after the releasing or deactivating the first RRC connection, establishing or resuming the second RRC connection with the second subscriber identity to a second access network device; and
sending first indication information to the second access network device, wherein the first indication information indicates the second access network device to accelerate release or deactivation of the second RRC connection.
8. A wireless communication method, comprising:
receiving a first message from a terminal device, wherein the first message requests at least one of establishment or resumption of a second radio resource control (RRC) connection with a second subscriber identity, wherein the first message comprises auxiliary information, wherein the auxiliary information indicates to release or deactivate a first RRC connection, wherein the first RRC connection is a connection established by the terminal device with a first subscriber identity, and wherein the second RRC connection is a connection established by the terminal device with the second subscriber identity;
determining, based on the auxiliary information, to release or deactivate the first RRC connection; and
sending a second message to the terminal device, wherein the second message indicates to release or deactivate the first RRC connection, and wherein the terminal device is in an RRC connected state with the first subscriber identity when the terminal device sends the first message, and wherein the terminal device is in an RRC idle state or an RRC deactivated state with the second subscriber identity when the second message is sent.
9. The wireless communication method according to claim 8 , wherein the auxiliary information comprises at least one of a reason for establishing or resuming the second RRC connection, a type of the second RRC connection, service type information or service priority information of the second RRC connection, an expected duration of the second RRC connection; or capability information indicating whether the terminal device supports deactivation of the first RRC connection.
10. The wireless communication method according to claim 8 , further comprising determining, after the first RRC connection is released or deactivated, whether to initiate paging for the first subscriber identity based on the auxiliary information.
11. The wireless communication method according to claim 8 , wherein the second message comprises delay indication information, and wherein the delay indication information indicates to at least one of delay releasing the first RRC connection or delay deactivating the first RRC connection.
12. The wireless communication method according to claim 8 , wherein the second message comprises delay duration information, and wherein the delay duration information indicates a duration of at least one of delaying releasing the first RRC connection or delaying deactivating the first RRC connection.
13. The wireless communication method according to claim 8 , wherein the second message comprises return indication information, and wherein the return indication information indicates to the terminal device to trigger at least one of establishment or resumption of the first RRC connection after the second RRC connection is released or deactivated.
14. The wireless communication method according to claim 8 , wherein the second message comprises return duration information, and wherein the return duration information indicates to the terminal device to establish or resume the first RRC connection within the return duration.
15. An apparatus, comprising:
one or more processors; and
one or more memories coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions including instructions to:
send, with a first subscriber identity, a first message to a first access network device, wherein the apparatus supports the first subscriber identity and a second subscriber identity, wherein the first message requests at least one of establishment or resumption of a second radio resource control (RRC) connection with the second subscriber identity, wherein the first message comprises auxiliary information, wherein the auxiliary information indicates to the first access network device to determine to release or deactivate a first RRC connection, wherein the first RRC connection is a connection established with the first subscriber identity, and wherein the second RRC connection is a connection established with the second subscriber identity; and
