拨打长途电话要加拨0,从技术层面啥可不可以取消?

技术上说,是可以取消的。以往固定电话拨长途电话加0,是因为交换网络中有长途交换机,本地交换机遇0即送往长途交换机。如今移动通信发达,移动通信网已独立成网,完全可以不必加0,遇到130、189等移动通信网号直接送往移动网关局即可,这是路由组织问题,并不会如楼上所说占用更多资源。只不过固定电话网发展这么久,网络庞大,拨号规则实行很久,如果要更改,全网交换机都要重新制作局数据,工作量很大。包括通知用户更改拨号方式,工作量也是很大的。也可以说是电信业偷懒吧。

可以取消,但成本过高,用户也没有很大的需求。推荐阅读:Trunk prefixT-REC-E.123的“International prefix symbol”小节。T-REC-E.164的“International prefix”小节。T-REC-E.164的“National (trunk) prefix”小节。It is recommended by the ITU-T that the national numbering plan administrator of countries that have not yet adopted a trunk prefix for access to their national automatic trunk network adopt a prefix composed of a single digit, preferably 0. Irrespective of what digit is adopted as a trunk prefix, this digit should be precluded from being used also as a first digit of the N(S)N.The reasons for this recommendation are: – to provide the maximum degree of standardization of the national (trunk) prefixes used in different countries, so that dialling is made as easy as ossible for a person travelling from one country to another;– to minimize the number of digits to be dialled; – to reduce user problems which arise because of the requirement, in automatic international operation, that the trunk prefix of the country of destination must not be dialled.

可以取消,但是你拨号后交换机反应时间可能要增加10倍。终端交换机投资增加一倍,最终导致你话费上涨,服务体验下降。

难道不是本地通话省略了0(固话则省略0开头的地区号)吗?

加拨0说明你要出局,就直接指向他局。
