Abstract
A system is disclosed in which a network entity determines whether a radio bearer should be maintained or released for a communications device. The communications device establishes the radio bearer via a base station of the communications system and communicates data using the established radio bearer. The communications device determines whether any further data is to be sent or received and/or whether a user-plane connection is required. The communications device then provides information to the network entity identifying a result of said determination for use in determining whether the radio bearer should be maintained or released.
Claims12
A method performed by a user equipment (UE), the method comprising:
- transmitting, to a base station, a Radio Resource Control (RRC) message which includes an assistance information indicating whether further transmission is expected following transmission of an uplink data, and
- receiving, from the base station, downlink data after the assistance information is forwarded from the base station to a core network node,
- wherein in a case where the assistance information indicates that further transmission is expected, a connection associated with the UE is released after receiving the downlink data from base station.
A method performed by a base station, the method comprising:
- receiving, from a user equipment (UE), a Radio Resource Control (RRC) message which includes an assistance information indicating whether further transmission is expected following transmission of an uplink data;
- and
- forwarding the assistance information to a core network node, and
- transmitting, to the UE, downlink data after the forwarding,
- wherein in a case where the assistance information indicates that further transmission is expected, a connection associated with the UE is released after the transmitting the downlink data to the UE.
A user equipment (UE) comprising:
- a transmitter configured to transmit, to a base station, a Radio Resource Control (RRC) message which includes an assistance information indicating whether further transmission is expected following transmission of an uplink data, and
- a receiver configured to receive, from the base station, downlink data after the assistance information is forwarded from the base station to a core network node,
- wherein in a case where the assistance information indicates that further transmission is expected, a connection associated with the UE is released after the receiver receives, from base station, the downlink data.
A base station comprising:
- a receiver configured to receive, from a user equipment (UE), a Radio Resource Control (RRC) message which includes an assistance information indicating whether further transmission is expected following transmission of an uplink data;
- and
- a transmitter configured to:
- forward the assistance information to a core network node, and
- transmit, to the UE, downlink data after forwarding the
- assistance information to the core network node,
- wherein in a case where the assistance information indicates that further transmission is expected, a connection associated with the UE is released after the transmitter transmits, to the UE, the downlink data.
