by a group to which the UE belongs, or an network element device capable of providing services for the group. In addition, in the prior art, since the group of the UE is not identified, when the network element device is selected, the network element device that cannot provide the service for the UE is selected, and the selection process of the network element device is restarted. It is obvious that the solution provided by the embodiment is that the network element device corresponding to the group to which the UE belongs is selected according to the group identifier of the UE, and the network element device can provide services for the group to which the UE belongs, thereby avoiding The necessary processes increase efficiency.

Figure 11, the method includes the following steps:

歩骤 300、演进型基站 eNB获得 UE的上下文，所述 UE的上下文包含所述 UE所属群组标识，所述 UE所属群组标识与所述 UE所属群组对应的移动性管理网元 MME具有对应关系； Step 300: The evolved base station eNB obtains the context of the UE, where the context of the UE includes the group identifier to which the UE belongs, and the group identity of the UE belongs to the mobility management network element MME corresponding to the group to which the UE belongs. Correspondence relationship

歩骤 301、所述 eNB根据所述 UE所属群组标识，为所述 UE选择所述 UE所属群组对应的移动性管理网元 MME。 Step 301: The eNB selects, for the UE, a mobility management network element MME corresponding to the group to which the UE belongs according to the group identifier to which the UE belongs.

本实施例提供的共享网络的用户设备识别方法，在 UE的标识为所述 UE 的 GUTI的场景中，通过 eNB获得用户设备 UE的上下文，所述 UE的上下文包含所述 UE所属群组标识，所述 UE所属群组标识与所述 UE所属群组对应的移动性管理网元 MME具有对应关系；所述 eNB根据所述 UE所属群组标识，为所述 UE选择所述 UE所属群组对应的移动性管理网元 MME。实现了根据 UE的标识选择相应 MME, 以使该 MME根据该 UE的标识准确地识别不同群组的 UE，将不同群组的 UE可以接入该群组专用的网络，提高了对于各个群组控制的准确性，进一歩的，更加利于后续对不同群组的 UE提供差异化 QoS、安全策略等服务。 In the scenario of the user equipment of the shared network provided by the embodiment, in the scenario that the identifier of the UE is the GUTI of the UE, the context of the user equipment UE is obtained by the eNB, and the context of the UE includes the group identifier of the UE. The group identity to which the UE belongs has a corresponding relationship with the mobility management network element MME corresponding to the group to which the UE belongs; the eNB selects, according to the group identifier of the UE, the group corresponding to the UE to which the UE belongs. Mobility Management Network Element MME. The MME is selected according to the identifier of the UE, so that the MME can accurately identify the UEs of different groups according to the identifier of the UE, and the UEs of different groups can access the network dedicated to the group, thereby improving the group for each group. Controlled Authentic, further, it is more conducive to the subsequent provision of differentiated QoS, security policies and other services for different groups of UEs.

需要说明的是，对于初始附着的过程（即，所述 UE的标识为所述 UE的 IMSI)时， eNB并不能无法进行 MME的选择，此时 eNB会随机选择 MME进行初始附着，当该 MME无法为相应 UE提供服务时，会将该 UE所属群组标识发送给 eNB , 以使 eNB根据 UE所属群组标识，为所述 UE选择所述 UE所属群组对应的移动性管理网元 MME。 It should be noted that, for the initial attach procedure (that is, the identifier of the UE is the IMSI of the UE), the eNB cannot select the MME, and the eNB randomly selects the MME to perform initial attach, when the MME When the service of the UE is not available, the group identity of the UE is sent to the eNB, so that the eNB selects the mobility management network element MME corresponding to the group to which the UE belongs according to the group identifier of the UE.

I Ή自、 .， I Ή自, .,

优选的，歩骤 300的一种可行的实现方式为： Preferably, a feasible implementation of the step 300 is:

歩骤 300a、所述 eNB根据所述 UE所属群组的对应信息获得所述 UE的上下文。 Step 301: The eNB obtains the context of the UE according to the corresponding information of the group to which the UE belongs.

可选地，在歩骤 301之后，还包括： Optionally, after step 301, the method further includes:

歩骤 303、所述 eNB向所述 MME发送所述附着请求消息。 Step 303: The eNB sends the attach request message to the MME.

