摘　　要：移动网与固定网存在大量共同的技术,因此,在讨论移动网的核心网和业务网时,可以与固网结合起来讨论。在全IP移动网的核心网方面,文章认为:由于采用了不面向连接的工作方式,简化了信令,克服了节点设备复杂化以及与传送网技术的发展相匹配,IP网将是全IP移动网的核心网。在全IP移动网的业务网方面,文章认为:因为电路交换网与分组交换网网络特性的差别,全IP移动网的业务网设计应当有别于目前简单的映射电路交换网的业务网设计,应该符合分组交换网网络特性,因此,从商业模型出发,对业务网与承载网相分离的说法需要重新审视。Mobile and fixed networks share many technologies, so fixed networks can be taken into consideration in the discussion of core and service networks of mobile networks. The paper concludes that the IP network will become the core network of all-IP mobile networks because it adopts the nonconnection-oriented transport mode, simplifies signaling and solves problems due to the complexity of node equipment and matches the development of transmission network technologies. As to the service network of all-IP networks, the paper thinks that its design should fit packet switching networks, but be different from the simple design for the service networks of mapping array circuit switching networks. Therefore, from the business model point of view, the opinion of separating service and bearer networks needs further discussion.
