用于远程接入本地网络的方法及装置 Method and device for remote access to local network

本申请要求于 2012 年 4 月 28 日提交中国专利局、申请号为 201210142510.3、名称为 "用于远程接入本地网络的方法及装置"的中国专利申请的优先权，其全部内容通过引用结合在本申请中。 This application claims priority to Chinese Patent Application No. 201210142510.3, entitled "Method and Apparatus for Remote Access to Local Network", filed on April 28, 2012, the entire contents of In this application.

技术领域本发明涉及通信技术领域，特别涉及一种用于远程接入本地网络的方法及装置。背景技术 TECHNICAL FIELD The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for remote access to a local network. Background technique

在移动通信***中， 3GPP在节点 B (Node B,简称 NB) 和演进型节点 B (evolved Node B,简称 eNB) 的基础上提出了家庭（演进型）节点 B (Home (evolved) Node B，简称 H(e)NB ) 的概念， H(e)NB主要应用于家庭与企业环境下，在 H(e)NB的需求中，包含了一类本地 IP接入（LIPA， Local IP Access) 业务。本地 IP接入是指具有 IP能力的用户设备（UE， User Equipment) 通过 H(e)NB无线接入到相同家庭 /企业 IP网络的其他具有 IP能力的实体中。本地 IP接入中业务数据的执行，不通过运营商的核心网。 In the mobile communication system, 3GPP proposes a Home (evolved) Node B based on a Node B (Node B, NB for short) and an evolved Node B (eNB). Referred to as H(e)NB), H(e)NB is mainly used in home and enterprise environments. In the H(e)NB requirements, it includes a type of local IP access (LIPA) service. . Local IP access refers to IP-enabled user equipment (UE, User Equipment) wirelessly accessing other IP-capable entities of the same home/enterprise IP network through H(e)NB. The execution of service data in local IP access does not pass through the carrier's core network.

在本地网络（ LHN， Local H(e)NB Network )中定义了一系列的 H(e)NB。这些 H(e)NB与一个或多个本地网关（L-GW， Local Gateway)有 IP连接。这些 L-GW可以通过本地分组数据网络（PDN(s)， Packet Data Network(s))进行 LIPA。同时，一个 H(e)NB只属于一个单独的 LHN, —个 L-GW只属于一个单独的 LHN, —个 L-GW可接入一个多几个 PDNs。并且，可以通过多个 LHNs 接入一个 PDN。 A series of H(e)NBs are defined in the local network (LHN, Local H(e)NB Network). These H(e)NBs have an IP connection with one or more local gateways (L-GW, Local Gateway). These L-GWs can perform LIPA through a local packet data network (PDN(s), Packet Data Network(s)). At the same time, one H(e)NB belongs to only one single LHN, and one L-GW belongs to only one single LHN, and one L-GW can access one more PDNs. Also, one PDN can be accessed through multiple LHNs.

针对 L-GW还提出了新的网络架构。在该新的架构中 L-GW是一个本地网络中新的单独的逻辑实体，它通过 S5接口连接到服务网关（S-GW)或服务 GPRS支持节点（ Serving GPRS Support Node, SGSN)，同时 L-GW通过一个新的 Sxx接口连接到 H(e)NB。除了本地 IP接入外，还提出了具有 IP能力的 UE远程接入到家庭 /企业 IP 网络中其他具有 IP能力的实体中的需求，即远程接入本地网络的需求。这种远程接入本地网络的业务可以被称为被管理的远程接入（MRA， Managed Remote Access) 业务。例如，该业务可以是通过移动终端如手机远程接入家庭网络访问家里的电脑，以与朋友分享周末出去游玩拍摄的视频。此时我们称家庭 /企业 IP 网络为本地网络，该本地网络可以包括 H(e)NB，本地网关及其他 IP 设备，如家庭 /企业中的电脑等；其中，当不在本地网络里接入家庭 / 企业 IP网络时，称其为远程接入本地网络；而当移动到本地网络后接入家庭 / 企业 IP网络时，称其为本地 IP接入。现有技术并未给出能够实现通过用户设备远程接入本地网络的方法。发明内容 A new network architecture has also been proposed for L-GW. In this new architecture, the L-GW is a new separate logical entity in the local network, which is connected to the Serving GPRS Support Node (SGSN) via the S5 interface or the Serving GPRS Support Node (SGSN). -GW connects to H(e)NB via a new Sxx interface. In addition to local IP access, there is also a need for IP-capable UEs to remotely access other IP-capable entities in the home/enterprise IP network, ie the need to remotely access the local network. Such remote access to the local network's services may be referred to as Managed Remote Access (MRA) services. For example, the service may be to access a home computer through a mobile terminal such as a mobile phone remote access home network to share a video of a weekend trip with friends. At this point, we refer to the home/enterprise IP network as the local network. The local network can include H(e)NB, local gateway and other IP devices, such as computers in the home/enterprise; where, when the home network is not connected to the home network / Enterprise IP network, which is called remote access to the local network; when it is connected to the local network and access the home/enterprise IP network, it is called local IP access. The prior art does not teach a method that enables remote access to a local network through a user equipment. Summary of the invention

下面将结合附图详细描述本发明的各个实施例。图 1是根据本发明实施例的用于远程接入本地网络的方法的流程图。图 1 所示出的本发明实施例的用于远程接入本地网络的方法包括如下歩骤： Various embodiments of the present invention will be described in detail below with reference to the drawings. 1 is a flow chart of a method for remote access to a local network in accordance with an embodiment of the present invention. The method for remotely accessing a local network in the embodiment of the present invention shown in FIG. 1 includes the following steps:

