The multi-card terminal is a terminal capable of installing at least two Subscriber Identity Module (SIM) cards, and the existing terminal is generally a dual-card terminal, that is, a terminal capable of installing two SIM cards. The demand of the dual card terminal is great, and more than 90% of the terminals sold in the market at present are dual card terminals. When a user uses the dual-card terminal, one SIM card can be used as a private SIM card to communicate with acquaintances, such as relatives, friends and the like, and the other SIM card can be used as a public SIM card to communicate with public groups, such as working, express delivery, intermediaries and the like, through the public SIM card.

In the prior art, when a user uses a multi-card terminal to communicate with other terminals, the user does not know which of the SIM cards installed on the currently used multi-card terminal is a public SIM card and which of the SIM cards is a private SIM card, or the user can easily mix the SIM cards with each other. And it is highly likely that the number (called number) corresponding to the other terminal is an unknown number, and the user cannot distinguish whether the unknown number is an acquaintance number or a public number, such as a number of a harassing call, an advertising promotion, a training agency, or the like.

Based on the above situation, the user may use the SIM card contrary to his own will to communicate with the unknown number, such as using a private SIM card to dial a public number, or using a public SIM card to dial a number of an acquaintance, which may cause the problems of disclosure of his own privacy, refusal of the acquaintance, etc., and thus inconvenience is brought to the life of the user, and the user experience is poor.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

fig. 1 is a schematic diagram of a selection process of an SIM card according to embodiment 1 of the present invention, where the process includes the following steps:

s101: receiving an inquiry request sent by a terminal, wherein the inquiry request carries a first number to be communicated with the terminal.

The method for selecting the SIM card provided by the embodiment of the invention is applied to a server.

When the multi-card terminal communicates with a certain number, the number corresponding to which SIM card installed by the user is used can be displayed for the user to communicate with the number. The terminals in the present invention all refer to multi-card terminals, and are hereinafter referred to as terminals for short.

The terminal sends a query request to the server, wherein the query request carries a first number to be communicated with the terminal, and the terminal requests the server to push which SIM card is preferentially used by the terminal to communicate with the first number when the terminal communicates with the first number. The communication can be a call, and can also be a message such as a short message, a multimedia message and the like.

Wherein, the query request may be sent when the terminal recognizes that the user has input the complete first number.

Preferably, the query request is sent when the terminal identifies that the user has input a complete first number and determines that the second storage space preset by the terminal does not store the corresponding relationship between the first number and the identification information of the SIM card.

S102: according to each feature saved in advance, determining a first parameter of the first number for each feature, and according to a weight value corresponding to each parameter range of each feature saved in advance and the first parameter of each feature, determining each first weight value of the first number.

The server stores each feature and a weight value corresponding to each parameter range of each feature in advance.

After receiving a query request carrying a first number, a server determines, for each feature stored in advance, a first parameter of the first number for the feature. The characteristics may be, for example, a number attribution, a number owner, a number real name system, and the like. The first parameter of the first number for the feature of the number attribution can be Shanghai, Beijing, etc.; the parameter of the first number aiming at the characteristic of the person to which the number belongs can be an enterprise or an individual; the parameter of the first number for the real-name system feature of the number can be a real-name system or a non-real-name system.

Then, the server determines each first weight value of the first number according to a weight value corresponding to each parameter range of each feature stored in advance, specifically, for each first parameter of each feature, matching the first parameter of the feature with each parameter range of the feature stored in advance, taking the parameter range in which the first parameter of the feature is located as a target parameter range, and taking the weight value corresponding to the target parameter range as the first weight value of the first number for the feature.

The process of determining the number attribution belongs to the prior art, and is not described in detail in the embodiment of the invention. The process of determining the person to which the number belongs to the prior art, and details are not described in the embodiment of the invention. The process of determining whether a number is a real name belongs to the prior art, and is not described in detail in the embodiment of the present invention.

S103: and determining a correlation value of the public number and the first number according to each first weight value and each second weight value corresponding to the prestored public number.

