[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more comprehensive and complete and will fully convey the concept of the example embodiments to those skilled in the art.

[0033] In addition, the described features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted.

[0034] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0035] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0036] Call tracing refers to locating the origin of a call during a communication call by a reasonable method. In the relevant technologies in this field, the telephone tracing analysis technology is implemented based on the signaling monitoring system. Since the telephone is forwarded segment by segment in the network, the tracing is mainly based on the six-tuple of each signaling segment for correlation and concatenation. The six-tuple includes the start time, end time, entry point information, exit point information, caller information, called party information and other information of the specific call. The traceability analysis technology based on the signaling monitoring system has the following problems, resulting in poor usability and difficulty in large-scale application: 1. Signaling data must be collected step by step throughout the entire process. The full-process signaling data collection requires extremely high technology, but due to the large variety of systems and the provincial construction, there is no linkage between provinces. If the caller and the called party are in different provinces, the call records cannot be associated, and the association and tracing fail if the information is incomplete; 2. The data association success rate is extremely low, and it is difficult to associate multiple signaling protocols and cross-devices. At the same time, it will be seriously affected by factors such as business number changes and timestamp deviations; multiple protocols and multi-field identifiers are uneven and time-consuming to process; 3. This method has low analysis efficiency and high consumption. Each call must match N passed bureaus * M tuples, which requires huge calculations.

[0037] Based on the problems existing in the related art, a call tracing method is proposed in one embodiment of the present disclosure. Figure 1 A flowchart of a call tracing method is shown, such as Figure 1 As shown, the call tracing method includes at least the following steps:

[0038] Step S110: Obtaining original call record data;

[0039] Step S120: extracting the originating network identifier of the communication call process from the original call record data, wherein the originating network identifier is the network identifier of the network initiating the communication call process;

[0040] Step S130: Obtaining the originating network information corresponding to the originating network identifier, or the originating network information and voice relay information corresponding to the originating network identifier from the network identifier information allocation relationship table according to the originating network identifier, wherein the network identifier information allocation relationship table stores the correspondence between the network identifier and the originating network information, or stores the correspondence between the network identifier and the originating network information and the voice relay information.

[0041] The call tracing method in the embodiment of the present disclosure, on the one hand, simplifies the analysis content. It only needs to extract the originating network identifier in the original call record data, and obtain the originating network information, or the originating network information and the voice relay information according to the originating network identifier, thereby avoiding the situation where the call tracing is inaccurate due to the change of the caller's number information during the communication call, and improving the accuracy of call tracing; on the other hand, there is no need to obtain signaling data in the signaling monitoring system, which solves the problem that call records of cross-provincial communications cannot be associated, and at the same time reduces the overhead of call tracing, reduces the investment in system hardware, and improves the efficiency of call tracing.

[0042] It should be noted that the call tracing method of the exemplary embodiment of the present disclosure can be executed by a server, and the call tracing device corresponding to the call tracing method can also be configured in the server. In addition, it should be understood that the terminal device (for example, a mobile phone, a tablet, etc.) can also implement the various steps of the call tracing method, and the call tracing device corresponding to the call tracing method can also be configured in the terminal device.

[0043] In order to make the technical solution of the present disclosure clearer, each step of the call tracing method is described below.

[0044] In step S110, original call record data is obtained.

[0045] In an exemplary embodiment of the present disclosure, one or more pieces of original call bill data are obtained in the billing system. The multiple pieces of original call bill data may include all the original call bill data in the billing system, or may include the original call bill data corresponding to all communication call processes of a certain calling party or a certain called party in the billing system, or may include all the original call bill data corresponding to a certain time period or a certain area in the billing system; one piece of original call bill data may include the original call bill data corresponding to a certain communication call process of a certain calling party or a certain called party in the billing system. Of course, the original call bill data may be obtained according to the actual application scenario, and the present disclosure does not specifically limit this.

[0046] It should be noted that the billing system is a system in the telephone exchange that records information related to user communication charges. The billing system will generate original call bill data based on the communication call information of each user's communication call process. One original call bill data corresponds to a communication call process, and each original call bill data includes the caller's number information, the called party's number information, the call request timestamp, the communication start time, the communication end time, the originating network identifier, the terminating network identifier, etc.

