A terminal and communication system

Abstract

The invention provides a terminal and a call system. The terminal includes: a communication interface, a control module and an electronic signature device interface; the electronic signature device interface is used to receive sign-in data from the electronic signature device and send the sign-in data to the control module. The data at least includes the ID of the user of the terminal; the control module is used to send the sign-in data to the communication interface; the communication interface is used to send the sign-in data out. The terminal receives the sign-in data from the electronic signature device through the electronic signature device interface, and sends the sign-in data to the server through the communication interface, so that the user only needs to carry the electronic signature device and connect the electronic signature device to any terminal, and then the same user can The ID (electronic signature device) uses different terminals to make or answer calls, realizing the flexible movement of the user's ID.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a terminal and a communication system. Background technique [0002] Under the use of the existing telephone device and communication system, the telephone user submits a registration application at the operator, and the operator allocates a network port and a corresponding number to the applicant and registers after passing the examination. Afterwards, applicants can use the telephone connected to this network port to make or receive calls. Others contact him by dialing the phone number assigned by the user. [0003] For the communication system and operating mechanism of the existing telephone, it can be seen that there are the following problems: [0004] 1. After the user registers, the port and number assigned to the applicant can only correspond to the applicant. The physical port is fixed, but the person is mobile. When he leaves the location of the phone (such as c...

AI Technical Summary

Problems solved by technology

Other people want to find this person by this fixed phone, also often need to record a plurality of fixed phone numbers (numbers such as new office phone, home landline), very inconvenient

[0005] 2. When a certain physical port and number are assigned to someone, the phone port corresponding to the number can only be used by this person

Because other people can only make outgoing calls with this number, but the port can only answer the called call of the owner of the number.

This results in a certain amount of waste of resources

[0006] 3. In addition, in the existing telephone usage situation, when you dial the other party's phone number, you cannot directly confirm whether the person answering the call is yourself. Unable to confirm whether the call is made by me

If a party to the call can imitate fraud out of malice, in the case of high security requirements, such a fixed-line device and communication system cannot meet the requirements

Moreover, the phenomenon of telephone monitoring is becoming more and more serious now, which also puts forward higher requirements for the security of telephone conversations.
