Terminologies

The following commonly terminologies are used in the embodiments and are elaborated below:

Radio network node: In some embodiments the non-limiting term radio network node is more commonly used and it refers to any type of network node serving UE and/or connected to other network node or network element or any radio node from where a UE may receive a signal. Examples of radio network nodes are Node B, Base Station (BS), Multi-Standard Radio (MSR) radio node such as MSR BS, eNode B, network controller, Radio Network Controller (RNC), base station controller, relay, donor node controlling relay, Base Transceiver Station (BTS), Access Point (AP), transmission points, transmission nodes, Remote Radio Unit (RRU), Remote Radio Head (RRH), nodes in Distributed Antenna System (DAS) etc.

Network node: In some embodiments a more general term “network node” is used and it may correspond to any type of radio network node or any network node, which communicates with at least a radio network node. Examples of network node are any radio network node stated above, core network node, e.g., Mobile Switching Centre (MSC), Mobility Management Entity (MME), etc., Operation and Maintenance (O&M), Operating Support Systems (OSS), Self-Organizing Network (SON), positioning node, e.g., Evolved Serving Mobile Location Center (E-SMLC), Minimization of Drive Test (MDT), etc.
