Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
The present invention is a kind of method of core net each interface XDR data being carried out to user information correlation, uses the method for distributed and multi-layer process to carry out dynamic realtime association backfill to each interface signaling XDR, business XDR and MR XDR.
The present invention is according to the correlation between each interface signaling process and business transmitting procedure, detailed record to the signaling procedure that each interface signaling XDR(generates based on gathered chain of command signaling), the detailed record of business transmitting procedure that generates based on gathered user face business datum of business XDR() and measurement report XDR carry out dynamic realtime association, thus each interface XDR corresponding for the same business procedure of same user to be associated.And according to multiplex roles XDR association results, backfill the field lacked in the original XDR of each interface, generate complete each interface XDR.
In order to overcome the impact of big data quantity on performance, and meet the requirement of process in real time, the present invention proposes a kind of association earth-filling method of distributed and multi-layer process, original XDR data through the multi-level process of the associated server of distributed receiver, sequence server, core, generate complete each interface XDR successively.Simultaneously the present invention has flexible expansion ability, can according to other association analysis demands of demand flexible expansion of the development of network and business.
In order to realize the association of big data quantity, the present invention adopts distributed way deal with data, the original XDR utilizing multiple receiver (network element data reception server) simultaneously to receive data collection layer to report, each receiver only processes a part of data, thus has shared excessive data volume.Simultaneously in order to reduce the data pressure issuing follow-up sequence server, data are done reduction process at receiver place.Caching process is done haveing nothing to do with association process or repeating to issue the sort various types of messages of server at each receiver place, and only send the message of building table possibly, upgrading herein, or unduplicated query messages of trying one's best, thus greatly reduce the data volume mailing to follow-up sequence server.Owing to there is the situation that message sequencing is put upside down, if the order not adjusting message transmission directly associates, then cannot set up correct instant user profile relation, therefore need sequence server to arrange data according to message transmitting time, then send to core associated server.Associated server circulates according to the message of each interface of network, the correlation rule that setting is corresponding, after the association messages receiving the rear each interface of sequence, user-association process is carried out according to correlation rule, set up data relationship table, in time contingency table upgraded, when receiving association request msg, user profile can also be found from User relationship table, building backfill data-message.Backfill data-message is the message that the backfill data sent to network element data server form.Minimum in order to ensure message circulation, by the device identification in message, message after the backfill of specifying network element data reception server to send is combined, then sends to corresponding network element to receive processing server.After network element data reception server receives data, upgrade buffer memory, backfill message data, like this according to the backfill data returned after association, has filled out user profile by the XDR not with user profile, then has been distributed to user profile Distributor by user IMSI.
See Fig. 1, the embodiment of the present invention proposes to arrange network element data reception server, sequence server, associated server, user profile Distributor.During concrete enforcement, the number of network element data reception server, user profile Distributor can need to arrange according to distribution.For 3 network element data reception servers, 2 user profile Distributors, each interface XDR data of network element 1,2,3 input network element data reception server 1,2,3 respectively, network element data reception server 1,2,3 export extract to associate relevant each interface data and be all sent to sequence server, core associated server is sent to after the good data of sequence server arrangements, core associated server finds the user profile of association to build backfill data-message, turns back to corresponding network element and receives processing server; Network element receives processing server and backfill result is transferred to each network element data reception server to distribute, as there being 2 user profile Distributors in figure, be designated as by user's Distributor 1, by user's Distributor 2 respectively, by user's Distributor 1, by user's Distributor 2 respectively to follow-up each analyzing and processing server (as user in figure processes 1,2,3 ...) carry out corresponding distribution.Embodiment provide the method to core net each interface XDR data carry out user information correlation to comprise the following steps:
Step one, each network element data reception server receives the XDR data of each class interface from respective network elements respectively, searching user's information in local cache relation table, if inquire, then can directly obtain user profile and associate, after obtaining carrying the XDR data of user profile, enter step 5.If do not inquire, the data to receiving are needed to arrange.Extract and associate relevant data, be associated information cache, and remove that repeat or without the need to associating field, thus the necessary data that final associated server needs is screened, batch sends to sequence server after integrating.
