After obtaining radio frequency link, the second modulation /demodulation module can be sent out by the second communication network to the server Card release request, card request is for applying for the user identifier card under third communication network, and the server is according to the request point The second modulation /demodulation module (S322) is sent to third user identifier card, and by the card information of the third user identifier card.It wants Note that the second modulation /demodulation module may repeatedly interact the card that could obtain distributed third user identifier card with server Information.Moreover, during the second modulation /demodulation module is interacted with the server, if the first modulation /demodulation module has Urgent need and will use the radio frequency link, then the second modulation /demodulation module can also suspend the interaction with server.
Second modulation /demodulation module is after the card information for receiving third user identifier card, by the user identifier card Card information is loaded into selected modulation /demodulation module (S323).For example, the card information can be stored to selected tune Memory in demodulation module processed or by card information storage to the memory with selected modulation /demodulation module couples, As long as selected modulation /demodulation module is able to use the card information of the third user identifier card.
It is only the example for obtaining the card information of third user identifier card shown in Fig. 4.Alternatively, mobile communication equipment may be used also To obtain the card information of the third user identifier card from server in advance before roaming into roaming place.
After S320, selected modulation /demodulation module is connect by the radio frequency link with third communication network communication The authentication request narrowed to the card information, and the second modulation /demodulation module (S330) is sent by the authentication request.As Example, selected modulation /demodulation module (for example, first modulation /demodulation module) obtain the radio frequency link, and by third user The card information of tag card sends third communication network to.Third communication network is after receiving card information, for the sake of security, Need to identify the right of the use of the mobile communication equipment third user identifier card, and therefore can be to selected modulatedemodulate mode transfer Block sends authentication request.The effect of authentication is protection third communication network, prevents it from illegally usurping, and refuses to palm off legitimate client " invasion " third communication network.
The authentication request for example may include a pseudo random number.Third communication network for example stores in the verifying equipment of Fig. 2 The random number, the authentication key of third user identifier card and the authentication information obtained based on the pseudo random number and authentication key. The authentication key of third user identifier card for example can the strict protection in the physical entity of third user identifier card, cannot be by Tripartite illegally obtains, and only has the legitimate user of third user identifier card to know the authentication key in this way, and can receive The authentication information is calculated after the pseudo random number.When third communication network judges the authentication information that it is stored and from shifting When the dynamic received authentication information of communication equipment is consistent, that is, it can determine whether that mobile communication equipment is the legal use of third user identifier card Person.
Refer again to Fig. 4.It is obtained using step S331, S332, S333 and S334 in Fig. 4 for third user identifier card Card information authentication request.As shown in figure 4, the second modulation /demodulation module is made to discharge the radio frequency link (S331)；It will be described Radio frequency link distributes to selected modulation /demodulation module (S332)；Selected modulation /demodulation module passes through the radio frequency link The card information of the user identifier card is sent to third communication network (S333)；Selected modulation /demodulation module passes through described Radio frequency link receives the authentication request (S334) for being directed to the card information from third communication network.
As described above, three modulation /demodulation modules share a radio frequency link.It is authenticated to be obtained from third communication network Request, it is necessary to first ensure that selected modulation /demodulation module obtains radio frequency link, it is selected by above-mentioned S331 and S332 Modulation /demodulation module obtain radio frequency link, so as to third communication network communication to obtain authentication request.Selected tune The card information of third user identifier card is sent to third communication network (S333) by the radio frequency link by demodulation module processed, with Request accesses the third communication network.Third communication network sends the authentication request, to identify mobile communication equipment to third The use right of user identifier card.Selected modulation /demodulation module is after obtaining authentication request, via the second modulation /demodulation Module obtains authentication information.
In S340, the second modulation /demodulation module obtains authentication letter by the radio frequency link and the server communication Breath, sends the authentication information to selected modulation /demodulation module.As an example, described in the acquisition of the second modulation /demodulation module The authentication request is encapsulated into the data transmitted under the agreement of the second communication network by radio frequency link, and logical via second Communication network sends the server for managing the user identifier card under third communication network to.It include pseudo random number identifying request In the case where, which for example can execute pre-defined algorithm to the authentication key of pseudo random number and third user identifier card and obtain One number of responses, the number of responses are the authentication information.Second modulation /demodulation module is receiving the authentication from server After information, the authentication information is transmitted to selected modulation /demodulation module.
