Claim 10

The apparatus of claim 7 wherein the access requests of which indications thereof are received at said access request receiver and prioritizer include data fields identifying the access request to be for the communication of informational data.

Claim 11

The apparatus of claim 7 wherein the access requests of which indications thereof are received at said access request receiver and prioritizer data fields identifying the access request to be for the communication of background noise data.

Claim 12

The apparatus of claim 7 wherein said access request receiver and prioritizer prioritizes access requests for the allocation of the time slots for the communication of informational data with a higher priority level than access requests for the allocation of the time slots for the communication of background noise data.

Claim 13

The apparatus of claim 10 wherein said access request receiver and prioritizer further comprises a memory device for storing a queue containing access requests ranked by priority levels.

Claim 14

The apparatus of claim 11 wherein said time slot assignor further assigns available time slots to the selected pairs of sending and receiving stations to which access requests associated therewith exhibit highest priority levels.

Claim 15

The apparatus of claim 12 wherein said time slot assignor further allocates available time slots to the selected pairs of sending and receiving stations which exhibit lower priority levels only subsequent to assignation of time slots responsive to every access request exhibiting a higher priority level.

Claim 16

The apparatus of claim 7 wherein the at least one carrier comprises a plurality of carriers and wherein said apparatus further comprises: a signal quality determiner for determining signal quality levels on each of the plurality of carriers and for associating signal quality levels with the time slots defined thereon; and, wherein said time slot assignor is further coupled to receive indications of the signal quality levels determined by said signal quality determiner and assignations made thereat are further responsive thereto.

Claim 17

In a TDMA communication system in which data is transmitted in bursts during a selected number of time slots defined upon at least one carrier between pairs of sending and receiving stations, groups of successive time slots forming frames, an improvement of apparatus for initiating an access request for requesting allocation of time slots for communication, selectively, of informational data and background noise data between a selected sending station and a selected receiving station, the background noise data and the information data together combinable at the selected receiving station to form a receive signal, said apparatus comprising: a request detector and formatter coupled to receive indications of a request to initiate communications between the selected sending station and the selected receiving station, said request detector and formatter for setting a data field to a first value when the indications of the request are for the allocation of time slots for the communication of background noise data and to a second value when the indications of the request are for the allocation of time slots for the communication of information data; and an access request generator coupled to said request detector and formatter to receive the data field set thereat, said access request generator for generating an access request message including a value representative of the data field set by said request detector and formatter.

Claim 18

In a TDMA communication system in which data is transmitted in bursts during a selected number of time slots defined upon at least one carrier between pairs of sending and receiving stations, groups of successive time slots forming frames, an improvement of apparatus for initiating an access request for requesting allocation of time slots for communication, selectively, of informational data and background noise data between a selected sending station and a selected receiving station, the background noise data and the information data together combinable at the selected receiving station to form a receive signal, said apparatus comprising: a request detector and formatter coupled to receive indications of a request to initiate communications between the selected sending station and the selected receiving station, said request detector and formatter for setting a data field to a first value when the indications of the request are for the allocation of time slots for the communication of background noise data and to a second value when the indications of the request are for the allocation of time slots for the communication of information data; and an access request generator coupled to said request detector and formatter to receive the data field set thereat, said access request generator for generating an access request message including a value representative of the data field set by said request detector and formatter.
