Il Huawei BSC 6900 (Base Station Controller) is a next-generation mobile network control platform designed to manage and optimize the operation of GSM, EDGE, and UMTS (3G) radio access networks. It acts as an intermediary between the mobile base transceiver stations (BTS) and the mobile switching center (MSC), managing radio resources, handovers, and the mobility of subscribers. The BSC 6900 was engineered for high capacity, scalability, and energy efficiency, making it an integral part of Huawei’s broader unified RAN (Radio Access Network) strategy.
One of the key innovations of the BSC 6900 is its unified architecture, which allows it to support both GSM and UMTS on a single platform. This convergence simplifies deployment, reduces equipment footprint, and lowers total cost of ownership for mobile operators. It is capable of handling multiple control and user plane protocols, supporting traditional circuit-switched traffic as well as data-centric services through EDGE or HSPA technologies.
The BSC 6900 has been widely deployed across global networks and remains a critical piece of infrastructure in hybrid 2G/3G environments. Though many operators have begun transitioning to 4G and 5G technologies, the BSC 6900 continues to provide stable, reliable performance for legacy voice and data services, particularly in developing markets or areas with slow migration from GSM.
Carritech supports mobile network operators using the Huawei BSC 6900 by sourcing original hardware components, controller cards, and expansion modules through our global supplier network. All hardware is tested and verified to meet operational standards, helping customers maintain or expand their legacy mobile network infrastructure with confidence.

| Time Period | Brand / Company | Role / Notes |
|---|---|---|
| 2008 – 2020 | Huawei Technologies Co., Ltd. | Designed, manufactured, and promoted the BSC 6900 globally as a key platform in its GSM/UMTS network portfolio. Deployed widely in emerging and developed markets. |
| 2020 – Present | Huawei (limited availability) | As networks migrate to 4G and 5G, the BSC 6900 is no longer actively promoted, but remains supported in existing deployments through software maintenance and parts replacement. |
| Present (Secondary Market) | Independent Resellers & Support Specialists (e.g., Carritech) | Carritech sources and supplies Huawei BSC 6900 components—including chassis, controller cards, and expansion modules—providing lifecycle extension and operational support for legacy mobile networks. |