Fig. 5 is schematically illustrated in the data business transmission method in Fig. 3 and is completed verifying based on authentication request to execute The flow chart of the process of data traffic transmission.Institute is obtained from server using step S341, S342, S343, S343 in Fig. 5 State authentication information.As shown in figure 5, selected modulation /demodulation module is made to discharge the radio frequency link (S341)；By the radio frequency Link distributes to the second modulation /demodulation module (S342)；Second modulation /demodulation module utilizes the radio frequency link by the mirror Power request is sent to the server, which is based on the authentication request and obtains authentication information (S343)；Second modulatedemodulate Mode transfer block receives the authentication information (S344) from the server using the radio frequency link.
Since three modulation /demodulation modules share a radio frequency link, in order to obtain the second modulation /demodulation module from server Take authentication information, it is necessary to first ensure that the second modulation /demodulation module obtains radio frequency link.By above-mentioned S341 and S342, described Two modulation /demodulation modules obtain radio frequency link, so as to logical via the second communication and server in S343 and S344 Letter is to obtain authentication information.During the second modulation /demodulation module obtains authentication information from server, it may occur however that first Modulation /demodulation module needs the case where using radio frequency link, and the second modulation /demodulation module may need to suspend the friendship with server Mutually.
In S350, selected modulation /demodulation module sends the authentication information to third using the radio frequency link Communication network is to access the third communication network.As an example, selected modulation /demodulation module obtains the radio frequency link, it will The authentication information is encapsulated into the data transmitted under the agreement of third communication network, and sends for example shown in Fig. 2 test to Demonstrate,prove the access right of equipment third user identifier card.
Referring again to Fig. 5, believed using step S351, S352, S353 in Fig. 5 to authentication described in third communication transmission of network Breath.As shown in figure 5, the second modulation /demodulation module is made to discharge the radio frequency link (S351)；The radio frequency link is distributed into institute The modulation /demodulation module (S352) of selection；Selected modulation /demodulation module is passed the authentication information using the radio frequency link Give third communication network (S353).
Similarly, three modulation /demodulation modules share a radio frequency link, in order to make selected modulation /demodulation module to Third communication transmission of network authentication information, it is necessary to first ensure that selected modulation /demodulation module obtains radio frequency link.By above-mentioned S351 and S352, selected modulation /demodulation module obtains radio frequency link, so as to S353 using the radio frequency link with Third communication network communication is to transmit authentication information.
Verifying equipment in third communication network, will after receiving the authentication information from the first modulation /demodulation module Received authentication information be compared with the authentication information that it is stored.If the two is identical, the verifying equipment confirmation The validity of the third user identifier card.
After the validity that third user identifier card has been determined, selected modulation /demodulation module just utilizes the radio frequency Link executes the data traffic transmission under the third communication network.Since the third user identifier card is in third communication network User identifier card, so saving roaming data traffic rate.
In the case where having selected third modulation /demodulation module in S310, third modulation /demodulation module can be used as above-mentioned Selected modulation /demodulation module is communicated with the second modulation /demodulation module and third communication network.Alternatively, being selected in S310 In the case where having selected third modulation /demodulation module, the first modulation /demodulation module and the first communication network can also be utilized from server It obtains card information and authentication information, third modulation /demodulation module is communicated with third communication network to be registered to third communication net Network.
