This work investigates the problem of location methods putting load on GSM network. The work carried out covers analysis of various location methods, identification of network nodes and datapaths that are involved in getting location data from GSM network. It is shown that methods can generally be divided into two groups: those that use special devices to locate and then transfer results via GSM network and those that use GSM network for positioning. The impact of first group on GSM network load is limited to the time of data transfer time that depends on the coding scheme used, data transfer channels allocated and size of location data. The impact of second group depends on algorithm used. Analysis and experiments carried out using custom GSM network emulator show that standard “Provide Subscriber Info” based algorithm requires mandatory update of location information within GSM network using either SMS or preempted call setup that both require radio resources. Usage of “Customer Trace” algorithm for self-location applications is proposed to save radio resources. Additional benefits of this algorithm include usage of timing advance and signal strength information from “Customer Trace” data to increase the accuracy of location within current GSM network infrastructure.
