  • Publication number: 20170272948
    Abstract: The invention relates to a method and devices for mutual communication between devices, and to computer programs enabling such communication. According to the invention, in a first device is controlled a transmitter module operable in a local radio communications network to transmit a sequence of radio signal pulses representing a predetermined code. In at least one second device a receiver module is scanning said local radio communications network to detect said predetermined code. A contact network of the user of said at least second device is accessed, and the predetermined code is checked in the second device against the user's contact network for a match stored in the network profiles for the contacts. Then a validation key is fetched, that relates to a matching contact found in said contact network, and a connection establishment request containing the validation key is sent over said local radio communications network from the second device to the first device.

  • Publication number: 20160119862
    Abstract: A method, apparatus and computer program product are provided to facilitate interworking a plurality of cellular radio access networks and wireless local area networks (WLANs). In the context of a method, a set of information is maintained for a plurality of different cellular radio access networks that defines a relative priority of selection among the cellular radio access networks. The method also includes maintaining wireless access selection information defining a relative priority of selection among one or more WLANs relative to the cellular radio access networks. The method also permits the relative priority of the WLANs to be modified without modification of the set of information. For example, the relative priority the WLANs may be modified in a manner specific to the user equipment or specific to a cell. The method may also include causing notification to be provided to user equipment of the set of information and the wireless access selection information.

  • Patent number: 9137832
    Abstract: A provided apparatus is caused to direct establishment of a connection of the apparatus with a core network via a wide area radio access network (RAN), where the core network is coupled to an external network. The apparatus is also caused to select or receive selection of a local area network that is coupled to the same or different external network via one or more local gateways (L-GWs). The apparatus is caused to request selection of a L-GW of the one or more L-GWs from the core network via the wide area RAN, and in response, receive an identity of a selected L-GW. Further, the apparatus is caused to direct contact with the selected L-GW based on the identity, and establishment of a connection of the apparatus with the selected L-GW. The apparatus may thereby be connected to the external network via the local area network and selected L-GW.

  • Patent number: 7944943
    Abstract: A channel inverse multiplexer/multiplexer (IMUX/MUX) (14a) of a MAC sublayer (14) of a UTRAN RNC (11) for providing to a UE (18) traffic (communication signals including in general both control and user data) at a higher rate than the UE can accept over a single channel. The channel IMUX/MUX performs inverse multiplexing of traffic for downlink, and multiplexing of traffic on uplink, and does so in a way that is transparent to all other layers/entities of the UTRAN (11 17) and to the UE (18).

  • Patent number: 7869414
    Abstract: The area of the invention belongs to the transport technologies in UTRAN. This invention concerns a method for multiplexing a data stream onto a transport bearer between an originating network node and a receiving network node in a telecommunications network. This is done in order to ensure the effective usage of transport resources over the two interfaces, i.e. Iub/Iur. To accomplish this the RNC and/or Node B/RNC should check if the there already exists a transport bearer, which can be utilized for HS-DSCH transport over Iub/Iur interface. Because of this a transport bearer identification code or transport bearer id is needed to identify this bearer between RNC and Node B/RNC.
