    Abstract: An embodiment of the present disclosure may provide an inter-MeNB handover method in a small cell system, including: making, by a source MeNB and/or target MeNB, a determination as to whether to maintain a SeNB when handover is performed; and triggering different handover processes according to a result of the determination as to whether to maintain the SeNB. Another embodiment of the present disclosure may further provide an inter-MeNB handover device in a small cell system. With the inter-MeNB handover method and device in a small cell system provided by the present disclosure, unnecessary deletion and re-establishment of the bearers at the SeNB for the UE may be reduced. False bearer deletion may be avoided and data forwarding may be reduced. Furthermore, the SeNB may be maintained according to network deployment and SGW re-selection may be supported. Therefore, system capacity and transmission speed of the data may be improved.

    Abstract: The present invention discloses a method for detecting a cause for a Radio Link Failure (RLF) or handover failure is provided. The method includes when a User Equipment (UE) enters a connection mode after encountering RLF or handover failure, sending a RLF report that the UE encounters RLF or handover failure to a base station; determining, by the base station, a cause for RLF or handover failure according to the RLF report, if it is determined that the cause for RLF or handover failure is a problem of Mobility Robustness Optimization (MRO) or a problem of coverage, when it is a problem of MRO, sending, by the base station, a MRO report to a base station at which a cell which triggers handover for the last time is located.

    Abstract: The present application discloses a method for enabling a user equipment to access a radio network, a network equipment and a user equipment. A specific embodiment of the method comprises: determining, by a network equipment, whether a predetermined condition is satisfied; and if yes, the method further comprises: transmitting, by the network equipment, information indicating whether a radio network to which the network equipment belongs is isolated, such that the user equipment performs related operations. In the embodiment, the network equipment informs UE of state information about whether the radio network to which network equipments belongs is isolated or not in different ways, so that the isolated network can provide users with reliable local bearer supporting service continuity, thereby meeting communication requirements for public safety and the like.

    Abstract: Various examples provide a method for radio resources management. An MCE or a GCSE AS or a UE receives usage information of eMBMS radio resources, and adjusts radio resources in response to a determination that there is an overload state. The MCE may re-configure the eMBMS radio resources. Alternatively, the UE or the GCSE AS may establish a unicast channel for transporting a GCSE service which was transmitted on an overloaded eMBMS bearer, and release the eMBMS bearer. The technical mechanism can make effective use of radio interface resources and reduce data loss.
