4. The apparatus according to claim 1 , wherein sending the first message comprises:
sending the first message to the primary network device in response to receiving a third indication by a first RRC entity of the apparatus from a second RRC entity of the apparatus, wherein the third indication indicates a configuration failure of the first RRC configuration, the first RRC entity controls a RRC connection between the primary network device and the apparatus, and the second RRC entity controls a RRC connection between the secondary network device and the apparatus.
5. An apparatus comprising:
one or more processors; and
a memory having instructions stored thereon for execution by the one or more processors to cause the apparatus to perform operations comprising:
in response to a first radio resource control (RRC) configuration of a secondary network device being received from the apparatus;
receiving, from a terminal device, a first message for requesting RRC connection reestablishment; and
in response to a second RRC configuration of the secondary network device being received from the secondary network device:
receiving, from the terminal device, a first indication indicating a configuration failure of the second RRC configuration; and
sending, to the secondary network device, a request for updating the second RRC configuration or releasing the secondary network device.
6. The apparatus according to claim 5 , wherein the first indication is comprised in the request.
7. The apparatus according to claim 5 , wherein receiving the first indication from the terminal device comprises:
receiving, from the terminal device, wherein a second message that comprises the first indication.
8. The apparatus according to claim 5 , wherein the first message comprises a second indication indicating a configuration failure of the first RRC configuration.
9. The apparatus according to claim 5 , wherein the operations further comprising:
sending, to the terminal device, a third message for reestablishing a signaling radio bearer (SRB).
10. A method comprising:
in response to a first radio resource control (RRC) configuration of a secondary network device being received from a primary network device;
receiving, by a primary network device from a terminal device, a first message for requesting RRC connection reestablishment; and
in response to a second RRC configuration of the secondary network device being received from the secondary network device:
receiving, by the primary network device from the terminal device, a first indication indicating a configuration failure of the second RRC configuration; and
sending, by the primary network device to the secondary network device, a request for updating the second RRC configuration or releasing the secondary network device.
11. The method according to claim 10 , wherein the first indication is comprised in the request.
12. The method according to claim 10 , wherein receiving, by the primary network device from the terminal device, the first indication comprises:
receiving, by the primary network device from the terminal device, a second message that comprises the first indication.
13. The method according to claim 10 , wherein the first message comprises a second indication indicating a configuration failure of the first RRC configuration.
14. The method according to claim 10 , further comprising:
sending, by the primary network device to the terminal device, a third message for reestablishing a signaling radio bearer (SRB).
15. A method comprising:
receiving, by a terminal device and from a primary network device, a first radio resource control (RRC) configuration of a secondary network device;
sending, by the terminal device to the primary network device, a first message for requesting RRC connection reestablishment in response to the first RRC configuration fails;
receiving, by the terminal device from the secondary network device, a second RRC configuration of the secondary network device;
sending, by the terminal device to the primary network device, a first indication indicating a configuration failure of the second RRC configuration in response to the second RRC configuration fails;
