摘要： A system for relaying CDMA packetized data from a cell site or sites to a destination speech processor. The CDMA packetized data, is received at the cell site and is sent in its packetized form along with a destination address to a packet switch. A packet handler at the packet switch receives the CDMA data packets and forwards them on a packet bus. If the destination speech processor assigned to that call is connected to the packet bus, it recognizes its own address and processes the data packet.

摘要： A system for delivering packetized data in a network comprising a plurality of packet switch communities, wherein each of the packet switch communities has a plurality of endpoints connected to a common packet switch and having a unique address, and wherein each of the endpoints has addresses unique to their respective packet switch community. The endpoints in this system add a two-part destination address to the packetized data to be sent, wherein the first field represents a packet switch community and the second represents a destination endpoint. Each packet switch community is responsive to the first field being different from its own address for delivering the packetized data to a switch. The switch is responsive to the first field for delivering the packetized data to a packet switch community identified by the first field. Finally, each endpoint in the destination packet switch community is responsive to the first and second address fields for accepting packetized data.

摘要： A system and method for delivering packetized data representing radio signals to and from cell sites, and to and from a destination point via a fast packet network. Each cell site includes an interface for packetizing the radio signals and transmitting the packetized data to its destination. The destination could be a delivery point at a switch connected to the telephone network, which then converts the packetized data into a form usable by the telephone network. Alternatively, the destination point could be another cell site, which then depacketizes the radio signal and retransmits the radio signal to another wireless communication device without connecting to the telephone network.

摘要： Soft handoff is provided in a mobile-to-mobile call in a cellular communication system, wherein a first mobile is moving from a first cell to a second cell, and the second mobile is in a third cell. The first mobile requests a handoff from the first cell to the second cell. In response, information regarding the call handoff is sent to the second and third cells. During handoff, the first and second cells receive radio transmission from the first mobile, and they both translate the transmissions into electronic data, packetize the data, and send the packetized data to the third cell. The third cell sends packetized data from the second mobile to both the first and second cells. Further, the second mobile may also move from the third cell to a fourth cell. The second mobile requests a handoff from the third cell to the fourth cell. Call data is sent to the fourth cell identifying the first and second cells. Call data is sent to the first and second cells identifying the fourth cell. The first and second cells thereafter transmit packetized data to the third and fourth cells, and the third and fourth cells send packetized data to the first and second cells.

摘要： A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024.times.1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination use that is in the same group (virtual network) as the source user. Each packet has an associated high or low priority indication. Requests for connections in the space division switch for a chained group of packets whose first packet has a high priority indication are given priority.

These controllers communicate via a separate control network with the data switching modules which request circuit connections.

In accordance with one embodiment of the invention, a packet switch is used for switching voice packet outputs of the data switching modules and a circuit switch, such as the space division switch, is used for switching data packet outputs. In accordance with another embodiment, voice packets are switched from the data switching modules through the space division switch to a small group of data switching modules, which further switch the voice packets through the circuit switch to a destination concentrator.
