The intelligent network signaling and switching costs of an alternate location strategy using memory

In future high density microcellular personal communications systems (PCS), it is expected that most of the signaling traffic will come from registrations. An alternate location strategy has been proposed to reduce the signaling traffic on the radio link by increasing the responsibilities placed upon the fixed network. A fixed network performance comparison to the classic location strategy being implemented in evolving digital cellular and cordless standards is presented. The key measures are SS7 traffic and switching complexity. An example based on the Groupe Speciale Mobile (GSM) system illustrates the results
