Description

Updating method, system, electronic device and storage medium of tracking area code

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a method and a system for updating a tracking area code, electronic equipment and a storage medium.

Background

VoLTE (Voice over Long Term Evolution) is a Long Term Evolution (Long Term Evolution) Voice solution for LTE based on IMS (IP multimedia Subsystem) networks.

When a VoLTE user makes a call, the IMS network needs to have the function of judging the city where the VoLTE user is located when the VoLTE user makes a call, and further provides a basis for the follow-up work of whether the user roams, roaming charging, roaming bill presentation and the like. This function is performed by a SBC (Session Border Controller) according to the specification.

The specific principle of the SBC for determining the city where the VoLTE user is located during the call is as follows:

when receiving a call initiated by a VoLTE user, the SBC actively sends a signaling requesting location information to the LTE network, the LTE network finally returns the current TAC (Tracking Area Code) information of the user to the SBC, and the SBC maps an urban Area Code corresponding to the TAC according to the TAC and a TAC configuration table configured by a network element of the SBC (the TAC configuration table includes a corresponding relationship between each TAC and the urban Area Code), and sends the urban Area Code to a subsequent network element of the IMS network for reference use through the signaling, so as to charge the user.

In the process of using the above functions, the most critical ring is the accuracy of the table of the correspondence between the TAC and the city area code in the SBC network element, and in the prior art, the table is configured manually, and the SBC maintenance manager is notified manually to update the configuration table according to the configuration when the TAC of the LTE network is adjusted or newly added by a branch company or a wireless department. In practical application, the TAC information on the SBC network element is often inaccurate in the existing network due to frequent network changes and post changes of branch companies, wireless departments and SBC maintenance and management personnel.

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 omits to configure the newly added TAC and the corresponding city area code relationship, the SBC will correspond the newly added TAC to a default city area code (generally, a provincial city, for example, zheng city area code 0371), determine whether the call is roaming according to the default city area code, and use the default city area code as the charging basis for the subsequent VoLTE call.

It can be understood that the newly added TAC may be just the city area code of zheng state, or may not correspond to the city area code of zheng state, but correspond to other places in the south of the river, such as luoyang, if the VoLTE call in luoyang occurs, the TAC of the calling ticket is wrongly corresponding to the city area code of 0371, the zheng state roaming information is displayed on the subsequent ticket, and the charging is performed according to the zheng state roaming.

It can be seen that, when the LTE network adjusts the TAC or adds the TAC newly, the IMS network is not notified in time to modify the corresponding TAC, so that the SBC defaults to assign a corresponding city area code for the newly added TAC, and the default city area code is not an area code of a city where the user actually calls, and the newly added TAC is mistakenly corresponded to the default city area code.

The prior art solution is to periodically update the TAC table to reduce the probability of adding new TAC to the SBC.

It can be understood that this solution is very difficult to implement, the TAC on the network side changes very frequently, the process of checking the corresponding table of the TAC every time is complex, not to mention checking at high frequency, and the labor and time costs are high, so that the change of the TAC may not be found in time in practical application.

At present, the prior art has no corresponding method for solving the problems.

Detailed Description

In order to make the objects, 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, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

The terminology of the embodiments of the present invention is explained:

VoLTE is an IP data transmission technology, a 2G/3G network is not needed, all services are borne on a 4G network, and the unification of data and voice services in the same network can be realized.

The tracking Area corresponding to tac (tracking Area code) is an Area for paging and location update, and is similar to the concept of LAC (location Area code) in UMTS (Universal Mobile Telecommunications System) network. The TAC may uniquely identify an area, and the area corresponding to one TAC may include one or more cells.

The IMS is a new multimedia service format, can meet the requirements of the current terminal client for more novel and diversified multimedia services, and is a core network control architecture of the VoLTE service.

The SBC is located at the edge of the IMS core network, and is a first node of the VOLTE network to which the terminal accesses, and the SBC serves as a signaling proxy and a media proxy of the IMS core network, and mainly aims to isolate an access network and the IMS core network, and implement functions of NAT (network address Translation) traversal, firewall traversal, QOS (Quality of Service) control, network security, TAC-to-city area code mapping, and the like.

Fig. 1 is a flowchart illustrating a method for updating a tracking area code according to an embodiment of the present invention.

