In the method, a Visit Policy and Charging Rules Function (V-PCRF) receives an S9 session establishment triggering message from a Home Policy and Charging Rules Function (H-PCRF), wherein the S9 session establishment triggering message is used for triggering establishment of an S9 session and a first S9 sub-session, and the first S9 sub-session is used for policy control of Evolved Packet Core (EPC)-routed traffic; the V-PCRF determines whether the S9 session has been or is being established; and when it is determined that the S9 session has been or is being established, the V-PCRF indicates to the H-PCRF that the S9 session has been or is being established. Through the solution, conflict is avoided in the process of establishing the S9 sub-session in the related art and the stability of the system is improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus and system for establishing session","description":"Provided are a method, an apparatus and a system for establishing a session.
