Company network using time slot reuse
First Claim
1. Arrangement for a communication system which on the one hand comprises a number of company nodes which operate with a master function and are each arranged to cover a part area in a common geographical area, for example within a company, in a factory, hospital, etc., and on the other hand is arranged to allow a number of customer nodes operating with slave functions to be capable of being activated and deactivated for telecommunication and/or data communication within the common geographical area, the system being assigned frequencies within a selected frequency band range and operating with a time gap (slot) function, which assigns the nodes time gaps (slots) within the respective part area, and a synchronizing function (for time and frequency), for example brought about by means of a synchronizing node, one of said company nodes or a GPS function, and also comprising a database accessible to the respective company node, characterized in that the company nodes are arranged to operate with coordinated time gaps (slots) and with common frequencies appearing therein which shift simultaneously according to the hopping system used, and in that the various company nodes are in this way arranged to bring about a common identity with regard to the respective mobile customer node and thus eliminate for the latter the requirement for handshaking in order to be taken over by the respective new company node when the customer node passes between part areas within the common area.

Abstract
An arrangement and a device comprises a mobile data and communication network within a predetermined geographical area. The device operates with first and second functions that can consist of, for example, company and/or customers functions and communication and/or slave functions respectively. Two or more units in the first function are synchronized with each other as regards time and frequency in order to act, from the point of view of connection and disconnection functions, as a common first unit for second units that carry out the second function. Time consuming handshaking procedures are then avoided for the second units when these one'"'"'s are moving and shifting between part areas of said predetermined area and the total system will operate rapidly in this respect.

- 4. A device in the form of a mobile data and communication network within a predetermined geographical area, for example within a company, factory, hospital, etc, and working with first functions, for example in the form of base station and/or master functions and second functions, for example in the form of communication functions and/or data functions, established by means of fixed and/or movable mobile units and/or nodes, characterized in that two or more units in the first function are synchronized with each other as regards time and frequency in order to act, from the point of view of connection and disconnection functions, as a common first unit for second units that carry out the second function, whereby handshaking procedures are avoided when the second units are moving or shifting between part areas in said predetermined geographical area.

23. A device for a geographical area provided with a mobile internal telecommunications and/or data network in which there is a base station/master function, here called a first function, and a mobile/slave function, here called a second function, characterized in that a mobile unit that enters the area achieves synchronization to the network, that the first and second functions set up query and response functions, that the mobile units perform direction functions within the geographical area, that in the event of movement of the mobile unit within the area, updating of this is carried out in the first function, that an interest or need function registered by the mobile unit can be processed in the first function, and that any payment function associated with the interest or need function can be implemented between the first and second functions.
