Problems solved by technology

[0004] However, from the perspective of user experience, for users who currently use 2G or 3G cards, if users must change their cards to use the LTE network, it will not only bring inconvenience to users, but from the perspective of card costs, using a new card Completely replacing the old card is also a waste

Abstract

The invention discloses a method, a system and a mobile terminal for enabling a 2G or 3G mobile phone card to access an LTE network. In the solution provided by the present invention, on the mobile terminal side, use the first authentication parameter of the 2G or 3G mobile phone card to calculate and obtain the first authentication calculation value according to the authentication algorithm corresponding to the 2G or 3G mobile phone card, as input, Then according to the LTE network authentication algorithm, calculate and obtain the second authentication calculation value and send it to the mobility management entity. On the network side, the mobile management entity uses the first authentication parameter of the 2G or 3G mobile phone card extracted from the authentication database to calculate the third authentication calculation value according to the authentication algorithm corresponding to the 2G or 3G mobile phone card, as input, and then according to the LTE The network authentication algorithm calculates a fourth authentication calculation value. An authentication result is obtained by comparing the second authentication calculation value with the fourth authentication calculation value. Therefore, the problem of using different authentication algorithms in different standard networks is solved, so that users can use 2G or 3G mobile phone cards to access the LTE network without changing the card.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, a system and a mobile terminal for enabling a 2G or 3G mobile phone card to access an LTE network. Background technique [0002] The LTE (Long Term Evolution, Long Term Evolution) project is the evolution of 3G technology. As a transition between 3G and 4G technology, the LTE network improves and enhances the 3G air access technology. However, the most widely used mobile network is still 2G or 3G network. [0003] During the network upgrade process from 2G or 3G to LTE, from the perspective of the operator, the upgrade of the network requires the operator to upgrade the relevant network elements in the 2G or 3G network, and upgrade to the network elements in the LTE network . [0004] However, from the perspective of user experience, for users who currently use 2G or 3G cards, if users must change their cards to use the LTE network, it will not only bring inconve...