[0047] In addition, if the called party does not connect to the call during the communication call, the original call record data includes the calling party's number information, the called party's number information, the call request timestamp, the originating network identifier, the terminating network identifier, etc.

[0048] In an exemplary embodiment of the present disclosure, original call data can be obtained from a billing system according to communication call information, and the communication call information may include the number information, communication start time, and communication end time of the calling party, or the number information, communication start time, and communication end time of the called party; the communication call information may also include the number information, call request timestamp of the calling party, or the number information, call request timestamp of the called party, etc. The communication call information may be determined according to the actual application scenario, and the present disclosure does not specifically limit this.

[0049] For example, if the communication call information is the caller's number information and the call request timestamp, the caller's number information is matched with the original call bill data in the billing system to obtain multiple original call bill data corresponding to the caller's number information; then the call request timestamp is matched with the multiple original call bill data corresponding to the caller's number information to obtain the original call bill data that matches the call request timestamp among the multiple original call bill data corresponding to the caller's number information. Alternatively, the call request timestamp may be matched with the original call bill data in the billing system first to obtain multiple original call bill data; then the caller's number information may be matched with the multiple original call bill data to obtain the original call bill data that matches the caller's number information. Alternatively, the caller's number information and the call request timestamp may be matched with the original call bill data in the billing system at the same time to obtain the original call bill data that matches the caller's number information and the call request timestamp.

[0050] In addition, the calling party's number information can be determined first through the called party's number information, communication start time and communication end time, and then the original call bill data can be obtained in the billing system based on the calling party's number information, communication start time and communication end time.

[0051] In step S120, the originating network identifier of the communication call process is extracted from the original call record data, wherein the originating network identifier is the network identifier of the network that initiates the communication call process.

[0052] In an exemplary embodiment of the present disclosure, the original call record data may also include the calling party's number information field, the called party's number information field, the call request timestamp field, the communication start time field, the communication end time field, the originating network identification field, the terminating network identification field, etc. corresponding to the communication call process.

[0053] Among them, the calling party's number information field corresponds to the calling party's number information, the called party's number information field corresponds to the called party's number information, the call request timestamp field corresponds to the call request timestamp, the communication start time field corresponds to the communication start time, the communication end time field corresponds to the communication end time, the originating network identification field corresponds to the originating network identification, and the terminating network identification field corresponds to the terminating network identification.

[0054] For example, if the communication call process satisfies IMS (IP Multimedia Subsystem, IP multimedia technology), and the signal transmission in the communication call process satisfies SIP (Session Initiation Protocol, Session Initiation Protocol), the originating network identification field in the original call record data can be the "OriginatingIOI" field, and the originating network identification field corresponding to the originating network identification field can be "1731.xt.hu.ctcims.cn"; the terminating network identification field can be the "TerminatingIOI" field, and the terminating network identification field corresponding to the terminating network identification field can be "mgcfl.hu.ctcims.cn". Of course, the field identifiers of each field in the original call record data can be represented by any special characters and / or non-special fields alone or in combination, and the present disclosure does not make specific limitations on this.

[0055] It should be noted that a communication call process will access multiple networks. During the communication call process, the communication session information between the caller and the called party is forwarded through multiple networks. Specifically, a communication call process may include the following steps: First, the caller initiates a call request on the caller's terminal device, and the communication call process begins. The call request is transmitted between the initiating network, one or more intermediate networks, and the terminating network, and finally reaches the called party's terminal device; then, the called party triggers the access communication button on the called party's terminal device, and the caller and the called party start a communication session. The communication session information between the caller and the called party is transmitted through the initiating network, one or more intermediate networks, and the terminating network. Finally, when the caller or the called party triggers the end communication button on the corresponding terminal device, the entire communication call process ends.

[0056] Among them, the entire communication call process is completed through signal transmission between the initiating network, one or more intermediate networks, and the terminating network. The originating network identifier of the communication call process is the network identifier of the initiating network during the communication call process, and the terminating network identifier of the communication call process is the network identifier of the terminating network during the communication call process.

