Session integration service over multiple devices

Abstract

SUMMARYOne of the most important research subjects in session initiation protocol (SIP) is mobility management. Session mobility is a key issue in SIP mobility management. Session mobility is an advanced feature that maintains an ongoing media session from one device to another. In this paper, we consider the issue of session mobility and propose a complete integrated solution, referred to as 'session integration service', to transfer an ongoing media session over multiple devices. To provide flexibility in session mobility, three new agent states are introduced based on the user agent definition. They consist of session manager, session user, and free node. This paper also proposes two split session integration methods for session integration service based on these three agents. The proposed method provides session mobility flexibility and allows the user the ability to transfer, split, and retrieve a session over multiple devices. Moreover, the split session can be integrated in any devices. To ensure session mobility over multiple devices, the session integration service will be implemented through a modification of the open source project 'SIP-communicator'.

An improved password‐based authentication scheme for session initiation protocol using smart cards without verification table

“…The SIP was developed by the Internet Engineering Task Force [23] in 1996. SIP is an application layer signaling protocol for creating, modifying, and terminating multimedia sessions among one or more participants (e.g., [24][25][26][27][28][29][30]). Various authentication schemes especially using password have been proposed to provide security for SIP (e.g., [31][32][33][34][35][36][37][38][39][40][41][42][43]).…”

An anonymous and untraceable password‐based authentication scheme for session initiation protocol using smart cards

“…With the widespread application of the voice over IP (VoIP) in Internet [1][2][3][4] and mobility management [5][6][7][8], the security of VoIP is becoming increasingly important [9]. When a user wants to access a VoIP service, he or she has to perform an authentication process from the remote server.…”
