3GPP IMS (IP Multimedia Subsystem) is the next generation network for delivering IP multimedia services. IMS is standardized by the 3rd Generation Partnership Project (3GPP). 
IMS services could be used over any type of network, such as 3GPP LTE, GPRS, Wireless LAN, CDMA2000 or fixed line.

3GPP IMS（基于IP的多媒体子系统）是下一代IP多媒体子系统网络传输规范。IMS已被3GPP组织标准化. IMS服务将被使用在任一类型的网络上，如3GP LTE ，GPRS ,WLAN, CDMA2000 等已经被定义好的通信基带

Doubango框架是3GPP IMS(多媒体子系统(移动业务))的一种实现，目前IMS已被3GPP国际组织标准化，IMS所支持的服务将能在任一种网络中实现,这些网络包括3GP LTE(4G), GPRS, WLAN, CDMA2000等已经公用的通信网络协议

doubango is the world's most advanced open source 3GPP IMS/RCS framework for both embedded and desktop systems.
The framework is written in ANSI-C to ease portability and has been carefully designed to efficiently work on embedded systems with limited memory and low computing power and to be extremely portable.

Doubango 是当前世界上最好的一个基于3GPP IMS/RCS 并能用于嵌入式和桌面系统的开源框架。该框架使用ANSCI-C编写，具有很好的可移植性。并且已经被设计成 非常轻便且能有效的工作在低内存和低处理能力的嵌入式系统上
