Description

Method for storing and querying number information in calling name display service

technical field

The invention relates to a method for storing and inquiring telephone numbers and their corresponding information in a communication system.

Background technique

At present, among the many new services launched by various operators, the calling name display service CNAP (Calling Name Presentation) is somewhat similar to the caller display service used in the current GSM network, but it is also different. The calling name display service means that after the user applies for this service from the business hall of the operator, he can submit a mapping table about the mapping relationship between the contact number and the name, unit and address corresponding to the number to the communication system. Store this mapping table in the switching office of the communication system, so that when some other user calls this user, if the name and number information of the calling user has been input into the communication system by the called user, then when the call is connected When ringing with the called communication terminal, information such as the name, unit and address of the calling user will be displayed on the communication terminal of the called user.

In the process of implementing the calling name display service, the corresponding switching equipment of the switching office of the communication system needs to store a large number of user phone numbers and their corresponding user detailed information. In the current communication system, the number of users is increasing rapidly over time. In this way, if the phone numbers of these users and their corresponding user details are not effectively stored and managed, when querying the calling party’s phone number and corresponding user details, the phone number Improper storage and management of the corresponding user detailed information brings great inconvenience to the query. On the user side, it will cause a large delay in call connection and display of number information on the called party, thereby reducing The throughput rate of the corresponding switching equipment in the switching office.

Contents of the invention

The purpose of the present invention is to propose a method for storing and inquiring number information in the calling name display service, using the method for storing and inquiring number information can be effectively stored and managed, and the desired number information can be inquired more quickly.

In order to achieve the above-mentioned purpose, the solution of the present invention is as follows: the storage steps of the number information are as follows:

Divide the number information into different number analysis sets;

According to the range determined by each number analysis set, the number information within the scope of each number analysis set is stored in different directory data nodes.

The query steps for the number information are as follows:

Store the pre-divided different number analysis sets in different directory data nodes, so that each number analysis set has a corresponding relationship with each directory data node;

Store the corresponding relationship between the number analysis set and the directory data node in the request node;

The requesting node determines the corresponding number analysis set according to the received number and sends the request information of the requesting node to the corresponding directory data node according to the corresponding relationship between the number analysis set and the directory data node, and receives the directory data node The corresponding number information replied by the data node.

The query of number information can also be realized by the following schemes:

Store the pre-divided different number analysis sets in different directory data nodes, so that each number analysis set has a corresponding relationship with each directory data node;

Set up a proxy directory data node;

Store the corresponding relationship between the number analysis set and the directory data node in the proxy directory data node;

The agent directory data node determines the corresponding number analysis set according to the received number and replies the number information correspondingly stored in the directory data node to the requesting node according to the corresponding relationship between the number analysis set and the directory data node.

By adopting the storage and query method of number information in the calling name display service of the present invention, a large number of user number information in the calling name display service can be effectively stored and managed, and the query of the calling number can be improved. The speed is improved, and the delay in displaying the calling number information at the called end is reduced.

Detailed ways

The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Refer to Figure 1 for the scheme of distributed storage of user number information in the calling name display service, and take the distributed storage of fixed phone numbers and mobile phone numbers in my country as an example.

Step 10: In the relevant equipment of the exchange, define a number analysis set for each directory data node of the directory used to store all number information in the country, and different directory data nodes can be defined to represent different administrative regions of my country;

Step 11: Divide all the numbers into different number analysis sets according to the rules. For example, telephone numbers across the country can be divided into different number analysis sets. For example, the number analysis set in Beijing is defined as "8610", while the number analysis set in Shenzhen is defined as "86755". The number analysis collections to which the phone number belongs are all located in the Beijing area;

Step 12: According to the range determined by each number analysis set obtained, store the number information within the scope of the number analysis set into different directory data nodes, such as the above example, store the number information within the range of the number analysis set representing the scope of the Beijing area in step 11 above Store the phone numbers in the directory data node representing Beijing, and store the phone numbers within the scope of the number analysis set representing Shenzhen in the directory data node representing Shenzhen;

Through the above-mentioned storage process of number information, the corresponding relationship between the number analysis set and the directory data node can be realized, so that any telephone number in the country belongs to a certain number analysis set. According to the corresponding relationship, it further belongs to A directory data node, which lays the foundation for the subsequent rapid query of corresponding number information.