Step one realizes as follows,
When receiving certain message and its associations is effective, then in the cache table that this associations is corresponding, first search the user profile in message, if find, just directly can backfill user profile, associate backfilling process and terminate; If do not find, then send to sequence server after the data received being arranged.
Being implemented as follows of embodiment:
Set up local cache relation table in advance.Take MME as the local cache relation table of user-association item be example, this relation table is set up with Hash table structure, and wherein Hash key assignments and MME associations, is worth for certain user profile intelligent pointer, comprises the relevant information of IMSI, as IMEI, MSISDN.
After local cache relation table is built up, when receiving a UU message and MME value is effective, then in MME cache table, first search the MME value in message, if find, just directly can backfill user profile, associate backfilling process and terminate; If do not find, then send to sequence server after the data received being arranged, enter step 2.
It should be noted that, if receive S11 message or S1MME message, be not directly inquire about, and will go to set up or upgrade local user's relation cache table (if there is this associations in local relation table as building table message, then upgrade, if nothing, then set up), then send to sequence server after the data received being arranged, enter step 2.
Step 2, sequence server receives each interface data sent from each network element data reception server, time (i.e. the end time of the message inside) sequence that the message contained by packet sends, send corresponding each interface message to associated server, guarantee like this to send to the message of associated server to be that the time is orderly.Step 2 realizes as follows,
First orderly map table is set up, the prioritisation of messages received is joined in ordered list, the map token storing ordered message in embodiment is dataMap_, every predetermined time interval as 0.5 second inspection once, if directly the data in dataMap_ are all sent, at next 0.5 second, what insert dataMap_ may be the data (key assignments is within the scope of first dataMap_ sent for 0.5 second) that key assignments is less, sent to the data of associated server like this and incomplete.In order to maximum integral data, when patrolling each time, be not that the data in dataMap_ are all sent, but remain portion of time comparatively after data, participate in sequence below.
Being implemented as follows of embodiment:
First set up orderly map table, the C++ data structure definition storing ordered message is as follows:
map<u64, list<CollectInfo_t> > dataMap_;
The major key of map is the time (data format is u64) that message sends, and the value value of map is the messaging list sent the same time, and messaging list is kept in list<CollectInfo_t>.List<CollectInfo_t> is self-defined structure, preserves the list that the same time sends message.
The message received is joined in ordered list, every inspection in 0.5 second once, when patrolling each time, being not that the data of dataMap_ in this 0.5 second are all sent, but remaining a part of data, retain data according to as follows:
Maximum Jian Zhi – 2.5 seconds (2.5 is maximum permission Message Time Delay)=threshold value D of dataMap_ in 0.5 second, when specifically implementing, those skilled in the art can preset the value of threshold value D voluntarily.
In 0.5 second, the key assignments of dataMap_ is less than the part of threshold value D, can send to associated server, and in 0.5 second, the key assignments of dataMap_ is greater than the part of threshold value D, continues to be retained in dataMap_, participates in sequence below.
Step 3, associated server receives each interface message (this message is through process such as the screening of data collection server and the sequences of sequence server) that sequence server sends.Association refers to and the data of each distinct interface is associated by the correlation (i.e. user related information) between signaling procedure, user related information refers at synchronization, uniquely can only confirm the information of a user, and other interface message can be found by this information.User-association can be carried out according to these user's related news in advance during concrete enforcement, and set up User relationship table, whenever newly receiving each interface message that sequence server sends, contingency table be upgraded.When newly receiving each interface message, illustrating and receiving association request, then from User relationship table, finding user profile, build backfill data-message, then sending to corresponding reception server needing the message of backfill to combine.Step 3 realizes as follows,
Steps A 01, the message flow according to each interface of network transfers the registration of Party membership, etc. from one unit to another, and draws the retrievable association of each interface, sets up a kind of pattern of rational correlation inquiry;
Steps A 02, utilizes internal memory level various dimensions user message table to realize associating backfill fast.In order to ensure the promptness of data processing, take internal memory level to process the mode of regularly preserving in real time, be directly linked to user profile from multiple associations dimension simultaneously, thus improve the speed of association.In order to energy real-time query is to user profile, be that each associations sets up corresponding memory table, after receiving data, directly build table according to data type, upgrade or inquiry.
