图 2示出了根据本发明实施例的用于触发用户设备的方法 100的示意性 流程图。 如图 2所示， 该方法 100包括： FIG. 2 shows a schematic flowchart of a method 100 for triggering user equipment according to an embodiment of the present invention. As shown in FIG. 2, the method 100 includes:

S110, 向用户设备发送非接入层（Non-Access Stratum, 简称为 "NAS" ) 消息， 该 NAS消息携带用于服务器与该用户设备通信的触发地址； S110. Send a Non-Access Stratum (Non-Access Stratum, "NAS" for short) message to the user equipment, where the NAS message carries a trigger address for communication between the server and the user equipment;

S120, 接收该服务器发送的目的 IP地址为该触发地址的触发消息； S130, 通过 SGW将该触发消息发送给该用户设备， 以便于该用户设备 根据该触发消息， 建立与该服务器的通信连接。 S120. Receive a trigger message sent by the server whose destination IP address is the trigger address; S130. Send the trigger message to the user equipment through the SGW, so that the user equipment can establish a communication connection with the server according to the trigger message.

为了实现服务器触发用户设备 UE启动与该服务器的通信， 分组数据网 络网关 PGW可以首先向 UE发送携带触发地址的 NAS消息，以将该触发地 址配置给 UE。 PGW在接收到服务器发送的目的 IP地址为该触发地址的触 发消息后， 通过服务网关 SGW将该触发消息发送给 UE, 以便于该 UE能够 根据该触发消息建立与该服务器的通信连接。 In order to realize that the server triggers the user equipment UE to start communication with the server, the packet data network gateway PGW may first send a NAS message carrying a trigger address to the UE, so as to configure the trigger address to the UE. After receiving the trigger message sent by the server with the destination IP address being the trigger address, the PGW sends the trigger message to the UE through the serving gateway SGW, so that the UE can establish a communication connection with the server according to the trigger message.

本发明实施例的方法， 通过为用户设备、 分组数据网络网关和服务器配 置用于服务器与用户设备通信的触发地址，使得当服务器需要触发用户设备 进行通信时， 只需向该触发地址发送触发消息就可以实现对该用户设备的触 发， 避免了相关技术中需要网络向外部提供控制平面的接口， 因而能够减小 对网络的改动， 并具有简单易操作的优点。 In the method of the embodiment of the present invention, by configuring the user equipment, the packet data network gateway, and the serverSet the trigger address for communication between the server and the user equipment, so that when the server needs to trigger the user equipment to communicate, it only needs to send a trigger message to the trigger address to trigger the user equipment, which avoids the need for network communication in related technologies. The interface of the control plane is provided externally, so that changes to the network can be reduced, and it has the advantage of being simple and easy to operate.

在本发明实施例中， 当 UE附着到网络时， PGW可以通过向 UE发送 In this embodiment of the present invention, when the UE is attached to the network, the PGW may send the UE

NAS消息的方式， 将触发地址配置给 UE, 此时该 NAS消息除携带 UE通常 的 IP地址之外， 还需要携带用于服务器与 UE通信的该触发地址。 应理解， 该 NAS消息携带的 UE的 IP地址通常是动态变化的，该 IP地址用于网元基 于控制平面与该 UE进行通信； 而该 NAS消息携带的触发地址通常是静态 配置的， 用于服务器基于数据平面与该 UE进行通信。In the NAS message mode, the trigger address is configured to the UE. At this time, the NAS message needs to carry the trigger address used for communication between the server and the UE in addition to the usual IP address of the UE. It should be understood that the IP address of the UE carried in the NAS message usually changes dynamically, and the IP address is used by the network element to communicate with the UE based on the control plane; and the trigger address carried in the NAS message is usually statically configured for The server communicates with the UE based on the data plane.

应理解， 在本发明实施例中， 触发地址还需要配置给 PGW和服务器。 例如将该触发地址作为 UE所属组的属性之一， 静态配置到 PGW上， 将该 触发地址作为 UE或 UE所属组的属性之一， 静态配置到服务器上， 当服务 器需要触发 UE进行通信时， 服务器只需要向该触发地址发送触发消息就可 以实现对该 UE的触发。 It should be understood that in the embodiment of the present invention, the trigger address also needs to be configured for the PGW and the server. For example, the trigger address is statically configured on the PGW as one of the attributes of the group to which the UE belongs, and is statically configured on the server as one of the attributes of the UE or the group to which the UE belongs. When the server needs to trigger the UE to communicate, The server only needs to send a trigger message to the trigger address to trigger the UE.

