摘要： 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.

摘要： A UE and a method for resuming a radio connection in a communications network comprising a first RAT and a different second RAT. The UE operates in a first cell served by the first RAT. When a connection with the first cell is suspended, the UE performs a re-selection to a second cell served by the second RAT, and triggers RRC resume in the second cell. The UE receives a first set of parameters associated with the first cell, which first set comprises at least one parameter identifying the UE or the first cell. Further, the UE receives a second set of parameters associated with the second cell, which second set comprises at least one parameter identifying the UE or the second cell. The UE determines a security token based on the first and second sets, and transmits the security token to the second cell.

摘要： According to certain embodiments, disclosed is a method in a master node (MN) for minimizing user plane interruption delay. The method includes transmitting a handover request message to a secondary node (SN), receiving a handover request acknowledge message from the SN, and transmitting a reconfiguration instruction to a wireless device operating in dual connectivity with the MN and the SN. The reconfiguration instruction may include a new configuration wherein the SN is a target SN and an indication of a trigger used to switch to the new configuration.

摘要： A wireless device is configured to operate in first and second access networks. The first and second access networks respectively provide access to first and second core networks of different types. A first wireless communication network includes the first access network and the first core network. A second wireless communication network includes the second access network and the second core network. The wireless device is configured to receive, from the first access network, control signaling indicating that the wireless device is to suspend a connection with the first access network and indicating a notification area within which the wireless device is allowed to move without notifying either the first and second wireless communication networks. The control signaling indicates the notification area includes one or more areas of the first wireless communication network and one or more areas of the second wireless communication network.

摘要： Systems, methods, and apparatus for handling messages from network nodes of a wireless communications system are disclosed. An example method performed by a terminal includes receiving a message from a network node. The terminal determines that the message contains a reconfigurationWithSync field and that security is not activated when the message is received. Responsive to the determining, the terminal prevents triggering of a handover operation.

摘要： A method is provided by a wireless device for performing reconfiguration and/or resumption of a radio resource control, RRC, connections while operating in a Multi-RAT Dual Connectivity, MR-DC or standalone New Radio, NR, environment. The method includes suspending the wireless device to an inactive mode. The method further includes resuming operation of the wireless device from the inactive mode. The method further includes receiving an indication to perform one of: releasing a master cell group and perform a configuration on at least one of one or more radio bearer configurations and a secondary cell group configuration; or releasing configurations for a master cell group and a secondary cell group and perform the configuration on one or more radio bearer configurations.

摘要： A method in a network node includes obtaining a first identifier associated with resuming an inactive connection between a wireless device and a network. The method further includes receiving a second identifier from the wireless device. The second identifier is either the same as the first identifier or is associated with the first identifier. The method further including determining a location indicator based on the second identifier. The location indicator indicates a location within the network from which to obtain information associated with the connection. The method further including obtaining the information associated with the connection from the location indicated by the location indicator. The method further including using the information associated with the connection to facilitate resuming the connection between the wireless device and the network.

摘要： 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.

摘要： According to certain embodiments, a target network node for communicating with a user equipment (UE) that was previously in communication with a source network node, comprises an interface operably coupled to processing circuitry. The interface is configured to receive a connection resume request from the user equipment, wherein the connection resume request comprises a resume identification associated with the source network node. The processing circuitry is configured to determine that the UE was previously in communication with the source network node. The interface is further configured to transmit the connection resume request to the source network node, receive a radio resource control (RRC) response from the source network node, and forward the RRC response to the UE.
