What are mobile and fixed network services?

Taking Henan Mobile customers as an example, home fixed telephone (also known as home IMS fixed telephone) service refers to the fixed telephone service that provides voice transmission through broadband (IMS) network for customers who use Henan Mobile broadband. Customers can connect the fixed telephone to the voice interface of the home gateway to realize the basic functions of the traditional fixed telephone, and at the same time, they can support the extended functions such as fax and credit card, but not the short message function. Home fixed telephone uses 8-digit fixed telephone number, and strictly implements the relevant requirements of real-name registration system. It has the functions of making long-distance calls (long-distance calls need +0, and the opening conditions are the same as those of mobile phone management when making international calls), sending and receiving faxes, caller ID, call forwarding and so on.
