Abstract: Methods and apparatus, including computer program products, are provided for mobility between networks. In some example embodiments, there may be provided a method. The method may include receiving, at a source base station, a single end marker indication for a flow associated with a user equipment being handed over to a target base station; determining, by the source base station and in response to the received single end marker indication, at least one bearer mapped to the flow; generating for each determined bearer, at least one end of marker indication; and sending, over a forwarding path from the source base station to the target base station, the generated at least one end of marker indication. Related systems, methods, and articles of manufacture are also described.

Abstract: Methods and apparatus, including computer program products, are provided for mobility. In some example embodiments, there may be provided a method that includes determining whether to handover to a target base station, the determining based on whether a security level of the target base station satisfies a security threshold; enabling a relocation of a packet data convergence protocol entity to enable ciphering a tunnel to a user equipment, when the security level satisfies the security threshold; and inhibiting the relocation of the packet data convergence protocol entity to inhibit ciphering a tunnel to the user equipment, when the security level does not satisfy the security threshold. Related systems, methods, and articles of manufacture are also described.

Abstract: The present disclosure relates to techniques that enable an efficient Radio Link Monitoring (RLM) for a User Equipment (UE) in a multi Transmitter Receiver Point (mTRP) scenario. For this purpose, a serving cell of a serving Distributed Unit (DU) of a disaggregated network node and at least one non-serving (or stand-by) cell of a non-serving DU of the disaggregated network node are configured fora UE. Then, the UE is informed of beams used for the serving and non-serving cells. The UE performs the RLM over the serving cell by using the beams of the serving cell. Whenever there is an Radio Link (RL) quality degradation (which may potentially lead to an RL Failure (RLF)) detected in the serving cell, the UE may initiate switching of the RLM from the serving cell to one of the non-serving cells by transmitting a corresponding request to the serving DU.

Abstract: Example embodiments of the present disclosure relate to QoE measurement collection in non-connected State. In an example method, a terminal device receives, from an access network device, a quality of experience (QoE) measurement collection (QMC) procedure configuration indicating whether a QMC procedure is to be continued when the terminal device enters into a non-connected state. Then, the terminal device logs, in a logging buffer, QMC logging data of the QMC procedure performed at the terminal device in the non-connected state based on determining that the QMC procedure configuration indicates that the QMC procedure is to be continued when the terminal device enters into the non-connected state. In this way, QMC data collected in a non-connected state can be stored in the logging buffer so that the needed QMC data collected during non-connected state can be maintained.

Abstract: The present disclosure relates generally to the field of wireless communications, and particularly to a network-based mechanism for early detection of failures during fast Master Cell Group (MCG) recovery. For this purpose, a Secondary Node (SN) may determine that a User Equipment (UE) experiencing an MCG failure is unable to receive a command for handover (HO) from a source MCG to a target MCG. This determination may be based on the occurrence of at least one of the following events: (i) a recovery timer (e.g., T316 timer) has expired at the UE, and (ii) a number of retransmissions performed by the SN to deliver the HO command to the UE reaches a threshold before the recovery timer expires. The SN may then report the fast MCG recovery failure to a Master Node (MN), with the indication that event (i) and/or event (ii) has occurred. This may allow the MN to take appropriate actions (e.g., properly correct the recovery timer), which may in turn decrease the interruption time caused by similar MCG failures and save network resources in the future.
