Summary of the invention
Coffret between mobile phone and SIM card is the smartcard-Terminal equipment interface of standard, namely meets the interface of ISO-7816 smart card host-host protocol.In Wireless Data Transmission between mobile phone and SIM card, except being except wave point between communication terminal interface equipment and intelligent SIM card deck equipment, at the two ends of radio communication, be namely all the interface of the ISO-7816 smart card host-host protocol of standard between communication terminal interface equipment and mobile phone and between intelligent SIM card deck equipment and SIM card.That is, relative to mobile phone, communication terminal interface equipment is exactly a SIM card; And relative to SIM card, intelligent SIM card deck equipment is exactly a mobile phone.One between mobile phone and SIM card complete data exchange process (being called an order session cycle) initiates order by mobile phone to start, and terminate the response reply of order with SIM card.So in an order session cycle, mobile phone is main equipment, and SIM card is from equipment.
Between mobile phone and SIM card the order session cycle transfer of data in, according to the host-host protocol ISO-7816 of smartcard-Terminal equipment interface, an initial bits position is had at the information byte of each transmission, indicate the beginning of an information byte (8 bits), and in the end of transmission of each information byte, there is a check bit position, for the transmission correctness of checking information byte.If the information byte of transmission has error of transmission, need again to transmit this information byte immediately.And in Wireless Data Transmission between mobile phone and SIM card, because radio transmitting method of the present invention has had other transmission error detection method, this check bit position just has not needed to be transmitted by wireless communication link.And in a Wireless Data Transmission bag, an information byte just can be transmitted in every 8 bits position, do not need special initial bits position to indicate the beginning of each information byte.Like this, ten bits originally are just reduced to 8 bits position, improve the efficiency of Wireless Data Transmission.After wireless data packet is received, then initial bits position and check bit position are inserted beginning and the end of each information byte, write to receiving terminal by the circuit connecting interface of contact, reduce the transfer of data of smartcard-Terminal equipment interface.
Fig. 1 is that mobile phone starts to initiate order session, to the formation of the wireless data packet of SIM card wireless transmission order, and transmission, and the schematic diagram received.At mobile phone terminal, when mobile phone starts to send order to SIM card, just read this order (totally five bytes) by the smartcard-Terminal equipment interface (ISO-7816 smart card host-host protocol) of standard at the communication terminal interface equipment of SIM card slot.In whole order reading process, communication terminal interface equipment detects initial bits position and the check bit position of each information byte, and processes error of transmission possible between them.If there is the information byte of error of transmission, just feed back to mobile phone, allow mobile phone again transmit this byte.After mobile phone is transmitted, be just in wait state, wait for that SIM card is replied the response of this order.After communication terminal interface equipment receives a complete order, remove initial bits position and the check bit position of each information byte, only retain its information byte, and add the error correction coding of wireless transmission in the ending of order data, just constitute a complete wirelessly transmitting data bag.By wireless transmission interface, command packet is transferred to intelligent SIM card deck equipment.The error correction coding of wireless transmission can use wireless channel coding techniques ripe in prior art, such as cyclic redundancy check (CRC) code (CRC, or forward error correction coding (FEC, ForwardErrorCorrection) etc. CyclicRedundancyCheck).
Intelligent SIM card deck equipment receives command packet, obtained the information byte of correct order data by the error correction decoding of wireless transmission after, just each information byte start add initial bits position, check bit position is added in the end of each information byte, and pass through the smartcard-Terminal equipment interface (ISO-7816 smart card host-host protocol) of standard, forward this order data of transmission to the SIM card being inserted in its SIM card slot.In the process to SIM card command data, the error of transmission of intelligent SIM card deck device processes between them, if there is the information byte of error of transmission, just transmits this information byte again.
Equally, when intelligent SIM card deck equipment transmits the data of reply response of SIM card to communication terminal interface equipment, also be in wireless transmission process, remove each information byte initial bits position and check bit position, and the error correction coding of wireless transmission is added in the ending of replying response data, form a complete wirelessly transmitting data bag, then be transferred to communication terminal interface equipment by wireless communication interface.
By the standard intelligent card-terminal device interface at wireless transmission two ends, in the process of wireless transmission, according to the transmission needs of wireless channel, both unnecessary initial bits and check bit had been eliminated, again error correction coding is carried out to wireless data packet, while the reliability improving wireless transmission, improve the efficiency of wireless transmission.

Obtain in the process of SIM card data at communication terminal interface equipment as above by wireless communication interface, if start failure in access network also sets up wireless communication link with intelligent SIM card deck equipment at mobile phone, need reading SIM card data from its memory, these SIM card data have been stored in the memory of communication terminal interface equipment.Because mobile phone can use different SIM card data access cellular mobile networks, therefore communication terminal interface equipment is when correctly receiving the SIM card data that intelligent SIM card deck device transmission is come, just upgrade the SIM card data in its memory, with prepare may use next time (when mobile phone power-on be reading SIM card data set up wireless communication link failure time).When each communication terminal interface equipment receives SIM card data, attend school the data of label taking will SIM card uniqueness, such as ICCID, IMSI etc., and compare with its SIM card data stored in memory.If the data received are consistent with the data in memory, in the access of ensuing cellular network, just use (or in memory, because data are all the same) the SIM card data received.If the data in the SIM card data received and memory are inconsistent, then show that the SIM card in intelligent SIM card deck equipment and the SIM card data before mobile phone are different, mobile phone just uses the SIM card data access cellular network received, and upgrades the SIM card data in its memory.Like this, when mobile phone needs the SIM card data used in its memory next time, the SIM card data be updated just are used.Due under normal circumstances, user changes when using different SIM card limited, and the number of times that this SIM card data upgrade in the memory of communication terminal interface equipment is also limited.
