9. A terminal device, including a processor and a memory, wherein:
the memory is configured to store program instructions, and the processor is configured to execute the program instructions stored in the memory, when the program instruction is executed the terminal device is configured to perform the steps of:
sending a first user equipment (UE) capability message to a network device in response to receiving a user equipment UE capability query message from the network device; and
determining that the network device capability is not compatible with the terminal device and that the network device capability is lower than the terminal device;
in response to the determining step, sending a second UE capability message to the network device;
wherein:
the determining step includes determining that a network exception occurs and wherein a second UE capability specification in the second UE capability message is lower than a first UE capability specification in the first UE capability message; and
the sending a second UE capability message to the network device when determining that a network exception occurs comprises sending the second UE capability message to the network device when radio resource control RRC configuration information received from the network device comprises configuration information that is not supported by the terminal device; and
wherein if the first UE capability specification comprises a first category level, a second category level in the second UE capability specification is lower than the first category level.
