Description

Tracking area code update method, system, electronic device and storage medium

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a tracking area code update method, system, electronic device and storage medium.

Background technique

VoLTE (Voice over Long Term Evolution, Voice over Long Term Evolution) is an LTE (Long Term Evolution, Long Term Evolution) voice solution based on an IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) network.

When a VoLTE user is making a call, the IMS network needs to have the function of judging the city where the VoLTE user is making a call, so as to provide a basis for subsequent work such as whether the user is roaming, roaming charging, and roaming CDR presentation. According to the specification, this function is completed by SBC (Session Border Controller, session border controller).

The specific principle of SBC to determine the city where VoLTE users are on a call is as follows:

When the SBC receives a call initiated by a VoLTE user, it will actively send a signaling requesting location information to the LTE network, and the LTE network will eventually return the user's current TAC (Tracking Area Code, tracking area code) information to the SBC. TAC, and the TAC configuration table configured by its own network element (the TAC configuration table includes the correspondence between each TAC and the city area code), map the city area code corresponding to the TAC, and send the city area code to the IMS network through signaling. The network element is used for reference and is billed by the user.

In the process of using the above functions, the most critical part is the accuracy of the correspondence table between TAC and city area code in the SBC network element. In the prior art, the table is manually configured, and the configuration is based on whether the branch or wireless department is in the LTE network. When TAC is adjusted or TAC is newly added, the SBC maintenance and management personnel shall be manually notified to update the configuration table. However, in practical applications, due to frequent network changes and post changes of branch offices, wireless departments, and SBC maintenance managers, inaccurate TAC information on SBC network elements often occurs in the existing network.

The SBC receives the TAC returned by the LTE network, but finds that the TAC does not exist in the configuration table, that is, when the SBC fails to configure the relationship between the newly added TAC and the corresponding city area code, the SBC will add a new TAC corresponding to a default city area code (generally is a provincial capital city, such as Zhengzhou city area code 0371), according to the default city area code to determine whether the call is roaming, and use the default city area code as the billing basis for subsequent VoLTE calls.

It is understandable that the newly added TAC may happen to be the city area code of Zhengzhou, or it may not correspond to the city area code of Zhengzhou, but may correspond to other cities in Henan, such as Luoyang. If it is incorrectly mapped to the 0371 city area code, the Zhengzhou roaming information will be displayed on the subsequent CDR, and the charges will be charged according to the roaming in Zhengzhou.

It can be seen that when the LTE network adjusts the TAC or adds a new TAC, it does not notify the IMS network to modify the corresponding TAC in time, so the SBC defaults to specifying a corresponding city area code for the newly added TAC, and the default city area code is not the city where the user actually made the call. The area code of the new TAC is mistakenly mapped to the default city area code.

The solution in the prior art is to regularly update the corresponding table of the TAC, so as to reduce the probability of adding a new TAC to the SBC.

It is understandable that this solution is very difficult to implement. The TAC on the network side changes very frequently, and the process of checking the corresponding table of the TAC every time is complicated, not to mention the high-frequency verification, which costs manpower and time. It is very high, so it may still not be possible to detect changes in TAC in time in practical applications.

At present, there is no corresponding method to solve the above problems in the prior art.

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are the Inventive Embodiments are some of the embodiments, but not all of the embodiments.

Explanation of terms in the embodiments of the present invention:

VoLTE is an IP data transmission technology that does not require a 2G/3G network, and all services are carried on a 4G network, enabling the unification of data and voice services under the same network.

The tracking area corresponding to TAC (Tracking Area Code) is an area used for paging and location update, similar to the LAC (location area code, location area code) in the UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) network. concept. A TAC can uniquely identify an area, and an area corresponding to a TAC may contain one or more cells.

IMS is a brand-new multimedia service form, which can meet the needs of newer and more diversified multimedia services of current terminal customers, and is the core network control architecture of VoLTE services.

The SBC is located at the edge of the IMS core network and is the first node for terminals to access the VOLTE network. As the signaling agent and media agent of the IMS core network, the SBC is mainly used to isolate the access network from the IMS core network and implement NAT (Network Address Translation, Network address translation) traversal, firewall traversal, QOS (Quality of Service, quality of service) control, network security, TAC to city area code mapping and other functions.

