Study on a session description model for cognitive communication services adaptation in converged network

摘要

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.
