Description of the drawings

Fig. 1 is the functional block diagram of the embodiment of the present invention.

Fig. 2 is the User relationship table schematic diagram of the real-time example of the present invention.

Specific implementation mode

Present invention will be further explained below with reference to the attached drawings and examples.

The present invention is a kind of method carrying out user information correlation to each interface XDR data of core net, to each interface signaling XDR, business XDR and MR XDR carry out dynamic realtime association backfill using the method that distributed and multi-layer is handled.

The present invention is according to the correlation between each interface signaling process and business transmission process, to each interface signaling XDR(Base In the detailed record for the signaling procedure that the control plane signaling acquired generates), business XDR(Based on the user plane industry acquired Business data and the detailed record of business transmission process generated)And measurement report XDR carries out dynamic realtime association, thus will be same The corresponding each interface XDR of the same business procedure of a user is associated.And according to multiplex roles XDR association results, backfill is each The field lacked in the original XDR of interface generates complete each interface XDR.

In order to overcome influence of the big data quantity to performance, and meet the requirement handled in real time, the present invention proposes one kind The association earth-filling method of distributed and multi-layer processing, original XDR data pass through distributed receiver, sequence server, core successively The multi-level processing of the associated server of the heart generates complete each interface XDR.The present invention has flexible expansion ability simultaneously, can According to other association analysis demands of the demand flexible expansion of the development of network and business.

In order to realize that the association of big data quantity, the present invention handle data using distributed way, utilize multiple receivers(Net Metadata receives server)The original XDR that data collection layer reports is received simultaneously, each receiver only handles a part of data, To share excessive data volume.Simultaneously in order to reduce the data pressure for issuing follow-up sequence server, data are being received Reduction processing has been done at machine.Or repetition unrelated with association process is issued at each receiver the various types of messages of sequence server Caching process is done, and only transmission may build table, newer message, or query messages unduplicated as possible herein, to big It is big to reduce the data volume for being sent to follow-up sequence server.Due to there is a situation where that message sequencing is reverse, if do not adjusted The sequence that message is sent directly is associated, then can not establish correctly user information relationship immediately, it is therefore desirable to sequence service Device arranges data according to message sending time, is then sent to core associated server.Associated server respectively connects according to network The message circulation of mouth, sets corresponding correlation rule, after receiving sequence after the association messages of each interface, according to correlation rule User-association processing is carried out, data relationship table is established, contingency table is updated in time, association request number can also received According to when, find user information from User relationship table, structure backfill data-message.It is to network element data service to backfill data-message The message for the backfill data composition that device is sent.In order to ensure message circulation is minimum, by the device identification in message, to specified net Message combines after metadata receives the backfill that server is sent, and is then sent to corresponding network element and receives processing service Device.Network element data receives after server receives data, update caching, backfill message data, in this way according to being returned after association Data are backfilled, user information will have been filled out without the XDR of user information, then user information distribution service is distributed to by user IMSI Device.

Referring to Fig. 1, the embodiment of the present invention propose setting network element data receive server, sequence server, associated server, User information Distributor.When it is implemented, the number of network element data reception server, user information Distributor can root It needs to be arranged according to distribution.By taking 3 network element datas receive server, 2 user information Distributors as an example, network element 1,2,3 Each interface XDR data input network element data and receive server 1,2,3 respectively, and network element data receives the output extraction of server 1,2,3 Be associated with relevant each interface data and be all sent to sequence server, core pass is sent to after the good data of server arrangements that sort Join server, core associated server finds associated user information structure backfill data-message, connect back to corresponding network element Receive processing server;Network element receives processing server and transfers to each network element data to receive server distribution backfill result, in figure There are 2 user information Distributors, is denoted as respectively by user's Distributor 1, by user's Distributor 2, by user point Each analyzing processing server sent out server 1, continued respectively backward by user's Distributor 2(In such as figure user processing 1,2, 3…)Accordingly distributed.Embodiment provides the method for carrying out user information correlation to each interface XDR data of core net Following steps:

Step 1, each network element data receive the XDR data that server receives all kinds of interfaces from respective network elements respectively, Searching user's information in local cache relation table can directly acquire user information and be associated with if inquiring, and obtain carrying and use Enter step 5 after the XDR data of family information.It needs to arrange the data received if not inquiring.It extracts and is associated with Relevant data establish related information caching, remove repetition or are not necessarily to associated field, to final associated server need The necessary data wanted screens, and after batch is integrated, is sent to sequence server.