FIG. 1 shows a schematic flowchart of a method for updating a tracking area code according to an embodiment of the present invention.

As shown in Figure 1, the method provided by the embodiment of the present invention specifically includes the following steps:

Step 11, obtain the call record of the preset time period, the call record includes the tracking area code TAC of the first caller and the city area code corresponding to the TAC of the first caller, and the TAC of the first caller is the session. The TAC sent by the LTE network received by the edge controller SBC, the city area code is obtained by the SBC according to the TAC of the first calling party and the correspondence between the TAC and the city area code stored by itself;

The device for updating the tracking area code in the embodiment of the present invention is an optimization platform of the IMS network, and is a third-party server with an independent processing function, and is applied to the embodiment of the present invention to verify and update the TAC.

Optionally, the extracted call records are call records of already connected calls, including ongoing calls and completed calls. The call record can describe the call connection process in detail, including: call type (such as answering billing, answering free, failure, timeout, etc.), start time, answering time, talk time, calling party number, calling TAC and corresponding city code, etc.

Optionally, the LTE network sends the user's VoLTE call to the IMS network, when the SBC receives the call initiated by the user, it requests location information from the LTE network, and the SBC receives the caller's TAC, and according to the received caller's TAC, and the The first corresponding relationship is described, the city area code corresponding to the calling TAC is mapped, and whether the user is roaming is determined according to the city area code. The subsequent signaling monitoring system extracts the caller's TAC and the city area code from the SBC to generate the call record, and the server obtains the call record for a preset time period from the signaling monitoring system.

Optionally, the signaling monitoring system is used to monitor the signaling in the network, and the whole system includes three modules of collection, processing and analysis. The acquisition module receives raw data from the VoLTE network, tracks various signaling messages in the same call process, obtains service information from these messages and analyzes it to form user call signaling records. The processing module generates a pre-statistical table according to the user's call signaling record, performs monitoring, and writes it into the database. The analysis module provides data query and analysis services.

Step 12: Determine the TAC of the second caller, the TAC of the second caller is the TAC of the first caller whose city area code matches the default city area code, and the default city area code is the SBC according to the newly added TAC, the default The designated city area code, and the newly added TAC is a TAC other than the TAC stored by the SBC;

Optionally, when the TAC received by the SBC is an unfamiliar, newly added TAC, of course, the SBC does not store the city area code of the newly added TAC, and a default city area code is directly specified for the newly added TAC, that is, the default area code of the city where the user is located is the default. City area code.

Optionally, the device for updating the tracking area code screens the TAC of the first calling party, and obtains the TAC of the first calling party whose city area code is the default city area code. When the corresponding city area code is the default city area code of the SBC, the call record is also judged according to the default city area code whether roaming occurs, and the call record may have a roaming judgment error.

There may be two situations in the call record: 1. For the SBC, the TAC of the second caller is the TAC stored by itself, and the default city area code is obtained by the SBC according to the storage mapping, that is, the actual call does correspond to the area code of the default city; 2. . For the SBC, the TAC of the second caller is the newly added TAC, and the default city area code is designated by the SBC.

Optionally, for the first case, the device for updating the tracking area code does not need to perform processing, and for the second case, the device for updating the tracking area code finds the newly added TAC according to the call record.

Step 13, determine the TAC of the third calling party, the TAC of the third calling party is the TAC of the second calling party that does not match the default TAC, and the default TAC is the TAC corresponding to the default city area code;

Optionally, further screening is performed for the TAC of the second calling party, and it is clarified which of the above cases belongs to the reason for being considered as the default city area code.

Optionally, the device for updating the tracking area code matches the TAC of the second calling party with the default TAC. If the TAC of the second calling party is the default TAC, it means that the call does occur in the default city area code, which belongs to the first situation above. , the TAC of the first caller in the call record has been correctly configured.

If the TAC of the second calling party is not any of the default TACs, it means that the TAC of the second calling party is a newly added TAC of the LTE network for the SBC, which belongs to the second case above. The city area code determined by the SBC in step 11 may be is wrong, the city area code in the call log may be wrong.

Optionally, the TAC of the second calling party that meets the conditions is screened out as the TAC of the third calling party.

