| 20110170538 | Method and System for Communications Roaming - A method and system for communications roaming discloses that end subscribers apply for numbers provided by roaming networks, connect their numbers in local networks to roaming network ones and then store them in the database in Global Roaming Interface Agent (GRIA). When a called number is dialed, the calling communications network first determines if the calling number or the called number belongs to a number in local network. If no, the calling network sends Global Roaming Interface Agent a request to search and check if the number in roaming network is stored under the calling number or the called number; if yes, the corresponding calling number or called number in roaming network will be used as the number for communication. Taking the technical solution from this invention, a flexible and low-cost global roaming communications system can be achieved by binding subscribers' multiple numbers to establish a uniform end-subscriber communications interface. | 07-14-2011 |