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

step 11, obtaining a call record of a preset time period, where the call record includes a tracking area code TAC of a first caller and an urban area code corresponding to the TAC of the first caller, where the TAC of the first caller is a TAC received by a session edge controller SBC and sent by an LTE network, and the urban area code is obtained by the SBC according to the TAC of the first caller and a correspondence between the TAC and the urban area code stored in the SBC;

the updating device of the tracking area code in the embodiment of the invention is an optimized platform of an IMS network, is a third-party server with an independent processing function, and is applied to the embodiment of the invention to realize the checking and updating of TAC.

Optionally, the extracted call record is a call record of calls that have been connected, including ongoing calls, and completed calls. The call log can describe the call connection process in detail, and comprises the following steps: call type (e.g., charge for answer, free for answer, failure, timeout, etc.), start time, answer time, talk time, caller number, TAC of caller, and corresponding city area code, etc.

Optionally, the LTE network sends a VoLTE call of the user to the IMS network, the SBC requests location information from the LTE network when receiving the call initiated by the user, the SBC receives the TAC of the caller, maps an urban area code corresponding to the TAC of the caller according to the received TAC of the caller and the first correspondence, and determines whether the user roams according to the urban area code. And the subsequent signaling monitoring system extracts the TAC and the city area code of the calling party from the SBC to generate the call record, and the server acquires the call record in a preset time period from the signaling monitoring system.

Optionally, the signaling monitoring system is configured to monitor signaling in a network, and the whole system includes three modules, i.e., an acquisition module, a processing module, and an analysis module. The acquisition module receives original data from the VoLTE network, tracks various signaling messages in the same calling process, acquires service information from the messages and analyzes the service information to form a user call signaling record. The processing module generates a pre-statistical table according to the call signaling record of the user, monitors and writes the pre-statistical table into a database, and the analysis module provides data query and analysis service.

Step 12, determining a TAC of a second calling party, wherein the TAC of the second calling party is the TAC of the first calling party, the city area number of which is matched with a default city area number, the default city area number is the designated city area number of which is defaulted by the SBC according to a newly added TAC, and the newly added TAC is a TAC other than the TAC stored in the SBC;

optionally, when the TAC received by the SBC is an unknown and newly added TAC, 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 area code of the city where the default user is located is the default city area code.

Optionally, the updating apparatus for tracking area codes filters the TAC of the first caller, and filters the TAC of the first caller whose city area code is the default city area code, and it can be understood that, if the city area code corresponding to the TAC of the caller is the default city area code of the SBC, the call record also judges whether roaming occurs according to the default city area code, and the call record may have a roaming judgment error.

There may be two situations for the call log: for the SBC, the TAC of the second calling party is the TAC stored by the SBC, the area code of the default city is obtained by the SBC according to the storage mapping, namely the actual call really corresponds to the area code of the default city, and for the SBC, the TAC of the second calling party is a newly added TAC, and the area code of the default city is specified by the SBC.

Optionally, in the first case, the updating device for tracking area code does not need to do processing, and in the second case, the updating device equivalent to tracking area code finds new TAC according to the call record.

Step 13, determining a TAC of a third calling party, wherein the TAC of the third calling party is the TAC of a second calling party which is not matched with a default TAC, and the default TAC is the TAC corresponding to the default city area code;

optionally, a further screening is performed on the TAC of the second caller to clarify which case the reason considered as the default city area code belongs to.

Optionally, the updating device for tracking area codes matches the default TAC according to the TAC of the second caller, and if the TAC of the second caller is the default TAC, it indicates that the call actually occurs in the default city area code, which belongs to the first case, and the TAC of the first caller in the call record is already configured correctly.

If the TAC of the second caller is not any default TAC, it indicates that the TAC of the second caller is a newly added TAC of the LTE network for the SBC, which belongs to the second case, and the city area code determined by the SBC in step 11 may be wrong, and the city area code in the call record may be wrong.

Optionally, TAC of the second caller meeting the condition is screened out as TAC of the third caller.

Step 14, sending alarm information, wherein the alarm information comprises the TAC of the third calling party, so that a system maintenance platform can determine the city area code corresponding to the TAC of the third calling party;

in the embodiment of the invention, the SBC carries out roaming judgment on the calling TAC according to the first corresponding relation between the TAC and the city area code stored in the SBC, and generates the call ticket corresponding to the call record so as to charge the call ticket and display the place where the call ticket occurs. Since the TAC of the third caller is an unknown and newly added TAC to the SBC, neither the SBC nor the update device tracking the area code stores the city area code corresponding to the TAC of the third caller, and needs to be determined by the system maintenance platform.

Optionally, the system maintenance platform is an updating device for maintaining a tracking area code updated by the TAC in the LTE network, stores the latest TAC corresponding table, receives the TAC of the third calling party, obtains an urban area code corresponding to the TAC of the third calling party, and returns the urban area code to the updating device for tracking area code.

