Abstract: The disclosure provides a method and a system for transmitting wireless data streams. After a user equipment sends a packet data protocol context activation request signaling to a base station, the base station checks whether the user equipment is allowed to activate a local Internet protocol access (LIPA) function. If the base station decides that the user equipment is allowed to activate the LIPA function, the base station instructs a core network to execute authentication accordingly. The base station disconnects a signaling connection between the base station and the core network. The base station assigns a private IP address to the user equipment, so that the user equipment having the private IP address performs the LIPA function and is directly connected to an external network through the base station without going through the core network, and a data transmission is performed between the base station and the user equipment.

Abstract: The disclosure provides a method and a system for transmitting wireless data stream. After a user equipment (UE) sends a packet data protocol (PDP) context activation request signaling to a base station, the base station checks whether the user equipment is allowed to activate a local Internet protocol access (LIPA) function. If the base station decides that the user equipment is allowed to activate the LIPA function, the base station informs a core network which executes authentication accordingly. The base station disconnects from the core network. The base station assigns a private IP address to the user equipment for implementing the LIPA function, so that the user equipment having the private IP address is directly connected to an external network through the base station without going through the core network.
