Location dependent addressing using GSM-R cellular positioning

Location dependent addressing (LDA) is an effective and efficient addressing method in GSM-R (GSM for railways), which needs information on the location of the mobile station in order to forward the call to the correct called party. It is worth developing the method to introduce GSM-R positioning techniques into the solution of LDA. The paper analyzes the possibility of using GSM-R positioning in LDA. The characteristic of GSM-R compatible with cellular positioning is given. A location system model as well as positioning techniques suitable for a GSM-R system are presented.
