  • the database can be used to reduce femto searching, (i.e., conduct femto search only if there is a match in the database).
  • the UE 220 on a frequency other than FF conducts search on FF only when there is a database match.
  • the database elements include macro pilot PN offsets, which are all visible by the UE 220 on whatever carrier it is monitoring in the idle state.
  • PN offsets are accessible to the UE in the course of routine operation in idle state, and the UE does not have to do anything different until there is a database match. Then, the UE 220 starts scanning for the HNB or femto cell 210 , which is on a different frequency. Operating this way will reduce battery drainage.
  • FIG. 3 illustrates a method augmenting a user's equipment (UE) database with information measured by a femto cell.
  • the femto cell 210 will typically have a radio that receives the Macro channels, in order to facilitate various configuration objectives like synchronization, location, pilot PN planning, etc. Consequently, since the Femto 210 in addition to its forward link transmitter, also has a forward link receiver, it itself could measure its RF environment within neighboring Macro cells. Advanced antenna configurations have interference reduction. Furthermore, this measurement is likely to be quite accurate since the Femto 210 is stationary, and can average the measurements over a long period of time. The Femto 210 can spend a lot of time searching for pilots of neighboring macro cells, integrating CDMA signals from very weak pilots. The Femto 210 performs its own measurements in Step 302 .
  • Step 304 the UE 220 connects to the Femto 210 for the first time.
  • the Femto 210 downloads its measurements or parameters to the UE database in Step 306 to determine location of the femto cell.
  • Step 308 it can compare its current measurements with the Femto's own readings to estimate its proximity to the Femto 210 as shown in Step 310 .
  • FIG. 4 illustrates refinement of autonomous and customized discovery of femto cells.
  • the location of a femto cell may be described by means of primitives comprised of macro system parameters: within the area described by base station (BS) set C, in which Pilots exceed threshold E C /Io vector D, and have phase P within tolerance Q. All these parameters may be measured with little or no change of CDMA procedure (idle or active state), hence they will have minimal cost in terms of battery life and/or network use, in contrast to e.g. A-GPS geo-location.

  • MP 0 through MP 7 are PN Offsets for macro cells and fP 1 and fP 2 are phase offsets for femto cells.
  • femto PN Offsets In the long-term, there may be as many femto PN Offsets as for macro cells. This can be achieved in a couple of ways: (1) decrement PILOT_INC, thus creating an odd-numbered PN Offsets for femto cells; and (2) re-program macro macro cellular network by re-assigning odd PN offsets to even ones.
  • 2 ⁇ /128*2i result in 64 macro PN Offsets (even numbered) and 2 ⁇ /128*(2i+1) result in 64 femto PN Offsets (odd numbered PN Offsets).

  • an over-the-air protocol is required to communicate this information between the Femto 210 and the UE 220 .
  • a simple alternative to a new communication protocol would be for the UE 220 to store the RF measurements to neighboring macro cells at the time when it receives the strongest signal from the associated femto cell. Since the strongest signal is likely to correspond to the closest location, this minimizes the error in the UE's database entry. This entry may be re-written every time the UE samples a stronger signal from the Femto.
