Method of establishing a connection between a calling subscriber of a telecommunications network and a called mobile target subscriber of a mobile radio network

摘要

A target subscriber (SB) of the target group defined by a group call number who is best suited with respect to the calling subscriber (SA, SA') of the tele-communications network (PSTN, PLMN') is selected in order to establish a connection with this mobile target sub- scriber (SB). Before the selection of the mobile target subscriber (SB), information on the locations of the mobile subscribers of the target group defined by the dialled group call number and information on the location of the calling subscriber (SA, SA') of the tele-communications network (PSTN, PLMN') is determined and evaluated by the items of equipment of the mobile radio network (PLMN). If there is a network architecture sustaining the structure of an intelligent network, a service control point (SCP) in the intelligent network assumes the selection of the mobile target subscriber (SB). The optimal target subscriber (SB) with respect to the calling subscriber (SA, SA') is, for example, the closest mobile subscriber from the called target group.
