摘要
混合放号业务是固网运营商为防止客户流失而开放的一项增值业务。实现该业务是通过在固网中引入SHLR网元,将逻辑号码和物理号码相分离,使得用户的逻辑号码不变,而物理号码随着端局的变化而改变。由于物理号码对客户是透明的,因此混合放号能够让固话用户在辖区内任意移机而保持用户的使用号码即逻辑号码不发生改变。介绍利用SHLR对NP(移机不改号)业务进行改造,将NP的呼叫路由从SSP改为指向软交换,从而将NP业务割接为混合放号业务。
Hybrid number assignment is a kind of value- added service opened by fixed network operaters for preventing customers from running off. It is realized by introducing SHLR network element into PSTN. SHLR can separate logic number from physical number,make logic number of the customer unchangeable and make physical number of the customer change with Local Swithching. Because physical number is transparent to the customer, hybrid number assignment make the customers of PSTN move the telephone without changing its logic numbers in the same city. SHLR transforms Number Portability（NP） to hybrid number through changing call routing of NP from SSP to soft switch.
