1. A method for concurrently paging, in a cellular system having a plurality of users, the users being paged to determine a location of each user, the paging to one of the plurality of users originating from one of a plurality of cells, any of the users being located in any of the cells with a given unique probability corresponding to the user and the cell, the paging from the cell to one of the users occurring within one of a plurality of time slots, the time slot in which one of the users is paged in one of the cells being a characteristic of the one cell and the one user, wherein an array encompassing a totality of the characteristics time slots constitutes a search schedule, and, wherein, in one of said time slots, only one of the users is paged from one of the cells, the method comprising the steps of: minimizing a characteristic function of paging performance, said function depending on the search schedule and the probability of finding a user in a cell; determining, from the minimization of the characteristic function, the search schedule.