歩骤 110，接收用户设备发送的分组数据网络（PDN， Packet Data Network) 连接请求，其中，连接请求中包括：远程接入标识信息，该远程接入标识信息用于标识用户设备进行的接入为远程接入；示例性地，远程接入标识信息可以是远程接入点的标识信息，用于对进行远程接入的接入点进行指示；具体地，例如可以为远程接入点名（APN， Access Point Name ) 。 Step 110: Receive a packet data network (PDN) connection request sent by the user equipment, where the connection request includes: remote access identifier information, where the remote access identifier information is used to identify the access performed by the user equipment. For example, the remote access identifier information may be the identifier information of the remote access point, and is used to indicate the access point that performs remote access; specifically, for example, the remote access point name (APN) , Access Point Name ).

歩骤 120，至少根据所述远程接入标识信息获知所述用户设备请求建立远程分组数据网络连接。 Step 120: Obtain, according to the remote access identifier information, that the user equipment requests to establish a remote packet data network connection.

歩骤 130，确定所述用户设备可以远程接入第一本地网络。 Step 130: Determine that the user equipment can remotely access the first local network.

该歩骤中，如果所述连接请求中包括第一本地网络的信息，并且所述用户设备的签约数据指示所述用户设备允许远程接入所述第一本地网络，则确定所述用户设备可以远程接入第一本地网络；其中，连接请求中包括的本地网络的信息通常为用户设备想要接入的本地网络的信息；第一本地网络的信息用于对第一本地网络进行指示。如果所述连接请求中不包括对本地网络进行指示的本地网络信息，则将默认的本地网络确定为所述第一本地网络，所述默认的本地网络为所述用户设备的签约数据中所指示的所述用户设备允许远程接入的默认本地网络。 In this step, if the connection request includes information of the first local network, and the subscription data of the user equipment indicates that the user equipment allows remote access to the first local network, determining that the user equipment may Remotely accessing the first local network; wherein the information of the local network included in the connection request is usually information of a local network that the user equipment wants to access; and the information of the first local network is used to indicate the first local network. If the connection request does not include local network information indicating the local network, determining a default local network as the first local network, where the default local network is indicated in the subscription data of the user equipment The user equipment allows a default local network for remote access.

歩骤 140，选择第一本地网络下的第一本地网关。歩骤 150，发送第一创建会话请求，所述第一创建会话请求包含所述第一本地网关的地址，以通过所述第一本地网关建立到所述第一本地网络的分组数据网络连接。 Step 140: Select a first local gateway under the first local network. Step 150: Send a first create session request, where the first create session request includes an address of the first local gateway to establish a packet data network connection to the first local network by using the first local gateway.

优选地，在歩骤 130确定所述用户设备可以远程接入第一本地网络之前，获取用户设备的签约数据。其中，示例性地，可以是在歩骤 110之前或与在执行歩骤 110的同时，获取上述签约数据。 Preferably, before the step 130 determines that the user equipment can remotely access the first local network, the subscription data of the user equipment is obtained. For example, the contract data may be obtained before the step 110 or concurrently with the execution of the step 110.

其中，上述签约数据至少包括：远程接入允许信息和允许远程接入的本地网络的信息中的一项。可以用一远程接入标识来标示是否允许进行远程接入，当远程接入标识设置成第一值时，标识 UE允许进行远程接入；当远程接入标识设置成第二值时，标识 UE不允许进行远程接入。 The foregoing subscription data includes at least one of: remote access permission information and information of a local network that allows remote access. A remote access identifier may be used to indicate whether remote access is allowed. When the remote access identifier is set to a first value, the UE is allowed to perform remote access; when the remote access identifier is set to a second value, the UE is identified. Remote access is not allowed.

在一种实现中，签约数据可以包括：远程接入允许信息和允许远程接入的本地网络的信息两者。根据远程接入允许信息确定 UE允许进行远程接入；根据允许接入的本地网络信息来确定 UE是否允许接入 UE想要接入的第一本地网络。 In one implementation, the subscription data can include: both remote access permission information and information of a local network that allows remote access. Determining, according to the remote access permission information, that the UE allows remote access; determining whether the UE allows access to the first local network that the UE wants to access according to the local network information that is allowed to access.

在另一种具体实现中，签约数据可以只包括远程接入允许信息。可以设置成，当签约数据包括远程接入允许信息时，表示 UE允许远程接入任何本地网络。 In another specific implementation, the subscription data may include only remote access permission information. It may be set that when the subscription data includes remote access permission information, it indicates that the UE allows remote access to any local network.

在又一种具体实现中，签约数据可以只包括允许远程接入的本地网络的信息。可以设置成，当 UE的签约数据中包括该信息时，即表示 UE允许远程接入该本地网络。 In yet another specific implementation, the subscription data may only include information of the local network that is allowed to access remotely. It may be set that when the UE includes the information in the subscription data, it indicates that the UE allows remote access to the local network.

上述第一本地网络的信息可以是，例如，第一本地网络的标识、第一本地网络的名称等。 The information of the first local network may be, for example, an identifier of the first local network, a name of the first local network, and the like.

在本发明的另一个实施例中，如果用户设备想要接入的本地网络为第一本地网络，并且用户设备已经签约允许远程接入多个本地网络，在这种情况下，当用户设备允许远程接入的多个本地网络中包括第一本地网络时，确定用户设备可以远程接入第一本地网络。 In another embodiment of the present invention, if the local network that the user equipment wants to access is the first local network, and the user equipment has subscribed to allow remote access to multiple local networks, in this case, when the user equipment allows When the first local network is included in multiple local networks of remote access, it is determined that the user equipment can remotely access the first local network.

