A kind of method that the embodiment of the present invention provides the MTC of protection equipment not attacked by false triggers short message, comprising:
1A:SMS-SC receives transmission request, and SMS-SC generates short message according to described transmission request.
SMS-SC is in the described short message generating, by the type of this short message of indication.The type of described short message may be " the triggering class note that comes from trusted servers ", may be also " incredible triggering class note ", may be also other types.
1B, SMS-SC are used normal SMS flow process to send described short message.
1C, MTC equipment, after receiving described short message, will detect the type of described short message.
1D, MTC equipment, after receiving described short message, also trigger relevant detailed information by whether having in the user data of the described short message of detection.
If the type of the described short message that 1E MTC equipment receives is " the triggering class note that comes from trusted servers ", and in the user data of short message, there is the detailed information that described triggering is relevant, the further operation that MTC equipment triggers according to the user data relevant information of described short message; If the type of the described short message that MTC equipment receives is " incredible triggering class note ", no matter in the user data of short message, have or not the detailed information that described triggering is relevant, the further operation that MTC equipment can not trigger, now MTC equipment arranges and carries out other operations according to user, as short message as described in abandoning.
Wherein, if the transmission request that SMS-SC receives is Submit Trigger (submit to and the trigger) message that comes from T4 interface, and it is to trigger target device that the SMS Application port ID comprising in described Submit Trigger message (short message application port sign) parameter is indicated the function of this short message, and SMS-SC is " the triggering class note that comes from trusted servers " by the Sort positioning of described short message.
Wherein, if the transmission request that SMS-SC receives is to come from SMS-IWMSC, and in SMTP SMS-SUBMIT (submission of short message transmission layer protocol short message) message, indicating this message is to trigger class short message, and SMS-SC is " incredible triggering class note " by the Sort positioning of described short message.
Wherein, if the transmission request that SMS-SC receives is to come from Tsms interface, SMS-SC locates the type of described short message according to other strategies.
Wherein, if the transmission request that SMS-SC receives is the Submit Trigger message that comes from T4 interface, and it is to trigger target device that the SMS Application port ID parameter comprising in described Submit Trigger message is indicated the function of this short message, by parameter S M TP-PID () in SM TP SMS-DELIVER (transmissions of short message transmission layer protocol short message) message is set, to indicate the type of described short message be " the triggering class note that comes from trusted servers " to SMS-SC.
Wherein, if the transmission request that SMS-SC receives is to come from SMS-IWMSC, and it is to trigger class short message that the parameter S M TP-PID (short message transmission layer protocol-protocol-identifier) in SM TP SMS-SUBMIT message indicates this message, by parameter S M TP-PID in SM TP SMS-DELIVER message is set, to indicate the type of described short message be " incredible triggering class note " to SMS-SC.
Wherein, MTC equipment is after receiving described short message, by checking that parameter S M TP-PID in SM TP SMS-DELIVER message determines the type of described short message.
Fig. 1 has described the path of the short message that UE may receive.As described in Figure 1, the short message that UE receives may come from following San Ge path:
The short message that one: UE receives comes from other UE.Source UE is by MO (Mobile Originate, terminal initiation) mode is sent to SMS-SC by short message through SMS-IWMSC, the mode that SMS-SC passes through MT (Mobile Terminated, terminal receives) is again sent to object UE by described short message.
Its two: the short message that UE receives comes from SCS (Service Capability Server, service capability server).The short message that under this paths, UE receives is for triggering class short message.SCS sends a device trigger request (device trigger request) message by Tsp interface to MTC-IWF; After MTC-IWF authenticates SCS, then to SMS-SC, send a Submit Trigger message by T4 interface; SMS-SC triggers class short message according to one of some parameter generating in described Submit Trigger message, and the mode by MT is sent to object UE.