Being implemented as follows of embodiment:
Steps A 01, the message flow according to each interface of network transfers the registration of Party membership, etc. from one unit to another, and sets up a kind of pattern of rational correlation inquiry.Analyze each interface and turn over journey in the effect of core net and message flow, can draw the retrievable association of each interface, such as associations IMSI, MME, TMSI, MMECELL, IPv4, data entrained by IPv6, TEID are:
IMSI associations comprises IMSI(International Mobile Subscriber Identity, IMSI International Mobile Subscriber Identity), IMEI(International Mobile Equipment Identity, International Mobile Station Equipment Identification), MSISDN(Mobile Station Integrated Services Digital Number, mobile subscriber ISDN number) data item, but only have IMSI to be association key assignments;
MME(Mobility Management Entity, Mobility Management Entity) associations comprises MME_S1AP_ID, MME_Group_ID(MME group identifies), MME_Code(MME encodes) data item;
TMSI associations comprises TMSI(Temporary Mobile Subscriber Identity, interim identity) data item;
MMECELL associations comprises the unique subscriber identification of MME_S1AP_ID(MME side SI interface), eNB_ID(Evolved Node B, evolved node B), CELL_ID(community ID) and data item;
IPv4 associations comprises the IP address of 4 bytes;
IPv6 associations comprises the IP address of 16 bytes;
TEID associations comprises TEID(Tunnel Endpoint Identifier, Tunnel End Point Identifier) data item.
Therefore the associations of each interface is not identical, and those skilled in the art can specified associations item as the case may be.
Following interface is all the relevant interface of core net
UU interface: IMSI associations, MME associations, TMSI associations, MMECELL associations
X2 interface: MME associations
UEMR interface: MMECELL associations
S1MME interface: IMSI associations, MME associations, TMSI associations, IPv4 associations, IPv6 associations, TEID associations
S10/S11 interface: IMSI associations, IPv4 associations, IPv6 associations, TEID associations
S1U interface: IMSI associations, IPv4 associations, IPv6 associations, TEID associations
S6A interface: IMSI associations
SGS interface: 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 agreement, TEID(Tunnel Endpoint Identifier) refer to Tunnel End Point Identifier.
With reference to each interface protocol and inter-network messages circulation, draw and can be associated by the interface data of S1MME with S10/S11, therefore set up user profile relation table by S1MME and S10/S11 data, other interface data is only used for inquiring about incidence relation or upgrading user profile, and does not set up new user profile.The incidence relation of each interface is described below:
Can associating IMSI, IPv4, IPv6, TEID, MME/TMSI according to S1MME message, namely by IP/TEID or MME/TMSI, find user profile.
IMSI, IPv4, IPv6, TEID can be associated according to S10/S11 message, namely find user profile by IP/TEID.
Because S6A, SGS interface only has IMSI information, and there is no IMEI, MSISDN information, but other interface there is the corresponding relation of IMSI, IMEI, MSISDN, therefore obtained IMEI, MSISDN value of user by IMSI table, namely find user profile.
MMECELL and MME/TMSI/IMSI can be associated according to UU message, and UEMR interface only has MMECELL message, namely find user profile by the association of UU mouth.
