1  ScopeWord‑p. 6
The present document describes several alternatives for the realisation of Mobile Number Portability.
The present document includes information applicable to network operators, service providers, switch and database manufacturers and national regulators.
It is left to operator and implementation decisions which option, or combination of options, is used, taking into account the regulatory and architectural constraints that may prevail. The possible implications of these options on internal node functions and on signalling performance are not covered in the present document.
Normative Annex A of the present document describes the technical realisation of the handling of calls to ported UMTS or GSM mobile subscribers using IN technology.
Normative Annex C of the present document describes the technical realisation of the handling of calls to ported UMTS or GSM mobile subscribers using Signalling Relay technology.
Normative Annex A and Normative Annex C describe alternative solutions. The network operator may choose the solution to be used in his network.
Normative Annex B of the present document describes the technical realisation of the handling of non-call related SCCP signalling for ported UMTS or GSM mobile subscribers using Signalling Relay technology.
The present document does not specify the porting process.

3  Definitions and abbreviationsWord‑p. 7

3.1  Definitions

For the purposes of the present document, the following terms and definitions apply.
donor network:
subscription network from which a number is ported in the porting process. This may or may not be the number range holder network
interrogating network entity:
entity that submits a non-call related signalling message to interrogate the HLR
interrogating network:
network in which the interrogating network entity resides
mobile number portability:
ability for a mobile subscriber to change mobile network subscription within the same country whilst retaining his/her original MSISDN(s). Additional regulatory constraints apply in North America.
mobile number portability information:
an information set relevant to Mobile Number Portability for a mobile subscriber. It may contain one or more of Routeing Number, generic IMSI MSISDN,and Number Portability Status.
network operator:
GSM PLMN operator
non-call related signalling message:
all signalling messages where the MSISDN is used to route the message on SCCP level except MAP SRI without OR parameter set (i.e. SRI_SMS, SRI for SOR, Send_IMSI, CCBS_Request etc)
North American GSM Number portability:
the ability for a subscriber to change subscription between North American GSM networks and other subscription networks within a regulated geographical area within North America.
number portability database:
operational database (used in real time at call set-up) which provides portability information
number portability location register:
internal MAP application terminating function (MATF) in the MNP-SRF network entity with an (unspecified) interface with a NPDB
number portability status:
information indicating the status of number portability for a mobile subscriber. It may be one of: own number ported out, own number not ported out, foreign number ported in, foreign number ported to a foreign network, foreign number not known to be ported
number range holder network:
network to which the number range containing the ported number has been allocated
originating network:
network where the calling party is located
portability domain:
set of GSM PLMNs in a country between which MSISDNs may be ported or a set of North American GSM Mobile networks and other subscription networks within a regulated geographical area within North America
portability network:
a PLMN or ,in North America, a PSTN or an ISDN network
portable number:
E.164 number that can be ported between networks in one nation
ported number:
portable number that has undergone the porting process
ported subscriber:
subscriber of a ported number
porting process:
description of the transfer of a number between network operators
recipient network:
network that receives the number in the porting process. This network becomes the subscription network when the porting process is complete
