Abstract

An integrated wireless and wireline telecommunication switch. The switch includes peripheral modules having both wireless and wireline peripheral devices. The switch also includes wireless and wireline software load. An aspect table allows the wireless and wireline software load within the switch to be executed within a single call without creating direct dependencies on each other. The switch allows new and more efficient connections between wireless and wireline subscribers. In many cases wireless and wireline subscribers having direct access to the switch can connect without using any other switches in the network.

Claims

1. In an integrated wireless and wireline telecommunication switch, a method of establishing a call between wireless and wireline subscribers through the switch wherein both subscribers are served by the switch, the method comprising the steps of:

receiving an origination message from the wireless subscriber;

sending a set-up request to the wireline subscriber;

sending an alerting message to the wireless subscriber;

completing a connection to the wireline subscriber when the wireline subscriber answers; and

completing a telecommunication signal path between the wireless and wireline subscribers wherein the telecommunication signal path between the wireless and wireline subscribers is switched only by the integrated wireless and wireline telecommunication switch.

2. In an integrated wireless and wireline telecommunication switch, a method of establishing a call between wireline and wireless subscribers through the switch wherein both subscribers are served by the switch, the method comprising the steps of:

receiving and off-hook notification message from the wireline subscriber;

receiving called number digits from the wireline subscriber;

determining a location for the wireless subscriber through a request to a home location register;

paging the wireless subscriber;

sending an alerting message to the wireline subscriber;

completing a connection to the wireless subscriber when the wireless subscriber answers; and

completing a telecommunication signal path between the wireline and wireless subscribers wherein the telecommunication signal path between the wireline and wireless subscribers is switched only by the integrated wireless and wireline telecommunication switch.

3. In an integrated wireless and wireline telecommunication switch connected to an integrated public switched telephone network (PSTN) trunk, a method of establishing a call between wireless and wireline subscribers through the switch wherein both the wireless subscriber and the integrated PSTN trunk are served by the switch, the method comprising the steps of:

receiving an origination message from the wireless subscriber;

sending a first initial address message to a first wireline subscriber through the integrated PSTN trunk;

receiving a first alerting message through the integrated PSTN trunk;

sending a first audible alerting message to the wireless subscriber;

receiving a first answer message for the first wireline subscriber through the integrated PSTN trunk;

completing a first connection to the first wireline subscriber when the first wireline subscriber answers; and

completing a first telecommunication signal path between the wireless and wireline subscribers through the integrated wireless and wireline telecommunication switch and the integrated PSTN trunk.

4. The method of claim 3 further comprising the steps of:

receiving an off-hook notification message and called number digits from a second wireline subscriber, the second wireline subscriber connected to the switch via a direct signal path;

sending a second initial address message to a third wireline subscriber through the integrated PSTN trunk;

receiving a second alerting message through the integrated PSTN trunk;

sending a second audible alerting message to the second wireline subscriber;

completing a second connection to the third wireline subscriber through the integrated PSTN trunk when the third wireline subscriber answers; and

completing a second telecommunication signal path between the second wireline subscriber and the third wireline subscriber through the integrated wireless and wireline switch and the integrated PSTN trunk, thereby switching simultaneous wireless and wireline calls through the integrated PSTN trunk.

5. A computer program product for causing an integrated wireless and wireline telecommunication switch to establish calls between wireless and wireline subscribers, the computer program product having a medium with a computer program embodied thereon, the computer program comprising:

computer program code for receiving origination messages from wireless subscribers;

computer program code for sending set-up requests to wireline subscribers;

computer program code fore sending alerting messages to wireless and wireline subscribers;

computer program code for receiving off-hook notification messages and called digits from wireline subscribers;

computer program code for accessing location information in a home location register; and

computer program code for completing telecommunication signal paths between the wireless and wireline subscribers wherein the telecommunication signal paths between the wireless and wireline subscribers are switched only by the integrated wireless and wireline switch.

6. The computer program product of claim 5 wherein the computer program further comprises computer program code for completing telecommunication signal paths between wireless and wireline subscribers through the integrated wireless and wireline telecommunication switch and an integrated PSTN trunk.

7. Apparatus for establishing calls between wireless and wireline subscribers comprising:

means for receiving origination messages from wireless subscribers;

means for sending set-up requests to wireline subscribers;

means for sending alerting messages to wireless and wireline subscribers;

means for receiving off-hook notification messages and called digits from wireline subscribers;

means for accessing location information in a home location register for wireless subscribers; and

means for completing telecommunication signal paths between the wireless and wireline subscribers wherein the telecommunication signal paths between the wireless and wireline subscribers are switched only by the apparatus.

8. The apparatus of claim 7 further comprising means for completing telecommunication signal paths between wireless and wireline subscribers through the apparatus and an integrated PSTN trunk.
