The invention discloses a method for establishing a session service in a IP telecommunication network system. In this method, firstly, session service requests for customers to establish business justification and authorization, after connecting the user equipment confirmation and ED equipment, to the user registration database for registration, and all the user dynamic encrypted information sent to the user registration database, for business users to establish a session ED device is proposed the communication resource application, then the initialization work session service, resource status of ED equipment according to the data plane ID examination session service related data in the data plane, plane resources permitting, established between different users session service. Using this method has the ability to control the network session service carrying network resources, to provide quality of service commitment business effectively, and can guarantee the safety of the business network necessary, also has the ability to provide effective traceability, inspection of law enforcement and emergency communication.
