Embodiment Construction

[0070] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0071] In the embodiment of the present invention, the SIM card (SIM, USIM, RUIM, UIM, etc. are collectively referred to as the SIM card in this article, which will not be described separately below) can be shared in the cloud, and can be accessed via a wireless communication network data link or the Internet. The portable wireless broadband device distributes and authenticates the SIM card, and distributes the local SIM card to the portable wireless broadband device (that is, the network roaming terminal) in the cross-border roaming so as to realize the local wireless access, and avoids the user from crossing multiple wireless networks (PLMN) High roaming charges incurred when using mobile phones to surf the Internet.

Abstract

The invention discloses a network roaming system and method and relates to the technical field of mobile communication. According to an embodiment, the network roaming method comprises the steps that a network roaming terminal establishes a wireless network communication channel with a current SIM card and has access to cloud side servers to obtain local SIM card information shared by the cloud side servers; through the local SIM card information, a wireless network communication channel for access to the internet is established; the wireless network communication channel established based on the local SIM card information provides the Wi-Fi access function for a user terminal, and therefore network roaming access of the user terminal is achieved. By the adoption of the network roaming system and method, network roaming cost is greatly reduced, the network roaming technology achieved through the network roaming system and method does not require that Wi-Fi must exists in a current network environment or a local SIM card service must be opened, the adaptability is higher, and it is only required that a location is within wireless communication network coverage.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a network roaming system and a network roaming method. Background technique [0002] At present, traveling and business outbound users have a strong need to surf the Internet anytime and anywhere when carrying portable terminals abroad. Users generally realize this by activating mobile phone data business international roaming services or purchasing local mobile operators' traffic packages locally. The former will generate high costs. International roaming charges, which are often time-consuming and require familiarity with local mobile operators, are not conducive to tight schedules. [0003] For the opening of international roaming, China Mobile and other domestic operators will remind users to turn off the data service international roaming service when opening international roaming. It can be seen that the high roaming charges that may be generated are not accept...