For voice service, the data volume to be transmitted in data service is very big, and modulation /demodulation module is logical Run high-grade protocol stack often to execute data traffic transmission.As described above as can be seen that being connect in mobile communication equipment During entering third communication network, it is a small amount of that the second modulation /demodulation module is mainly used for transmitting authentication request and authentication information etc. Data, the data business volume transmitted are seldom.Therefore, the second modulation /demodulation module can support inferior grade protocol stack, for example, can Only to support the protocol stack under second generation communication network.The first modulation /demodulation module or third modulation /demodulation module are due to wanting The data traffic transmission under third communication network is executed, can support high-grade protocol stack, for example, can support that the second generation is logical Protocol stack under communication network and third generation communication network, or even can also support the protocol stack under forth generation communication network.In this way, The hardware cost of mobile communication equipment can be saved.Certainly, the first modulation /demodulation module, the second modulation /demodulation module and Three modulation /demodulation modules can all support high-grade protocol stack.
In the technical solution according to the above-mentioned data traffic transmission of the embodiment of the present application, load in a mobile communication device The card information of the third user identifier card of third communication network, and the user identifier card is registered to third communication network, from And the user identifier card of the communication network of roaming place is had registered in the case where the physical entity of no user identifier card.This makes The mobile communications network that mobile communication equipment can be conveniently used roaming place carries out data traffic transmission, to save roaming number According to service tariff.Since three modulation /demodulation modules share a radio frequency link, so the hardware for reducing mobile communication equipment is matched The requirement set.Moreover, while registering user identifier card in third communication network, do not need to deactivate in the first communication network and The business transmission of existing user identifier card under second communication network.

Second modulation /demodulation module 630 can obtain the card letter of the user identifier card in third communication network by operating as follows Breath: the radio frequency link is obtained according to the instruction of the first link of the control module 650, is based on the radio frequency link from the service Device receives the card information of the user identifier card, is indicated according to the load of the card of the control module 650 by the user identifier card Card information be loaded into selected modulation /demodulation module.In a particular application, control module 650 can be each modulation /demodulation The business setting priority or timing for the operation that module is carried out using the radio frequency link, however according to set priority or Timing is sequentially to control each modulation /demodulation module to use the radio frequency link.In the second modulation /demodulation module 630 according to institute After the first link instruction acquisition radio frequency link for stating control module 650, the second modulation /demodulation module 630 can be logical by second Communication network issues card request to the server, which requests for applying for the user identifier card under third communication network.It is described Server distributes third user identifier card according to the request, and the card information of the third user identifier card is sent to the second tune Demodulation module 630 processed.
During the second modulation /demodulation module 630 is interacted with the server, if control module 650 is selected Modulation /demodulation module has urgent need and to use the radio frequency link, then the control module 650 can control the second tune The interaction of demodulation module 630 pause and server processed.Second modulation /demodulation module 630 is in the card for receiving third user identifier card After information, the card information is stored to the memory in selected modulation /demodulation module or stores the card information To the memory with selected modulation /demodulation module couples, as long as selected modulation /demodulation module is able to use third use The card information of family tag card.
After the second modulation /demodulation module 630 receives the card information of the user identifier card, mobile communication equipment In modules operate as follows with from third communication network receive be directed to the card information authentication request.The control module 650 control the second modulation /demodulation modules 630 discharge the radio frequency link, and send the to selected modulation /demodulation module The instruction of two links.Since selected modulation /demodulation module and the second modulation /demodulation module 630 share a radio frequency link, so In order to obtain authentication request from third communication network, it is necessary to first ensure that selected modulation /demodulation module obtains radio frequency link, because This described selected modulation /demodulation module obtains radio frequency link under the control of control module 650.Selected modulation /demodulation Module obtains the radio frequency link according to the instruction of the second link, is sent out the card information of the user identifier card by the radio frequency link Give third communication network.Third communication network is after receiving card information, for the sake of security, needs to identify mobile communication The right of the use of the equipment third user identifier card, and therefore authentication request can be sent to the first modulation /demodulation module.Therefore, After the card information is sent to third communication network by selected modulation /demodulation module, also by the radio frequency link from Third communication network receives the authentication request for being directed to the card information, to realize authentication.
