(57) Abstract Telecommunication network (200) are times when the conversion server (202) where the mapping table which NGPN and HLR correspondence is attached (NGPN-to-HLR) is placed is included. As for the conversion server (TS) there are times when it consists of several manners. As for this server or multiple TS there are times when it is placed on network. When the group of conversion servers are used, as for the VLR (128) or other network entity which receives NGPN it judges those which mapping are done have been put that NGPN on which conversion server. As for one manner which does this, when a certain subscriber comes out outside of his own foam/home area, NGPN of that subscriber is to be presented service provider outside area of the to TS. Outside TS of this area in other all TS inside network simultaneously, or broadcasts inquiry with several stages. Already one manner VLR which receives NGPN is to run hash function concerning that NGPN. With this hash function, it is which conversion server, it is distinguished. After that, as for VLR inquiring to that conversion server, it can obtain the mapping to HLR from NGPN. When hash function is used, open-ended hash function alteration the VLR operating system, it is used in order to accept the addition of TS where also the te is new
