Abstract
Abstract The Mobility Node (101) of the present invention maps signals, dialed digits, or other information from the mobile (140-142) to the appropriate protocols of the local exchange carrier's (LEC) Class 5 switch (120-123) and vice versa. If the signal does not have an LEC or base station equivalent, the Mobility Node (101) performs the appropriate processing. Multiple Mobility Nodes (101) are connected by a predetermined protocol link to enable inter-system communication.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
201 words
A wireless access system that enables a local exchange carrier to provide wireless access to wireline services by a mobile radiotelephone, the system comprising: a plurality of cells, each cell comprising a base station and antenna for communicating with the radiotelephone; a first set of local exchange carrier switches, each switch of said first set of local exchange carrier switches having a first set of input/output ports and a second set of input/output ports, each input/output port of said first set of input/output ports being assigned to a radiotelephone, each input/output port of said second set of input/output ports being coupled to a wireline subscriber unit, the first set of local exchange carrier switches coupled to other sets of local exchange carrier switches; and a Mobility Node connected to the input/output ports of said first set of input/output ports of each switch of said set of local exchange carrier switches, at least on cell of the plurality of cells, and a subscriber database, each Mobility Node additionally connected, through a predetermined protocol line, to other Mobility Nodes of the plurality of Mobility Nodes, each Mobility Node comprising a processor that converts predetermined signals from a first protocol to a second protocol.
Claim 2
Dependent Claim
201 words
A wireless access system that enables a local exchange carrier to provide wireless access to wireline services by a mobile radiotelephone, the system comprising: a plurality of cells, each cell comprising a base station and antenna for communicating with the radiotelephone; a first set of local exchange carrier switches, each switch of said first set of local exchange carrier switches having a first set of input/output ports and a second set of input/output ports, each input/output port of said first set of input/output ports being assigned to a radiotelephone, each input/output port of said second set of input/output ports being coupled to a wireline subscriber unit, the first set of local exchange carrier switches coupled to other sets of local exchange carrier switches; and a Mobility Node connected to the input/output ports of said first set of input/output ports of each switch of said set of local exchange carrier switches, at least on cell of the plurality of cells, and a subscriber database, each Mobility Node additionally connected, through a predetermined protocol line, to other Mobility Nodes of the plurality of Mobility Nodes, each Mobility Node comprising a processor that converts predetermined signals from a first protocol to a second protocol.
Claim 3
Dependent Claim
14 words
The system of claim 1 wherein the predetermined protocol line is an IS-41 line.
Claim 4
Dependent Claim
24 words
The system of claim 1 wherein the first protocol is a radio frequency protocol and the second protocol is a local exchange carrier protocol.
Claim 5
Dependent Claim
20 words
The system of claim 3 wherein the radio frequency protocol is IS-95 and the local exchange carrier protocol is TR303.
Claim 6
Dependent Claim
35 words
The system of claim 1 and further including each Mobility Node having a capability for handling hand-offs of the mobile radiotelephone from a first cell to a second cell, each of the plurality of cells.
Claim 7
Independent Claim
133 words
A method for a local exchange carrier to provide wireline services to a mobile radiotelephone through a local exchange carrier Class 5 office switch, the mobile radiotelephone communicating with base stations that are coupled to a port of the Class 5 office switch assigned to said mobile radiotelephone through a port of a Mobility Node assigned to said mobile radio telephone, the method comprising the steps of: monitoring, for a received signal, the port in the Mobility Node; if the received signal is from a Class 5 office switch, transforming the received signal from a local exchange carrier protocol signal to a radio frequency protocol signal; and if the received signal is from a base station, transforming the received signal from a radio frequency protocol signal to a local exchange carrier protocol signal.
Claim 8
Independent Claim
133 words
A method for a local exchange carrier to provide wireline services to a mobile radiotelephone through a local exchange carrier Class 5 office switch, the mobile radiotelephone communicating with base stations that are coupled to a port of the Class 5 office switch assigned to said mobile radiotelephone through a port of a Mobility Node assigned to said mobile radio telephone, the method comprising the steps of: monitoring, for a received signal, the port in the Mobility Node; if the received signal is from a Class 5 office switch, transforming the received signal from a local exchange carrier protocol signal to a radio frequency protocol signal; and if the received signal is from a base station, transforming the received signal from a radio frequency protocol signal to a local exchange carrier protocol signal.
Claim 9
Dependent Claim
33 words
The method of claim 6 and further including the step of the Mobility Node processing the received signal if an equivalent protocol does not exist to which the received signal can be mapped.
