Description
Technical Field
The present invention relates to the field of distributed network telephones, and more particularly, to a distributed network mobile telephone (DHP) user management method and management card.
Background
A distributed network is formed by interconnecting node machines that are distributed at different locations and have multiple terminals. Any point in the network is connected with at least two lines, when any line has a fault, communication can be completed through other links, and the reliability is high. At the same time, the network is easily scalable. Therefore, it becomes a topology structure commonly used in the wide area network, the application range is wider and wider, and the mobile communication using the distributed network is mature, but the telephone is currently used as a management object as a communication system.
In the distributed network communication system, the inventor has found through analysis that if the user identification information and the operation unit can be made in the management card, the management card and the distributed network mobile phone can be separated, and the distributed mobile phone has universality.
To this end, the inventor intends to develop a network mobile phone user management method, which is to provide a management card and an application method thereof to a distributed network mobile phone (DHP) dedicated user so as to manage the user using the distributed network mobile phone.
Disclosure of Invention
In order to solve the above problems, the present invention provides a method for managing a user of a distributed network mobile phone and a management card thereof, so as to separate the management card from the distributed network mobile phone and make the distributed network mobile phone have universality.
The invention provides a distributed network mobile phone user management card, which comprises three parts: the device comprises an arithmetic unit with a storage function, a data bus, a power line and a ground line, wherein an asymmetric encryption algorithm program is stored in a ROM in the arithmetic unit. When the management card is installed in the mobile telephone set, the user management card can obtain power supply from the telephone set through the power line, and at the moment, the asymmetric encryption algorithm in the ROM in the operation unit can be called into the RAM of the MCU to start operation, and a public key and a private key are obtained. The public key can be used as a unique device ID identification of the mobile phone, and the private key can enable a user node where the management card is located to view encrypted communication information.
The invention also provides a user management method of the distributed network mobile phone applying the user card, which comprises the following steps:
step 1: obtaining a public key and a private key from a management card of a distributed network mobile phone, and storing the public/private key pair into a flash of the distributed mobile phone;
step 2: the public key is used as the unique equipment ID identification of the mobile phone, and is simultaneously broadcast to all network mobile phone nodes in the distributed network for addressing and node communication information encryption, and the user node checks the encrypted communication information by means of the private key;
and step 3: the management card of the distributed network mobile phone is accessed to the network to obtain the IP of the network, the network IP and the equipment ID of the mobile phone are operated to generate a random number as the random addressing address IP of the network mobile phone, the value of the random addressing address IP can randomly change along with the position of the network mobile phone, all the changed values are stored in nodes participating in network communication as distributed addressing parameters to form a distributed addressing parameter table, and the distributed addressing parameter table is distributed and stored in network nodes.
Further, when the method is used for communication, the network mobile phone A firstly sends a call request to the network mobile phone B, and the following operations are carried out at the moment:
s1: if the communication opposite end B and the call initiating end A are detected to be under the same IP, the equipment ID (public key) of the opposite end B is directly found out to send a findnode request instruction, and if the instruction is received by the B, the response module returns a state value to the A, and the A and the B establish network connection. If A does not receive the return state value of B, then B is judged to be in an off-line state, and the communication connection request is cancelled. If the opposite communication end is offline in the distributed network communication, the communication connection can not be established. In communication, information sent by A to B is encrypted by the public key of B, and B looks for the private key of B, or vice versa.
S2: if the communication opposite terminal B and the call initiating terminal A are detected not to be under the same IP, the call initiating terminal A sends a findnode request, the request starts to search all dynamic random addressing parameters IP of the communication opposite terminal B from a node closest to the call initiating terminal A, and after the request is received by the call initiating terminal A, a response module returns a state value to the call initiating terminal A, and the call initiating terminal A and the call initiating terminal B establish connection. If A searches all nodes and does not get the response of B, then it is determined that B is in off-line state and the communication request is cancelled.
The invention has the advantages that by means of the technical scheme, the separation of the management card and the distributed network mobile phone can be realized, so that the distributed mobile phone has universality and better customer experience can be provided.
