Abstract: A method performed by a radio node for handling a radio fingerprint during network degradation in a wireless communications network is provided. The radio node obtains an indication about a network degradation at location X in the wireless communications network. The radio node decides whether one or more radio fingerprints of respective one or more User Equipments, UEs, are suffering from the network degradation at location X. When one or more radio fingerprints of respective one or more UEs are suffering from the network degradation at location X, the radio node provides to the one or more UEs an indication that the location X is suffering from the network degradation. The indication enables the one or more UEs to handle their respective radio fingerprints during the network degradation at location X.

Abstract: A method performed by abase station for handling network degradation in a wireless communications network is provided. The base station receives (201, IS1) from a first UE experiencing a network degradation, a determined type of the network degradation together with an estimated first Timing Advance, TA1, value. Based on the received TA1 value, the base station calculates (202, 1) a location, location X, associated with the network degradation. When a first location, location L1, of a second UE is at a distance from the location X that is below a second threshold, the base station decides (204, 2) a first decision to perform an action to restrain degrading influence from the location X. The first decision is based on the determined type of the network degradation. The base station sends (205, 2) to the second UE, the first decision to perform an action to restrain degrading influence from the location X.

Abstract: Triggering a temporary roaming after an occurrence of an event. In one aspect there is a method for triggering a temporary roaming, which the method includes a first node obtaining information indicating an occurrence of an event. The method further includes after obtaining the information, the first node (i) initiating a broadcast of a warning message providing a notification of the occurrence of the event and (ii) sending toward a second node belonging to a second PLMN a roaming activation request for requesting an activation of a roaming service. The method further includes after sending the roaming activation request, the first node receiving an acknowledgement message authorizing the roaming service and as a result of receiving the acknowledgement message authenticating the roaming service, the first node initiating a broadcast of an alarm message.

Abstract: An entity in a wireless network 100 retains contexts for each wireless terminal 140 served by a serving cell in a serving Radio Node (RN) 110 after that serving cell experiences an outage. The contexts may be retained by the serving RN 110 of the serving cell and/or by the wireless terminal served by the serving cell. The retained contexts are then provided to neighbor RNs 120 to facilitate connection reestablishment for the wireless terminals 140 previously served by the serving cell now experiencing an outage with a neighbor cell, e.g., another cell in the serving RN 110 or a neighbor cell in a neighbor RN 120.

Abstract: There are provided mechanisms for reporting network performance degradation in a communications system. A method is performed by a wireless device. The method includes selecting a first configuration for reporting the network performance degradation when current speed of travel is above a speed threshold, and else selecting a second configuration.

A new reporting of the network performance degradation for one and the same location is only allowed upon expiration of the network-specific timer. The method includes reporting, to a network node in the communications system, network performance degradation as currently experienced by the wireless device using the selected configuration.