And step 15, receiving the city area code corresponding to the third calling and called TAC returned by the system maintenance platform, and sending the city area code to the SBC, so that the SBC can add the third calling and called TAC and the corresponding city area code in the first corresponding relation.

In the embodiment of the invention, the TAC corresponding table of the SBC is not limited to high-frequency updating, but the method concentrates on practical application scenes, aiming at each actually generated call record, the TAC of the second calling party, the city area number of which is corresponding to the TAC of the first calling party of the call record is the default city area number, the call record which is possibly subjected to roaming misjudgment is screened out, the reason that the TAC of the second calling party is the default city area number is further judged, when the TAC of the second calling party is a newly-added TAC and is designated as the default city area number, alarm information is sent out, system maintenance personnel check the TAC of the third calling party in a targeted manner, and the newly-added TAC is updated and maintained.

It can be understood that, because the roaming misjudgment problem is closely related to the call records, each call record which may have roaming misjudgment is directly processed and analyzed, and the problem caused by the SBC assignment error is found in a targeted and real-time manner, compared with the simple updating of the TAC corresponding table of the SBC, the maintenance efficiency is greatly improved.

The following examples illustrate embodiments of the invention:

when the Henan SBC receives the newly added TAC returned by the LTE network, the area code 0371 of Zheng state is directly appointed to be used as the location of the VoLTE user, then the 0371 is the default city area code, the TACs corresponding to the 0371 stored on the Henan SBC are obtained, and the TACs corresponding to Zheng state stored on the current Henan SBC are called default TACs.

The updating device for tracking the area code acquires the call record in Henan, extracts the TAC of the calling party, acquires the corresponding relation between the TAC and the city area code stored in advance by the SBC, simulates the city area code corresponding to the TAC of the calling party on the SBC, and can predict the city area code corresponding to the call record.

If the calling TAC in the call record corresponds to zheng, there may be two situations: one, indeed zheng, and two, are designated by default as zheng.

And aiming at each corresponding TAC of the calling party in Zheng state, determining whether the TAC of the calling party is matched with the default TAC according to the pre-established corresponding relation between the default TAC and the default city area code: if the call records are matched with the call records, the call records belong to the condition I, and the call records corresponding to the call records have no problem; and if not, sending alarm information to allow the system maintenance platform to determine the corresponding city area code of the calling TAC, and newly adding the calling TAC and the corresponding city area code.

In the updating method of the tracking area code provided by this embodiment, the city area code corresponding to the first calling TAC of the call record is screened to obtain the second calling TAC which may have roaming misjudgment, and it is further determined whether the second calling TAC is the newly added TAC, if so, the second calling TAC is added to the first corresponding relationship of the SBC, and the newly added TAC can be updated in time and efficiently.

As shown in fig. 1, on the basis of the foregoing embodiment, in the method for updating a tracking area code according to another embodiment of the present invention, after determining the TAC of the second caller, the method further includes:

and establishing a call record information base, wherein the call record information base comprises a call record corresponding to the TAC of the second calling party.

Optionally, the TAC of the second calling party is the TAC of the first calling party whose city area code is matched with the default city area code, and the problem of roaming misjudgment may exist, and the call record which is possibly misjudged by roaming is stored in the call record information base, so that the call record which is possibly misjudged by roaming is further screened in the following process.

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

and deleting the call record corresponding to the TAC of the second calling party matched with the default TAC in the call record information base.

It can be understood that, by maintaining the call record information base in real time, the memory can be released in time, and the updating device for tracking the area code can read the call record of the call record information base in real time.

Other steps of this embodiment are similar to those of the previous embodiment, and are not described again in this embodiment.

In the updating method of the tracking area code provided by this embodiment, the call records that may be misjudged by roaming are stored in the call record information base by establishing the call record information base, which is beneficial to performing further remedial measures on each call record that may be misjudged by roaming.

As shown in fig. 1, on the basis of the foregoing embodiment, in the method for updating a tracking area code according to another embodiment of the present invention, before determining the TAC of the third caller, the method further includes:

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

and checking the accuracy of the default information base according to a pre-acquired TAC update table.

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

Optionally, when the TAC received by the SBC and returned by the LTE network is a newly added TAC and the area code of the city of the newly added TAC is not stored, directly assigning an area code of the city to the newly added TAC, that is, the area code of the city where the default user is located is the assigned area code of the city, and the area code of the city is referred to as the default area code of the city.

