Abstract: A method, system, apparatus, receiving device, and sending device for data retransmission are provided. The method includes that: the transmitting party numbers the packet, and transmits the numbered packet to the receiving party; when receiving the lost packet information fed back by the receiving party, retransmitting the lost packet via the retransmission channel. Using the present invention, the phenomenon of the lost packet can not be retransmitted during transmitting packet process in the wireless access network is avoided, the transmission mechanism of broadcast/multicast service in the wireless access network is improved, and the reliability of the wireless transmission channel is improved.

Abstract: A method of communication between the terminals is provided, which includes: the access network corresponding to the resource terminal receiving the packet sent by the resource terminal; determining the access network and the core network corresponding to the target terminal of the packet; if the target terminal of the packet together with the resource terminal is under the same core network but corresponding to the different access network, the access network corresponding to the resource terminal sending directly the packet to the access network corresponding to the target terminal; and the access network corresponding to the target terminal sends the packet to the target terminal. A access network and a wireless network are provided, too. In the solution, since the packet between the terminals corresponding to the different access network under the same core network is directly transferred between the access network, without the help of the core network, therefore, the communication between the terminals can reduce the load of the core network.

Abstract: A communication method among network nodes based on WiMAX network frame is disclosed, the said WiMAX network frame comprises connectivity service network CSN and access service network ASN; the private address is taken to perform communication among the network nodes, the said communication method comprises the following steps: distributing private address space for each ASN under same CSN, setting IP packet redirection unit in ASN; the said IP packet redirection unit confirms the located private address space of the destination address of the IP packet, and performs the forwarding process for the IP packet according to the confirmed result. An access service network and WiMAX network frame are also provided in the embodiment of the present invention.
