A low-cost, flexible, high performance system and method comprises a means for
interfacing a code division wireless system to a fast packet-switched network for
transmission over a core network to a destination terminal user via a destination
access node and a destination access radio port. The method is for code division
switching at an originating terminal, the originating terminal being located within
a microport cell of a terrestrial wireless network at a given instant in time,
where said network interfaces with an access radio port, and comprises the steps
of spreading a transmission signal by a PN-code assigned to an intended receiving
port, inserting an identifier of a few bits for identifying a user, spreading a
payload data signal by an orthogonal code, spreading the orthogonal spread payload
data signal by the PN-code associating the user with payload data, modulating the
PN-code spread transmission signal and the twice-spread payload data signal, and
forwarding the modulated PN-code spread transmission signal and the modulated twice-spread
payload data signal to an access radio port. The code division switching system
at an originating terminal is described, the originating terminal being located
within a microport cell of a terrestrial wireless network at a given instant in
time, where said network interfaces with an access radio port, comprises a first
spreader for spreading a transmission signal by a PN-code assigned to an intended
receiving port, a second spreader for spreading a payload data signal by an orthogonal
code assigned to a receiving terminal user to which the payload data signal is
directed, the payload data signal being further spread by the first spreader, a
means for forwarding the PN-code spread transmission signal to an access radio
port and a means for forwarding the twice-spread transmission signal to an access
radio port.
