Abstract
A system (1) is disclosed in which a network entity determines whether a radio bearer should be maintained or released for a communications device (2). The communications device (2) establishes the radio bearer via a base station (5) of the communications system (1) and communicates data using the established radio bearer. The communications device (2) determines whether any further data is to be sent or received and/or whether a user-plane connection is required. The communications device (2) 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 a release assistance indication and uplink data, wherein the release assistance indication indicates whether further transmission is expected following transmission of the uplink data,
- wherein the release assistance indication is forwarded from the base station to a Mobility Management Entity (MME), and
- wherein when the release assistance indication indicates that further transmission is expected, a connection associated with the UE is released after the base station transmits, to the UE, downlink data following the base station sending of the release assistance indication.
A method performed by a base station, the method comprising:
- receiving, from a user equipment (UE), a Radio Resource Control (RRC) message which includes a release assistance indication and uplink data, wherein the release assistance indication indicates whether further transmission is expected following transmission of the uplink data;
- and
- forwarding the release assistance indication to a Mobility Management Entity (MME),
- wherein when the release assistance indication indicates that further transmission is expected, a connection associated with the UE is released after the base station transmits, to the UE, downlink data following the base station sending of the release assistance indication.
A user equipment (UE), the UE comprising:
- a memory storing instructions;
- and
- one or more processors configured to execute the instructions to:
- transmit, to a base station, a Radio Resource Control (RRC) uplink message which includes a release assistance indication and uplink data, wherein the release assistance indication indicates whether further transmission is expected following transmission of the uplink data,
- wherein the release assistance indication is forwarded from the base station to a Mobility Management Entity (MME), and
- wherein when the release assistance indication indicates that further transmission is expected, a connection associated with the UE is released after the base station transmits, to the UE, downlink data following the base station sending of the release assistance indication.
A base station in a wireless communication system, the base station comprising:
- a memory storing instructions;
- and
- one or more processors configured to execute the instructions to:
- receive, from a user equipment (UE), a Radio Resource Control (RRC) message which includes a release assistance indication and uplink data, wherein the release assistance indication indicates whether further transmission is expected following transmission of the uplink data;
- and
- forward the parameter to a Mobility Management Entity (MME),
- wherein when the release assistance indication indicates that further transmission is expected, a connection associated with the UE is released after the base station transmits, to the UE, downlink data following the base station sending of the release assistance indication.
