A 5G or pre-5G communication system is provided to support higher data transmission rates after 4G communication systems such as LTE. To support communication of a terminal that dually accesses a first radio access technology (RAT) communication system and a second RAT communication system, a session generation request message for transmitting traffic is received from a terminal. A target communication system that is to generate a data path with respect to the traffic from the first RAT communication system and the second RAT communication system is determined, the data path for the target communication system is configured, and information about the configured data path is transmitted to the terminal.

A method and an apparatus for synchronizing communication between nodes in a bluetooth low energy (BLE) mesh network. In the network, a node is configured to generates a seed value based on at least one of own transmission parameter, wherein the seed value indicates next data advertisement instance of corresponding node. Further, the seed value is used for communicating with other nodes (i.e. 1-hop neighbor nodes) in the network. Based on data transfer requirements of the node, the node synchronizes own data transmission and reception settings, such that no two nodes transmit data at the same time.

A handover method in a mobile CCN. In the method, when detecting a UE performing a handover, a source local CCNx node caches data directed to the UE. The source local CCNx node transmits a request to stop transmission of the data directed to the UE to a target local CCNx node based on a condition. The target local CCNx node requests the source local CCNx node to stop transmission of contents that are being cached. The source local CCNx node transmits cached contents to the target local CCNx node. The target local CCNx node requests a CCNx entry node to stop transmission of specific contents based on a condition. The CCNx entry node transmits contents to the target local CCNx node. When detecting, the UE completing the handover, the target local CCNx node transmits the contents received from the CCNx entry node to the UE.
