摘要： Embodiments of the present disclosure provide a data packet sending method and apparatus, and relate to communications field. The method includes: receiving, by an SGW-U, a data packet, and matching context information of a corresponding bearer according to a tunnel endpoint identifier (TEID) carried in the data packet; sending a trigger message to a serving gateway for control plane SGW-C if the SGW-U determines, through matching, that the SGW-U does not include the context information of the bearer, where the trigger message carries the TEID, and the trigger message is used by the SGW-C to obtain the context information of the bearer according to the TEID; receiving a reestablish bearer context message sent by the SGW-C, where the reestablish bearer context message carries the context information of the bearer; and sending the data packet according to the context information of the bearer.

摘要： The present disclosure relates to a user data processing apparatus and method, and a system. In the user data processing apparatus disclosure, an interface management unit receives user data; at least two service units process the user data, where the at least two service units include a session unit and at least one of a bearer unit, a service flow unit, or a content unit; the interface management unit determines the session unit configured to process the user data, and sends the received user data to the determined session unit; and the session unit determines another service unit configured to process the user data. After receiving the user data, the GW-U determines the service unit configured to process the user data, and processes the user data by using the service unit determined by the GW-U. This improves processing flexibility of the GW-U.

摘要： An embodiment of the present invention provides a method for establishing a Gs association, where the method includes: when a serving GPRS support node SGSN determines that an SGs association of a user equipment UE in an idle mode signaling reduction function ISR activated state is released, sending, by the SGSN, a location update request to a mobile switch center/visitor location register MSC/VLR, so that the SGSN and the MSC/VLR establish a Gs association for the UE. An embodiment of the present invention further provides an SGSN. In the embodiments of the present invention, when a UE is in an ISR activated state, and after an SGs association is released, a Gs association can be established in time, and therefore, the UE is not implicitly detached by an MSC/VLR, and a mobile terminated service of the UE is not affected, thereby enhancing service experience of a user.
摘要翻译： 本发明的一个实施例提供了一种建立Gs关联的方法，其中该方法包括：当服务GPRS支持节点SGSN确定消息中处于空闲模式信令减少功能ISR激活状态的用户设备UE的SGs关联时， 由SGSN向移动交换机中心/访问者位置寄存器MSC / VLR发送位置更新请求，使得SGSN和MSC / VLR为UE建立Gs关联。 本发明的实施例还提供了一种SGSN。 在本发明的实施例中，当UE处于ISR激活状态，并且在SGs关联被释放之后，可以及时建立Gs关联，因此UE不会被MSC / VLR隐含地分离， 并且UE的移动终端服务不受影响，从而增强用户的服务体验。