本发明实施例的方法可以由移动管理实体（MME, Mobile Management Entity) 来执行。 The method of the embodiment of the present invention may be performed by a Mobile Management Entity (MME).

图 2是根据本发明另一实施例的用于远程接入本地网络的方法的流程图。图 2所示的本发明实施例的用于远程接入本地网络的方法包括如下歩骤：歩骤 210，接收用户设备发送的分组数据网络连接请求，其中，连接请求中包括用户设备想要接入的第一本地网关的地址的信息。 2 is a flow chart of a method for remote access to a local network in accordance with another embodiment of the present invention. The method for remotely accessing a local network in the embodiment of the present invention shown in FIG. 2 includes the following steps: Step 210: Receive a packet data network connection request sent by the user equipment, where the connection request includes information about an address of the first local gateway that the user equipment wants to access.

歩骤 220，根据第一本地网关的地址信息，获知所述用户设备请求建立远程分组数据网络连接。 Step 220: Obtain, according to the address information of the first local gateway, that the user equipment requests to establish a remote packet data network connection.

该歩骤中，示例性地，可以通过判断第一本地网关与所述用户设备的接入基站是否直接连接来获知用户设备是否请求远程分组数据网络连接；如果第一本地网关与所述用户设备的接入基站不是直接连接，则可以知道用户设备请求建立远程分组数据网络连接；如果第一本地网关与所述用户设备的接入基站是直接连接，则可以知道用户设备请求建立的不是远程分组数据网络连接。 In this step, by way of example, it may be determined whether the user equipment requests a remote packet data network connection by determining whether the first local gateway is directly connected to the access base station of the user equipment; if the first local gateway and the user equipment If the access base station is not directly connected, it can be known that the user equipment requests to establish a remote packet data network connection; if the first local gateway is directly connected to the access base station of the user equipment, it can be known that the user equipment requests to establish not a remote grouping Data network connection.

歩骤 230，如果用户设备的签约数据指示用户设备允许远程接入所述第一本地网关，则确定所述用户设备可以远程接入所述第一本地网关。 Step 230: If the subscription data of the user equipment indicates that the user equipment allows remote access to the first local gateway, determining that the user equipment can remotely access the first local gateway.

歩骤 240，发送第一创建会话请求，所述第一创建会话请求包含所述第一本地网关的地址，以通过所述第一本地网关建立到第一本地网络的分组数据网络连接。 Step 240: Send a first create session request, where the first create session request includes an address of the first local gateway to establish a packet data network connection to the first local network by using the first local gateway.

优选地，在歩骤 230之前，获取用户设备的签约数据。示例性地，可以是在歩骤 210之前或者在执行歩骤 210的同时，获取上述签约数据。其中，上述签约数据至少包括：远程接入允许信息和允许远程接入的本地网关的地址信息中的一项。优选地，在另一实施例中，上述第一本地网关的地址信息可以是用户设备在发送分组数据网络连接请求前从服务器中获得的。具体的获得方式可以是用户设备将想要接入的第一本地网络的标识或名称发送到能对标识或名称进行解析的服务器，由该服务器对第一本地网络的标识或名称进行解析，并将解析后获得的该第一本地网络下的第一本地网关的地址的信息发送至用户设备。用户设备接收上述第一本地网关的地址。然后，用户设备可以直接在上述连接请求中包含该第一本地网关的地址，从而接收该连接请求的装置如移动管理实体则无需再获取该第一本地网关的地址。 Preferably, before the step 230, the subscription data of the user equipment is obtained. Illustratively, the subscription data may be obtained prior to step 210 or while step 210 is being performed. The foregoing subscription data includes at least one of: remote access permission information and address information of a local gateway that allows remote access. Preferably, in another embodiment, the address information of the first local gateway may be obtained by the user equipment from the server before sending the packet data network connection request. The specific obtaining manner may be that the user equipment sends the identifier or name of the first local network that the user equipment wants to access to a server that can resolve the identifier or the name, and the server analyzes the identifier or name of the first local network, and Sending information of the address of the first local gateway under the first local network obtained after parsing to the user equipment. The user equipment receives the address of the first local gateway. Then, the user equipment can directly include the address of the first local gateway in the connection request, so that the device that receives the connection request, such as the mobility management entity, does not need to acquire the address of the first local gateway.

图 3是本发明另一实施例的用于远程接入本地网络的方法的流程图。图 3 所示的方法包括如下歩骤： 3 is a flow chart of a method for remote access to a local network in accordance with another embodiment of the present invention. The method shown in Figure 3 includes the following steps:

歩骤 301， UE发送附着请求消息或者跟踪区更新请求消息，该附着请求消息或者跟踪区更新请求消息中包含用户标识，例如国际移动用户标识 (IMSI, International Mobile Subscriber Identity)或全球唯一临时标识（GUTI, Globally Unique Temporary Identity)。 Step 301: The UE sends an attach request message or a tracking area update request message, where the attach request message or the tracking area update request message includes a user identifier, such as an International Mobile Subscriber Identity (IMSI) or a globally unique temporary identifier ( GUTI, Globally Unique Temporary Identity).

歩骤 302， MME向归属用户服务器（HSS， Home Subscriber Server) 发送更新位置请求消息，其中携带当前 MME的标识。 Step 302: The MME sends an update location request message to the Home Subscriber Server (HSS), where the MME carries the identifier of the current MME.

