1. A network slice selection method, comprising:
obtaining, by a first network slice selection apparatus, a service request message, wherein the service request message is to initiate a service request for a service of a tenant, and the service request message includes service requirement information of the service;
determining, by the first network slice selection apparatus, a network requirement of the service based on the service requirement information of the service included in the service request message;
determining, by the first network slice selection apparatus, priority information based on the network requirement of the service; and
sending, by the first network slice selection apparatus, a network slice request message to a second network slice selection apparatus based on the service request message, wherein
the network slice request message carries the priority information and information about the network requirement of the service, and
the priority information indicates at least one of a priority of the tenant or a priority of the service,

the priority information and the information about the network requirement of the service are usable by the second network slice selection apparatus to select a network slice for the service of the tenant, to cause the service to be provided over the selected network slice to the tenant, wherein selecting the network slice for the service of the tenant comprises:
in response to the priority information indicating the service having a higher priority, carrying the service having the higher priority independently in one network slice, and
in response to the priority information indicating the service having a lower priority, carrying the service having the lower priority in a shared network slice in which the service having the lower priority is jointly carried with another service, and

the priority information is usable by a further apparatus, to which the second network slice selection apparatus sends a network function configuration message including the priority information, to select a network function to be accessed for the service of the tenant.
