Abstract
The present invention provides a method and system of internet phone callback. The general process provided by the invention comprises the following steps: a client downloads and installs a mobile phone app, and registers and logs in an account; the client sends ajax signals to a dispatch server, the server receives the signals and then determines whether the signals are a request initiated by a normal client, and the server screens a sip floor server arranged in advance; after an upper device receives sip signals, the upper device is linked to a gateway device, the gateway device calls the user who firstly initiates the call, and the user who firstly initiates the call gets through the call; the gateway device is configured to call a called user to allow both sides to perform normal communication by telephone. According to the invention, the problem of usage demands of an internet phone callback service is solved; and moreover, the problem is solved that too high concurrence environment leads to an unstable internet phone callback system through erecting a server cluster configuration with balanced load, therefore the communication quality is improved, so that the standard of the high quality service of a internet phone callback service is achieved.
Description
Technical field
The invention belongs to network communication field, particularly relate to a kind of method and its system applied of networking telephone clawback.
Background technology
Community network technical development is now more and more faster, the networking telephone also accept by more people and use, user can be set up with phone by PC computer, cell phone network etc. and converse.Current telephone redialing technology is also applied in network phone system, and application is more and more, the networking telephone redialing method therefore needing a kind of public of being suitable for use and its system applied.
Summary of the invention
The present invention proposes a kind of networking telephone redialing method and system, and solve the user demand problem of networking telephone callback service, use safety, call completing rate is high.
In order to achieve the above object, the technical scheme that the present invention takes is: a kind of networking telephone redialing method, comprises the following steps:
(1) client sends call request signal to dispatch server;
(2) dispatch server filters after receiving signal, prevents improper attack;
(3) dispatch server judges whether to belong to legitimate call;
(4) what dispatch server selected corresponding operator according to the number of callee lands the concurrent number of delivering letters of server, and the server that lands links gateway device after receiving signal;
(5) gateway device calls out the user made a call at first, and after connecting phone, gateway device is responsible for calling out called subscriber, both sides' normal talking;
(6) both sides' any one party is hung up the telephone, and client sends hang-up signal to dispatch server, and server is to landing server transmission hang-up signal, and the server that lands links gateway device after receiving signal, and gateway device sends hang-up signal;
(7) dispatch server statistics duration of call expense, end of conversation.
Further, the server cluster architecture technology of described dispatch server working load equilibrium.
Further, step (2) described filter method is:
(201) subsidiary arbitrary string when client sends call request signal to dispatch server, then does md5 encryption, then sends to dispatch server;
(202) dispatch server adds after receiving parameter that the character string md5 appointed encrypts, and compares the value after encryption, determines whether normal request.
Further, each client uses different user keys.
Further, described in step (3), the Rule of judgment of legitimate call comprises: whether whether user have expense, allow to call out, whether what call out is non-method number.
Apply the networking telephone ACCB of above-mentioned redialing method, comprising: client, dispatch server, described client connects described dispatch server by network, and described dispatch server is provided with filter and judgment means; Described filter is used for the signal of filtering client, prevents improper attack; Described judgment means is for judging whether the number of callee belongs to legitimate call; Described dispatch server connects the server that lands of each operator by network, described in land server and connect the gateway device of operator.
Further, described dispatch server is the server cluster of load balancing.
Further, described filter comprises the md5 encrypting module of client and the md5 encrypting module of server end.
Further, described client is provided with user key module.
Further, described judgment means comprises calling party's judge module and callee's judge module, and described calling party's judge module is for judging whether user has expense, whether allowing calling; Described callee's judge module is for judging whether callee is non-method number.
Beneficial effect of the present invention is: the present invention solves the user demand problem of networking telephone callback service, by setting up the server cluster framework of load balancing, solve concurrency and too high problem and networking telephone ACCB can not just there will be unstable problem, improve speech quality, make network callback service reach the standard of good service.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further.
Structure of the present invention as shown in Figure 1, comprises client, dispatch server, and described client connects described dispatch server by network, and described dispatch server is provided with filter and judgment means; Described filter is used for the signal of filtering client, prevents improper attack; Described judgment means is for judging whether the number of callee belongs to legitimate call; Described dispatch server connects the server that lands of each operator by network, described in land server and connect the gateway device of operator.Wherein, dispatch server is the server cluster of load balancing.
Concrete use step is as follows:
Network system of the present invention is that the Session Initiation Protocol of main flow Network Based communicates, communication substantially flow process is as follows: client downloads is also installed mobile phone app-> and to be registered and login account-> client sends ajax signal-> server to dispatch server receives signal and first determine whether the request that normal client is initiated later, prevent improper attack, a large amount of spurious requests, filtering technique means are: (write after obtaining all RequestQueryString after request in corresponding map structure, then by alphabet size sequence, whether finally calculate sign according to md5 algorithm is normal request, shuffle for preventing many cover systems, herein every cover system introduce independently appkey to be used as the secret key of user, after have modified appkey at any time, verification algorithm also can change according to amendment), afterwards according to condition judgment (such as: whether user has expense, whether permission is called out, whether what call out is non-method number, such as 10086,110, bank, public security organs some do not allow the number called out)-> screening server lands server according to the sip set in advance: < note: the server > herein provided for telecommunication department sends after sip calling invoke signal-> upper layer device receives sip signal, link gateway device-> gateway device call out the initial calling party of user-> made a call at first and is connected phone-> gateway device and be responsible for the calling called subscriber-> both sides normal talking-> both sides any one party-> that hangs up the telephone and send ajax signal-> server to upper strata gateway transmission invoke hang-up signal-> server statistics duration of call expense-> end of conversation to server.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
