In the future,mobile standard-specific core
networks may collapse horizontally and vertically.
The former means that the level of integration
with the fixed network infrastructure will be closer
to the access network,resulting in a single
radio mobile-specific packet node instead of two,
denoted enhanced mobile packet service node (EMPSN)
in the collapsed packet domain in Fig.3.
The latter means a flatter protocol suite than in
current systems like UMTS.Instead of providing
mobile standard-specific means to extend network-
layer protocols toward the mobile terminal,
mobile standard-specific mechanisms will be confined
to link-layer support.Thus,for example,the
IP layer may be directly extended to the mobile
end-user device,eliminating mobile standard-specific
tunnel and convergence protocols.Moreover,
native IP mechanisms are emerging with the
potential to substitute ATM in the UTRAN.The
resulting “cellular Internet” shares the unique
Internet infrastructure with mobile and fixed,
public and private users.
在未来的移动标准具体核心网络可能坍塌的横向和纵向.前者指一体化水平的固定网络基础设施将会更紧密地接入网络,形成一个单一的无线电移动具体分组节点不是两年,denoted增强移动包服务节点(empsn)在坍塌的包域图.3.后者是指一种恭维议定书组曲比现行制度一样的UMTS.而不提供移动标准的具体办法,以扩大网络层协议对移动终端,移动标准的具体机制将仅限于链路层的支持.因此,举例来说,IP层可直接延伸至移动终端用户装置 消除移动标准具体隧道衔接议定书.此外,本地IP机制正在出现有可能取代ATM在utran.由此产生的"移动互联网"股份独特的因特网基础设施的移动电话和固定电话,公共和私人用户.
