Abstract  Abstract

A lower signaling load and a shorter connection setup time in relation to the known two-stage location request is achieved with an optimal routing in that upon receiving the message (SRIL) for the location request the home register (HLRB) itself checks the feasibility of the setup of the direct connection between the gateway mobile switching center (GMSCA) of a first network (IPLMN) and the visited mobile switching center (VMSCB) of another network (VPLMN) for reasons of the charging of the call. Given a positive test result a modified message additionally containing a flag (PRN) for the request of a temporary mobile subscriber roaming number (MSRN) is sent to the visitor register (VLRB). The home register can determine the feasibility of the connection setup for charging of the call after the first receipt of a location request and can immediately (that is without waiting for a new location request by the gateway mobile switching center) call the mobile subscriber roaming number from the responsible visitor register and send it to the requesting gateway mobile switching center.
