Abstract
The present invention relates to a method for providing a unique temporary international identification of a mobile station during establishment and re-establishment of a logical link between a mobile station and the associated serving GPRS (General Packet Radio Service) support node (SGSN). The unique temporary international identification allows international roaming across country borders without using the international mobile station identification (IMSI), i.e. beyond the coverage area of the home PLMN, it is according to the present invention suggested to form new identity comprising the old TLLI, the old RA, and identification of the public land mobile network (PLMN) that is the owner of the old TLLI and the country where the PLMN belong. The new identity is used as identification on the radio interface, identification within the current SGSN and for identification of the old SGSN.
