Provided in the present application are a communication method and a related apparatus, which are applied to the technical field of communications. In the embodiments of the present application, area partitioning can be performed to determine a distribution mode of first
system messages, and then different first
system messages are configured on the basis of the area partitioning, such that a terminal will also receive corresponding first
system messages on the basis of different areas. Configurations for areas with different access requirements do not need to be centrally carried within the first system messages, such that areas with different access requirements can have different configurations, for example, sub-
satellite areas / areas with low access requirements can be configured with fewer
access time-frequency resources or with fewer
paging repetitions, while edge areas / areas with high access requirements can be configured with more
access time-frequency resources or with more
paging repetitions. In this way, system messages for different areas can be independently configured, thereby improving the flexibility of allocating resources.
