Patent Document ID: 8457140
Application ID: 13357732

Base Claim:
1. A network abstraction gateway (NAG) comprising: at least one abstracted network interface (AN-I) for connectivity with at least one abstracted network (AN) wherein a user has an abstracted endpoint (AE) having a first identity in said abstracted network (AN); at least one communication system interface (CS-I) for connectivity with at least one user's communication system (CS), said communication system interface (CS-I) exposing abstracted endpoint behavior via a second identity in said user's communication system (CS); means (REG) adapted for registering a one-to-one relationship between said first identity and said second identity;means for extracting behavior of said abstracted endpoint (AE), comprising communication features and/or states of said abstracted endpoint (AE); and endpoint abstraction means (AM) adapted for abstracting said abstracted endpoint (AE) in said user's communication system (CS) via an endpoint abstraction (EA) using said second identity, said endpoint abstraction (EA) being responsive to behavior of said abstracted endpoint (AE), being adapted to implement at least one feature and/or state of said user's communication system (CS), and being adapted to bi-directionally map said behavior of said abstracted endpoint (AE) with features and/or states of said user's communication system (CS) via a protocol supported by said user's communication system (CS).

Claim 5:
5. A network abstraction gateway (NAG) according to claim 1 , wherein said at least one feature of said user's communication system comprise one or more of: directory services; a busy lamp feature; attended transfer service; -instant messaging; caller name passing to said abstracted endpoint (AE); a video service; voicemail notification; privacy management; 302 move temporary from said user's communication system; 302 move temporary from said network abstraction gateway (NAG); auto-provisioning of said network abstraction gateway (NAG); call rejection; ad-hoc conferencing; voice continuity service between a WiFi SIP endpoint and a GSM endpoint on a smartphone; unification of a fixed and mobile phone as a single endpoint abstraction; call recording; call restriction management; call privacy management; call reporting; callback on busy and/or callback on no reply; mobile endpoint line supervision by a fixed telephone; fixed and mobile call forking; single number reach; and single voicemail.
