Abstract: A method includes: receiving, by a network element selector, a first message from a first external network element, where the first message carries a first session index, and the first session index is used to identify UE served by the first external network element; and sending, by the network element selector, the first message to a first converged controller based on mapping information corresponding to the UE and the first session index in the first message, where the mapping information includes a mapping relationship between the first converged controller and a plurality of different session indexes of the UE, and the plurality of different session indexes of the UE include the first session index. It can be learned that the network element selector sends, based on the mapping information corresponding to the UE, all messages of different external network elements serving the UE to a same converged controller.

Abstract: A method for reporting radio bearer loss information is provided in an embodiment of this invention. The method comprises: receiving a User Equipment UE Context Release Request message or a Release Access Bearer Request message or an Iu interface release request message all carrying a release cause value; and if the release cause value indicates an abnormal release, reporting radio bearer loss information to a gateway while preserving non-GBR bearers. With the method and apparatus of embodiments of this invention, not only bearer reporting can be realized, but also problems caused by the release of Non-Guaranteed Bandwidth non-GBR bearers can be prevented.

Abstract: A method for displaying a graphical user interface (GUI) is disclosed, which relate to the data processing field. The method specifically includes: determining whether a display of a device is shielded; when it is determined that the display is shielded, determining a shielded area and a display area of the display; determining parameter information of the display area, where the parameter information includes an area size of the display area and a position of the display area; and obtaining, according to the parameter information, a GUI that matches the display area, and displaying the GUI in the display area. Whether a display of the device is shielded is determined. When the display is shielded, the GUI is displayed in the display area, so that the GUI can be displayed only in the display area of the display and does not need to be displayed in full screen.
