- a Visiting Location Register (VLR) in a contracted roaming network, a Home Location Register (HLR) in a home network, and at least one Roaming Number Manager (RNM) connected with the HLR in the home network;
wherein the HLR in the home network is adapted to inform an RNM corresponding to the current location of a subscriber roaming in the contracted roaming network of subscriber location update upon receiving a request from the VLR in the contracted roaming network;
the RNM is adapted to allocate a local mobile phone number from a pool of local mobile phone numbers in the contracted roaming network for the phone, store mapping between the allocated local mobile phone number and the phone, and return the allocated local mobile phone number to the HLR in the home network, wherein the allocated local mobile phone number for the phone is adapted to be utilized as a calling number to make a call or as a called number to answer a call in the contracted roaming network and released when the subscriber leaves the contracted roaming network; and
the HLR in the home network is further adapted to send the local mobile phone number in the contracted roaming network to the VLR in the contracted roaming network to be inserted in the VLR.