In the process of mobile phone access cellular mobile network, not all data stored in SIM card all need.In SIM card application protocol, an elementary cell of the data stored in SIM card is called constituent instruments (EF, ElementaryFile), these constituent instruments are necessary file (Mandatory) a bit, and some is optional file (Optional).Concrete SIM card data file class defines in relevant SIM card application protocol standard, such as, 3GPPTS51.011 define the constituent instruments in the SIM application protocol of gsm system, 3GPPTS31.102 defines the constituent instruments in USIM application protocol, and 3GPP2C.S0023-A defines the constituent instruments in the UIM application protocol of cdma system.Communication terminal interface equipment of the present invention is in the Wireless Data Transmission with intelligent SIM card deck equipment, and just only transmitting these must the constituent instruments of file access for the cellular radio of mobile phone.For optional file, after communication terminal interface equipment receives the order of mobile phone reading SIM card data file, be first read from its memory, then obtained from intelligent SIM card deck equipment by wireless communication interface.And when wireless acquisition SIM card data failure time, can direct answering mobile phone message, indicate these SIM card constituent instruments not exist (replying SIM card state directive command 0x6a, 0x82).Because the SIM card data that mobile phone reads are optional constituent instruments, this can not have influence on the cellular radio access of mobile phone, after mobile phone successfully accesses cellular radio, again can also obtain the SIM card data of these optional constituent instruments from wireless communication interface.
Fig. 5 is the flow chart that communication terminal interface equipment of the present invention receives the order of mobile phone reading SIM card data file, includes following steps and treats necessary constituent instruments and optional constituent instruments respectively:
1. communication terminal interface equipment receives the order of mobile phone reading SIM card constituent instruments data.
If the SIM card constituent instruments that 2. mobile phone needs read are the necessary files in SIM card file system, communication terminal interface equipment judges whether this reading order is the SIM card data reading necessary file first time.
3., if the SIM card data of the necessary file of first time reading, communication terminal interface equipment, just according to flow process as shown in Figure 4, by wireless communication interface, obtains the SIM card data of all necessary constituent instruments once from intelligent SIM card deck equipment.
4. read the SIM card data of necessary file if not first time, the SIM card data (because all necessary constituent instruments SIM card data are read by wireless communication interface must obtain from intelligent SIM card deck equipment during file in first time) of the necessary constituent instruments required for communication terminal interface equipment just reads from its memory.
If the SIM card constituent instruments that 5. mobile phone needs read are the optional files in SIM card file system, communication terminal interface equipment is just according to the necessary constituent instruments data of wireless receiving, the data of judgement symbol SIM card uniqueness, whether the SIM card data that such as ICCID, IMSI etc. have stored in memory with it are consistent.
6., if consistent, communication terminal interface equipment is just direct reads optional constituent instruments data, for the SIM card file reading order of answering mobile phone from its memory.
7., if inconsistent, first communication terminal interface equipment is just attempted by wireless communication interface, obtains the SIM card data of this optional file from intelligent SIM card deck equipment.
If 8. the wireless communication link with intelligent SIM card deck equipment successfully set up by communication terminal interface equipment, just by wave point, obtain the SIM card data of this optional file from intelligent SIM card deck equipment, and store in its memory.
If 9. communication terminal interface equipment obtains the SIM card data failure of this optional file by wave point, just direct answering mobile phone message " this file does not exist " (replying SIM card state directive command 0x6a, 0x82).
(location updating of mobile phone in moving process is also comprised in the process of mobile phone access cellular radio communication network, and the service authentication etc. in business use procedure), mobile phone will send to SIM card authentication order (Authenticate, 0x88).This authentication order is merely able at SIM card internal operation, can not be read out by intelligent SIM card deck equipment for the KI of authentication order and authentication password algorithm, because according to network access security controlling mechanism, any external equipment all can not read the secure data of these authentications, is merely able in SIM card inner by SIM card self reading use.Therefore, when authentication order initiated by mobile phone time, communication terminal interface equipment is merely able to pass through wireless communication interface, the input data random number sequence of transmission authentication order and authentication order gives intelligent SIM card deck equipment, in the order of SIM card internal operation authentication, and the operation result data of wireless acquisition authentication order.In the session cycle of whole authentication order, mobile phone and SIM card will carry out exchanges data repeatedly.In order to reduce the number of times at wireless communication link transmitting data, the present invention is also included in the two ends of radio communication, namely carry out data buffer storage respectively in communication terminal interface equipment and intelligent SIM card deck equipment, and wait the data transmitting authentication order more in the lump when needed.