And after each first weight value corresponding to the first number is determined, a correlation value between the public number and the first number can be determined according to each first weight value and each second weight value.

Specifically, the correlation value between the common number and the first number may be determined according to each first weight value and each second weight value, and a euclidean distance algorithm.

S104: and judging whether the correlation value is larger than a preset threshold value, if so, determining that the type of the first number is a public number, and otherwise, determining that the type of the first number is a private number.

The server pre-stores a threshold value, namely a correlation threshold value, and after the correlation value between the public number and the first number is determined, the correlation value can be compared with the preset threshold value to judge whether the type of the first number is the public number or the private number. Specifically, if the correlation value is greater than the threshold, the type of the first number is determined to be a public number, and if the correlation value is not greater than the threshold, the type of the first number is determined to be a private number.

S105: and according to the type of each second number which is predetermined and stored aiming at the terminal, taking the second number which is matched with the type of the first number as a target number, and sending the target number to the terminal to enable the terminal to display the identification information of the SIM card corresponding to the target number, wherein the second number is the number which is respectively corresponding to at least two SIM cards installed on the terminal.

The server may store in advance a number corresponding to each SIM card installed in each terminal, and a type of each number determined in advance. After receiving a query request sent by a terminal, a server may determine, according to each number corresponding to each terminal stored by the server, each second number corresponding to the terminal, and determine the type of each second number, where the second number is a number corresponding to an SIM card installed on the terminal. The types of numbers include public numbers and private numbers.

After determining the type of the first number and the type of each second number, the server matches the type of each second number with the type of the first number, takes the second number matched with the type of the first number as a target number, and sends the target number to the terminal, so that the terminal displays the identification information of the SIM card corresponding to the target number.

A second number that matches the type of the first number, specifically, if the type of the first number is a private number, the type of the second number that matches the type of the first number is a private number; if the type of the first number is a public number, the type of the second number matching the type of the first number is a public number.

The terminal stores the corresponding relation between the identification information of each SIM card and each number, and after receiving the target number sent by the server, the terminal determines the identification information of the SIM card corresponding to the target number according to the target number and the stored corresponding relation between the identification information of each SIM card and each number, and displays the identification information of the SIM card corresponding to the target number. The identification information of the SIM card may be the SIM card 1 or the SIM card 2.

The correspondence between the terminal and the second number stored in the server may be that the terminal sends the second number corresponding to each SIM card installed in the terminal to the server, and the server receives and stores the second number.

The process of the server determining the type of each second number may specifically be: and the terminal sends each second number and the type of each second number set by the user to the server, and the server receives and stores the second numbers and the types of the second numbers set by the user.

In the embodiment of the invention, the server determines each first weight value of the first number according to each characteristic so as to determine the type of the first number, determines the target number matched with the type of the first number according to the type of each second number, and sends the target number to the terminal, so that the terminal displays the identification information of the SIM card corresponding to the target number, and a user can select a more suitable SIM card to communicate with the first number according to the identification information of the SIM card displayed by the terminal, thereby avoiding privacy disclosure, bringing convenience to life and improving user experience.

Example 2:

in order to determine the type of the number more intelligently and improve the user experience, on the basis of the above embodiment, in the embodiment of the present invention, the process of determining the type of each second number in advance includes:

for each second number, identifying a first number of first communication records and a second number of second communication records according to each communication record saved for the second number, wherein the first communication records record communication information of the second number and a private number, and the second communication records record communication information of the second number and a public number; and if the first number is larger than the second number, determining the type of the second number as a private number, and otherwise, determining the type of the second number as a public number.

In order to more accurately determine the type of the second number, in an embodiment of the present invention, the server stores each communication record of each number, and stores whether the type of the communication number recorded in each communication record is a public number or a private number, and when determining the type of each second number, the type of the second number may be determined according to the type of a number in each communication record stored for the second number, the number communicating with the second number.

Specifically, for each second number, the server identifies a first number of first communication records of the second number, which are communicated with private numbers, and a second number of second communication records of the second number, which are communicated with public numbers, according to each communication record saved for the second number, and determines the type of the second number according to the first number and the second number.
