Subsystem):在IP多媒体会话上提供IP多媒体应用的所有核心网元。IP多媒体应用:同时处理一个或多个媒体的应用。语音、音频、视频、数据（文字聊天，共享白板）用户感觉同步的方式多方，多连接，加入和取消资源一个用户可在一个IP多媒体会话中同时调用多个IP多媒体应用IP多媒体会话:一组多媒体发送和接收者，以及从发送者到接收者的数据流。一个用户可同时调用多个IP多媒体会话由IMS支持需要IP连接性承载IP多媒体业务:一个或多个IP多媒体应用所提供的用户体验。,C,hi,at,All

P-CSCF和PDSN/GGSN的位置3GPP2 IMS信息放在UE，正在引入合一的UICC+ISIM(可选)临时公共/私有标识 PDSN在拜访网络，P-CSCF在归属网3GPP对没有ISIM应用的终端使用临时公共/私 3GPP的P-CSCF发现采用GPRS过程，或DHCP有标识3GPP2不使用临时标识3GPP中GGSN作为接入点在一次IMS会话中始3GPP IMS支持IPv6，IPv4可选 终不变3GPP2 IMS支持IPv6和IPv4 3GPP2中PDSN是可以改变IPv6和IPv4网络间的互操作通过IP网关 3GPP2采用不同的策略决策接口(3GPP Gq)网络安全 计费 AKA接入鉴权在3GPP和3GPP2是相同的 3GPP IMS的计费设备是CCF，3GPP2是AAA 3GPP2定义了与其他IP网络的安全接口(SA6,SA7)与接入网络相关