可选地，在歩骤 303之后，还包括 Optionally, after step 303, the method further includes

歩骤 304、所述 eNB若获知所述负载能力最优的 MME不能接入所述 UE, 则指示所述 UE选择其他 MME中的一个进行接入。 Step 304: If the eNB learns that the MME with the best load capacity cannot access the UE, the eNB is instructed to select one of the other MMEs to access.

具体的， eNB中预先配置了每个运营商与各个 MME之间的对应关系，根据此对应关系可以指示 UE选择其他 MME进行接入，并且分配给用户设备的 GUTI也携带了可接入的 MME的信息。 Specifically, the corresponding relationship between each operator and each MME is pre-configured in the eNB, and according to the correspondence, the UE may be instructed to select another MME to perform access, and the GUTI allocated to the user equipment also carries the MME that can be accessed. Information.

例如，所述 eNB根据 UE上下文中包含 UE所属群组标识（PMNO ID ) 所指向的 MME正在进行用户迁移，即该 MME的指示为不可接入。此时需要 eNB指示 UE选择网络中其他可以为该群组服务的 MME进行接入。此处所述 eNB需要支持对该群组中各 MME状态与标识进行维护并根据 UE所属群组标识作出接入选择的功能。对于这种场景的交互流程，下文会给出具体的交互示例进行说明，具体的，图 12为本发明实施例提供的一种共享网络用户识别方法交互流程示意图，参照图 12，下面给出一个具体实例对于跟踪区更新（Tracking Area Updata ，简称： TAU) 场景，以对 MME不能接入所述 UE的情况进行说明： For example, the eNB performs user migration according to the MME pointed to by the UE context including the group identifier (PMNO ID) to which the UE belongs, that is, the indication of the MME is not accessible. At this time, the eNB is required to instruct the UE to select other MMEs in the network that can serve the group to access. The eNB needs to support the maintenance of each MME status and identity in the group and make an access selection according to the group identity to which the UE belongs. For the interaction process of the scenario, a specific interaction example will be described below. Specifically, FIG. 12 is a schematic diagram of an interaction process of a shared network user identification method according to an embodiment of the present invention. Referring to FIG. 12, a A specific example is a Tracking Area Updata (TAU) scenario, The description is made on the case where the MME cannot access the UE:

歩骤 400、 UE发起 TAU流程。 Step 400: The UE initiates a TAU process.

歩骤 401、 UE向 eNB发送跟踪区更新请求（Tracking Area Updata Request (old GUTI, additional GUTI, ) 消息发起 TAU过程，同时携带 RRC参数（所选择网络、旧全球唯一 MME标识（ Globally Unique MME Identifier, 简称： GUMMEI ) ) 。 Step 401: The UE sends a Tracking Area Updata Request (old GUTI, additional GUTI, ) message to the eNB to initiate a TAU process, and carries the RRC parameter (the selected network, the Globally Unique MME Identifier, Abbreviation: GUMMEI ) ).

具体的，如果该 TAU过程是由于负载重均衡而触发的，如果 UE的 TIN指示" GUTI"或" RAT-related TMSI-无线接入类型（radio access type, 简称： RAT ) 临时签约用户标识（Temporary Mobile Subscriber Identity, 简称： TMSI) "，且 UE保存有一个有效 GUTI, 旧 GUTI参数指示该有效 GUTIo如果 UE的 TIN指示" P-TMSI'，且 UE保存有一个有效 P-TMSI和相关联路由区标识（Routing Area Identification, 简称： RAI ) ，贝 lj旧 GUTI 参数由这两个参数构造。如果 UE处于连接模式重选到 E-UTRAN, UE必须将 TIN参数设置为" P-TMSI"。如果 UE保存有一个有效的 GUTI参数且旧 GUTI参数指示由 P-TMSI和 RAI构造的 GUTI, 贝 lj UE在附加 GUTI ( additional GUTI ) 参数设置为这个有效 GUTI值。如果旧 GUTI参数指示由 P-TMSI和 RAI构造的 GUTI, 且 UE保存有一个有效 P-TMSI签名，则必须在消息中包含 P-TMSI签名。 Specifically, if the TAU process is triggered by load re-equalization, if the TIN of the UE indicates "GUTI" or "RAT-related TMSI-radio access type (RAT) temporary subscription user identity (Temporary) Mobile Subscriber Identity, TMSI), and the UE holds a valid GUTI, the old GUTI parameter indicates the valid GUTIo if the UE's TIN indicates "P-TMSI", and the UE holds a valid P-TMSI and associated routing area. Routing Area Identification (RAI), the old GUTI parameter is constructed by these two parameters. If the UE is in the connected mode reselected to E-UTRAN, the UE must set the TIN parameter to "P-TMSI". If the UE There is a valid GUTI parameter saved and the old GUTI parameter indicates the GUTI constructed by P-TMSI and RAI, and the additional GUTI (addition GUTI) parameter is set to this valid GUTI value. If the old GUTI parameter is indicated by P-TMSI and For the GUI constructed by the RAI, and the UE holds a valid P-TMSI signature, the P-TMSI signature must be included in the message.

