Abstract
The invention further relates to a kind of methods for realizing non-proxy IP refusal incoming call function based on Session Initiation Protocol, specifically includes the following steps: (1) home gateway receives INVITE call request, judge whether the server being currently configured is domain name, if it is, continuing step (2)；Otherwise, continue step (3)；(2) dns resolution is carried out to the server domain name, saves all IP address parsed；(3) whether the IP address for judging that dns resolution obtains is consistent with the source IP address of INVITE call request, if it is, the call request that normal access is described；Otherwise, refuse the call request.Using the method for the invention for realizing non-proxy IP refusal incoming call function based on Session Initiation Protocol, judge whether source IP is consistent with the server of current-configuration from source, guarantee that the INVITE call request of the server only from oneself registration could be accessed, so that it is inconvenient to client's bring to efficiently avoid harassing call.
Description
Technical field
The present invention relates to technical field of electronic equipment, more particularly to the Home Gateway Technology field with VOIP function, tool
Body refers to a kind of method for realizing non-proxy IP refusal incoming call function based on Session Initiation Protocol.
Background technique
Currently, with EPON (Ethernet Passive Optical Network, Ethernet passive optical network) and
Universal, the Yi Jiguo of GPON (Gigabit Passive Optical Network, gigabit passive optical network) technology at home
The technology development strategy of family's light entering and copper back, relevant home gateway product, such as various EPON HGU (Home Gateway
Unit, home gateway unit), GPON HGU etc. each big city is moved into swift and violent state, come into every household.
Due to these carry VoIP (Voice over Internet Protocol) functions home gateway products it is general
And use, voip technology is widely applied in daily life, and VoIP is exactly by analog signal (Voice) number in brief
Word does real-time delivery on IP network (IP Network) in the form of data packet (Data Packet).
Family gateway equipment with voice over ip feature, telephony feature can bring many conveniences to client, but following
, various harassing calls emerge one after another.At present in existing network environment, harassing call emerges one after another, and is because of VOIP in many degree
Phone is based on internet, and is point-to-point calling, as long as learning IP, so that it may and a large amount of INVITE that sends is called,
To cause to harass.
Summary of the invention
The purpose of the present invention is overcoming the above-mentioned prior art, provides and a kind of meet that process is simple, user
Just, the method applied widely that non-proxy IP refusal incoming call function is realized based on Session Initiation Protocol.
To achieve the goals above, of the invention that the method for non-proxy IP refusal incoming call function is realized such as based on Session Initiation Protocol
Under:
The method for realizing non-proxy IP refusal incoming call function based on Session Initiation Protocol, is mainly characterized by, the method packet
Include following steps:
(1) home gateway receives INVITE call request, judges whether the server being currently configured is domain name, if so,
Then continue step (2)；Otherwise, continue step (3)；
(2) dns resolution is carried out to the server domain name, saves all IP address parsed；
(3) whether the IP address for judging that dns resolution obtains is consistent with the source IP address of INVITE call request, if so,
The then normal access call request；Otherwise, refuse the call request.
Preferably, the step (1) specifically includes the following steps:
(1.1) home gateway receives INVITE call request；
(1.2) judge whether the server being currently configured is domain name, if it is, continuing step (2)；Otherwise, continue to walk
Suddenly (3).
Preferably, the home gateway of the step (1) is the home gateway with IP-based voice transmission capabilities.
Using the method for the invention for realizing non-proxy IP refusal incoming call function based on Session Initiation Protocol, source is judged from source
Whether IP is consistent with the server of current-configuration, guarantees the INVITE call request ability of the server only from oneself registration
It is accessed, so that it is inconvenient to client's bring to efficiently avoid harassing call.
Detailed description of the invention
Fig. 1 is the method for the invention for realizing non-proxy IP refusal incoming call function based on Session Initiation Protocol.
Specific embodiment
It is further to carry out combined with specific embodiments below in order to more clearly describe technology contents of the invention
Description.
The method that non-proxy IP refusal incoming call function should be realized based on Session Initiation Protocol of the invention, including following steps:
(1) home gateway receives INVITE call request, judges whether the server being currently configured is domain name, if so,
Then continue step (2)；Otherwise, continue step (3)；
(1.1) home gateway receives INVITE call request；
(1.2) judge whether the server being currently configured is domain name, if it is, continuing step (2)；Otherwise, continue to walk
Suddenly (3)；
(2) dns resolution is carried out to the server domain name, saves all IP address parsed；
(3) whether the IP address for judging that dns resolution obtains is consistent with the source IP address of INVITE call request, if so,
The then normal access call request；Otherwise, refuse the call request.
As the preferred embodiment of the present invention, the home gateway of the step (1) is to pass with IP-based voice
The home gateway of transmission function
In a specific embodiment of the invention, the present invention relates to one kind to realize that non-proxy IP refuses incoming call based on Session Initiation Protocol
Method.When including establishing calling based on Session Initiation Protocol, judge whether IP is consistent with the server of current-configuration, if not
Harassing call is truncated to be effectively prevented the incoming call of illegal IP in consistent refusal incoming call.
The method of the technical program is specifically included when receiving INVITE call request, judge source IP whether with currently match
The server set is consistent, if inconsistent, refuses incoming call.When the server of configuration is domain name, need first to carry out dns resolution.
Multiple IP may be parsed by carrying out dns resolution, be required to be compared.
In order to effectively refuse the harassing call in VOIP phone, it is non-based on Session Initiation Protocol realization that the invention proposes one kind
The method of Agent IP refusal incoming call.
The method that this kind realizes non-proxy IP refusal incoming call based on Session Initiation Protocol, is mainly characterized by, the control method
The following steps are included:
1, based on Session Initiation Protocol there is the home gateway of VOIP function to receive INVITE call request
2, judge be currently configured server whether domain name, if it is carry out step 3, if it is not, entering step 4
3, dns resolution is carried out to server domain name, saves all IP parsed
4, server ip and the INVITE source IP requested are compared, if unanimously, receiving the INVITE, normally entering
Call flow；If it is inconsistent, refusing the calling.
Using the method for the invention for realizing non-proxy IP refusal incoming call function based on Session Initiation Protocol, source is judged from source
Whether IP is consistent with the server of current-configuration, guarantees the INVITE call request ability of the server only from oneself registration
It is accessed, so that it is inconvenient to client's bring to efficiently avoid harassing call.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that can still make
Various modifications and alterations are without departing from the spirit and scope of the invention.Therefore, the description and the appended drawings should be considered as illustrative
And not restrictive.
