Abstract: A communication method and a communications apparatus are disclosed. The method is performed by a control plane function entity and includes: obtaining a correspondence between address information of a user plane function entity and a user plane capability supported by the user plane function entity; receiving a request message from an application server, where the request message is used to request to establish a session for a first service and includes service information of the first service, and the service information includes at least one of broadcast area information and service type information; determining address information of a target user plane function entity based on the correspondence and the service information; and establishing a session connection to the target user plane function entity based on the address information.

Abstract: A payment system and method of IC card and a multi-application IC card as well as payment terminal are proposed in the present invention. The terminal and the IC card perform off-line data authentication using an asymmetric key algorithm during an off-line transaction, and if the transaction is not approved in manner of off-line, the terminal and the IC card performs an on-line transaction via a host. Therefore, the payment system and method of IC card and the multi-application IC card as well as payment terminal disclosed in the present invention can be used both in machinery without on-line transaction environment and in standard merchant machinery with on-line transaction environment.
