Saved in the module, as shown in Figure 3, includes the following steps:

 Step 301: The user registers by editing the username and password.

 Step 302: After the registration is successful, go to step 303;

 Step 303: Send the user name, password, and mobile phone number to the network storage module for saving. FIG. 4 is a flowchart of adding a friend function according to an embodiment of the present invention. The process of adding a friend is similar to the process of adding a friend by a conventional IM software. As shown in FIG. 4, the following steps are included:

 Step 401: First, the user sends a request to add a friend;

 Step 402: Whether the other party agrees, after the other party agrees, step 403 is performed, and the other party does not agree, step 407 is performed;

 Step 403: Adding a friend action is completed, but the special feature of the software client is that in order to verify the identity of the operator in the process of updating the contact, a key between the generating parties is needed; Step 404: Obtaining the usernames of both parties ;

 Step 405: Obtain the current mobile phone number of the user;

 Step 406: Send the key, the two user names, and the current mobile phone number to the network storage module for storage;

 For example, the user named userA, the mobile phone number is 1234567890, sends a friend request to the user named userB. After userB agrees, the software client generates the key ABCDEFG2 between the two, and generates the generated key ABCDEFG2. The user name user A, the user name userB, and the mobile phone number 1234567890 of the operation initiator are sent to the network storage module, and are saved by the network storage module.

 Step 407: The process terminates.

FIG. 5 is a function diagram of an initiation number change notification provided by an embodiment of the present invention, as shown in FIG. 5, Includes the following steps:

 Step 501: After the mobile phone number of the user is changed, select a friend who needs to be notified in the friend list of the friend selection interface;

 Step 502: After selecting a friend who needs to be notified, enter the number editing interface;

 Step 503: Determine whether the software can directly obtain the current user's mobile phone number, if not, go to step 504, otherwise, go to step 505;

 Step 504: The number editing interface new number edit box is unavailable, directly displays the current number read, without user input, and then proceeds to step 506;

 Step 505: The number editing interface new number edit box is available, the user is required to input the current mobile phone number, and then step 506 is performed;

 Step 506: After obtaining the new mobile phone number, encrypting the recipient user name and the sender's new mobile phone number, and generating a number change message to be sent to the network server, where the sender's new mobile phone number is saved to the network server network. Storage module.