Its three: the short message that UE receives comes from SME (Short Message Entity, Short Message Entity).SME is the entity outside 3GPP standard, and SMS-SC will authenticate SME, guarantees to come from the fail safe of SME message.SMS-SC receives after the short message coming from Tsms interface, and the mode by MT sends to object UE by this short message.
If object UE is MTC equipment, the triggering class short message that MTC equipment receives so may come from T4 interface, comes from the triggering class short message of SCS; The triggering class short message that MTC equipment receives also may come from SMS-IWMSC, comes from the false triggers class short message of other UE.
Fig. 2 has described relevant SM MO/MT application layer and the transport layer protocol of SMS-SC, and how SMS-SC describes the type of SM in described agreement;
Wherein:
SMI is Short Message Identifier;
DA is destination address, has indicated the sign of object UE;
OA is source address, has indicated the sign of source UE;
PID is protocol-identifier, has indicated type and the decoding agreement of short message;
SM is content of short message;
SCA is SMS_SC address;
All the other parameters are with reference to 3GPP TS23.040.
If source UE will send a short message to object UE, first source UE will initiate SMS MO process to SMS-SC; Then SMS-SC produces a MT short message according to the MO short message receiving, and by SMS MT course, described short message is sent to object UE.
Can be by the parameter PID indication short message types in the short message of its transmission at this process Zhong， source UE, short message types can be picture category short message, mail class short message, word class short message etc.; If object UE is MTC equipment, source UE also may be appointed as short message types " triggering class short message " by change PID, by SMS-SC, short message is sent to target MTC equipment, thereby make MTC equipment be subjected to false triggers class short message, attacks.
In the embodiment of the present invention, it is " trigger class short message " that PID no longer only indicates short message types, and short message types is divided into " the triggering class note that comes from trusted servers " and " insincere triggering class short message ".SMS-SC, when producing MT short message, indicates the type of short message by the TP-PID parameter of SM to object UE.Object UE receives after short message, according to the type of the TP-PID parameter judgement short message of described short message, and further operates according to certain way.
Fig. 3 has described SCS in the present invention and by T4 interface, has triggered the flow process of target MTC equipment.
Step 301-302, SCS wants to trigger a MTC equipment, and SCS is to MTC-IWF transmitting apparatus triggering request, and MTC-IWF receives after the device trigger request message that comes from SCS, SCS is authenticated, guarantee that SCS authorizes the legal server that can trigger described MTC equipment.The method that the content of device trigger request message and MTC-IWF authenticate SCS is with reference to 3GPPTS23.682.
Step 303, if MTC-IWF determines to use T4 mode to trigger described MTC equipment, MTC-IWF sends a Submit Trigger message to SMS-SC, message comprises outside sign or MSISDN (the Mobile Subscriber International ISDN/PSTN number of target MTC equipment, mobile subscriber International ISDN/PSTN code), the IMSI of target MTC equipment (International Mobile Subscriber Identification Number, international mobile subscriber identity), SCS sign, Trigger reference code, short message effective period, priority, SMS application port ID and other message.Wherein SMS application port ID serves SMS-SC, for indicate the function of described short message for triggering class function to target MTC equipment.The particular content of Submit Trigger message is with reference to 3GPPTS23.682.
SMS-SC, after receiving described Submit Trigger message, returns to a Submit Trigger Confirm (submit to trigger confirm) message to MTC-IWF, informs described in MTC-IWF that short message is accepted by SMS-SC.The particular content of Submit Trigger Confirm message is with reference to 3GPPTS23.682.
Step 304, MTC-IWF sends a Device Trigger Confirm (device trigger confirmation) message to SCS, informs that SCS network accepted its device trigger request.Device Trigger Confirm message reference 3GPP TS23.682.
Step 305, SMS-SC produces a SMS according to the content in Submit Trigger message.If short message transmission request is the Submit Trigger message that comes from T4 interface, and it is to trigger described MTC equipment that the SMS application port ID in Submit Trigger message indicates the function of this short message, SMS-SC arranges parameter S M TP-PID in SM TP SMS-DELIVER message to indicate the type of described short message is " the triggering class note that comes from trusted servers ".
