Abstract:
1. A method for identifying the location of a mobile device in a wireless communication network, the method comprising: if the mobile device is camped on at least one of a GSM or UMTS network: identifying Hierarchical Cell Structure (HCS) priority number of a cell currently in use by the mobile device; selecting a first positioning method to identify the location of the mobile device when the HCS priority number is greater than a first predefined number; selecting a second positioning method to identify the location of the mobile device when the HCS priority number is smaller than a second predefined number; and performing a probabilistic method to select one of the first positioning method and the second positioning method to identify the location of the mobile device when the HCS priority number is between the first predefined number and the second predefined number; if the mobile device is not camped on at least one of a GSM or UMTS network: obtaining femto cell status in the wireless communication network; selecting a third positioning method to identify the location of the mobile device when the mobile device is using a femto cell for communication and the mobile device is determined to be in an indoor environment based on association with the femto cell; and selecting a fourth positioning method to identify the location of the mobile device when the mobile device is using a cell other than the femto cell for communication and the mobile device is determined to be in an outdoor environment based on association with the cell other than the femto cell.
