Multi-connectivity communication method, device, and terminal

A communication apparatus for a terminal, comprising:

• a processor;
• and
• a non-transitory storage medium coupled to the processor and storing executable instructions that, when executed by the processor, cause the terminal to:
• receive, via different logical channels of an air interface between a secondary base station and the terminal, radio resource control (RRC) messages from the secondary base station, the RRC messages comprising a first RRC message generated by an RRC entity of a master base station and a second RRC message generated by an RRC entity of the secondary base station;
• and
• identify, based on the different logical channels, the first RRC message generated by the RRC entity of the master base station, and the second RRC message is generated by the RRC entity of the secondary base station, wherein
• the master base station and the secondary base station use different radio access technologies;
• wherein the instructions, when executed by the processor, further cause the terminal to:
• receive configuration information of a first signaling radio bearer (SRB) from the secondary base station;
• and
• receive configuration information of a second SRB from the secondary base station, the receiving the RRC messages from the secondary base station comprising:
• receiving the first RRC message from the secondary base station using the first SRB;
• and
• receiving the second RRC message from the secondary base station using the second SRB.

A multi-connectivity communication method, comprising:

• receiving, by a secondary base station, a first radio resource control (RRC) message generated by an RRC entity of a master base station;
• generating, by the secondary base station, a second RRC message via an RRC entity of the secondary base station;
• and
• transmitting, by the secondary base station, the first RRC message and the second RRC message to a terminal via two different logical channels of an air interface between the secondary base station and the terminal, wherein the master base station and the secondary base station use different radio access technologies;
• and further comprising:
• establishing, by the secondary base station, first and second signaling radio bearers (SRB) corresponding to the two different logical channels;
• sending, by the secondary base station, configuration information of the first SRB to the terminal;
• and
• sending, by the secondary base station, configuration information of the second SRB to the terminal;
• the transmitting the first RRC message and the second RRC message to the terminal comprising:
• transmitting the first RRC message to the terminal using the first SRB;
• and
• transmitting the second RRC message to the terminal using the second SRB.

A communication apparatus for a secondary base station, the communication apparatus comprising a processor coupled with a non-transitory storage medium storing executable instructions that, when executed by the processor, cause the secondary base station to:

• receive a first radio resource control (RRC) message generated by an RRC entity of a master base station;
• initiate an RRC entity of the secondary base station to generate a second RRC message;
• and
• transmit the first RRC message and the second RRC message to a terminal via two different logical channels of an air interface between the secondary base station and the terminal, wherein the master base station and the secondary base station use different radio access technologies;
• and wherein the executable instructions, when executed by the processor, further cause the secondary base station to:
• establish first and second signaling radio bearers (SRB) corresponding to the two different logical channels;
• send configuration information of the first SRB to the terminal;
• and
• send configuration information of the second SRB to the terminal;
• wherein
• transmitting the first and second RRC messages to the terminal comprises:
• transmitting the first RRC message to the terminal using the first SRB;
• and
• transmitting the second RRC message to the terminal using the second SRB.
