Directing a subscriber toward a destination within an SDMA mobile radio network
First Claim
1. A process (100) for directing a subscriber toward a destination within an SDMA mobile-radio network, comprising the steps of:
- (110);
transmitting from a mobile radio terminal (MS) of the subscriber to a base station (BTS) of the SDMA mobile-radio network a message specifying the destination (DES);
(120);
determining the subscriber'"'"'s current location (LOC) by evaluating directional and/or distance information (α
, R) assigned to an SDMA radio link between the mobile radio terminal (MS) and at least said base station (BTS) of the SDMA mobile-radio system;
(130);
retrieving from a data base (DB) information data (INFO) defining a route from the subscriber'"'"'s current location (LOC) to the destination (DES); and
(140);
transmitting the information data (INFO) to the subscriber'"'"'s mobile radio terminal (MS).

Abstract
A process for directing a subscriber toward a destination within an SDMA mobile radio network, and a processor-controlled facility (BSC) which operates accordingly are proposed. This facility contains a communications interface unit (IF1) for receiving a message that specifies a destination (DES) desired by a subscriber, and a microprocessor which determines the current location (LOC) of the subscriber by evaluating directional and distance information (α, R). The processor-controlled facility (MSC) furthermore contains communications interface unit (IF2) whereby it retrieves information (INFO) from a data base (DB), which defines a route from the location (LOC) to the destination (DES). This information is transmitted in summary form to the subscriber'"'"'s mobile radio terminal (MS).

6. A processor-controlled facility (MSC) for directing a subscriber toward a destination within an SDMA mobile-radio network, comprising a computer means (μ
- P) which is connected to at least one base station (BTS) of the mobile-radio network and which determines the subscriber'"'"'s current location (LOC) by evaluating directional and/or distance information (α
, R) assigned to an SDMA radio link between the at least one base station (BTS) and a mobile radio terminal (MS) of the subscriber, characterized by a first communications interface unit (IF1) which provides the connection between the computer means (μ
P) and the at least one base station (BTS) and receives a message from the subscriber specifying a destination (DES), and by a second communications interface unit (IF2) which provides the connection between the computer means (μ
P) and a data base (DB) and retrieves information data (INFO) from the data base defining a route from the subscriber'"'"'s current location (LOC) to the destination (DES), said information data (INFO) being transmitted from the first communications interface unit (IF1) to the mobile radio terminal (MS) of the subscriber. - View Dependent Claims (7, 8, 9)
