  • Patent number: 11902843
    Abstract: A method and a wireless device are provided for handling handover in a wireless network from a source cell to a target cell when the device has obtained and stored a handover configuration for at least one target cell X. Upon detecting a communication failure, the wireless device performs cell selection and initiates handover to one of the target cell(s) X when that cell was selected, by applying the stored handover configuration of the selected cell. When none of the target cell(s) X was selected in the cell selection, the wireless device initiates an RRC re-establishment procedure.

  • Patent number: 11895545
    Abstract: Systems, methods and apparatus are disclosed for handling conditional handover configurations by wireless devices and network nodes. An example method performed by a wireless device includes receiving and storing one or more conditional handover configurations associated with a target cell candidate. The wireless device transitions from a connected state to a sleeping state, where the transition includes discarding the conditional handover configurations. The wireless device releases resources associated with the conditional handover configurations and performs clean up actions relating to conditional handover. An example method performed by a network node includes providing, to a user equipment, one or more conditional handover configurations that are associated with a target cell candidate. The network node transmits, to the user equipment, a message to transition from a connected state to a sleeping state. After transmitting the message, the network node discards the conditional handover configurations.

  • Patent number: 11877332
    Abstract: Systems, methods and apparatus are disclosed for user equipment and network nodes. An example method performed by a user equipment (UE) includes the UE detecting a failure relating to a connection between the UE and a Master Cell Group (MCG). The UE provides, to a master node via a Secondary Cell Group, SCG, a first message relating to the detected failure. The UE receives, from the master node via the SCG, a second message indicating to the UE to perform a connection reconfiguration. An example method performed by the master node includes the master node receiving, from the UE via the SCG, the first message including information relating to the detected failure of the connection between the UE and the MCG. The master node determines, based on the first message and a user equipment context, to perform a connection reconfiguration. The master node provides, to the UE via the SCG, the second message indicating to perform the connection reconfiguration.

  • Patent number: 11864035
    Abstract: A method for a handover procedure comprises establishing a connection with a source network node of a first core network; receiving a radio resource control (RRC) message including an information element, wherein the information element indicates a second core network associated with a target network node; applying security parameters based on the second core network indicated in the information element; and performing a handover toward the target network node using the applied security parameters. The method provides an indication in RRC connection reconfiguration procedure to indicate the UE the core network of the target network node, so that the UE may recognize that this is an inter-system handover and apply corresponding security parameters for performing the handover without additional signaling.

  • Patent number: 11638191
    Abstract: Methods and apparatus are provided for handover of a UE from a source node connected to a first core network to a target node connected to a second core network. The UE receives, from the source node, a mobility command including an indication of the radio access technology (RAT) used by the target node and a message container containing configuration information for the target node. The UE further determines, based on the indication of the RAT used by the target node, whether to treat the handover as an inter-RAT handover or as an intra-RAT handover with a core network change, and performs a radio resource control procedure for one of an inter-RAT handover or an intra-RAT handover with a core network change based on the determination.