在本发明实施例中， 可以为属于同一个组的 UE分配一个相同的用于服 务器与用户设备通信的触发地址。 例如， 使用接入点 ( Access Point Name, 简称为 "APN" )来标示一个 UE组 ,即该 UE组中的 UE都属于同一个 APN, 并为该 UE组分配一个用于服务器与用户设备通信的触发地址， 该触发地址 例如可以是 IP@APN。 该触发地址可以作为该 APN的属性之一配置到与该 APN所对应的 PGW上， 或作为 UE或 UE组的属性之一配置到服务器上， 用于 UE或 UE组的触发。 可选地， 该触发地址用于服务器与属于同一接入 点 APN的用户设备通信。 下文中将主要以使用 APN标示 UE组为例进行说 明， 应理解， 这仅仅是为了示例， 不应对本发明构成任何限定。 In the embodiment of the present invention, UEs belonging to the same group may be assigned the same trigger address for communication between the server and the user equipment. For example, an access point (Access Point Name, "APN" for short) is used to mark a UE group, that is, the UEs in the UE group all belong to the same APN, and the UE group is assigned an The trigger address of , for example, the trigger address may be IP@APN. The trigger address can be configured on the PGW corresponding to the APN as one of the attributes of the APN, or configured on the server as one of the attributes of the UE or UE group, and is used for triggering of the UE or UE group. Optionally, the trigger address is used for the server to communicate with user equipment belonging to the same access point APN. The following will mainly use the APN to mark the UE group as an example for illustration. It should be understood that this is only for example and should not constitute any limitation to the present invention.

在本发明实施例中， 该触发地址是 IP地址， 可选地， 该触发地址可以 是单播地址或组播地址。 不论该触发地址是单播地址还是组播地址， 该触发 地址都应该保证目的地址为该触发地址的数据能够从服务器正确路由到与 该触发地址对应的 PGW。 In the embodiment of the present invention, the trigger address is an IP address, and optionally, the trigger address may be a unicast address or a multicast address. Regardless of whether the trigger address is a unicast address or a multicast address, the trigger address should ensure that the data whose destination address is the trigger address can be correctly routed from the server to the PGW corresponding to the trigger address.

在本发明实施例中， 当服务器需要触发某个 APN的所有 UE、 部分 UE 或者某个 UE时，可以通过向与该 UE对应的触发地址发送触发消息来实现。 该触发消息会首先到达所属路由域的 PGW, 然后 PGW可以使用不同的方 法， 通过 SGW将该触发消息发送给 UE。 在本发明的某些实施例中， PGW 需要将该触发消息中包括的触发指示进一步传递到 MME, 从而 MME能够 根据所收到的触发指示， 使用寻呼消息 （Paging )对相关的 UE——进行寻 呼。 由此， UE 能够在接收到该触发消息后， 根据该触发消息建立与服务器 的通信连接。 In the embodiment of the present invention, when the server needs to trigger all UEs, some UEs or a certain UE of a certain APN, it can be realized by sending a trigger message to the trigger address corresponding to the UE. The trigger message will first reach the PGW of the routing domain, and then the PGW can use different methodsIn this way, the SGW sends the trigger message to the UE. In some embodiments of the present invention, the PGW needs to further transmit the trigger indication included in the trigger message to the MME, so that the MME can use a paging message (Paging) to the relevant UE according to the received trigger indication—— to page. Therefore, after receiving the trigger message, the UE can establish a communication connection with the server according to the trigger message.

应理解， UE在接收到触发消息后， 可能与服务器建立通信连接， 也可 能由于各种原因不与服务器建立通信连接， 例如 UE 出现异常状态， 或该 UE并不属于服务器触发的 UE之一等。 因而， 在本发明实施例中， 收到服 务器发送的触发消息的 PGW将该触发消息发送给 UE,以便于 UE能够建立 与该服务器的通信连接， 但是并不限定所有的 UE—定与服务器建立通信连 接， 本发明实施例并不限于此。 It should be understood that after receiving the trigger message, the UE may establish a communication connection with the server, or may not establish a communication connection with the server due to various reasons, for example, the UE is in an abnormal state, or the UE is not one of the UEs triggered by the server, etc. . Therefore, in the embodiment of the present invention, the PGW that receives the trigger message sent by the server sends the trigger message to the UE, so that the UE can establish a communication connection with the server, but it is not limited that all UEs must establish a communication connection with the server. The communication connection is not limited in this embodiment of the present invention.

