BSS Evolution

BSS Evolution

Business Support Systems (BSS) are critical in telecom operations, managing the entire customer lifecycle and driving revenue. Their evolution is fragmented due to legacy systems, diverse ownership, and strategic priorities. Global telco spending on BSS is projected to exceed $37 billion annually by 2029, growing at a 2.8% CAGR.

This research note traces the divergent evolution paths of telco BSS by analyzing transformation patterns across six critical functional domains—billing, charging, mediation, partner management, B2C systems, and B2B systems.
