Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 It is a signaling diagram of an Internet access method of an Internet card in the prior art. Before the network card accesses the Internet, the USIM is first inserted into the network card through the interface corresponding to the network card, and the network card is inserted into the terminal used by the user. Such as figure 1 As shown, the method for surfing the Internet with a network card in the prior art may specifically include the following steps:

[0022] 1) The network card receives the message sent by the base station;

[0023] 2) The network card generates an application command according to the message sent by the base station, and sends the generated application command to the USIM card;

Abstract

The invention provides a wireless wide area network card and a network accessing method of the same. The wireless wide area network card comprises a chip; a modem module and a USIM (universal subscriber identity module) card are arranged in the chip; the modem module is communicated with the USIM card mutually; and the USIM card is arranged in the chip in a software way. According to the wireless wide area network card and the network accessing method provided by the invention, no entity USIM card exists in the wireless wide area network card, thus, no physical damage of the USIM card exists in the process of adopting the wireless wide area network card to perform network accessing test, and the cost for test can be effectively reduced. Moreover, no additional processes such as packaging, and replacing USIM card exist in the network accessing test process of the wireless wide area network card, thus, the test efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an Internet access card and an Internet access method for the Internet access card. Background technique [0002] The Universal Subscriber Identity Module (USIM), also known as an upgraded SIM, is a component of the Universal Mobile Telecommunications System (UMTS) 3G network. For ease of description, the USIM is generally also referred to as a USIM card in the prior art. The USIM card is usually used in the network card to realize the function of surfing the Internet. The network card can also be called a wireless wide area network card, which is used to connect to such as time division synchronous code division multiple access (Time Division-Synchronous Code Division Multiple Access; TD-SCDMA) and wideband code division multiple access (Wideband Code Division Multiple Access; WCDMA ) and other wireless wide area networks. A modulation and demodulation module is arrange...