当旧 GUTI参数指示由 P-TMSI和 RAI构造的 GUTI时，附加 GUTI 参数允许新 MME能够査找其上所存储的 UE上下文。 When the old GUTI parameter indicates the GUTI constructed by P-TMSI and RAI, the additional GUTI parameter allows the new MME to look up the UE context stored thereon.

歩骤 402、 eNB从 RRC参数中的旧 GUMMEI和指示的已选择网络参数得到 MME。如果不能得到 MME, eNB就选择一个 MME。然后 eNB前转 TAU请求消息到新的 MME。 Step 402: The eNB obtains the MME from the old GUMMEI in the RRC parameter and the indicated selected network parameter. If the MME is not available, the eNB selects an MME. The eNB then forwards the TAU Request message to the new MME.

歩骤 403、新的 MME发送一个上下文请求（ Context Request(old GUTI) ) 消息给旧的 MME/S4-SGSN得到用户信息。新的 MME是从旧的 GUTI得到旧的 MME/S4-SGSN的。旧 MME使用完整的 TAU请求消息、 S4-SGSN使用 P-TMSI签名对 TAU请求消息进行完整性验证。新 MME 也可以对 TAU请求消息进行完整性保护验证，如果成功地鉴权了 UE, 新 MME必须向旧 MME/S4-SGSN发送上下文请求消息。 Step 403: The new MME sends a Context Request (old GUTI) message to the old MME/S4-SGSN to obtain user information. The new MME is the old MME/S4-SGSN from the old GUTI. The old MME uses the complete TAU request message, and the S4-SGSN uses the P-TMSI signature to perform integrity verification on the TAU request message. The new MME may also perform integrity protection verification on the TAU request message. If the UE is successfully authenticated, the new MME must send a context request message to the old MME/S4-SGSN.

歩骤 404、如果上下文请求是发送给旧 MME, 则旧的 MME返回一个上下文响应消息。 Step 404: If the context request is sent to the old MME, the old MME returns a Context response message.

如果上下文请求消息是发送给旧 S4-SGSN的，则旧 S4-SGSN发送上下文响应消息。在发送该消息之前 S4-SGSN将鉴权五元组复制到消息中。 ISR已支持参数指示了旧 S4-SGSN能够激活 ISR功能。 If the context request message is sent to the old S4-SGSN, the old S4-SGSN sends a context response message. The S4-SGSN copies the authentication quintuple into the message before sending the message. The ISR has supported parameters indicating that the old S4-SGSN can activate the ISR function.

可选的，歩骤 405、鉴权过程和加密过程。 Optionally, step 405, an authentication process, and an encryption process.

具体的，如果 TAU请求消息的完整性检査失败，则鉴权过程和加密过程是必须的。如果执行了 GUTI分配并且网络支持加密，贝 IJ非接入层 ( Non-access stratum, 简称： NAS ) 消息将被加密。 Specifically, if the integrity check of the TAU request message fails, the authentication process and the encryption process are necessary. If the GUTI allocation is performed and the network supports encryption, the Bell IJ Non-access stratum (NAS) message will be encrypted.

