A low-cost, two-step location update/paging scheme in a macrocell/microcell network is proposed and investigated. To reduce operating cost, the location update is operated only in the macrocell tier. A callee will be paged in the macrocell tier first. If the paging delay in the macrocell tier is too high due to large queuing delay, the callee will then be paged in the microcell tier. Original searching method is used in the microcell tier paging. The operation for the scheme is simple, sincedoi:10.1145/940929.940932 fatcat:gy3u6ysanbdbbeftgo4e3gugbi
