Method of communication to a detached terminal via a network
View Patent ↗A communication apparatus, which allows a user to communicate via a network, carries out a switch off step (SOA) in response to a switch off command. In the switch off step (SOA), the communication apparatus allows the user to select (SM 2 , SM 3 ) a detach message from a list of detach messages (DML). The communication apparatus conveys (SM 6 , SM 7 ) a detach message identification (MID) to the network and, subsequently, switches off (SM 8 ). The detach message identification (MID) represents the detach message that the user has selected. The network carries out a call handling step in which the network conveys the detach message to another communication apparatus from which a call emanates that is destined for the communication apparatus that is switched off.
1. A method, comprising:
responding, under control of at least one processing device of a first communication apparatus, to a switch-off command by:
prompting a user to select a detach message from a list of detach messages;
conveying a detach message identification to a network; and
after conveying the detach message identification to the network, switching off the first communication apparatus; and
subsequent to switching off the first communication apparatus, conveying, under control of the network and based on the detach message identification, a detach message to a second communication apparatus from which a call emanates that is destined for the first communication apparatus.
2. The method of claim 1 , the first communication apparatus conveying a detach request message to the network so as to signal the network that the first communication apparatus is about to be switched off, the detach message identification being included in the detach request message.
3. The method of claim 2 , the detach request message being in conformity with a communication standard, which provides that the detach request message comprises a spare portion, the communication apparatus including the detach message identification in the spare portion of the detach request message.
4. The method of claim 1 , further comprising allowing the user of the first communication apparatus to include user defined detach messages in the list of detach messages.
5. The method of claim 1 , the first communication apparatus determining, within a predefined time interval, whether the user has selected a detach message and, if the user has not selected a detach message within the predefined time interval, assigning a default value to the detach message identification that is conveyed to the network, the default value representing a default detach message.
6. A communication device, comprising:
a transceiver; and
at least one processing device coupled to the transceiver and configured to respond to a switch-off command by:
selecting a detach message from a list of detach messages;
generating control signals to cause a detach message identification corresponding to the selected detach message to be transmitted by the transceiver; and
after the detach message identification is transmitted by the transceiver, generating control signals to switch off the communication device.
7. A non-transitory computer-readable medium whose contents cause at least one processor of a communication apparatus to carry out a method in response to a switch-off command, the method comprising:
prompting a user to select a detach message from a list of detach messages;
conveying a detach message identification to a network based on the user selection; and
after the detach message identification is conveyed to the network, switching off the communication apparatus.
8. A network, comprising at least one processing device configured to implement:
a call handling module; and
a detach handling module configured to receive a detach message identification transmitted by a communication apparatus, the detach message identification representing a detach message that a user of the communication apparatus has selected in a switch off step, which ends by switching off the communication apparatus after the detach message identification is transmitted by the communication apparatus, wherein the call handling module is configured to convey the detach message to another communication apparatus from which a call emanates that is destined for the communication apparatus that is switched off.
9. A non-transitory computer-readable medium whose contents cause at least one processing device of a network to carry out:
a detach request handling step in which the network receives a detach message identification transmitted by a communication apparatus, the detach message identification representing a detach message that a user of the communication apparatus has selected in a switch off step, which ends by switching off the communication apparatus after the detach message identification is transmitted by the communication apparatus; and
a call handling step in which the network conveys the detach message to another communication apparatus from which a call emanates that is destined for the communication apparatus that is switched off.
10. The communication device of claim 6 wherein the at least one processing device is configured to select a detach message from a list of detach messages by generating signals to cause the communication device to prompt a user to select a detach message.
11. The communication device of claim 10 wherein the at least one processing device is configured to select a default message when a defined period of time elapses without a response to the prompt being received.
12. The communication device of claim 6 wherein the control signals to cause the detach message identification corresponding to the selected detach message to be transmitted cause a detach request message to be transmitted so as to signal a network that the communication device is about to be switched off, the detach message identification being included in the detach request message.
13. The communication device of claim 12 wherein the detach request message conforms with a communication standard, which provides that the detach request message comprises a spare portion and the control signals to cause the detach message identification to be transmitted cause the detach message identification to be included in the spare portion of the detach request message.
14. The non-transitory computer-readable medium of claim 7 wherein the method further comprises conveying a detach request message to the network so as to signal the network that the communication apparatus is about to be switched off, the detach message identification being included in the detach request message.
15. The non-transitory computer-readable medium of claim 14 wherein the detach request message complies with a communication standard, which provides that the detach request message comprises a spare portion, the method comprising including the detach message identification in the spare portion of the detach request message.
16. The non-transitory computer-readable medium of claim 7 wherein the method comprises determining whether the user has selected a detach message within a time interval and, if not, assigning a default value to the detach message identification that is conveyed to the network, the default value representing a default detach message.
17. The network of claim 8 wherein the detach handling module is configured to extract the detach message identification from a spare portion of a detach request message.
18. The non-transitory computer-readable medium of claim 9 wherein the detach request handling step comprises extracting the detach message identification from a spare portion of a detach request message.
