Description
A kind of method that the present invention relates in mobile communication system, connect, comprise at least one subscriber board and a network infrastructure in this mobile communication system, comprise one first counter and first value that calculates by this counter in the subscriber board, comprise one second counter and a register in the network infrastructure, including by this second counter in the register is second value that subscriber board calculates; This method comprises the following step: send a setup requests from described subscriber board to network infrastructure on a calling channel, wherein have first value; First value that is included in the described setup requests is played response, and retrieval is about second value of described subscriber board from register; Described first value that is included in the setup requests is compared with described second value that retrieves from register; If described comparative result shows that both are identical for first value and second value, then accept described setup requests.
The present invention is specifically related to, and for the unencrypted subscriber board identification information that the application simulation technology sends on the radio route in mobile communication system, can prevent that it from being abused by the people; Yet, in utilizing the wireless system for transmitting data of other technology, when unencrypted subscriber board identification information and/or unencrypted user totem information must send in radio route, and its identification information have by the people abuse dangerous the time, also can use the present invention.
When radio net is not supported to encrypt, in the time of perhaps must sending unencrypted identification information by radio route owing to certain other reason, a kind of danger will take place, and the someone can copy this identification information by radio route, uses it and obtains the subscriber board duplicator.This type of duplicator can be used to spend the bill of basis subscriber board, and system does not detect the existence of this duplicator.Subscriber board is considered to mean the actual device and the integral body of information here, and the characteristic that may add by means of wherein for example smart card, SIM (subscriber identification module) card in all gsm systems in this way of smart card.
Narrated a kind of system among the EP163358, sent a test value relevant from subscriber board to network infrastructure there with call setup.If the test value that finds in network infrastructure is identical with the test value that subscriber board sends, then accept this call setup, use identical formula by subscriber board counter and network infrastructure counter and from this test value, calculate a new test value, new test value and next call foundation are combined application.But the problem of this solution is, always change in the same way for checking employed number, and anything but at random.
In order to prevent to be abused, developed the subscriber board that a kind of checking system is used for simulating NMT (NMT) network as an example by the non-encrypted information that radio route sends.This checking system requirement, on subscriber board, must add one independently circuit in order to implement confidentiality algorithm, and requiring to be applied to the random number of a set-point of conduct that produces by switch, it must calculate same complicated algorithm between detection period in subscriber board and switch.If the result who provides and transfer to switch by algorithm by subscriber board with go out by switch computes both are identical as a result, then subscriber board will be by this check.This random number and from subscriber board both send as signaling independently as a result.Here, caused about check complexity and the problem that needs additional signaling.In addition, this solution does not inform that in arbitrary mode the operator has the attempt of any abuse subscriber station information.In utilizing the network of digital technology, used the result that a kind of similar method is implemented complicated algorithm and relatively obtained.
The objective of the invention is with simple, detect existing of subscriber board duplicator without the mode of additional signaling, and prevent the use of duplicator when needed.The method that reaches this purpose among the present invention is characterized in that, in network infrastructure, maintain and select a random number, respond and select this random number accepting call setup, on a service communication channel, send described number to described subscriber board, upgrade first value with the described number in the described subscriber board, upgrade second value with the described number in second counter, with described second value in the second value replacement register that upgrades.
Here, setup requests is considered to mean the certain methods step, and their enforcement is to connect mutually with the call setup that is derived from subscriber board, until the network infrastructure route that can continue clearly, also promptly knows called whole B number.The B number is the telephone number of user B.User B is a called side, and user A is a side of caller.If desired, can comprise the subscriber board network registration in the setup requests.
Here, upgrade the old value of value replacement that is considered to mean with new, and new value depends on old value and the number of selecting at random.
The invention still further relates to a kind of mobile communication system switch of the method that can use the present invention therein.Switch of the present invention is characterized in that, it also includes is responsible for the relatively choice device of measure, be used to select a random number so that upgrade first value and second value, arrange a linkage unit to be used on the service communication channel, sending this number again to subscriber board, arrange counter to upgrade second value, arrange controller that second value of described renewal is stored in the register with described number.
The invention still further relates to a kind of mobile communication system user platform of the method that can use the present invention therein.Subscriber board of the present invention is characterized in that, arrange a transceiver on the service communication channel, to receive the number that mobile communication system is come, this number is applied to upgrade first value, also comprise the calculation element that upgrades the first value usefulness with described number in the counter, its feature also is to arrange described controller to control described storage device, is worth as described first value in order to first of storage update.
The invention still further relates to a kind of mobile communication system of method, switch and the subscriber board that can use the present invention therein.Being characterised in that of this mobile communication system: it is arranged to random number of selection to set up request in response to call accepted; Switch is arranged on the service communication channel sends this number to subscriber board; Subscriber board is arranged to described number renewal first value; Second counter is arranged to described number renewal second value.
