Disclosed are a wireless communication device and method for ringback control, and more particularly a device capable of receiving an incoming call, the device having a timing circuit configured to determine a delay for a predetermined period of time for ringtone generation at a calling party device.
In developing markets, demand for low cost or low tier wireless communication devices continues to grow. One aspect of satisfying the demand for devices is by making the devices more affordable. Low costs for manufacturing low tier wireless communication devices are maintained, in part, by limiting the number of components of the device. Use of a single output transducer for generating the sounds of the device may help maintain a lower cost in the manufacture of a low tier wireless communication device. The single transducer may generate sounds including a ringtone, alerts such as a low battery alert, as well as voice or audio communication output such as earpiece and speaker phone outputs.
In a device with a single output transducer, the transducer is positioned as an earpiece. Because a telephone may ring loudly, safety is a concern when the earpiece is adjacent to a user's ear. To avoid loud and potentially ear damaging sounds generated by the earpiece transducer, manufacturers can cause the transducer to incrementally increase sounds from soft to loud over a period of time. The ramp up of the transducer's sound can give the user an opportunity to pull the earpiece away from his/her ear before the transducer's sound becomes too loud.
The initial sound of a ramped up incoming call ringtone may be too low to be heard by the user when the earpiece is not adjacent to the user's ear. Accordingly, the call receiving party may not respond quickly to the incoming call ringtone due to the ramp up feature. A calling party, on the other hand, almost immediately receives an acknowledgment alert signal that the incoming call paging request signal has been received. Since the ringing may be generated by the wireless network infrastructure or the calling device itself upon receipt of the acknowledgment alert signal, it may seem to the calling party that the user of the call receiving device does not answer the incoming call. Accordingly, the calling party may terminate the call prematurely or hang up before the call receiving party answers the call. It would be beneficial if the acknowledgement alert signal sent to the calling party device were controlled so that ringing heard by the calling party at the calling party device can start later than the onset of the ramped up incoming call ringtone.
Disclosed is a wireless communication device capable of receiving a call from a calling party through a wireless infrastructure and of generating ringback control. The device can include a timing circuit configured to determine a delay for a predetermined period of time for ringtone generation at the calling party. The described ringback control may be processed by the call receiving device to control the timing of the ringtone generated at the calling party device. In one embodiment, the delay of the ringtone generation at the calling party is provided by delaying the transmission of the acknowledgment alerting signal by the wireless communication device until after the predetermined period of the delay. In another embodiment, the alerting signal includes a delay parameter so that the wireless infrastructure delays signaling a ringtone to the calling party. In another embodiment, the alerting signal includes a delay parameter so that the calling party device delays the activation of a ringtone. Accordingly, the acknowledgement alert signal sent to the calling party device can be delayed so that ringing heard by the calling party at the calling party device can start later than the onset of the ramped up incoming call ringtone. In this way, the calling party may be less inclined to prematurely terminate the call.
Also disclosed is a method for ringback control processed by a wireless communication device capable of receiving a call from a calling party through a wireless infrastructure and capable of determining a delay for a predetermined period of time for ringtone generation at the calling party and transmitting an alerting signal to the wireless infrastructure. Further disclosed is modulating the sound generated by the sound transducer of the wireless communication device to incrementally escalate sound and that the delay of a predetermined period of time can correspond to incremental escalation of sound from the sound transducer.

The remote server 106 is depicted as within a wireless infrastructure. The infrastructure of course may be any type of wireless network including an ad hoc or wireless personal area network, a WiFi or wireless local area network, and a cellular or wireless wide area network. Likewise, the server 106 may be of any suitable configuration. The server 106 may be implemented as a single server or as a plurality of servers in communication in any arrangement. The operations of the server 106 may be distributed among different servers or devices that may communicate in any manner. It is understood that the depiction in
Referring to wireless communication device 102, it may include a transceiver 108, a controller or processor 110, memory 112 and sound transducer 114 that may be the device's single sound transducer, and may be positioned at the earpiece 115. A single output transducer may be for generating the sounds of the device including a ringtone, alerts such a low battery alert, calendar, alarm clock and message alerts, as well as voice or audio communication output. It is understood that device 102 may include more than one transducer.
Modules 116, 118, 120 and 122 may include ringback control instruction modules that are hardware or software and may be stored in memory 112. The modules can carry out certain processes of the methods as described herein. The modules can be implemented in software, such as in the form of one or more sets of prestored instructions, and/or hardware, which can facilitate the operation of the mobile station or electronic device as discussed below. The modules may be installed at the factory or can be installed after distribution by, for example, a downloading operation. The modules can include a reception module 116, a determining module 118, a transmission module 120 and a delaying module 122. The operations in accordance with the modules will be discussed in more detail below.
