Abstract
A communication device for handling communications in a dual connectivity comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The storage device stores, and the processing circuit is configured to execute instructions of establishing a first signaling radio bearer (SRB) with a master base station (MBS); establishing a second SRB with a secondary BS (SBS); receiving a first radio resource control (RRC) message comprising a first configuration, on the first SRB from the MBS; receiving a second RRC message comprising a second configuration, on the second SRB from the SBS; and applying the first configuration and ignoring the second configuration, when detecting a conflict between the first configuration and the second configuration.
Claims17
A communication device for handling communications in a dual connectivity, comprising:
- a storage device;
- and
- a processing circuit, coupled to the storage device, wherein the storage device stores, and the processing circuit is configured to execute instructions of:
- establishing a first signaling radio bearer (SRB) with a master base station (MBS) in a radio resource control (RRC) connection establishment procedure;
- establishing a second SRB with a secondary BS (SBS) in a RRC connection reconfiguration procedure;
- transmitting a first RRC response message on the first SRB in response to a first RRC message, when receiving the first RRC message on the first SRB;
- receiving a third RRC message comprising the first RRC message on the first SRB from the MBS, wherein the MBS receives the first RRC message from the SBS;
- transmitting a third RRC response message comprising the first RRC response message on the first SRB to the MBS in response to the third RRC message comprising the first RRC message;
- and
- transmitting a second RRC response message on the second SRB in response to a second RRC message, when receiving the second RRC message on the second SRB;
- wherein the first RRC message configures the second SRB to the communication device;
- wherein the second RRC message changes a primary SCell of the SBS.
A method for handling communications in a dual connectivity for a communication device, comprising:
- establishing a first signaling radio bearer (SRB) with a master base station (MBS);
- establishing a second SRB with a secondary BS (SBS);
- receiving a first radio resource control (RRC) message on the first SRB from the MBS, wherein the MBS receives the first RRC message from the SBS;
- transmitting the first RRC response message on the first SRB to the MBS in response to the first RRC message;
- receiving a third RRC message including the first RRC message on the first SRB;
- transmitting a third RRC response message including a first RRC response message on the first SRB, in response to the third RRC message including the first RRC message;
- and
- transmitting a second RRC response message on the second SRB in response to a second RRC message, when receiving the second RRC message on the second SRB;
- wherein the first RRC response message responds to the first RRC message;
- wherein the first RRC message configures the second SRB to the communication device;
- wherein the second RRC message changes a primary SCell of the SBS.
A network for handling communications in a dual connectivity, comprising:
- a master base station (MBS) comprising
- a storage device;
- and
- a processing circuit, coupled to the storage device,
- a second base station (SBS) comprising
- a storage device;
- and
- a processing circuit, coupled to the storage device,
- wherein the storage device of the MBS stores, and the processing circuit of the MBS is configured to execute instructions of:
- establishing a first signaling radio bearer (SRB) with a user equipment (UE) in a RRC connection establishment procedure;
- transmitting a first radio resource control (RRC) message in a RRC connection reconfiguration procedure configuring a second SRB for exchanging RRC messages between the UE and the SBS to the UE;
- receiving a first RRC response message on the first SRB in response to the first RRC message received by the UE;
- transmitting a third RRC message comprising the first RRC message on the first SRB to the UE, wherein the MBS receives the first RRC message from the SBS;
- and
- receiving a third RRC response message comprising the first RRC response message on the first SRB from the UE in response to the third RRC message comprising the first RRC message;
- and
- wherein the storage device of the SBS stores, and the processing circuit of the SBS is configured to execute instructions of:
- establishing the second SRB with the UE;
- transmitting a second RRC message on the second SRB to the UE;
- and
- receiving a second RRC response message on the second SRB in response to the second RRC message received by the UE;
- wherein the second RRC message changes a primary SCell of the SBS.
