A method and apparatus for managing institutional telephone activity utilizing a computer-based telephony management unit to connect institutional telephones with outside telephone lines. The unit provides institutional users with fully automated, direct dial and collect calling privileges for local, long distance, and international calls. The unit contains a database for storing the calling privileges and restrictions of institutional users, for recording calling transactions made by the users, and for managing user monetary accounts. The unit can record up to 400 hours of conversation in a digital format. The unit provides various administrative capabilities, including user account management, audit trails, transaction reports, centralized management and report capabilities, and detection of fraudulent calling.

A wireless headset for use with a separate communications device, such as a cellular telephone, includes automatic on / off capabilities to maximize battery life. By detecting a user's interaction, such as picking up the headset or placing it upon the user's body, the wireless headset automatically transitions from an inactive state to an active state. Techniques for automatic headset enabling include but are not limited to motion sensors, attitude or position sensors, proximity sensors, and contact sensors. These techniques may be used individually or in any combination. An internal timer allows the wireless headset to return to its inactive state a defined interval after cessation of movement or removal of the wireless headset. Including an optional sleep state further optimizes battery life. In the sleep state, only a portion of the wireless headset circuitry is enabled. Rather than transitioning from inactive to active, the headset transitions from inactive to sleep. In sleep, the headset periodically monitors for a signal from the separate communications device. Upon detection of such a signal, the wireless headset transitions to its active state, thereby providing full functionality to the user.

A processor (100) is provided that is a programmable fixed point digital signal processor (DSP) with variable instruction length, offering both high code density and easy programming. Architecture and instruction set are optimized for low power consumption and high efficiency execution of DSP algorithms, such as for wireless telephones, as well as pure control tasks. The processor includes an instruction buffer unit (106), a program flow control unit (108), an address / data flow unit (110), a data computation unit (112), and multiple interconnecting busses. Dual multiply-accumulate blocks improve processing performance. A memory interface unit (104) provides parallel access to data and instruction memories. The instruction buffer is operable to buffer single and compound instructions pending execution thereof. A decode mechanism is configured to decode instructions from the instruction buffer. The use of compound instructions enables effective use of the bandwidth available within the processor. A soft dual memory instruction can be compiled from separate first and second programmed memory instructions. Instructions can be conditionally executed or repeatedly executed. Bit field processing and various addressing modes, such as circular buffer addressing, further support execution of DSP algorithms. The processor includes a multistage execution pipeline with pipeline protection features. Various functional modules can be separately powered down to conserve power. The processor includes emulation and code debugging facilities with support for cache analysis.

A telecommunications system and method is disclosed for allowing network operators to download ringing tone pattern(s) associated with one or more musical scores to mobile stations (MSs) according to the music selection of mobile subscribers associated with the MSs. Once executed, the ringing tone pattern provides a musical ringing tone on the MS, instead of the normal ringing tone. In addition, ringing tone patterns can be used to enhance the "distinctive ringing" function within the MS. Thus, instead of using distinctive ringing patterns to represent different called party numbers, different music can be used.

A method for generating a ring tone for a given caller based on a prior conversation with that caller. A portion of a conversation with a given caller is recorded and stored in memory as a ring tone. When a subsequent call is received from the same caller, identified by caller ID, the ring tone is played, alerting the user to the incoming call as well as the context of their prior communication. In alternative embodiments of the invention, a prior textual or video conversation is used as the basis for a ring tone, and / or the ‘ring tone’ is delivered by other than audio means. The invention is capable of implementation in telecommunications systems such as cellular, local exchange, and VOIP, and in combination with other forms of internet-based telecommunication.

An audio processor (202) receives a non-priority audio signal (302) and a priority audio signal (304). The priority audio signal occupies a frequency band (408). The audio processor filters (320) the non-priority audio signal by suppressing frequency content in the same frequency region occupied by the priority signal, creating a filtered non-priority signal (412). The filtered non-priority signal and the priority signal are combined (328) and played over an audio transducer (110).

A mobile telephone (1), when being folded, is set in a lock state by an opening / closing detection and lock mechanism (50), and then a control circuit (30) stops supply of an electric power to a fingerprint authentication unit (60). In this state, upon detection of an incoming call from an external apparatus, the control circuit (30) restarts the supply of the electric power to the fingerprint authentication unit (60), and when a user is authenticated as a legitimate user by the fingerprint authentication unit (60), instructs the opening / closing detection and lock mechanism (50) to carry out an unlocking operation.

When a gateway detects that power from a primary power supply is disrupted or unavailable, reserve power, such as from batteries, is provided only to those components, ports, interfaces, and circuits associated with the gateway that are required for making a voice call or a lifeline call.

Sounds, alarms or other indications of conditions of potential interest that are produced by appliances and other household devices are detected by one or more sensors to trigger a notification signal that is sent to a remotely located user. The signals produced by the sensors are advantageously compared with a database of signals representing conditions of potential interest produced by known appliances and devices, producing the appropriate notification signal when a match is found. Notifications may be relayed to one or more selected users only when predetermined conditions are satisfied.

A portable phone is equipped with a position detector that detects the geographical position of the portable phone, and a telephone system may ring one or more land-based phones or portable phones according to the geographical position of the portable phone. One or more geographical regions are defined, with corresponding telephone parameters defined for each region. When a portable phone enters a defined region, exits a defined region, or changes between two defined regions, the function of one or more land-based phones or portable phones may change. The preferred embodiments thus allow changing the function of one or more other phones based on the self-detected geographical position of a portable phone. In this manner the convenience of using portable phones is greatly enhanced.

A method, computer-readable medium, and a computing device enable a user or other entity to select and / or customize alerts that can be triggered based on a notification event to thereby improve the ability of a mobile device to assist the user in distinguishing between multiple notification events. A user can create one or more separate and independent profiles for use with a mobile device. The user can preemptively control call interruptions and / or provide a type of alert used by the mobile device to inform the user of a particular notification event.
