Private Integrated Services Network (PISN)
- Inter-Exchange Signalling Protocol - Private User Mobility (PUM)
- Registration Supplementary Service (QSIG-PUMR)
3rd edition (December 2001)
This Standard specifies the signalling protocol for the support
of the Private User Mobility Registration supplementary service
(SS-PUMR) at the Q reference point between Private Integrated
services Network eXchanges (PINXs) connected together within a
Private Integrated Services Network (PISN).
SS-PUMR is a supplementary service which 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 locations
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. De-registration is used to
inform the PISN that the PUM user is temporarily unable to make
use of the provided services (including the receipt of calls).
SS-PUMR may provide the PUM user with the ability to obtain information
on the current registration sessions (interrogation).
The Q reference point is defined in ECMA-133.
Service specifications are produced in three stages and according
to the method specified in ITU-T Rec. I.130. This Standard contains
the stage 3 specification for the Q reference point and satisfies
the requirements identified by the stage 1 and stage 2 specifications
The signalling protocol for SS-PUMR uses certain aspects of the
generic procedures for the control of supplementary services specified
This Standard also specifies additional signalling protocol requirements
for the support of interactions at the Q reference point between
SS-PUMR and other supplementary services and ANFs.
Additional interactions that have no impact on the signalling
protocol at the Q reference point can be found in the relevant
stage 1 specifications.
This Standard is applicable to PINXs which can interconnect to
form a PISN.
This Standard applies to PUM only within a single PISN.
The protocol defined in this Standard forms part of the PSS1
protocol (informally known as QSIG).
