[0022] In conjunction with the accompanying drawings, a number location information storage method, system, device and medium provided by the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0023] First, refer to Figure 1 FIG. 1 is a flowchart of a method for storing number location information provided by an embodiment of the present application. The method may include the following steps: Step S11: Obtain the current number location information from the core network, the number location information including: user number, location information of the base station cell associated with the user number, and Internet Protocol IP address and domain name information of the service session control function S-CSCF network element associated with the user number.

[0024] The location information of the base station cell may include a tracking area code (Tracking Area Code, TAC), a base station identifier (EnobID), a cell identity (Cell Identity, CI), and the like.

[0025] In specific implementation, a real-time data channel can be pre-established or an existing real-time data channel can be reused to obtain the user number, the location information of the base station cell associated with the user number, and the Internet Protocol (IP) address and domain name information of the S-CSCF network element associated with the user number and other number location information in real time (or periodically) from the relevant network elements in the core network.

[0026] Step S12: using the user number contained in each piece of number location information as a key, and using other information contained in each piece of number location information as a value, to generate first key-value pair data associated with each piece of user number.

[0027] In the specific implementation, for each number location information, the user number contained in the number location information is used as the Key, and the other information contained in the number location information (i.e., the location information of the base station cell, the IP address and domain name information of the S-CSCF network element stationed in the network) is used as the Value, thereby adopting the Key-Value data structure to generate positive key-value pair data (i.e., the first key-value pair data).

[0028] It can be understood that the forward key-value pair data, by using the user number as the key, can support accurate and fast query of the number location information associated with a single user number, thereby providing timely and effective data support for business scenarios such as high-throughput emergency SMS delivery and emergency voice services for designated numbers.

[0029] Step S13: For the location information of each base station cell contained in the respective number location information, the location information of the base station cell is used as the key, and other information contained in the different number location information associated with the location information of the base station cell is used as the value to generate second key-value pair data associated with the location information of the base station cell.

[0030] In specific implementation, the number location information may be grouped first according to whether the location information of the included base station cells is the same. Then, for each base station cell location information, the base station cell location information is used as the key, and other information (i.e., the user number, the IP address and domain name information of the S-CSCF network element stationed in the network) included in each number location information in the group corresponding to the base station cell location information is used as the value, thereby using the Key-Value data structure to generate reverse key-value pair data (i.e., the second key-value pair data).

[0031] It can be understood that the reverse key-value pair data can support batch and fast query of number location information associated with multiple user numbers by using the location information of the base station cell as the key, that is, it can support batch query of number location information associated with multiple terminals in the base station cell, thereby providing timely and effective data support for business scenarios such as high-throughput emergency SMS sending and emergency voice services in a specified area (such as one or more base station cells).

[0032] Step S14: storing each of the first key-value pair data and each of the second key-value pair data in a memory based on a distributed cache technology.

[0033] In specific implementation, a storage cluster including multiple storage nodes (which may be multiple virtual machines or servers) may be established in advance at the edge of the network, and then each of the first key-value pair data and each of the second key-value pair data may be sent to the multiple storage nodes respectively, so that the multiple storage nodes store the received data in their corresponding memory (such as a memory database), thereby storing the number location information in the memory based on the distributed cache technology.

[0034] It can be understood that the number location information is organized into the form of keys and values, and stored in the memory using distributed caching technology. The storage process of the number location information is optimized from multiple aspects such as data structure, data storage method and storage location, so that the system can quickly process high-concurrency query requests, thereby meeting large-scale number location query needs (such as the location information query needs of more than 10,000 downlink numbers per second).

[0035] Optionally, the method further includes: persistently storing the data stored in the memory according to a set period, for example, persistently storing the data in the memory of the storage node to a local disk every hour to prevent the data in the memory from being lost due to a node restart.

[0036] By adopting the technical solution of the embodiment of the present application, the number location information is organized and stored in the form of key-value pairs, and the user number is used as the key to generate the forward key-value pair data (i.e., the first key-value pair data), and the location information of the base station cell is used as the key to generate the reverse key-value pair data (i.e., the second key-value pair data). Based on the forward and reverse key-value pair data storage method, it is possible to meet the one-to-one number location information query demand (i.e., the query demand for accurately querying the number location information of a single user number) while taking into account the one-to-many number location information query demand (i.e., the query demand for batch querying the number location information of multiple user numbers), and based on the distributed cache technology, the first key-value pair data and the second key-value pair data are stored in the memory, which can further improve the data query efficiency. In this way, it is possible to meet the large-scale number location query demand and provide timely and effective data support for business scenarios such as high-throughput emergency SMS delivery and emergency voice services.

