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： A gateway device and a configuration client for supporting selective forwarding of messages published to a group address or a virtual address in a wireless mesh network of communicatively coupled communication devices, such as a Bluetooth Mesh system. The configuration client maintains a mapping between unicast addresses of communication devices and group and virtual addresses in the network. The gateway device receives, from the configuration client, unicast addresses of those communication devices collectively identified by the group or virtual address in a received message. When the retrieved unicast addresses are all serviced by the gateway device, the message is transmitted by the gateway device on all interfaces corresponding to the communication devices addressed by the retrieved unicast addresses. When the retrieved unicast addresses are not all serviced by the gateway device, the message is transmitted by the gateway device on all except one of the interfaces.

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 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： 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.
Corresponding apparatuses, wireless communication device, nodes and computer program product and related methods are also disclosed.