The thought of institute of the present invention foundation is to use a Counter Value that changes randomly, and the call setup that is used to get in touch from subscriber board is discerned subscriber board.Therefore, the most significant advantage of the present invention is that the identification of subscriber board is simple, convenient and reliable to the identification of duplicator use, for detecting at the latest that duplicator uses, be after duplicator uses, to send one when calling out by the basis subscriber board, and when this information only may be used on next call in the application in short-term of the information of eavesdropping.In addition, an advantage of the present invention is that it makes the eavesdropping difficulty, because the Counter Value that is verified sends out from subscriber board, makes the random number of counter-increments send to subscriber board simultaneously in the service communication channel in calling channel.Use different channels to make eavesdropping complicated significantly, needing the complicated equipment with the height cost tries to achieve and eavesdrops successfully, therefore the possible economic gain that is obtained by duplicator can not compensate the cost in eavesdropping, especially wish public telecommunication network is set up one when connecting when the basis subscriber board, duplicator will be detected the most at that time.
In a preferred embodiment of the present invention, subscriber board will be informed the activation of network infrastructure about counter, and the public telecommunication network of each calling make to to(for) this subscriber board can make counter work after this.The characteristic that this kind given by each other activation will be introduced in mobile communication system gradually.It can also both make in a mobile communication system does not have the old subscriber board of counter to use, and the new subscriber board that includes counter side by side can be used, and can not cause system's operation to be gone up confusion takes place.In addition, counter is easy to operation, can and add in the subscriber board in conjunction with the subscriber board maintenance.
In a preferred embodiment of the present invention, before subscriber board confirms that the subscriber board counter upgrades, the Counter Value of network infrastructure one side can not upgrade, and, if do not receive this affirmation, Counter Value will be updated to such value, promptly be received in next call and will set up included subscriber board Counter Value in the request, no matter and it is updating value or preceding value.Can make the chaotic effect in the operation accomplish minimum like this, being reduced to only is to connect the release of setting up.
The preferred embodiment of this method, switch and subscriber board is published in the appended relevant claim.
Below, by means of the preferred embodiments of the present invention also with reference to the accompanying drawings, the present invention will be described in more detail.In the accompanying drawing,

Fig. 5 illustrates the block diagram of the present invention's mobile communication system.
Fig. 1 and Fig. 2 show the method for understanding first preferred embodiment among the present invention, here suppose with example, the mobile communication system of utilizing wireless data transmission is the special-purpose land mobile radio system of a relaying, it also provides the connection to all duty PSTN of fixed network (public switch telephone network), and after this calling of sending to PSTN is called the PSTN calling.Here suppose with example again, equipment and system are all based on simulation PMR (PMR private mobile radio) system standard of stipulating in two publications, two publications are: be published in January, 1988, revise and reprint in the MPT of Radiocommunication Bureau 1327 in November, 1991, the signaling standard that the special-purpose land mobile radio system of relaying is used; Be published in January, 1988, revise and reprint in the MPT1343 of Radiocommunication Bureau in September, 1991, performance specification.They are published by the Britain's trade and the Ministry of Industry.Here supposition, subscriber equipment is the radio unit (RU) according to this standard, switch is a relay system controller (TSC), a database also is that register is included in the node, include essential information in the register, and registered all subscriber boards therein about this subscriber board.All users are stipulated by means of register information.Here with the example supposition, including by one second counter in the register is one second value that the user calculates.Each second value also can be arranged in other place of network, for example in the distinctive register that they control oneself of user.Here again with the example supposition,, can be to allow for calling out in the network of making by duplicator, they do not compare between Counter Value.The PSTN that just will keep accounts calls out " controlled " just respectively, just Counter Value is compared together with this type of calling.More also can in predetermined type of call, realize between the counter with certain alternate manner, or correspondingly between counter, do not implement relatively for specific type of call.Counter also can be used in conjunction with user registration, but at that time more situation can take place, and also promptly can integrally produce signaling on a frequency in calling channel, thus, and Counter Value tracked more or less freely.
It also is that radio unit RU wants to make the flow chart that moves when PSTN calls out the user that Fig. 1 illustrates subscriber board.Counter activates, and is applied to subscriber board.On the step 10, subscriber board is called out with normal mode request PSTN in calling channel, and on step 11, in calling channel, receive a long code request from network infrastructure, because according to standard, called pstn telephone number also is a B number and not exclusively be suitable for call request message in the present example, subscriber board sends it individually in a long code message.After the subscriber board counter activated, on step 12, subscriber board automatically joined a Counter Value on the message of long code.On the step 13 after this, subscriber board sends out long code message in calling channel.Therefore, be sent out according to a setup requests of MPT1327 standard, its signaling symbols standard, yet this long code message that includes information related to the present invention is not included in this standard.Next step, on step 14, subscriber board receives the security code request message in the service communication channel, preferably comprises the number of a picked at random in this message, is used for the refresh counter value.This number can be used as one independently message send out, but in this occasion, need a new information and additional signaling.Request plays response to security code, and subscriber board sends out security code to network infrastructure on step 16.On step 17 with this number refresh counter value, and on step 18 storage this updating value.On step 19, call setup continues with normal mode then.Counter Value in step 17 renewal and the storage in the step 18, can before sending the step 16 of security code, carry out, or carry out concurrently with it.