[0037] As a possible implementation manner, the number location information further includes registration time; and the method further includes: Step S21: for the first user number associated with the first key-value pair data stored in the memory, obtain the latest number location information associated with the first user number from the core network, and detect whether there is a location change of the first user number.

[0038] In specific implementation, the number location information including the first user number can be extracted from the currently acquired number location information according to the first user number, the extracted number location information is used as the latest number location information associated with the first user number, and whether the first user number has a location change is detected.

[0039] For example, it may be detected whether relevant signaling indicating that the first user number has a location change is received from the core network (for example, the core network may be configured to indicate the location change of the user number once every fifty minutes). Alternatively, the latest number location information associated with the first user number may be compared with the first key-value pair data associated with the first user number to determine whether there is a difference between the location information of the base station cell associated with the first user number and the IP address and domain name information of the S-CSCF network element in the two aforementioned data. If there is a difference, it means that the first user number has a location change, and if there is no difference, it means that the first user number has no location change.

[0040] Step S22: when there is no location change of the first user number, the registration time in the latest number location information is used to update the registration time in the first key-value pair data associated with the first user number in the memory.

[0041] In a specific implementation, if there is no location change of the first user number, only the registration time contained in the first key-value pair data associated with the first user number in the memory may be updated to ensure the correctness of the registration time recorded in the first key-value pair data.

[0042] Step S23: when the location of the first user number changes, the value corresponding to the first key-value pair data associated with the first user number is updated in the memory using other information in the latest number location information except the first user number.

[0043] In a specific implementation, if the location of the first user number changes, the value (Value) corresponding to the first key-value pair data associated with the first user number is updated in the memory, that is, the registration time, the location information of the base station cell, and the IP address and domain name information of the S-CSCF network element contained in the first key-value pair data are updated to ensure the correctness of the number location information recorded in the first key-value pair data.

[0044] Step S24: updating the second key-value pair data stored in the memory according to the updated first key-value pair data.

[0045] In a specific implementation, the number location information associated with the first user number recorded in the relevant second key-value pair data can be updated according to the updated first key-value pair data; or, the second key-value pair data can be regenerated for the location information of the base station cell associated with the updated first key-value pair data, and the regenerated second key-value pair data can be used to overwrite the relevant second key-value pair data stored in the memory, so as to update the second key-value pair data stored in the memory. In this way, the correctness of each number location information recorded in the second key-value pair data can be guaranteed.

[0046] In this implementation, the present application ensures the timeliness of the data stored in the memory by detecting whether there is a location change of the user number, and then updating the relevant first key-value pair data and second key-value pair data; and because the first key-value pair data uses the user number as the key, it is possible to quickly query and update the first key-value pair data associated with a specific user number; and then retrieve and update the relevant second key-value pair data based on the updated first key-value pair data, thereby achieving timely update of the number location information recorded in the memory (such as the network element information of the user number), so as to better adapt to actual communication scenarios where location information is frequently updated, and meet the requirements of high real-time and high accuracy of number location information in emergency message sending scenarios related to disaster recovery and rescue.

[0047] Optionally, the step S24 includes: Step S241: Acquire location information of a first base station cell associated with the first user number from the updated first key-value pair data; Step S242: using other information in the updated first key-value pair data except the location information of the first base station cell, updating the value corresponding to the second key-value pair data associated with the location information of the first base station cell in the memory.

[0048] In specific implementation, in order to further improve the updating efficiency, the location information of the first base station cell can be used as a key to quickly retrieve the relevant second key-value pair data. Then, other information (i.e., user number, registration time, and IP address and domain name information of the S-CSCF network element) in the updated first key-value pair data except the location information of the first base station cell is added to the value corresponding to the second key-value pair data, thereby updating the second key-value pair data stored in the memory. Optionally, the validity of the data stored in the memory can also be regularly judged according to the registration time, and invalid data can be cleared.

[0049] As a possible implementation, the method further includes: Step S31: receiving a query request through a pre-configured application programming interface API.

[0050] In specific implementation, an API can be configured to uniformly receive query requests from external devices; alternatively, different APIs can be configured for different types of query requests. For example, query requests carrying user numbers (precise queries of corresponding number location information) and query requests carrying base station cell location information (batch queries of corresponding number location information) can be received using different APIs, thereby avoiding the classification process of query requests and improving the processing efficiency of query requests.

[0051] Step S32: In the case where the query request carries a second user number, obtain the first key-value pair data associated with the second user number from the memory, generate and return a first query result based on the obtained first key-value pair data, wherein the first query result is used to send a message to the terminal associated with the second user number, and the first query result includes: the location information of the base station cell associated with the second user number and the domain name information of the S-CSCF network element.

