System for communicating digital cellular data between a cell site and a switching system or another cell site
First Claim
1. An improvement for the telephone network, said telephone network comprising a plurality of connection-based networks and a plurality of cellular communications networks, each of said cellular communications networks comprising a plurality of cell sites that communicate with a plurality of mobile units via radio signals, said cell sites converting data received in said radio signals into electronic data and convening electronic data into said radio signals, each of said connection-based networks having a plurality of delivery points which function to translate from said electronic data into a form used by said connection-based network and from said form used by said connection-based network into said electronic data, said improvement comprising:
- a single, high speed packet network, said high speed packet network having connections to each of said plurality of cell sites and each of said delivery points;
means at each of said cell sites for packetizing said electronic data for transmission by said high speed packet network, for transmitting and receiving said packetized communications on said high speed packet network, for depacketizing said electronic data, and for converting said depacketized electronic data into said radio signals; and
means at each of said delivery points for receiving and transmitting said packetized communications from said high speed packet network, for depacketizing said packetized communications into unpacketized communications and for translating said packetized communications into a format used by said connection-based network,wherein said high speed packet network delivers said unpacketized communications to any delivery point connected to said high speed packet network.

Abstract
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.

7. A method for transmitting cellular communications between a cell site and a public switched telephone network, said network including a delivery point for translating said cellular communications which are in a form used by cellular radio transmission into and out of a form used by said public switched telephone network, said cell site being in communication with one or more cellular devices via said radio transmission, said cell site and said delivery point being connected to a high speed packet network, said method comprising:
-
receiving radio signals from said cellular devices at said cell site; said cell site embedding a communications content of said radio signals in packets transmitted by said high speed packet network and transmitting said packets on said high speed packet network; said delivery point receiving ones of said packets, removing said embedded communications content from said packets, translating said cellular communications into a form used by said public switched telephone network, and delivering said translated cellular communications to said public switched telephone network. - View Dependent Claims (8, 9, 10)

11. A method for transmitting cellular radio signals between a first and a second cell site for a call from a first cellular device to a second cellular device without converting said call into a form used by a connection-based telephone network, said first and second cell sites having a connection to a high speed packet network, said method comprising:
-
receiving said radio signals from said first cellular device at said first cell site, said radio signals including a communication content; translating said communication content into electronic data; said first cell site embedding said electronic data into a packet and transmitting said packet to said second cell site on said high speed packet network; said second cell site receiving said packetized electronic data, removing said electronic data from said packet, translating said electronic data into said radio signals, and transmitting said radio signals to said second cellular device. - View Dependent Claims (12, 13)

14. A system for transmitting cellular radio signals between a first and a second cell site for a call from a first cellular device to a second cellular device without converting said call into a form used by a connection-based telephone network, said first and second cell sites connected to a high-speed packet network, said system comprising:
-
means for receiving radio signals from said first cellular device at said first cell site, said radio signals including a communications content; means at said first cell site for translating said communications content of said radio signals into electronic data, for embedding said electronic data into a packet and for transmitting said packet to said second cell site on said high speed packet network; and means at said second cell site for receiving said packetized electronic data, for removing said electronic data from said packet, for translating said electronic data into said communications content of said radio signals and for transmitting said communications content of said radio signals to said second cellular device.
