SS7 Registration

Does SS7 handle new Telephone Number Registrations into the Database?

[admin]

Numbers in Mobile Networks do register (update their location) to the network and their information is stored in the HLR/VLR ?

please elaborate your question?

My query is regarding addition of new numbers to Database:

Recently, I wen't through typical SS7 architecture and found that there are 3 main components involved in it:

1. Service Switching Point (SSP)
2. Service Control Point (SCP)
3. Signal Transfer Point (STP)

Here, SCP serves as an interface to Telephone Company Databases. So, does it mean that SS7 also handle adding new numbers to Database when ever a new number is assigned to any particular Customer or an Enterprise?

NO, the ss7 network can not handle registratios by itself

ehen new numbers are added to a customer in the PSTN network wireless or wireline those are activated through provisioning datafill on their own switch

SCP (service control point) is accessed by the swicthes to resolve inteligent services as 800 number resolutions and it has databases for that resolution
also serve as LNP local number portability service

the update of the LNP database usually is replicated from another Database national when new ranges of numbers are assigned to differents operators..

SCP itself is a sort of Telephone database that also provide services. Addition of new numbers is normally not done via SS7, infact a subscriber/number can only communicate and avail services of SCP via SS7. Number is created on SCP via its internal application interfaces and then subscriber can activate and use services via SS7.

There are few scenarios where number creation can be done via SS7 e.g. a small SCP providing voice mail service. A subscriber uses SS7 to contact SCP and on SS7 request, SCP adds the number to its database and creates an account for it.

But in particular SSP-STP-SCP scenario, creation is not done via SS7

I replied to your query on some other forum. Pasting that again:

SCP itself is a database for numbers and those numbers can access SCP services via SS7. In normal SSP-STP-SCP scenario, SS7 is not used to add numbers to the database but internal interfaces of SCP are used to create a number prior to assigning that number to some customer.

But in few cases SS7 can be used e.g.
a voice mail server is kinda small SCP. Whenever subscriber makes a call to voice mail, voice mail server creates an account for it in its database if the account do not exist already.

vmarines and JDK,

Thanks a lot for providing me with this information.