Step 14: Send alarm information, where the alarm information includes the TAC of the third calling party, so that the system maintenance platform can determine the city area code corresponding to the TAC of the third calling party;

In the embodiment of the present invention, the SBC performs roaming judgment on the calling TAC according to the first correspondence between the TAC and the city code stored by itself, and generates a bill of calls corresponding to the call records for billing and displaying the place where the bill occurs. And since the TAC of the third calling party is unfamiliar to the SBC and a newly added TAC, neither the SBC nor the tracking area code update device stores the city area code corresponding to the TAC of the third calling party, and the System maintenance platform to determine.

Optionally, the system maintenance platform is an update device for maintaining the tracking area code of the TAC update in the LTE network, stores the latest TAC correspondence table, receives the TAC of the third calling party, and obtains the third calling party. The city area code corresponding to the TAC, and returns to the tracking area code update device.

Step 15: Receive the city area code corresponding to the third calling and called TAC returned by the system maintenance platform, and send it to the SBC for the SBC to add the third calling and called TAC and the corresponding TAC in the first corresponding relationship. city area code.

In the embodiment of the present invention, the TAC correspondence table of the SBC is no longer restricted at high frequency updates, but is focused on practical application scenarios. For each actual call record, the city area code corresponding to the first calling TAC of the call record is obtained by default. The TAC of the second caller with the city area code, screen out the call records that may have roaming misjudgments, and further determine the reason why the TAC of the second caller is the default city area code. When the default city area code is specified, an alarm message will be sent, and the system maintenance personnel will verify the TAC of the third caller in a targeted manner, and update and maintain the newly added TAC.

It is understandable that since the roaming misjudgment problem is closely related to the call records, it directly processes and analyzes each call record that may have a roaming misjudgment, and finds the problems caused by the SBC designation error in a targeted and real-time manner. Compared with simply updating the TAC correspondence table of the SBC, the maintenance efficiency is greatly improved.

An example is given below to illustrate the embodiment of the present invention:

When Henan SBC receives the newly added TAC returned by the LTE network, it directly specifies Zhengzhou's area code 0371 as the location of the VoLTE user, then 0371 is the default city area code, and obtains the TAC corresponding to 0371 stored on Henan SBC. The stored TAC corresponding to Zhengzhou is called the default TAC.

The update device of the tracking area code obtains the call records of Henan, extracts the TAC of the calling party, obtains the correspondence between the TAC and the city area code pre-stored by the SBC, simulates the city area code corresponding to the calling party's TAC on the SBC, and can predict the call record. The corresponding city area code.

If the calling TAC in the call record corresponds to Zhengzhou, there may be two situations: first, it is indeed Zhengzhou, and second, it is designated as Zhengzhou by default.

For each corresponding TAC of the calling party in Zhengzhou, according to the pre-established correspondence between the default TAC and the default city area code, determine whether the calling TAC matches the default TAC. There is no problem with the order; if it does not match, an alarm message will be sent so that the system maintenance platform can determine the corresponding city area code of the calling TAC, and add the calling TAC and the corresponding city area code.

The method for updating the tracking area code provided in this embodiment obtains the TAC of the second caller that may have a roaming misjudgment by screening the city area code corresponding to the first caller's TAC in the call record, and further determines the second caller's TAC. Whether the TAC is a newly added TAC, and if so, it is added to the first corresponding relationship of the SBC, so that the newly added TAC can be updated in a timely and efficient manner.

As shown in FIG. 1, on the basis of the above-mentioned embodiment, in the method for updating the tracking area code provided by another embodiment of the present invention, after the TAC of the second calling party is determined, the method further includes:

A call record information database is established, where the call record information database includes a call record corresponding to the TAC of the second calling party.

Optionally, the TAC of the second caller is the TAC of the first caller whose city area code matches the default city area code. There may be a roaming misjudgment problem, and the call records that may be misjudged by roaming are stored in the The call record information database is conducive to further screening of call records that may be misjudged by roaming in the future.

After the step of determining the TAC of the third calling party, the method further includes:

Delete the call record corresponding to the TAC of the second calling party that matches the default TAC in the call record information database.

It can be understood that, through the real-time maintenance of the call record information database, the memory can be released in time, which is convenient for the update device of the tracking area code to read the call records of the call record information database in real time.

