Patent ID: 8588790

Claim:
A handover method of a Mobile Station (MS) in a wireless communication system in which at least one small cell resides in a macro cell, the method comprising: checking a movement speed of the MS in response to entering a neighboring small cell; determining whether to hand over to the small cell by taking into account the movement speed of the MS; transmitting small cell penetration information to a macro Base Station (BS), when determining not to hand over to the small cell, wherein the transmitting of the small cell penetration information to the macro BS comprises: handing over to the macro BS, when the macro BS is not a serving station; and transmitting small cell penetration information to the macro BS; communicating with the macro BS in the small cell using a macro only resource allocated from the macro BS; checking whether the MS is able to access the macro BS, when determining not to hand over to the small cell; handing over to the small cell, when not being able to access the macro BS; and transmitting small cell penetration information to the macro BS, when being able to access the macro BS.
