Method, system and device for implementing automatic dual-number roaming

A system for implementing automatic dual-number roaming, which is applied to a network environment comprising a core network in an area A, a core network in an area B and an intelligent network platform, and the network environment further comprises an International Roaming (IR) platform;

• and the system comprises a subscription management unit and a trigger shielding unit, wherein
• the subscription management unit is configured to, for a Mobile Virtual Network Operator (MVNO) subscriber having a number of the area A and a number of the area B, subscribe the number of the area A to the intelligent network platform on a Home Location Register (HLR) in the area A, and subscribe the number of the area B to the intelligent network platform on an HLR in the area B, wherein the number of the area A is directed to the IR platform, and the number of the area B is directed to the HLR in the area B;
• and
• the trigger shielding unit is configured to, when the subscriber turns on a terminal in the area A, select the number of the area A, and transmit a turn-on registration message to the IR platform to trigger the IR platform to shield intelligent subscription information of the subscriber.

A device for implementing automatic dual-number roaming, as an International Roaming (IR) platform, which is applied to a network environment comprising a core network in an area A, a core network in an area B and an intelligent network platform;

• the IR platform is configured to receive a turn-on registration message from a subscriber to shield intelligent subscription information of the subscriber, wherein
• the subscriber selects the number of the area A when turning on a terminal in the area A;
• and
• for a Mobile Virtual Network Operator (MVNO) subscriber having a number of the area A and a number of the area B, the number of the area A is subscribed to an intelligent network platform on a Home Location Register (HLR) in the area A, and the number of the area B is subscribed to the intelligent network platform on an HLR in the area B;
• the number of the area A is directed to the IR platform, and the number of the area B is directed to the HLR in the area B.
