Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The Terminal in the embodiment of the present invention may be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), an MTC (machine type communication) Terminal, and the like.
In the embodiment of the invention, data acquisition equipment in a data acquisition layer realizes access and acquisition of Uu, X2, S1, S11, S10, SGs, S6a, S5/S8 and other interfaces and firewall data, and generates the original xDR of each interface. The data acquisition layer reports the original xDR and the original code stream data to the data decoding layer, and the data processing equipment in the data decoding layer completes analysis, association, backfill and synthesis of the original xDR reported by the data acquisition layer. For example, backfill operation is performed on the single-interface xDR reported by the data acquisition equipment, so that a vacant field in the single-interface xDR is completed, and a complete single-interface xDR is generated; or associating a plurality of single-interface xDRs to generate a synthesized xDR. And the data statistical equipment analyzes and counts according to the single-interface xDR and the synthetic xDR.
The S1-MME interface is an interface between a base station and an MME (Mobility Management Entity), and is used for transmitting session Management and Mobility Management information, that is, signaling plane or control plane information.
The X2 interface is an interface between base stations and supports direct transmission of data and signaling.
The Uu interface is an interface between a base station and a terminal, and is used for performing decision execution of broadcast paging and RRC (Radio resource control) connection, handover and power control, processing management and control information of Radio resources, processing baseband and Radio frequency processing information, and the like.
The Sv interface is an interface between the MME and a Mobile Switching Center MSC (Mobile Switching Center), and is used to transmit information related to SRVCC.
The Gm interface is an interface between the terminal and a P-CSCF (Proxy-Call Session Control Function), and is used to transmit an SIP signaling message between the terminal and the IMS.
When initiating a VoLTE session service, a terminal needs to establish an RRC connection with a base station, and a signaling flow diagram of the terminal is shown in fig. 1. The terminal sends an RRC connection establishment request to the base station through the Uu interface, and the base station returns an RRC connection establishment response to the terminal through the Uu interface. The data acquisition equipment acquires the xDR of the RRC connection establishment service according to the signaling, and after the information such as the IMSI and the like is backfilled through the data decoding layer, the xDR can be further stored in a database.
The xDR may include information such as an IMSI (International Mobile Subscriber Identity), start time and end time of a service process, an IMEI (International Mobile Equipment Identity), and a user IP (Internet Protocol), which may be specifically shown in table 1.
The IMSI is used to identify a mobile Subscriber and is stored in an SIM (Subscriber Identity Module) card or an USIM (Universal Subscriber Identity Module) card, a network side network element HLR (Home Location Register) and a VLR (Visitor Location Register).
TABLE 1
The value of the field "procedure _ start _ time" of the RRC connection establishment procedure is the time when the terminal sends the RRC connection establishment request, and the value of the field "procedure _ end _ time" of the RRC connection establishment procedure is the time when the base station sends the RRC connection establishment response.
When the terminal initiates the VoLTE session service, PDN (Packet Data Network ) connection is also required, and a signaling flow transmitted through an S1-MME interface in the process is shown in fig. 2. And the base station sends a PDN connection request to the MME through an S1-MME interface, and the MME returns a default bearer activation request to the base station through an S1-MME interface. And after receiving the default bearer activation request, the base station sends a default EPS bearer activation request to the terminal, and if the terminal returns that the default bearer activation is successful, the base station sends the default bearer activation to the MME through the S1-MME interface. The data acquisition device acquires the xDR of the PDN connection service according to the signaling transmitted over the S1-MME interface, and further may store the xDR in a database. In the xDR, a value of a "procedure _ start _ time" field of a PDN connection procedure is a time when the base station sends a PDN connection request, and a value of a "procedure _ end _ time" field is a time when the base station returns a default bearer activation success.
However, for the Gm interface, the data acquisition device waits for the VoLTE session to end before acquiring xDR from the signaling transmitted by the Gm interface.
The data acquisition equipment acquires the xDR of each interface according to the signaling transmitted by each interface and stores the xDR in the database in time, and the data processing equipment acquires the corresponding xDR from the database and carries out information backfill.
The data acquisition device, the data processing device, and the data statistics device may be relatively independent devices, or may be function modules disposed on the same device, which is not limited in the present invention.
Referring to fig. 3, a schematic flow chart of an information backfilling method according to an embodiment of the present invention is shown, where the method includes the following steps:
step 301: the data processing equipment acquires a first xDR acquired from a VoLTE service signaling transmitted by a first interface.
The first interface may be an EPC control plane interface or an interface of an LTE access network. In particular, the first interface comprises one or more of the following interfaces:
-S1-MME interface
-X2 interface
-Uu interface
-Sv interface
In this step, the data processing device may obtain, from the database, the first xDR collected in the VoLTE service signaling transmitted from the first interface. The procedure of acquiring the first xDR from the VoLTE service signaling transmitted by the first interface may be referred to the foregoing embodiments, and is not repeated here.