Step 1 realization is as follows,

When receiving some message and its associations is effective, then first searched in message in the corresponding cache table of the associations User information, if finding, so that it may which, with user information in direct backfill, association backfilling process terminates;If not finding, to receiving Data arranged after be sent to sequence server.

Embodiment is implemented as follows:

Pre-establish local cache relation table.By taking MME is the local cache relation table of user-association item as an example, the relation table It is established with Hash table structure, wherein Hash key assignments, that is, MME associations, is worth for certain user information intelligent pointer, includes the phase of IMSI Close information, such as IMEI, MSISDN.

After local cache relation table is built up, when receiving a UU message and MME values are effective, then first looked into MME cache tables The MME values in message are looked for, if finding, so that it may which, with user information in direct backfill, association backfilling process terminates;If not finding, It is sent to sequence server after being arranged to the data received, enters step two.

If it is not directly to inquire, and to disappear as table is built it is worth noting that, receiving S11 message or S1MME message Breath goes to establish or update local user's relationship cache table(If having this associations in local relation table, updates, if nothing, build It is vertical), it is sent to sequence server after then being arranged to the data received, enters step two.

Step 2, sequence server, which is received from each network element data, receives each interface data that server is sent, by data Including message send time(End time i.e. inside message)Sequence sends corresponding each interface message to association service Device ensures that the message for being sent to associated server is that the time is orderly in this way.Step 2 realization is as follows,

Orderly map tables are initially set up, the prioritisation of messages received is added in ordered list, are stored in embodiment orderly The map tables of message are denoted as dataMap_, and interval such as inspection in 0.5 second is primary at predetermined time intervals, if directly will be in dataMap_ Data are all sent, and at next 0.5 second, be inserted into dataMap_ may be the smaller data of key assignments(Key assignments is at first 0.5 Within the scope of the dataMap_ that second sends out), it is sent to data of associated server and incomplete in this way.In order to integrate to the greatest extent Data are not all to send the data in dataMap_, but after remaining portion of time relatively when patrolling each time Data, participate in subsequent sequence.

Embodiment is implemented as follows:

Orderly map tables are initially set up, the C++ data structure definitions for storing ordered message are as follows:

map<u64, list<CollectInfo_t> > dataMap_;

The major key of map is the time that message is sent(Data format is u64), the value values of map are to send the same time Messaging list, messaging list are stored in list<CollectInfo_t>In.list<CollectInfo_t>For self-defined structure, Preserve the list of same time transmission message.

The message received is added in ordered list, it is primary every inspection in 0.5 second, when patrolling each time, be not The data of dataMap_ in this 0.5 second are all sent, but remain a part of data, the foundation of retention data is as follows:

The largest key value of dataMap_ -2.5 seconds in 0.5 second(2.5 be maximum allowable Message Time Delay)=threshold value D, specifically When implementation, those skilled in the art can voluntarily preset threshold value D value.

The key assignments of dataMap_ is less than the part of threshold value D in 0.5 second, you can associated server is sent to, in 0.5 second The key assignments of dataMap_ is more than the part of threshold value D, remains in dataMap_, participates in subsequent sequence.

Step 3, associated server receive each interface message that sequence server is sent(The message passes through data receiver The processing such as the screening of server and the sequence for the server that sorts).Association refers to the data each distinct interface by signaling procedure Between correlation(That is user related information)It associates, user related information refers to that can only uniquely confirm in synchronization The information of one user, and other interface messages can be found by this information.It can be previously according to these when specific implementation User's related news carry out user-association, and establish User relationship table, whenever each interface for newly receiving sequence server and sending Contingency table is updated when message.When newly receiving each interface message, illustrate to receive association request, then from customer relationship Find user information in table, structure backfill data-message, then the message that needs backfill is combined be sent to it is corresponding Receive server.Step 3 realization is as follows,

Step A01 transfers the registration of Party membership, etc. from one unit to another according to the message flow of each interface of network, obtains the retrievable association of each interface, builds Found a kind of pattern of rational correlation inquiry;

Step A02 realizes that quick association backfills using memory grade various dimensions user message table.In order to ensure data processing Promptness takes memory grade to handle the mode periodically preserved in real time, while being directly linked to user's letter from multiple associations dimensions Breath, to improve associated speed.In order to real-time query to user information, corresponding memory is established for each associations Table directly builds table, update or inquiry according to data type after receiving data.

