Abstract :
In future, user-centric cognitive communication services under convergent environments will take appropriate adaptations to enhance service experience according to user´s needs and service contexts. By analyzing constituent elements of session and connection between them, a novel Adaptive Session Description Model-ASDM, is proposed, consisting of a three-layer session structure: node session, terminal session and service session. This model gives the concept of session isomorphism and corresponding judge conditions. This paper compares the ASDM with other existent model, and takes a real adaptive session scenario as an example to validate practicability and correctness of this model.
