Description
Technical field
The present invention relates to based on the call agent equipment of voip technology and the method for using this equipment to dial and receive calls.
Background technology
The business people needs to run between each big city or internal and overseas at home continually, needs in this course to keep the liaison with the external world whenever and wherever possible.In mobile communication, when the place that the user communicates exceeded the coverage of its former address location register (home location register, HLR), the communication of this moment was called roaming communication.Roaming can be divided into National roaming and international roaming by the region, and the network that uses by communication can be divided into roaming and internet roaming in net.Current, the main communication mode that the 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 the business people.Next described communication, if without specified otherwise, all finger speech sound communication.
In existing communication mode, the PSTN wire communication can't provide roaming service, and mobile communication can provide roaming service.For National roaming, its expense is lower.If the user selects the more expensive tariff package of monthly rent, the communication cost of National roaming can be accomplished with local communication suitable.Yet for international roaming, because the settling problems and the needs that relate between operator 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 when roaming into Zimbabwe are 5.86 yuan of per minute kinds.Communication cost when roaming in order to save after the user has arrived the roaming place, generally can be bought the Mobile Directory Number of a new roaming place, communicates by letter with domestic and roaming place native client with this new digit.There is following problem in this mode: 1, the 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 still contact with it by the domestic telephone number of this user, cause not contact.For before those with this user without the potential customers that contact, may contact again afterwards this user, this user can't 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 after, he/her need to notify all friends he/her come back home, please contact with it by the domestic call number.If the user goes on business through the different country that is everlasting, friend is difficult to accept to its behavior meeting of often changing telephone number.
In order to solve the too high problem of the communication cost of roaming particularly international roaming, someone proposes a class based on the solution of VoIP (Voice overInternet Protocol, the i.e. networking telephone) technology.The way of this scheme is: the user is to the voip phone number that can accept incoming call of VoIP operator's application, and this number is the fixed telephone number of subscriber's local.The user from National roaming abroad before, call out in the belonging area network gateway registration and shift, the incoming call of its ownership place telephone number is transferred to the voip phone number; In voip gateway place's register call transfer, the incoming call of its voip phone number is transferred to the new digit of external roaming place simultaneously.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 the 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, only need bear the communication cost of calling party's ownership place number as the user's of caller friend, be the local communication expense, usually very low.The expense that need to bear as called user comprises: 1, the incoming call of ownership place number is transferred to the communication cost of VoIP number, is the local communication expense; 2, the incoming call of voip phone number is transferred to the communication cost of external roaming place telephone number, is the international communication expense, but owing to having adopted voip technology, general and local communication appropriate litigation fees; 3, the user answers the communication cost of the incoming call of roaming place telephone number, and is 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 the telephone number resource of a large amount of each department, various countries, and at each department, various countries configuration voip gateway.
VoIP operator will satisfy above condition, is almost impossible, and reason has two.One will configure so many voip gateway, have so many telephone number resource, and huge financial support must be arranged; Its two, even there is such fund in VoIP operator, but it differs surely in various countries' operation.Take China as example, Chinese Government's VoIP business of forbidding commercial use (namely forbidding arranging voip gateway at China) of having made laws more impossiblely provides the resource of telephone number all over China to VoIP operator.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 the voip phone number to the user.Like this, the communication cost that the incoming call of user ascription area number is transferred to the voip phone number is the national distance communication cost, and is generally higher.
2, this scheme can only reduce the expense that the user receives calls in the roaming place, and the high expense of dialing other the regional phone generation except the roaming place for the user in the roaming place is of no avail.
Summary of the invention
