Abstract
The invention relates to a method for restraining the illegal international short message service. It examines the SCCP message on STP, when the instruction point code of the message LABEL is the one of international gate office, the main calling subsystem is the short message center and the called subsystem belongs to the position register, it can intercepts the message.
Description
Technical field
The present invention relates to moving communicating field, more particularly, relate to a kind of STP of being used for (Signalling Transfer Point) and go up the method that illegal international short message service is limited.
Background technology
The short message service of mobile communication system more and more is moved the user to like that its traffic growth is cumulative year after year also owing to have economy, advantage such as convenient, fast.But this business also might be used to transmit invalid information, if this illegal short message is other operator from this country, then can manage by certain laws and regulations; But if, just be difficult to by this approach management from the illegal short message, particularly hostile nations of other country or when organizing.Desirable way is the short message that is sent by some country or some foreign operator by certain measure restriction.
With China is example, current, domestic part operator and between the external operator does not open mobile short message service, and therefore Chinese operator and external operation commercial city are by being provided with at separately SMC (short message service center), with the user that forbids oneself to end subscriber is sent SMS message; But some external operator does not take this restriction in short message service center, so its user still can send SMS message to China, and China user can only passively receive.As seen, this mode can only forbid that domestic outside state sends short message, if want to forbid being dealt into domestic illegal short message abroad, need depend on external operator whether above-mentioned restriction initiatively is set, and operator is not on hand at home for initiative.
Summary of the invention
The invention provides a kind of method that limits illegal international short message service, existing domestic operator can not initiatively forbid from external this problem of illegal short message domestic operator independently being tackled to the short message service from illegal foreign operator in the prior art to solve.
The technical solution adopted for the present invention to solve the technical problems is on STP SCCP (SCCP) connectionless information of receiving to be checked;
(1) judges earlier whether the OPC Origination Point Code in the described SCCP connectionless information label (LABEL) is the signaling point code of international gateway;
(2) if the judged result in described (1) step is for being to judge then whether the caller subsystem in the described SCCP connectionless information is short message service center again;
(3) if the judged result in described (1), (2) step is for being to judge then whether the called subsystem in the described SCCP connectionless information is attaching position register (HLR) again;
(4) if the judged result in described (1), (2), (3) step is all for being then described SCCP connectionless information to be carried out intercept process.
Why adopt such scheme, be because short message service center is when descending short-message sending, at first to send signaling to callee's attaching position register,, then can cause the short message issuing failure if send routing information failure to obtain callee's routing iinformation; Again because getting route messages is a SCCP connectionless information, so can limit illegal international short message service by interception SCCP connectionless information.
Said method is applicable to the situation when domestic operator wants to tackle all from external short message service; If only wanting to tackle from indivedual illegal external operators, domestic operator mails to domestic short message service, then in described (4) step, when the judged result in described (1), (2), (3) step all when being, also to further check the caller global title (GT) in the described SCCP connectionless information, judge whether the national code (CC) in the described caller global title is predetermined illegal national code, and judge whether the network insertion sign indicating number (NCC) in the described caller global title is predetermined illegal network insertion sign indicating number; If any is illegal in described national code and the network insertion sign indicating number, then described SCCP connectionless information is carried out intercept process.
As seen, the present invention is by judging the SCCP connectionless information from international gateway on STP, make domestic operator can active interception all from external short message service, also can optionally tackle from indivedual illegal external operators and mail to domestic short message service, autonomy is grasped at home in operator's hand, compare with the mode that can only lean on external operator initiatively to be provided with in the prior art, its advantage is conspicuous.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the flow chart that short message service center issues short message signaling in the mobile communication system;
Fig. 2 is the flow chart of the inventive method one;
Fig. 3 is the flow chart of the inventive method two.
Embodiment
Method one, tackle all from external short message service
As shown in Figure 1, when under the short message service center during short-message sending, at first to send MAP_SEND_ROUTING_INFO_FOR_SM (getting route requests) signaling, to obtain callee's routing iinformation to callee's attaching position register.The failure if send routing information then can cause the short message issuing failure.Therefore in order to limit illegal international short message service, reduce useless signaling message, can tackle the route signaling message of getting that Gateway Short Message Center issues, this message is abandoned, short message just can't correctly be handed down to the callee like this.
