Abstract
Abstract A method and system are provided which allow a wireline network to dynamically control call redirection at a wireline Service Control Point (SCP) for mobile subscribers. A wireless location register routinely updates the wireline SCP with information indicative of the operational status of a mobile termination unit. The SCP is arranged to maintain the mobile unit status in a resident database. When a call is placed to a subscriber's home telephone number, an SSP will query the SCP for routing instructions, and in response, the SCP will merely access its maintained database to determine the status of the mobile unit. The SCP either sends a mobile identification number or equivalent address to the SSP if the mobile is available, or the home telephone number if the mobile is unavailable.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
198 words
In a communication system having a wireline network linked to a wireless network, a system for selectively directing call traffic originating from the wireline network to a mobile transceiver unit in the wireless network comprising: a wireless unit location register for maintaining a first database containing information indicative of mobile transceiver unit registration status and location; and a wireline service control point in communication with the wireless unit location register for maintaining a second database of data indicative of the availability status of the mobile transceiver unit, wherein the wireless unit location register is arranged to send data representative of the status of the mobile transceiver unit including a directory number to the wireline service control point for updating of the second database, wherein the service control point is arranged to access the second database directly when a request for call routing information is received from the wireline system, and providing information either for routing the call to the mobile transceiver unit based on the directory number maintained in the second database if the mobile unit is available to receive call traffic, or a designated wireline termination unit if the mobile unit is unavailable to receive call traffic.
Claim 2
Dependent Claim
198 words
In a communication system having a wireline network linked to a wireless network, a system for selectively directing call traffic originating from the wireline network to a mobile transceiver unit in the wireless network comprising: a wireless unit location register for maintaining a first database containing information indicative of mobile transceiver unit registration status and location; and a wireline service control point in communication with the wireless unit location register for maintaining a second database of data indicative of the availability status of the mobile transceiver unit, wherein the wireless unit location register is arranged to send data representative of the status of the mobile transceiver unit including a directory number to the wireline service control point for updating of the second database, wherein the service control point is arranged to access the second database directly when a request for call routing information is received from the wireline system, and providing information either for routing the call to the mobile transceiver unit based on the directory number maintained in the second database if the mobile unit is available to receive call traffic, or a designated wireline termination unit if the mobile unit is unavailable to receive call traffic.
Claim 3
Dependent Claim
230 words
In a communication system having a wireline network linked to a wireless network, a system for selectively directing call traffic originating from the wireline network to a mobile transceiver unit in the wireless network comprising: a wireless unit location register for maintaining a first database containing information indicative of mobile transceiver unit registration status and location; and a wireline service control point in communication with the wireless unit location register for maintaining a second database of data indicative of the availability status of the mobile transceiver unit, wherein the wireless unit location register is arranged to send data representative of the status of the mobile transceiver unit to the wireline service control point for updating of the second database, wherein the service control point is arranged to access the second database directly when a request for call routing information is received from the wireline system, and providing information either for routing the call to the mobile transceiver unit if the mobile unit is available to receive call traffic, or a designated wireline termination unit if the mobile unit is unavailable to receive call traffic, wherein the service control point is further arranged to determine whether an activity status timer associated with an available mobile unit has exceeded a predetermined value, and providing the information for routing the call to the mobile transceiver unit if the predetermined value is not exceeded.
Claim 4
Dependent Claim
230 words
In a communication system having a wireline network linked to a wireless network, a system for selectively directing call traffic originating from the wireline network to a mobile transceiver unit in the wireless network comprising: a wireless unit location register for maintaining a first database containing information indicative of mobile transceiver unit registration status and location; and a wireline service control point in communication with the wireless unit location register for maintaining a second database of data indicative of the availability status of the mobile transceiver unit, wherein the wireless unit location register is arranged to send data representative of the status of the mobile transceiver unit to the wireline service control point for updating of the second database, wherein the service control point is arranged to access the second database directly when a request for call routing information is received from the wireline system, and providing information either for routing the call to the mobile transceiver unit if the mobile unit is available to receive call traffic, or a designated wireline termination unit if the mobile unit is unavailable to receive call traffic, wherein the service control point is further arranged to determine whether an activity status timer associated with an available mobile unit has exceeded a predetermined value, and providing the information for routing the call to the mobile transceiver unit if the predetermined value is not exceeded.
Claim 5
Dependent Claim
34 words
The system of claim 2 wherein the service control point is further arranged to request the wireless network to initiate a forced registration process if the activity status timer has exceeded the predetermined value.
Claim 6
Dependent Claim
42 words
The system of claim 3 wherein the service control point waits for a mobile unit de-registration signal from the wireless network in response to the forced registration process before providing the information for routing the call to the designated wireline termination unit.
