Polling methods for use in a wireless communication system
View Patent ↗Polling methods for use in a communication system, such as a fixed wireless communication system, are described. The fixed wireless communication system includes at least one wireless base unit and a plurality of fixed-location wireless transceiver units, where each transceiver unit is, for example, located at a home residence and coupled to a personal computer (PC). In one particular polling method, a wireless transceiver unit detects a failure of a primary energy source, switches to a battery backup for power, and sends a message to the wireless base unit indicating such failure. The message initiates the wireless base unit to poll the wireless transceiver unit on a periodic basis for status information. During the failure, a data traffic channel established between the units is torn down to conserve power at the wireless transceiver unit. Once the primary energy source is restored, the data traffic channel is brought back up and the periodic polling is terminated. Similar methods are applied in connection with the detection of a communication failure over the data traffic channel.
1. A polling method for use in communicating information by a wireless transceiver unit to a wireless base unit, the wireless transceiver unit and the wireless base unit being configured to communicate over a wireless control channel and a wireless voice traffic channel, the polling method comprising:
receiving an information request message at the wireless transceiver unit over the wireless control channel;
in response to the information request message, sending call record information related to usage of the wireless voice traffic channel from the wireless transceiver unit to the wireless base unit over the wireless control channel; and
repeating the receiving and sending on a regular basis.
2. The polling method according to claim 1 , further comprising:
initiating the repeated receiving and sending in response to a detected problem.
3. The polling method according to claim 1 , further comprising:
detecting a problem at the wireless transceiver unit;
in response to detecting the problem, sending a problem detection message from the at the wireless transceiver unit to the wireless base unit; and
initiating the repeated receiving and sending in response to the problem detection message.
4. The polling method according to claim 1 , wherein the wireless transceiver unit and the wireless base unit are further configured to communicate over a wireless data traffic channel, the method further comprising:
detecting a communication failure on the wireless data traffic channel; and
initiating the repeated receiving and sending in response to detecting the communication failure.
5. The polling method according to claim 1 , further comprising:
detecting that a power failure has occurred; and
initiating the repeated receiving and sending in response to detecting that the power failure has occurred.
6. The polling method according to claim 1 , further comprising:
delaying a random period of time prior to sending the call record information.
7. The polling method according to claim 1 , wherein sending comprises sending the call record information over a shared wireless control channel, the polling method further comprising:
delaying a random period of time prior to sending the call record information over the shared wireless control channel.
8. The polling method according to claim 1 , wherein the information request message comprises data indicative of a requested call record information type and the call record information sent corresponds to the requested call record information type.
9. A polling method for use in communicating information from a wireless transceiver unit to a wireless base unit, the wireless transceiver unit and the wireless base unit being capable of communication over a wireless control channel and a wireless voice traffic channel, the polling method comprising:
sending an information request message from the wireless base unit to the wireless transceiver unit over a wireless communication channel, the information request message requesting call record information related to usage of the wireless voice traffic channel;
at the wireless base unit, receiving call record information from the wireless transceiver unit over the wireless control channel in response to the information request message; and
repeating the sending and receiving on a regular basis.
10. The polling method according to claim 9 , further comprising:
initiating the repeated sending and receiving in response to a detected problem.
11. The polling method according to claim 9 , further comprising:
receiving a problem detection message at the wireless base unit from the wireless transceiver unit; and
initiating the repeated receiving and sending in response to the problem detection message.
12. The polling method according to claim 9 , wherein the wireless transceiver unit and the wireless base unit are further configured to communicate over a wireless data traffic channel, the method further comprising:
detecting a communication failure on the wireless data traffic channel; and
initiating the repeated receiving and sending in response to detecting the communication failure.
13. The polling method according to claim 9 , wherein the wireless transceiver unit and the wireless base unit are further configured to communicate over a wireless data traffic channel, the method further comprising:
detecting a communication failure on the wireless data traffic channel;
tearing down the wireless data traffic channel but not the wireless voice traffic channel after detecting the communication failure; and
initiating the repeated receiving and sending in response to detecting the communication failure.
14. The polling method according to claim 9 , further comprising:
detecting that a power failure has occurred; and
initiating the repeated receiving and sending in response to detecting that the power failure has occurred.
15. The polling method according to claim 9 , wherein sending the information request message comprises broadcasting it for receipt by a plurality of wireless transceiver units, the polling method further comprising:
receiving the call record information from each one of the wireless transceiver units at random points in time.
16. The polling method according to claim 9 , wherein sending the information request message comprises broadcasting it for receipt by a plurality of wireless transceiver units, the polling method further comprising:
receiving call record information from each one of the wireless transceiver units at random points in time over a shared wireless control channel.
17. The polling method according to claim 9 , wherein the information request message comprises data indicative of a requested call record information type and the call record information sent corresponds to the requested information type.
