Abstract: The embodiments of this application disclose an identifier allocation method and apparatus. The method includes: receiving, by a first core network device, a first request from a terminal device; allocating, by the first core network device, a first capability information identifier; and sending, by the first core network device, a first response to the terminal device, where the first response carries the first capability information identifier. Based on this method, the first core network device can allocate a capability information identifier to the terminal device, so that the terminal device can send the capability information identifier instead of capability information to another device, thereby helping save transmission resources for transmitting the capability information.
