- #4 业务驱动： 话音业务为主 --- 〉话音，数据，多媒体业务 资源利用驱动 低成本地高效利用资源来提供业务 技术： 技术更新加快，以 VOIP 的建网成本比之 PSTN 大幅降低，今天的 NGN 语音效果以及成熟到能够取代 PSTN ； 并且可以提供大量的 PSTN 所不能够提供的业务，比如视频电话，比如广域 centrex 群…
- #5 对增值业务的支持日益显出力不从心； 对多媒体业务实现困难、运营维护管理要求高； 投资收益正在下降，形成了增量不增收的局面； 固网的先天缺陷，导致 PSTN 无法和移动通讯竞争。 在运营商中，竞争在不断的增加 VoIP 语音业务对传统话务量风流严重 移动通讯在快速的增长，对固网市场形成取代之势 基于 INTERNET 的数据业务以井喷式的发展，成为运营商新的利润增长点 增值业务的发展成为运营商竞争的焦点 这是世界性大趋势，不是靠一两招就能化解的固有风险，小灵通解决不了长远大局， 转型是唯一出路。 因此国内外的运营商都在考虑发展数据业务，希望能够分担语音业务收入下降的风险。 在运营商中，竞争在不断的增加 VoIP 语音业务对传统话务量风流严重 移动通讯在快速的增长，对固网市场形成取代之势 基于 INTERNET 的数据业务以井喷式的发展，成为运营商新的利润增长点 增值业务的发展成为运营商竞争的焦点

- #17 NGN protocols include: SIGTRAN, MGCP, H.248, H.323, SIP and ISUP. SIGTRAN protocol group is used when ss is interconnected with PSTN, over which the ISUP protocol is borne. MGCP and H.248 protocols are used for interconnection with various MGs. H.323 and SIP protocols are used for interconnection among SoftSwitch devices, and meanwhile, H.323 can also be used for interworking with H.323 media terminal, while SIP can be used for interworking with SIP terminal.

- #43 将用户号码独立出来，不再与具体设备紧密联系，将承担路由标识的功能交给了物理号码，使得放号变得非常灵活。 可以针对本地网内包括固网、 PCS 网络的用户，进行号码资源统筹规划，用户拨打电话使用的号码 DN 与业务网络、局归属没有直接关系，同一号首的不同号码可以在 PCS 网、固网以及软交换、 3G 网中任意使用。 充分利用号码资源，减少号段资源利用不充分的问题，可以有效缓解号码资源紧张的问题。 可以灵活地为用户提供个性号码，而不是用户被动选号，提升服务质量。 对于用户来说，移机、使用小灵通或者将来使用 3G ，将不必面临改号的烦恼。 统一放号带来的业务 统一放号可以为运营商优化号码分配、节约号码资源，解决 NGN 、 PSTN 网用户和 PHS 用户转网需要，同时还可为客户提供个性化服务，例如： 个性化号码 个人号码携带 移机不改号 移动办公
