Abstract

A method for determining an open or available channel from a plurality of predetermined channels for communication between a portable unit and a mobile repeater unit operating within the same wireless communication system. After an available channel has been selected, communication between the portable unit and the mobile repeater unit is established on the selected channel, and the selected channel is identified as active to all other portable units and mobile repeater units operating on the system.

Claims

1. A method for a portable unit to communicate within a wireless communication system comprising at least one base station, at least one mobile repeater unit, and multiple portable units, comprising the steps of:

a. selecting a channel from a plurality of transmission channels;

b. transmitting a first query on said selected channel, said first query requesting responses from only mobile repeater units that are in active communication with another portable unit;

c. monitoring said selected channel for a predetermined period of time for a response to said first query;

d. if no response is received after said predetermined period of time elapses, selecting another of said plurality of channels;

e. if a response from a mobile repeater unit is received on said selected channel,

e.a. marking said selected channel as active;

e.b. storing quality parameters associated with said selected channel;

f. repeating steps a, b, c, d, and e for all remaining channels of said plurality of channels;

g. selecting the channel with the highest quality parameters;

h. sending a connection request to said channel with the highest quality parameters;

i. if a response to said connection request from a mobile repeater unit is received on said selected channel, determining if said one of said plurality of transmission channels is available for communication between said at least one portable unit and said at least one mobile repeater unit; and

j. if said one of said transmission channels is available, establishing communication between said portable unit and said responding mobile repeater unit on said one of said plurality of transmission channels and identifying said one of said plurality of transmission channels as active.

2. The method as set forth in claim 1 further comprising the step of:

k. if said channel selected in step g returns a negative response, repeating steps h and i for the next highest quality channel.

3. A method as set forth in claim 2 further comprising the steps of:

l. if no active mobile repeater unit responds to said first query;

l.a. selecting a channel from said plurality of transmission channels;

l.b. transmitting a second query on said selected channel, said second query requesting responses from only inactive mobile repeater units on said selected channel;

l.c. monitoring said selected channel for a predetermined period of time for a response;

l.d. if no response to said second query is received after said predetermined period of time elapses, selecting another channel from said list of channels; and

l.e. if a response from a mobile repeater unit to said second query is received on selected channel, sending a connection request to said mobile repeater unit.

4. A method as set forth in claim 3, wherein step l.e comprises the steps of:

l.e.a. marking said selected channel as containing an inactive mobile repeater unit;

l.e.b. storing quality parameters associated with said selected channel;

l.e.c. repeating steps e.a, e.b, f, and g for all remaining channels of said plurality of channels;

l.e.d. selecting the channel with the highest quality parameters; and

l.e.e. sending a connection request to said channel with the highest quality parameters.

5. A method as set forth in claim 4 wherein step l further comprises the steps of:

l.f. if said channel selected in step l.e.d returns an affirmative response, connecting to said channel; and

l.g. if said channel selected in step i l.e.d returns a negative response, repeating steps i l.d and l.e for the next highest quality channel.

6. A method of communication within a wireless communication system comprising at least one base station, at least one mobile repeater unit, and at least one portable unit, comprising the steps of:

a. selecting a channel from said plurality of transmission channels;

b. transmitting a first request on said selected channel, said first request requesting responses from only mobile repeater units “

that are in active communication with another portable unit”

;

c. monitoring said selected channel for a predetermined period of time for a response to said first request;

d. if no response to said first request is received after said predetermined period of time elapses, selecting another channel from said list of channels; and

e. if a response from a mobile repeater unit to said first request is received on said selected channel, marking said selected channel as active;

f. if a response to said first request is received from a mobile repeater unit on said selected channel, storing quality parameters associated with said selected channel;

g. repeating steps a, b, c, d, e, and f for all remaining channels on said predetermined list of channels;

h. selecting the channel with the highest quality parameters; and

i. sending a connection request to said channel with the highest quality parameters;

j. if said channel selected in step h returns an affirmative response, connecting to said channel;

k. if said channel selected in step h returns a negative response,

k.a. selecting a channel from said plurality of transmission channels;

k.b. transmitting a second request on said selected channel, said second request seeking response from only mobile repeater units “

that are not in active communication with another portable unit”

;

k.c. monitoring said selected channel for a predetermined period of time for a response to said second request;

k.d. if no response to said second request is received after said predetermined period of time elapses, selecting another channel from said list of channels; and

k.e. if a response to said second request is received from a mobile repeater unit on said selected channel, marking said selected channel as containing an inactive mobile repeater unit;

k.f. if a response from a mobile repeater unit to said second request is received on said selected channel, storing quality parameters associated with said selected channel;

k.g. repeating steps k.a, k.b, k.c, k.d, k.e, and k.f, for all remaining channels;

k.h. selecting the channel with the highest quality parameters; and

k.i. sending a connection request to said channel with the highest quality parameters;

7. The method as set forth in claim 6 further comprising the steps of:

l. if said channel selected in step k.h returns an affirmative response, connecting to said channel; and

m. if said channel selected in step k.h returns a negative response, repeating steps k.h and k.i for the next highest quality channel.
