International roam card network authentication system and method

Abstract

The invention provides an international roam card network authentication system and method. The international roam card network authentication method comprises the following steps: presetting resources of the domestic common code number and the code number of the roaming country or area; restarting or resetting the mobile phone terminal, and obtaining the standard file of the current number to perform network authentication; judging whether the network is successful or not; if the network is not successful, using the common code number with the international roaming function to perform the coverage of the authentication data; performing the reset operation to trigger the mobile phone to read the authentication file again for the network; and obtaining the MCC of the current network, and triggering the switching of international roaming resources. The invention also provides an international roam card network authentication system; by means of the international roam card network authentication system, the cheap expenses of the roaming area can be used without changing the number, therefore, the operating costs of the operator is effectively reduced, and the network efficiency of the user, the generalization performance and the suitability is improved.

Description

technical field [0001] The invention relates to the field of telecommunication smart cards, in particular to an international roaming card network authentication system and method. Background technique [0002] With the rapid growth of demand for traveling abroad, business trips, family visits, etc., overseas users have a huge demand for how to use cheap local telecom tariffs without changing the card after going abroad or returning home. . [0003] However, the current requirements for international roaming services generally have the following problems: [0004] 1. The user does not need to change the card or number, but it is necessary to activate the international roaming function of the current main number in China in advance, and at the same time use the relatively expensive international roaming tariff in the roaming area, and need to pay a part of the international roaming deposit in advance; at the same time, for the provided Operators of international roaming bus...

AI Technical Summary

Problems solved by technology

[0004] 1. The user does not need to change the card or number, but it is necessary to activate the international roaming function of the current main number in China in advance, and at the same time use the relatively expensive international roaming tariff in the roaming area, and need to pay a part of the international roaming deposit in advance; at the same time, for the provided Operators of international roaming business, due to the delay in the settlement of roaming charges, there is a greater risk of arrears; this method is not the best solution for users and operators;

[0005] 2. The user can change the card and number, and use the code number resources provided by the local operator; this method is very inconvenient for the user. If you need to roam in multiple countries or regions within a period of time, you need to purchase multiple local telecom card, which is a great waste of resources and is not convenient for users to use;

[0006] 3. Some companies have launched international roaming cards, which preset an international roaming number that basically covers mainstream countries and regions as the main communication number, but such international roaming cards cannot be integrated with the main number normally used by users in China , and need to pay more expensive code number occupation fee, the use cost is high, and is subject to the operator who provides the international roaming main number; at the same time, every time you log in and authenticate, you need to use the international roaming main number to log in first, and then If switching is performed, the overall login efficiency is low, and user perception is poor;

[0007] 4. At the same time, the international roaming cards launched by some enterprises support automatic switching of roaming destinations, and use the code number resources of the roaming destinations to log in to the Internet, but the switching method is not compatible with mainstream IPHONE terminals

[0008] The above problems cannot provide an effective solution for both the user side and the telecom operator side, which greatly restricts the development of international roaming services
