Abstract: 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.
Abstract translation: 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。

Abstract: The present disclosure relates to a QoS guarantee method. In one example method, a control plane gateway obtains a QoS parameter. The QoS parameter comprises an allocation/retention priority (ARP) and a QoS class identifier (QCI). The control plane gateway maps the QoS parameter to QoS guarantee information. The QoS guarantee information comprises a differentiated services code point (DSCP) parameter. The control plane gateway sends the QoS guarantee information to a user plane gateway. The QoS guarantee information is to be used by the user plane gateway for QoS marking.
