DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates primarily to a method of connecting selectively stationary subscriber apparatus to a mobile subscriber apparatus through a telephone subscriber exchange which includes a telephone switch function or switchboard function, by means of which incoming calls can be transferred and which is connected to a number of stationary subscriber apparatus included in the telephony system and a number of mobile subscriber apparatus, such as taxi-carried telephone apparatus, which also form part of said system, and computer apparatus included in the switchboard, in response to a call from a stationary subscriber apparatus to a telephone number relating to a plurality of mobile subscriber apparatus, said number being referred to hereinafter as the "group number".
The invention also relates to a system in which the system components coact and are mutually connected in a manner to operate in accordance with the inventive method.
Reference is made in the following description to "subscriber apparatus which belong to a stationary system" or "stationary subscriber apparatus" and it will be understood that this category of apparatus does not solely include those apparatus which can be connected to a telephone exchange or switchboard with the aid of physical telephone lines, but also to other forms of immobile (or mobile) telephones. It is significant to the invention, however, that the geographical area or location of a particular stationary telephone apparatus and of the person using said apparatus can be readily determined.
Reference is also made in the following description to "subscriber apparatus which belongs to the mobile system" or to "mobile telephone apparatus" By this expression is meant a subscriber apparatus which is installed in a mobile unit, such as a taxi, express delivery vehicle, a public service vehicle and the like, which carry mobile telephone equipment and with which it is possible to establish the exact geographical location of the mobile unit concerned or the exact geographical area in which said unit is located in a positive fashion.
In this latter case, it may concern a "stationarily connected subscriber apparatus" when the mobile subscriber apparatus has informed that it receives calls at a particular place, at the subscriber apparatus of a taxi station or the like.
It will be obvious to the technician skilled in this field which type of subscriber apparatus shall be used within the two aforesaid categories.
It is also stated in the description that the "subscriber apparatus" are active in making calls or leaving messages, although it will be understood that each such function of a subscriber apparatus is initiated and effected by the person operating the subscriber apparatus concerned.
When one of the stationary subscriber apparatus belonging to the system establishes a connection to a "group number", it will be understood that the "group number" selected in this case is not served directly by a number of mobile subscriber apparatus, which belongs to the earlier known art, but that before the call is connected a particular mobile telephone apparatus selected according to certain merits.
Furthermore, the term "telephone exchange" or "switchboard function" as used here, does not only indicate telephone stations but also subscriber exchanges and the like, although the telephone switchboard used must have a built-in so-called call "transfer function" capable of being activated and influenced by computer equipment.
BACKGROUND ART
With regard to the significant properties and characteristic features of the present invention, several types of telephone exchanges or telephone stations are known to the art which fulfill the aforesaid conditions that are fundamental to the function of the present invention.
The present invention is based on the use of a telephone subscribes exchange incorporating a switchboard function to as a call transfer or "transfer function".
The call transfer function as such is-earlier known and is included in many telephone switchboards,
