A telecommunications system and method is disclosed for collecting mobility information regarding mobile subscribers and providing this mobility information to telemarketing companies to generate extra revenue for cellular network operators. A telemarketing application can define a target area, which includes a cell or a number of cells that are of interest for the telemarketing application, and include this defined target area in a mobility request to an Operation and Support System (OSS) within the cellular network. The OSS instructs Mobile Switching Centers (MSCs) within the target area to log the movement of each MS located in the target area and store this mobility information in a Home Location Register (HLR) or Visitor Location Register (VLR). Once all the mobility information has been collected by the MSC's, the mobility information is passed onto the OSS, which can utilize filter parameters specified by the telemarketing application in order to generate tailored mobility information.