如果 UE处于连接管理-连接态（ECM-CONNECTED )发送 TAU请求消息，并且歩骤 402中 eNB发送的 TAI中 PLMN-ID不同于 TAU请求消息中的 GUTI中 PLMN-ID, MME必须将鉴权过程延迟到歩骤 420 ( TAU Complete )之后执行。 MME延迟鉴权过程的目的是在切换过程中 UE先将注册的 PLMN-ID更新到 RAN所选择的新 PLMN-ID。 MME在 TAU接受消息中的 GUTI参数中设置新 PLMN-ID。 If the UE is in the Connection Management-Connected State (ECM-CONNECTED) to send a TAU Request message, and the PLMN-ID in the TAI transmitted by the eNB in step 402 is different from the PLMN-ID in the GUTI in the TAU Request message, the MME must perform the authentication process. The delay is executed after step 420 (TAU Complete). The purpose of the MME delay authentication process is to update the registered PLMN-ID to the new PLMN-ID selected by the RAN in the handover process. The MME sets a new PLMN-ID in the GUTI parameter in the TAU accept message.

歩骤 406、新 MME向老 MME/老 S4-SGSN发送上下文通知。 Step 406: The new MME sends a context notification to the old MME/old S4-SGSN.

具体的，ΜΜΕ (若 MME发生改变则这个 ΜΜΕ是新 ΜΜΕ)决定 S-GW 重定位。旧 S-GW不能继续服务 UE时将发生 S-GW重定位。如果期望一个新的 S-GW服务 UE的时间更长一些，和 /或采用一个更为优化的 UE到 P-GW路径，或者要选择一个与 P-GW合设的新 S-GW, 则 ΜΜΕ也会决定 S-GW重定位。如果 ΜΜΕ已经改变，则新 ΜΜΕ发送上下文通知 [Context Acknowledge ( S-GW change indication) ]消息给旧 MME或旧 S4-SGSN。 S-GW Change indication标记指示已经选择了一个新的 S-GW。旧 MME或者旧 S4-SGN将 UE上下文中的网关相关信息标记为无效。如果旧节点是 MME,则旧 MME也会将 UE上下文中的 HSS相关信息标记为无效。其目的是如果此 TAU过程未完成而发生一个新的 TAU或 RAU过程回退到旧 MME或 S4-SGSN时旧 MME或 S4-SGSN能够更新网关，旧 MME能够更新 HSS。 Specifically, ΜΜΕ (this ΜΜΕ is new if the MME changes) determines the S-GW relocation. S-GW relocation occurs when the old S-GW cannot continue to serve the UE. If a new S-GW is expected to serve the UE for a longer period of time, and/or a more optimized UE-to-P-GW path is used, or a new S-GW to be selected with the P-GW is selected, then It also determines the S-GW relocation. If ΜΜΕ has changed, the new Context Acknowledge (S-GW change indication) message is sent to the old MME or the old S4-SGSN. The S-GW Change indication flag indicates that a new S-GW has been selected. The old MME or the old S4-SGN marks the gateway related information in the UE context as invalid. If the old node is the MME, the old MME also marks the HSS related information in the UE context as invalid. The purpose is that if the TAU process is not completed and a new TAU or RAU procedure falls back to the old MME or S4-SGSN, the old MME or S4-SGSN can update the gateway, and the old MME can update the HSS.

如果安全过程不能正确认证 UE，必须拒绝 TAU请求，并且新 MME 向旧 MME/S4-SGSN发送拒绝指示。旧 MME/S4-SGSN继续服务 UE。 If the security procedure fails to properly authenticate the UE, the TAU request must be rejected and the new MME sends a reject indication to the old MME/S4-SGSN. The old MME/S4-SGSN continues to serve the UE.

由于 S-GW改变而去激活 ISR,在 Context Acknowledge消息中不指示 ISR。 Deactivate the ISR due to the S-GW change, not indicated in the Context Acknowledge message ISR.

歩骤 407、新 MME向新 S-GW发送会话建立请求消息。 Step 407: The new MME sends a session establishment request message to the new S-GW.

具体的，如果 MME发生改变，则新 MME将从旧 MME/S4-SGSN所接收到的承载上下文与从 UE所接收到的 EPS承载状态进行验证。如果 MME没有改变，则 MME根据从 UE所接收到的 EPS承载状态与其保存的承载上下文进行验证。 MME将释放 UE中非激活 EPS承载的任何网络资源。如果根本就没有承载上下文，则 MME拒绝 TAU请求消息。 Specifically, if the MME changes, the new MME verifies the bearer context received from the old MME/S4-SGSN and the EPS bearer status received from the UE. If the MME has not changed, the MME performs verification according to the EPS bearer status received from the UE and its saved bearer context. The MME will release any network resources of the inactive EPS bearer in the UE. If there is no bearer context at all, the MME rejects the TAU request message.

