Abstract: There are provided measures for enabling/realizing an inactive communication mode, namely an inactive mode for the operation of terminal equipment and network equipment in a communication system. Such measures exemplarily comprise operation in a connected mode, in which a data plane connection and a control plane connection are established between a terminal equipment and a network equipment, transition from the connected mode to an inactive mode upon data plane inactivity, and operation in the inactive mode, in which the data plane connection is released and the control plane connection is maintained between the terminal equipment and the network equipment.

Abstract: Disclosed is a method comprising transmitting a beam switch request from a first distributed unit to a second distributed unit. The first distributed unit then receives a beam switch acknowledgment from the second distributed unit. The first distributed unit transmits a beam switch notification to a central unit, wherein the first distributed unit and the second distributed unit are at least partly controlled by the central unit. The first distributed unit further transmits a beam switch command to a terminal device.

Abstract: A method may include receiving a request for conditional handover from a source node. The method may also include sending a conditional handover request acknowledgment message in response to the request. The method may further include sending a conditional handover cancellation message to a source node. The conditional cancellation message may include a genuine cancellation or a modification-related cancellation. Further, the method may include receiving a response message from the source node in response to the conditional handover cancellation message. In addition, the method may include deciding to keep or release user equipment context based on the response message.

Abstract: There are provided measures for improvement of coverage hole analysis. Such measures exemplarily include detecting a radio link failure, producing a failure report including information indicative of a radio condition during a time period between said radio link failure and a successful establishment of a radio link, detecting said successful establishment of said radio link, and transmitting, after detection of said successful establishment of said radio link, said failure report.

Abstract: There are provided measures for enabling/realizing more efficient radio link problem handling in a mobile communication system. Such measures exemplarily comprise detecting a radio problem of a radio link carrying a network connection of a communication device, and initiating a recovery procedure for recovering the connection on said radio link and a re-establishment procedure for re-establishing the connection on an alternative radio link, upon detection of the radio link problem, before a radio link failure of said radio link is declared.

Abstract: Radio access network controller-based mobility optimization is disclosed. Mobility reports are received at a radio access network controller from multiple network node devices, each mobility report reporting at least one individual failure event to complement one or more aggregated mobility event counters and/or one or more aggregated performance measurement reports. The mobility reports are related to client devices in one or more service areas. The radio access network controller analyzes the received mobility reports. In response to the analyzing resulting in a perceived need for an update of a cell configuration of a service area of the one or more service areas, the radio access network controller determines updated cell configuration information for the service area. The updated cell configuration information is transmitted from the radio access network controller to-wards at least one network node device in the service area.