歩骤 303， HSS向 MME回复更新位置确认消息，其中携带 UE的签约数据。该实施例中，该签约数据至少包括如下信息中的一项：远程接入允许信息，例如 UE的 MRA允许标识；以及允许远程接入的本地网络的信息，例如可以是 UE允许远程接入的本地网络的标识或名称。其中，远程接入允许信息可以指示用户设备是否允许使用远程接入本地网络业务；允许远程接入的本地网络的信息可以指示哪些本地网络允许用户设备进行远程接入。 Step 303: The HSS returns an update location confirmation message to the MME, where the UE carries the subscription data of the UE. In this embodiment, the subscription data includes at least one of the following information: remote access permission information, such as an MRA permission identifier of the UE; and information of a local network that allows remote access, for example, the UE may allow remote access. The ID or name of the local network. The remote access permission information may indicate whether the user equipment allows remote access to local network services; the information of the local network that allows remote access may indicate which local networks allow the user equipment to perform remote access.

歩骤 304， MME向 UE回复附着接受消息或跟踪区更新接受消息。 Step 304: The MME replies to the UE with an attach accept message or a tracking area update accept message.

歩骤 305， UE确定当前进行的接入为远程接入。 Step 305: The UE determines that the currently performed access is remote access.

示例性地，该歩骤可以包括 UE判断 UE的当前服务小区是否属于本地网络；如果不属于本地网络，则 UE可以确定是要进行远程本地接入；如果属于本地网络，则可以进一歩判断该本地网络与 UE想要接入的本地网络是否相同；如相同，则要进行的不是远程接入；如不同，则要进行的是远程接入。 Exemplarily, the step may include the UE determining whether the current serving cell of the UE belongs to the local network; if not belonging to the local network, the UE may determine that the remote local access is to be performed; if it belongs to the local network, the UE may further determine Whether the local network is the same as the local network that the UE wants to access; if it is the same, it is not remote access; if it is different, it is remote access.

示例地，在 UE的当前服务小区有本地网络信息的情况下，可以通过判断 UE的当前服务小区为本地网络（也称为第二本地网络），并且可以进一歩根据该本地网络的信息判断该第二本地网络与 UE想要接入的第一本地网络是否相同来确定是否进行远程接入；如果相同，则进行的不是远程接入业务；如果不同，则进行的是远程接入业务。 For example, in a case where the current serving cell of the UE has local network information, it may be determined that the current serving cell of the UE is a local network (also referred to as a second local network), and may further determine the information according to the information of the local network. Whether the second local network is the same as the first local network that the UE wants to access to determine whether to perform remote access; if the same, the remote access service is not performed; if not, the remote access service is performed.

具体地，该歩骤可以包括： UE获得当前服务小区的本地网络（也称为第二本地网络）的信息，该信息可以是第二本地网络的标识；在比较该第二本地网络的标识与想要接入的第一本地网络的标识是否相同，以判断第二本地网络与第一本地网络是否相同；如果两者的标识相同，则获知 UE进行的是本地 IP 接入业务；否则，获知 UE进行的是远程接入业务。 Specifically, the step may include: obtaining, by the UE, information about a local network (also referred to as a second local network) of the current serving cell, where the information may be an identifier of the second local network; comparing the identifier of the second local network with Whether the identity of the first local network that is to be accessed is the same, to determine whether the second local network is the same as the first local network; if the identifiers of the two are the same, it is learned that the UE performs the local IP access service; otherwise, it is known The UE performs a remote access service.

示例性地，对于当前服务小区有本地网络信息的情况， UE可以通过接收 ***广播消息或者无线资源控制（RRC, Radio Resource Control) 消息来获得上述第二本地网络的标识。 For example, in a case where the current serving cell has local network information, the UE may obtain the identifier of the second local network by receiving a system broadcast message or a Radio Resource Control (RRC) message.

或者，在另一个示例中，也可以是 UE的当前服务小区没有本地网络信息，即当前服务小区不属于任何一个本地网络；则对于这种情况，如果 UE想要接入一本地网络，则可以知道 UE进行的是远程接入业务。具体地，例如，如果 UE当前的服务小区是一个宏基站，不是家庭（演进型）基站，而 UE要通过宏基站接入本地网络，则可以知道 UE进行的是远程接入本地网络业务。 Or, in another example, the current serving cell of the UE does not have local network information, that is, the current serving cell does not belong to any local network; After entering a local network, it can be known that the UE performs a remote access service. Specifically, for example, if the current serving cell of the UE is a macro base station, not a home (evolved type) base station, and the UE is to access the local network through the macro base station, it may be known that the UE performs remote access to the local network service.

歩骤 306，如果 UE确定出当前进行的是远程接入业务，则其发起 PDN连接请求，该 PDN连接请求中包含：远程接入标识信息和第一本地网络的信息，其中，该第一本地网络为 UE想接入的本地网络，该第一本地网络的信息用于对第一本地网络进行指示。 Step 306: If the UE determines that the remote access service is currently being performed, it initiates a PDN connection request, where the PDN connection request includes: remote access identification information and information of the first local network, where the first local The network is a local network that the UE wants to access, and the information of the first local network is used to indicate the first local network.

其中，远程接入标识信息可以是远程接入点的标识信息，用于对进行远程接入的接入点进行指示，例如可以是 MRA APN的信息。第一本地网络的信息可以是第一本地网络的标识（local network identity)信息或名称 ( local network name )。 The remote access identifier information may be identifier information of the remote access point, and is used to indicate an access point that performs remote access, for example, information of the MRA APN. The information of the first local network may be the first local network identity information or the name (local network name).

