    Abstract: An apparatus for use by a communication network control element or function configured to control a communication connection with a communication element or function in a first area and using a specific communication capability, the apparatus being configured to determine that a handover procedure is conducted for the communication element to switch the communication connection from the first area to a second area controlled by a target communication network control element or function to cause sending of a handover related request to the target communication network control element or function for starting a handover procedure, the handover related request including a request for service continuity including an indication that service continuity is required for at least one specific communication session, wherein the request for service continuity indicates that a path switch to the communication network is to be delayed.

    IPC: H04W36/36

    CPC classification number: H04W36/362

    Abstract: The present invention relates to survival time aware mobility and presents handover procedures when considering survival time (ST) requirements. It proposes a mechanism and embodiments to allow a target cell to have the information relating to a joining UE's Survival Time requirements as well as the ST status during the handover procedure. In particular, the invention is aimed at being introduced into the mobility procedures: Baseline Handover (BHO), Conditional HO (CHO), and Dual Active Protocol Stack (DAPS) HO. In addition to the aggregated RAN architecture, the mobility procedures can be applicable to disaggregated RAN architecture, e.g., CU-DU split.

    Abstract: Systems, methods, apparatuses, and computer program products for conditional handover (CHO) execution with network slice service continuity prioritization are provided. A radio resource control (RRC) reconfiguration message sent by a source radio access network (RAN) node to the user equipment (UE) may include, for each CHO configuration, an associated network slice-related priority index. The UE may take this index into account when selecting a suitable cell during CHO recovery. Additionally, or alternatively, the RRC reconfiguration message sent by a source RAN node may include, for each CHO configuration, an associated network slice support information of the candidate target cell. The message may also include network slice remapping information for any network slice associated with one of the candidate target cells. Using the above network slice-related information received from the network, the UE can prioritize the cell to select during CHO recovery in case more than one suitable cell is available.

    Abstract: There are provided measures for network-assisted fallback to contention-based random access. Such measures exemplarily comprise, at a target access point being a target of a handover of a terminal connected to at least one net-receiving work slice from a source access point, receiving a handover request including information on said at least one network slice, selecting, from a plurality of pools of random access channel resources to be used for contention-based random access processing, a first pool of random access channel resources to be used by said terminal upon fallback to contention-based random access during a handover processing, wherein said selecting is based on at least one of network slice related information on terminals in radio resource control idle mode, on terminals in radio resource control inactive mode, and/or on terminals in radio resource control connected mode, and of available random access channel resources, and transmitting a handover request acknowledgement message including handover assistance information indicative of said first pool of random access channel resources.

    Abstract: An apparatus for use by a first communication network control element configured to control a communication connection of at least one communication element in a first network area providing a specific communication capability, the apparatus including processing circuitry, and memory for storing instructions to be executed by the processing circuitry, wherein the memory and the instructions are configured to, with the processing circuitry, cause the apparatus at least: to determine that a communication element communicating in the first network area and using the specific communication capability enters a second network area which does not provide the specific communication capability and that there is a switching of the communication connection to the second network area, and to cause sending of connection switching information related to the switching of the communication connection of the communication element to a second communication network control element.

    Abstract: There are provided measures for feedback on network-assisted fallback to contention-based random access. Such measures exemplarily comprise, at a terminal connected to at least one network slice and being subject to a handover from a source access point to a target access point, receiving a handover command message including handover assistance information indicative of a first pool of random access channel resources to be used by said terminal upon fallback to contention-based random access during a handover processing, selecting first random access channel resources as attempt random access channel resources from said first pool of random access channel resources, attempting random access to said target access point utilizing said attempt random access channel resources, storing, if said attempting random access to said target access point utilizing said attempt random access channel resources is unsuccessful, attempt related information to an attempt failure list, and transmitting, if said attempting random access to said target access point utilizing said attempt random access channel resources is successful, said attempt failure list to said target access point.
