Abstract
A first base station receives from a second base station: a cell identifier of a cell of the second base station; and a second radio access network (RAN) area identifier of the cell. A packet for a wireless device in a radio resource control (RRC) inactive state is received. A RAN paging message is sent to the second base station in response to receiving the packet. The RAN paging message is based on a first RAN area identifier of the first base station being identical to the second RAN area identifier.
Claims20
A method by a first base station comprising:
- receiving, from a second base station, cell related information including one or more second cell identifiers of one or more cells supported by the second base station;
- identifying a packet for a wireless device in a radio resource control (RRC) inactive state supporting a radio access network (RAN) paging;
- and
- transmitting, to the second base station, in response to identifying the packet, a RAN paging message based on a first RAN area identifier of one or more cells supported by the first base station and a second RAN area identifier of the one or more cells supported by the second base station.
A method by a second base station comprising:
- transmitting, to a first base station, cell related information including one or more second cell identifiers of one or more cells supported by the second base station;
- and
- receiving, from the first base station, a radio access network (RAN) paging message for a wireless device based on a first RAN area identifier of one or more cells supported by the first base station and a second RAN area identifier of the one or more cells supported by the second base station,
- wherein the wireless device is in a radio resource control (RRC) inactive state supporting a RAN paging.
An apparatus by a first base station in a communication, the apparatus comprising:
- a transceiver configured to transmit and receive data;
- and
- at least one processor configured to:
- control to the transceiver to receive, from a second base station, cell related information including one or more second cell identifiers of one or more cells supported by the second base station,
- identify a packet for a wireless device in a radio resource control (RRC) inactive state supporting a radio access network (RAN) paging, and
- control to the transceiver to transmit, to the second base station, in response to identifying the packet, a RAN paging message based on a first RAN area identifier of one or more cells supported by the first base station and a second RAN area identifier of the one or more cells supported by the second base station.
