Description

Virtual telephony

The present invention relates to the telecommunication technology field.

Existing program controlled telephone has the characteristics of the position of fixed number of a phone and basic fixed, can squeeze into and can get.People can be at any time with extraneous contact, interchange by phone.In addition, stored-program control exchange can provide the calling transfer service to the program controlled telephone user, if the user is not other and elsewhere at the telephone set of oneself, can utilize this service to make to make a call the place of getting to the user place of this Subscriber Number to answer, the user just can not miss phone like this, and other people can can't not get in touch on his telephone set side because of this user yet.The weak point of this service is if the user has registered calling transfer, and other people just can't utilize this telephone receiving incoming call (promptly all phones all can't be squeezed into this phone), and this phone just can only be got and can not squeeze into, and the function of phone has just reduced half.

In addition, the hardware equipped of existing telephone (as telephone set, communication line, user circuit board etc.) expense height, a phone is installed is spent several thousand yuan, can not satisfy the requirement of everybody phone at present, also waste huge (as an office people more than ten is arranged, adorned ten multi-section phones) and need not even accomplished everybody phone.

The purpose of this invention is to provide a kind of expense cheap, can make full use of existing telephone, user any user phone just get to which, do not have true body but new-type phone---the virtual telephony that can use.

Content of the present invention is such: in program controlled system, set up legal, (not being spacing) that can use, need not supporting user's hardware (as telephone set, electric wire, user circuit board etc.), do not belong to the telephone number of a certain fixed telephone, and utilize the call forwarding function of stored-program control exchange, answer making a call on the predetermined plain old telephone of transferring to of this telephone number, realize that it answers the calling function.

The phone of above-mentioned telephone number representative is virtual telephony of the present invention (also claiming personal call), is characterized in that this phone does not have supporting corresponding user's hardware device, need utilize calling transfer (or " walking with me the ") function of stored-program control exchange could use, can only squeeze into and can't get (because of not having user's hardware and terminal).

Virtual telephony of the present invention is actually the telephone number that does not have user's hardware and terminal, be a kind of invisible " phone " that is present in the SPC digital switch software (program), it is compared with existing phone tangible, necessary being, has significant advantage.At first be that " installation " expense is very cheap, even need not to spend (only need in the relevant procedures of switch the input telephone number and be provided with related parameter just can), common personage affords, affords to use, and energy horse back " installation " after the application, and the user just can use at once.Next is motor-driven efficient, and the user is at which, and which user's phone just gets to, and existing telephone is fully used, and the telephoner can be because of not can not find the people's game of shuttlecocks that will look for yet.For example certain user goes to work in first unit today, hold a post and be transferred to company B tomorrow, this user just need not to change the personal telephone number (being virtual phone number) of oneself, and the destination number that only need change in the calling transfer registration gets final product, no matter the user where, personal number can both normally use (even available all one's life), can accomplish really that telephone number that the expert foretells, desirable belongs to the individual and do not belong to intelligence communication requirement tomorrow of certain telephone set.The telephone number that will change the individual in addition is also easier, because can not have influence on other people.Also more flexible in the use, convenient, use is bigger.For example certain user does not think that others gets in touch with him or bothers him, and he just can use the absence service or the interruption-free service of stored-program control exchange, and he do can the chamber phone and the family phone still can normally use for other people.If a people has the multi-section virtual telephony simultaneously, use more convenient, he can tell different virtual phone numbers different people to use, if do not want with someone or certain class people contact, only need stop using corresponding virtual telephony to get final product, and other people still can be normally with his contact.And for example someone has two virtual telephonies, and one one is used for work, and one one is used for private life's (as with household's contact), and the thing that if he do not think in the work is tired of him, as long as he closes this virtual telephony (promptly registering the interruption-free service).Virtual telephony also has an important feature, promptly has function of keeping secret, and no matter when, the stranger will can not know the machine master at which, and if use plain old telephone, other people can know from telephone number that the Position Approximate of this phone or user (and dwelling) are probably at which.Along with the raise-position of telephone number, with respect to the population total amount, we can say that virtual telephony is endless, can satisfy everyone one one demand fully, plain old telephone is owing to the restriction that is subjected to equipment, fund, hardware then is difficult to satisfy the demands.

The present invention can realize like this: remove the hardware (as telephone set, cable line etc.) that (or disconnection) opened the program controlled telephone of use, the telephone number of remaining correspondence is a virtual telephony; Certainly the best way is to set up legally (promptly can not follow other phone repeated code in program controlled system or continuous computer, meet the requirement of distributing telephone numbers) telephone number and do not give the supporting related hardware of this number (as cable line, telephone set, user circuit board etc.), as long as few expense and time of cost just can be opened a virtual telephony, the user was as long as register call transfer service (being purpose phone number) just can use immediately after " installation " gave the user like this.

Virtual telephony is distributed telephone numbers, and (program of distributing telephone numbers and class of operation are distributed telephone numbers like existing telephone, but lacked user's hardware components and with the work of the relevant software section of user's hardware) when the user need use afterwards, can carry out calling transfer (also claiming " walking ") registration by the operator or the operator of stored-program control exchange (or relevant device) with me, initial number (be user's virtual phone number or corresponding equipment number) and destination number (be the telephone number of destination or corresponding equipment number) are registered in (and the sign indicating number that imposes a condition in the corresponding call transfer table (or user data auxiliary storage), be generally unconditional branch), its enrollment process is the same with the calling transfer process of the existing program controlled telephone of registration basically, and for example available following OM orders and is provided with or changes in SOPHO S2500 program controlled system, cancellation calling transfer relation: CHCALF;＜initial number) _S/r[,＜destination number 〉].Also can import the corresponding command in addition to stored-program control exchange, giving the virtual telephony user far controls power (general stored-program control exchange all has this function, for example in the S1240 switching system, RMCTR=SUBSCTF is set), make the user calling transfer (as on-hook behind group special service number+personal telephone number+password) is set, on the telephone set of transferring to user's appointment of making a call user's virtual phone number (being personal telephone number) by plain old telephone oneself.Can import by the operator with reference to corresponding stored-program control exchange operation instructions with professional relevant program of virtual telephony and order, also can require switch manufacturer to provide, install, manufacturer can satisfy the various specification requirements (because the program, order, the function that are increased are very simple for manufacturer) in virtual telephony setting, the use.

The present invention is applicable to the various SPC digital switches of (or " walking with me the ") function that has calling transfer.
