  • Patent number: 8892089
    Abstract: In a communication system, an upper-level carrier has communication functions for both first and second sessions. A first communication unit communicates with the upper-level carrier through a first communication session established therewith. A second communication unit communicates with the upper-level carrier through a second communication session established therewith. A communication control unit controls the first and second communication units. The communication control unit disconnects the first communication session and directs a signal intended for the first communication session to the second communication session, so that the signal is delivered to the upper-level carrier by using the second communication session as a detour.

  • Publication number: 20140080486
    Abstract: A wireless communications system includes a SeGW, a femto base station, and a macro base station. The SeGW is coupled to a higher-level station. The femto base station is coupled to the SeGW through a wired broadband connection. The macro base station is coupled to the SeGW through a dedicated line. The femto base station measures the quality of the wired broadband connection using first time information and second time information when a mobile station performs a handover from the macro base station to the femto base station. The first time information represents the time when data forwarded from the macro base station to the femto base station is transmitted. The second time information represents the time when the data is received.
