Abstract: The embodiments of the present invention provide a physical-layer-based handover method. The method includes: generating handover signaling, where the handover signaling carries a signaling type identifier and a destination identifier that are used for handover, and the handover signaling is an HS-SCCH order or specific HS-SCCH signaling; and sending the handover signaling to a physical layer of a mobile terminal, so that the mobile terminal executes handover according to the handover signaling to be handed over to a small cell indicated by the destination identifier. A handover method based on a network side physical layer and a mobile terminal physical layer is provided, and even if cell IDs of a macro cell and a small cell or those of small cells are the same, handover of the mobile terminal can be implemented.

Abstract: A method, an apparatus, and a system for detecting a radio network problem are disclosed. The method includes: when a radio network problem occurs on a user equipment (UE), a first base station controlling a cell that a radio resource control (RRC) connection established with the UE, receives problem information about the radio network problem sent by the UE, in a procedure of re-establishing the RRC connection by the UE, and sends the problem information to a second base station controlling a cell where the radio network problem occurs.

Abstract: A system, base station and method are disclosed for detecting a radio network problem. For a handover failure occurs on a user equipment (UE), a first base station receives, problem information about the occurred handover failure from the UE, after a radio resource control (RRC) connection is reestablished or established between the UE and a cell controlled by the first base station. The first base station then transmits the received problem information to a second base station controlling a cell where the handover failure occurs. In this way, the network side can automatically identify and detect the handover failure. As such, the network can perform self-adjustment and optimization, therefore improving the network performance and satisfying use requirements of users.

Abstract: The embodiment of the present disclosure provided a method, device, and system for processing a message. The method for processing a message comprises obtaining a traffic type of a service data packet, sending the message or a data packet that carries the traffic type to a radio network controller, where the radio network controller obtains the traffic type and performs scheduling processing on the service data packet according to a quality of service requirement corresponding to the traffic type. The present disclosure can realize performing resource allocation and scheduling processing on the applications corresponding to the service data packet based on the traffic type. Compared to resource allocation and scheduling processing based on the traffic type in the prior art, the granularity of classification of the present disclosure is more refined, and can realize more refined resource allocation and scheduling processing, and can effectively improve the efficiency of scheduling processing.

Abstract: A method for forwarding downlink packets based on S1 handover is provided. The method includes: numbering a packet not processed by using PDCP according to a message that comprises PDCP Serial Number (SN) information if downlink packets to be forwarded include the packet not processed by using PDCP; and sending the downlink packets to the UE according to the PDCP SN corresponding to the packet included in the downlink packets. A method for forwarding uplink packets based on S1 handover is disclosed. The method includes: receiving state report information of the packet sent by the target eNodeB; and sending the packet according to the state report information of the packet. Another method for forwarding downlink packets based on S1 handover and an eNodeB are disclosed. Through the embodiments of the present disclosure, the packets are forwarded without loss in the case of S1 handover.

Abstract: A method and an apparatus for non-access stratum (NAS) message processing during handover in an evolved network are provided. The method includes the following steps. An evolved packet core (EPC) receives a message which indicates that a UE is being handed over sent by a source evolved NodeB (S-eNB), and stops sending an NAS message to the UE temporarily. The EPC receives a message which indicates that the UE returns to an S-eNB service area sent by the S-eNB. The EPC sends the NAS message to the UE through the S-eNB, if needed. With the method and the apparatus, the EPC can acquire a location of the UE in time in the case of a handover failure of the UE, a time limit of a retransmission timer is set precisely, and a specific implementation for forwarding an NAS message through an X2 interface is provided.
