Brief History


This Standard is one of a series of standards defining services and signalling procedures applicable to Private
Integrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the
framework of standards for Open Systems Interconnection as defined by ISO/IEC.
This Standard specifies the Private User Mobility Registration (PUMR) supplementary service.
This Standard is based upon the practical experience of ECMA member companies and the results of their active and
continuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national
standardization bodies. It represents a pragmatic and widely based consensus.
There is currently no equivalent service specified by ITU-T or ETSI for public ISDN.
Compared to the 1st Edition of Standard ECMA-281 (published by ECMA in December 1998), the 2nd Edition
(published by ECMA in June 2000) incorporated changes to achieve complete alignment with International Standard
ISO/IEC 17875:2000(E) published by ISO/IEC in April 2000.























Adopted as 3rd Edition of Standard ECMA-281 by the General Assembly of December 2001.

1 Scope
This Standard specifies the Supplementary Service (SS) Private User Mobility Registration (PUMR), which is
applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services
are specified in ECMA-142.
SS-PUMR is a supplementary service that enables a PUM user to register at, or de-register from, any wired or
wireless terminal within the PISN. The ability to register at different wired and wireless terminals in the PISN
at different times enables the PUM user to maintain the provided services (including the ability to make and
receive calls) at different access points.
Supplementary service specifications are produced in three stages, according to the method described in
ITU-T Rec. I.130. This Standard contains the stage 1 and stage 2 specifications of SS-PUMR. The stage 1
specification (clause 6) specifies the general feature principles and capabilities. The stage 2 specification
(clause 7) identifies the Functional Entities involved in the supplementary service and the information flows
between them.
2 Conformance
In order to conform to this Standard, a stage 3 standard shall specify signalling protocols and equipment
behaviour that are capable of being used in a PISN which supports the supplementary service specified in this
Standard. This means that, to claim conformance, a stage 3 standard is required to be adequate for the support
of those aspects of clause 6 (stage 1) and clause 7 (stage 2) which are relevant to the interface or equipment to
which the stage 3 standard applies.
