Service access method, terminal device, server, and routing node

A service access method, applied to a service authorization server, comprising:

• receiving a service authorization request for a target application sent by a terminal device;
• determining, according to a local access regulation and control policy configured for the target application, whether to allow the terminal device to perform service access on the target application;
• and
• configuring, in a case that the terminal device is allowed to perform the service access on the target application, a service authorization certificate and a time limit of the service authorization certificate for the terminal device, such that the terminal device sends a service access request for the target application to a routing node, wherein the service access request carries the service authorization certificate and the time limit, and the service authorization certificate and the time limit are used by the routing node for performing service authorization credibility verification, and in response to that the service authorization credibility verification is passed, the service access request is forwarded to an application server of the target application.

A service access method, applied to a routing node, comprising:

• receiving a service access request sent by a terminal device, wherein the service access request carries a service authorization certificate and a time limit of the service authorization certificate, and the service authorization certificate and the time limit are configured by a service authorization server for the terminal device;
• performing, based on the service authorization certificate and the time limit in the service access request, service authorization credibility verification;
• and
• forwarding, in a case that the service authorization credibility verification is passed, the service access request to an application server of a target application, such that the application server establishes a service connection for the terminal device.
