It is provided a method, comprising monitoring if a second data path is established for a flow, wherein a first internet protocol address is configured for the flow via a first data path between an apparatus performing the method and a packet data network; assigning, if the second data path is established, a second internet protocol address different from the first internet protocol address for the flow via the second data path, wherein at least a part of the first data path belongs to a radio access technology; at least a part of the second data path belongs to the radio access technology; and the part of the first data path is different from the part of the second data path.

The present disclosure provides a wireless screen mirroring method based on IP network connection. The method applied to a screen projection receiving and sending device includes: broadcasting a Wi-Fi beacon based on the Wi-Fi direct connection protocol, detecting the Wi-Fi beacon from the receiving device, sending a Wi-Fi detection request to the receiving device, receiving and responding to the detection request, sending a connection information for establishing a handshake used to establish an RTSP connection and complete the Miracast handshake protocol to the sending device, the sending device gets connection information, according to the connection information for establishing a handshake, analyzing the information and sending alarm information used to indicate that the receiving device has completed the connection. The present disclosure combines the advantages of network connection, wired network and Miracast standard to realize a more stable screen projection method based on wired network or wireless network.

A method, system, or computer program product to enhance the performance of multi-hop cellular networks or other wireless networks is provided. A wireless device (e.g., cellular telephone) is able to communicate with a base-station in a cell of the cellular network over a non-cellular interface via another wireless device in the cell through the use of multi-hopping. By enabling wireless devices to communicate with a base station in such a manner, the effective coverage area of the cellular network is expanded and the effective capacity of the cellular network is improved. Distributed routing, device management, adaptive scheduling, and distributed algorithms can be used to enhance the overall performance of multi-hop cellular networks.

There is a provided herein a proxy at a border between two transport domains, the proxy arranged to deliver packets to a communications device in a first transport domain; the packets received from a server in a second transport domain. The proxy is arranged to: receive a packet from the server, the packet directed to the communications device; and forward the packet to the communications device and reply to the server with a traffic handling offer message, the traffic handling offer message including a plurality of traffic handling options. The proxy is further arranged to receive a selection of a traffic handling option from the server; and apply the selected traffic handling option to packets sent from the server to the communications device via the proxy.

Aspects of the disclosure provide a method for reordering. The method includes receiving, by a terminal device, a stream of data units from a wireless network. The data units have respective sequence numbers. Further, the method includes reordering at a protocol layer in a protocol stack, the data units for a next process according to the sequence numbers, determining a dependency relationship of a data unit to one or more missing data units that have sequence numbers prior to the data unit, and advancing, out of order of the sequence numbers, the data unit to the next process when the data unit is independent of the one or more missing data units.

Registration rejections are reported to a universal integrated circuit card (UICC). Remote access can be provide to registration rejection data stored in the UICC, the registration rejection data can be transmitted to a service provider, one or more UICC applications can be executed based on the registration rejection data, and/or the registration rejection data can be logged or tracked. In addition, action taken by the UICC can be automated based on the registration rejection using artificial intelligence.

A data migration method is disclosed. The method includes: performing, by a source base station, a TCP proxy for user equipment; learning, by the source base station, that the user equipment is to be handed over to a target base station; sending, by the source base station to the target base station, context information including a sequence number of a data packet, and the sequence number of the data packet is a largest sequence number of data packets that have been acknowledged by the user equipment or a smallest sequence number of data packets that have not been acknowledged by the user equipment; and migrating, by the source base station by using the SCTP, the data packets that have not been acknowledged by the user equipment to the target base station.
