Communication apparatus and method
First Claim
1. A communication apparatus comprising:
- at least one antenna;
a storage unit configured to store information, the storage unit being an NAND type flash memory;
a state detecting unit configured to detect, at least one time during an operation of the communication apparatus, whether the storage unit is in a busy state in which no data writing is allowed, or in a ready state in which data writing is allowed;
a communication unit configured to perform communication with a destination communication apparatus; and
a communication control unit configured to control the communication unit to inform the destination communication apparatus that a data receiving operation is stopped for a first time period, if the state detection unit detects that the storage unit has entered the busy state,wherein the state detection unit detects that the storage unit has entered the busy state if no write completion response is issued even after a second time period.

Abstract
According to one embodiment, a communication apparatus includes a storage unit, a state detecting unit, a communication unit, and a communication control unit. The storage unit configured to store information. The state detecting unit configured to detect, at least one time during an operation of the communication apparatus, whether the storage unit is in a busy state in which no data writing is allowed, or in a ready state in which data writing is allowed. The communication unit configured to perform communication with a destination communication apparatus. The communication control unit configured to control the communication unit to inform the destination communication apparatus that a data receiving operation is stopped for a first time period, if the state detection unit detects that the storage unit has entered the busy state.

11. A communication method comprising:
-
detecting, at least one time during communication, whether a storage unit for storing information is in a busy state in which no data writing is allowed, or in a ready state in which data writing is allowed; performing communication with a destination communication apparatus via at least one antenna; and controlling communication to inform the destination communication apparatus that a data receiving operation is stopped for a first time period, when it is detected that the storage unit has entered the busy state.
