Abstract

A method, an apparatus and a system for allocating a phone number are disclosed. the method includes: receiving, by an SIP server, an automatic number negotiation request packet sent by an IP phone terminal; allocating, by the SIP server, a corresponding IP phone number to the IP phone terminal according to the received automatic number negotiation request packet; and returning, by the SIP server, the allocated IP phone number to the IP phone terminal, so that the IP phone terminal performs a login by using the IP phone number. The method, apparatus and system can improve efficiency and operability of deploying IP phone numbers for a large quantity of IP phone terminals.

First claim

What is claimed is:

1. A method for allocating a phone number, the method comprising:
receiving, by a Session Initiation Protocol (SIP) server, an automatic number negotiation request packet sent by an Internet Protocol IP phone terminal;
allocating, by the SIP server, a corresponding IP phone number to the IP phone terminal according to the received automatic number negotiation request packet, by:
reading, by the SIP server, the received automatic number negotiation request packet, wherein the automatic number negotiation request packet comprises: the IP phone terminal identifier information and IP phone terminal authentication information;
authenticating, by the SIP server, the IP phone terminal according to the IP phone terminal authentication information read from the automatic number negotiation request packet; and
allocating, by the SIP server according to a preset number allocation algorithm, a corresponding IP phone number to the IP phone terminal corresponding to IP phone terminal identifier information, when the authentication succeeds;

establishing, by the SIP server, a mapping relationship between the allocated IP phone number and the IP phone terminal identifier information of the IP phone terminal;
returning, by the SIP server, the allocated IP phone number to the IP phone terminal;
receiving, by the SIP server, a login request sent by the IP phone terminal, wherein the login request carries the IP phone number; and
returning, to the IP phone terminal, a response indicating a successful login, after the SIP server verifies that the IP phone number corresponds to the IP phone terminal identifier information according to the mapping relationship.

2. The method according to claim 1 , wherein
the IP phone terminal acquires the IP phone terminal identifier information using Dynamic Host Configuration Protocol.

3. The method according to claim 1 , wherein the preset number allocation algorithm comprises one or a combination of the following: allocation according to a number segment specified by a user, or allocation according to a geographic location of a region in which the IP phone terminal is located.

4. The method according to claim 1 , wherein
the IP phone terminal identifier information is one of a device number or an identifier coded according to geographic region.

5. A method for allocating a phone number, wherein the method comprises:
sending, by an IP phone terminal, an automatic number negotiation request packet to an SIP server;
receiving, by the IP phone terminal, an IP phone number that is allocated by the SIP server to the IP phone terminal according to the automatic number negotiation request packet, wherein the IP phone number is allocated by the SIP server by:
reading the received automatic number negotiation request packet, wherein the automatic number negotiation request packet comprises: the IP phone terminal identifier information and IP phone terminal authentication information;
authenticating the IP phone terminal according to the IP phone terminal authentication information read from the automatic number negotiation request packet; and
allocating according to a preset number allocation algorithm, a corresponding IP phone number to the IP phone terminal corresponding to the IP phone terminal identifier information, when the authentication succeeds, wherein the SIP server establishes a mapping relationship between the allocated LP phone number and IP phone terminal identifier information of the IP phone terminal; and

sending, by the IP phone terminal, a login request to the SIP server that includes the received IP phone number, to log in to the SIP server, wherein the SIP server thereafter verifies that the IP phone number corresponds to the IP phone terminal identifier information according to the mapping relationship and receiving a response indicating a successful login, after the SIP server verifies that the IP phone number corresponds to the IP phone terminal identifier information according to the mapping relationship.

6. The method according to claim 5 , wherein after receiving, by the IP phone terminal, an IP phone number that is allocated by the SIP server to the IP phone terminal according to the automatic number negotiation request packet, the method comprises:
saving, by the IP phone terminal, the received IP phone number into a corresponding IP phone configuration file;
reading, by the IP phone terminal, the IP phone number from the IP phone configuration file; and
sending, by the IP phone terminal, a login request to the SIP server by using that includes the IP phone number read from the IP phone configuration file, to log in to the SIP server, when the IP phone terminal restarts.

7. An apparatus for allocating a phone number, the apparatus comprising:
a processor; and
a non-transitory computer readable medium comprising computer-executable instructions for allocating a phone number wherein the processor is configured to execute the computer-executable instructions to perform operations comprising:
receiving an automatic number negotiation request packet sent by an Internet Protocol IP phone terminal;
allocating a corresponding IP phone number to the IP phone terminal according to the received automatic number negotiation request packet by:
reading the received automatic number negotiation request packet, wherein the automatic number negotiation request packet comprises: IP phone terminal identifier information and IP phone terminal authentication information;
authenticating the IP phone terminal according to the IP phone terminal authentication information read from the automatic number negotiation request packet; and
allocating according to a preset number allocation algorithm, a corresponding IP phone number to the IP phone terminal corresponding to the IP phone terminal identifier information, when the authentication succeeds;

establishing a mapping relationship between the allocated IP phone number and the IP phone terminal identifier information; and
returning the allocated IP phone number to the IP phone terminal, so that the IP phone terminal performs a login by using the IP phone number;
receiving a login request sent by the IP phone terminal, wherein the login request carries the IP phone number; and
returning, to the IP phone terminal, a response indicating a successful login, after verifying that the IP phone number corresponds to the IP phone terminal identifier information according to the mapping relationship.

8. The apparatus according to claim 7 , wherein
the IP phone terminal acquires the IP phone terminal identifier information using Dynamic Host Configuration Protocol.

9. The apparatus according to claim 8 , wherein
the IP phone terminal identifier information is one of a device number or an identifier coded according to geographic region.

10. The apparatus according to claim 7 , wherein the preset number allocation algorithm comprises one or a combination of the following: allocation according to a number segment specified by a user, or allocation according to a geographic location of a region in which the IP phone terminal is located.

11. An apparatus for allocating a phone number, the apparatus comprising:
a processor; and
a non-transitory computer readable medium which contains computer-executable instructions for decoding audio data of multiple channels wherein the processor is configured to execute the computer-executable instructions to perform operations comprising:
sending an automatic number negotiation request packet to an SIP server;
receiving an IP phone number that is allocated by the SIP server to the apparatus according to the automatic number negotiation request packet
