Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.

A system includes a self-backhauled eNodeB which communicates via a radio interface with an anchor eNodeB, where the self-backhauled eNodeB is made reachable in an operator's network via a serving gateway and where the serving gateway of the self-backhauled eNodeB owns an IP address associated with the self-backhauled eNodeB. The system receives a packet destined for the self-backhauled eNodeB and classifies the packet to a bearer associated with a self-backhauled link to the self-backhauled eNodeB.

This invention extends routing mechanisms that use link metrics for route selection so that: A link metric cross correlation vector is determined for all links, where each element in the vector corresponds to some other link, and reflects the change in the link metric value if a data flow would already use this other link. The invention further describes a specific embodiment where all cross-correlating links are adjacent to each other, i.e., they terminate or originate in a common node. A mechanism is described to create an extended routing graph. This extended graph permits the use of standard polynomial time algorithms that simultaneously construct the optimal route and find the optimal route metric (such as shortest-path algorithms) also for the adjacent link cross-correlating case.

Method and arrangement for route cost determination and selection with link cost interaction

The invention is directed towards determining an access node () for a terminal () in a network () having one or more access nodes capable of providing access to the terminal based on one or more access technologies. Access node is selected through determining whether at least one network parameter provided by a network node () is required as input for the access node selection for the terminal. If it is determined that the at least one network parameter is required as input, the network parameter is obtained and an access node possibly together with access type for the terminal is selected at least based on said network parameter.

Access node selection in a network

A method in a first user equipment (UE) connectable to a second user equipment (UE) via a communication network or via a direct radio communication link, of using a direct radio communication link for communication between the UEs is initiated when one of the UEs receives probe signaling information comprising a first probe token via the communication network. The UEs exchange probe signaling messages including a second and/or the first probe token at least partly according to the probe signaling information, such that one of the UEs can compare the probe tokens, generate a probing report and provide the probing report to the communication network, or to the opposite UE for evaluation in case of a successful comparison and such that a direct radio communication link can be used for communication with UEin response to receiving instructions to use the second direct radio communication link from the entity by which the probing report was evaluated.

Methods and arrangements for direct mode communication

A communication system is provided which is arranged for accessing a network by a group of first access paths and a group of second access paths. The first and second access paths have a different access technology. An access path monitor is provided for obtaining status information related to the access paths in accordance with the monitoring procedure. An access controller is provided for selecting an access path for a communication session in accordance with a selection procedure and in dependence on the status information. A modifier is provided for modifying one or both of the monitoring procedure and the selection procedure in accordance with a modification procedure and in dependence on decision information.

A method implemented in an anchor base station configured performing a proxy operation at an anchor base station in which the anchor base station acts as a proxy between a second S-GW or an MME node and a self-backhauled base station. The method includes receiving a data packet destined for the user equipment and mapping the received data packet from an incoming General Packet Radio Service (GPRS) Tunneling Protocol (GTP) tunnel to an outgoing GTP tunnel. The method also includes receiving a control message and modifying elements of the control message while copying other elements in the control message and forwarding the control message between the self-backhauled base station and the second S-GW or MME node.

A method of access management in a communication system comprising a terminal, a first access point, a second access point and a network is described. The first access point offers a first access connection to the terminal and the second access point offers a second access connection to the terminal. A first network connection is provided between the network and the first access point and a second network connection is provided between the network and the second access point. Access connection information associated with at least one of the first and second access connections is monitored, and network connection information associated with at least one of the first and second network connections is monitored. An access connection selection decision is based on the monitored access connection information and the monitored network connection information.

The technology downloads and upgrades terminal software of a communications device over-the-air in a efficient and fail-safe manner. The communication device is provided with radio software from a server via a wireless network including a number of access networks. A download is initiated of radio software designed for a first of two different radio access technologies of the communication device. One of the two radio access technologies of the communication device is selected for downloading the software. The radio software is downloaded via the selected available radio access technology. The radio software designed for the first radio access technology is stored in memory.

A method and arrangement for making a handover decision in a multi-access communication network is disclosed. A first set of criteria is determined for when a handover between at least two access paths should be performed and a report is sent when at least one criterion of a first set of criteria is fulfilled. A second set of criteria is determined for when a handover between said at least two access paths should be performed and a report is sent when at least one criterion of said second set of criteria is fulfilled. One or more data sessions of at least one user terminal network are determined to be handed over based on the sent reports and a core network anchor and a terminal anchor are directed to execute a handover by re-routing said determined data sessions from one access path to an alternative access path.

Packets may be routed in a heterogeneous communications network as follows: for a set of packets comprising at least one packet to be transmitted from a sending node, said sending node being able to handle communication according to at least two access technologies,&#x2014;selecting in a selection unit in the sending node an access technology for use when transmitting the set of packets,&#x2014;selecting a receiving node in the network to which to transmit the set of packets among nodes in the network that are able to handle said selected access technology&#x2014;transmitting the set of packets to the selected receiving node using the selected access technology. Alternatively, a set of packets may be transmitted to one or more nodes using at least two different access technologies. Depending on the transmission quality, one node may be selected to forward the set of packets.

A mobile ambient network (MAN) negotiatoris provided for negotiating with ambient access networks (AANs)on behalf of a MANto select a particular AAN to handle a wireless communication session for the MAN. The MAN is, e.g., either a user terminal (UT) or a private area network (PAN). The negotiations performed by the MAN negotiator on behalf of the MAN include establishing a secure, trusted relationship between the MAN and the AAN, as well as negotiating costs, billing arrangements and the like. The MAN negotiator communicates with the MAN via a dedicated wireless communication channel but preferably communicates with the AANs via non-wireless, i.e. fixed, connections.

In a multi-access communication system, a terminal is kept reachable through a first access network, which is most resource efficient one of the available access networks for keeping the terminal reachable. The terminal scans passively for the existence of usable base stations for other access networks of the system and reports data associated with such existences to the first access network. When a request for a call to the terminal is received, a paging is performed in the first access network. The paging message comprises information about preferred access network, based on the reported data of the existence of usable base stations or access points of other access networks. The terminal connects to the preferred access network and performs a call set-up directly in the preferred access network.