This technology is to realize at the SCCP of No.7 signalling system layer.Concerning SCCP, therefore only the route messages of getting that issues from short message service center is the SCCP connectionless information that a calling and called subsystem is respectively SMC (0x08) and HLR (0x06), need tackle the SCCP connectionless information that the calling and called subsystem that transmits from international gateway is respectively 0x08 and 0x06 and get final product on STP.Why adopt this mode to be based on following basis: between the signalling interworking of carrier network and external carrier network, not exist external short message service center directly to visit the situation of domestic HLR at home; Have only domestic SMC can inquire about domestic HLR, do not allow the international domestic HLR of SMC visit.
As shown in Figure 2, in this method, on STP, the SCCP connectionless information of receiving is judged, if the OPC Origination Point Code among this message LABEL is that the signaling point code of international gateway, the caller subsystem in the while message are that 0x08, called subsystem are 0x06, represent that then this is one and gets route messages by external provider customer by what domestic short message service center issued, therefore need carry out intercept process to this SCCP connectionless information, for example this message be abandoned or error messages of loopback.As seen, tackle, needing to satisfy from international gateway, caller subsystem simultaneously is that SMC, called subsystem are these three conditions of HLR; If do not satisfy wherein arbitrary condition, then receive and handle described SCCP connectionless information by normal flow, needn't carry out intercept process to it.
Utilize signaling point code among the SCCP connectionless information LABEL to determine the source of message among the present invention, mainly contain following reason:
1, all will carry out the SCCPGT translation at international gateway from mailing to domestic Signaling System Number 7 message abroad at present, and all are the HSTP (HSTP High Signaling Transport Point) that translation extremely links to each other with international gateway, are translated downwards by STP again; Owing to do not have the message transparent transmission, all will therefore can judge that whether the message of receiving is from international gateway through SCCP GT translation by the signaling point code among the SCCP connectionless information LABEL;
If 2 do not adopt the signaling point code among the LABEL, but adopt the GT sign indicating number in the SCCP connectionless information calling and called address to judge informed source, then need to judge the GT sign indicating number part of all SCCP connectionless informations; Consider that STP also carries the transmission of domestic inter-provincial Signaling System Number 7 message, this judgement will exert an influence to domestic inter-provincial Signaling System Number 7 message by STP, SCCP GT sign indicating number in the domestic Signaling System Number 7 message might be with national code simultaneously, therefore need also in processing to consider whether GT is international number, increased the complexity of handling.
The employing method for the moment, the SCCP connectionless information that might to tackle other calling and called subsystems from international gateway be 0x08 and 0x06.At present qualified have two kinds, a kind of is to get route signaling information MAP_SEND_ROUTING_INFO (getting the route signaling information), consider that the calling between present net all carries out intercommunication from gateway exchange between net, therefore can this message from the message that international gateway is come; Another kind may be USSD (non-structured supplementary service data) message, considers the USSD business of now also not carrying out between net, does not therefore also have this message between net; So interception can not make the mistake.
Method two, interception are mail to domestic short message service from indivedual illegal external operators
Be the short message service center of external illegal operator number because short message service center sends the SCCP calling address got in the route messages to called subscriber's attaching position register, therefore can utilize the short message service center of external illegal operator number to tackle external illegal provider customer and mail to domestic short message.
In mobile communication system, MSISDN (travelling carriage ISDN number) is meant that the calling subscriber dials the number that cries for calling out the mobile subscriber, adopts E.164 coding, it consists of CC-NDC-SN, wherein: CC (Country Code) is a national code, i.e. the national code of travelling carriage registration is 86 as China; NDC (National DestinationCode) is domestic object code, i.e. network insertion number has 139,138,137,136,135 at present as the NDC of China Telecom; SN (Subscriber Number) is a mobile subscriber number.
As shown in Figure 3, this method is on the basis of method one, further analyzes the caller GT sign indicating number of SCCP connectionless information, if having one in the national code of caller GT sign indicating number or the network insertion sign indicating number for illegal, then this SCCP connectionless information is carried out intercept process.
As seen, in this method, have only at the same time that to satisfy from international gateway, caller subsystem be that SMC, called subsystem are these three conditions of HLR, and have one in national code or the network insertion sign indicating number when illegal, just can carry out intercept process; If have any not satisfy in first three condition or national code and network insertion sign indicating number all are legal, then receive and handle described SCCP connectionless information by normal flow, all needn't carry out intercept process.