[0057] In an exemplary embodiment of the present disclosure, in the original call log data corresponding to the communication call process, the originating network identification field is queried, and the originating network identification corresponding to the originating network identification field is extracted. The originating network identification is the originating network identification of the communication call process.

[0058] For example, in the original call bill data, the "OriginatingIOI" field is found, and the originating network identifier "1731.xt.hu.ctcims.cn" corresponding to the "OriginatingIOI" field is extracted. Of course, according to the actual application scenario, when the billing system generates the original call bill data, the network identifier of the originating network, that is, the originating network identifier field of the originating network identifier will be different, and this disclosure does not make specific limitations on this.

[0059] Through the call tracing method of this embodiment, inaccurate call tracing caused by changes in the caller's number information during the communication call can be avoided. Since the originating network identifier in the original call bill data is configured by the network device corresponding to the originating network information or voice relay information, it is unique, thereby improving the accuracy of call tracing.

[0060] In step S130, the originating network information corresponding to the originating network identifier, or the originating network information and voice relay information corresponding to the originating network identifier, is obtained from the network identifier information allocation relationship table according to the originating network identifier, wherein the network identifier information allocation relationship table stores the correspondence between the network identifier and the originating network information, or stores the correspondence between the network identifier and the originating network information and the voice relay information.

[0061] In an exemplary embodiment of the present disclosure, the originating network information corresponding to the originating network identity is acquired from a network identity information allocation relationship table according to the originating network identity, wherein the network identity information allocation relationship table stores the correspondence between the network identity and the originating network information.

[0062] Specifically, the originating network identifier is matched with the network identifier in the network identifier information allocation relationship table; when the originating network identifier matches the network identifier in the network identifier information allocation relationship table, the originating network information corresponding to the network identifier in the network identifier information allocation relationship table is configured as the originating network information corresponding to the originating network identifier.

[0063] Wherein, in the network identification information allocation relationship table, there is a network identification corresponding to the originating network identification, and the originating network information corresponding to the network identification is used as the originating network information corresponding to the originating network identification. The originating network information includes the location information corresponding to the originating network. When the communication call process is a personal communication, the originating network is the initiating network of the communication call process.

[0064] in addition, Figure 2 A schematic diagram of a method flow for configuring a network identification information allocation relationship table according to an embodiment of the present disclosure is shown. Figure 2 As shown, the process at least includes steps S210 to S220, which are described in detail as follows:

[0065] In step S210, the source network information is obtained, and a network identifier corresponding to the source network information is configured according to the source network information.

[0066] In an exemplary embodiment of the present disclosure, the originating network information is obtained in the operator resource system, and the network identifier corresponding to the originating network information is configured according to a preset rule. Among them, the preset rule can be to configure the network identifier according to the pinyin of the first letter of the location information corresponding to the originating network. For example, if the location information corresponding to the originating network is "Hunan", the network identifier corresponding to the originating network information is configured as "hu.ctcims.cn". Of course, it is also possible to configure the network identifier according to the full alphabetical name of the location information corresponding to the originating network, or use special characters or non-special characters to represent the location information corresponding to the originating network, and configure the network identifier according to special characters or non-special characters. The present disclosure does not make specific limitations on this.

[0067] It should be noted that the operator resource system stores the corresponding originating network information of each region, and the network identifier corresponding to the originating network information can be configured in the operator resource system. In addition, users in each region can activate the voice relay service in the operator resource system, and the operator resource system can also store the corresponding originating network information of each region and one or more voice relay information corresponding to the originating network information. Similarly, the network identifier corresponding to the voice relay information can also be configured in the operator resource system.

[0068] In step S220, a network identification information allocation relationship table is configured according to the source network information and the network identification corresponding to the source network information.

[0069] In an exemplary embodiment of the present disclosure, the generated network identification information allocation relationship table is pre-stored in a data structure, and the source network information and the network identification corresponding to the source network information are stored in the network identification information allocation relationship table in the form of key-value pairs.

[0070] The network identifier is stored as a key value in the network identifier information allocation relationship table, and the source network information corresponding to the network identifier is stored as a value in the network identifier information allocation relationship table.

[0071] In an exemplary embodiment of the present disclosure, a network identifier corresponding to the originating network information is sent to a network device corresponding to the originating network information; when the network device corresponding to the originating network information is accessed during a communication call, the originating network identifier of the communication call process is configured through the network device corresponding to the originating network information.

