Resuming a radio connection in multi- radio dual connectivity

A base station for resuming a suspended radio connection between a user equipment (UE) and a radio access network (RAN), the base station comprising processing hardware configured to:

• receive a request to resume the suspended radio connection for the UE operating in dual connectivity (DC) with a first master node (MN) and a first secondary node (SN);
• cause a previous configuration related to at least one of the first MN and the first SN to be released;
• and
• transmit, to the UE, a command to resume the suspended radio connection, the command including new configuration related to at least one of the first MN, a second MN, the first SN, or a second SN.

A method performed in a user equipment (UE) for resuming a radio connection with a radio access network (RAN), suspended in dual connectivity (DC) operation, the method comprising:

• operating in DC with a first master node (MN) and a first secondary node (SN);
• transitioning, by processing hardware, from a connected state to an inactive state associated with a protocol for controlling radio resources, including suspending the radio connection;
• and
• while in the inactive state, receiving a command to resume the suspended radio connection from the first MN or a second MN, the command including new configuration related to at least one of the first MN, the second MN, the first SN, or a second SN.
