Abstract

A mobile station communication network includes a high penetration network which schedules high transmission power level paging to reach a mobile station for which an acknowledgment signal is not received. A home location register stores mobile station high penetration network (HPN) subscriber feature information. The HPN analyzes mobile station class to determine an appropriate response when a mobile station fails to acknowledge a page request. The HPN further maintains a record of short message service (SMS) time out (timer) values and examines the ID of the center that generated the message to determine when the SMS center will time out. Just prior to the time out, the HPN will send a "user unavailable" signal to the originating SMS center to avoid unnecessary paging request retries by the SMS center.

Claims

1. A communication system for communicating with a mobile station, the communication station comprising:

a mobile switching center (MSC) for receiving a short message from a short message service (SMS) center and for receiving a call dialed to the mobile station, the MSC also for transmitting the short message and for routing the call to the mobile station; and

a high penetration node (HPN) within the MSC and coupled by transmitter/receiver to a satellite transceiver having high transmission power level transmission capability, the HPN controlling high transmission power level paging attempts by the satellite transceiver to a mobile station, the HPN comprising;

a first store for maintaining satellite transceiver orbit information and high beam level transmission capability information for a plurality of satellite transceivers for use by the HPN in scheduling high transmission power paging requests by a satellite transceiver following a failure by the mobile station to acknowledge a lower transmission power paging request; and

a second store for maintaining a bank of SMS center time out values, which HPN uses a time out value from the second store indicating when the SMS center will time out for determining when to transmit a signal prior to time out reflecting that the mobile station is unavailable.

2. A high penetration node (HPN) coupled to a mobile switching center, comprising:

a transmitter/receiver for communicating with at least one satellite transceiver having high transmission power level capability;

a satellite information store for storing satellite transceiver capability information and for storing satellite transceiver orbit information; and

means for scheduling high transmission power level transmissions from the at least one satellite transceiver, the means coupled to said transmitter/receiver for sending high transmission power level control commands to the at least one satellite transceiver through said transmitter/receiver according to information stored in the satellite information store following a failure by a mobile station to acknowledge a lower transmission power paging request.

3. The HPN of claim 2 further comprising a time out store for maintaining time out values of short message service (SMS) centers, which HPN uses the time out values to determine the timing of high transmission power level signal transmissions.

4. A high penetration node (HPN) coupled to a mobile switching center to receive a message generated by a short message service center, the high penetration node comprising:

a transmitter/receiver having high transmission power level capability;

means for scheduling high transmission power level transmissions from the transmitter/receiver following a failure by a mobile station to acknowledge a lower transmission power paging request;

a timer store for storing at least one short message service (SMS) center time out value for the short message service center; and

logic means coupled to said timer store, which logic means transmits a signal if a mobile station being paged does not acknowledge within the SMS center time out period, which signal reflects that a mobile station is unavailable, to the SMS center just prior to the expiration of the time out value since the transmission of the SMS message from the SMS center, the time out value being for the SMS center.

5. The HPN of claim 4 further comprising a satellite information store for storing satellite transceiver capability information and satellite orbit information wherein said HPN schedules high penetration beam paging requests according to satellite transceiver capability and orbit location.

6. A method, in a high penetration node, for paging a mobile station comprising the steps of:

receiving one of a message for delivery to a mobile station (MS) or a data packet for an incoming call to be connected to the MS;

receiving from a home location register (HLR) a signal reflecting high penetration subscriber features associated with the MS;

transmitting a first page request at a standard power level;

analyzing the high penetration subscriber features for the MS;

transmitting a second page request at a first high penetration beam power level if an acknowledge is not received after the first page and if the subscriber features indicate that a high penetration mode is enabled; and

wherein the mobile station is specified for those mobile stations whose subscriber features include high penetration mode transmissions.

7. The method of claim 6 further comprising the step of transmitting a third page request at a second high penetration beam power level if an acknowledge is not received after the first high penetration beam power level page and if the subscriber features indicate that a second high penetration beam mode is enabled.

8. The method of claim 6 further comprising the steps of:

receiving, from an SMS center time out store, a signal reflecting a time out value for the SMS center; and

transmitting a signal to the SMS center reflecting that the MS is unavailable, which signal is transmitted to the SMS center just prior to expiration of a time out value following a failure by the mobile station to acknowledge a paging request.

9. A method, in a communication system having high penetration mode transmission capabilities, of paging a mobile station, the method comprising the steps of:

receiving a signal to be communicated to a mobile station;

paging the mobile station at a low penetration power level;

paging the mobile station at a high penetration power level if the mobile station fails to respond to the low penetration power level page and is specified to receive high penetration power level paging service; and

wherein the mobile station is specified for those mobile stations whose subscriber features include high penetration mode transmissions.

10. The method of claim 9 wherein the signal to be communicated is a short message service center message.

11. The method of claim 9 wherein the mobile statioin is specified for those mobile stations whose geographic location is a specified location suited to receive high penetration mode transmissions.

12. The method of claim 9 wherein the mobile station is specified for those mobile stations whose International Mobile Subscriber Identity (IMSI) codes indicate that the mobile station is to receive high penetration mode transmissions.

13. The method of claim 9 wherein the signal to be communicated is an incoming call to be connected to the mobile station.

14. The method of claim 9 which further includes the step of transmitting a calling party phone number in second or subsequent paging attempts.