Authentication request for example may include a pseudo random number.Third communication network is for example verified at it and stores this in equipment at random Number, the authentication key of third user identifier card and the authentication information based on the pseudo random number and authentication key acquisition.Third is used The authentication key of family tag card for example can the strict protection in the physical entity of third user identifier card, cannot be non-by third party Method obtains, and only has the legitimate user of third user identifier card to know the authentication key in this way, and can receive the puppet The authentication information is calculated after random number.When third communication network judges the authentication information that it is stored and from mobile communication When the received authentication information of equipment is consistent, that is, it can determine whether that mobile communication equipment is the legitimate user of third user identifier card.
After selected modulation /demodulation module is received for the authentication request of the card information, authentication request is sent out It is sent to the second modulation /demodulation module 630, to obtain authentication information by the second modulation /demodulation module 630.In mobile communication equipment Modules operate as follows with from server obtain receive authentication information.The control module 650 controls described selected Modulation /demodulation module discharges the radio frequency link, and sends the instruction of third link to the second modulation /demodulation module 630.Due to each Modulation /demodulation module shares a radio frequency link, and the control module 650 sends the instruction of third link so that the second modulation /demodulation Module obtains radio frequency link.Second modulation /demodulation module 630 obtains the radio frequency link according to the instruction of third link, by described The authentication request is sent to the server by radio frequency link, and using the radio frequency link from described in server reception Authentication information, the server are based on the authentication request and obtain authentication information.For example, the second modulation /demodulation module 630 can be with The authentication request is encapsulated into the data transmitted under the agreement of the second communication network, and is transmitted via the second communication network To the server for managing the user identifier card under third communication network.In the case where identifying request includes pseudo random number, The server for example can execute pre-defined algorithm to the authentication key of pseudo random number and third user identifier card and obtain a response Number, which is the authentication information.Second modulation /demodulation module 630 from server receive the authentication information it Afterwards, the authentication information is transmitted to selected modulation /demodulation module.It is obtained in the second modulation /demodulation module 630 from server During authentication information, it may occur however that the case where selected modulation /demodulation module is needed using radio frequency link, the second modulation Demodulation module 630 may need to suspend the interaction with server.
After receiving the authentication information, the modules in mobile communication equipment are operated as follows to pass authentication information Third communication network is given, third communication network will be registered to.The control module 650 controls the second modulatedemodulate mode transfer Block 630 discharges the radio frequency link, and sends the instruction of the 4th link to selected modulation /demodulation module.Selected modulatedemodulate Mode transfer root tuber obtains the radio frequency link according to the 4th link instruction, is transmitted the authentication information using the radio frequency link Give third communication network.For example, selected modulation /demodulation module obtains the radio frequency link, the authentication information is packaged into For the data transmitted under the agreement of third communication network, and send the verifying equipment in third communication network to.The third communication Verifying equipment in network is after receiving the authentication information from selected modulation /demodulation module, by the received authentication of institute Information is compared with the authentication information that it is stored.If the two is identical, the verifying equipment confirms the third user The validity of tag card.
After the validity that third user identifier card has been determined, selected modulation /demodulation module can be described in Radio frequency link executes the data traffic transmission under the third communication network.Due to passing through the user identifier card in third communication network The data traffic transmission under third communication network is executed, so saving roaming data traffic rate.
For voice service, the data volume to be transmitted in data service is very big, and modulation /demodulation module is logical Run high-grade protocol stack often to execute data traffic transmission.As described above as can be seen that in mobile communication equipment 600 During accessing third communication network, the second modulation /demodulation module 630 is mainly used for transmitting authentication request and authentication information etc. A small amount of data, the data business volume transmitted are seldom.Therefore, the second modulation /demodulation module 630 can support inferior grade agreement Stack, for example, the protocol stack under second generation communication network can be supported only.Selected modulation /demodulation module is due to third to be executed Data traffic transmission under communication network can support high-grade protocol stack, for example, can support second generation communication network and Protocol stack under third generation communication network, or even can also support the protocol stack under forth generation communication network.In this way, can save The hardware cost of mobile communication equipment.It is selected for executing the data under third generation communication network in the first modulation /demodulation module In the case that business is transmitted, third modulation /demodulation module can also support inferior grade protocol stack.Certainly, three modulation /demodulation modules It can all support high-grade protocol stack.