Utilize the above-mentioned number information storage method equally, also can carry out the same operation to the mobile phone number of the whole country, for example can divide all mobile phone numbers with "86139, 86138, 86137, 86136, 86135" as a prefix into a number The analysis set divides all mobile phone numbers with "86130, 86131" as prefixes into another number analysis set, and stores the mobile phone numbers within the scope of these two number analysis sets into two different directory data nodes Among them, one of the directory data nodes is used to represent all mobile phone numbers of "China Mobile", and the other directory data node is used to represent all mobile phone numbers of "China Unicom", so as to realize all mobile phone numbers in the country Effective storage and management provide a fast way to search for the calling number of mobile calls.

In the communication system, after the user applies for the calling name display service, when other users call this user, the corresponding switching equipment of the exchange will query the detailed information corresponding to the number such as name, address, Units, etc., send the inquired detailed information to the communication terminal of the called user for display, so that the called user can know the detailed information of the calling party and can selectively answer the call.

When the exchange-related equipment receives a certain telephone number, how to query the detailed information corresponding to the number according to the received number refers to Figure 2. The scheme described in Figure 2 uses the requesting node to locate the directory data node to query the detailed number of the number information. The requesting node refers to an entity in the switching device that receives calling information and makes a request to query detailed number information corresponding to the calling number. In this solution, a directory data node positioning module is set in the request node, and its function is to locate the corresponding number analysis set according to the calling number, thereby addressing the corresponding directory data node; The relationship is also stored in the request node. When the request node receives a calling phone number and wants to know more detailed number information corresponding to the number, it first determines the number analysis set it belongs to according to the received number, and then requests The directory data node positioning module in the node queries the directory data node that stores the number information corresponding to the number according to the determined number analysis set and the corresponding relationship between the number analysis set and the number data node, and then locates the directory data node The module sends the received request information to the inquired corresponding directory data node, and then the directory data node replies the stored corresponding number information to the requesting node through the directory data node location module.

The query process of number information can also be completed by the agent of the directory data node. Refer to Figure 3 for the realization process. It is necessary to select a directory data node and set it to have the function of proxy. We define this directory data node For the proxy directory data node, set the directory data node positioning module at the proxy directory data node, and store the corresponding relationship between the number analysis set and the directory data node in the proxy directory data node, when the requesting node receives the caller If you want to further query the number information of the number, the requesting node sends the request information to the directory data node positioning module of the agent directory data node, and the directory data node positioning module determines the corresponding number according to the number The analysis set, the directory data node positioning module determines whether the number belongs to the agent directory data node according to the number analysis set, and if so, the directory data node positioning module locates the corresponding The directory data node inquires out the corresponding number information and replies to the requesting node; if it does not belong, the agent directory data node starts the proxy function, and the directory data node positioning module sends the request information to the corresponding other according to the number analysis set In the directory data node, the corresponding directory data node is located to the corresponding directory data node according to the corresponding relationship between the number analysis set and the directory data node, and the corresponding number information is queried by proxying the directory data in the directory data node The node location module replies to the requesting node.

The number analysis set is composed of some numbers with variable lengths, so the directory data node also stores the corresponding relationship between region information and these numbers with variable lengths, such as the directory data storing telephone numbers in the "Shenzhen" area The corresponding relationship between "86755" and "Shenzhen" should also be stored in the node, which is ready when the directory data node fails to query the number information (possible reasons include that the corresponding number information does not exist, the number information data itself has been damaged, etc.) or When accessing other directory data nodes as an agent, the return information is not obtained within the predetermined time. In order to provide the calling name display service within the delay time that the user can tolerate, exception handling can be performed: according to the above-mentioned storage in the directory data node The corresponding relationship between the number with a variable length and the area information is queried for the area information corresponding to the calling number, and the queried area information is sent to the called communication terminal for display. As in the above example, when the number information of the calling number 86755168 does not exist in the corresponding directory data node or the stored data has been damaged, according to the corresponding relationship between "86755" and "Shenzhen" in the directory data node, the " "Shenzhen" is sent to the communication terminal of the called user as the detailed number information to be queried for display, so that the called user knows that the incoming call is made by a person in Shenzhen.

The above disclosure is the best implementation, but the present invention is not limited to the content disclosed in this implementation, because the protection scope of the present invention is determined by the claims.
