Apparatus and method for communication are provided. The solution comprises obtaining as an input a signal; sampling the signal; feeding the sampled signal to a given number of parallel correlators having a given correlation length, controlling the correlation the sampled signal in each correlator with a unique time shift section of the pilot sequence of the communication system, determining the strongest correlation peaks, and determining on the basis of the correlation peaks and corresponding time shifts the strongest pilots in the signal.

Methods and apparatus are provided for determining market statistics for communication service providers. Determinations of whether or not a sampling of telephone numbers are assigned by a particular service provider are employed to determine market statistics. A message which is used to obtain a response. The response is interpreted to determine whether or not the telephone number associated with the wireless device is assigned. Alternatively, a sampling of telephone numbers are dialed over a digital line. Based upon the result of the dialing, it is determined whether or not the telephone numbers are assigned by the service provider. Telephone numbers which have been ported between service providers in networks which employ local number portability can be accounted for in the determination of market statistics. A telephone number portability database can also be employed for determining whether or not a telephone number is assigned by a service provider.
