    Abstract: A gateway device (3, 4) and a configuration client (2) for supporting selective forwarding of messages published to a group address or a virtual address in a network (16, 17) of communicatively coupled communication devices (15), such as a Bluetooth Mesh system (1). The configuration client (2) maintains a mapping between unicast addresses of communication devices (15) and group and virtual addresses in the network (16, 17). At receipt of a message comprising a group or virtual address, the gateway device (3, 4) retrieves, from the configuration client (2), the unicast addresses of those communication devices (15) collectively identified by the group or virtual address in the received message. If the retrieved unicast addresses are all serviced by the gateway device (3, 4), the message is transmitted by the gateway device (3, 4) on all interfaces corresponding to the communication devices (15) addressed by the retrieved unicast addresses.

    Abstract: A method of establishing connection between a first node in a wireless network and a second node in said wireless network, wherein each of said first and second nodes comprise a primary radio receiver and a wake up receiver, each of said nodes comprising a Radio Frequency, RF, switch, arranged to connect one of said primary or secondary radios to a radio antenna, said method comprising the steps of transmitting, by said first node, to a wake-up receiver of a second radio node, a wake- up signal that indicates a frequency channel on which the second radio node is to transmit a response, receiving, by said first node, in response to transmitting said wake-up signal, response from said second radio node on the frequency channel indicated, and establishing, by said first node, a connection between said first and second nodes in order to transfer data between said first and second nodes. The present disclosure also relates to corresponding mesh nodes and a computer program product.

    Abstract: In a mobile communications system that provides packet data services, a packet data connection is established between a mobile station and a radio access network. The state of the connection specifies one of plural different types of radio channels bearing the connection over the radio interface. The connection state preferably also may specify other parameters including for example, one of plural different mobility management schemes tailored to the selected channel type or channel bit rate(s). The connection is dynamically adapted to an optimal state based on one or more conditions relating to the connection. For example, one or more traffic parameters are determined for the connection and used to predict a future value of that parameter. Based on the predicted parameter value or values, an optimal connection state is determined and implemented. If the traffic parameter value changes later in the connection, another connection state may be dynamically selected that is better suited in accordance with the newly predicted parameter.

    Abstract: Delays on a common radio communications channel employed by plural mobile stations to communicate with a base station located in a corresponding geographical cell area are minimized by adapting transmission power based on traffic conditions. For lower traffic loads, a higher transmission power is permitted. For higher traffic loads, a lower power level is set. A transmit power level is determined using a desired signal ratio, such as a target CIR, a transmission path loss over the radio communications channel, and an interference value. One or more adaptive power parameters are also employed in that determination to adapt the open loop power control based on one or more current communications conditions and/or characteristics of the mobile station. For example, an adaptive power parameter may be a function of a current interference in a base station cell either alone or in combination with a current interference in one or more neighboring cells. The adaptive power parameter may also account for a type of data packet connection to be employed between the mobile station and the base station after random access, a mobile station's subscription, a current temperature of the mobile station, a current base station used by the mobile station, a current estimated path loss between the mobile station and base station, and/or other factors.

    Abstract: In a cellular telecommunications system or network, tags are associated with one or more system control parameters. For example, a given tag value may be indicative of particular values for one or more system information parameters. In each cell, a base station (BS) transmits or broadcasts currently valid tag values. System information blocks including the system information parameters themselves (which correspond to particular tag(s)) are also broadcast by base stations. A mobile station receiving a valid tag value from a base station determines whether or not it has to read system information block(s) corresponding to that tag value depending upon whether the base station has already stored or cached such block(s) corresponding to the tag value. As will be appreciated by those skilled in the art, different embodiments of the instant invention may result in the mobile station not having to re-read identical system information each time it changes cells, or while moving in the same cell. This may conserve radio resources and reduce battery consumption, thereby improving standby time of the mobile station.
