02.663GPPService descriptionStage 1Support of Mobile Number Portability (MNP)TS
The present document defines the stage one description of the Support of Mobile Number Portability between GSM networks in the same country as well as PCS-1900 cross-sector portability (i.e., number portability between fixed and PCS-1900 mobile networks). Stage one is an overall service description, primarily from the service subscriber’s and user’s points of view, but does not deal with the details of the human interface itself.
The present document is in response to a study mandate agreed between the European Commission and ETSI under order voucher ESTI/97/M-251 and the mandate by the US Federal Communications Commission for Service Provider Portability in North America.
Mobile Number Portability (MNP) is applicable only to those telecommunication services identified by an MSISDN.
The present document includes information applicable to network operators, service providers and terminal, switch and database manufacturers.
The present document contains the core requirements for the Support of Mobile Number Portability between GSM network operators in the same country as well as PCS-1900 cross-sector portability which are sufficient to provide a complete service.
Other cross-sector portability options (e.g. number portability between fixed and mobile networks) are outside the scope of the present document. It is highly desirable however, that technical solutions for MNP should be sufficiently flexible to allow for possible enhancements, e.g. cross-sector number portability, and MNP between analogue and digital mobile networks. Additional functionalities not documented in the present document may implement requirements which are considered outside the scope of the present document. This additional functionality may be on a network-wide basis, nation-wide basis or particular to a group of users. Such additional functionality shall not compromise conformance to the core requirements of the service.
Porting between Service Providers (i.e. service provider portability) which does not involve a change of Network Operator is outside the scope of the present document.
The relationship between Service Providers and Network Operators is outside the scope of the present document.
The relationship between a Service Provider and subscriber is outside the scope of the present document. The interface between the Mobile Station (MS) and any external applications are outside the scope of the present document. Charging principles are outside the scope of the present document except where explicitly stated in the text.
