Description
Technical field
The method that the present invention relates to the call agent device based on voip technology and use this device to dial and receive calls.
Background technology
Business people needs between each big city or internal and overseas, to run at home continually, needs in this course to keep whenever and wherever possible and extraneous liaison.In mobile communication, when the place that user communicates exceeds the coverage of its former address location register (home location register, HLR), communication is now called roaming communication.Roaming can be divided into National roaming and international roaming by region, and the network using by communication can be divided into roaming and internet roaming in net.Current, the main communication mode that mobile subscriber adopts in roam procedure comprises voice communication, short message and Email.Because the real-time of voice communication is best, first choice of business people.Next described communication, if without specified otherwise, all refers to voice communication.
In existing communication mode, PSTN wire communication cannot provide roaming service, and mobile communication can provide roaming service.For National roaming, its expense is lower.If user selects the tariff package that monthly rent is more expensive, the communication cost of National roaming can be accomplished with local communication suitable.Yet for international roaming, owing to relating to the settling problems between operator and need to use proprietary international communication circuit, its post and telecommunication tariff is very high.For example, the 3G subscription of CHINAUNICOM, the rate of answering domestic call while roaming into Zimbabwe are 5.86 yuan of per minute kinds.Communication cost while roaming in order to save, after user has arrived roaming place, generally can buy the Mobile Directory Number of a new roaming place, by this new digit, communicates by letter with domestic and roaming place native client.There is following problem in this mode: 1, user need to inform new digit all friends associated with it (comprising its client) before.This point can accomplish, but quite difficult.Before receiving user's new digit, these friends can contact him/her by the domestic telephone number of this user, cause and do not contact.For before those with this user without the potential customers that contact, may contact again afterwards this user, this user cannot notify this part people.And this user's friend uses the new digit of its roaming place to contact this user need to bear high international communication expense.2, when this user from abroad get back to domestic, he/her need to notify all clients he/her come back home, please by domestic call number, contact with it.If user goes on business through the different country that is everlasting, friend is difficult to accept to the behavior meeting of its this frequent replacing telephone number.
In order to solve the too high problem of communication cost of roaming particularly international roaming, someone proposes the solution of a class based on VoIP (Voiceover Internet Protocol, the i.e. networking telephone) technology.The way of this scheme is: user is to the voip phone number that can accept incoming call of VoIP operator application, the fixed telephone number that this number is subscriber's local.User, from National roaming is gone abroad, calls out and shifts in belonging area network gateway registration, and the incoming call of its ownership place telephone number is transferred to voip phone number; At voip gateway place register call, shift simultaneously, the incoming call of its voip phone number is transferred to the new digit of external roaming place.After this, this user's friend to call out this user's flow process as follows: 1, friend calling party's ownership place telephone number; 2, this is called out and arrives belonging area network gateway, and the latter forwards the call to the user's voip phone number; 3, this is called out and arrives voip gateway, and the latter forwards the call to the telephone number of the external roaming place of user; 4, access success is set up.
In such scheme, as the user's of caller friend, only need bear the communication cost of calling party's ownership place number, be local communication expense, conventionally very low.The expense that need to bear as called user has: 1, the incoming call of ownership place number is transferred to the communication cost of VoIP number, is local communication expense; 2, the incoming call of voip phone number is transferred to the communication cost of external roaming place telephone number, is international communication expense, but owing to having adopted voip technology, general and local communication appropriate litigation fees; 3, user answers the communication cost of the incoming call of roaming place telephone number, for the called communication cost in this locality, generally free.This scheme can overcome the shortcoming of the first scheme, but also has following problem:
1,, for the user to all parts of the world provides service, VoIP operator need to have telephone number resource, each department, the Bing various countries configuration voip gateway of a large amount of each department, various countries.
VoIP operator will meet above condition, is almost impossible, and reason has two.One, configure so many voip gateway, have so many telephone number resource, must have huge financial support; Its two, even if there is such fund in VoIP operator, but it differs surely in various countries' operation.Take China as example, and Chinese Government has made laws and has forbidden the VoIP business (forbid China arrange voip gateway) of commercial use, more impossiblely to VoIP operator, provides the resource of telephone number all over China.Like this, VoIP operator will the loss of China this have the global biggest market of maximum mobile communication subscribers.
Here explain in passing why VoIP operator needs to have the telephone number resource of various places, global various countries.Suppose that VoIP operator does not have the telephone number resource of subscriber's local, can only provide the telephone number in strange land as voip phone number to user.Like this, the communication cost that the incoming call of user ascription area number is transferred to voip phone number is national distance communication cost, generally higher.
2, this scheme can only reduce the expense that user receives calls in roaming place, and the high expense of dialing other the regional phone generation except roaming place for user in roaming place is of no avail.
Summary of the invention
Object of the present invention is just to provide a kind of call agent device based on voip technology, use this device in roaming place, dial and the expense that receives calls low, be easy to realize, and it is simple in structure, acquisition cost is low.