歩骤 307a， MME根据上面所获得的签约数据中的远程接入允许信息获知 UE可以建立远程 PDN连接，例如建立 MRA业务的连接，并通过将签约数据中允许接入的本地网络的信息（例如网络标识或网络名称）与 UE携带的想要接入的第一本地网络的标识或名称的信息进行对比来确定 UE是否可以远程接入第一本地网络，以对 UE的接入进行控制；如果第一本地网络为签约数据中 UE允许远程接入的本地网络，则确定允许 UE远程接入第一本地网络，否贝 lj，不允许 UE远程接入第一本地网络。 Step 307a: The MME learns, according to the remote access permission information in the subscription data obtained above, that the UE can establish a remote PDN connection, for example, establishes a connection of the MRA service, and obtains information about the local network that is allowed to access in the subscription data (for example, The network identifier or the network name is compared with the information of the identifier or the name of the first local network that the UE wants to access to determine whether the UE can remotely access the first local network to control the access of the UE; The first local network is a local network in the subscription data that the UE allows remote access, and then determines to allow the UE to remotely access the first local network, and does not allow the UE to remotely access the first local network.

歩骤 307b，在确定 UE允许远程接入第一本地网络的情况下，选择第一本地网关；其中，第一本地网关为第一本地网络下的本地网关。示例性地，可以根据第一本地网络的信息如标识或名称获得第一本地网关的地址，即能接入第一本地网络的第一本地网关的地址，并将该第一网关的地址发送给服务网关 (S-GW) o Step 307b: In the case that it is determined that the UE allows remote access to the first local network, the first local gateway is selected; wherein the first local gateway is a local gateway under the first local network. Exemplarily, the address of the first local gateway may be obtained according to the information of the first local network, such as the identifier or the name, that is, the address of the first local gateway that can access the first local network, and the address of the first gateway is sent to Service Gateway (S-GW) o

该歩骤中，具体地， MME可以通过查询本地网络与对应的本地网关的地址之间的对应关系来得到与第一本地网络相对应的第一本地网关的地址。示例性地， MME可以采用多种方式查询得到第一本地网络的标识或名称与第一本地网关的地址的关系。例如， MME可以使用域名服务器（DNS， Domain Name Server) ***进行查询，该 DNS上预先存储网络标识或名称与 L-GW地址之间的关系， MME可以将第一本地网络信息发送至 DNS,由 DNS进行解析后，将第一本地网关的地址返回 MME; 还可以是在 MME上预先存储上述本地网络与本地网关的地址之间的对应关系，由 MME根据自身所存储关系进行查询; 或者， MME 还可以根据以前查询到的历史数据来获得第一本地网关的地址，上述历史数据包括以前查询到的本地网络与对应的本地网关的对应关系。 In this step, specifically, the MME may obtain the address of the first local gateway corresponding to the first local network by querying the correspondence between the local network and the address of the corresponding local gateway. Exemplarily, the MME may query, in multiple manners, the relationship between the identifier or name of the first local network and the address of the first local gateway. For example, the MME may perform a query by using a Domain Name Server (DNS) system, where the relationship between the network identifier or the name and the L-GW address is pre-stored, and the MME may send the first local network information to the DNS. After the DNS is parsed, the address of the first local gateway is returned to the MME; or the local network is pre-stored on the MME. The MME can also perform the query according to the stored relationship of the local gateway. Alternatively, the MME can obtain the address of the first local gateway according to the historical data previously queried. The historical data includes the previous query. Correspondence between the local network and the corresponding local gateway.

歩骤 308， MME发送第一创建会话请求给服务网关 S-GW; 其中，第一创建会话请求中包含第一本地网关的地址和远程接入指示信息；该远程接入指示信息用于指示当前进行的接入为远程接入。例如，该远程接入指示信息可以是 MRA业务标识，该 MRA业务标识用于指示当前进行的接入为 MRA业务。 Step 308: The MME sends a first create session request to the serving gateway S-GW. The first create session request includes an address of the first local gateway and remote access indication information. The remote access indication information is used to indicate the current The access made is remote access. For example, the remote access indication information may be an MRA service identifier, where the MRA service identifier is used to indicate that the currently performed access is an MRA service.

歩骤 309， S-GW接收第一创建会话请求，并根据第一创建会话请求中包含的第一本地网关的地址发送第二创建会话请求给第一本地网关。该第二创建会话请求中包含远程接入指示信息。 Step 309: The S-GW receives the first create session request, and sends a second create session request to the first local gateway according to the address of the first local gateway included in the first create session request. The second creation session request includes remote access indication information.

歩骤 310，第一本地网关接收第二创建会话请求消息，并根据该消息中的远程接入指示信息获知该业务为远程接入业务。然后，可选地，第一本地网关可以生成基于远程接入业务的计费模式，以进行远程接入业务的计费。该计费模式可以与基于本地 IP接入业务的计费模式不同。或者，可选地，第一本地网关还可以基于本地资源的情况，生成远程接入业务的服务质量（QoS， Quality of Service )₀ 示例性地，在资源紧张时可以基于不同的业务类型进行优先级处理，例如，该优先级可以是本地接入业务的优先级高于远程接入的优先级。 Step 310: The first local gateway receives the second create session request message, and learns, according to the remote access indication information in the message, that the service is a remote access service. Then, optionally, the first local gateway may generate a charging mode based on the remote access service to perform charging of the remote access service. The charging mode may be different from the charging mode based on the local IP access service. Or, alternatively, it may also be based on the first local gateway when local resources, generating a remote access service quality of service (QoS, Quality _of Service) ₀ example, a priority may be based on different traffic types upon resource constraints Level processing, for example, the priority may be that the priority of the local access service is higher than the priority of the remote access.

