There is provided a solution for detecting a condition of at least one cell. The solution includes determining, for each predetermined channel, the number of failed attempts in establishing a connection to a cell, and communicating the information to the next connected cell. The cell may then apply the information in determining whether a cell is degraded or not.

Cell degradation detection

In one exemplary aspect of this invention a method includes receiving at a user equipment from a wide area network access node information identifying at least one predetermined radio frequency carrier; initiating, in response to a presence of an interferer on a radio frequency carrier that is being used for a current connection between the user equipment and the network access node, a connection re-establishment procedure, where the interferer has the potential to cause a radio link failure of the current connection on the radio frequency carrier; and transmitting a connection re-establishment request to the network access node on the predetermined radio frequency carrier. The interferer can be a closed subscriber group network access node that the user equipment is not authorized to gain access to.
