    摘要: A method enabling an relay node (RN) to support multiple wireless access techniques is provided, which includes: a mobility management element (MME) requests a DeNB to establish evolved radio access bearers (ERAB) of EUTRAN and indicates access network information that will be transmitted by each of the ERABs; the DeNB requests an RN to establish radio bearers (RB) and indicates the access network information that will be transmitted by each of the RBs. The above method makes fewer modifications to conventional networks and techniques, guarantees service quality provided for a UE accessing an LTE system, and enables an RN to support access of UEs using multiple access techniques.

    摘要: Examples of the present disclosure provide a method for determining access control, applied in a handoff procedure of a UE. The method include receiving, from a source base station, a first message including a first local home network (LHN) identifier (ID) and an address of a local gateway; receiving, from a target base station, a second message including a second LHN ID; determining whether a LHN ID is changed based on the first LHN ID and a second LHN ID; and disconnecting a selected IP traffic offload (SIPTO) service if the LHN ID is changed. According to a technical solution provided by the present disclosure, service continuity of the LIPA service or the SIPTO service can be maintained correctly.

    摘要: A method for supporting indication of a failure event to a source access system is provided. The method includes notifying, by the source access system, information of a source cell to a target access system, routing, by the target access system, a message to the base station or the base station controller of the source access through a core network by use of the information of the source cell received from the source access system when the target access system needs to transmit a message to the source access system. By use of the method provided by the present disclosure, a problem of mobility robustness optimization (MRO) among different radio access technology (RAT) may be notified to the source access system, so as to avoid impact for a terminal, reduce operator configuration.

    摘要: A method and a system for processing a Radio Link Failure (RLF) report, where when a User Equipment (UE) encounters an RLF in a first cell controlled by a first evolved base station and selects a second cell controlled by a second evolved base station to re-establish an Radio Resource Connection (RRC), are provided. The method includes sending, by the second evolved base station, the RLF report to every corresponding evolved base station according to the PCI of the first cell having been received from the UE, where the PCI of the first cell, the PCI of a second cell, the CRNTI of the UE in the first cell, and UE authentication information are carried in the RLF report, and authenticating, by every evolved base station the UE according to the UE authentication information. Another method for processing an RLF report, and two methods for adjusting a mobile parameter, are also provided.

    摘要: A method for detecting a cause of radio link failure (RLF) or handover failure, in which the first base station triggers a handover process for the UE, and the mobility or handover information of the UE in the source cell is sent to a second base station. After the second base station receives the RLF report of the UE, the second base station can determine cause of a failure according to the RLF report of the UE and the mobility or handover information of the UE in the source cell. Other methods detect a cause of radio link failure (RLF) or handover failure. Application of the methods can improve the accuracy of determining the cause of the RLF or handover failure, improve efficiency of MRO and improve system performance.

    摘要: 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.