下面将结合图 3至图 6, 分别描述 PGW通过不同的方法将触发消息发 送给 UE。 The PGW sends the trigger message to the UE through different methods in combination with FIG. 3 to FIG. 6 below.

图 3 示出了用于触发用户设备的方法 200 的具体实施例的示意性流程 图。 如图 3所示， 该方法 200包括： Fig. 3 shows a schematic flowchart of a specific embodiment of a method 200 for triggering user equipment. As shown in FIG. 3, the method 200 includes:

5201 ,在 UE附着到网络的流程中， PGW向 UE发送 NAS消息，该 NAS 消息携带用于服务器与该 UE通信的触发地址。 在此过程中， 如果 PGW上 已经为该 UE所请求的 APN配置了触发地址， 该触发地址用于服务器与属 于该 UE需要建立连接的 APN的一个或多个用户设备通信，那么除去 UE通 常的 IP地址以外， PGW还将返回该触发地址给该 UE, 该触发地址例如为 IP@APN,下文中将以 IP@APN为例进行说明。然后， PGW将为该 IP@APN 建立与该 IP@APN相关的 UE的列表 , 即 IP@APN UE列表。 5201. During the process in which the UE attaches to the network, the PGW sends a NAS message to the UE, where the NAS message carries a trigger address for communication between the server and the UE. During this process, if the trigger address has been configured on the PGW for the APN requested by the UE, and the trigger address is used for the server to communicate with one or more user equipments belonging to the APN that the UE needs to establish a connection with, then the usual In addition to the IP address, the PGW will also return the trigger address to the UE. The trigger address is, for example, IP@APN, and IP@APN will be used as an example for illustration below. Then, the PGW will establish a list of UEs related to the IP@APN for the IP@APN, that is, an IP@APN UE list.

5202, 服务器发送目的 IP地址为该触发地址的触发消息。 具体地， 服 务器需要触发配置了触发地址的 UE时， 只需要向为该 UE分配的触发地址 发送触发消息即可。 5202. The server sends a trigger message whose destination IP address is the trigger address. Specifically, when the server needs to trigger the UE configured with the trigger address, it only needs to send a trigger message to the trigger address allocated for the UE.

5203 , PGW根据该触发地址与用户设备的对应关系， 将该触发消息通 过与该触发地址对应的每个用户设备的 SGW和 PGW之间的承载， 将该触 发消息发送给该每个用户设备的 SGW。 具体地， 当 PGW接收到发送到 IP@APN的触发消息后， 根据 IP@APN UE列表， 将接收到的该触发消息进 行拷贝， 并使用到与该 IP@APN UE列表里相应的所有 UE的承载将其发送 到与这些 UE对应的 SGW。 5204 , 与该用户设备对应的该 SGW通过该承载接收到该触发消息后， 在确定该用户设备处于空闲状态时，通过向与该用户设备对应的移动性管理 实体 ΜΜΕ发送下行数据到达消息， 以触发该 ΜΜΕ发起对该用户设备的寻 呼。 即当 SGW接收到触发消息以后，如果与该 SGW对应的 UE处于空闲状 态， 则向 ΜΜΕ发送下行数据到达消息， 触发 ΜΜΕ发起对该 UE的寻呼。 5203. According to the correspondence between the trigger address and the user equipment, the PGW sends the trigger message to each user equipment's SGW. Specifically, after the PGW receives the trigger message sent to the IP@APN, it copies the received trigger message according to the IP@APN UE list, and uses all UEs corresponding to the IP@APN UE list The bearer sends it to the SGW corresponding to these UEs. 5204. After receiving the trigger message through the bearer, the SGW corresponding to the user equipment sends a downlink data arrival message to a mobility management entity MME corresponding to the user equipment when determining that the user equipment is in an idle state, to Triggering the MME to initiate paging for the user equipment. That is, after the SGW receives the trigger message, if the UE corresponding to the SGW is in an idle state, it sends a downlink data arrival message to the MME, and triggers the MME to initiate paging of the UE.

5205 , ΜΜΕ接收到 SGW发送的下行数据到达消息后， 向 RAN发送寻 呼消息， 以用于指示 UE建立与网络的连接。 5205. After receiving the downlink data arrival message sent by the SGW, the MME sends a paging message to the RAN to instruct the UE to establish a connection with the network.

5206 , RAN向 UE发送寻呼消息， 用于指示 UE建立与网络的连接。 5206. The RAN sends a paging message to the UE, which is used to instruct the UE to establish a connection with the network.

5207, UE接收到寻呼消息后重新与网络建立连接。5207. After receiving the paging message, the UE re-establishes a connection with the network.