Embodiment is implemented as follows:

Step A01 transfers the registration of Party membership, etc. from one unit to another according to the message flow of each interface of network, establishes a kind of pattern of rational correlation inquiry.Point It analyses each interface and flows through journey in the effect of core net and message, it can be deduced that each retrievable association of interface, such as close Data are entrained by copula IMSI, MME, TMSI, MMECELL, IPv4, IPv6, TEID:

IMSI associations include IMSI(International Mobile Subscriber Identity, the world are mobile User identifier), IMEI(International Mobile Equipment Identity, International Mobile Station Equipment Identification), MSISDN(Mobile Station Integrated Services Digital Number, mobile subscriber ISDN number)Number According to item, but only IMSI is association key assignments;

MME(Mobility Management Entity, mobility management entity)Associations include MME_S1AP_ID, MME_Group_ID(MME groups identify), MME_Code(MME Code)Data item;

TMSI associations include TMSI(Temporary Mobile Subscriber Identity, interim identity)Number According to item;

MMECELL associations include MME_S1AP_ID(The unique subscriber identification of the sides MME SI interfaces), eNB_ID (Evolved Node B, evolved node B), CELL_ID(Cell ID)Data item;

IPv4 associations include the IP address of 4 bytes;

IPv6 associations include the IP address of 16 bytes;

TEID associations include TEID(Tunnel Endpoint Identifier, Tunnel End Point Identifier)Data item.

Therefore it the associations of each interface and differs, those skilled in the art can specified associations item as the case may be.

Following interfaces are all the relevant interfaces of core net

UU interfaces:IMSI associations, MME associations, TMSI associations, MMECELL associations

X2 interface:MME associations

UEMR interfaces:MMECELL associations

S1MME interfaces:IMSI associations, MME associations, TMSI associations, IPv4 associations, IPv6 associations, TEID Associations

S10/S11 interfaces:IMSI associations, IPv4 associations, IPv6 associations, TEID associations

S1U interfaces:IMSI associations, IPv4 associations, IPv6 associations, TEID associations

S6A interfaces:IMSI associations

SGS interfaces:IMSI associations

Wherein IMSI(International Mobile Equipment Identity)Refer to International Mobile Station Equipment Identification, MME(Mobility Management Entity)Refer to mobility management entity, IP(Internet Protocol)Refer to IP associations View, TEID(Tunnel Endpoint Identifier)Refer to Tunnel End Point Identifier.

It circulates with reference to each interface protocol and inter-network messages, obtaining can be made by the interface data of S1MME and S10/S11 Association, therefore user information relation table is established with S1MME and S10/S11 data, other interface data be only used for incidence relation into Row inquiry is updated user information, without establishing new user information.The incidence relation of each interface is described as follows:

According to S1MME message can associating IMSI, IPv4, IPv6, TEID, MME/TMSI, that is, pass through IP/ TEID or MME/TMSI, finds user information.

IMSI, IPv4, IPv6, TEID can be associated according to S10/S11 message, i.e., use is found by IP/TEID Family information.

Since S6A, SGS interface only have IMSI information, without IMEI, MSISDN information, but other interfaces have IMSI, The correspondence of IMEI, MSISDN, therefore by IMEI, MSISDN value of IMSI tables acquisition user, that is, find user information.

MMECELL can be associated with MME/TMSI/IMSI according to UU message, and UEMR interfaces only have MMECELL Message finds user information by UU mouthfuls of association.