Other steps in this embodiment are similar to those in the foregoing embodiment, and are not repeated in this embodiment.

In the method for updating the tracking area code provided by this embodiment, by establishing a call record information database, the call records that may be misjudged by roaming are stored in the call record information database, which is beneficial to subsequent call records that may be misjudged by roaming. Take further remedial action.

As shown in FIG. 1 , on the basis of the above embodiment, in the method for updating the tracking area code provided by another embodiment of the present invention, before the TAC of the third calling party is determined, the method further includes:

establishing a default information base, the default information base including the default TAC corresponding to the default city area code;

According to the TAC update table acquired in advance, the accuracy of the default information base is checked.

Optionally, the device for updating the tracking area code extracts the default city area code configured on the SBC. The sequence of this step is not specifically limited, as long as it is before the step 13.

Optionally, when the TAC returned by the LTE network received by the SBC is a newly added TAC and the city area code of the newly added TAC is not stored, a city area code is directly specified for the newly added TAC, that is, the area code of the city where the user is located is specified by default. The city area code, which is called the default city area code.

Optionally, after obtaining the default city area code, the tracking area code updating device uses the default city area code as an index to obtain the default TAC corresponding to the default city area code stored on the SBC.

Optionally, the default TAC is the TAC corresponding to the default city area code stored by the current SBC, and the area corresponding to the default TAC is indeed within the city range corresponding to the default city area code. A default city area code has multiple default TACs.

Optionally, a default information base is established according to the default city area code and the default TAC.

Optionally, after the establishment of the default information base is completed, the accuracy of the default TAC is checked one by one with the TAC update table stored by the wireless department of the LTE network to ensure that the default TAC really corresponds to the default city area code, to ensure that the information is accurate. .

Optionally, in step 15, after receiving the city area code corresponding to the third calling and called TAC returned by the system maintenance platform, the method further includes:

The TAC of the third calling party and the corresponding city area code are added to the default information base.

Optionally, after the verification of the default information base is completed, although the accuracy verification has been done, it can only be guaranteed that the default information base is accurate within a period of time. Because the verification process is complicated and the TAC changes very frequently, in practical applications It is impossible to guarantee that the default information base is always accurate, and there may be cases where the configuration of the newly added TAC default information base is missing.

Optionally, according to the newly added TAC obtained in step 15, the default database is updated in real time.

Other steps in this embodiment are similar to those in the foregoing embodiment, and are not repeated in this embodiment.

The method for updating the tracking area code provided in this embodiment can further improve the update efficiency of the TAC by establishing a default information base and synchronously updating the default information base.

2 is a schematic flowchart of a method for updating a tracking area code according to another embodiment of the present invention;

As shown in FIG. 2, on the basis of the above embodiment, in the method for updating the tracking area code provided by another embodiment of the present invention, after receiving the city area code corresponding to the third calling and called TAC returned by the system maintenance platform , the method also includes:

Step 16: If it is judged that the city area code corresponding to the TAC of the third calling party is not the default city area code, send a misjudgment message to the charging application server AS to notify the charging AS to correct the corresponding city area code of the TAC of the third calling party. Call records generated by the call record.

For the SBC, the TAC of the third caller is a newly added TAC, and the default city area code is specified by the SBC by default. There may also be two situations:

1. The newly added TAC is also the TAC of the default city, that is, the actual call is also made in the default city. Second, the newly added TAC is not the TAC of the default city, and the actual call is not in the default city.

The TAC of the third calling party is a newly added TAC of the LTE network, and there may be problems in the roaming judgment of the call record.

Since the TAC of the third calling party is unfamiliar to the SBC and is a newly added TAC, the tracking area code updating device cannot determine whether the TAC of the third calling party belongs to the first or second situation above, and the system The maintenance platform verifies the TAC of the third caller.

If the city area code corresponding to the TAC of the third calling party is not the default city area code, it means that the third TAC is not configured in the SBC, and the tracking area code updating device sends a configuration message to the maintenance department of the SBC, and configures the TAC and the SBC on the SBC. Corresponding to the city area code, the tracking area code updating device also sends a misjudgment message to the billing AS to notify the billing AS to correct the wrong call bill generated by the call record in time.

