A new algorithm for mobile call termination

The aim of the paper is to propose a new algorithm for mobile call termination for roaming mode that reduces the call setup time for a call from a fixed wire line to a Mobile Station that is present in the same network as that of fixed line but is in roaming mode. Hence forth, fixed wire line is referred as fixed line. The method adopted includes introduction of new node into the GSM network, namely THLR in every segment of the network where HLR is present. The paper will introduce existing algorithm in GSM along with implementation diagram and location update procedure for mobile call termination in roaming mode. Along with new algorithm, also included are implementation diagram and location update procedure. The result of the paper includes modified architecture of GSM for mobile call termination in the form of implementation diagram and location update procedure for the proposed algorithm. The paper also indicates the advantages and disadvantages of proposed algorithm over the existing algorithm. This is followed by conclusions.