歩骤 311，第一本地网关回复创建会话响应至服务网关，其中会话响应中可以携带所生成的远程接入业务的服务质量，例如 MRA QoS。 Step 311: The first local gateway replies to create a session response to the serving gateway, where the session response may carry the quality of service of the generated remote access service, such as MRA QoS.

歩骤 312，建立无线侧及核心网侧承载，以实现 UE通过第一本地网关建立到第一本地网络的 PDN连接。 Step 312: Establish a radio side and a core network side bearer, so that the UE establishes a PDN connection to the first local network through the first local gateway.

可选地，在该实施例中， UE发起远程接入时，在 PDN连接请求中可以不携带 UE想要接入的本地网络的信息。在这种情况下， MME可以将默认的本地网络当作 UE想要接入的本地网络，从而可以节约信令资源。该默认的网络为 UE的签约数据中所指示的 UE所远程接入的默认本地网络。当 UE所签约的远程接入网络有多个时，可以随机选择一个，或者预先设定优先级来进行选择。 Optionally, in this embodiment, when the UE initiates the remote access, the PDN connection request may not carry the information of the local network that the UE wants to access. In this case, the MME can regard the default local network as the local network that the UE wants to access, thereby saving signaling resources. The default network is the default local network remotely accessed by the UE indicated in the subscription data of the UE. When there are multiple remote access networks subscribed by the UE, one may be randomly selected, or a priority may be set in advance to select.

图 4是本发明另一实施例的用于远程接入本地网络的方法的流程图。图 4 所示的方法包括如下歩骤：该实施例中，歩骤 401至歩骤 407a与图 3中的歩骤 301至歩骤 307a的相同，在此不再赘述。其中，歩骤 401至歩骤 404在图 4中未示出。 4 is a flow chart of a method for remote access to a local network in accordance with another embodiment of the present invention. The method shown in Figure 4 includes the following steps: In this embodiment, steps 401 to 407a are the same as steps 301 to 307a in FIG. 3, and details are not described herein again. Wherein, steps 401 through 404 are not shown in FIG.

歩骤 407b，在确定 UE允许远程接入第一本地网络的情况下， MME (第一 MME)判断第一本地网络是否由该 MME自身所管辖；如果判断结果为是，即如果第一本地网络是由自身所管辖的，则 MME执行的歩骤同歩骤 307b，由该 MME选择第一本地网关，该第一本地网关为第一本地网络下的本地网关。示例性地，可以根据第一本地网络的信息获得第一本地网关的地址；并且接下来的歩骤同歩骤 308至 312，在此不再赘述；如果判断结果为否，即如果第一本地网络不是由该 MME自身所管辖的，则执行歩骤 408。 Step 407b, in the case that it is determined that the UE allows remote access to the first local network, the MME (first MME) determines whether the first local network is under the jurisdiction of the MME itself; if the determination result is yes, that is, if the first local network If the MME performs the same procedure as the MME, the MME selects the first local gateway, and the first local gateway is the local gateway in the first local network. Illustratively, the address of the first local gateway may be obtained according to the information of the first local network; and the following steps are the same as steps 308 to 312, and details are not described herein; if the determination result is no, that is, if the first local If the network is not under the jurisdiction of the MME itself, then step 408 is performed.

该实施例的具体实现中，可以通过设定本地网络的信息来实现 MME管辖的区分。示例性地，可以在本地网络的信息中包括管辖本网络的 MME的信息。根据该 MME的信息可以判断该第一本地网络是否由当前的 MME自身所管辖。在第一本地网络不是由当前的 MME所管辖时，可以进一歩确定出管辖第一本地网络的第二 MME。 In a specific implementation of this embodiment, the differentiation of the MME jurisdiction can be implemented by setting information of the local network. Illustratively, information governing the MME of the local network may be included in the information of the local network. Based on the information of the MME, it can be determined whether the first local network is governed by the current MME itself. When the first local network is not under the jurisdiction of the current MME, the second MME that governs the first local network can be further determined.

示例性地，以本地网络的信息为本地网络的标识为例来进行说明。该本地网络为可以远程接入的本地网络，示例性地，其标识可以表示为： < 远程网络 ID>₀ 管辖该本地网络的 MME的标识可以作为该本地网络的标识的一部分。示例性地，该 MME的标识可以表示为： <MME 标识符 >。这样，通过本地网络的标识就可以确定该网络与当前的 MME的关系。 Illustratively, the information of the local network is taken as an example of the identifier of the local network. The local network is a local network that can be accessed remotely. Illustratively, its identity can be expressed as: <Remote Network ID> ₀ The identity of the MME that governs the local network can be part of the identity of the local network. Illustratively, the identity of the MME may be expressed as: <MME Identifier>. In this way, the relationship between the network and the current MME can be determined by the identity of the local network.

下面给出 MME 的标识和可以远程接入的本地网络的标识的组成的一个示例。 An example of the composition of the MME and the identity of the identity of the local network that can be accessed remotely is given below.

