Description

Method and system for realizing calling user name display

technical field

The invention relates to call processing technology, in particular to a method and system for displaying calling user names.

Background technique

In call processing technology, the calling name presentation (Calling Name Presentation, CNAP) service is used as a calling supplementary service. The calling user name information corresponding to the phone number, and then display the calling user name information on the called user terminal.

Two implementations of CNAP are defined in the 3GPP protocol, namely based on the implementation of Home Location Register (Home Location Register, HLR) and the implementation based on name database (Namedatabase). The user name information is stored in the HLR, and when the call is initiated, the calling name information in the HLR is inserted into the visitor location register (Vacation Location Register, VLR) through location update; The user name information is stored in the name database. When a call is initiated, the calling user name information is obtained by querying the name database, and then the calling user name information is transmitted to the called user terminal.

Above scheme has following shortcoming:

In the implementation scheme based on HLR, at first, the calling user name information is stored in the HLR, which wastes the database space of the HLR/VLR, and the calling user name information is transmitted through the insert operation, which also increases the link load;

Secondly, the calling user cannot customize the display of the calling user name according to the called user number, and the called user cannot customize the display of the calling user name according to the calling user number;

Thirdly, only monthly rent and billing for each modification can be realized, and pay-per-use billing cannot be realized;

In the implementation scheme based on the name database, querying the user name information of the calling party in the name database requires more modifications to the Mobile Switch Center (MSC), and the addition of the query process leads to an increase in the connection time.

Due to equipment limitations, the above solutions have not yet been applied in existing communication networks.

In addition, in practical applications, there are also the following terminal-based solutions for displaying the calling user name:

Store the user name information of the calling user in the called user terminal or the Subscriber Identity Module (SIM). Query the database of the called user terminal or SIM, obtain the calling user name information corresponding to the calling number, and then display the calling user name information on the display screen.

The terminal-based solution for displaying the calling user name has the following disadvantages:

First, only the called user can customize the calling user name display service, and the calling user cannot customize the calling user name display service;

Secondly, when the called user terminal is lost, the SIM is replaced, and the caller's name information cannot be displayed on the called user terminal in the case of a user terminal that does not store the user name information of the calling user;

Thirdly, since the calling user name information is stored on the called user terminal and SIM, if the terminal and SIM are lost, private information will be leaked.

Contents of the invention

The technical problem solved by the present invention is to propose a method and system for displaying the calling user name, so as to realize that the calling user can still be displayed on the called user terminal when the terminal or SIM is replaced without wasting HLR/VLR space. name, and the calling user name display can be customized by both the calling user and the called user.

In order to solve the above problems, the method for realizing the display of the calling user name proposed by the present invention comprises the following steps:

a. After receiving the call request sent by the calling user terminal, the calling service switching entity sends a monitoring data packet to the calling service control entity;

b. After the calling service control entity receives the monitoring data packet, it inquires whether there is the preset calling user name information of the calling user in the database, and if the query result is yes, it sends the information to the calling service switching entity Carry the monitoring data packet of the calling user name information; if the query result is no, then send the monitoring data packet not carrying the calling user name information to the calling service switching entity;

After receiving the monitoring data packet sent by the calling service control entity, the calling service switching entity judges whether the calling user name information is received, and if received, when sending the connection establishment primitive message to the called service switching entity, Carry the calling user name information; if not received, when sending the connection establishment primitive message to the called service switching entity, do not carry the calling user name information;

If the called service switching entity receives the connection operation that carries the information of the protagonist user name, it will carry the calling user name information when sending the monitoring data packet to the called service control entity; if not, it will not report the monitoring data packet to the called service control entity carrying the calling user name information set by the calling user;

The called service control entity judges whether the monitoring data packet sent by the called service switching entity carries the calling user name information; if it is judged to be yes, inquires whether there is a calling user preset by the called user in the called service control entity name information, if so, query whether the called user is allowed to display the calling user name information preset by the calling user, if allowed, then carry the calling user setting when sending the connection operation to the gateway mobile switching center the calling user name information; if the called user is not allowed to display the calling user name information preset by the calling user and there is a calling user name information preset by the called user, it will be issued to the gateway mobile switching center During the connection operation, carry the calling user name information set by the called user; when the called service control entity judges that the monitoring data packet sent by the called service switching entity does not carry the calling user name information, query the called service Whether there is the calling user name information preset by the called user in the control entity, if so, when the connection operation is issued to the gateway mobile switching center, the calling user name information set by the called user is carried;

c. The gateway mobile switching center sends the calling user name information preset by the calling user or the calling user name preset by the called user to the called user terminal when establishing the call connection.

Correspondingly, the present invention also proposes a system for displaying a calling user name, including a calling user terminal, a service control entity, a service switching entity, and a called user terminal. The service switching entity includes a calling service switching entity, The called service switching entity and the gateway mobile switching center, the key is that the service control entity includes:

The calling service control entity is used to store the calling user name information set by the calling user; and search for the stored calling user name information set by the calling user, and when the query result is yes, firstly send the calling user name information to the calling user The calling service switching entity carries the calling user name information when issuing a connection operation, and the calling service switching entity sends a monitoring data packet carrying the calling user name information when sending a connection establishment primitive message to the called service switching entity; If the query result is no, the calling user name information is not carried when the connection operation is sent to the calling service switching entity, and the connection establishment primitive message is not carried when the calling service switching entity sends the connection establishment primitive message to the called service switching entity The monitoring data packet of the calling user name information;

After the called service switching entity receives the monitoring data packet sent by the calling service switching entity, it judges whether the calling user name information is carried, and if the calling user name information is carried, it will carry the calling user name information. The monitoring data packet of the information is sent to the called service control entity; otherwise, it is not carried;

The called service control entity is used to judge whether the monitoring data packet sent by the called service switching entity carries the calling user name information; Calling user name information, if so, query whether the called user is allowed to display the calling user name information preset by the calling user, if allowed, then carry the calling user name information when sending the connection operation to the gateway mobile switching center The calling user name information set by the user; if the called user is not allowed to display the calling user name information preset by the calling user and there is the calling user name information preset by the called user, the mobile exchange at the gateway When the center issues a connection operation, it carries the calling user name information set by the called user; when the called service control entity judges that the monitoring data packet sent by the called service switching entity does not carry the calling user name information, query Whether there is the calling user name information preset by the called user in the called service control entity, if so, when sending the connection operation to the gateway mobile switching center, carry the calling user name information set by the called user;
