Abstract: Handling a plurality of Presence Reporting Areas, PRAs, may currently present inconsistencies between the PRAs active in a policy controller and those PRAs active in a network node handling UE mobility, e.g. MME/SGSN. To overcome these and other drawbacks, there are provided enhanced policy controller, network node and method of handling a plurality of PRAs. This method comprises selecting, at the policy controller, a plurality of applicable PRAs; transmitting from the policy controller, and receiving at the network node, the plurality of applicable PRAs; selecting, at the network node from the plurality of applicable PRAs, a number of PRAs to be active at the network node; and transmitting from the network node, and receiving at the policy controller, at least one of: an indication on whether a UE is inside or outside a PRA, and an indication on whether a PRA is or is not accepted to be active by the network node.

Abstract: Embodiments herein relate to systems and methods for providing monitoring services comprising receiving, at an aggregator proxy function, APF in a first Public Land Mobile Network, PLMN, a first event report transmitted by a monitoring function in the first PLMN. The first event report comprising first event information related to a monitoring event, and a request identifier. Further, receiving, at the APF, a second event report transmitted by a monitoring function in the first PLMN. The second event report comprising second event information related to the monitoring event, and said request identifier. After receiving the first and second event reports, the APF transmitting an aggregate event report to a report receiving function not in the first PLMN.

Abstract: The embodiments herein relate to a method in a RAN node for determining which operator that should serve a device when it has been handed over from a source network to a target shared network. When the device has been handed over to the target shared network, the RAN node transmits, to a non-registered CN node in a non-registered domain, a request for an identity of the device. The RAN node transmits a request, to CN nodes in a registered domain, for a serving operator which has registered the device. The RAN node receives information indicating the serving operator. The RAN node determines that the same serving operator which served the identified device in the registered domain should also serve the device in the non-registered domain.
