    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: The present invention presents a method for small cell communications, comprising: MME transmits a message of setting up a user plane for UE to a base station in a small cell cluster of the UE, wherein the messages of setting up a user plane include information about evolved radio access bearer as well as uplink tunnel identity and address of the transport layer assigned by SGW; the base station assigns downlink TEID and address of the transport layer to the UE, and responds to the MME; the MME transmits the downlink TEID and the address of the transport layer assigned to the UE to the SGW that serves the UE, and receives a response message from the SGW. Examples of the present invention further present an MME device, a base station device, an SGW device and a small cell communication system. The above scheme presented by the present invention provides a method of supporting the architecture and data transmission of small cells, which supports quick handover between small cells, reduces data loss during the handover, avoids multi-hop data forwarding, guarantees QoS, and improves user experience and system performance.

    Abstract: A method for supporting fast recovery of a User Equipment (UE) includes performing, by a serving base station, UE context synchronization for one or more other base stations in a related small cell cluster when a UE accesses the serving base station, performing, by a base station that the UE performs a radio resource control (RRC) connection re-establishment, the RRC connection re-establishment for the UE according to UE context saved in a synchronization process. The present also discloses another method and system for supporting UE fast recovery. By applying the technical solution disclosed by the present disclosure, when the UE moves in a small cell scenario, the UE can be recovered quickly in the case of a failure, so as to avoid the UE returns to an idle mode, avoid data loss, guarantee business continuity, and improve UE experience.

    Abstract: A method and an apparatus for establishing a user plane bearer are provided. The method includes receiving a transport layer address supported by a serving gateway (SGW)/packet gateway (PGW) from a mobile management entity (MME), selecting, by a radio access network (RAN) entity, directly the appropriate transport layer address to establish the user plane bearer, or after receiving the transport layer address transmitted by the SGW/PGW, selecting, by the MME, the appropriate transport layer address to establish the user plane bearer, or reporting, by the MME, the obtained transport layer address used by the access entity to the SGW/PGW to establish the user plane bearer.

    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.
