Products - Number Portability Solution

Local number portability (LNP) for fixed lines, and full mobile number portability (FMNP) for mobile phone lines, refers to the ability to transfer either an existing fixed-line or mobile telephone number assigned by a local exchange carrier (LEC) and reassign it to another carrier. In most cases, there are limitations to transferability with regards to geography, service area coverage and technology. In the United States and Canada, mobile number portability is referred to simply as WNP or WLNP. In Japan and Pakistan it is referred to as mobile number portability, (MNP). Wireless Number Portability is available in some parts of Africa, Asia, Australia, and most European countries including Britain; however, this relates to transferability between mobile phone lines only. Iceland, Canada, and the United States are the only three countries in the world that offer full number portability transfers between both fixed lines and mobile phone lines because mobile and fixed line numbers are mixed in the same area codes, and billing wise are identical for the calling party, the mobile user usually pays for incoming calls; in other countries all mobile numbers are placed in higher priced mobile-dedicated area codes and the originator of the call to the mobile phone pays for the call. Hong Kong also fulfills the criteria listed above (no area code in Hong Kong, call billings are identical no matter for calling to fixed or mobile, and mobile user pays for incoming calls). Although Hong Kong government approved for fixed-mobile number portability, this service is still not available. Some cellular telephone companies will charge for this conversion as a regulatory cost recovery fee. GRV's Local Number Portability (G-LNP) Database service lets you directly access an LNP Database to perform your own LNP routing queries, rather than pay higher costs to Local Exchange Carriers (LECs) to route the calls for you. The number-portability service comprises the following solutions:

Location (geographic) number portability

allows the end users to keep their number when they move to another geographic location.

Service portability

allows the end users to keep their telephone numbers when they change the type of telecommunications service (POTS into ISDN, ISDN into POTS, etc).

Service Provider portability

allows the end users to change their service provider without changing their existing telephone (directory) number. All the information about the ported numbers is saved in the national Number-Portability Database (NPDB). G-LNP sends a request (all-call-query) for a ported number in the database, which informs the switch about the new location in the case of portability.

Attention! your switch has to provide the functionality all-call-query!
