Abstract: Identification of network nodes (110a-c) of a first Radio Access Technology, “RAT”, and of a wireless communication network (100), which network nodes (110a-c) are at least potentially neighboring each other. Multiple information sets associated with multiple communication devices (120a-c), respectively, are obtained (204a-b; 401). Each communication device (120a-c) supports both the first RAT and another, second RAT. Each information set, thus associated with a communication device (120a), identifies a network node (110a) of the first RAT, and one or more network nodes (111a) of the second RAT that have been identified by the communication device (120a) when the communication device (120a) was associated with a communicative connection to said identified network node (110a) of the first RAT. The network nodes (110a-b) of the first RAT that are at least potentially neighboring each other are then identified (205; 402) based on the obtained multiple information sets.

Abstract: Methods, nodes and arrangements for supporting identification of one or more neighboring network nodes comprised in a wireless communication network. A communication device is associated with a communicative connection to a first network node, e.g. a serving base station. The communication device obtains a first identifier identifying the first network node, and transmits the obtained first identifier in an uplink so that the first identifier is receivable by one or more other, second network nodes, e.g. non-serving base stations. Receipt of the first identifier by a second network node enables identification of the first radio network node as neighboring said second radio network node. The second network node obtains, based on the first identifier, an address of the first network node, and/or a second identifier uniquely identifying the first network node, in the wireless communication network.

The first indicator indicates whether a mobile device is allowed to access or is barred from accessing the network. The system information further comprises a second indicator indicating an EACC. The second indicator indicates whether a mobile device is allowed to access or is limited from accessing the network. Limited access may entail blocking a mobile device from initiating communications with the network, blocking the mobile device from receiving network initiated communications, or both.
