Abstract

The invention relates to a subscriber service for establishing a connection between an A-subscriber (A1) and a B-subscriber (CXN61) in a telecommunications network (601). The A-subscriber wishes to be connected to any B-subscriber located in a given geographical area (GL64). The A-subscriber (A1) enters a subscriber service code which is received in a control unit (CPUk) in a switching station (PBXk). The subscriber service code includes a connection path (PBX1-REX2-BS64) to the area (GL64). The control unit (CPUk) localizes B-subscribers available in the are (GL64) and stores these subscribers in a preliminary list in a memory (605). Also stored in the list are B-subscribers that are permanently associated with the area (GL64). The control unit then set one or more B-subscribers from the preliminary list and then establishes the connection.

Dependent claims

A method of performing a subscriber service in a telecommunications network (601, 101) which includes at least one switching station (PBX1-PBX3, PBXk;

GMSC), at least one radio exchange (REX1-REX6;
MSC1) and at least one base station (BS61-BS64;
BS11-BS12) for setting-up a connection between a calling A-subscriber (A1) and at least one called B-subscriber (CXNT1, MS1-MS5), said method comprising:
allocating subscriber service codes to separate geographical areas (GL11-GL12, GL41-GL44, GL64), each including at least the area covered by a base station;
associating the B-subscribers (MS1-MS3, CXN44-CXN46, CXN61) with a respective geographical area (GL11, GL44, GL64);
entering the subscriber service code, said code being entered by the A-subscriber and indicating the geographical area (GL64;
GL11-GL12) in which the connection with the B-subscribers shall be established;
localizing the B-subscribers that are associated with the geographical area (GL64;
GL11-GL12) given by the A-subscriber;
selecting at least one of the localized B-subscribers;
and
establishing the connection from the A-subscriber to the selected B-subscribers, said subscribers constituting the called B-subscribers.

9 more elements

A telecommunications network (601, 101) in which there is provided a subscriber service for establishing a connection between a calling A-subscriber (A1) and at least one called B-subscriber (CXN61, MS1-MS5), wherein the telecommunication network (601, 101) includes at least one switching station (PBX1-PBX3, PBXk;

GMSC), at least one radio exchange (REX1-REX6;
MSC1) and at least one base station (BS61-BS64);
BS11-BS12), wherein
the calling A-subscriber (A1) has means whereby a subscriber service code can be entered, said code entered by said A-subscriber indicating a geographical area (GL64) to which the connection with the B-subscriber shall be established;
Wherein at least one of the switching stations (PBXk) has a control unit (CPUk) which includes subscriber service storage means and means for receiving and decoding the subscriber service code;
wherein means (606, REX2) are provided for storing the B-subscribers that are associated with respective geographical areas;
wherein the control unit (CPUk) has means for localizing the B-subscribers that are associated with the geographical area given by the A-subscriber in the subscriber service code and means for storing the localized B-subscribers in a memory (605);
wherein the control means (CPUk) has means for selecting at least one of the B-subscribers in the memory (605);
and
wherein the control unit (CPUk) has means for ordering the connection to be established to the selected B-subscribers.