[0072] Specifically, the network device corresponding to the originating network information may be an electronic device such as a repeater, a gateway, a switch, etc. corresponding to the originating network. The network device may receive a network identifier and use the network identifier as relay configuration data. When the terminal device of the caller in the communication call process is connected to the network device, the network device may configure the corresponding network identifier as the originating network identifier in the original call list data. In addition, the network identifier information allocation relationship table may be sent to all network devices so that the network devices configure the originating network identifier according to the data in the network identifier information allocation relationship table.

[0073] In an exemplary embodiment of the present disclosure, after obtaining the originating network information corresponding to the originating network identifier from the network identifier information allocation relationship table according to the originating network identifier, the originating network information corresponding to the originating network identifier is backfilled into the original call record data of the call process.

[0074] It should be noted that all original call bill data in the billing system can be obtained, and the originating network identifiers corresponding to all original call bill data can be extracted. The originating network identifiers corresponding to all original call bill data can obtain the originating network information corresponding to all original call bill data in the network identifier information allocation relationship table, and the originating network information can be backfilled into the original call bill data. After the originating network information is backfilled into the original call bill data, call tracing can be performed directly from the original call bill data corresponding to each communication call process.

[0075] In an exemplary embodiment of the present disclosure, the originating network information and voice relay information corresponding to the originating network identifier are obtained from a network identifier information allocation relationship table according to the originating network identifier, wherein the network identifier information allocation relationship table stores the correspondence between the network identifier and the originating network information and the voice relay information.

[0076] Specifically, the originating network identifier is matched with the network identifier in the network identifier information allocation relationship table; when the originating network identifier matches the network identifier in the network identifier information allocation relationship table, the originating network information and voice relay information corresponding to the network identifier in the network identifier information allocation relationship table are configured as the originating network information and voice relay information corresponding to the originating network identifier.

[0077] Among them, there is a network identifier corresponding to the originating network identifier in the network identifier information allocation relationship table, and the originating network information and voice relay information corresponding to the network identifier are used as the originating network information and voice relay information corresponding to the calling network information.

[0078] It should be noted that the voice relay information may include the voice relay platform identifier, and may also include the location information, enterprise or group name information, etc. corresponding to the voice relay platform. When the communication call process is a fixed-line communication through a voice relay platform, the initiating network of the communication call process is the network corresponding to the voice relay platform. When communicating through a voice relay platform, the voice relay platform accesses the originating network to implement the communication call process.

[0079] in addition, Figure 3 A schematic diagram of a method flow for configuring a network identification information allocation relationship table according to another embodiment of the present disclosure is shown. Figure 3 As shown, the process at least includes steps S310 to S320, which are described in detail as follows:

[0080] In step S310, the originating network information and the voice relay information within the coverage of the originating network are obtained, and a network identifier corresponding to the voice relay information is configured according to the originating network information and the voice relay information.

[0081] In an exemplary embodiment of the present disclosure, the originating network information and the voice relay information within the coverage of the originating network are obtained in the operator resource system. One originating network information may correspond to one or more voice relay information, and one voice relay information corresponds to unique originating network information.

[0082] Specifically, the network identifier corresponding to the voice relay information can be configured according to preset rules, wherein the preset rules can be to configure the network identifier according to the network identifier corresponding to the originating network and the voice relay platform identifier. For example, if the location information corresponding to the originating network is "Changsha, Hunan", the network identifier corresponding to the originating network information is "cs.hu.ctcims.cn", and the unique identifier of the voice relay platform corresponding to the voice relay information is "1731", then the network identifier corresponding to the voice relay information is "1731.cs.hu.ctcims.cn". Of course, the unique identifier of the voice relay platform corresponding to the voice relay information can also be configured according to any special characters or non-special characters alone or in combination, and the network identifier corresponding to the voice relay information can be configured according to the unique identifier of the voice relay platform and the network identifier corresponding to the originating network, and the present disclosure does not make specific limitations on this.

[0083] Among them, the enterprise or group opens a voice relay service in the operator's resource system. Multiple members of the enterprise or group can communicate internally through the voice relay platform, and can also access the source network through the voice relay platform for external communication.

