A wireless telecommunications network includes a base station controller which, in turn, is comprised of a call control resource manager and a multiple technology vocoder having first and second interfaces, first and second selection managers, a vocoder controller and first, second, third, fourth and fifth resources, each embodied as a software module, for performing D/A and A/D conversions on messages configured in accordance with EVRC, EFRC, RLP, VSELP and QCELP protocols, respectively. When transferring messages between a mobile terminal and an MSC via the base station controller, the mobile terminal first informs the call control resource manager of the protocol to which the message conforms. In turn, the call control resource manager advises of the vocoder controller of the protocol type for the incoming message. The vocoder controller configures the interfaces to accept messages formatted in the protocol and instructs the selection managers to provide a path, for the received message, to the appropriate resource for conversion. The converted message is then returned to the call control resource manager and transmitted on to its final destination.

The apparatus of claim 7 wherein the system is a fixed wireless loop system. 9. The apparatus of claim 7 wherein the code division multiple access technique is time-slotted code division multiple access. 10. The apparatus of claim 7 wherein the given antenna beam comprises an electronically-steered beam at a particular point in time, and has a width sufficient to provide simultaneous coverage for at least n of the plurality of subscriber units at that time, where n is greater than or equal to two. 11. The apparatus of claim 7 wherein the base station is further operative to assign a first subset of a set of time slots to the uplink and a second subset of the set of time slots to the downlink. 12. The apparatus of claim 11 wherein the base station is further operative to vary the assignment of time slots to uplink and downlink in accordance with uplink and downlink traffic demands. 13. An apparatus for communicating information in a wireless communication system, the apparatus comprising: a first subscriber unit operative to communicate with a base station in a cell of the system over at least one of an uplink and a downlink, wherein communications on the uplink are separated from communications on the downlink using time division duplexing, and communications between the base station and at least one other subscriber unit in the cell are separated from communications between the base station and the first subscriber unit using a code division multiple access technique; wherein each of the subscriber units within a given antenna beam associated with a given sector of the base station is assigned a distinct beam-specific spreading code, the beam-specific spreading code being used in conjunction with a sector-specific spreading code to separate the communications between the base station and the subscriber units within the given antenna beam in accordance with the code division multiple access technique. 14. The apparatus of claim 13 wherein the system is a fixed wireless loop system. 15. The apparatus of claim 13 wherein the code division multiple access technique is time-slotted code division multiple access. 16. The apparatus of claim 13 wherein the given antenna beam comprises an electronically-steered beam at a particular point in time, and has a width sufficient to provide simultaneous coverage for at least n subscriber units at that time, where n is greater than or equal to two. 17. The apparatus of claim 13 wherein the time division duplexing assigns a first subset of a set of time slots to the uplink and a second subset of the set of time slots to the downlink. 18. The apparatus of claim 17 wherein the assignment of codes to uplink and downlink is repeated for each of a plurality of time slots, such that the number of codes in the first and second subsets varies in accordance with uplink and downlink traffic demands. 370/210; US-4425639, 19840100, Acampora et al., 370/050; US-4660196, 19870400, Gray et al., 370/109; US-4881222, 19891100, Goeckler et al., 370/484; US-4901310, 19900200, Ichiyoshi, 370/075; US-4931802, 19900600, Assal et al., 342/356; US-5148452, 19920900, Kennedy et al., 375/096; US-5274627, 19931200, De Santis, 370/307; US-5278837, 19940100, Kelley, 370/343; US-5283780, 19940200, Schuchman et al., 370/050; US-5293382, 19940300, Carson et al., 370/210; US-5299192, 19940300, Guo et al., 370/210; US-5303393, 19940400, Noreen et al., 455/003.2; US-5347548, 19940900, Messerges et al., 375/116; US-5416774, 19950500, Shigematsu et al., 370/069.1; US-5455823, 19951000, Noreen et al., 370/050; US-5473601, 19951200, Rosen et al., 370/050; US-5521943, 19960500, Dambacher, 375/295; US-5550812, 19960800, Philips, 370/019; US-5555547, 19960900, Lemaitre et al., 375/262; US-5663986, 19970900, Striffler, 375/260; US-5668842, 19970900, Sorace et al., 375/308; US-5689245, 19971100, Noreen et al., 340/825.39; US-5796726, 19980800, Hassan et al., 370/322; US-5867490, 19990200, Campanella, 370/326; US-6108317, 20000800, Jones et al., 370/320; US-6108319, 20000800, Campanella, 370/324; US-6333922, 20011200, Campanella, 370/319 performed.
