A mobile wireless system includes a first gateway (L-PGW), a second gateway (PGW), a first access point (HeNB) capable of establishing a communication path simultaneously with the first and second gateways, and a second access point (eNB) capable of establishing a communication path only with the PGW. When a mobile terminal connected to the HeNB and communicating with a communication destination node using a first path through the L-PGW switches a connection destination to the eNB, the HeNB establishes a second path through the HeNB and the PGW, while maintaining the first path. The HeNB transmits data, which has been transmitted to the HeNB along the first path, to the eNB along the second path, until the UE is connected to the eNB, and a third path to the communication destination node through the PGW is established. Accordingly, an interruption time of data reception involved in handover is shortened.
