Managing a plurality of non-coordinated radio access networks (RANs) connected to the core network is provided by acquiring information indicating that a wireless communication device is connected to a base station in a first of the plurality of RANs, and information indicating a location of the wireless communication device, acquiring information identifying at least a second of the plurality of RANs to which the wireless communication device may connect based on the location of the wireless communication device, and information indicating available frequencies in the second RAN via which frequencies the wireless communication device is allowed to access a network being accessible by the mobility management node, said network being operated by an operator different from those operating the first and second RANs, and delivering the information identifying the second RAN and the information indicating available frequencies in the second RAN to the wireless communication device.

Managing non-coordinated radio access networks

Methods, nodes and computer program products control radio channel deployment when using un-licensed carriers in a wireless communication network and control mobility and/or load balancing target selection when using un-licensed carriers. When performed in an access node, unlicensed carrier intrinsic cell channel load is determined in a cell served by the access node based on one or more predetermined channel load indicators and neighbor cell channel load information is obtained, from one or more neighboring access nodes. The neighbor cell channel load information includes unlicensed carrier channel load in respective cells based on the one or more predetermined channel load indicators. At least one channel deployment operation is initiated based on an outcome of one or more comparative operations including the determined unlicensed carrier intrinsic cell channel load and/or the obtained neighbor cell channel load information.

Mobility and load balancing target selection for unlicensed carriers

The invention relates to methods and devices for managing a plurality of non-coordinated radio access networks. In an aspect, a method of a mobility management node is provided for managing a plurality of non-coordinated radio access networks (RANs) in a wireless communication network. The method comprises receiving, from a base station of a first of the plurality of RANs, information indicating frequencies available in the first RAN for accessing a network served by the mobility management node, acquiring information identifying a base station of a second of the plurality of RANs, said network being operated by an operator different from those operating the first and second RANs; and transmitting, to the base station of the second RAN, the information indicating the frequencies available in the first RAN for accessing said network.

Example embodiments presented herein are directed towards a wireless device and core network node, as well as corresponding methods therein, for managing a data flow between a network access type 1 and a network access type 2. According to some examples, access type 1 may be a 3GPP access and access type 2 may be a non-3GPP access. The wireless device is connectable to both the networks of access types 1 and 2.

Node and method for managing a data flow between networks of different access types

The present disclosure relates to a method, performed in a network node of a first network, for designating one or more cells of a second network as neighbouring cells to the first network. The method comprises selecting a set of carriers employed in the second network and transmitting information for the selected set of carriers to a wireless device served by the first network. Measurement reports are received for respective carriers from the wireless device. The network node determines neighbour cell relations between the first network and one or more cells of the second network based on the received measurement reports.

Inter network cell relationship mapping

The invention relates to methods and devices for facilitating selection of network access for one or more wireless communication devices. A network connectivity selection node () establishes (S) a connection with at least one reporting wireless communication device (), receives (S) information regarding topology of networks via which one or more modems (-) with which said at least one reporting wireless communication device is equipped is capable of performing access, as well as a current location of the at least one reporting wireless communication device, and stores (S) the received network topology information and said location. Said node further establishes (S) a connection with the one or more wireless communication devices for which selection of network is to be facilitated, determines (S), from the network topology information, a recommendation on which network access the one or more wireless communication devices for which selection of network is to be facilitated should perform at said location, and transmits (S), the recommendation to the one or more wireless communication devices for which selection of network is to be facilitated.