如果 MME选择一个新 S-GW,它将基于每一 PDN连接发送会话建立请求消息 ( Create Session Request ( IMSI， bearer contexts , MME address and TEID , Type, the protocol type over S5/S8 , RAT type , Serving Network) ) 给所选择的 S-GW。在 bearer contexts中有 P-GW地址和业务流模板 If the MME selects a new S-GW, it will send a session establishment request message based on each PDN connection (IMSI, bearer contexts, MME address and TEID, Type, the protocol type over S5/S8, RAT type, Serving). Network)) to the selected S-GW. P-GW address and service flow template in bearer contexts

( Trafficfilter Template, 简称： TFT ) ( S5/S8 PMIP情形）信息。 Type向 S-GW指示器要发送创建会话消息（Create Session Request)给 P-GW。 The protocol type over S5/S8指示给 S-GW所选择的 S5/S8接口上协议类型。 RAT type指示了无线接入类型。如果 P-GW之前请求了 UE位置信息，则 MME也包含用户位置信息（User Location Identification, 简称： ULI IE) 。 (Trafficfilter Template, referred to as: TFT) (S5/S8 PMIP case) information. Type sends a Create Session Request to the S-GW indicator to the P-GW. The protocol type over S5/S8 indicates the protocol type on the S5/S8 interface selected by the S-GW. The RAT type indicates the type of wireless access. If the P-GW previously requested the UE location information, the MME also includes User Location Identification (ULI IE).

歩骤 408、 S-GW基于每一个公用数据网（Packet Data Network ，简称： PDN ) 连接向 P-GW发送修改承载请求消息（Modify Bearer Request ( S-GW address and TEID , RAT type, Serving Network) ) 以通知有关用于计费的 RAT类型之类的改变信息。如果 P-GW之前请求了上报用户位置信息，则 ULI IE也包含。 Step 408: The S-GW sends a Modify Bearer Request (S-GW address and TEID, RAT type, Serving Network) to the P-GW based on each Public Data Network (PDN) connection. ) to inform about the change information about the type of RAT used for charging. If the P-GW previously requested the reporting of user location information, the ULI IE is also included.

进一歩地，如果动态策略与计费控制（policy and charging control, 简称： PCC ) 部署的话， RAT类型信息需要传送给 PCRF, 然后 P-GW通过 IP-CAN会话修改过程发送该 RAT类型信息。 Further, if dynamic policy and charging control (PCC) is deployed, the RAT type information needs to be transmitted to the PCRF, and then the P-GW sends the RAT type information through the IP-CAN session modification process.

歩骤 409、 P-GW更新它的承载上下文并向 S-GW返回一条修改承载口向应 ( Modify Bearer Response (Mobile Station International Subscriber Directory Number， Charging Id) ) 消息。 Step 409: The P-GW updates its bearer context and returns a Modify Bearer Response (Mobile Station International Subscriber Directory Number, Charging Id) message to the S-GW.

歩骤 410、新 S-GW向新 MME返回创建会话响应消息 Step 410: The new S-GW returns a create session response message to the new MME.

具体的，新 S-GW 更新其承载上下文。这允许新 S-GW将来自 eNB 的承载 PDU路由到 P-GW。新 S-GW向新 MME返回创建会话响应消息。 Specifically, the new S-GW updates its bearer context. This allows the new S-GW to route bearer PDUs from the eNB to the P-GW. The new S-GW returns a Create Session Response message to the new MME.

歩骤 411、新 MME检査其是否有该 UE的签约数据。如果没有签约数据，则新 MME发送更新位置请求消息给 HSS。 ULR-Flags指示这次更新位置过程是从 MME发送的，并且在 HSS中更新 MME注册。 HSS不删除任何 SGSN注册。 MME capabilities指示 MME支持区域接入限制功能。 Homogeneous Support of IMSI over PS Sessions 旨示 MME所月艮务的所有 TA区域都支持" IMS Voice over PS Sessions"。 Step 411: The new MME checks whether there is subscription data of the UE. If there is no subscription data, the new MME sends an update location request message to the HSS. The ULR-Flags indicates that the update location procedure is sent from the MME and the MME registration is updated in the HSS. The HSS does not delete any SGSN registrations. The MME capabilities indicate that the MME supports the area access restriction function. Homogeneous Support of IMSI over PS Sessions The "IMS Voice over PS Sessions" are supported in all TA areas of the MME's monthly service.

