摘要： A method of a transmitter node is disclosed, for conveying a message selected from a collection of messages to a receiver node. The method comprises mapping the message to a current codeword based on a previous codeword and/or based on a counter value, and transmitting the current codeword to convey the message to the receiver node. A method of a receiver node is also disclosed, for detecting a message selected from a collection of messages by a transmitter node. The method comprises mapping a candidate message from the collection of messages to a candidate codeword based on a previous codeword and/or based on a counter value, receiving a current codeword from the transmitter node, and detecting the candidate message when the current codeword coincides with the candidate codeword. A method of a provisioning node is also disclosed, for controlling conveyance of a message selected from a collection of messages from a transmitter node to a receiver node. The method comprises providing, to the transmitter node and to the receiver node, information for mapping a message from the collection of messages to a current codeword based on a previous codeword and/or based on a counter value. Corresponding apparatuses, wireless communication device, nodes and computer program product are also disclosed.

摘要： A master device 103 and a method for transmitting a message towards a destination node. The master and the destination are operating in a network 100. The master has a Slave Neighbour Table (SNT) and a Master Neighbour Table (MNT). When the identity of the destination is comprised in the SNT, the master unicasts the message to the slave having the same identity as the destination, otherwise the master determines if the identity of the destination is in the MNT. If so, the master unicasts the message to the neighbour master having the same identity as the destination or to the neighbour master being the master of the neighbour slave having the same identity as the destination; otherwise the master multicasts the message to all neighbour masters comprised in the MNT. When the identity is neither comprised in the SNT nor in the MNT, the master broadcasts the message.

摘要： The present disclosure relates to methods and arrangements in a private address resolving node of a personal area network deploying Bluetooth low energy, BLE and in particular to methods and arrangements for proactively resolving periodically updated private addresses. When performed in a private address resolving node of a personal area network deploying Bluetooth low energy, BLE, a method comprises resolving a periodically updated private address of a private address generating node connected to the private address resolving node. The private address is used in addressing messages from the private address resolving node to the private address generating nodes. The method comprises receiving (S41), from a private address generating node in the personal area network, an Identity Resolving Key, IRK, the IRK being received over an encrypted link established between the private address resolving node and the private address generating node and receiving (S43), from the private address generating node, private address update information defining when and how to update the private address of the private address generating node. Based on the received IRK and the received private address update information, an updated private address to be used when addressing a next message to the private address generating node is determined (S45).

摘要： 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.

摘要： A radio base station in a mobile communication network sends a handover request message to multiple target base stations to initiate handover of a wireless device. The radio base station maintains one or more handovers counters used for monitoring and evaluating performance. The base station receives one or more handover response messages from respective target base stations. In response to receiving the one or more handover response messages, the base station increments a handover counter associated with the wireless device once regardless of a number of the handover response messages received.

摘要： Systems and methods of using a mesh network to support a legacy protocol in a communication network are provided. In one exemplary embodiment, a method (1100, 1200) may be implemented by a mesh node (603, 703, 900) in a mesh network (602, 702) for emulating (1101) direct wireless communication between a client (601, 701) and a server (607, 707) according to a legacy attribute protocol (ATT) that does not support mesh networking. Further, the step of emulating may include replicating (1201), by each mesh node of the mesh network, a server database of the server to obtain a network proxy database. Further, the step of emulating may include forwarding (1203), by each mesh node, an ATT procedure of the legacy ATT between the client and the server using the network proxy database.
