How does a GSM phone display location name ?
Posted on 2009-04-05
The Nokia phones in India which work on GSM display the name of the locality in which the user is currently. For eg Andheri, Juhu etc.
How does the phone know about the locality, I know it continually receives the cell Id of the base station it is camped too, however I doubt that the phone has some cell Id to location look up table. It seems to me that the base station itself is transmitting that information. Let me know if the above is correct, if it is the please can you answer the following questions
a) This transmission of the area name by the base station a standard's thing or something specific to India?
b) Will the platform expose a API for any application developer to query the location name?
c) Other phones on the same network (Blackberry) does not display this information. Is there anything prohibiting them from doing so?
Looking forward t oyour response.
