摘要：With the rapid increase in international roaming and highly growing number of cellular subscribers it is important to locate the subscriber both efficiently and accurately not only to reduce the cost but also to decrease the load on MSC and decrease the paging delay. The procedure used by the service provider for both collecting and analyzing the information regarding the subscribers' location is called location management. Location management comprises of location update and paging schemes. This paper tried to highlight the different location management techniques and paging schemes that are used in CDMA network. This paper also compares their features, merits and demerits. Finally the paper discusses various techniques that are used in order to optimize the location update schemes by categorizing them into two broad groups' i.e. static location update and dynamic location update. Each group enlists different techniques that are used to decide the update frequency of MS (Mobile System). This study has tried to summarize their underlying concepts and various pros and cons.
