Communication method and related device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and a related device. Background Wireless networks have been under rapid construction to meet the increasing traffic demands of people. As the network scale is built larger, the power consumption of the network continues to increase. For example, in the fifth generation (5th Generation,5G) mobile communication technology, the number of active antenna processing units (ACTIVE ANTENNA unit, AAU) is increased significantly, the power consumption is doubled, for example, in the 5G era, a higher data transmission rate and a larger traffic are required, so that there is more transmission bandwidth, resulting in an increase in power consumption of the network device side, for example, millimeter waves, terahertz, etc. are applied to the communication field, resulting in a denser site deployment of the network device side, and thus, the power consumption of the network device side is also increased. Currently, communication systems support a support tracking area (TRACKING AREA, TA) that includes one or more RNAs that include one or more cells (cells) and a radio access network notification area (RAN-based notification area, RNA). When the terminal device is in a radio resource control (radio resource control, RRC) IDLE state (rrc_idle), the network device needs to send a paging (paging) message to all TAs in a tracking area identity (TRACKING AREA IDENTIFIER, TAI) list to which the terminal device belongs in order to find the terminal device. And for the terminal equipment in the RRC INACTIVE state (rrc_inactive), the network equipment sends a paging message to all cells included in the RNA in which the cell where the terminal equipment resides. How to reduce the paging message overhead of a network device is a problem to be solved at present.

Wherein the first update reason is related to an update event satisfied by the terminal device, and the update event satisfied by the terminal device is determined based on parameter information of the terminal device and/or parameter information of the network device. In the above technical solution, the first indication information may indicate a specific update reason, where the update reason is related to whether the terminal device moves out of the first area. So that the first network device determines whether to update the relevant information of the terminal device according to the update reason, and reduces the paging message overhead of the first network device to the terminal device. With reference to the first aspect, in a possible implementation manner of the first aspect, the first update reason specifically indicates any one of the first network device updates the identification information of the first area where the terminal device is located, or the first network device updates the identification information of the first area where the terminal device is located, and the
