Referring to fig. 2, an embodiment of the present invention provides a method for acquiring a contact number based on a block chain, where an execution subject of the method is a network device, and the method includes the following specific steps:
step 201: receiving a call request sent by a calling terminal;
in the embodiment of the invention, the calling request carries a first contact number called by the calling terminal, and the first contact number is a contact number stored in the calling terminal by the first user. And in the calling terminal, the contact corresponding to the first contact number is the second user.
Step 202: acquiring user information bound with the first contact number from the block chain according to the first contact number;
in the embodiment of the present invention, the block chain stores the user information bound with the first contact number, where the user information may be uploaded to the block chain by a second user corresponding to the first contact number, and the user information may also be uploaded to the block chain by an operator corresponding to the first contact number. By utilizing the characteristics of decentralized block chain, irreversible chain, non-falsification and the like, the user information is ensured to be real and reliable, and meanwhile, the query is convenient.
The user information may include: network access unique identification, such as: international Mobile Subscriber Identity (IMSI), Globally Unique Temporary UE Identity (GUTI), and the like; and/or user identity information of the terminal for identifying the true identity of the user, such as: user name, identification card ID, etc.
Optionally, before performing step 202, the network device calls a terminal corresponding to the first contact number;

Further, when the call fails, step 202 is performed.
In an embodiment of the invention, a call failure indicates that the second user has changed the contact number, and that the first contact number has not been available for use.
Further, the network device queries the user information bound with the first contact number in the block chain according to a preset search time range, and acquires the user information in the preset search time range;
in the embodiment of the invention, after the first contact number is deactivated and a certain time elapses, the first contact number may be reactivated and assigned to a new user, thereby binding new user information. In order to avoid the error of user information query, the network device sets a search time range in advance, only queries the user information within the search time range, and ensures that the acquired user information corresponds to the second user.

in the embodiment of the present invention, a special case is considered, in which the initial user of the first contact number is user a, after user a changes the contact number, the first contact number is reassigned to user B, and then user B also changes the contact number. At this time, on the blockchain, the user information of the user a and the user B can be searched through the first contact number, so that it is more appropriate to select the user information newly added to the blockchain, that is, the user information of the user B.
Step 203: acquiring a second contact number bound with the user information from the block chain according to the user information;
in the embodiment of the invention, according to the user information, a second contact number bound with the user information is inquired on the block chain, and the second contact number is a new contact number of a second user.
Further, when the number of the second contact numbers is greater than 1, the second contact number newly added to the block chain is acquired.
In the embodiment of the present invention, the second user may replace the first contact number several times, so that several second contact numbers bound to the user information of the second user are queried in the blockchain. Therefore, the network device needs to acquire the second contact number newly added to the blockchain, which is the contact number being used by the second user.
Step 204: sending the second contact number to the calling terminal;
in the embodiment of the invention, the network equipment sends the acquired second contact number to the calling terminal, so that the first user of the calling terminal obtains the second contact number currently used by the second user.
Optionally, after step 204, the network device determines, according to the second contact number, a called terminal corresponding to the second contact number; establishing a call between a calling terminal and a called terminal;
in the embodiment of the invention, the network equipment establishes the conversation between the calling terminal and the called terminal according to the second contact number, so that the step that the calling terminal uses the second contact number to initiate the call again is omitted, and the communication efficiency is improved.
In the embodiment of the invention, the network equipment acquires the user information bound with the first contact number in the blockchain through the first contact number called by the calling terminal, then acquires the second contact number bound with the user information in the blockchain according to the user information, and sends the second contact number to the calling terminal. And the block chain is utilized to quickly acquire the contact number of the calling object of the calling terminal, so that the communication efficiency is improved.

Step 302: receiving a second contact number sent by the network equipment;
in this embodiment of the present invention, the second contact number is obtained by the network device by querying in the blockchain according to the first contact number, and the specific process may refer to the description of step 202 and step 203 in fig. 2, which is not described herein again.
Further, after step 302, the calling terminal replaces the first contact number with the second contact number, and the step of manually changing the address book by the user is omitted.
In the embodiment of the invention, the calling terminal calls through the first contact number, the network equipment acquires the user information bound with the first contact number from the block chain according to the first contact number, and acquires the second contact number bound with the user information from the block chain according to the user information. And the block chain is utilized to quickly acquire the contact number of the calling object of the calling terminal, so that the communication efficiency is improved.
Referring to fig. 4, an embodiment of the present invention provides a method for acquiring a contact number based on a block chain, which includes the following specific steps:
step 401: a calling terminal sends a calling request to network equipment;
in the embodiment of the invention, the calling request carries a first contact number called by the calling terminal, and the first contact number is a contact number stored in the calling terminal by the first user.
