Abstract

A method for positioning a wireless communication device includes storing position data relating to one or a plurality of reference areas to at least one data base. It is examined which of said reference areas is located in the vicinity of the wireless communication device, and at least position data about the reference area located in the vicinity of the wireless communication device is retrieved for the wireless communication device. In order to perform the positioning, the method further includes selecting the reference area located in the vicinity of the wireless communication device as the default position of the wireless communication device.

Claims

1. A method for delivering assistance data for positioning of a wireless communication device, the method comprising:

storing position data relating to more than one location area codes in at least one data base,

examining which of the one or more location codes has been transmitted to the wireless communication device, where only a portion of a global cell identity is transmitted to the wireless communication device,

transmitting the assistance data to the wireless communication device, wherein the assistance data includes at least position data about the location code that has been transmitted to the wireless communication device,

receiving from the wireless communication device a determined position of the wireless communication device and the location area code,

updating the position data stored in the at least one database relating to the local area code on the basis of the determined position of the wireless communication device and the location area code, and

invoicing a user of the wireless communication device for the transmitted assistance data.

2. The method according to claim 1, further comprising:

receiving a mobile country code and a mobile network code from the mobile communication network;

retrieving position data associated with a combination of the location area code, the mobile country code and the mobile network code; and

determining the position of the wireless communication device by utilizing the position data associated with the combination of the location area code, the mobile country code, and the mobile network code as the default position of the wireless communication device.

3. The method according to claim 1, further comprising receiving the position data from the wireless communication device.

4. The method according to claim 1, further comprising retrieving the position data from a data base in the mobile communication network.

5. The method according to claim 1, further comprising receiving the position data from a data base in a network outside of the mobile communication network.

6. The method according to claim 1, wherein the position data associated with the location area code includes position data of a cell of a base station serving the wireless communication device.

7. An apparatus comprising:

an interface configured for storing position data relating to more than one location area codes,

an examining element configured for examining which of the one or more location codes has been transmitted to a wireless communication device, where only a portion of a global cell identity is configured to be transmitted to the wireless communication device,

a transmitter configured for transmitting the assistance data to the wireless communication device, wherein the assistance data includes at least position data about the location code that has been transmitted to the wireless communication device,

a receiver configured for receiving from the wireless communication device a determined position of the wireless communication device and the location area code,

wherein the apparatus is configured for updating the position data stored in the at least one database relating to the local area code on the basis of the determined position of the wireless communication device and the location area code, and

configured for invoicing a user of the wireless communication device for the transmitted assistance data.

8. The apparatus according to claim 7, wherein,

the transmitter is operable to transmit a mobile country code and a mobile network code to the wireless communication device.

9. The apparatus according to claim 7, wherein the device is operable to retrieve the position data from a data base in the mobile communication network.

10. The apparatus according to claim 7, wherein the device is operable to retrieve the position data from a data base outside of the mobile communication network.

11. The apparatus according to claim 7, wherein the position data associated with the location area code includes position data of a cell of a base station of the mobile communication network.

12. A computer program product stored on a computer usable medium for positioning of a wireless communication device, the computer program product comprising machine executable steps for:

storing position data relating to more than one location area codes in at least one data base,

examining which of the one or more location codes has been transmitted to the wireless communication device, where only a portion of a global cell identity is transmitted to the wireless communication device,

transmitting the assistance data to the wireless communication device, wherein the assistance data includes at least position data about the location code that has been transmitted to the wireless communication device,

receiving from the wireless communication device a determined position of the wireless communication device and the location area code,

updating the position data stored in the at least one database relating to the local area code on the basis of the determined position of the wireless communication device and the location area code, and

invoicing a user of the wireless communication device for the transmitted assistance data.
