Abstract: Disclosed are a method and apparatus for implementing traffic splitting. The method includes: after a control plane function obtains an application identifier, a packet flow description corresponding to the application identifier and location information applicable to the packet flow description from an application, the control plane function provides the packet flow description to a user plane function corresponding to the location information applicable to the packet flow description, so that the user plane function splits traffic data corresponding to the application identifier. In the solutions of the embodiments of the present disclosure, the packet flow description is installed on the corresponding user plane function by using the location information, and thus the traffic splitting is implemented.

Abstract: The present document provides a method, a device and a system for implementing a local gateway service. Wherein the method includes: adding, by a first connection device, a second connection device for a terminal (300); interacting collocated local gateway address information between the first connection device and the second connection device (301); and reporting, by the first connection device, determined collocated local gateway address information to a core network, and using, by the core network, the collocated local gateway address information to perform the local gateway service (302). Through the technical solution provided by the embodiment of the present document, the core network obtains the collocated local gateway address information, and the local gateway service is implemented aiming at a dual-connection service scenario.

Abstract: Methods and devices for notifying an authorization update are provided. In a method for notifying an authorization update, a home network Proximity-based Services (ProSe) functional entity of an announcing terminal receives a notification message from a ProSe application server, where the notification message is used for notifying the home network ProSe functional entity of the announcing terminal that authorization information changes (S302); and the home network ProSe functional entity of the announcing terminal notifies a home network ProSe functional entity of a monitoring terminal that a ProSe code and/or filter corresponding to the announcing terminal become/becomes invalid or are/is updated (S304).

Abstract: Provided are a cross-Master eNB (MeNB) switching method and apparatus, and a base station. The method comprises: a target MeNB determines that a UE has already established a selected internet protocol traffic offload (SIPTO)/local internet protocol access (LIPA) service on a secondary eNB (SeNB) before the switching; and the target MeNB retains or releases the SIPTO/LIPA service, wherein the user equipment (UE) is accessed to a source MeNB and the SeNB through dual links before the switching, and the UE is accessed to the target MeNB and the SeNB through the dual links after the switching, and a combined local gateway (L-GW) supporting the SIPTO/LIPA service is configured on the SeNB. By means of the present invention, the problem in the related art of not considering the processing of the SIPTO/LIPA service in the cross MeNB switching process is solved, thereby providing an SIPTO/LIPA service processing method in the cross MeNB switching process.