The AS (Application Server, application server) in the IMS domain is responsible for providing basic services and supplementary services of VoLTE multimedia telephony, and at the same time, performs charging control and production of charging information for VoLTE calls.

If the city area code corresponding to the calling TAC happens to be the TAC of the default city, the system maintenance personnel will return the TAC and the corresponding city area code for the tracking area code update device to send a configuration message to the maintenance department of the SBC, and configure the configuration on the SBC. The TAC and the corresponding city area code ensure that the default information base is updated correctly.

In the prior art, the error in specifying the default city area code of the SBC will also cause the IMS network to misjudge the roaming location displayed in the CDR and miscalculate the roaming charge. After the user discovers the wrong billing and receives the user's complaint, the call fee is reduced or exempted for the user, and then the corresponding TAC corresponding table is updated as soon as possible, but this method can only be used for post-event remedy. The problem of misbilling.

Other steps in this embodiment are similar to those in the foregoing embodiment, and are not repeated in this embodiment.

The method for updating the tracking area code provided by this embodiment analyzes the call records closely related to the CDR. After determining that there is a problem with the call record, the problem caused by the configuration error is discovered in real time, and the problem is dealt with before the user complains. , timely adjust call charges and bill display problems, and can notify maintenance personnel to update the data configuration table immediately, thereby improving maintenance efficiency and avoiding user complaints.

In order to more fully understand the technical content of the present invention, the method for updating the tracking area code provided in this embodiment is described in detail on the basis of the above-mentioned embodiment.

According to the prior art, the occurrence of such problems can only be reduced by checking the data configuration table regularly. However, due to the frequent occurrence of network changes, the periodic configuration checking cannot avoid such problems in time.

The method proposed by the embodiment of the present invention can discover problems caused by configuration errors in real time, handle problems prior to user complaints, adjust call charges and bill display problems in time, and notify maintenance personnel to immediately update the data configuration table, thereby improving maintenance efficiency. Avoid user complaints.

FIG. 3 shows a principle flowchart of a method for updating a tracking area code provided by another embodiment of the present invention.

As shown in Figure 3, the specific description is as follows:

Step S101: Using the default area code configured on the SBC as an index, build an information base 1, that is, the aforementioned default information base.

Using the default area code configured on the SBC, such as 0371, as an index, manually create an information base corresponding to the default TAC and the default city area code (eg, 0371). After the establishment of the information database is completed, check the accuracy with the wireless department one by one to ensure that the information is accurate.

Step 102: Establish an information base 2, that is, the aforementioned call record information base.

Optionally, take the existing network VoLTE call records as basic data, retrieve and generate relevant records containing default area code information and write into information base 2.

Based on the big data in the VoLTE signaling monitoring system, a call record is extracted from the user call signaling record. If the city area code corresponding to the TAC of the call record contains the default city area code, the record will be saved, and this record will be saved. The information such as the numbers of both parties to the call, the call time and other information corresponding to the record are stored in the information base 2 .

Step 103: Extract the TAC information from the information base 2, and check whether the TAC information is in the information base 1.

Step S104: If it is in the information base 1, it means that the TAC has been correctly configured, and the system automatically deletes the record from the information base 2.

Step S105: If the TAC information is not in the information base 1, it is judged that the TAC is a newly added TAC on the existing network, and the system issues an alarm, and the alarm information contains all the contents of the record in the information base 2, so that the system maintenance personnel The information fed back by the department confirms whether the new TAC is the TAC newly added by the default city.

Step S106: After the system maintenance personnel verify the TAC information with the wireless personnel according to the alarm information, if the TAC is not the TAC corresponding to the default city, it means that the TAC information has not been configured, and the system maintenance personnel immediately notify the SBC maintenance department to configure the TAC on the network element. TAC and the area code information of the corresponding city, notify the billing department to correct the wrong billing record generated under the TAC in time.

Step S107: If the TAC is the TAC corresponding to the default city, the system maintenance personnel need to add a record of the TAC and the default city area code to the information base 1 to ensure that the records of the information base 1 are correctly updated.

The method for updating the tracking area code provided by this embodiment has at least the following technical effects:

To determine whether the TAC generated in the actual call is a newly added TAC, it can quickly and efficiently discover and solve the problems existing in the existing network without the need for network transformation or investment of hardware resources.
