Abstract: In a method for accessing a legacy wireless network, a radio access network (RAN) node in the legacy wireless network receives an access message sent by a User Equipment (UE) attempting to access the legacy wireless network. The access message includes mobility management entity (MME) information identifying an MME accessed by the UE in an evolved network. The MME information is added by the UE from a temporary identity (ID) allocated by the MME to a first P-Temporary Mobile Station Identity (P-TMSI) in the access message. The RAN node selects a corresponding Serving GPRS Support Node (SGSN) in the legacy wireless network for the UE according to the first P-TMSI in the access message.

Abstract: The present invention discloses a method. In a process of splitting and sending a data packet, after dividing a data packet to be sent to a destination node into multiple sub data packets, a front end node performs inter-packet combination encoding on the sub data packets in a combination encoding mode, and sends obtained encoded sub data packet groups to the destination node. Even if a channel state of a transmission path suddenly deteriorates, because the destination node does not need to wait to receive all encoded sub data packet groups provided that an original data packet can be parsed out by combining content in a received encoded sub data packet group and a corresponding decoding mode, a process in which the destination node receives the data packet is less affected by a sudden network case, and transmission efficiency is not significantly affected.
