Enhanced bearer overhead monitoring for improved position location performance for wireless mobiles
First Claim
Patent Images
1. A method of enhanced common channel monitoring in a wireless communication system comprising:
- receiving data from common channels during an idle state to obtain location information linked to infrastructure element identification;
storing said location information in a database;
accessing said database to determine location information related to non serving base stations; and
accessing said database during an active state to determine the location information related to serving base stations that is not sent during the active state.

Abstract
A mobile station monitors common channels for information that can be used to associate a location to an infrastructure element identification. The mobile station stores such information in a database. The database can be accessed at a later time to estimate the location of the mobile station based on comparing previous location/infrastructure element ID pairs to the pairs collected at the later time.

6. A method of monitoring overhead information from non-serving sectors comprising:
-
waking up a designated period of time earlier than an assigned slot to monitor a common channel transmitted by a non-server sector to obtain location information; monitoring additional common channels transmitted by other non-serving sectors as time permits before the next assigned; and applying the location information obtained during said non-serving sector monitoring for common channel re-acquisition when acquisition of the serving sector fails during slotted-mode operation. - View Dependent Claims (7, 8)

9. A wireless communication system comprising:
-
a serving base station and one or more non serving base stations which transmit common channels containing location information linked to an infrastructure element identification; and one or more mobile stations which receive data from the common channels during an idle state to obtain the location information linked to an infrastructure element identification, wherein the one or more mobile stations store the location information linked to an infrastructure element identification in a database and access the database to determine location information related to one of the one or more non serving base stations;
whereinthe one or more mobile stations accesses the database during an active state to determine location information related to the serving base station that is not sent during the active state. - View Dependent Claims (10, 11, 12, 13)

14. A mobile station for obtaining location information in a network, the network containing a serving base station and one or more non-serving base stations which transmit common channels containing location information linked to an infrastructure element identification, the mobile station comprising:
-
a database; and a mobile station processor programmed for receiving data from the common channels during an idle state to obtain the location information linked to an infrastructure element identification, and storing the location information linked to an infrastructure element identification in the database and accessing the database to determine location information related to one of the one or more non-serving base stations;
whereinthe mobile station processor is further programmed for accessing the database during an active state to determine location information related to the serving base station that is not sent during the active state. - View Dependent Claims (15, 16, 17, 18)
