Abstract: Embodiments of this application provide a communication method and apparatus. The apparatus includes a receiving module and a sending module. When the receiving module receives a user equipment UE capability query message sent by a network device, the sending module sends a first UE capability message (including a first UE capability specification) to the network device, and when determining that a network exception occurs, sends a second UE capability message (including a second UE capability specification that is lower than the first UE capability specification) to the network device. This helps implement mutual compatibility between the terminal device and the network device, thereby ensuring that a communication link can be quickly established between the terminal device and the network device. In this way, a user can normally use the terminal device, and the terminal device can keep using a high-standard network as much as possible, thereby improving user experience.
