A method for collecting data to measure market-share for a defined telecommunication market. A market of interest is defined and a random panel of numbers is created. A call set-up is initiated to the created random panels by generating signaling messages wherein the signaling messages access a Calling Name Services (CNAM) database, a Local Number Portability (LNP) database, an E-911 Automated Location Information (ALI) database and a Line Information Database (LIDB) using signaling system 7 (SS7) protocol. Generated signaling messages access ENUM (Telephone Number Mapping) database and Internet Protocol (IP) Peering database using IP. The response to the generated signaling messages are used to determine assignment status, business ownership, businesses versus residential status and the technology employed for a given number in the created panel. In one embodiment, the process is repeated over a period in order to determine changes to the market-share and derivative metrics for the telecommunication market.

A method of synchronizing ported number data within a telecommunications network in which a number portability administration center has received a request from a subscriber having a directory number (DN) to port is provided. The method comprises the steps of: a Number Portability data manager sending a subscription request to the NPDB to receive future notifications about subscriber ports to / from specific Location Routing Number(s); the NPDB honoring these subscriptions when a user ports their DN. If this is the initial LRN assigned to the DN, then the NPDB derives the LRN of the code holder. If the LRN from which the subscriber ported has a subscription, then the NPDB sends a notification message to the NP data manager with which the LRN is associated indicating that the DN ported out.
