Abstract:
Communications may be established based on geographic location when a communication resource controller (101) transmits a communication message (119), which includes a message ID (120) a communication payload (121), and a set of geographic coordinates to a plurality of communication units (102, 103). Each communication units (102, 103) upon receiving the communication message (119), compares its identification code (122) with the message ID (120). If a match occurs, the communication unit (102, 103) then determines its geographic location. Having obtained the geographic location, the unit determines whether its present location is within the area defined by the set of geographic coordinates and, if so, adjust its receiver to receive the communication payload (121).
Abstract:
A personal communications device (100) includes a wireless transceiver (206, 207, 208) to allow a two-way exchange of user information, and to allow down loading of remote control signalling information. The latter can be transmitted via an appropriate transmitter (210 or 211) to facilitate remote control of a remote controlled device.
Abstract:
A method is employed by a central controller of a radio communications system, which method provides for sustaining a predetermined level of communication service. The system includes a plurality of voice channels which are allocated among a plurality of subscribers (108-112) using a first control channel (102). In a preferred embodiment, at least one of the voice channels (104, 106) is also control-capable. The method includes evaluating (504) a current loading condition, and comparing (504) this loading condition with an upper loading threshold. Where appropriate, the controller assigns (506) one of the control-capable voice channels as a temporary control channel.
Abstract:
A system and method for providing single channel remote site trunking is described. The present invention allows for radios operating in single channel non-dedicated control channel sites (104) to communicate with radios in dedicated control channel sites (102) which are part of the system. Further, the present invention will allow for non-trunked radios to utilize the benefits of trunking when operating in the single channel remote site. By mapping the ID's of the radios in the system, the system can keep track of all radios in the system whether in a remote single site (104) or in one of the dedicated control channel sites (102) and thereby link radios in one site to automatically communicate with the radios in the other site.
Abstract:
Un procédé (215) autorise la transformation d'un canal de commande en un canal de communication (vocal/données), ce qui permet de maintenir un niveau prédéterminé de service dans un système de radiocommunications. Il recourt à un contrôleur central (101) qui attribue un nombre limité de canaux de communications à plusieurs postes d'abonnés (108-112). Après avoir reçu (203) une demande de canal de communication émanant de l'un de ces postes d'abonnés (108-112), le contrôleur (101), s'il détermine (205) que tous les canaux de communication sont occupés, transforme (215) alors temporairement le canal de commande en canal de communication.
Abstract:
Un dispositif de télécommunications personnel (100) comprend un émetteur récepteur sans fil (206, 207, 208) permettant l'échange bidirectionnel d'informations d'utilisateur et permettant le téléchargement de signaux de commande à distance. Ces signaux peuvent être transmis par l'intermédiaire d'un émetteur approprié (210, 211) pour faciliter la commande à distance d'un tel dispositif.
Abstract:
Described are methods and devices for identifying a group that include various methods to determine a group. Also described are devices and methods for attempting communication with a missing member (114) of the group include different manners in which to determine information related to an entry of a group. The described devices and methods may be particularly beneficial at the particular time the certain group members (102, 106, 108) plan to be or are in communication (104) with one another. In this way, in the event that two or more entries (102, 106, 108) of a group planned to be in communication or are in communication (104) in-real time, in accordance with the disclosed devices and methods, the parties (102, 106, 108) may be able to bring one or more other entries (114) of the group into the communication (104) as needed or desired.
Abstract:
A wireless transmitter (400) having a quantity of data to transmit (101) can automatically determine (102) whether that data can be transmitted using a first transmission state in a manner that complies with regulatory requirements as will apply to such a transmission state. When true, these teachings can provide for automatically transmitting (108) that data using that first transmission state. When not true, however, these teachings will then provide for automatically determining (103) whether this data can be transmitted using a second transmission state in a manner that is appropriately compliant with the salient regulatory requirements. By one approach, this second transmission state is at least partially different from the first transmission state but offers a substantially comparable quality of service. When true, these teachings then provide for transmission (105) of that data using this second transmission state.
Abstract:
A method (215) of converting a current control channel for use as a communication (voice/data) channel, in order to maintain a predetermined level of service in a radio communications system, employs a central controller (101) to allocate a limited number of communication channels among a plurality of subscriber units (108-112). After receiving (203) a request for a communication channel from one of a plurality of subscriber units (108-112), the controller (101) determines (205) whether all of the communication channels are busy. The controller then temporarily converts (215) the current control channel to a communication channel.
Abstract:
While participating in a group call on a first wireless communication resource (114), senior members (104-107) of a communication group (108) can initiate a semi-private call. A central controller (110) allocates a second wireless communication resource (115) for the semi-private call. Furthermore, executive members (106-107) can initiate an executive call to be established on a third wireless communication resource (116). Executive members can participate in the executive call, the semi-private call, and the group call, whereas senior members can participate in the semi-private call and the group call. Junior members (101-103), normally allowed to participate only in the group call, can be selected by senior members to temporarily participate in the group call and the semi-private call.
