1. A method for assigning channels in a spatial division multiple access communication network, the network including a plurality of conventional channels some of which are configurable to be shared concurrently by plural subscribers as spatial channels, the method comprising:
- a. determining if a new subscriber is to be added to the network;
b. determining if a conventional channel is available, and if so, assigning the new subscriber to the available conventional channel;
c. if no conventional channel is available, determining an acceptable combination of subscribers from the existing subscribers and not including the new subscriber to share a channel as spatial channels;
d. reassigning the existing subscribers to share the channel creating a spatial channel thereby freeing at least one conventional channel; and
e. assigning the new subscriber to the free conventional channel.

Abstract
Methods and systems are provided for assigning channels in a spatial division multiple access communication network. The network includes a plurality of conventional channels some of which are configurable to be shared concurrently by plural subscribers. The method includes determining combinations of subscribers from the existing subscribers. Existing subscribers are reassigned to share channels thereby freeing resources for new subscribers.

28. A method for assigning channels in a spatial division multiple access communication network, the network including a plurality of conventional channels some of which are configurable to be shared concurrently by plural subscribers as spatial channels, the method comprising:
-
a determining if a new subscriber is to be added to the network; b. determining if a predetermined number of conventional channels are available, and if so, assigning the new subscriber to one of the available conventional channels; c. if the predetermined number of conventional channels are not available, determining one or more acceptable combinations of subscribers from the existing subscribers and not including the new subscriber to share a channel as spatial channels; d. reassigning the existing subscribers in each combination to share a channel creating one or more spatial channels thereby freeing at least one conventional channel; and e. assigning the new subscriber to the free conventional channel.

29. A method for assigning channels in a spatial division multiple access communication network, the network including a plurality of conventional channels some of which are configurable to be shared concurrently by plural subscribers as spatial channels the method comprising:
-
a. determining if a predetermined number of conventional channels are available; b. if the predetermined number of conventional channels are not available, determining one or more acceptable combinations of subscribers from the existing subscribers; c. reassigning the existing subscribers in each combination to share a channel creating one or more spatial channels thereby freeing at least one conventional channel for a future subscriber. - View Dependent Claims (30)

31. A method for assigning channels in a spatial division multiple access communication network, the network including a plurality of conventional channels some of which are configurable to be shared concurrently by plural subscribers as spatial channels, the method comprising:
-
a. determining a network loading threshold for conventional channels including determining a number of channels to be shared concurrently by plural subscribers as spatial channels and the number of subscribers to share each channel; b. determining one or more acceptable combinations of subscribers from the existing subscribers without violating the network loading threshold including reducing a number of subscribers assigned to at least one channel; and c. reassigning the existing subscribers as necessary to form the acceptable combinations creating one or more spatial channels and thereby freeing space on the one conventional channel for a future subscriber. - View Dependent Claims (32)