When certain message contains multiple associations, suitable associations should be selected to determine user identity.According to each interface The degree that associations can uniquely determine user is different, and the preferential search order setting of associations of each interface is as follows:

UU interfaces:IMSI > TMSI > MME

X2 interface:MME

UEMR interfaces:MMECELL

S1MME interfaces:IMSI > IP > TEID

S10/S11 interfaces:IMSI > IP > TEID

S1U interfaces:IMSI > IP > TEID

S6A interfaces:IMSI

SGS interfaces:IMSI

By taking UU interface polls as an example, if there are IMSI, first from IMSI table searching user's informations, if not finding and TMSI has Effect, then continue through TMSI table searching user's informations, if not finding and MME is effective, continues through MME tables inquiry user's letter Breath.

Step A02 realizes that quick association backfills using memory grade various dimensions user message table.In order to ensure data processing Promptness takes memory grade to handle the mode periodically preserved in real time, while being directly linked to user's letter from multiple associations dimensions Breath, to improve associated speed.

After receiving data, table, update or inquiry are directly built according to data type, due to the data magnitude ratio of S1-U interface Other interfaces are much larger, therefore in addition to using mode provided by the invention, when specific implementation that can also be done to the data of the interface Individually processing, such as caching relation table is established by the IP associations of S11 interfaces, S1U interface XDR data are associated with according to IP, In backfill after user information, then by user IMSI it is distributed to user information Distributor.

In order to real-time query to user information, corresponding memory table, after receiving data, root are established for each associations Table, update or inquiry are directly built according to data type.Referring to Fig. 2, as follows:

IMSI =>User message table

TMSI =>User message table

MME =>User message table

TEID =>User message table

IPv4 =>User message table

IPv6 =>User message table

In Fig. 2, in IMSI tables, according to imsi=3, user information 1 can be found, equally, according to tmsi in TMSI tables =4, ipv4=6 can find user information 1 in Mme=5, IPv4 tables in MME tables;And it is tmsi=8 in expired TMSI tables, expired Ipv4=2 etc. are once the values in user information 1 in Mme=3, expired IPv4 tables in MME tables, but the associations being updated later, It will all be directed toward user information 1 whithin a period of time, to support those that the interface data of time value was still used to carry out user pass Connection, mode is identical the effects that user information 2.

It is fastest in order to make to build the internal memory operations such as table, inquiry, take Hash table structure to store each associations corresponding interior Table is deposited, by taking MME is the user message table that associations are established as an example:

The table is established with Hash table structure, wherein Hash key assignments, that is, associations MME_ID_t, is worth for certain user information intelligence Pointer without comprehending the release of object, therefore is used herein as intelligence since intelligent pointer can easily carry out pointer operation Pointer can discharge the user information automatically when no key is directed toward certain user information.

When certain user information is there are when multiple associations, in the table corresponding to each associations, must all there be corresponding key assignments It is directed toward same user information object.When the associations of user information change, key assignments correspondence will also occur therewith Change.For ensure user correspondence correctness, to be backfilled immediately when inquiring user information.

It is worth noting that, Hash table needs to carry out period cleaning, when there is no at least two key items in user information When, which just can not be used for doing inquiry association, so to delete the key assignments relationship and user information.There is user information The reason of lacking associations, usually because of association entry value in user information, altered directions others users.

Step 4, network element data receive the backfill message that server receives associated server, and according to backfill message, update is originally Ground caching relation table, while corresponding interface message is backfilled upper user information, gained is carried to the XDR data point of user information It is sent to each user information Distributor.

The realization that embodiment updates local cache relation table is as follows:

The backfill message received is detached first, and origination message is found from message table, further according to the user information of backfill, Update customer relationship cache table.

It is worth noting that, the IMSI tables of local cache relation table can exist for a long time, and other relation tables, because The term of validity of the associations is limited, and can not learn whether the value has been directed to other user informations, so at regular intervals It needs to remove, only retains the correspondence of a bit of time recently.

Step 5, each user information Distributor receives the XDR data for carrying user information, according in user information IMSI carries out modulus, is distributed to subsequent analyzing processing server by user, user's correlation analysis subsequent in this way can adopt Take distributed implementation.

The above content is combining, specific embodiment is made for the present invention to be further described, and it cannot be said that this hair Bright specific implementation is confined to these explanations.For those of ordinary skill in the art to which the present invention belongs, it is not taking off Under the premise of from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the protection of the present invention Range.
