Abstract
A secondary node (SN) for requesting a master node (MN) to page a user equipment (UE) operating in dual connectivity (DC) with the MN and the SN receives, from a core network (CN), downlink traffic for the UE in an inactive state of a protocol for controlling radio resources, the inactive state being associated with a suspended radio connection between the UE and a radio access network (RAN) (802), and transmits, to the MN, a message that causes the MN to initiate RAN paging of the UE (804).
Claims9
A method performed in a secondary node (SN) in a radio access network (RAN) for communicating with a master node (MN), the method comprising:
- receiving, by processing hardware from a core network (CN), data for the UE in an inactive state of a protocol for controlling radio resources, the inactive state being associated with a suspended radio connection between the UE and the RAN;
- and
- transmitting, by the processing hardware to the MN, the received data.
2-5. (canceled)
A method performed in a master node (MN) for communicating with a user equipment (UE) operating in dual connectivity (DC) with the MN and a secondary node (SN) in a radio access network (RAN), the method comprising:
- receiving, by processing hardware from the SN, data for the UE operating in an inactive state of a protocol for controlling radio resources, the inactive state being associated with a suspended radio connection between the UE and the RAN;
- and
- transmitting, by the processing hardware to the UE, the received data when the UE is in a connected state.
8-10. (canceled)
12-14. (canceled)
A base station in a radio access network (RAN) for communicating with a master node (MN), the base station including processing hardware configured to:
- receive, from a core network (CN), data for the UE in an inactive state of a protocol for controlling radio resources, the inactive state being associated with a suspended radio connection between the UE and the RAN;
- and
- transmit, to the MN, the received data.