The ramped up incoming call ringtone may take any form. Moreover, the same or similar ramped up transducer volume may be used for other sound generated by the transducer, such as a battery alert. Certain ringtones, for example a song, may linearly increase in volume. In one embodiment, the sound may increase according to a step function, for example every one or two seconds. The first increment may be an audible sound that is sufficient to be heard when the earpiece of the call receiving device is adjacent to the user's ear. However, it may not be sufficient to be heard when the earpiece is not adjacent to the user's ear. While sound escalates, the sound of the transducer may become easier and more audible to hear when not adjacent to the user's ear. For example, the escalation of sound may take place over any predetermined length of time, such as six or ten seconds. Accordingly, the delay of a predetermined period of time can be variable.
The delay of the alerting signal may be until the sound escalates to a predefined level. In one embodiment, the modulation of sound generated by a sound transducer of the wireless communication device may incrementally escalate sound from the sound transducer. Accordingly, the delay of a predetermined period of time can correspond to incremental escalation of sound from the sound transducer. In another embodiment, the predefined level is a sound pressure level (SPL) which is an acoustic measurement for the ratios of sound energy rated in decibels (SPL dBA, SPL dBC). Accordingly, the delay of the alerting signal may correspond to an SPL. In still another embodiment, the delay of the alerting signal is until the sound escalates to a predefined percentage of a total ring tone volume. It is understood that the sound may change in volume in any manner. Furthermore, the delay may be configured to correspond to the change in sound in any manner. Since the delay with audible alerts may be based on the SPL, the delay with non-audible alerts, such as vibrating alerts, may be accordingly low.
The delay may be automatically or manually configured. The delay may be configured by the manufacturer prior to shipment. Alternatively, the delay may be preset by the user by preference. Variable delays may be determined, for example, based on caller identification. Moreover, a delay may be determined on an ad hoc basis to the call receiving device in response to a prompt to the user. On the other hand, the delay may correspond to incremental escalation of sound from the sound transducer. In this way the delay of a predetermined period of time may be between about 0.1 seconds and about ten seconds. It is understood that any manner in which to determine the delay is within the scope of this discussion.
The incoming call receiving device 302 and the calling party device 304 generally transmit and receive signals via the wireless infrastructure 306. While this discussion refers to the calling party device 304 as a wireless communication device, as discussed above, it may also be any other type of device, including a wire line/land line device.
The calling party device 304 can initiate a call 308. In doing so the wireless infrastructure 306 may generate a paging signal request 310 to the incoming call receiving device 302. The transceiver (108, see
In one embodiment, a delaying module (122, see
In the described embodiment, the acknowledgement alert signal sent to the calling party device can be delayed so that ringing heard by the calling party at the calling party device can start later than the onset of the ramped up incoming call ringtone. It may therefore appear to the calling party that the call receiving device only just started to ring, even though the actual ringtone at the call receiving device 302 started a predetermined time earlier than heard by the calling party at the calling party device 304. The calling party of the calling party device therefore may be less inclined to terminate the call.
As mentioned,
The calling party device 404 can initiate a call 408. In doing so the wireless infrastructure 406 may generate a paging signal request 410 to the incoming call receiving device 402. The transceiver (108, see
In this embodiment, the alerting signal includes a delay parameter so that the wireless infrastructure delays signaling a ringtone to the calling party. Accordingly, the transmission of the alert signal 430 may be appended with an additional field indicating the delay for actuating a ringing at the calling party. The appended alert signal can be processed 432 by the wireless infrastructure 406. The ringing generated by the wireless infrastructure and heard by the calling party at the calling party device 404 can start later than the onset of the ramped up incoming call ringtone of the incoming call receiving device 402. Alternatively the ringing generated by the wireless infrastructure and heard by the calling party at the calling party device 404 can be generated with ramped-up amplitude according to the indicated delay.
As mentioned,
The calling party device 504 can initiate a call 508. In doing so the wireless infrastructure 506 may generate a paging signal request 510 to the incoming call receiving device 502. The transceiver (108, see
In this embodiment, the alerting signal includes a delay parameter so that the calling party device 504 delays signaling a ringtone to the calling party. Accordingly, the transmission of the alert signal 536 may be appended with an additional field indicating the delay for actuating a ringing by the calling party device 504. The appended alert signal can be processed 538 by the wireless infrastructure 506. The ringing therefore can be generated by the calling party device 540 and heard by the calling party at the calling party device 504 according to the delay parameter of the alert signal. The calling party device 504 may therefore process the ringback control parameter. Accordingly, the ringing heard by the calling party can start later than the onset of the ramped up incoming call ringtone of the incoming call receiving device 502. Alternatively the ringing heard by the calling party can be generated with ramped-up amplitude according to the delay ringback control parameter.

The described ringback control may be processed by a call receiving wireless communication device. Ringback control appended to the alert signal received by the wireless infrastructure and the calling party device may be processed as well. In a wireless communication device that incorporates ramp up transducer sound, including that of a device with one transducer, a wireless communication device having a timing circuit configured to determine a delay for a predetermined period of time for ringtone generation at the calling party, beneficially may avoid the calling party terminating a call. It is understood that any combination of the above-described embodiments is within the scope of this discussion. Furthermore, it is understood that certain wireless infrastructure adaptations may better facilitate the above-described technology.