Optionally, after the update apparatus for tracking area codes acquires the default city area code, the default TAC stored on the SBC corresponding to the default city area code is acquired with the default city area code as an index.

Optionally, the default TAC is a TAC corresponding to a default city area code stored in the current SBC, and an area corresponding to the default TAC is actually within a city range corresponding to the default city area code. There are multiple default TACs for one default city area code.

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

Optionally, after the default information base is established, the accuracy of the default TAC is checked item by item with a TAC update table stored in a wireless department of the LTE network, so as to ensure that the default TAC really corresponds to the default city area code, thereby ensuring that the information is accurate.

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

and adding the TAC of the third calling party and the third called party and the corresponding city area code in the default information base.

Optionally, after the checking of the default information base is completed, although the accuracy checking has been performed, it can only be ensured that the default information base is accurate within a period of time, because the checking process is complex and the TAC changes very frequently, it is impossible to ensure that the default information base is always accurate in practical application, and there may be a case that the configuration of the newly added TAC default information base is omitted.

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

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

as shown in fig. 2, on the basis of the foregoing embodiment, in the method for updating tracking area code according to 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 further includes:

and step 16, if the fact that the city area code corresponding to the TAC of the third calling party is not the default city area code is judged and obtained, sending a misjudgment message to a charging Application Server (AS) to inform the charging AS to correct a call bill generated by the call record corresponding to the TAC of the third calling party.

For the SBC, the TAC of the third caller is the newly added TAC, and the default city area code is specified by the SBC by default, and there may be two cases:

the newly added TAC is also the TAC of the default city, namely the actual call also occurs in the default city, the newly added TAC is not the TAC of the default city, and the actual call generation place is not in the default city.

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

Since the TAC of the third caller is a new TAC that is strange to the SBC, the updating apparatus for tracking the area code cannot determine whether the TAC of the third caller belongs to the first case or the second case, and the TAC of the third caller is verified by the system maintenance platform.

If the city area number corresponding to the TAC of the third calling party is not the default city area number, the third TAC is configured in the SBC in a missing way, the updating device for tracking the area code sends a configuration message to a maintenance department of the SBC, the TAC and the corresponding city area number are configured on the SBC, and the updating device for tracking the area code also sends an erroneous judgment message to the charging AS so AS to inform the charging AS to correct an error bill generated by the call record in time, wherein the correction comprises the correction of the call charge and the call generation place.

An Application Server (AS) in the IMS domain is responsible for providing the basic service and supplementary service of the VoLTE multimedia telephone, and performing charging control and charging information generation for the VoLTE call.

If the city area code corresponding to the calling TAC is just the TAC of the default city, the system maintainer returns the TAC and the corresponding city area code so that the updating device for tracking the area code sends a configuration message to the maintenance department of the SBC, and configures the TAC and the corresponding city area code on the SBC to ensure that the default information base is updated correctly.

In the prior art, an error in the SBC specifying the default city area code will also cause the IMS network to misjudge the roaming place displayed in the ticket, and miscalculate the roaming fee. When a user finds out the error charging and receives the complaint of the user, the telephone charge is saved for the user, and then the corresponding TAC corresponding table is updated as soon as possible.

According to the updating method of the tracking area code, the call records closely related to the call ticket are analyzed, the problem caused by configuration error is found in real time after the call records are determined to have problems, problem processing is performed before the complaint of the user, the problems of call charges and call ticket display are adjusted in time, and the maintenance personnel can be informed to update the data configuration table immediately, so that the maintenance efficiency is improved, and the complaint of the user is avoided.

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

The problem can be reduced only by checking a data configuration table periodically in the prior art, but the problem cannot be avoided timely by checking the periodic configuration because the network changes constantly.

The method provided by the embodiment of the invention can find the problem caused by the configuration error in real time, process the problem before the user complaints, adjust the call charge and the call ticket display problem in time, and inform the maintenance personnel to update the data configuration table immediately, thereby improving the maintenance efficiency and avoiding the user complaints.

Fig. 3 is a schematic flow chart illustrating an updating method of tracking area codes according to another embodiment of the present invention.

As shown in fig. 3, the following is specifically explained:

step S101: the default area code configured on the SBC is used as an index to establish the information base 1, i.e. the aforementioned default information base.

An information base of the default TAC corresponding to the default city area code (e.g. 0371) is manually established by using the default area code (e.g. 0371) configured on the SBC as an index. After the information base is established, the information base is checked with the wireless department one by one to ensure the accuracy of the information.

