Embodiment Construction

[0036] For the sake of clarity, the drawings are schematic and simplified, and they only show details that are necessary for the understanding of the embodiments presented herein, while other details have been omitted. Throughout, the same reference numerals are used for the same or corresponding parts or processes.

[0037] As part of the development of the embodiments described herein, the so-called ambiguity problem briefly described in the background section above will be discussed further below.

[0038] Consistent Mobility Robust Optimization One of the goals of MRO is to make information about RLF reports available in the fault-originating network nodes, assuming that these network nodes are responsible for performing appropriate adjustments or corrections, such as for example adjusting the lag ( hysteresis) to avoid switching too late, those network nodes. These adjustments or corrections may be applied to the pair of cells associated with the network node in which th...

Abstract

A method performed by a network node (111, 112), namely eNB, for handling communications in a radio communications network (100) is provided. The network node (111, 112) is configured to be in the radio communications network (100). The network node (111, 112) receives a report of a radio link failure (RLF) report of user equipment (UE), which RLF report comprises an identity of a re-establishment cell, configures an RLF indication comprising the received RLF report to further comprise a first indication of the cell identity of the current cell the UE is connected and / or a second indication of a result of a comparison between the cell identity of the cell the UE was connected to upon sending the RLF report and the identity of the re-establishment cell, and sends the RLF indication to another network node (110), namely eNB.

Description

technical field [0001] Embodiments herein relate to handling communications in a radio communications network. In particular, embodiments herein relate to a network node and methods therein for handling communications in a radio communications network. Background technique [0002] In a typical radio communication network, wireless terminals, also called mobile stations and / or user equipment UE, communicate with one or more core networks via a radio access network RAN. A radio access network covers a geographical area divided into cell areas, each served by a base station such as a radio base station RBS, which in some networks may also be called eg "NodeB" or "eNodeB". A cell is a geographical area where radio coverage is provided by a radio base station at a base station site, or by an antenna site if the antenna and radio base station are not co-located. Each cell is identified by an identity within the local radio area, which is broadcast in the cell. Another identity...
