Abstract
The embodiments of the present disclosure provide a bearer management apparatus and method, and a communication system. The method comprises: a user equipment (UE) receives an indication message, sent by a base station, for changing a bearer type of a bearer or releasing the bearer under dual connectivity; and changes the bearer type of the bearer or releases the bearer according to the indication message. Through the embodiments of the present disclosure, the UE configured with dual connectivity can seamlessly convert the bearer.
Claims18
A bearer management apparatus configured in a user equipment (UE) configured with dual connectivity, comprising:
- a message receiving unit, configured to receive an indication message, sent by a base station, for changing a bearer type of a bearer or releasing the bearer under dual connectivity;
- and
- a configuring unit, configured to change the bearer type of the bearer or release the bearer according to the indication message.
A bearer management apparatus configured in a user equipment (UE) configured with dual connectivity, comprising:
- a first processing unit, configured to release a Secondary Cell Group (SCG) portion corresponding to a split bearer;
- or, release or deactivate corresponding SCG when all bearers associated with an SCG are released.
A bearer management apparatus configured in a first base station connected to a user equipment (UE) configured with dual connectivity, comprising:
- a detecting unit, configured to detect that a radio connection fails at the UE configured with dual connectivity;
- and
- a sending unit, configured to send to a second base station a request for releasing an associated Secondary Cell Group (SCG) bearer or a split bearer, so that the second base station releases a corresponding bearer.
A bearer management apparatus configured in a second base station connected to a user equipment (UE) configured with dual connectivity, comprising:
- a receiving unit, configured to receive a request, sent by a first base station, for releasing an associated Secondary Cell Group (SCG) bearer or a split bearer;
- and
- a releasing unit, configured to release a corresponding bearer according to the request for releasing.
A communication system, comprising:
- a user equipment (UE) configured with dual connectivity, configured to receive an indication message, sent by a base station, for changing a bearer type of a bearer or releasing the bearer under dual connectivity;
- change the bearer type of the bearer or release the bearer according to the indication message;
- and send a response message to the base station;
- or, configured to release a Secondary Cell Group (SCG) portion corresponding to a split bearer after a Radio Resource Control (RRC) connection reestablishment procedure is triggered;
- or, configured to release or deactivate corresponding SCG when all bearers associated with an SCG are released.
A communication system, comprising:
- a first base station, configured to detect that a radio connection fails at a user equipment (UE) configured with dual connectivity;
- and send to a second base station a request for releasing an associated Secondary Cell Group (SCG) bearer or a split bearer;
- and
- a second base station, configured to receive the request, sent by the first base station, for releasing the associated SCG bearer or the split bearer;
- and release a corresponding bearer according to the request for releasing.