Step 102: an information base 2, namely the call record information base is established.

Optionally, based on the VoLTE call record of the current network, a relevant record containing the default area code information is retrieved and generated and written into the information base 2.

Based on big data in a VoLTE signaling monitoring system, a call record is extracted from a user call signaling record, if the city area code corresponding to the TAC of the call record contains a default city area code, the record is stored, and the record and information such as the numbers of calling parties and the calling time corresponding to the record are stored in the information base 2.

Step 103: TAC information is extracted from the information base 2, and it is checked whether the TAC information is in the information base 1.

Step S104: if in the repository 1, indicating that the TAC is configured correctly, the system automatically deletes the record from the repository 2.

Step S105: if the TAC information is not in the information base 1, the TAC is judged to be a newly added TAC of the current network, the system sends out an alarm, and the alarm information contains all the contents of the record in the information base 2, so that system maintenance personnel can confirm whether the new TAC is a newly added TAC of a default city according to the information fed back by the wireless department.

Step S106: after the system maintenance personnel verify the TAC information according to the warning information and the wireless personnel, if the TAC is not the TAC corresponding to the default city, the TAC information is indicated to be configured neglectedly, the system maintenance personnel immediately inform an SBC maintenance department of configuring the TAC and the area code information of the corresponding city on a network element, and inform a charging department of timely correcting the wrong charging record generated under the TAC.

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 area code of the default city to the information base 1, so as to ensure that the record of the information base 1 is correctly updated.

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

and judging whether the TAC generated in the actual call is a newly added TAC or not, and quickly and efficiently discovering and solving the problems of the existing network without network modification and hardware resource investment.

Optionally, the roaming determination of the call record is determined according to the city area code mapped by the SBC, and here, according to the TAC of the first caller and the first corresponding relationship, the city area code corresponding to the TAC of the caller on the SBC may be simulated.

Optionally, the first determining module 42 filters the TAC of the first caller, and filters the TAC of the first caller whose city area code is the default city area code, and it can be understood that, if the city area code corresponding to the TAC of the caller is the default city area code of the SBC, the call record also judges whether roaming occurs according to the default city area code, and the call record may have a roaming judgment error.

Alternatively, for the first case, the first determining module 42 does not need to do processing, and for the second case, the updating device equivalent to the tracking area code finds the new TAC according to the call record.

Optionally, the second determining module 43 further filters the TAC of the second caller to determine which of the above cases the reason is considered as the default city area code.

Optionally, the second determining module 43 matches the default TAC according to the TAC of the second caller, and if the TAC of the second caller is the default TAC, it indicates that the call actually occurs in the default city area code, which belongs to the first case, and the TAC of the first caller in the call record is already configured correctly.

If the TAC of the second caller is not any default TAC, it indicates that the TAC of the second caller is a newly added TAC of the LTE network for the SBC, which belongs to the second case, and the city area code determined in step 12 may be wrong.

In the embodiment of the invention, the SBC carries out roaming judgment on the calling TAC according to the first corresponding relation between the TAC and the city area code stored in the SBC, and generates the call ticket corresponding to the call record so as to charge the call ticket and display the place where the call ticket occurs. Since the TAC of the third caller is an unknown and newly added TAC to the SBC, the SBC needs to be determined by the system maintenance platform no matter the SBC does not store the city area code corresponding to the TAC of the third caller.

Optionally, the system maintenance platform is an updating device for maintaining tracking area codes updated by the TAC in the LTE network, stores the latest TAC corresponding table, receives the TAC of the third calling party, obtains an urban area code corresponding to the TAC of the third calling party, and returns the urban area code to the second sending module 45.

The device further comprises a first establishing module for establishing a call record information base, wherein the call record information base comprises a call record corresponding to the TAC of the second calling party.

The first establishing module is further configured to delete the call record corresponding to the TAC of the second caller, which is matched with the default TAC, in the call record information base.

The device also comprises a second establishing module for establishing a default information base, wherein the default information base comprises the default TAC corresponding to the default city area code; and checking the accuracy of the default information base according to a pre-acquired TAC update table.

The device also comprises a second establishing module which is also used for adding the TAC of the third calling and called party and the corresponding city area code in the default information base.

The device also comprises a correction module used for sending a misjudgment message to a charging Application Server (AS) if the fact that the city area code corresponding to the TAC of the third calling party is not the default city area code is judged and obtained, so AS to inform the charging AS to correct the call ticket generated by the call record corresponding to the TAC of the third calling party.

The acquisition module is further used for acquiring the call record from a signaling monitoring system.
