Problems solved by technology

[0003]However, the wireless card writing terminal using the SMS channel has a wide working area, but limited by the characteristics of the SMS channel itself, the network and the wireless card writing terminal need multiple During the data interaction process, the system and users wait for a long time, and the data channel is easily blocked, resulting in the failure of the wireless card writing business
[0004]The wireless card writing terminal using GPRS channel, by using GPRS channel, greatly improves the data volume of a single data exchange between the network and wireless card writing terminal, reducing It reduces the number of interactions between the network and wireless card writing terminal, shortens the waiting time of the system and users, the data channel is not easy to be blocked, and the success rate of card writing business is high. However, this terminal can only be used in areas with GPRS resources, and cannot be used in the vast wireless GPRS resource area for wireless card writing business

Embodiment 1

[0051] Embodiment 1, multi-channel wireless card writing terminal, such as figure 1 As shown, it includes: a control module, a wireless communication module, a channel selection module, and a subscriber identification module interface module; the channel selection module is connected to the control module and the wireless communication module through wired communication or an internal interface .

[0052] In this embodiment, the subscriber identity module interface module includes a first subscriber identity module slot and a second subscriber identity module interface module;

[0053] The first subscriber identification module slot is used to connect the first subscriber identification module and the wireless communication module; the first subscriber identification module is a smart card with wireless card writing function (see Chinese patent 200710119254.5 for details). In practical applications, the first subscriber identity module may also be located at the wireless mobi...

Embodiment 2

[0077] Embodiment two, a multi-channel wireless card writing terminal includes a control module, a wireless communication module, a user identification module interface module and a channel selection module; as image 3 As shown, in this embodiment, the channel selection module is set in the control module; the wireless communication module and the subscriber identification module interface module are the same as those in Embodiment 1, the difference is that the wireless communication module needs to communicate with the control module through the Channel selection module for interaction.

[0078] In this embodiment, the structure of the control module is as follows Figure 4 shown, including:

[0079] A data I / O interface, a storage unit, a judging unit, and a data processing unit; the data I / O interface includes a first data I / O interface and a second data I / O interface.

[0080] The data processing unit is connected to the second subscriber identity module interface modul...

Embodiment 3

[0093] Embodiment three, the multi-channel wireless card writing terminal includes a control module, a wireless communication module, a subscriber identification module interface module and a channel selection module; as Figure 6 As shown, the structure of the control module in this embodiment is the same as that in Embodiment 2, such as Figure 6 As shown, the channel selection module is set in the data processing unit of the control module; the wireless communication module and the user identification module interface module are the same as in the first embodiment, the difference is that the wireless communication module needs to pass through the control module The second data I / O interface in the interface interacts with the channel selection module, and sends the card writing request data and the data returned by the wireless mobile communication server (for writing to the channel selection module) to the channel selection module through the second data I / O interface. car...

Abstract

A multichannel wireless write card terminal comprises a channel selection module, a wireless communication module and a control module, wherein, the wireless communication module is used for receiving write card request data and transmitting the write card data to the channel selection module; the control module is used for writing the received write card request data and transmitting the received write card response data to the channel selection module; and the channel selection module is used for transmitting the received write card request data to the control method and judging whether a selected data channel exists, if no, the channel selection module is used for instructing the wireless communication module to try to open all the data channels and defining the data channel which is successfully opened as the selected data channel; the channel selection module is also used for encapsulating the write card response data according to the selected data channel format and transmitting the encapsulated write card response data to the wireless communication module, for decapsulating the write card data according to the selected data channel format after receiving the write card data and transmitting the decapsulated write card data to the wireless communication module. The invention can simultaneously support a plurality of data channels at multiple levels and automatically use the optimal data channel resource to write card in a wireless way according to the network conditions.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multi-channel wireless card writing terminal. Background technique [0002] The SIM / UIM card is also called the Subscriber Identification Module. Existing wireless card writing (such as SIM / UIM card) terminals use two data channels—SMS data channel or GPRS (General Packet Radio Service, General Packet Radio Service) data channel— The one specified in - is used as a channel for terminal and network data communication, and is connected to the computer card writing terminal set up in the business hall of the wireless communication operator, and interacts and transmits data through the TCP / IP protocol to complete the card writing and SIM / UIM card Issue work. [0003] However, the wireless card writing terminal using the SMS channel has a wide working area, but limited by the characteristics of the SMS channel itself, the network and the wireless card writing terminal need mul...
