Method and apparatus for establishing secondary connection

An apparatus for establishing a secondary connection, comprising:

• a memory, a processor, a communication interface, and an instruction stored on the memory and operable on the processor,
• wherein the processor, when running the instruction, is configured to:
• acquire secondary network access capability information of a terminal device, wherein the secondary network access capability information is used to indicate a capability for the terminal device to access a secondary access network device;
• control the communication interface to send a secondary connection addition request message to a first secondary access network device, wherein the secondary connection addition request message is used to request addition of the first secondary access network device as a network device for transmitting data, and the secondary connection addition request message comprises the secondary network access capability information;
• and
• control the communication interface to receive a confirmation message of the secondary connection addition request message sent by the first secondary access network device, wherein the confirmation message of the secondary connection addition request message comprises first configuration information, and the first configuration information is used to establish the secondary connection between the first secondary access network device and the terminal device;
• wherein the secondary connection addition request message further comprises second configuration information, wherein the second configuration information is configuration information of the secondary connection that has been established by the terminal device.

• a memory, a processor, a communication interface, and an instruction stored on the memory and operable on the processor,
• wherein the processor, when running the instruction, is configured to:
• control the communication interface to receive a secondary connection addition request message sent by a primary access network device, wherein the secondary connection addition request message is used to request addition of the first secondary access network device as a network device for transmitting data, and the secondary connection addition request message comprises secondary network access capability information, wherein the secondary network access capability information is used to indicate a capability for a terminal device to access a secondary access network device;
• generate first configuration information according to the secondary network access capability information, wherein the first configuration information is used to establish the secondary connection between the first secondary access network device and the terminal device;
• and
• control the communication interface to send a confirmation message of the secondary connection addition request message to the primary access network device, wherein the confirmation message of the secondary connection addition request message comprises the first configuration information;