[0052] In the specific implementation, the second user number is used as the key (Key), and the GET function is used to quickly obtain the value (Value) corresponding to the second user number from each first key-value pair data stored in the memory, and then the location information of the base station cell and the domain name information of the S-CSCF network element are extracted from the obtained value, and the extracted information is returned as the first query result to support related external devices to send messages to the second number, such as using the second number to send emergency text messages or voice messages to the corresponding terminal, and to connect emergency calls based on the S-CSCF network element attached to the second number.

[0053] Step S33: In the case where the query request carries the location information of the second base station cell, obtain the second key-value pair data associated with the location information of the second base station cell from the memory, and generate and return the second query result based on the obtained second key-value pair data, wherein the second query result is used to send messages to each terminal associated with the base station cell, and the second query result includes: multiple user numbers in the base station cell associated with the location information of the second base station cell, and domain name information of the S-CSCF network element associated with each of the multiple user numbers.

[0054] In the specific implementation, the location information of the second base station cell is used as the key (Key), and the GET function is used to quickly obtain the value (Value) corresponding to the location information of the second base station cell from each second key-value pair data stored in the memory, and then multiple user numbers and domain name information of the S-CSCF network elements associated with each of the multiple user numbers are extracted from the obtained values, and the extracted information is returned as the second query result to support related external devices to send messages to the specified area, such as using each user number in the second base station cell to send emergency text messages or voice messages to the corresponding terminal, and making emergency call connections based on the S-CSCF network elements attached to each user number.

[0055] As a possible implementation manner, after obtaining the location information of each number at the current moment from the core network, the method further includes: Step S15: For each piece of number location information, determine a target hash value corresponding to the user number in the number location information based on a preset hash function, and replace the user number in the number location information with the target hash value.

[0056] In specific implementation, a preset hash function such as MD5 can be used to calculate the target hash value corresponding to the user number, thereby converting the user number into an information form that is not easily recognizable. By replacing the user number with the target hash value in the number location information, the user number can be prevented from being leaked in the subsequent data processing and storage stages, thereby protecting the user's privacy.

[0057] After obtaining the target hash value corresponding to each user number, the above step S14 can be implemented by the following step S16: Step S16: According to the target hash value corresponding to each user number, each of the first key-value pair data and each of the second key-value pair data are stored in the memory of different storage nodes in the distributed cache cluster, wherein the different storage nodes are used to store data associated with different hash values.

[0058] In a specific implementation, different hash value intervals may be pre-configured for different storage nodes, and the different hash value intervals are used to distribute data associated with different user numbers more evenly to different storage nodes.

[0059] Specifically, for each user number, the storage node used to store the information of the user number in the relevant first key-value pair data and the second key-value pair data is determined according to the hash value interval to which the target hash value corresponding to the user number belongs. This implements the distributed cache of each of the first key-value pair data and each of the second key-value pair data, and ensures that the data associated with the same user number can be read and written by the same storage node, which is conducive to further improving the query efficiency.

[0060] In this implementation, it is considered that the hash value can ensure the uniqueness of the user number and increase its difference: even if two different user numbers look similar, their hash values ​​will be completely different; therefore, allocating storage nodes based on the hash value and using it as a key for data retrieval can avoid confusion of similar user numbers and further improve retrieval (i.e., query) efficiency, and can avoid the situation where the same storage node processes too many similar user numbers, thereby helping to achieve load balancing, avoiding the situation where some nodes are overloaded while other nodes are idle, thereby optimizing resource usage.

[0061] As a possible implementation manner, the obtaining the location information of each number at the current moment from the core network includes: Step S41: collecting registration signaling from the S-CSCF network element in the core network in real time through the first real-time data channel.

[0062] In specific implementation, a new real-time data channel may be created, or an existing real-time data channel may be reused, to achieve real-time data communication with the S-CSCF network element in the core network.

[0063] Step S42: acquiring various target information from various registration signalings currently collected, the target information including: user number, location information of a base station cell associated with the user number, and an IP address of an S-CSCF network element associated with the user number.

[0064] In specific implementation, the collected registration signaling is parsed to extract information related to voice and SMS services (ie, the target information) to reduce the volume of data involved in subsequent data processing and storage.

[0065] Step S43: Generate each domain name query request according to each target information, and send each domain name query request to the core network through the second real-time data channel.

[0066] In the specific implementation, a new real-time data channel can be created, or an existing real-time data channel can be reused to realize real-time data communication with relevant network elements with domain name query function in the core network, wherein the relevant network element can be a network element with telephone number mapping Domain Name System (enumDNS) function, which can return the domain name information of the relevant S-CSCF network element according to the user number.

[0067] Step S44: Determine the target information and the domain name information of the S-CSCF network elements returned by the core network in response to the domain name query requests as the number location information at the current moment.