Step 306-308, SMS-SC is sent to UE by described short message.Concrete agreement is with reference to 3GPPTS23.682 and 3GPP TS23.040.
Step 309, SMS-SC sends a short message transmission and reports to MTC-IWF, informs described in MTC-IWF whether short message is successfully received by object UE.Concrete message content is with reference to 3GPPTS23.682.
Step 310, object UE is after receiving described short message, by checking that parameter S M TP-PID in SM TP SMS-DELIVER message determines the type of described short message.If described short message types is " the triggering class note that comes from trusted servers ", and in the user data of short message, there is the detailed information that described triggering is relevant, the further operation that MTC equipment triggers according to the relevant information in described short-message user data, and SCS connects; If the type of the described short message that MTC equipment receives is " incredible triggering class note ", no matter in the user data of short message, have or not the detailed information that described triggering is relevant, the further operation that MTC equipment can not trigger, now MTC equipment arranges and carries out other operations according to user, as short message as described in abandoning.
Fig. 4 has described the flow process that false triggers class short message that how the present invention program to protect object UE not to be subject to coming from source UE is attacked.
Step 401-404, source UE is sent to SMS-SC by short message by SMS-IWMSC according to normal SM MO process, SMS-SC is after normally receiving the short message that comes from source UE, by SMS-IWMSC, to former UE, return to a transmission report, inform described in the UE of source whether SMS-SC has normally received described short message.Detail is with reference to 3GPP TS23.040.
Step 405, SMS-SC receives a short message, if described short message is to come from SMS-IWMSC, and it is to trigger class short message that the parameter S M TP-PID in SM TP SMS-SUBMIT message indicates this message, by parameter S M TP-PID in SM TP SMS-DELIVER message is set, to indicate the type of described short message be " incredible triggering class note " to SMS-SC.If described short message is to come from SMS-IWMSC, and it is the short message (as types such as word, image, mails) of other types that the parameter S M TP-PID in SM TP SMS-SUBMIT message indicates this message, SMS-SC does not modify to the parameter S M TP-PID in SM TP SMS-DELIVER message when generating MT short message.
Described SM TP SMS-SUBMIT and described SM TP SMS-DELIVER refer to the classification of transport layer short message, by SM TP-MTI (SM TP-Message Type Indicator, the indication of short message transport protocol-information type) parameter indication.SM TP SMS-SUBMIT message represents that the message of this transport layer is by UE, to be transferred to the short message of SMS-SC; SM TP SMS-DELIVER message represents that the message of this transport layer is by SMS-SC, to be transferred to the short message of UE.Concrete detailed rules and regulations are with reference to 3GPPTS23.040.
Step 406-409, SMS-SC is sent to object UE by short message by SMS-GMSC according to normal SM MT course.Object UE, after normally receiving the short message that comes from SMS-SC, is returned to a transmission report by SMS-GMSC to SMS-SC, informs described in SMS-SC whether object UE has normally received described short message.Detail is with reference to 3GPP TS23.040.
Step 410, object UE is after receiving described short message, by checking that parameter S M TP-PID in SM TP SMS-DELIVER message determines the type of described short message, to judge that the type of this short message is " the triggering class note that comes from trusted servers ", still " incredible triggering class note ", or or other types.
If the type of the described short message that object UE receives is " the triggering class note that comes from trusted servers ", and in the user data of short message, there is the detailed information that described triggering is relevant, the further operation that object UE triggers according to the user data relevant information of described short message; If the type of the described short message that object UE receives is " incredible triggering class note ", no matter in the user data of short message, have or not the detailed information that described triggering is relevant, the further operation that object UE can not trigger, now object UE arranges and carries out other operations according to user, as short message as described in abandoning.If the type of the described short message that object UE receives is other types, according to the decoding process of other types, user data is processed.