[0084] In addition, the operator resource system can also configure the network identifier corresponding to the voice relay information according to the source network information and voice relay information, and directly obtain the network identifier configured by the operator resource system, the voice relay information corresponding to the network identifier, and the source network information corresponding to the network identifier.

[0085] In an exemplary embodiment of the present disclosure, voice relay information and originating network information of the originating network where the voice relay information is located are obtained, and a network identifier corresponding to the voice relay information is configured according to the voice relay information and the originating network information of the originating network where the voice relay information is located.

[0086] In step S320, a network identification information allocation relationship table is configured according to the voice relay information, the originating network information corresponding to the voice relay information, and the network identification corresponding to the voice relay information.

[0087] In an exemplary embodiment of the present disclosure, the voice relay information, the originating network information corresponding to the voice relay information, and the network identification corresponding to the voice relay information may be stored in a network identification information allocation relationship table in the form of key-value pairs.

[0088] The network identifier is stored as a key value in the network identifier information allocation relationship table, and the originating network information and voice relay information corresponding to the network identifier are stored as value values ​​in the network identifier information allocation relationship table.

[0089] In an exemplary embodiment of the present disclosure, the network identification information allocation relationship table can be provided by FTP transmission or data table import, and a network identification information allocation relationship table is created and maintained with the network identification as a key and the source network information and voice relay information corresponding to the network identification as values. Table 1 shows a network identification information allocation relationship table, which includes the network identification, the source network information corresponding to the network identification, and the voice relay information corresponding to the network identification.

[0091] Network Identity Source network information Voice relay information 1731.xt.hu.ctcims.cn Hunan Xiangtan Xiangtan City 1731 3919.cs.hu.ctcims.cn Changsha, Hunan Changsha City 3919 4393.cs.hu.ctcims.cn Changsha, Hunan Changsha City 4393 1432.zjj.hu.ctcims.cn Zhangjiajie, Hunan Zhangjiajie 1432

[0092] In addition, the network identification information allocation relationship table may also include a situation where a certain network identification corresponds to the originating network information and the voice relay information is empty. At this time, the communication call process may be a personal communication. Whether it is a personal communication or a platform communication with a voice relay service enabled, the call tracing method in the above embodiment can be used to obtain the originating network information corresponding to the communication call process, or the originating network information and the voice relay information.

[0093] In an exemplary embodiment of the present disclosure, a network identifier corresponding to the voice relay information is sent to a network device corresponding to the voice relay information; when the network device corresponding to the voice relay information is accessed during a communication call, the originating network identifier of the communication call process is configured through the network device corresponding to the voice relay information.

[0094] Specifically, the network device corresponding to the voice relay information can be a repeater, gateway, switch or other electronic device in the voice relay platform, or a repeater, gateway, switch or other electronic device corresponding to the originating network corresponding to the voice relay information. The network device can receive the network identifier and the voice relay information corresponding to the network identifier, and use the network identifier as the voice relay configuration data of the voice relay information. When the terminal device of the caller in the communication call process accesses the network device through the voice relay platform, the network device can configure the network identifier corresponding to the voice relay platform as the originating network identifier in the original call list data. In addition, the network identifier information allocation relationship table can also be sent to all network devices, so that the network devices can configure the originating network identifier according to the data in the network identifier information allocation relationship table.

[0095] In an exemplary embodiment of the present disclosure, the originating network information and voice relay information corresponding to the originating network identifier are backfilled into the original call record data.

[0096] It should be noted that all original call bill data in the billing system can be obtained, and the originating network identifiers corresponding to all original call bill data can be extracted. The originating network identifiers corresponding to all original call bill data can obtain the originating network information and voice relay information corresponding to all original call bill data in the network identifier information allocation relationship table, and the originating network information and voice relay information can be backfilled into the original call bill data. After the originating network information and voice relay information are backfilled into the original call bill data, call tracing can be performed directly from the original call bill data corresponding to each communication call process.

