Problems solved by technology

Since the user information is stored in the RUIM card, the authentication behavior of the network to confirm the user's legitimacy can be successfully passed on the mobile phone, that is, the network cannot know the occurrence of this behavior, and the phenomenon of stealing the phone cannot be avoided.
In this way, mobile phone users unreasonably enjoy the extremely favorable call rate policy of wireless business calls, resulting in a large loss of call charge revenue for China Unicom

Embodiment 1

[0015] Embodiment 1: with reference to attached figure 1 . The machine-card integrated communication system includes a CDMA network and terminal equipment. The permanent storage area of ​​the terminal equipment is provided with two data variables Akey and SSD for authentication. Add two new variables in the permanent storage area of ​​the terminal, namely: the data Akey and SSD used for authentication, and implement the authentication algorithm in the terminal (the authentication algorithm is a prior art, which will not be described here). figure 1 Among them, when the network initiates an authentication request, the terminal uses the SSD, Akey and other parameters stored in the terminal storage area as input, outputs the authentication data through the authentication algorithm, and then sends the authentication data to the CDMA through wireless signaling Network, so as to realize the authentication process of machine card integration.

Embodiment 2

[0016] Embodiment 2: The wireless communication terminal equipment is made up of mobile phone or wireless business phone and terminal authentication software and the data backup of UIM card, is provided with Akey, SSD data variable in the permanent storage area of ​​mobile phone or wireless business phone. The mobile phone or the wireless business phone are all common mobile phones or wireless business phones sold in the market.

Embodiment 3

[0017] Embodiment 3: with reference to attached figure 2 . In the process of machine-card separation, when the network initiates an authentication request, the mobile terminal requests the RUIM to calculate the authentication data, and then the RUIM card sends the calculated authentication data to the terminal, and the terminal sends the authentication data to the network, thus completing Authentication process.

Abstract

This invention relates to an integrated communication system of computer an card and communication terminals including CDMA network and a terminal device, the permanent storage region of the terminal device is set with two data variables A key and SSD for weight authentication. When it starts a request of weight authentication, the terminal user SSD and A key stored in and other parameters as the input to output authentication data to CDMA network by authetication algorithm and wireless signaling to realize an integrated weight authentication process.

Description

Technical field: [0001] The invention relates to a machine-card integrated communication system and a communication terminal, belonging to the field of wireless communication system manufacturing. Background technique: [0002] Machine-card separation is the current standard of China Unicom's CDMA network. Terminal equipment is user-independent. All user information is stored in the RUIM card, including authentication data and authentication algorithms. The China Unicom network determines the legitimacy of the user based on the data of the RUIM card and the algorithm in the card, and the terminal device is only responsible for transmitting the data calculated by the RUIM card to the network. [0003] Wireless business calling is a new service launched by China Unicom, which is different from mobile phones. The launch of this service is for China Unicom to compete for the fixed telephone market. The characteristics of this service are: very low tariff (equivalent to fixed te...
