Method for activating soft SIM card, method for soft SIM card to join network, terminal and network access device

A terminal, comprising:

• a reading unit, configured to read information of a soft subscriber identity module (SIM) card in the terminal, and acquire information on the terminal of a bounding object corresponding to the soft SIM card according to the information of the soft SIM card;
• an encrypting unit, configured to generate first key information according to the information of the soft SIM card and the information of the bounding object and according to a predefined encryption policy;
• a comparing unit, configured to compare whether the first key information is consistent with preset key information corresponding to the soft SIM card, wherein the preset key information corresponding to the soft SIM card is:
• key information generated according to the information of the soft SIM card and preset information of each bounding object by an operator of the soft SIM card and according to the predefined encryption policy, and provided to a user;
• an antenna, configured to transmit information to a network, and receive information transmitted by the network, wherein, the information transmitted to the network comprises:
• when the first key information is consistent with the preset key information corresponding to the soft SIM card, a network-joining request,
• wherein the soft SIM card is realized by storing all information originally set in a hard SIM in a soft SIM card file by an operator issuing the SIM card through documenting the information.

A network access device, comprising:

• a storing unit, configured to store information of a soft subscriber identity module (SIM) card, wherein the information of the soft SIM card comprises an identity of the soft SIM card, and authentication and encryption information corresponding to the soft SIM card;
• a first authenticating and encrypting unit, configured to, under control of a controlling unit, generate and transmit an encryption factor to a user, and generate network key information according to the encryption factor, the identity of the soft SIM card stored in the storing unit, and the authentication and encryption information corresponding to the soft SIM card and according to a predefined encryption policy corresponding to the SIM card, and compare whether the network key information is consistent with terminal key information fed back by the soft SIM card, and if consistent, feedback a result of authentication to the controlling unit indicating authentication passed;
• wherein the terminal key information is generated by a terminal in which the soft SIM card is located according to the encryption factor, the identity of the soft SIM card and authentication and encryption information of a second SIM card in the terminal and according to the predefined encryption policy;
• the controlling unit, configured to control the first authenticating and encrypting unit, and control an operation of an access unit according to feedback of the first authenticating and encrypting unit;
• the access unit, configured to provide network access for the SIM card under control of the controlling unit,
• wherein the soft SIM card is realized by storing all information originally set in a hard SIM in a soft SIM card file by an operator issuing the SIM card through documenting the information.
