A method for use in a wireless network to obtain requested location information regarding a wireless station from any of various location sources and provide the requested location information to a wireless location application, the wireless network being associated with at least a first source of location information and a second source of location information for providing information regarding locations of wireless stations in the network, the method comprising the steps of:

  • first receiving a location request regarding said wireless station from said wireless location application, said location request seeking said requested location information;

    second receiving a first location input based on first location information from said first source, and a second location input based on second location information provided by said second source, wherein said first location information and said second location information are provided in different formats relating to identification of wireless station locations;

    wherein said first location finding equipment employs a first location finding technology and said second location finding equipment employs a second location finding technology different than said first location finding technology, and said step of second receiving comprises standardizing information obtained from said first location finding equipment and second location finding equipment to provide said respective first and second location inputs, wherein said first and second location inputs include location information in a standardized format;

    storing data in memory relating to said first location input and said second location input;

    obtaining said requested location information by selectively retrieving data from said memory based on said location request; and

    outputting said requested location information to said wireless location application, wherein said wireless location application is supported by said first location finding equipment and said second location finding equipment, wherein said step of first receiving comprises providing an interface defining a format for receiving a location request from said wireless location application, said format allowing said wireless location application to specify at least one parameter regarding said request location information, and receiving said location request in accordance with the defined format.
