104 results about "Telephone number mapping" patented technology

Telephone number mapping is a system of unifying the international telephone number system of the public switched telephone network with the Internet addressing and identification name spaces. Internationally, telephone numbers are systematically organized by the E.164 standard, while the Internet uses the Domain Name System (DNS) for linking domain names to IP addresses and other resource information. Telephone number mapping systems provide facilities to determine applicable Internet communications servers responsible for servicing a given telephone number using DNS queries.

Method for realizing routing for next-generation network

In the invention, phone number mapping (ENUM) mechanism is inducted to complete route function. The hierarchical route technique makes network convert from plate structure to layered structure. Based on called number, calling entity obtains domain name and corresponding IP address from server of phone number mapping (ENUM server) and domain name system (DNS) so as to initiate a message of call setup to the IP address directly. The said entity includes soft switch (SoftSwitch), session initiate protocol user agent (SIP UA) or session initiate protocol proxy server (SIP Proxy) etc. The invention overcomes disadvantages of current route technique of static configuration, provides a method for realizing route selection in NGN effectively so as to make network maintenance and management convenient and easier to expand as well as make interconnection between networks easier.

Method and system for measuring market-share for an entire telecommunication market

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.

Method and apparatus for synchronizing ported number data

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. If the LRN to 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 in. The method further comprises receiving a notification message for the LRN at a number portability data manager, wherein: if the notification message indicates that a DN has ported in, then the number portability data manager sends a request to an ENUM (telephone number mapping) server to turn the entry for that DN on; and if the notification message indicates that a DN has ported out, then the number portability data manager sends requests to the ENUM server and to a subscriber database to turn the entry for that DN off.
