Abstract: Provided is a data packet transmission method and device. The method includes: generating, by a first network element, first indication information according to a delivery status fed back by a second network element to the first network element, where the first indication information is used for instructing the second network element which has not successfully sent a data packet to a terminal to discard the data packet indicated by the first indication information. The present disclosure may solve the problem in the related art of unsynchronized data transmission in sending of a data packet to a terminal by a plurality of second network elements.

Abstract: A method and apparatus are described for adaptive interference discovery of a licensed shared access (LSA) system. The method includes: an LSA controller selects a measurement node according to interference protection information of an LSA licensed system; the LSA controller sends a measurement configuration message to the measurement node; and the LSA controller receives a measurement response message returned by the measurement node and determines whether to perform LSA spectrum resource reconfiguration according to the measurement response message.

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.

Abstract: The present disclosure discloses a method and apparatus for processing information. The method for processing information comprises: retrieving, by a first base station, user context information of a User Equipment (UE) from a second base station by initiating a procedure to the second base station for retrieving the user context information, wherein the user context information doesn't include user history information; updating, by the first base station, bearer path information and resuming the user context information by initiating a path switch request message to a device in a core network; and performing, by the first base station, one or more of the following operations after the UE resumes to a connected state: re-starting to collect user history information, and re-retrieving user history information from the UE through an air interface.

Abstract: A method and a base station for processing an SIPTO (Selected IP Traffic Offload) connection, the method includes: when a terminal is handed over from a source SeNB (Secondary eNB) to a destination SeNB, receiving, by an MeNB (Master eNB), an interface message from the destination SeNB (11), herein the source SeNB supports a collocated L-GW (Local Gateway); and when a handover success acknowledgement message sent by the destination SeNB is received, triggering, by the MeNB, the source SeNB to notify the L-GW to release an SIPTO@LN (Selected IP Traffic Offload at Local Network) connection (12). Through the embodiments of the present document, the release of the SIPTO@LN connection in a collocated L-GW scenario under a small base station environment can be effectively implemented.
