Method and apparatus for enhanced 911 location using power control in a wireless system
View Patent ↗Methods of selecting a transmitter power for a mobile telephone include receiving a telephone number and transmitting a control message associated with selection of a transmitter power if the telephone number meets a predetermined criterion. For example, if the telephone number is an emergency service number or number associated with a navigation assistance service, the control message is transmitted.
1. A method of selecting a transmitter power for a mobile telephone, comprising:
receiving a telephone number; and
a mobile telephone system transmitting a control message, in response to the received telephone number meeting a predetermined criterion, wherein the control message is associated with selection of a transmitter power for the mobile telephone.
2. The method of claim 1 , wherein the received telephone number is a dialed number from the mobile telephone.
3. The method of claim 1 , wherein the received telephone number is a MIN.
4. The method of claim 1 , wherein the received telephone number is a called number.
5. The method of claim 1 , wherein the transmitter control message is associated with an increased transmitter power.
6. The method of claim 1 , wherein the transmitter control message is associated with a decreased transmitter power.
7. The method of claim 1 , wherein the predetermined criterion is that the received telephone number is an emergency services number.
8. The method of claim 1 , wherein the predetermined criterion is that the received telephone number is 911.
9. The method of claim 1 , wherein the predetermined criterion is that the received telephone number is a navigation assistance number.
10. A method of selecting a transmitter power for a mobile telephone operating in a mobile phone system, comprising:
receiving a telephone number;
the mobile phone system selecting a transmitter power for the mobile telephone based on the received telephone number; and
transmitting a control message, in response to the telephone number meeting a predetermined criterion, wherein the control message is associated with selection of a transmitter power for the mobile telephone.
11. A method of selecting a transmitter power for a mobile telephone operating in a mobile phone system, comprising:
receiving a telephone number;
the mobile phone system selecting a transmitter power for the mobile telephone based on the received telephone number, wherein the received telephone number is a mobile identification number (MIN) from the mobile telephone, and the transmitter power is selected by querying a user profile database with the MIN to determine whether to invoke a transmitter control function.
12. The method of claim 11 , further comprising invoking the transmitter control function based on the query.
13. The method of claim 10 , wherein the received telephone number is a dialed number from the mobile telephone.
14. The method of claim 10 , wherein the received telephone number is a mobile identification number.
15. The method of claim 10 , wherein the received telephone number is a called number.
16. The method of claim 10 , wherein the transmitter control message is associated with an increased transmitter power.
17. The method of claim 10 , wherein the transmitter control message is associated with a decreased transmitter power.
18. The method of claim 10 , wherein the predetermined criterion is that the received telephone number is an emergency services number.
19. The method of claim 10 , wherein the predetermined criterion is that the received telephone number is 911.
20. The method of claim 10 , wherein the predetermined criterion is that the received telephone number is a navigation assistance number.
