摘要: A transmission method of a femtocell includes the following steps. The femtocell receives and temporarily stores multiple real-time transport protocol (RTP) packets from a UE in a buffer. When the RTP packets are temporarily stored for a time period, the femtocell samples the buffer at a sampling rate to generate multiple CS data packets. The CS data packets include a current CS data packet. When there exists no previous CS data packet received from the UE, the femtocell calculates a timestamp of the current CS data packet according to a current timestamp. When there exists the previous CS data packet, the femtocell calculates the timestamp of the current CS data packet according to the timestamp and a connection frame number (CFN) of the previous CS data packet and a CFN of the current CS data packet.

摘要: After receiving a packet data protocol (PDP) activation request signaling from a user equipment (UE), a base station checks whether to activate a local Internet protocol access (LIPA) function for the UE. If yes, the base station informs a core network (CN) for authentication and signaling control. If the user plane data from the UE is allowed to be transmitted via the LIPA, the base station assigns a private IP address to the UE; and the UE access internet via the base station. The base station determines whether user plane data from the UE passes through the CN; and the CN measures Internet service time provided to the UE. If all user plane data transmitted from the UE are allowed to be transmitted via the LIPA, the base station periodically transmits a data packet to the CN to maintain signaling link.

摘要: 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.
