Abstract: The present disclosure provides a method and device for configuring a node to transmit and receive data. A second node receives a first message by a first node, wherein the first message comprises at least one of information for determining a channel used by the second node to transmit data received by the second node, or information for determining a radio bearer to transmit data received. Also, the second node transmits the received data mapped to at least one of the channel or the radio bearer used to transmit the data. Through the above method and device, mapping between the received data and transmitted data of each node in a multi-hop network is realized

Abstract: A communication method and system are provided for converging a 5G communication system with technology for IoT. The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a V2X includes receiving, from a terminal, a V2X message including location information on the terminal; determining a first MBMS broadcast area for a V2X service based on the location information on the terminal; transmitting, to a BMSC, a first request message for the V2X service including information on the first MBMS broadcast area and a first TMGI for the V2X service, wherein the information on the first MBMS broadcast area includes at least one MBMS SAI mapped to the location information on the terminal; and transmitting, to the BMSC, a second request message for the V2X service, the second request message including information on a second MBMS broadcast area for broadcasting second MBMS data for the V2X service and the first TMGI. The first MBMS data is broadcast within the first MBMS broadcast area, and the first TMGI is used for the second MBMS data, in case that the first MBMS broadcast area does not overlap the second MBMS broadcast area.

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: 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.

Abstract: The present application discloses a method for configuring and transmitting a key, which includes that: a) a serving cell (PCell) of UE determines a key (KeNB) used by a SCell and transmits the KeNB to the SCell; and b) the PCell transmits configuration information for configuring the SCell to the UE after receiving a response message from the SCell, and receives a response message from the UE. Or, the method includes that: a SCell of UE transmits a cell key request to an MME and receives key information from the MME; and the SCell transmits the key information received from the MME to the UE, and receives a response message from the UE. By the present application, data of the SCell is transmitted after being encrypted, so as to avoid a case that the data is decoded by other users, and further guarantee the security of the data.
