Abstract

A method for registering traffic data from mobile stations in a mobile telecommunication system. The mobile telecommunication system includes mobile switching centers and connected with these, base station controllers, so-called primary- and secondary base station controllers. Base stations are connected to the base station controllers, each base station covering a cell and each base station controller thereby covering a cell area containing several cells. Traffic data from a selected mobile is stored in the primary base station controller of the mobile. A trace invocation message is sent from the primary base station controller to the secondary base station controller, via the mobile switching center, when the mobile moves to a cell handled by the secondary base station controller. Registration of traffic data is thereafter effected in the secondary base station controller.

Claims

1. A method for registering traffic data from mobile stations in a mobile telecommunication system which includes at least one mobile switching center, a visitor location register connected to the switching center, at least two base station controllers connected to the switching center, each of said base station controllers being connected to at least one base station, wherein the radio covering area of respective base stations is called a cell and a group of cells belonging to a switching center is called a service area, and wherein, subsequent to a mobile station entering said service area, the mobile station is registered in the visitor location register, said method comprising the steps of:

selecting at least one of the mobile stations from said visitor location register;

determining, by specifying a trace invocation message, the type of traffic data to be registered, which data arises during the registration;

ordering the switching center to send the trace invocation message to the base station controller which handles the cell group in which the selected mobile station is located;

fulfilling a start condition, wherein a call is connected to the selected mobile station;

sending the trace invocation message from the switching center to a primary base station controller which handles the cell in which the selected mobile station is located;

storing in a database in the primary base station controller traffic data incoming from the selected mobile station;

sending the earlier specified trace invocation message, when the selected mobile station crosses a boundary between two cells handled by different base stations controllers, from the switching center to a secondary base station controller which handles the cell in which the selected mobile station is now located so as to continue registering the traffic data as originally specified by the trace invocation message; and

storing the a database in the secondary case station controller traffic data incoming from the selected mobile station.

3. A method according to claim 1, wherein a predetermined number of binary digits which discloses which traffic data from the mobile station shall be stored in the database are included in the trace invocation message.

4. A method according to claim 3, wherein the commands are sent from an external unit connected to the switching centers and the base station controllers.

5. A method according to claim 4, wherein the commands are generated when an established criterion has been fulfilled in a program, said program being located in either the switching center, the base station controller, or the external unit.

6. A method according to claim 5, wherein traffic data stored in the database is collected and read-out by the external unit.

2. A method for registering traffic data from mobile stations in a mobile telecommunication system which includes at least one mobile switching center, at least two base station controllers connected to the switching center, each of said base station controllers being connected to at least one base station, where the radio covering area of respective base stations is called a cell, said method comprising the steps of:

determining, by specifying a trace invocation message, the type of traffic data to be registered, which data arises during the registration;

ordering, by giving an order command to a primary station controller in which a selected mobile station is located, said base station controller to create the trace invocation message;

fulfilling start conditions at the selected mobile station;

storing traffic data incoming from the mobile station in a database in the primary base station controller;

sending the trace invocation message from the primary base station controller to the switching center;

sending the earlier specified trace invocation message, when the mobile station crosses the boundary between said two cells, from the switching center to a secondary base station controller which handles the cell in which the selected mobile station is now located so as to continue registering the traffic data as originally specified by the trace invocation message; and

storing traffic data from the selected mobile station in a database in the secondary base station controller.

7. A method according to claim 2, wherein a predetermined number of binary digits which discloses which traffic data from the mobile station shall be stored in the database are included in the trace invocation message.

8. A method according to claim 7, wherein the commands are sent from an external unit connected to the switching centers and the base station controllers.

9. A method according to claim 8, wherein the commands are generated when an established criterion has been fulfilled in a program, said program being located in either the switching center, the base station controller, or the external unit.

10. A method according to claim 9, wherein traffic data stored in the database is collected and read-out by the external unit.
