3. The terminal calling system as claimed in claim 1, wherein said mobile network exchange and said fixed network exchange stop calling to the other terminals in said group comprising a combination of said mobile terminals and said fixed terminals, in accordance with the group data in said database, when one of said called group terminals is answered.

5. The terminal calling system as claimed in claim 1, wherein said mobile network exchange and said fixed network exchange have, as subscriber data, common group telephone numbers in the mobile terminals and fixed terminals comprising said groups, and access the group data recorded in said database by means of said group telephone numbers.

2. Terminal calling system in an integrated exchange network, which uniformly controls mobile terminals and fixed terminals, comprising:

a composite network exchange which controls connections with both mobile terminals and fixed terminals, and

a database which is accessed by said integrated network exchange, said database recording data about groups comprising a combination of said mobile terminals and said fixed terminals,

said integrated network exchange uniformly calling all or some of the terminals within one group of said groups comprising a combination of said mobile terminals and said fixed terminals, in accordance with the group data of said database, all of said calling terminals being uniformly called prior to call completion with any of said called terminals, the group comprising a combination of mobile terminals and fixed terminals, which are recorded in said database, comprises group telephones, said group telephones include group representative subscriber telephones which can receive group call services when the subscriber receives an incoming call, and group elementary subscriber telephones which can receive group calls but which cannot receive group call services with respect to incoming calls made personally, and access the group data recorded in said database by means of the telephone numbers of said group representative subscribers.

4. The terminal calling system as claimed in claim 2, wherein said integrated network exchange stops calling to the other terminals in said group comprising a combination of said mobile terminals and said fixed terminals, in accordance with the group data of said database, when one of said called group terminals is answered.

6. The terminal calling system as claimed in claim 2, wherein said integrated network exchange has, as subscriber data, common group telephone numbers in the mobile terminals and the fixed terminals comprising said group, and accesses the group data recorded in said database by means of said group telephone numbers.

7. Terminal change-over system in a composite communications network including mobile terminals and fixed terminals, comprising:

a mobile network exchange which controls connections with mobile terminals,

a fixed network exchange which controls connections with fixed terminals, and

a database which is accessed in common by said mobile network exchange and said fixed network exchange,

said database records data about groups comprising a combination of said mobile terminals and said fixed terminals which are the object of a mutual change-over,

said mobile network exchange and said fixed network exchange change over and connect the mobile terminals or the fixed terminals, during a telephone conversation, to the fixed terminals or the mobile terminals comprising said combination, in accordance with the group data of the mobile terminals and the fixed terminals in said database, without interrupting said telephone conversation.

9. The terminal change-over system as claimed in claim 7, wherein said mobile network exchange and said fixed network exchange notify of a call-hold in said group to said database when a subscriber of said group holds a call, access said database and search for the held call in said group when a subscriber in said group performs reply processing of the held call, and change over and connect said call, which is on hold, inside the group, from the subscriber number of the subscriber who is on hold, obtained by means of said search, to said hold reply call.

8. A terminal change-over system in an integrated exchange network which uniformly controls mobile terminals and fixed terminals, comprising:

an integrated network exchange which controls connections with both mobile terminals and fixed terminals, and

a database which is accessed by said integrated network exchange,

said database records data about groups comprising a combination of said mobile terminals and said fixed terminals which are the object of a mutual change-over, said integrated network changes over and connects the mobile terminals or fixed terminals, during telephone conversation, to the fixed terminals or the mobile terminals comprising said combination, in accordance with the group data of the mobile terminals and fixed terminals in said database, without interrupting said telephone conversation.

10. Terminal change-over system as claimed in claim 8, wherein said integrated network exchange notifies said database of a call-hold in said group to said database when a subscriber of said group holds a call, accesses said database and searches for the held call in said group when a subscriber in said group performs reply processing of the held call, and changes over and connects said call, which is on hold, inside the group, from the subscriber number of the subscriber who is on hold, obtained by means of said search, to said hold reply call.
