A system for providing communication in a distributed land mobile radio (LMR) system architecture. In some embodiments, the system includes a first controller associated with an LMR site. The first controller may be configured to control communication, via a communication channel, of a plurality of LMRs. In some embodiments, the system further includes a first repeater of a plurality of repeaters associated with the LMR site. The first repeater may include at least an active mode. The first repeater may be in the active mode to initiate a simulcast controller operation using the communication channel of the plurality of repeaters.

A device, system and method for controlling environmental devices at a smart building to assist a first responder is provided. A public-safety computing device determiners a context of a first responder at a smart building. The public-safety computing device is in communication with a smart-building control device. The context comprises one or more of: an objective to be achieved by the first responder in the smart building; and an object-of-interest in the smart building for which evidence is to be collected. The public-safety computing device communicates with the smart-building control device, to control environmental devices at the smart building to assist the first responder with respect to the context.

Methods, systems, and apparatus for smart speakerphone emergency monitoring are disclosed. A method includes detecting a sound at one or more of multiple locations of a property; determining that the sound indicates an emergency at the property; sending, to a monitoring station, an indication of the emergency; receiving, from the monitoring station, a two-way voice call; and broadcasting the two-way voice call to the multiple locations of the property. Detecting the sound at one or more of multiple locations of a property includes receiving audio data generated by one or more of a plurality of speakerphones, each speakerphone being located at one of the multiple locations of the property. Each speakerphone includes an audio microphone and an audio speaker, the speakerphone being configured to communicate with a speakerphone hub device using digital enhanced cordless telecommunications (DECT) signals.

A system and method for providing communication in a distributed LMR system architecture is provided herein, wherein the system includes a plurality of LMR subsystems interconnected by a data network. In some embodiments, a subsystem may include a distributed simulcast architecture comprising a plurality of LMR sites, each site having a subsystem controller and a plurality of repeaters. In one embodiment, one subsystem controller operates in an active mode and the remaining subsystem controllers operate in standby to provide redundancy. The repeaters include integrated voter comparator and simulcast controller functionality and circuitry. In some embodiments, the repeaters are operable in an active or standby mode, wherein repeaters in the active mode perform voter comparator and simulcast controller functionality. The distributed simulcast architecture provides simulcast controller and voter comparator redundancy, network failure redundancy, and site redundancy.

An improved emergency response system is provided. The system includes a patient or subscriber location database having a schedule of patient or subscriber activities. In one implementation, an emergency services server detects when the patient or subscriber is having a possible medical event as indicated by medical physiologic data transmitted from a wireless communication device proximate the patient. A third party such as a technologist and/or doctor diagnoses the patient and determines whether treatment is required. If treatment is required, a phone located remotely from the patient is used to call an emergency services first responder from a public safety access point in the patient's location. The remotely located phone has an automatic location identification database record that is updated based on the patient's current location as indicate by the patient location database. The address information in the patient location database includes street number, building number, floor and room number information, if applicable, to ensure that first responders are directed to the patient's specific location. Other implementations of the emergency response system are also described, including natural disasters, home security, and travel applications.

A call processing device includes: a conversion unit configured to convert a caller number of an emergency call sent from a terminal accommodation device via a wireless access line into a land line telephone number of a terminal accommodated by the terminal accommodation device; a connection unit configured to connect the emergency call with the converted caller number to an emergency service; and a notification unit configured to acquire an address corresponding to the land line telephone number and notify the emergency service of the address.
