초록 ▼

A wireless-access communications system, such as a CDMA cellular radio-telephone system (FIG. 2), comprises a packet-switched communications network (202, 207, 201) that interconnects cells (base stations; 202) with each other and with the public telephone network (100). Traffic of individual calls is packetized, and packet-bearing frames (300 in FIG. 7) of a plurality of calls are then statistically multiplexed and frame-relayed through the network to yield the high capacity, efficiency, and speed of traffic transport and handoff required for a CDMA cellular system. At each call processing unit (264 in FIG. 5), individual calls are handled by individual service circuits (602 & 612) which perform speech-processing functions such as coding and decoding, tone insertion, and echo cancellation, and packet-to-circuit-switched-PCM traffic conversion. Processors (602) adapt call processing unit timing to compensate for asynchrony between cells and call processing units and variations in call path transmission delays. Cell-to-cell communications, fixed call path addressing, and packetized control message transfers ensure that the same service circuit handles a call through even multiple soft handoffs (FIGS. 27-29) and efficiently communicates simultaneously with all cells involved in the handoff without involvement of system control entities and negative effect on system call-handling capacity. Both coded (packet-switched) and uncoded (circuit-switched) radio-telephone traffic are accommodated side-by-side. Wherever possible, existing and proven technology and component units are used to achieve low cost and high reliability.

대표청구항 ▼

A switching system for conveying radio-telephone call traffic to and from cells over communications links in a radio-telephone communications system, the switching system being for connection to a plurality of communication channels of a telephone network that is connected to the radio-telephone communications system, each channel for carrying traffic of an individual call, and the switching system including: a packet transmission bus; a time-division-multiplexed (TDM) bus defining a plurality of time slots; a plurality of packet communications link interface means connected to the packet transmission bus and each for receiving from the packet transmission bus packets carrying outgoing voice call traffic destined for radio telephones served by a cell and transmitting the received packets on a packet communications link to the cell in statistically-multiplexed form, and for transmitting on the packet transmission bus packets received in statistically-multiplexed form on the link and each carrying incoming traffic of a voice call from a radio telephone; a plurality of call-handling means each connected to the packet transmission bus and to the TDM bus, each for handling a different call and responsive to receipt of outgoing voice call traffic of the handled call on the TDM bus in first time slots assigned to the handled call for packetizing the received outgoing call traffic and transmitting the packets at regular intervals on the packet transmission bus, and for receiving at regular intervals on the packet transmission bus packets carrying incoming voice call traffic of the handled call and for depacketizing and transmitting the incoming call traffic on the TDM bus in second time slots assigned to the handled call; and at least one channel interface means connected to the TDM bus, each responsive to receipt from a communication channel of a telephone network of outgoing call traffic of an individual call for transmitting the received outgoing call traffic on the TDM bus in first time slots that are assigned to the call, and responsive to receipt of incoming call traffic of an individual call on the TDM bus in second time slots that are assigned to the individual call for transmitting the received incoming call traffic on the communication channel of the telephone network that carries traffic of that call.
