A METHOD FOR DETERMINING INBOUND ROAMING TRAFFIC MARKET SHARE ON CELLULAR NETWORKS

摘要

A method of determining inbound roaming market share of a host network is disclosed. The network subscribers are identified by their subscriber identity (IMSI). Each IMSI is categorized based on its roaming status. The roaming categories are as follows: successfully roaming, roaming but steered to another network, not roaming due to errors related to steering, not roaming due to errors not related to steering, roaming below a threshold, roaming below a threshold duration, and roaming on rival networks. SRI-for-SM results of SMS activity are used to determine the count of IMSIs roaming on rival networks. Market share is determined by calculating a quotient of the count of IMSI's categorized as successfully roaming on the host network and the difference between the total count of the IMSIs and the count of IMSIs categorized as not roaming due to errors not related to steering.
