Abstract
Abstract A telephone signaling system is operative outside of the traditional calling and data transmission paths to provide originating to termination signaling. Routing of the signaling is in response to a locator system which includes a data base of terminations and a system for keeping up to date information of current termination locations of the intended recipient. In one illustrative embodiment the termination equipment includes locator devices such as GPS locating devices. The information supplied by the GPS locating device is provided to a central data base which routes the signaling system to the intended recipient termination device. The central routing system then selects a voice and data transmission path that optimizes some preselected criteria of transmission. A typical criteria could be cost, or bandwidth or some combination of criteria to be optimized.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
130 words
A method of optimizing selected communication criteria in setting up a call between an originating telecommunication terminal and a terminating telecommunication terminal; CHARACTERIZED BY: selecting a signaling access network by; determining a location of the terminating telecommunication terminal and directing a signaling call set up request through intelligent signaling network paths to the destination determined by the terminating telecommunication terminal; establishing a communication dialog between the originating telecommunication terminal and terminating telecommunication terminal and each negotiating with each other and with a communication network criteria of a desirable bearer connection between the originating telecommunication terminal and terminating telecommunication terminal; upon coming to agreement on final selected desired criteria the signaling access network establishing a bearer communication path having the desired criteria between the originating telecommunication terminal and terminating telecommunication terminal.
Claim 2
Dependent Claim
37 words
A method of optimizing selected communication criteria as claimed in claim 1; including the further step of communicating locations of the originating telecommunication terminal and terminating telecommunication terminal to a data base in the signaling access network.
Claim 3
Dependent Claim
23 words
A method of optimizing selected communication criteria as claimed in claim 1; including using a signaling path physically independent of and bearer paths.
Claim 4
Dependent Claim
38 words
A method of optimizing selected communication criteria as claimed in claim 1; including the further step of continuing the signaling communication dialog between the originating telecommunication terminal and terminating telecommunication terminal subsequent to establishing a bearer communication path.
Claim 5
Dependent Claim
35 words
A method of optimizing selected communication criteria as claimed in claim 1; including the further step of communicating by wireless communication between the signaling access network and the originating telecommunication terminal and terminating telecommunication terminal.
Claim 6
Dependent Claim
241 words
A wireless common channel signaling network for locating a called telephone station and connecting a caller station with a called station with a bearer communication network set up according to criteria selected through the signaling network, comprising: the bearer communication network including a wired/wireless communication network (125, 127), a network of a plurality of signaling transport networks (107), a plurality of service switching points (123, 126), for interconnecting the network of a plurality of signaling transport networks to telephone switches (138), and a signaling service control point connected (109) to control a set up of a bearer network routing; CHARACTERIZED BY: the wireless common channel signaling network including: a signaling access node (105) for connecting a caller station and a called station to the network of a plurality of signaling transport networks; and a first and a second user signaling access unit (111, 112) connected to the caller station and the called station respectively; each signaling access unit including a stored program controller having a data base of subscriber based requirements, and a radio signaling system for communicating subscriber based requirements to and from the signaling access node and a bearer channel interface unit for communicating with the bearer network; the signaling access node communicating subscriber based requirements to the signaling service control point which sets up bearer network routing; and the bearer channel access unit communicating voice/data/video signals with the bearer network set up by the signaling service control point.
Claim 7
Dependent Claim
42 words
A wireless common channel signaling network as claimed in claim 6, with each user signaling access unit further including a GPS receiver (305) for generating a location signal which is communicated by the user signaling access unit to the signaling access node.
Claim 8
Dependent Claim
25 words
A wireless common channel signaling network as claimed in claim 6 wherein the bearer channel interface unit communicates with the bearer network by wireless communication.
Claim 9
Dependent Claim
25 words
A wireless common channel signaling network as claimed in claim 6 wherein the bearer channel interface unit communicates with the bearer network by wired communication.
