Step 15, use the acquired information of the missed call, contact information, SMS and MMS sent by the contact, and email sent by the contact as the contact and the user corresponding to the missed call interaction information between them.

Preferably, in a specific embodiment of the present invention, the user can also use multiple ways to designate corresponding missed calls. For example, when the mobile terminal used by the user has one or more missed calls, the mobile terminal will automatically display the identification of each missed call on its missed call display interface to inform the user that there have been one or more missed calls. Answer the call. Therefore, in a preferred embodiment of the present invention, before step 101, the method may further include: when the user presses and holds one of the missed call identifications on the missed call display interface of the mobile terminal, the missed call Receive calls as user-specified missed calls.

Preferably, in a specific embodiment of the present invention, multiple ways can also be used to display the interaction information to the user.

For example, the acquired interaction information may be directly and sequentially displayed on the display interface of the mobile terminal.

For another example, the identification of various information in the interactive information may also be displayed to the user on the display interface of the mobile terminal in a sub-area; corresponding information.

For example, when the interaction information includes information about missed calls, information about contacts, short messages and multimedia messages sent by contacts, and emails sent by contacts, the user may first share the information with the user on the display interface of the mobile terminal. The region displays information identifiers of missed calls, identifiers of contact information, identifiers of short messages sent by contacts, and identifiers of emails sent by contacts. And when the user clicks the sign of the information of the missed call, then the information of the missed call is displayed to the user; When the logo of the short message is selected, the short message sent by the contact is displayed to the user; when the user clicks the logo of the mail sent by the contact, the mail sent by the contact is displayed to the user.

Through the above method, when the user finds that there is a missed call, he can learn the interaction information between the contact corresponding to the missed call and the user (for example, the information of the missed call, the information of the contact, the information of the contact SMS, MMS and emails sent by contacts), so that the relevant information of the missed call can be preliminarily obtained according to the above interaction information. Therefore, even when the user is relatively busy, it is possible to help the user recall things that may be related to the missed call when seeing a missed call.

The contacts whose activity F is greater than the preset second threshold are formed into an active contact set.

Preferably, in a specific embodiment of the present invention, the above activity F can be calculated according to the following formula:

F=α·f ₁ +β·f ₂ +γ·f ₃ (1)

Wherein, α, β and γ are weighting factors, and α+β+γ=1; specific values of α, β and γ can be preset according to actual application conditions. Said f1 is the frequency _of calls between the user and the contact within the predetermined _second time period, f2 is the frequency of sending and receiving short messages between the user and the contact within the predetermined second time period, and _f3 is the frequency of the user's calls within the predetermined second time period. The frequency of sending and receiving emails with the contact in the second time period. The larger the F value, the greater the activity of the contact.

Preferably, in a specific embodiment of the present invention, the relationship value P between the two contacts in step 03 can be calculated according to the following formula:

P=a ₁ ·k ₁ +a ₂ ·k ₂ (2)

Wherein, a ₁ and a ₂ are the weighting coefficient of the contact P ₁ and the weighting coefficient of the contact P ₂ respectively, and a ₁ +a ₂ =1; the specific values of a ₁ and a ₂ can be preset according to the actual application situation. The k ₁ is the frequency at which the contacts P ₁ and P ₂ appear in the same group text message within the predetermined second time period, and the k ₂ is the frequency of the contacts P ₁ and P ₂ in the predetermined second time period How often the segment co-occurs in the same group message. A larger P value indicates a stronger connection between two contacts.
