Abstract

Private Integrated Services Networks (PISN) may offer special services to their subscribers, e.g. the call completion supplementary services. These can be CCBS (Call Completion to Busy Subscriber) and CCNR (Call Completion on No Reply). CCBS enables a calling User A, encountering a busy destination User B, to complete the call when User B is not busy anymore, without having to make a new call attempt. CCNR enables a calling User A, encountering an alerted but not answering destination User B, to complete the call when User B is not busy anymore after a period of activity, without having to make a new call attempt. These supplementary services have to be activated for every call. This can be dissatisfying and time consuming. In this invention a new way of activation/deactivation of these supplementary services is suggested, which could be named CCBSe (CCBS enhanced) or CCNRe (CCNR enhanced). These two enhancements use the basic functions of CCBS / CCNR (e.g. via Time Division Multiplexing TDM, Internet Protocol IP, Voice/Video over Digital Subscriber Line VoDSL, Session Initiation Protocol SIP, etc.) with the addition of an automatic activation (and optionally deactivation) method.

CCBS / CCNR Enhanced

Idea: George Stylianopoulos; GR-Athens

Private Integrated Services Networks (PISN) may offer special services to their subscribers, e.g. the call completion supplementary services. These can be CCBS (Call Completion to Busy Subscriber) and CCNR (Call Completion on No Reply). CCBS enables a calling User A, encountering a busy destination User B, to complete the call when User B is not busy anymore, without having to make a new call attempt. CCNR enables a calling User A, encountering an alerted but not answering destination User B, to complete the call when User B is not busy anymore after a period of activity, without having to make a new call attempt. These supplementary services have to be activated for every call. This can be dissatisfying and time consuming.

In this invention a new way of activation/deactivation of these supplementary services is suggested, which could be named CCBSe (CCBS enhanced) or CCNRe (CCNR enhanced). These two enhancements use the basic functions of CCBS / CCNR (e.g. via Time Division Multiplexing TDM, Internet Protocol IP, Voice/Video over Digital Subscriber Line VoDSL, Session Initiation Protocol SIP, etc.) with the addition of an automatic activation (and optionally deactivation) method.

In case a CCBSe supported user initiates a call and if it is ascertained that the target user is busy, a normal CCBS is automatically initiated without any activation action performed by the assisted user side. In case a CCNRe supported user initiates a call and if the target user does not...