歩骤 412、 HSS向旧 MME发送取消位置消息（ Cancel Location ( IMSI, Cancellation Type ) ) ，其 Cancellation Type设置为更新过程。 Step 412: The HSS sends a Cancel Location (IMSI, Cancellation Type) to the old MME, and the Cancellation Type is set to an update process.

歩骤 413、如果歩骤 403启动的定时器没工作时，旧的 MME清除移动性上下文。否则当定时器超时时 UE上下文被清除。这也确保了在正在进行的 TAU过程完成以前 UE回到旧 MME发起另外一个 TAU情况下仍然保存在旧的 MME里的 UE上下文有效。旧 MME回应取消位置应答 ( Cancel Location Ack ( IMSI ) ) 消息。 Step 413: If the timer started in step 403 is not working, the old MME clears the mobility context. Otherwise, the UE context is cleared when the timer expires. This also ensures that the UE context that is still stored in the old MME is valid when the UE returns to the old MME to initiate another TAU before the ongoing TAU procedure is completed. The old MME responds with a Cancel Location Ack (IMSI) message.

歩骤 414、旧 S4-SGSN接收到上下文应答（Context Acknowledge )消息，如果 UE处于 Iu连接（Iu Connected ) 状态，贝 lj旧 S4-SGSN在第 4歩定时器超时之后发送 Iu释放命令（Iu Release Command) 消息给 RNC。 Step 414: The old S4-SGSN receives a context acknowledgment (Context Acknowledge) message. If the UE is in the Iu Connected state, the old S4-SGSN sends an Iu release command after the 4th timer expires (Iu Release). Command) Message to the RNC.

歩骤 415、 RNC响应 Iu释放完成（Iu Release Complete ) 消息。 Step 415: The RNC responds to the Iu Release Complete message.

歩骤 416、 HSS发送给新 MME的更新位置应答（Update Location Ack (IMSI, Subscription Data) ) 消息来回应更新位置请求消息。如果更新位置请求被 HSS拒绝，则 MME拒绝来自 UE的 TAU请求并说明原因。 Step 416: The Update Location Ack (IMSI, Subscription Data) message sent by the HSS to the new MME responds to the update location request message. If the update location request is rejected by the HSS, the MME rejects the TAU request from the UE and explains the reason.

如果所有检査通过， MME构造 UE的移动性管理上下文。 If all checks pass, the MME constructs the mobility management context of the UE.

歩骤 417、如果 MME改变，当歩骤 403中启动的定时器超时，则旧 MME/S4-SGSN释放任何本地 MME或 SGSN承载资源，并且如果在上下文应答消息（Context Acknowledge ) 中接收到 S-GW改变指示信息，则旧 MME/S4-SGSN向旧 S-GW发送删除会话请求消息（Delete Session Request ( Cause ) )以指示删除 EPS承载资源。 Cause值指示旧 S-GW不要向 P-GW 启动删除过程。如果 ISE激活，则 Cause值指示旧 S-GW向另外一个核心网节点发送删除承载请求消息（Delete Bearer Request) 以删除该节点上的承载资源。如果 MME不改变而新 S-GW改变，歩骤 410触发释放 EPS承载资源。 Step 417: If the MME changes, when the timer started in step 403 times out, the old MME/S4-SGSN releases any local MME or SGSN bearer resources, and if S- is received in the context response message (Context Acknowledge) The GW changes the indication information, and the old MME/S4-SGSN sends a Delete Session Request ( Cause ) message to the old S-GW to indicate deletion of the EPS bearer resource. The Cause value indicates that the old S-GW does not initiate the deletion process to the P-GW. If the ISE is activated, the Cause value indicates that the old S-GW sends a Delete Bearer Request message to another core network node to delete the bearer resources on the node. If the MME does not change and the new S-GW changes, step 410 triggers the release of the EPS bearing. Carrying resources.

歩骤 418、 S-GW回应删除会话响应消息（Delete Session Response ( cause ) ) ， S-GW丢弃为 UE所缓冲的任何分组包。 Step 418: The S-GW responds with a Delete Session Response (cause) message, and the S-GW discards any packet buffered by the UE.

