Abstract

In one arrangement, a method of operating a mobile user terminal in a communications system includes monitoring received broadcast signals and deriving first identification data of fixed wireless nodes from the received broadcast signals. The method includes using data derived from a stored database in combination with the derived first identification data in order to provide a service to a user of a mobile user terminal. The method includes deriving update data from at least the derived first identification data and transmitting the derived update data to a database administration node in order to allow the stored database of fixed wireless nodes to be updated.

(a) monitoring received broadcast signals;

(b) deriving first identification data of fixed wireless nodes from said received broadcast signals;

(c) using data derived from said stored database in combination with said derived first identification data in order to provide a service to a user of said mobile user terminal;

(d) deriving update data from at least said derived first identification data; and

(e) transmitting said derived update data to a database administration node in order to allow said stored database of fixed wireless nodes to be updated.

2. A method according to claim 1, said mobile user terminal having a replica database derived from said stored database of fixed wireless nodes, wherein said update data is derived in step (d) by processing in relation to said replica database.

3. A method according to claim 2, wherein step (d) comprises the steps of:

comparing derived first identification data with first identification data of said replica database; and

determining from said comparison new fixed wireless nodes, if any, for which derived first identification data does not match an entry in said replica database.

4. A method according to claim 2, wherein step (d) comprises the steps of:

comparing derived first identification data with first identification data of said replica database; and

determining from said comparison missing fixed wireless nodes, if any, for which an entry in said replica database does not match derived first identification data.

5. A method according to claim 1, wherein said stored database includes, in addition to said first identification data, second data associated with said fixed wireless nodes.

6. A method according to claim 5, wherein said second data includes geographic location data.

7. A method according to claim 6, wherein said update data includes geographic location data.

8. A method according to claim 7, said mobile user terminal further having a satellite positioning system, said geographic location data in said update data being derived from an output signal of said geographic positioning system.

9. A method according to claim 7, said geographic location data in said update data being derived from said geographic location data of said second data associated with said fixed wireless nodes of said stored database.

10. A method according to claim 9, wherein said mobile user terminal does not include a satellite positioning system.

11. A method according to claim 1, said mobile user terminal having means to derive data representing signal strength of received broadcast signals.

12. A method according to claim 11, wherein said update data includes said signal strength data.

13. A method according to claim 1, said method comprising the further step of:

(f) receiving update data derived from said stored database of fixed wireless nodes in response to transmitting said derived update data.

14. A method according to claim 1, wherein said service provided in step (c) is a service based on a current location of said mobile user terminal, said current location being determined based on said derived first identification data.

15. A method of updating a stored database of fixed wireless nodes accessed via a database administration node in a communications system, said stored database identifying fixed wireless nodes which are geographically dispersed and which broadcast a signal containing at least first identification data, said fixed wireless node being identified in said database by first identification data, said method comprising the steps of:

receiving update data at said stored database from a service application of at least one mobile user terminal, said service application using data derived from said stored database in combination with first identification data which is derived from broadcast signals received at said at least one mobile user terminal in order to provide a service to a user of said mobile user terminal, said update data being derived from said derived first identification data; and

updating said fixed wireless nodes database with said received update data.

16. A method according to claim 15, said received update data comprising first identification data, said method comprising the further steps of:

comparing first identification data of said received update data with first identification data of said stored database; and

determining from said comparison new fixed wireless nodes, if any, for which first identification data of said received update data does not match an entry in said stored database.

17. A method according to claim 15, said received update data comprising first identification data, said method comprising the further steps of:

comparing first identification data of said received update data with first identification data of said stored database; and

determining from said comparison missing fixed wireless nodes, if any, for which an entry in said stored database does not match first identification data of said received update data.

18. A method according to claim 16, wherein said stored database includes, in addition to said first identification data, second data associated with said fixed wireless nodes.
