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 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.

Abstract: A service recovery method and a device for a wireless communication network are disclosed. In an embodiment, the method includes receiving, by a target base station, a radio resource control (RRC) re-establishment request from a terminal and sending, by the target base station, an indication message indicating a radio link failure to a source base station to trigger the source base station with self-determination to initiate a handover preparation procedure between the source base station and the target base station, wherein the terminal remains in an active state.

Abstract: A method for forwarding downlink packets based on S1 handover is disclosed. 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 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.
