Radio reception device of the present invention is and standard microSD card form (size and specification) identical a kind of wireless network card.This equipment can the microSD draw-in groove in hand held mobile terminals (as mobile phone) realize load and remove, and can the access of complete independently wireless network, can be carried out the exchange of data and order by SDIO interface and portable equipment simultaneously.
Fig. 1 is the structural representation based on microSD type radio reception device and coupled hand-held mobile terminal of one embodiment of the invention.In Fig. 1, the transfer of data between hand-held mobile terminal 160 and radio reception device 100 (radio reception device of microSD type) realizes in the microSD draw-in groove by this radio reception device 100 being loaded into this hand-held mobile terminal 160.
Introducing in this radio reception device 100 before each module concrete function in detail, first set forth the mapping of this radio reception device logical address space.
The interface of this radio reception device 100 is a kind of SDIO type interfaces, and SDIO is a kind of Peripheral Interface defined in SD standard.SDIO can be mapped to multiple functional areas, and removing general purpose I/O district (Function 0), can have 7 functional areas (Function 1-7).
The Address space mappinD of this radio reception device 100 is Function 0 (the 0th functional areas), Founction 1 (the 1st functional areas), Function 2 (the 2nd functional areas) by the present embodiment.Wherein, the address space in Function 0 corresponding general purpose I/O district (universal input output area); The address space of the corresponding wireless network module 130 of Founction1; The address space of the corresponding secure processing module 140 of Founction 2.
Fig. 2 is Founction 1, the Founction 2 Address space mappinD schematic diagram of one embodiment of the invention; Wherein, left hand view is Founction 1 Address space mappinD schematic diagram, and right part of flg is the Address space mappinD schematic diagram of Founction 2.
In Fig. 2, the address space of the complete reproducing standards wireless LAN card of Founction 1 address space, namely adopts the Address space mappinD of AR6002; The address space of Function 2 is divided into two parts, and a part is message channel (Mail Box), and another part is control register.This message channel (Mail Box) is the functional areas of exchange command and data.In an example, Mail Box is for transmitting random number, algorithm operation result etc.Control register is the functional areas of read-write properties and control operation.In an example, control register is used for depositing IMSI and arranging Ki etc.Wherein, this IMSI identifies for unique the number that a mobile subscriber distributes in the world, can be obtained the cell-phone number of user by this number; This Ki is the key that between radio reception device and common carrier, enciphered data is transmitted.
Set forth function and the operation principle of each module in Fig. 1 below.
In Fig. 1, hand-held mobile terminal 160 is the mobile phone terminals with microSD draw-in groove.Radio reception device 100 comprises SDIO physical interface 110, interface processor 120, wireless network module 130 and secure processing module 140.Wherein, interface processor 120 comprises SDIO equipment interface 121 and SDIO host interface 122.
SDIO physical interface 110 is this radio reception devices 100 and the physical interface of hand-held mobile terminal 160, for carrying out the transmission of data and order with hand-held mobile terminal 160.In an example, this SDIO physical interface is a golden finger interface.
SDIO equipment interface 121 in interface processor 120 receives the mobile phone signal order from hand-held mobile terminal 160 by this SDIO physical interface 110, and identifies this mobile phone signal order; If identifying this order is WLAN order, then this WLAN order is sent and be sent to wireless network module 130 by this SDIO host interface 122; If identifying this order is safety certification order, then this safety certification order is sent to secure processing module 140.
Particularly, this mobile phone signal order is SDIO order, and interface processor 120 is by checking that Function 1 in this SDIO order and Function 2 identifies whether this mobile phone signal order is WLAN order or safety certification order.
Wireless network module 130 can adopt traditional SDIO wireless network card, the AP (wireless access points) of this wireless network module 130 for making hand-held mobile terminal 160 be connected to operator, once this hand-held mobile terminal 160 connects upper AP, then this hand-held mobile terminal 160 just can communicate with the certificate server of operator, now hand-held mobile terminal 160 is linked in the WLAN of operator, but is not linked into the Internet.
Particularly, after this wireless network module 130 receives the WLAN order from interface processor 120, according to the information of Fouction 1 in this WLAN order, hand-held mobile terminal belonging to it is linked in the WLAN (wireless local area network) of operator.
After this hand-held mobile terminal 160 is connected to WLAN (wireless local area network), secure processing module 140 in this hand-held mobile terminal 160 passes through the certificate server request of this WLAN (wireless local area network) to operator to this hand-held mobile terminal 160 safety certification, so that this hand-held mobile terminal 160 can access Internet, concrete safety certifying method is see Fig. 3.
Fig. 3 is the security authentication process figure based on microSD type radio reception device of one embodiment of the invention.
In step 310, when user needs to connect Internet, first start the client-side program of hand-held mobile terminal, then this client-side program obtains the IMSI of this hand-held mobile terminal, then this IMSI is sent to the certificate server of operator.
In step 320, certificate server searches Si corresponding to this IMSI from its database, then generates a random number according to this IMSI, Si, then this random number is back to the client-side program of this hand-held mobile terminal.
In step 330, after the client-side program of hand-held mobile terminal receives this random number, this random number is written in the Mail Box of Function 2 in SDIO order, and then the SDIO order this being comprised Function2 is sent to secure processing module 140.
In step 340, after secure processing module 140 receives this SDIO order, start security algorithm, then the result of calculation obtained by this algorithm is write back Mail Box.In an example, this security algorithm is A3 algorithm.
In step 350, interface processor 120 obtains by SDIO interrupt notification hand-held mobile terminal 160 result of calculation obtained by security algorithm.
In step 360, client-side program response is interrupted, and reads this result of calculation to Mail Box, then this result of calculation is sent to the certificate server of operator by WLAN (wireless local area network).
In step 370, according to this result of calculation, certificate server verifies whether this hand-held mobile terminal 160 has permission accessing Internet, after being verified, and this hand-held mobile terminal accessing Internet.
It should be noted that, the invention is not restricted to handhold mobile terminal equipment, it is applicable to all terminal equipments with microSD draw-in groove.
In sum, radio reception device of the present invention has WLAN access function and safety certification function concurrently, solves and needs to access WLAN by the wireless network card being placed on terminal equipment, and solve the problem needing to be completed safety certification by SIM/UIM card.The present invention by these two kinds of function i ntegration at a physical equipment--in radio reception device 100, and by this radio reception device is loaded in microSD type draw-in groove, thus achieves terminal equipment and can be linked into Internet by the non-WLAN of common carrier belonging to it.Obviously, under the prerequisite not departing from true spirit of the present invention and scope, the present invention described here can have many changes.Therefore, all changes that it will be apparent to those skilled in the art that, all should be included within scope that these claims contain.The present invention's scope required for protection is only limited by described claims.