[0097] In an exemplary embodiment of the present disclosure, Figure 4 A flow chart of a call tracing method according to an embodiment of the present disclosure is shown as follows: Figure 4 As shown, the process at least includes steps S410 to S430, which are described in detail as follows:

[0098] In step S410, in response to the call request of the calling party, the call signaling record of the calling party is obtained from the signaling monitoring system, and the originating network identifier corresponding to the calling party is extracted from the call signaling record.

[0099] In an exemplary embodiment of the present disclosure, the call request may be triggered by the caller inputting the number information of the called party on the terminal device of the caller and then triggering a call button. After responding to the call request of the caller, the signaling monitoring system generates a call signaling record corresponding to the caller in real time, and the call signaling record includes the number information of the caller, the number information of the called party, the call request timestamp, the originating network identifier, the terminating network identifier and other information.

[0100] In addition, the caller's call signaling record can be obtained from the signaling monitoring system in response to the callee's request for tracing, and the originating network identifier of the caller can be extracted from the call signaling record. The callee's request for tracing can be triggered by a tracing button on the terminal device before or after the callee connects to the session.

[0101] In step S420, the originating network identifier is matched with the network identifier in the network identifier information allocation relationship table to obtain the originating network information and voice relay information corresponding to the originating network identifier.

[0102] In an exemplary embodiment of the present disclosure, a network identification information allocation relationship table is preconfigured according to the originating network information, the voice relay information, and the corresponding network identification.

[0103] In step S430, the originating network information and the voice relay information are sent to the called party, so that the terminal device corresponding to the called party displays the originating network information and the voice relay information.

[0104] In an exemplary embodiment of the present disclosure, the network identification information allocation relationship table is sent to the signaling monitoring system, so that the signaling monitoring system adds the originating network identification to the call signaling record when receiving the call request from the calling party.

[0105] The call tracing method of this embodiment can obtain the caller's originating network identifier in the signaling monitoring system when receiving the call request from the caller, thereby realizing real-time tracing during the communication call process, which is of great significance in the practical application of combating harassment and fraudulent calls.

[0106] The following is a detailed description of the call tracing method in this example implementation method in combination with a specific scenario. In a specific application scenario, after receiving a harassing call, user A seeks tracing from the communication service provider. Since the caller number information displayed on user A's terminal device is likely to be counterfeit number information, it is not possible to directly trace the caller number information. The only known information is user A, that is, the number information of the called party, the communication start time, and the communication end time. Figure 5 A flow chart of a call tracing method in a specific embodiment of the present disclosure is shown. Figure 5 As shown, the process at least includes steps S510 to S530, which are described in detail as follows:

[0107] In step S510, the original call bill data list of user A is obtained in the billing system, and the communication start time and / or communication end time are matched with multiple original call bill data in the original call bill data list to determine the target original call bill data.

[0108] The target original call record data is the original call record data corresponding to the communication call process between user A and the harassing party.

[0109] In addition, the real number information of the harassing party can be determined according to the number information of the called party, the communication start time and the communication end time, and the target original call bill data can be obtained in the billing system according to the number information of the harassing party and the communication start time or the communication end time.

[0110] In step S520, the originating network identifier in the target original call record data is extracted.

[0111] Among them, the billing system will generate the original call bill data of the communication call process in the original call bill data list corresponding to the calling party and the called party in the communication call process.

[0112] In step S530, the originating network identifier is matched with a pre-configured network identifier information allocation relationship table to determine the originating network information and voice relay information corresponding to the originating network identifier.

[0113] If the originating network identifier in the target original call log data is "1731.xt.hu.ctcims.cn", the originating network identifier is matched with Table 1, and the originating network information corresponding to the originating network identifier is "Hunan Xiangtan", and the voice relay information is "Xiangtan 1731".

[0114] It should be noted that the communication service provider includes a billing system, an operator resource system, and a call tracing system, and data can be exchanged between the billing system, the operator resource system, and the call tracing system. The call tracing system can also be integrated with the billing system or the operator resource system, or it can be independent of the billing system and the operator resource system, and this disclosure does not specifically limit this.

[0115] The call tracing method of this embodiment simplifies the analysis content. It only needs to extract the originating network identifier in the original call record data of the communication call process, and match the originating network identifier with the pre-configured network identifier information allocation relationship table to obtain the originating network information and voice relay information of the communication call process, thereby realizing accurate tracing.