When certain message contains multiple associations, suitable associations should be selected to determine user identity.Uniquely can determine that the degree of user is different according to each interface conjunctionn item, the preferential search order of associations of each interface is set as follows:
UU interface: IMSI > TMSI > MME
X2 interface: MME
UEMR interface: MMECELL
S1MME interface: IMSI > IP > TEID
S10/S11 interface: IMSI > IP > TEID
S1U interface: IMSI > IP > TEID
S6A interface: IMSI
SGS interface: IMSI
For UU interface polls, if there is IMSI, then first show searching user's information from IMSI, if not find and TMSI is effective, then continue through TMSI and show searching user's information, if not find and MME is effective, then continue through MME and show searching user's information.
Steps A 02, utilizes internal memory level various dimensions user message table to realize associating backfill fast.In order to ensure the promptness of data processing, take internal memory level to process the mode of regularly preserving in real time, be directly linked to user profile from multiple associations dimension simultaneously, thus improve the speed of association.
After receiving data, directly build table according to data type, upgrade or inquiry, because the data magnitude of S1-U interface is more much larger than other interface, therefore except adopting mode provided by the invention, also can do independent process to the data of this interface during concrete enforcement, such as, set up buffer memory relation table by the IP associations of S11 interface, S1U interface XDR data are according in IP association, in backfill after user profile, then be distributed to user profile Distributor by user IMSI.
In order to energy real-time query is to user profile, be that each associations sets up corresponding memory table, after receiving data, directly build table according to data type, upgrade or inquiry.See 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
As in Fig. 2, in IMSI table, according to imsi=3, user profile 1 can be found, equally, user profile 1 can be found according to ipv4=6 in Mme=5, IPv4 table in tmsi=4, MME table in TMSI table; And in tmsi=8, expired MME table, in Mme=3, expired IPv4 table, ipv4=2 etc. was once the value in user profile 1 in expired TMSI table, but the associations be updated afterwards, all user profile 1 will be pointed within a period of time, to support that those interface data still using time value carry out user-association, the type of action such as user profile 2 are identical.
Fastest in order to make to build the internal memory operations such as table, inquiry, taking Hash table structure to store memory table corresponding to each associations, is that the user message table of associations foundation is example with MME:
This table is set up with Hash table structure, wherein Hash key assignments and associations MME_ID_t, value is certain user profile intelligent pointer, because intelligent pointer can carry out pointer operation easily, and without the need to comprehending the release of object, therefore intelligent pointer is used when not having key to point to certain user profile, can automatically to discharge this user profile herein.
When certain user profile exists multiple associations, in the table corresponding to each associations, all must there is corresponding key assignments and point to same user profile object.When the associations of user profile changes, its key assignments corresponding relation also will change thereupon.For guaranteeing the correctness of the corresponding relation of user, to immediately backfill when inquiring user profile.
It should be noted that Hash table needs to carry out cycle cleaning, when there is not at least two key items in user profile, this user profile just cannot be used for doing inquiry association, so will delete this key assignments relation and user profile.Occur that user profile lacks the reason of associations, be generally because the association entry value in user profile, changed the user pointing to other.
Step 4, network element data reception server receives the backfill message of associated server, according to backfill message, upgrades local cache relation table, simultaneously upper for the backfill of the interface message of correspondence user profile, XDR Data dissemination gained being carried user profile sends to each user profile Distributor.
The realization that embodiment upgrades local cache relation table is as follows:
First be separated the backfill message received, from message table, find origination message, then according to the user profile backfilled, upgrade customer relationship cache table.
It should be noted that, the IMSI table of local cache relation table can exist for a long time, and other relation table, because the term of validity of this associations is limited, and cannot learn whether this value has pointed to other user profile, so need at set intervals to remove, only retain the corresponding relation of nearest a bit of time.
Step 5, each user profile Distributor receives the XDR data of carrying user profile, and carry out delivery according to IMSI in user profile, be distributed to follow-up analyzing and processing server by user, user's correlation analysis so below just can take distributed implementation.
Above content is in conjunction with concrete execution mode further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
