35、raphic and Non-Geographic number portability. The study will focus on a review of IN Capability Sets 1,2 and identify any desirable enhancements to support number portability under IN CS3. The report will recognize that an IN solution can provide high functionality with fairly high throughput or tra
36、ffic handling capability but Number portability may oniy require relatively low functionality. It should also be noted that IN Capabilities might exist in Originating, Donor, Transit or Recipient Networks. The report takes account of the requirement to minimize additional costs and avoid extended ca

Siling aspects are outside the scope of the present document. 1.1 Purpose The purpose of the present document is to provide scope guidance toward the following stages of the Number Portability Standards process. 2 References The following documents contain provisions which, through

45、er being ported. 3.1.3 Geographic Number (GN) A Geographic Number (GN) is a Directory Number from that part of the national numbering scheme that is used to identify fixed line terminations. Prior to Number portability these numbers are geogmphical in that sense that they convey the location of the
46、customer. 3.1.4 Geographic Number Portability (GNP) See Service Provider Portability for Geographic Numbers. 3.1.5 Network Operator A Network Operator is an entity that operates public telecommunications network in order to mute calls. 3.1.6 Non Geographic Number (NGN) Non-geographic Number (NGN) is
47、 a Directory number that is not a Geographic Number. A Non-geographic Number does not imply the Geographic location of the customer. 3.1.7 Non Geographic Number Portability (NGNP) See Service Provider Portability for Non Geographic Numbers. 3.1.8 Number Translation Function Number Translation Functi

This is achieved by reference to a database to obtain, for example, a users profile, or time of day requirements. Intelligence can be provided by an Intelligent Network which has specified standard Interfaces between Service Control Functions, Switching Functions, Specialized Resource Functions