The present invention realizes its goal of the invention, and the technical scheme adopting is a kind of call agent device based on voip technology, comprising:
Phone module: the control of controlled module, transfer information between telephone network and control module;
VoIP client modules one and VoIP client modules two: the control of controlled module, transfer information between control module and VoIP server;
Control module: control phone module, VoIP client modules one and VoIP client modules two, with complete communication link foundation, safeguard and release, and in transfer information between phone module and VoIP client modules one and between VoIP client modules one and VoIP client modules two.
The first method of using said apparatus to dial and receive calls, comprises the following steps:
A.1 described agent apparatus user registers its roaming place telephone number in control module, the main telephone number of its ownership place is configured on phone module simultaneously;
A.2 agent apparatus user or other users call out main telephone number;
A.3 phone module is received this calling, and control module judges whether the incoming call of phone module is the roaming place telephone number of registering, and if so, is judged to be agent apparatus user wish and calls by this agent apparatus thereon, proceeds to A.8 step; Otherwise, be judged to be other user and want Call Agent device users;
A.4 control module is controlled phone module and wouldn't be connected this calling, and controls VoIP client modules one and call out roaming place telephone number by VoIP server;
A.5 agent apparatus user connects this calling receive the calling of VoIP server in roaming place after;
A.6VoIP client modules one notice control module, sets up with the calling of roaming place telephone number; Control module is controlled phone module and is connected before this incoming call of access failure temporarily;

B.15 EO.
In said method, B.1 the inferior telephone number in step is user's telephone number at home.This number is mainly used in calling in roaming place, at home, user not (or seldom) by this number and extraneous contact, this number is seldom known to the external world.
In said method, B.1 the main telephone number in step refers to that user often uses roaming place toll free number in roaming place abroad.
Above-mentioned second method is mainly used in user when international roaming, in roaming place, call, basic identical with the operation of calling that first method provides, difference is: while 1, calling, user is except using main telephone number, also can use other any telephone numbers of roaming place, if user uses main telephone number call, call agent device not the identity of authentication of users just can carry out subsequent voice calls flow process; Otherwise user needs input validation information, until authentication by after can carry out subsequent voice calls flow process.2, first method requires user to have fixing external roaming place telephone number, and second method is without this requirement.Compare with first method, second method is more flexible.First method is identical with the communication expense that second method is called generation, is the expense of 2 sections of VOIP communication links.
Compared with prior art, the invention has the beneficial effects as follows:
One, communications cost is low: use call agent device of the present invention, according to above two kinds of methods, device users can be realized roaming place abroad and answer and call, but can not produce high international roaming expense, the communication cost producing is only the expense of one and two VoIP communication link.The general appropriate litigation fees of calling with this locality of expense of VoIP communication.In addition, communication means provided by the invention does not affect the communication cost with other user of agent apparatus telex network.Other user, as caller, during Call Agent device users, only need bear the expense of the domestic ownership place telephone number of Call Agent user; Other user when called, only need bear the expense answering the call by telephone network.
Two, call agent device to realize cost low: the device of this aspect comprises two VoIP client modules, a control module and a phone module, has two kinds of implementation methods.The first, the method with pure software on smart mobile phone realizes.Smart mobile phone itself is exactly a phone module, and supports VoIP communication protocol, can realize the function of VoIP client modules; In addition, most smart mobile phone has WiFi function, easily accessing Internet.The second, the ordinary telephone set of take increases corresponding hardware as basis to be realized.Need the hardware increasing to comprise: central control equipment and VoIP client modules equipment.The cost of these equipment is low.In addition, the second method claimed apparatus user based on device of the present invention is to one telephone number of phone module configuration.Because user does not communicate by letter with extraneous by this number, so this number is only accepted incoming call.That user can receive calls freely to telephone operator application, call is very expensive, without the telephone number of monthly rental as inferior telephone number.
Three, meet the legal requirements: 1, two client modules in call agent device of the present invention are through the Internet and VoIP server communication, and the deployed position no requirement (NR) of the present invention to VoIP server, so just can avoid the current law national with some to disagree.Take China as example, because Chinese Government has made laws, forbid within Chinese territory, disposing VoIP server, get on very well in theory, there is no legal VoIP server within Chinese territory, agent apparatus user can select VoIP server to be positioned at China VoIP operator overseas.2, the present invention does not require that device users has the voip phone number of phone incoming call function to the application of VoIP operator.
Four, easy to use: the communication custom that does not change other user who communicates by letter with agent apparatus with the method receiving calls of dialing provided by the invention.
Certainly, compare with not adopting the existing International Roaming Plan of voip technology, the present invention also has inferior position: existing mobile communication, when carrying out international roaming, all adopts proprietary telecommunication line to transmit communication data, exchanged form is circuit switching, and its service quality is high, time delay is little, without delay variation.Adopt method of the present invention, user dials in roaming place and the Shi Junxu that receives calls transmits communication data through VoIP link.VoIP link is actually the Internetwork link based on packet switch, its service quality can decline, time the increase of postponing a meeting or conference, there will be delay variation.But along with the increase of internet communication capacity and the development of voip technology, the problems referred to above can be improved gradually; According to ITU (International Telecommunications Union) technical standard, in the near future, all Speech Communications all will adopt voip technology.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
