Abstract
A receiving unit wirelessly receives a packet communication signal. When receiving a packet included in the packet communication signal is failed, a requesting unit issues a retransmission request for retransmitting the packet. A storing unit stores therein packets included in packet communication signals received before and after issuing the retransmission request. A setting unit sets an order of transferring the packets stored in the storing unit to a control unit in an order of receiving the packets without a fail. A transferring unit transfers the packets stored in the storing unit to the control unit in the order set by the setting unit.
Claims8
An information processing apparatus comprising:
- a receiving unit that wirelessly receives a packet communication signal including a plurality of packets in units of communication;
- a requesting unit that, when the receiving unit fails to receive a packet included in the packet communication signal, issues a first retransmission request for retransmitting the packet;
- a storing unit that stores therein packets included in a first packet communication signal received before the first retransmission request is issued and packets included in a second packet communication signal received after the first retransmission request is issued including a retransmitted packet;
- a setting unit that sets a first order of transferring the packets stored in the storing unit to a control unit in an order of receiving the packets when the receiving unit receives the packets without a fail;
- and
- a transferring unit that transfers the packets stored in the storing unit to the control unit in the first order, wherein
- when the receiving unit fails to receive the retransmitted packet, the setting unit further sets a second order of transferring a dummy packet as a replacement of the retransmitted packet in an order of receiving packets having same content as that of the transmitted packet without a fail, and
- the transferring unit transfers the dummy packet to the control unit in the second order.
An information processing method comprising:
- receiving wirelessly a packet communication signal including a plurality of packets in units of communication;
- issuing, when a reception of a packet included in the packet communication signal is failed, a first retransmission request for retransmitting the packet;
- storing packets included in a first packet communication signal received before the first retransmission request is issued and packets included in a second packet communication signal received after the first retransmission request is issued including a retransmitted packet in a storing unit;
- setting a first order of transferring the packets stored in the storing unit to a control unit in an order of receiving the packets when the packets are received without a fail;
- and
- transferring the packets stored in the storing unit to the control unit in the first order, wherein
- when the reception of the retransmitted packet is failed, the setting includes setting a second order of transferring a dummy packet as a replacement of the transmitted packet in an order of receiving packets having same content as that of the retransmitted packet without a fail, and
- the transferring includes transferring the dummy packet to the control unit in the second order.
A computer program product comprising a non-transitory computer-usable medium having computer-readable program codes embodied in the medium that when executed cause a computer to execute:
- receiving wirelessly a packet communication signal including a plurality of packets in units of communication;
- issuing, when a reception of a packet included in the packet communication signal is failed, a first retransmission request for retransmitting the packet;
- storing packets included in a first packet communication signal received before the first retransmission request is issued and packets included in a second packet communication signal received after the first retransmission request is issued including a retransmitted packet in a storing unit;
- setting a first order of transferring the packets stored in the storing unit to a control unit in an order of receiving the packets when the packets are received without a fail;
- and
- transferring the packets stored in the storing unit to the control unit in the first order, wherein
- when the reception of the retransmitted packet is failed, the setting includes setting a second order of transferring a dummy packet as a replacement of the transmitted packet in an order of receiving packets having same content as that of the retransmitted packet without a fail, and
- the transferring includes transferring the dummy packet to the control unit in the second order.
