A New Algorithm for Call Setup From a Fixed Wireline to a Roaming Mobile Station in an Adjacent Network
The objective of the paper is to propose a new algorithm for call setup from a fixed wireline to a roaming Mobile Station in an adjacent network. Hence, forth, fixed wireline is referred to as fixed line. The method adopted includes introduction of a new node into the GSM network, namely, AHLR that will be present in the network of every operator spanning the area that is treated as native for the AHLR. The paper will introduce the existing algorithm in GSM along with implementation diagram and location update procedure for call setup from a fixed line to a roaming Mobile Station in an adjacent network.
