Abstract

System for mobile telecommunication, comprising a first mobile network (KTm), connected to a first nonmobile network (KTv) having routing means (X). Terminals connected to the nonmobile network may set up a connection with mobile terminals having the first or a second mobile network as their home network. A mirror register (MLR), connected to the routing means in the nonmobile network, is used to record a copy of the user profile transferred by the HLR register of the home network of a roaming mobile terminal to the VLR register of the non-home network. The user profile stored in the mirror register in this manner is then used—together with the VLR—to directy drive the routing means X of the nonmobile network KTv, as a result of which the routing path is considerably shortened.

Dependent claims

System for mobile telecommunication, comprising a first network arranged for mobile telecommunication (KTm) ù the first mobile network ù, connected to a first network arranged for nonmobile telecommunication (KTv) ù the first nonmobile network ù, suitable for setting up connections between, on the one hand, terminals (TKTv) whose connections are routed by way of routing means (X) within the first nonmobile network (KTv) and, on the other hand, terminals whose connections are routed using registers (HLR, VLR) within the first mobile network or using registers (HLR, VLR) within a second network arranged for mobile telecommunication (DTm) ù the second mobile network ù, wherein, in both mobile networks, a first register (HLR) contains information relating to mobile terminals having the first or second, as the case may be, mobile network as their home network, and a second register (VLR) contains information relating to mobile terminals which, irrespective of their home network, make use of the first or second, as the case may be, mobile network,

with, if a terminal (TKTm) having the first mobile network (KTm) as its home network, wants to make use of the second mobile network (DTm), the second register (VLR) receives a user profile from the second mobile network (DTm) from the first register (HLR) of the first mobile network (KTm), comprising system data relating to the user of said terminal,
CHARACTERISED BY a mirror register (MLR), connected to the routing means (X) in the first nonmobile network (KTv), wherein, under control of control means, a copy of the user profile given off by the first register (HLR) of the first mobile network is recorded,
routing a call from the first nonmobile network (KTv) to said mobile terminal (TKTm) making use of the second mobile network (DTm) having the first mobile network (KTm) as its home network, the control means extract routing information for the routing means (X) of the first nonmobile network from the user profile stored in the mirror register of the user of said terminal (TKTm).

System for mobile telecommunication, comprising a first network arranged for mobile telecommunication (KTm) ù the first mobile network ù, connected to a first network arranged for nonmobile telecommunication (KTv) ù the first nonmobile network ù, suitable for setting up connections between, on the one hand, terminals (TKTv) whose connections are routed by way of routing means (X) within the first nonmobile network (KTv) and, on the other hand, terminals whose connections are routed using registers (HLR, VLR) within the first mobile network, or using registers (HLR, VLR) within a second network arranged for mobile telecommunication (DTm) ù the second mobile network ù, wherein, in both mobile networks, a first register (HLR) contains information relating to mobile terminals having the first or second, as the case may be, mobile network as their home network, and a second register (VLR) contains information relating to mobile terminals which, irrespective of their home network, make use of the first or second, as the case may be, mobile network,

with, if a terminal (TDTm) having the second mobile network (DTm) as its home network, wants to make use of the first mobile network (KTm), the second register (VLR) receives a user profile from the first mobile network (KTm) of the first register (HLR) of the second mobile network (DTm), comprising system data relating to the user of said terminal,
CHARACTERISED BY a mirror register (MLR), connected to the routing means (X) in the first nonmobile network (KTv), wherein, under control of control means, a copy of the user profile received from the first register (HLR) of the second mobile network is recorded,
with, for routing a call from the first nonmobile network (KTv) to said mobile terminal (TDTm), making use of the first mobile network (KTm) having the second mobile network (DTm) as its home network, the control means (X) of the first nonmobile network extract routing information from the user profile recorded in the mirror register of the user making use of said terminal (TDTm).
