Communications system, base station apparatus, and communication method for dual-mode femtocells

摘要

In a communication system (1) for dual-mode femtocells, an upper-level carrier (10) has communication functions for both first and second sessions. A first communication unit (21) communicates with the upper-level carrier (10) through a first communication session established therewith. A second communication unit (22) communicates with the upper-level carrier through a second communication session established therewith. A communication control unit (23) controls the first and second communication units. The communication control unit (23) 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 (10) by using the second communication session as a detour.
