Description of drawings
Fig. 1 is that a kind of different user based on signaling of the present invention is at the flow chart of the recognition methods of the signing identical ip addresses of HLR.
Embodiment
The present invention is described in further detail below in conjunction with Figure of description and embodiment.
Fig. 1 shows a kind of different user based on signaling of the present invention at the flow chart of the recognition methods of the signing identical ip addresses of HLR, and as can be seen from Figure, the method mainly comprises the following steps:
Step S11: related signaling collection;
Gather the original signaling of GPRS network Gb Interface and TD network IuPS interface; Described original signaling comprises the PDP activation process signaling of Gb Interface and IuPS interface.Method of the present invention need to gather the original signaling of Gb/IuPS interface of GPRS/TD network, should be noted that collection can not interrupt the existing network business, can not increase the load of existing network equipment, guarantees the Cybersecurity Operation state.Acquisition mode can be selected CE mirror image, TAP shunting, three kinds of modes of optical splitter light splitting, and acquisition mode is prior art.Gb Interface is the interface between the wireless and core net of 2G GPRS network; The IuPS interface is the interface between 3G TD network wireless and core net, and method of the present invention can be analyzed the problem of 2G, 3G network simultaneously.What need in this step to gather is the PDP activation process related signaling of Gb Interface and IuPS interface, specifically comprise PDP activation request and PDP activate accept, PDP activates refuse information.
Step S12: signaling is resolved;
The original signaling that collects in step S11 is resolved, obtain HLR contracted user's TLLI sign, the pdp address information of user's application and user's IMSI sign; Described parsing comprises that PDP activation request message parse, access point APN information and PDP are activated refuse information to resolve.
In the mobile network, the industry user can use specific user signing contract information when surfing the Net or using specific vpn service, these CAMEL-Subscription-Information mainly comprise: the industry APN of appointment, the static ip address of appointment, these information can carry out reporting when PDP activates the user, so that the user can use particular ip address to surf the Net, use specific vpn service.When the signing IP address of HLR was identical, if two users surf the Net simultaneously, a user had activated successfully as two industry users, and another user's PDP activation request will be refused by GGSN.Therefore can automatically identify this problem by the PDP activation process of parsing and analysis user.The concrete mode of in this step, signaling being resolved is as follows:
(1) PDP activation request message parse
The signaling (PDP request) that Gb/IuPS interface message SM layer type of message is 0x41 is resolved, obtain user's TLLI sign (intercepting the 2nd to-5 byte of this message BSSGP sublayer), the pdp address information of user's application (intercept the Requested PDP address information of this message SM sublayer, these addresses mainly comprise PDP type number-IP address version-v4 or v6, static state or dynamic address, static address information), APN information (intercepting the Access Point Name of this message SM sublayer).
(2) PDP activates the refuse information parsing
Be that 0x43 and Cause Code value are that 28 signaling (PDP refusal-unknown pdp address or PDP type) is resolved to Gb/IuPS interface message SM layer type of message, the IMSI sign (intercepting 88 two bytes of BSSGP layer 0d 1-8 byte backward of this message) and the TLLI that obtain the user identify (intercepting the 2nd to-5 byte of this message BSSGP sublayer)
Step S13: judge the user who has the conflict of HLR subscription data.
Judge the user who has the conflict of HLR subscription data according to the signaling analysis result.According to resolving the information of obtaining in step S12, determine the user who has the conflict of HLR subscription data.When user's HLR subscription data satisfies following three conditions, be judged as due to the conflict of HLR subscription data, thereby caused the user can't normally use business:
(1) static address of applying in the PDP activation request of user A, and the APN of application access is industry APN;
When definite user applies for whether the APN business that accesses is industry APN business, can judge in conjunction with the APN list of operator whether the APN of user's application is industry APN.
(2) this user's PDP activation request sometimes can be successful, and is sometimes unsuccessful, and when failure the error reason that returns of network side be ' unknown pdp address or PDP type ';
Report in user's PDP activation request in the situation of identical industry APN, pdp address type, static PDP address in this step, sometimes can activate successfully, sometimes can be failed.
(3) in network, other users (user B) also use identical static ip address application to activate, and once activate successfully, and when user A activated unsuccessfully, user B was in state of activation just.
The identical user of information who reports by record all information that report (APN, pdp address type, static PDP address) and user A in the PDP activation request, when user A activate unsuccessfully and failure cause when ' unknown pdp address or PDP type ', have the user to use identical information to activate successfully.
Satisfy can being judged as due to the conflict of HLR subscription data of these three conditions, thereby caused user A sometimes can't normally use business, after completing judgement, there is the route area list of redundant configuration in statistics, relevant HLR information to this user is added up, comprise this user's IMSI, the APN of application, IP address, the IP address class type of application and the number of users that has information collision that application activates, as shown in the table:
User IMSI: user ID, corresponding with subscriber phone number, but user of unique identification
The industry APN that in the APN:PDP activation request of application, application activates
The IP address of application: the industry user applies for the static ip address that activates
The address style of application: the address style (IPv4 or IPv6) of application when the user activates
CAMEL-Subscription-Information conflict number of users: have what users to use identical signing IP address successfully to activate in network.
According to statistics, if different IMSI applied for identical APN and application is identical static address, think that there is conflict in the HLR subscription data.
The judgement of pdp address conflict when method of the present invention has realized that industry user HLR is signing, cross the mobile data network signalling analysis, industry user to the usage data business carries out trace analysis, by the PDP activation of user's online is resolved and association analysis, automatically find and recognition network in two contracted users apply for simultaneously the situation of 1 IP address, troubleshooting and the optimization of guidance to industry user's indulging in the internet.
Obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of claim of the present invention and equivalent technology thereof, the present invention also is intended to comprise these changes and modification interior.