In the step 17, the number that adding receives above it that is applied in that Counter Value preferably stands modular arithmetic upgrades, and Counter Value remains within null value and the selected boundary, and its numerical value always is suitable for long code message; Yet this value depends on old value and receiving number.The listener-in, the personnel that also promptly made duplicator, he must know the modulus that calculates by mould (just, its value of arbitrary number that is lower than it exists all the time), Counter Value and the number that receives.Here, also can use other update methods.
Among Fig. 2, on the step 30, in calling channel, receive call request message from subscriber board by network infrastructure.Want PSTN to call out owing on step 31, detect subscriber board,, also promptly send the whole B number that in calling channel, to call out so on step 32, require subscriber board to send long code according to message content.On the step 33, long code message is played response; On the step 34, the information of register R is made check, judge whether sharp the request of subscriber board counter connects.If un-activation then continues call setup with normal mode on step 46.All subscriber boards all comprise under the situation of a counter in network, do not need to check the activation of each counter.
If the subscriber board counter is activated, then on step 35, separate first Counter Value and B number.Then, on the step 36 by register R retrieval user platform second Counter Value.In the step 37, two values are compared.If show on the step 38 that two numerical value are identical, then on step 39, accept this setup requests, transmission is carried out in the service communication channel.On the step 40, select the number of a preference in the number collection of network infrastructure storage randomly, on step 41, this number is added in the security code request message.Number also can be selected by other reason, for example, often takes number subsequently in the number collection.On the other hand, can not need the number storing collection, because the number energy collecting is as the result of the computational algorithm of implementing in the network infrastructure and obtain.Computational algorithm also can only produce a number, thereby does not need the number collection.Number can obtain from a random number generator again.On the step 42, the security code request message is sent to subscriber board in the service communication channel.Therefore, first Counter Value and the number that is used for its renewal are in different channel by radio route.Subscriber board confirms that by means of sending security code this number receives and is applied to upgrade.Meanwhile, it also confirms the renewal of first Counter Value.On the step 43, obtained security code if be judged as, then on step 44, use with subscriber board in the identical update method that adopted, second counter in the network infrastructure is upgraded its second Counter Value.On the step 45, second value of upgrading is stored as the second new value.So first value of subscriber board will be identical with second value among the register R.Then, in step 46, continue call setup in normal mode.
On the step 43, do not receive security code from subscriber board, can not know then whether subscriber board has received and comprise the message of upgrading number, can not know therefore whether first value upgraded if be judged as.For this reason, on the step 47, preferably store a numeric character, be used for the subscriber board counter in the register as second value.On the step 48, cancellation is to the acceptance of setup requests.Numeric character can be guaranteed, will be accepted in conjunction with next PSTN calling by subscriber board first Counter Value that send, that can be arbitrary value.Next PSTN call request is played response, and the numerical value that second value among the register R obtains in being upgraded by first Counter Value replaces, and this first Counter Value is received from subscriber board, has the number of selecting randomly.
The solution that a kind of safety and reliability is arranged, it than before method need take more memory span, and need make more complicated comparison, second value that it will upgrade is stored among the register R that includes second value as the 3rd value, calling out first Counter Value that will be received from subscriber board and second value and the 3rd value in conjunction with next PSTN compares, only when first value was identical with second value or the 3rd value, request was set up in square call accepted.Next PSTN that has accepted has been called out response, be used for replacing second value and the 3rd value with upgrading the value that obtains in first Counter Value, this first Counter Value is received from subscriber board, have the number of selecting randomly.
In the judgement of step 38,, then on step 49, send out one about there being the message of duplicator to the operator if first Counter Value is different mutually with second Counter Value.On the step 50 after this, program continues according to operator's decision.According to the content of message, determine it communication objectivelyly and transmission means by the operator.This message for example can be an alarm.The operator can determine the renewal with second Counter Value proceeded of call setup again.First Counter Value does not upgrade.About the calling of wanting, the operator some options have been provided: continue this call setup in normal mode and cancel acceptance to setup requests; Subscriber board is masked as the acceptance of being cancelled by free call on sb. else's expense through illegal means setup requests; Restriction PSTN authority is for example only allowed local call and is cancelled request to call setup.Renewal about second value in the register has provided some options to the operator: do not upgrade second value; Upgrade numeric character as second value; To be received from first Counter Value storage of subscriber board as second value; To be received from first Counter Value storage of subscriber board as the 3rd value among the register R.
If counter is activated, do not comprise a Counter Value but include in the message of B number, then program is identical with the situation that second value departs from mutually with first value.
