In a code division multiple access mobile communication system, a communication signal is modulated and multiplexed with different diffusion codes and is used in data communication between a base station (30) and each of mobile units (40, 41, 42). The communication signal is a time division multiple
In a code division multiple access mobile communication system, a communication signal is modulated and multiplexed with different diffusion codes and is used in data communication between a base station (30) and each of mobile units (40, 41, 42). The communication signal is a time division multiplex signal with a repeated frame having a plurality of time slots (TS0, TS1, TS2) assigned to different radio channels, respectively. A slot synchronous signal is produced in accordance with a reference clock signal of a global positioning system. The time slots are synchronized between the base station and each of the mobile units in accordance with the slot synchronous signal.

The time slots are synchronized between the base station and each of the mobile units in accordance with the slot synchronous signal. o given resources of a packet-oriented communication network, comprising the steps of: allocating a first and at least a second ring buffer, each respectively comprising annularly chained memories, to the network terminal units, said chained memories being successively cyclically readable; initially for at least one connection setup initiated by at least one of the network terminal units, allocating respectively requested partial resources to the at least one network terminal unit by entry of corresponding access authorizations into the annularly chained memories of either the first or the second ring buffer so that access of the respective network terminal units onto the resources of the communication network is controlled according to the respectively read access authorizations by means of cyclical sampling of the memories of the ring buffer comprising the entered access authorizations; given every change of the corresponding access authorizations or given a further request or release of partial resources by at least one of the network terminal units, determining anew the access authorizations and entering updated access authorizations into the annularly chained memories of the first or second ring buffer not currently used for the control of the access; and following the entering, controlling the access onto the resources of the communication network according to the respectively read access authorizations by means of the cyclical sampling of the updated first or second ring buffer. 2. The method according to claim 1, including the further steps of: in the connection setup, determining a delay of the accesses of the network terminal units to the allocated partial communication network resources by occupation of the annularly chained memories; and not exceeding the determined delays during access to the allocated partial communication network resources. 3. The method according to claim 1, wherein without an entered access authorization, the annularly chained memories are occupied with a further item of information not related to the access authorizations and which is individual to the network terminal unit. 4. The method according to claim 1, wherein the access authorizations of the network terminal units are entered into the annularly chained memories in such a way that accesses to the allocated partial communication network resources are optimized according to predetermined criteria. 5. The method according to claim 4, wherein the predetermined criterion represents a minimum delay of the accesses of the network units to the allocated partial communication network resources. 6. The method according to claim 1, wherein the annularly chained memories are sampled with a packet pulse of the packet-oriented communication network, and the access authorizations are read out. 7. The method according to claim 1, wherein a number of the annularly chained memories is determined dependent on a predetermined scope of the resources of the packet-oriented communication network and on an arbitrarily predeterminable scope of the partial communication network resources. 8. The method according to claim 1, wherein the packet-oriented communication network is realized by a communication network designed according to an asynchronous transfer mode. 9. The method according to claim 1, wherein the predetermined resources of the packet-oriented communication network are represented by transmission capacity of at least one of wire-bound, optical, and wireless transmission paths in a feeder network of the packet-oriented communication network.
