With the rapid growth of mobile services, messaging services such as SMS, MMS, USSD and mobile instant messaging are widely used. Various messaging services are provided by different vendors, so the maintenance cost of different platforms had been greatly increased.
At present, many problems need to be solved, including:
1) Each system is independently constructed, so the hardware and network resources can't be shared.
2) Each message system has an independent maintenance system, which requires a great amount of maintenance manpower.
3) Smooth migration of NFV can't be supported.
To solve the above disadvantages, ZTE has proposed Converged Message Architecture (CMA), which can simplify the system framework, retain the characteristics of existing message services, and support the NFV architecture.