As mentioned above, the first xDR includes xDR collected from request signaling and response signaling transmitted through the first interface when initiating VoLTE service. The xDR collected from the request signaling and the response signaling transmitted through the first interface when initiating the VoLTE service includes: IMSI, start time and end time of the service process.
Step 302: the data processing equipment acquires a second xDR acquired from a VoLTE service signaling transmitted by a second interface; the second interface is an interface between the terminal and the IMS, and the first interface is different from the second interface.
In this step, the data processing device may obtain, from the database, the second xDR collected in the VoLTE service signaling transmitted by the second interface, where the second xDR and the first xDR are preferably stored in different data tables of the same database.
Specifically, the second interface is a Gm interface.
The second xDR includes IMSI, call service type information, start time and end time of the call. The VoLTE call service types may be divided into voice calling, voice called, video calling, video called, and the like. The starting time of the service is VoLTE call starting time, and the ending time of the service is VoLTE call ending time.
Step 303: if the data processing equipment judges that the VoLTE service signaling from the first xDR and the VoLTE service signaling from the second xDR are the same session VoLTE service signaling, the data processing equipment backfills the call service type information in the second xDR into the first xDR.
The users of the VoLTE service signaling of the same session are necessarily the same, i.e. the IMSI is consistent. As described above, the first xDR acquired by the data acquisition device according to the signaling transmitted on the first interface can be acquired when the signaling transmission is completed, and the second xDR acquired according to the signaling transmitted on the second interface can be acquired only when the VoLTE session is completed. Thus, from a temporal point of view, the start time and the end time of a first xDR, which initiates the signaling acquisition of VoLTE traffic transmitted over the first interface, should precede the start time of a second xDR, which initiates the signaling acquisition of VoLTE traffic transmitted over the second interface.
Therefore, in the above step, when determining whether the VoLTE service signaling originated by the first xDR and the VoLTE service signaling originated by the second xDR are VoLTE service signaling of the same session: judging whether the IMSI in the first xDR is consistent with the IMSI in the second xDR, if not, determining that the VoLTE service signaling from the first xDR and the VoLTE service signaling from the second xDR are not VoLTE service signaling of the same session; if the two are consistent, the judgment can be continued according to the following modes:
mode 1: if the starting time of the call contained in the second xDR is later than the starting time of the service process contained in the first xDR, it is determined that the service signaling from which the first xDR originates and the service signaling from which the second xDR originates are VoLTE service signaling of the same session.
Mode 2: if the starting time of the call contained in the second xDR is later than the ending time of the service process contained in the first xDR, it is determined that the service signaling from which the first xDR originates and the service signaling from which the second xDR originates are VoLTE service signaling of the same session.
Optionally, after step 303, the data processing device may further perform KPI statistics according to the first xDR containing the VoLTE call type information. Such as the statistics of indexes of the voice caller S1-MME interface bearer establishment success rate, the voice caller S1 interface handover success rate, the voice caller X2 interface handover success rate, the voice caller SRVCC handover success rate, etc.
In the above embodiment of the present invention, after the first xDR and the second xDR are obtained, if it is determined that the obtained session service signaling from the first xDR and the obtained session service signaling from the second xDR are the same session service signaling, the session service type information in the second xDR is refilled into the first xDR. The information backfilling method provided by the embodiment of the invention can be completed in an off-line process, so that the obtained first xDR and the second xDR can be stored firstly, and the information backfilling is completed through the embodiment when the information backfilling is required to be executed, thereby avoiding the problems that when the information is backfilled on line, a large amount of information needs to be cached and the requirement on system hardware is high in the process of backfilling the information to the first xDR after the second xDR is acquired and reporting the first xDR to the data acquisition equipment due to the time difference between the acquisition of the first xDR and the acquisition of the second xDR.

The second obtaining module 402: the second xDR is used for acquiring a second xDR acquired from a VoLTE service signaling transmitted by a second interface; the second interface is an interface between the terminal and the IMS, and the first interface is different from the second interface.
The backfill module 403: and if the VoLTE service signaling from the first xDR and the VoLTE service signaling from the second xDR are judged to be the same session VoLTE service signaling, the method is used for backfilling the call service type information in the second xDR into the first xDR.
Specifically, the first interface includes one or a combination of the following interfaces:
-S1-MME interface
-X2 interface
-Uu interface
-Sv interface

the IMSI in the first xDR is consistent with the IMSI in the second xDR, and the starting time of the call contained in the second xDR is later than the ending time of the service process contained in the first xDR.
Further, the apparatus may further include a statistics module 404, configured to perform KPI statistics according to the first xDR including the VoLTE call type information after the backfilling module 403 backfills the call service type information in the second xDR into the first xDR.
