    Abstract: The present disclosure relates to a method, performed in a single IP-address source node in a wireless communication network, of establishing a multipath TCP, MPTCP, connection for transfer of TCP datain MPTCP subflows to a destination node. The single IP-address source node receives (S31) an MPTCP trigger to activate a multipath TCP connection. One or more source TCP ports are selected(S32), wherein each source TCP port is selected to constitute a starting point of an MPTCP subflow. One or more MPTCP notifications are sent (S33) to the destination node. Each MPTCP notification includes information on a selected source TCP port. The single IP-address source node receives (34) an acknowledgment of each MPTCP notification from the destination node. The present disclosure also relates to corresponding method performed in a destination node and a wireless device configured for establishing an MPTCP connection.

    Abstract: 一种确认报文发送方法及其设备,用以减少空口确认报文的发送,提高空口的资源利用效率。通信设备的RLC协议实体单元接收到所述通信设备的TCP协议实体单元发送的未携带有数据信息的TCP确认报文后,丢弃当前接收到的TCP确认报文,或者根据RLC确认报文的发送情况,确定是否向对端通信设备发送TCP确认报文,并根据确定结果进行相应处理;所述通信设备的RLC协议实体单元接收到对端通信设备发送的RLC确认报文后,若根据当前接收到的RLC确认报文确定需要发送TCP确认报文,则根据当前接收到的RLC确认报文向所述通信设备的TCP协议实体单元发送TCP确认报文。

    Abstract: A communication system is disclosed comprising a gateway, a number of base stations, and a mobile device. The gateway holds information mapping address data for each base station to information identifying a respective cell operated by that base station. A base station obtains information identifying a cell operated by a neighbour base station and provides this information to the gateway. The gateway obtains from the information held address data for the neighbour base station based on the information identifying the cell operated by the neighbour base station. The gateway generates and sends a message including address data to the base station. The base station receives the message and establishes a connection with the neighbour base station using the address data.
