A configurable apparatus includes a housing, a cradle, and a handset. In a first configuration, a first bracket is releasably attached to the cradle and to the housing such that the cradle is disposed next to a first side of the housing. In a second configuration, a second bracket is releasably attached to the cradle and to the housing such that the cradle is disposed next to a second side of the housing. The first and second brackets can include L-shaped brackets, which can be mirror images of each other. The communication system may be used in multi-story buildings or similar structures to facilitate communications among multiple stations (e.g., emergency response stations) within the structures.

Disclosed are a walkie-talkie and a walkie-talkie information transmission method. The walkie-talkie includes: an interconnection communication module, configured to establish short-range communication with an interconnection terminal; a radio frequency module, configured to establish radio frequency communication with another walkie-talkie; an internal communication interface; and a processor connected to the interconnection communication module and the radio frequency module through the internal communication interface; the processor is configured to: receive, through the interconnection communication module, a first signal sent by the interconnection terminal towards the other walkie-talkie, process the first signal to obtain a second signal, and send the second signal to the other walkie-talkie through the radio frequency module; or receive, through the radio frequency module, a third signal sent by the other walkie-talkie towards the interconnection terminal, process the third signal to obtain a fourth signal, and send the fourth signal to the interconnection terminal through the interconnection communication module.

A method of managing communications between communication devices within a digital intercom system includes providing input and output tables for each communication device. The tables for each device are made up of cells formed from linear arrays corresponding to communication channels and the other devices. When two devices communicate on a given channel, a cell in the appropriate input and output table is identified based on the channel and the devices communicating. The cells provide volume control information which can be relied upon to determine if or to what degree audio signals should be transferred between the devices.

Enhancements of and to cell phone operations are based in whole or in part on determining the location of the cell phone. Systems and methods select and determine locations or areas of importance or relevance, and based on that information and other programmed factors affect or alter the operations of the cell phone. While the systems and methods are illustrated by use of cell phone embodiments and applications, they are equally applicable to virtually any portable or mobile communication device, including for example, wireless laptop computers and PDAs.

In one embodiment, a headset receives, via a first service type of a wireless connection between a first telephony device and the headset, call-session identifier data of an active call maintained by the first telephony device. Media associated with the active call is communicated via a second service type of the wireless connection between the headset and the first telephony device. The headset sends to a second telephony device via a first service type of a wireless connection between the second telephony device and the headset, the call-session identifier data to enable the active call to be transferred from the first telephony device to the second telephony device based on the call-session identifier data. The headset receives from the second telephony device via a second service type of the wireless connection between the second telephony device and the headset, media for the active call.

In general, the invention relates to a system and method of operating a shopping system to facilitate payment using a mobile device. A network is configured to include a server programmed with a personal characteristic database, a database searching algorithm, and to be coupled to a wireless communication system that is capable of communicating with the user's personal data device. The user logs on through the wireless communication system to the secure network using her personal data device, and communicates to and stores in the database personal data defining her characteristics. Either the secure network automatically identifies the first users precise geographic location, or the user himself otherwise indicates and stores in the database of the network an identifying address that indicates his current specific geographic location. Personal data defining the user's characteristics are then sent to a business location at the user's location to facilitate a payment transaction.

A method for identifying a Bluetooth headset voice source includes: S1: establishing a connection between a device itself, that is, a first Bluetooth headset, and a smart terminal and a connection between the first Bluetooth headset and a second Bluetooth headset separately; and S2: when the first or second Bluetooth headset sends a voice, establishing a data control channel by using Generic Attribute Profile and Attribute Protocol, sending a corresponding identifier to the smart terminal according to different voice sources, and then sending the voice to the smart terminal. A device for identifying a Bluetooth headset voice source includes a baseband circuit (1), a memory (2), and a main controller (3). The program in the memory (2) is used for performing the method for identifying a Bluetooth headset voice source. The method and device can solve the problem about identifying voice sources of two Bluetooth headsets.
