Problems solved by technology

However, this method has the following problems: First, the increase in hardware costs may easily lead to the failure of the network access test; in addition, before the network access, the user needs to download the user identification card information corresponding to the current network through the network in advance, or the user terminal is required to have enabled data international roaming However, users usually turn off the data roaming service function before leaving the country. Therefore, this method makes it impossible for users to activate roaming data localization services anytime and anywhere, and card resources cannot be dynamically recovered.

Embodiment 1

[0058] The embodiment of the present invention provides a data service transmission method, which is applied to mobile communication equipment, such as figure 1 As shown, the method includes:

[0059] Step 101: When the mobile communication device is in a roaming state, generate a first request; wherein, the first request is for the mobile communication device to manage M communication network identification cards corresponding to different roaming locations. The server obtains the card information of the identification card of the communication network corresponding to the current roaming place; the M is a positive integer;

[0060] Step 102: The mobile communication device establishes a data connection with the communication network corresponding to the current roaming location based on the card information of the first preset card;

[0061] Step 103: The mobile communication device sends the first request to the server based on the data connection to obtain the card inform...

Embodiment 2

[0077] An embodiment of the present invention provides a data service transmission method, which is applied to a mobile communication device, and the mobile communication device includes: at least one communication subunit, such as figure 2 As shown, the method includes:

[0078] Step 201: When the mobile communication device is in a roaming state, generate a first request; wherein, the first request is for the mobile communication device to manage M communication network identification cards corresponding to different roaming locations. The server obtains the card information of the identification card of the communication network corresponding to the current roaming place; the M is a positive integer;

[0079] Step 202: The mobile communication device judges whether there is an idle communication subunit, and obtains a first judgment result;

[0080] Step 203: When the first judgment result indicates that there is an idle communication subunit, load the card information of...

Embodiment 3

[0126] The embodiment of the present invention also provides a mobile communication device, such as Figure 4 As shown, the mobile communication device 40 includes:

[0127] a first control unit 401, configured to generate a first request when the mobile communication device is in a roaming state;

[0128] Wherein, the first request is for the mobile communication device to obtain the card information of the identification card of the communication network corresponding to the current roaming place from a server that manages the identification cards of M communication networks corresponding to different roaming places; The M is a positive integer;

[0129] The second control unit 402 is configured to, based on the card information of the first preset card, control the data connection unit to establish a data connection with the communication network corresponding to the current roaming place; based on the data connection, send the first request to the server , obtain the car...

Abstract

The present invention provides a data service transmission method and a mobile communication device. The method includes: when the mobile communication device is in a roaming state, generating a first request; In the identification card server in the M communication networks corresponding to the location, the card information of an identification card in the communication network corresponding to the current roaming location is obtained; the mobile communication device is based on the card information of the first preset card, and the corresponding location The communication network establishes a data connection; the mobile communication device sends the first request to the server based on the data connection, and obtains the card information of the identification card; the mobile communication device communicates with the current roaming location based on the card information of the identification card The network establishes a data connection, and executes data service transmission under the communication network.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data service transmission method and a mobile communication device. Background technique [0002] With the development of intelligent terminals and wireless network technologies, users expect to use the same terminal to access the Internet at different locations. Different locations may be covered by different communication networks, and accordingly, end users may need to pay expensive roaming data service charges for data transmission, especially in the case of international roaming. At present, there is a product on the market, which mainly realizes the localization of data charges when users roam internationally. This product is mainly realized by obtaining the key information Ki of the user identification card: [0003] An implementation method is as follows: the user prefabricates user identification cards of multiple countries in the terminal, and when ...