歩骤 419、如果由于区域签约限制或者接入限制，不允许 UE接入到该 TA区域： Step 419: If the area is restricted by the area or the access restriction, the UE is not allowed to access the TA area:

- 则 MME以合适的理由拒绝 TAU请求消息。 - Then the MME rejects the TAU Request message for a suitable reason.

否则 MME向 UE回应跟踪区更新接受（TAU Accept(GUTI， TAI-list, EPS bearer status , NAS sequence number, NAS -MAC, ISR Activated, IMS Voice over PS session supported) )消息。如果 TAU请求消息中激活标记设置，切换限制列表会发送给 eNB，因为 eNB处理 Intm-E-UTRAN情形下的漫游限制和接入限制，并且用户面建立过程与 TAU接受消息一起进行。 EPS承载状态指示了网络中激活的承载。如果 ISR已激活被设置，表明 P-TMSI和 RAI标识在网络仍然注册有效。在 MME改变的 TAU过程中 ISR 已激活不可以包含。在 MME不改变的 TAU过程中，如果 MME接收到 TAU请求时 ISR处于激活状态， MME应该在 TAU接受消息中包含 ISR 已激活并维持 ISR激活状态。 Otherwise, the MME responds to the UE with a message of the tracking area update accepting (NAS, MAC-Isert, IMS Voice over PS session) message. If the TAU request message activates the flag setting, the handover restriction list is sent to the eNB because the eNB handles the roaming restriction and access restriction in the Intm-E-UTRAN case, and the user plane establishment process is performed together with the TAU accept message. The EPS bearer status indicates the active bearer in the network. If the ISR is activated, it indicates that the P-TMSI and RAI flags are still valid for registration on the network. The ISR is activated during the TAU change of the MME and cannot be included. In the TAU process in which the MME does not change, if the ISR is in the active state when the MME receives the TAU request, the MME should include the ISR activated and maintain the ISR activation state in the TAU accept message.

当接收到 TAU接受消息中没有 ISR已激活指示， UE将 TIN设置为 "GUTI'O 如果包含有 ISR已激活指示， UE的 TIN标识指示" GUTI" , 则该值不改变。如果包含有 ISR已激活指示， UE的 TIN标识指示" P-TMSI' '或 "RAT-related TMSI" , 贝 lj UE必须设置 TIN为" RAT-related TMSI"。 When there is no ISR activated indication in the received TAU accept message, the UE sets the TIN to "GUTI'O. If the ISR activated indication is included, and the UE's TIN identifier indicates "GUTI", the value does not change. If the ISR is included The activation indication, the TIN identity of the UE indicates "P-TMSI" or "RAT-related TMSI", and the UE must set the TIN to "RAT-related TMSI".

在 MME改变情形下，新 MME不激活 ISR避免在两个旧核心网节点之间进行上下文传输过程。 In the case of MME change, the new MME does not activate the ISR to avoid the context transfer process between the two old core network nodes.

歩骤 420、如果 GUTI改变， UE通过返回跟踪区更新完成（TAU Complete )消息给 MME确认。如果在 TAU请求消息中设置激活标记，这个 TAU过程不是在 ECM-CONNECTED状态发起的，贝 I」 MME释放与 UE 的信令连接。 Step 420: If the GUTI changes, the UE returns a Tracking Area Update Complete (TAU Complete) message to the MME for confirmation. If the activation flag is set in the TAU request message, the TAU procedure is not initiated in the ECM-CONNECTED state, and the MME releases the signaling connection with the UE.

下面通过具体实施例对于用户设备、 MME、 eNB以及 HSS实现本实施例提供的基于参与群组标识的接入方法过程中的交互流程进行具体说明。图 13为本发明实施例提供的一种基于参与群组标识的接入方法交互流程示意图，参照图 13可知，该网络中包含 UE、 eNB , MME1、 MME2、 SGW/PGW以及 HSS。假设 UE、 MME1、 MME2、 SGW/PGW以及 HSS 均属于群组 1，网络中也可以包含属于其他群组的网元设备，图 13中并未示出。参照图 13，该交互流程包括如下歩骤： The interaction process in the process of participating in the group identity-based access method provided in this embodiment is specifically described in the following by using a specific embodiment for the user equipment, the MME, the eNB, and the HSS.
