Personal Communication Systems (PCSs) must have an efficient way to locate mobile users. The location management fulfills this task through location registration and paging. To reduce the signaling traffic, many schemes such as local anchoring, pointer forwarding and two-level pointer forwarding schemes have been proposed in the past. In this paper, we present a novel location management scheme which intends to mitigate the signaling traffic as well as reduces the connection setup delay in the PCS networks. In this strategy, one VLR is selected as the Mobility Agents (MA) for that user at a time, which forms another level of management to make some registration signaling traffic localized. The analytical results show that this strategy can significantly reduce the network signaling traffic for users without increasing much of the call setup delay. Also in our new scheme, the signaling burden is evenly distributed and the selection of MA is dynamic for every user.