<MME标识符 > = <MME群 IDxMME码> <MME identifier> = <MME group IDx MME code>

其中 MME标识符表示 MME的标识，其由 MME群标识（MME群 ID) 和 MME码组成。我们可以将远程的本地网络的标识设置成： The MME identifier represents an identifier of the MME, which is composed of an MME group identifier (MME group ID) and an MME code. We can set the identity of the remote local network to:

< 远程网络 ID> = < MME标识符 >< 远程网络码 > <remote network ID> = < MME identifier > < remote network code >

其中远程网络 ID表示远程网络的标识，其由 MME标识符和远程网络码组成。因此通过这样的设置方式就可以通过读取远程网络的标识来判断本地网络与 MME之间的关系。 The remote network ID represents the identity of the remote network, which consists of the MME identifier and the remote network code. Therefore, by such an arrangement, the relationship between the local network and the MME can be judged by reading the identity of the remote network.

歩骤 408，向管辖第一本地网络的第二 MME发送接入通知消息，接入通知消息中包括要接入的第一本地网络的信息，如第一本地网络的标识或名称信息，以指示要接入的本地网络是第一本地网络。示例性地，上述接入通知消息可以是转发接入上下文通知（Forward Access Context Notification)消息。上述对第一本地网络进行指示的信息，可以是第一本地网络的标识或名称。通过该通知消息，第二 MME就知道了 UE想要接入的是哪一个本地网络。 Step 408: Send an access notification message to the second MME that is in the first local network, where the access notification message includes information about the first local network to be accessed, such as the identifier or name of the first local network. Information to indicate that the local network to be accessed is the first local network. Exemplarily, the foregoing access notification message may be a Forward Access Context Notification message. The information indicating the first local network may be an identifier or a name of the first local network. Through the notification message, the second MME knows which local network the UE wants to access.

歩骤 409，第二 MME接收该接入通知消息，根据通知消息中的第一本地网络的信息来选择第一本地网关，得到与第一本地网络对应的第一本地网关的地址。其中，该第一本地网关为第一本地网络下的本地网关。并。 Step 409: The second MME receives the access notification message, and selects the first local gateway according to the information of the first local network in the notification message, to obtain an address of the first local gateway corresponding to the first local network. The first local gateway is a local gateway under the first local network. and.

其中，第二 MME也可以采用上文所描述的多种查询方式来得到第一本地网关的地址，在此不再赘述。 The second MME may also use the multiple query manners described above to obtain the address of the first local gateway, and details are not described herein again.

歩骤 410，第二 MME发送接入确认消息给第一 MME, 该确认消息中包含第一本地网关的地址信息。示例性地，上述接入确认消息可以是转发接入上下文确认 ( Forward Access Context Acknowledge ) 消息。 Step 410: The second MME sends an access confirmation message to the first MME, where the acknowledgement message includes address information of the first local gateway. Exemplarily, the foregoing access acknowledgement message may be a Forward Access Context Acknowledge message.

歩骤 411，第一 MME发送第一创建会话请求给 S-GW, 第一创建会话请求中包含第一本地网关的地址和远程接入指示信息。第一本地网关的地址是从第二 MME所接收的。远程接入指示信息用于指示当前进行的接入为远程接入。第一本地网关的地址可以用于 S-GW与该 L-GW建立连接，而远程接入指示信息可以用于供本地网关进行计费时使用。 Step 411: The first MME sends a first create session request to the S-GW, where the first create session request includes an address of the first local gateway and remote access indication information. The address of the first local gateway is received from the second MME. The remote access indication information is used to indicate that the currently performed access is remote access. The address of the first local gateway may be used by the S-GW to establish a connection with the L-GW, and the remote access indication information may be used for charging by the local gateway.

歩骤 412， S-GW接收第一创建会话请求，并根据第一创建会话请求中的第一网关的地址发送第二创建会话请求给 L-GW,该第二创建会话请求中也保护远程接入指示信息，以指示要进行的是远程接入业务。 Step 412: The S-GW receives the first create session request, and sends a second create session request to the L-GW according to the address of the first gateway in the first create session request, where the second create session request also protects the remote connection The indication information is entered to indicate that the remote access service is to be performed.

歩骤 413，第一本地网关接收第二创建会话请求消息，并根据第二创建会话请求中的远程接入指示信息知道该业务为远程接入业务。然后，可选地，第一本地网关可以生成基于远程接入业务的计费模式，以进行远程接入业务的计费。该计费模式可以与基于本地 IP接入业务的计费模式不同。可选地，第一本地网关还可以基于本地资源的情况，生成远程接入业务的服务质量（QoS， Quality of Service) , 以在资源紧张时可基于不同的业务类型进行优先级处理；例如，该优先级可以是本地接入业务的优先级高于远程接入的优先级。 Step 413: The first local gateway receives the second create session request message, and knows that the service is a remote access service according to the remote access indication information in the second created session request. Then, optionally, the first local gateway may generate a charging mode based on the remote access service for accounting for the remote access service. The charging mode may be different from the charging mode based on the local IP access service. Optionally, the first local gateway may further generate a quality of service (QoS) of the remote access service based on the local resource, so that the priority processing may be performed based on different service types when the resource is tight; for example, The priority may be that the priority of the local access service is higher than the priority of the remote access.

歩骤 414，第一本地网关回复创建会话响应至服务网关，其中创建会话响应中携带所生成的远程接入业务的服务质量，例如 MRA QoS。 Step 414: The first local gateway replies with a create session response to the serving gateway, where the created session response carries the quality of service of the generated remote access service, such as MRA QoS.

歩骤 415，建立无线侧及核心网侧承载，以实现 UE通过第一本地网关建立到第一本地网络的 PDN连接。 Step 415: Establish a radio side and a core network side bearer, so as to implement the UE to establish through the first local gateway. A PDN connection to the first local network.

