Embodiment
The BIP agreement is a kind of connection-oriented host-host protocol that proposes in the 3GPP standard, and supported high-speed channel comprises GPRS, EDGE and UMTS.The theoretical speed of these three kinds of passages can reach 172Kbps, 384Kbps, 2Mbps.
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
As shown in Figure 1, apparatus of the present invention comprise: mobile network protocol module 1, host-host protocol module 2 and bearer independent protocol module 3.
Mobile network protocol module 1 is used for storage and realizes the mobile network protocol stack, and the mobile network protocol stack is the 2G/3G network protocol stack, comprises GPRS, EDGE and UMTS mobile communications network;
Host-host protocol module 2 is used for storage and realizes transport protocol stack, when using BIP and realize aerial the download, finishes mutual with far-end server as client, and the transport layer that the application transport agreement is established to described far-end server connects;
Bearer independent protocol module 3, as gateway, with between far-end server by host-host protocol communication, pass through the BIP command communication with client, encoding and decoding BIP order, set up communication channel by the BIP order with client, receive the data that client sends to far-end server by described communication channel, call transport protocol stack and mobile network protocol stack, application transport connects finishes data encapsulation, the data of described client are sent to described far-end server, and by described mobile network protocol stack, and described transport protocol stack is connected the data that the described far-end server of reception sends to described client with described transport layer, then, to client, receive data with the notice client by Application Protocol Data Unit order transmission incident, client receives this data by described communication channel.
Above-mentioned transport protocol stack can use different agreements, and for example, ICP/IP protocol, CAT_TP agreement are so that the use of carrier independent protocol is transparent for far-end server.If the application ICP/IP protocol, TCP operates in apparatus of the present invention; If use the CAT_TP agreement, CAT_TP is applied in client.
Above-mentioned client can be common SIM card, also can be smart card, as usim card, UICC card.Perhaps be multimedia storage card, and all support bearer independent protocol.
The invention described above device can be used as the functional module of mobile device (as mobile phone, PDA).When apparatus of the present invention during as the MODEM of smart mobile phone, OTA can be directly transport protocol stack by host-host protocol module 2 carry out, need not to realize by the transport protocol stack in the smart mobile phone application processor.Apparatus of the present invention also can be used as one independently MODEM be used for linking to each other with PC (personal computer) equipment, realize OTA.
In the method for the invention, client and bearer independent protocol module 3 are supported the BIP instruction, instruction comprises proactive command, as OPEN CHANNEL (opening channel), CLOSE CHANNEL (closing channel), RECEIVEDATA (reception data), SEND DATA (transmission data), GET CHANNEL STATUS (acquisition channel status), and incident, as Data available (data are effective) and Channel status (channel status), thereby between client and bearer independent protocol module 3, set up data channel.Make the bearing capacity foundation of client energy use device and the connection-oriented data channel between the far-end server.
Use the inventive method transmits data between SIM card and far-end server flow process as shown in Figure 2.
Step S201, between SIM card and bearer independent protocol module 3, set up communication channel, SIM card is used APDU (Application Protocol Data Unit, Application Protocol Data Unit) order FETCH sends proactive command OPEN CHANNEL to bearer independent protocol module 3, and bearer independent protocol module 3 sends the FETCH order that APDU order TERMINAL RESPONSE order sends with the response SIM card to SIM card; FETCH is the APDU order that is used for proactive command is sent to from smart card terminal, see ETSI TS102.221 11.2.3 joint, OPEN CHANNEL order is the BIP order in the definition of ETSI TS 102.223 6.4.27 joint, and TERMINAL RESPONSE is the APDU order in the definition of ETSI TS 102.221 11.2.4 joint.
Step S202, to bearer independent protocol module 3, bearer independent protocol module 3 is replied TERMINAL RESPONSE order with response SEND DATA order to SIM card by SEND DATA command sending data; The SENDDATA order is the BIP order in the definition of ETSI TS 102.223 6.4.30 joint.
During step S203, host-host protocol module 2 is set up according to the host-host protocol of using and is connected with the transport layer between far-end server, bearer independent protocol module 3 application transport protocol stacks are connected with transport layer, and the data channel of setting up by mobile network protocol module 1 sends the data to far-end server;
Step S204, by the data channel that mobile network protocol module 1 is set up, host-host protocol module 2 receives from far-end server according to the host-host protocol of using and sends to the data of SIM card to bearer independent protocol module 3;
Step S205, bearer independent protocol module 3 sends APDU order ENVELOPE so that the Dataavailable event notice arrives SIM card, and SIM is known can receive data; The ENVELOPE order is to be used for data are sent to the APDU order that resides in the application program on the SIM card, in the definition of ETSI TS 102.2217.4.2.2 joint.
Step S206, SIM card uses RECEIVE DATA order to obtain data from bearer independent protocol module 3, and bearer independent protocol module 3 is used TERMINAL RESPONSE command response RECEIVE DATA order, and sends data to SIM card.RECEIVE DATA order is the BIP order in the definition of ETSI TS 102.223 6.4.29 joint, is used to receive the data of far-end server, finishes OTA and downloads.
Fig. 3 and Fig. 4 have provided two embodiment of differing transmission protocols.
Fig. 3 is based on the BIP system architecture schematic diagram of the use Transmission Control Protocol of GPRS/EDGE/UMTS, TCP is applied to respectively on apparatus of the present invention and the far-end server, SIM card is utilized the TCP safety between apparatus of the present invention and the far-end server to connect and is received and send data by BIP, uses the mobile network and carry data between physical layer apparatus of the present invention and far-end server.
Fig. 4 is based on the BIP system architecture schematic diagram of the use CAT_TP agreement of GPRS/EDGE/UMTS, CAT_TP is a kind of host-host protocol, regulation in ETSI TS 102.127, be applied between SIM card and the far-end server, the CAT_TP agreement allows SIM card to be established to the data channel of far-end server, and the exchanges data between apparatus of the present invention and the far-end server is passed through udp protocol.Udp protocol can not guarantee the integrality and the sequential delivery of data, and packet may out of order arrival or lost, and CAT_TP guarantees the reliable transmission of data between SIM card and far-end server as the support to UDP.CAT_TP realizes on SIM card and far-end server.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
