摘要:

为了实现下一代网络在控制层的融合,需要具有支持异构网络环境媒体控制功能的呼叫模型。在对媒体控制模型概念进行定义的基础上,针对下一代网络的特征,分析了现有各种媒体控制模型的局限性。提出了一种媒体控制逻辑状态抽象和具体控制协议适配相结合的媒体控制模型,通过实际应用证明了该模型具有异构网络环境中的统一媒体控制能力,从而实现了下一代网络在媒体控制层面的融合,同时该模型具有良好的灵活性和可扩展性。

关键词: 下一代网络, 媒体控制, 呼叫控制, 网络融合

Abstract:

The convergence of the control layer of the Next Generation Network (NGN) requires the call control model supporting the media control in heterogeneous network environment. Based on the definition of media control models, the limitation of the media control models in existence was analyzed aiming at the characteristics of NGN. A novel media control model based on the abstraction of media control states with specific control protocols adaptation was proposed. The application proved that the model in supporting media control in heterogeneous network environment of NGN had the capability to converge the control layer of NGN, as well as the flexibility and extensibility of the model.

Key words: next generation network, media control, call control, network convergence