可选地，在该实施例中， UE发送的 PDN连接请求中可以不携带第一本地网络的信息，例如标识或名称，在该情况下可以根据 UE的签约数据，选择签约的允许远程接入的默认本地网络作为 UE想要接入的第一本地网络来进行连接。 Optionally, in this embodiment, the PDN connection request sent by the UE may not carry the information of the first local network, such as an identifier or a name. In this case, the allowed remote access of the subscription may be selected according to the subscription data of the UE. The default local network is connected as the first local network that the UE wants to access.

图 5为本发明的另一实施例的用于远程接入本地网络的方法的流程图。该实施例与图 3、图 4所示的实施例的不同之处在于，在实施例中， UE 的签约粒度不同。图 3、图 4所示的实施例中， HSS中签约的是允许 UE远程接入的本地网络的信息，例如标识或名称。而该实施例中， HSS中签约的是允许 UE接入的本地网关的地址。该实施例中， MME得到的签约数据至少包括如下信息中的一项：远程接入允许信息，例如 UE的 MRA允许标识；以及允许远程接入的本地网关的地址信息。该实施例通过直接签约本地网关的地址可以简化 MME的接入控制过程。 FIG. 5 is a flowchart of a method for remotely accessing a local network according to another embodiment of the present invention. The difference between this embodiment and the embodiment shown in FIG. 3 and FIG. 4 is that, in the embodiment, the subscription granularity of the UE is different. In the embodiment shown in FIG. 3 and FIG. 4, the HSS subscribes to information of a local network, such as an identifier or a name, that allows the UE to remotely access. In this embodiment, the HSS subscribes to the address of the local gateway that allows the UE to access. In this embodiment, the subscription data obtained by the MME includes at least one of the following information: remote access permission information, such as an MRA permission identifier of the UE; and address information of the local gateway that allows remote access. This embodiment simplifies the access control process of the MME by directly signing the address of the local gateway.

具体地，图 5所示的方法包括如下歩骤： Specifically, the method shown in FIG. 5 includes the following steps:

其中，歩骤 501至歩骤 504与上述歩骤 301至歩骤 304的相同，在此不再赘述。 The steps 501 to 504 are the same as those of the foregoing steps 301 to 304, and are not described herein again.

歩骤 505， UE将第一本地网络的信息发送至服务器，该第一本地网络的信息可以对 UE想要接入的第一本地网络进行指示；该第一本地网络的信息可以是例如网络标识或名称。该服务器能对第一本地网络的信息进行解析，以获得与第一本地网络下的第一本地网关的地址信息。示例性地， UE可以发送名称解析请求至移动网络服务器，该名称解析请求中包含第一本地网络的名称。 Step 505: The UE sends the information of the first local network to the server, where the information of the first local network may indicate the first local network that the UE wants to access; the information of the first local network may be, for example, the network identifier. Or name. The server can parse the information of the first local network to obtain address information of the first local gateway under the first local network. Illustratively, the UE may send a name resolution request to the mobile network server, the name resolution request including the name of the first local network.

示例性地， UE可以通过开放移动联盟（OMA, Open Mobile Alliance) 设备管理（DM, Device Management) 或空中（OTA， Over the Air) 的方式来发送上述待解析的信息。 For example, the UE may send the information to be parsed by means of an Open Mobile Alliance (OMA) device management (DM, Device Management) or an over-the-air (OTA).

歩骤 506，服务器将解析出的第一本地网关的地址信息发送给 UE。 Step 506: The server sends the parsed address information of the first local gateway to the UE.

歩骤 507， UE向 MME发起 PDN连接请求，该 PDN连接请求中包含第一本地网关的地址信息； Step 507: The UE initiates a PDN connection request to the MME, where the PDN connection request includes address information of the first local gateway.

歩骤 508， MME获知 UE请求建立远程 PDN连接。 Step 508: The MME learns that the UE requests to establish a remote PDN connection.

示例性地， MME可以根据第一本地网关的地址与 UE的接入基站的关系来知道 UE是否请求建立远程 PDN连接。具体地，如果 UE的接入基站与第一本地网关的地址所对应的第一本地网关直接连接，则 UE进行的是本地 IP 接入；如果 UE的接入基站与第一本地网关的地址所对应的第一本地网关不是直接连接，则 UE进行的是远程接入，例如可以是 MRA业务。 Exemplarily, the MME may know whether the UE requests to establish a remote PDN connection according to the relationship between the address of the first local gateway and the access base station of the UE. Specifically, if the UE accesses the base station and the first If the first local gateway corresponding to the address of the local gateway is directly connected, the UE performs local IP access; if the access base station of the UE is not directly connected to the first local gateway corresponding to the address of the first local gateway, The UE performs remote access, and may be, for example, an MRA service.

然后， MME可以根据所获得的 UE的签约数据中的远程接入允许信息，获知 UE可以建立 MRA业务的连接，又通过对签约数据中允许接入的本地网关的地址信息与第一本地网关的地址信息进行对比来对接入进行控制。具体地，如果第一本地网关的地址为 UE允许远程接入的本地网关，则允许 UE接入第一本地网关，否则，不允许 UE接入第一本地网关。 Then, the MME may learn, according to the obtained remote access permission information in the subscription data of the UE, that the UE can establish a connection of the MRA service, and obtain the address information of the local gateway that is allowed to access in the subscription data and the first local gateway. The address information is compared to control access.
