Arrangement for and method of providing radio frequency access to a switching system
First Claim
1. A communication system comprisinga first radio port group server having an information capacity which does not exceed a predetermined information capacity for communicating over a facility to a first set of radio ports, each radio port arranged to communicate with one or more radio users over a radio link, the information capacity being shared among the first set of radio ports,a second radio port group server having a capability for communicating over said facility to one or more radio ports of the first set of radio ports assigned to said second group server and having a second predetermined information capacity, anda radio access controller for communicating with the first set of radio ports and responsive to a detected predetermined condition for changing an assignment of a first radio port from said first group server to said second group server such that said first radio port communicates with said second group server using an information capacity which does not exceed the second predetermined information capacity.

Abstract
A cellular communication system provides dynamic allocation of hardware resources and frequency spectrum. The cellular system includes a server which dynamically controls the assignment of radio ports to a first and second group; each group shares hardware resources. Radio ports assigned to a first group may be reassigned by the server to a second radio port group in response to a predetermined condition, such as when the number of active users in the first group approaches the maximum user capacity of the first group. The transceiver hardware of each radio port is pooled on a group basis at the server location. This increases the user capacity of any radio port of a group to equal the total user capacity available at that group, as well as making more efficient use of transceiver resources.

1. A communication system comprising
a first radio port group server having an information capacity which does not exceed a predetermined information capacity for communicating over a facility to a first set of radio ports, each radio port arranged to communicate with one or more radio users over a radio link, the information capacity being shared among the first set of radio ports, a second radio port group server having a capability for communicating over said facility to one or more radio ports of the first set of radio ports assigned to said second group server and having a second predetermined information capacity, and a radio access controller for communicating with the first set of radio ports and responsive to a detected predetermined condition for changing an assignment of a first radio port from said first group server to said second group server such that said first radio port communicates with said second group server using an information capacity which does not exceed the second predetermined information capacity.

23. A communication system comprising
a first radio port group server having an information capacity for communicating over a facility to a first set of radio ports, each radio port arranged to provide radio access to one or more members of a first set of radio users, identical information being radiated by all the radio ports to the first set of said radio users, and information radiated from each radio user in the first set being received by one or more of the radio ports of said first set, the information capacity being shared among the first set of radio users, a second radio port group server for communicating with a second set of radio ports over said facility, and a radio access controller for communicating with the first set of radio ports for dynamically changing an assignment of a first radio port from said first group server to said second group server in response to a predetermined condition.

58. A method of operating a communication system comprising the steps of
at a first radio port group server, communicating over a facility to a first set of radio ports, with an information capacity which is shared among the first set of radio ports; -
at each radio port, communicating with one or more radio users over a radio link having an information capacity which does not exceed the information capacity; at a second radio port group server, communicating over said facility to one or more radio users assigned thereto at up to a second information capacity; and at a controller, communicating with the first set of radio ports and, responsive to a detected predetermined condition, changing an assignment of a first radio port from said first group server to said second group server such that said first radio port communicates with said second group server using an information capacity which does not exceed the second information capacity.

59. A method of operating a communication system comprising the steps of
at a first radio port group server, communicating, at a predetermined information capacity, over a facility to a first set of radio ports, each radio port arranged to provide radio access to one or more members of a first set of radio users, identical information being radiated by all of the radio ports to the first set of radio users, and information radiated from each radio user in the first set being received by one or more of the radio ports of said first set, the predetermined information capacity being shared among the first set of radio users; -
at a second radio port group server, communicating with a second set of radio ports over said facility; and at a radio access controller, communicating with the first set of radio ports, monitoring and processing communication system load conditions and, in response to a predetermined load condition, dynamically changing an assignment of a first radio port from said first group server to said second group server.
