Abstract :
This paper presents personalized services (policies) specified in extended call processing language (CPL) and their mobility. With three-layered service architecture, both personalized services and their mobility for call-processing and presence are described in the session initiation protocol (SIP) environment. To provide the security for service mobility via the mobility of CPL policies, a new security scheme based on identity based encryption (IBE) is presented to protect private personal policies in an un-trusted host environment.