[0068] In this implementation, different real-time data channels are used to collect and query large-scale flow data, which can realize real-time collection and analysis of massive signaling data, so as to obtain the latest target information and domain name information of the S-CSCF network element (i.e., number location information) in time to store and update the number location information. Compared with the periodic data collection and post-analysis based on minutes (such as every 5 minutes or every 15 minutes) or hours in the related technology, this application can greatly improve the timeliness of the stored number location information.

[0069] For example, refer to Figure 2The structural diagram of the number location information storage system shown in the figure takes the number location information storage system executing the number location information storage method provided in the present application as an example to illustrate the implementation process of the method.

[0070] Reference Figure 3 The schematic diagram of the number location information storage and query process shown in FIG. 1 includes the following steps: Step 1: The signaling monitoring system obtains the location information of each number at the current moment.

[0071] In this step, the signaling monitoring system in the number location information storage system collects the real-time call detail record (CDR) registration signaling call single flow (which includes the registration signaling from the user received by the S-CSCF network element) in the core network through the real-time data channel, and extracts the value of the specified field from the real-time CDR registration signaling call single flow to obtain various target information, thereby reducing the resource overhead for subsequent storage and calculation; wherein the target information includes: the calling number (i.e., the user number), the IP address of the S-CSCF network element for receiving the relevant registration signaling, and the location information of the base station cell to which the calling number belongs.

[0072] At the same time, the signaling monitoring system queries the domain name information of the relevant S-CSCF network element in the VoLTE network through the A interface of another real-time data channel based on the currently acquired target information, and uses the combination of the obtained target information and domain name information as the number location information.

[0073] Then, the signaling monitoring system sends the number location information to the southbound interface of the signaling sharing platform in the number location information storage system through the socket interface in real time. The signaling sharing platform can thereby realize real-time processing of the real-time stream of the number location information, thereby ensuring the real-time processing of the data.

[0074] Step 2: The signaling sharing platform converts the user number in the number location information into a target hash value based on MD5, so that the same number can be pushed to the same storage node in the storage cluster for processing.

[0075] In specific implementation, refer to Figure 4 As shown in the schematic diagram of hash distribution, the signaling sharing platform can distribute relevant data to storage nodes based on hash values, and the storage nodes then store the received data in their own memory database (i.e., number location storage KV library). Optionally, a storage node and its backup node can be deployed on a virtual machine, and each storage node and its backup node can ensure data consistency based on a message synchronization mechanism.

[0076] Step 3: The signaling sharing platform stores the forward number location information.

[0077] In this step, the signaling sharing platform uses the user number as the key, the location information of the base station cell associated with the user number, the IP address and domain name information of the S-CSCF network element stationed in the network as the value, and uses the Key-Value data structure to generate positive key-value pair data and send it to the relevant storage node for memory storage. The positive key-value pair data is shown in Table 1 below, and the schematic diagram of the memory database for storing positive key-value pair data is shown in Figure 5 shown.

[0078] Table 1 Example of positive key-value pair data

[0079] Step 4: The signaling sharing platform stores the reverse number location information.

[0080] In this step, the signaling sharing platform uses the location information of the base station cell as the key, the user number associated with the location information of the base station cell, the IP address and domain name information of the S-CSCF network element on the network as the value, and uses the Key-Value data structure to generate reverse key-value pair data and send it to the relevant storage node for memory storage. The reverse key-value pair data is shown in Table 2 below, and the schematic diagram of the memory database for storing reverse key-value pair data is shown in Table 2 below. Figure 6 shown.

[0081] Table 2 Example of positive key-value pair data

[0082] Among them, refer to Figure 7 The schematic diagram of data update when the number position has not changed is shown. After the real-time data is associated, if it is detected that the user number associated with the real-time data has not changed in position, the registration message time (ie, registration time) in the related forward and reverse key-value pair data is updated; refer to Figure 8 The schematic diagram of data update when the number position changes is shown. When the real-time data is associated, if it is detected that the relevant user number has a position change, the signaling sharing platform first searches for the relevant positive key-value pair data with the Key as the user number based on the latest number location information of the user number, and then updates the base station cell location information, registration message time, IP address and domain name information (i.e., Value) of the S-CSCF network element in the positive key-value pair data.

[0083] Then, the signaling sharing platform takes the location information of the base station cell in the Value as the Key to search for the relevant reverse key-value pair data, and updates the user number, registration message time, IP address and domain name information of the S-CSCF network element in the Value of the reverse key-value pair data to ensure that the stored actual number location information is the latest data; wherein, the schematic diagram of the forward key-value pair data update is as follows Fig. 9 As shown, the schematic diagram of the reverse key-value pair data update is as follows Fig.10 shown.

[0084] Step 5: The signaling sharing platform receives a query request carrying the user number or the location information of the base station cell, and returns the query result.
