Abstract

A method of radio communications and routing and connection in a mobile radio system consisting of the steps of providing nodes for transmitting and receiving signals wherein the nodes are positioned in a free form fashion within a defined area, and the routing of a communication is determined based on selecting the most desirable and normally the shortest path between the communication source and the destination drop.

Claims

1. In a cellular radio system comprising multiple remotes, nodes, channels and bands and wherein said system creates a communication path from a remote to a desired destination or drop, the method comprising,

a) creating radio routes to different drops based on routing information;

b) assigning channels along a multiple link route based on actual signal measurements without utilizing a central control; and

d) supporting multiple conversations going to different drops from said nodes.

2. A method as in claim 1 including the further step of

a) enabling multiple communications between nodes and concurrently enabling multiple communications to multiple remotes from said nodes.

3. A method as in claim 1 including the further step of handing off remotes to other nodes wherein said handing off utilizes new routes to the desired drop.

4. In a cellular radio telephone system with multiple remotes and multiple nodes, a method of handing off a remote comprising the following steps:

a) providing nodes that support multiple routes to a selected drop;

b) forming said routes from multiple links;

c) keeping a list at each node of active conversations;

d) checking said list at each node to determine if a new call is part of another call in process;

e) making the indicated connections based on said determination; and

f) utilizing different routes from said remote to said drop.

5. In a cellular radio duplex telephone system with multiple base sites, multiple bands, and multiple remotes a method of call route creation and connection comprising the following steps:

a) providing nodes that support multiple routes to selected drops;

b) selecting links that comprise preferred routes to each drop;

c) selecting said links based on band selection criteria and on actual signal strength;

d) combining said links to create routes to said drops;

e) assigning remotes to selected routes based on a desired telephone exchange;

f) assigning multiple remotes to routes which go through a given node with different drop destinations; and

g) handing off remotes to utilize other routes to a desired drop.

6. A method as in claim 5 including the step of operating on selected channels in said links.

7. A method as in claim 5 including the step of

a) choosing said links based on the highest minimum actual signal strength.

8. A method of handing off a remote user that comprises the following steps:

a) providing nodes that support multiple routes to selected drops;

b) selecting a route based on actual signal strength;

c) keeping a list of active conversations at each node;

d) checking said list at each node for each new call to determine if this is part of another call in process;

e) if this is a in process call, the making the indicated connections at each node; and

f) utilizing a different multiple link route for said remote to said drop.

9. A node in a radio communications system having a plurality of nodes functioning as repeater and as bases, remotes, routes, links and drops, said node comprising

a) radio transmitters and receivers for communications with multiple remotes in the direction of a drop;

b) radio transmitters and receivers for communication with multiple nodes;

c) radio transmitters and receivers for communication with nodes in the direction of a remote;

d) means for assigning a remote to a node;

e) means for selecting a route from a to a drop based on a selected telephone exchange identifier;

f) means for connecting remote to node transmitters and receivers to selected node to node receivers and transmitters when the node functions as a base; and

g) means for connecting node transmitters and receivers in the direction of a remote to selected node to node receivers and transmitters in the direction of the drop when the node functions as a repeater.

10. Apparatus as in claim 9 further comprising

a) mean for utilizing routing messages to participate in creating routes with multiple links.
