Abstract:
The present disclosure relates to a method performed in a radio communications network which is configured to enable multipath communication. The method comprises providing an explicit indication (36) that a path within a multipath connection is a backup path prior to establishment on or handover to a radio link of the backup path, transmission (37) of the explicit indication to the base station, where it is interpreted (38). This allows an early indication that the path is a backup path and allows the base station to handle and prioritise use of radio network resources (39) and/or connection characteristics for the radio link (40). The explicit indication may be in the radio level signalling or in handover signalling.
Abstract:
It is provided a method, comprising configuring a first internet protocol address and a second internet protocol address different from the first internet protocol address for a connection between an apparatus performing the method and a packet data network; assigning the first internet protocol address to a first data path for the connection and to assign the second internet protocol address to a second data path for the connection, 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.
Abstract:
Methods, systems, and apparatuses are provided for managing communication of data to/from a device. For example, multiple client applications running on the device can communicate to a second device through a same primary socket connection. A mux module can receive data from two different client applications over respective client connections. The received data can include header information identifying the second device as the destination. When the first data from a first client application is received at the mux module, the primary socket connection can be created; and when the second data from a second client application is received, the existing primary socket connection can be identified and re-used. The primary socket connection can be managed by a controller of the mux module.
Abstract:
Systems and methods for dynamic transport protocol layer management for avionics system are provided. In one embodiment, a method for providing dynamic transport protocol layer management for avionics applications comprises: selecting an air-ground communication IP datalink based at least in part on criteria defined by one or more profile and policy definitions; selecting a transport layer protocol based on the air-ground communication IP datalink selected and further based on criteria defined by the one or more profile and policy definitions; and instantiating a port entity to transport air-ground communications between a first on-board application and the air-ground communication IP datalinkthrough a Socket API, based on the selected transport layer protocol.
Abstract:
Techniques of Transmission Control Protocol (TCP) packet transmission for wireless communication are provided for a user equipment (UE). The UE receives a plurality of TCP packets on a downlink channel from a network. In response, the UE generates a plurality of TCP Acknowledgment (ACK) packets corresponding to the plurality of received TCP packets. The plurality of TCP ACK packets is prioritized based on certain criteria. A TCK ACK packet with a highest priority among the plurality of TCP ACK packets is selected. The selected highest priority TCP ACK packet is then sent to the network on an uplink channel.
Abstract:
The present disclosure provides methods for establishing secure communication with a device, and also provides corresponding devices, network application functions, NAFs, bootstrapping servers and systems. In one example, there is provided a method for enabling secure communication between a server and a client associated with a machine- to-machine, M2M, device, the method comprising the steps of bootstrapping, using Generic Bootstrapping Architecture, GBA, a shared secret based on a security association between a network and a card associated with the M2M device and securing the communication between the client and the server using the shared secret within at least the Datagram Transport Layer Security, DTLS, protocol.
Abstract:
In embodiments, apparatuses, methods, and storage media may be described for monitoring channel quality of a radio link between a secondary evolved NodeB (SeNB) and a user equipment (UE) in a wireless communication network configured for dual connectivity. In embodiments, the UE may generate one or more indications of a channel quality of the SeNB-UE radio link and forward the indication to the SeNB. Based on the indication, the UE may receive a radio resource control (RRC) message from a master eNB (MeNB) related to the SeNB-UE radio link. Other embodiments may be claimed.
