Radio reception device of the present utility model is and the identical a kind of wireless network card of standard microSD card form (size and specification).This equipment can be realized loading and removing on the microSD draw-in groove in the hand-hold type portable terminal (as mobile phone), and can independently finish the access of wireless network, can carry out the exchange of data and order simultaneously by SDIO interface and portable equipment.

Fig. 1 is the structural representation based on microSD type radio reception device and coupled hand-held mobile terminal of an embodiment of the utility model.Among Fig. 1, the transfer of data between hand-held mobile terminal 160 and the radio reception device 100 (radio reception device of microSD type) is by realizing in the microSD draw-in groove that this radio reception device 100 is loaded into this hand-held mobile terminal 160.

In introducing this radio reception device 100 in detail, before each module concrete function, at 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 that defines on the SD standard.SDIO can be mapped to a plurality of functional areas, removes general purpose I/O district (Function 0), and 7 functional areas (Function 1-7) can be arranged.

Present embodiment is mapped as Function 0 (the 0th functional areas), Founction 1 (the 1st functional areas), Function 2 (the 2nd functional areas) with the address space of this radio reception device 100.Wherein, the address space in Function 0 corresponding general purpose I/O district (general I/O area); The address space of the corresponding wireless network module 130 of Founction1; The address space of Founction 2 corresponding safe handling modules 140.

Fig. 2 is Founction 1, the Founction 2 address spaces mapping schematic diagram of an embodiment of the utility model; Wherein, left hand view is Founction 1 an address space mapping schematic diagram, and right part of flg is the address space mapping schematic diagram of Founction 2.

Among Fig. 2, the address space of the complete reproducing standards wireless LAN card of Founction 1 address space promptly adopts the address space mapping 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 a control register.This message channel (Mail Box) is the functional areas of exchange command and data.In the example, Mail Box is used to transmit random number, algorithm operation result etc.Control register is the functional areas of read-write properties and control operation.In the example, control register is used to deposit IMSI and Ki etc. is set.Wherein, this IMSI is number that the mobile subscriber distributed of unique identification in the world, can access user's cell-phone number by this number; This Ki is the key that enciphered data is transmitted between radio reception device and the common carrier.

Set forth the function and the operation principle of each module among Fig. 1 below.

Among 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 safe handling module 140.Wherein, interface processor 120 comprises SDIO equipment interface 121 and SDIO host interface 122.

SDIO physical interface 110 is physical interfaces of this radio reception device 100 and hand-held mobile terminal 160, is used for carrying out with hand-held mobile terminal 160 transmission of data and order.In the example, this SDIO physical interface is a golden finger interface.

The mobile phone signal order that SDIO equipment interface 121 in the interface processor 120 receives from hand-held mobile terminal 160 by this SDIO physical interface 110, and discern this mobile phone signal order; Be the WLAN order if identify this order, then this WLAN order sent and be sent to wireless network module 130 by this SDIO host interface 122; If identifying this order is the safety certification order, then this safety certification order is sent to safe handling module 140.

Particularly, this mobile phone signal order is SDIO order, and whether interface processor 120 is WLAN order or safety certification order by checking that Function 1 in this SDIO order and Function 2 discern this mobile phone signal order.

Wireless network module 130 can adopt traditional SDIO wireless network card, this wireless network module 130 is used to the AP (wireless access points) that makes hand-held mobile terminal 160 be connected to operator, in case connecting, this hand-held mobile terminal 160 goes up AP, then this hand-held mobile terminal 160 just can communicate with the certificate server of operator, this moment, hand-held mobile terminal 160 was linked among the WLAN of operator, but was not linked into the Internet.

Particularly, this wireless network module 130 receives from after the WLAN of interface processor 120 order, and the information according to Fouction 1 in this WLAN order is linked into hand-held mobile terminal under it in WLAN (wireless local area network) of operator.

After this hand-held mobile terminal 160 is connected to WLAN (wireless local area network), safe handling module 140 in this hand-held mobile terminal 160 by this WLAN (wireless local area network) to the certificate server request of operator to these hand-held mobile terminal 160 safety certifications, so that this hand-held mobile terminal 160 can insert Internet, concrete safety certifying method is referring to Fig. 3.

Fig. 3 is the security authentication process figure based on microSD type radio reception device of an embodiment of the utility model.

In step 310, when the user need connect Internet, at first start the client-side program of hand-held mobile terminal, this client-side program obtains the IMSI of this hand-held mobile terminal then, this IMSI is sent to the certificate server of operator again.

In step 320, certificate server is searched the Si of this IMSI correspondence from its database, 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 again.

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 the SDIO order, and then this SDIO order that comprises Function2 is sent to safe handling module 140.

In step 340, safe handling module 140 starts security algorithm after receiving this SDIO order, will be write back Mail Box by the result of calculation that this algorithm obtains then.In the example, this security algorithm is the A3 algorithm.

In step 350, interface processor 120 obtains the result of calculation that is obtained by security algorithm by SDIO interrupt notification hand-held mobile terminal 160.

In step 360, the 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, certificate server verifies according to this result of calculation whether this hand-held mobile terminal 160 has authority to insert the Internet, and after checking was passed through, this hand-held mobile terminal inserted the Internet.

Need to prove that the utility model is not limited to hand-held mobile terminal equipment, it is applicable to that all have the terminal equipment of microSD draw-in groove.

In sum, radio reception device of the present utility model has WLAN access function and safety certification function concurrently, solved and to have inserted WLAN by the wireless network card that is placed on terminal equipment, and solved the problem that to finish safety certification by the SIM/UIM card.The utility model is integrated in a physical equipment with these two kinds of functions---in the radio reception device 100, and by this radio reception device is loaded in the microSD type draw-in groove, thereby realized terminal equipment can by non-under it WLAN of common carrier be linked into Internet.

Obviously, under the prerequisite that does not depart from true spirit of the present utility model and scope, the utility model described here can have many variations.Therefore, the change that all it will be apparent to those skilled in the art that all should be included within the scope that these claims contain.The utility model scope required for protection is only limited by described claims.
