Abstract:
A method and apparatus is used for transmitting an outbound message (408) in a two-way messaging system having a plurality of cells employing frequency reuse. The controller (112) of the two-way messaging system divides ones of the plurality of cells into a plurality of rings based on radio frequency propagation and interference environment. The controller (112) then sends to a portable selective call transceiver (122) a notification of the outbound message (408). In response, the controller (112) receives information sufficient to determine an identity of one of the plurality of rings in which the portable selective call transceiver (122) has determined itself to be located, and transmits the outbound message (408) to the portable selective call transceiver (122), utilizing a frequency reuse plan in accordance with the identity.
Abstract:
A mobile device (106) comprising a processing system (206) including an interprocessor manager (308), and a plurality of processors (304-306) coupled to the interprocessor manager, wherein two or more of the plurality of processors are capable of processing a service application, and wherein the inter-processor manager is programmed to receive (402) a request to delegate the service application to at least one of the plurality of processors, select (406) an optimal one of the plurality of processors (304-306) to execute the service application according to a plurality of projected energy consumptions of the service application corresponding to each of the plurality of processors, and delegate (408) the service application to the optimal processor for execution.
Abstract:
A method (500) of activating an application in a client/server environment can include the steps of selectively highlighting (502) an application on a user interface on a client device (10) wirelessly linked to a server (25, 26, or 27) and launching and activating the application and connecting (508) to the server upon selecting an input (37) (such as such as a PTT button) on the client device. The step of selectively highlighting can include the optional steps of scrolling (504) through a phonebook menu of options and selectively highlighting a connectivity identifier (506) among a plurality of connectivity identifiers. The client device can optionally connect to the server via a network associated with the connectivity identifier selectively highlighted (510). The method can further include the step of receiving (512) a response from the server in a form emulating a push-to-talk response.
Abstract:
A method for context watermarking includes the steps of performing a Hash function "D" of the digital content (502). A Hash function "C" of the context information is also calculated (504). The Hash "D" is then appended to the context information (506) while the Hash "C" is appended to the digital content (508). The augmented content and context information are then packaged together (510) with the Hash values "D" and "C" helping to bind the content and context together. Instead of using Hash function other more sophisticated signatures can be used like those produced using Discrete Wavelet Transforms (DWT) or fractal-based transforms. An electronic device such as a radio communication device (700) capable of performing context watermarking is also described.
Abstract:
A system, method and computer readable medium for communicating data over a voice channel on a wireless device (300) is disclosed. The method on a wireless device (300) includes establishing an audio connection with a second device and providing an interface (326) for a user for sending data to the second device. The method further includes detecting the activation of the interface (326) by the user and sending a first data to the second device during the audio connection with the second device, wherein the quality of the audio connection is not affected by the sending. The method further includes receiving a second data from the second device, the second data being associated with the first data and preferably synchronizing the first data with the second data. Information, such as Vcard information, can be wirelessly exchanged between devices communicating data over a voice channel during an audio connection.
Abstract:
An IPC network (1900) allows for the dynamic composition of services. An IPC client (1902) can for example request a service, such as a new photo service, and teach the IPC network what service components comprise the service. The IPC server (1908) will wait until all of the required service components (1914, 1916) have registered with the IPC network (1900) prior to allowing the IPC client (1902) the go ahead to use the service. The dynamic composition of services allows clients/components operating in the IPC network (1900) to change service definitions without affecting the interprocessor communications between applications operating in the network (1900). Also, the IPC network (1900) learns dynamically the new service and is able to identify the availability of the service within the network (1900).
Abstract:
A mobile communication device (200) has a software architecture (302) that includes a closed operating environment (306). The closed operating environment is inaccessible to the user of the mobile communication device, and it includes software for implementing a reporting function designed to collect certain information from within the mobile communication device, and to transmit it to an entity outside the mobile communication device, such as a server (310).
Abstract:
A method and apparatus facilitates location tracking of a portable subscriber unit (122) in a radio communication system including a plurality of cells for providing radio communications with the portable subscriber unit (122). The plurality of cells are partitioned into subzones (402), a subzone (402) comprising at least one cell and utilizing at least one control channel. Each subzone (402) is assigned one of N subzone color codes (606). Adjacent subzones (402) have different subzone color codes (522), and same-valued subzone color codes (522) are reused in non-adjacent subzones (606). Control information is transmitted throughout each subzone (402) on the control channel (608) by a fixed portion (102) of the radio communication system. The control information includes the subzone color code (522) of the subzone (402). The portable subscriber unit (122) detects changes in the subzone color code (522), and thereafter, registers with the fixed portion (102) of the radio communication system in response.
Abstract:
A method and apparatus controls zone registrations in a radio communication system providing radio coverage to a portable subscriber unit (122, 1200) within a plurality of zones (402). A fixed portion (102) of the radio communication system cooperates with the portable subscriber unit (122, 1200) to adjust at least one registration variable in a memory of the portable subscriber unit (122, 1200) for moderating the zone registrations. The portable subscriber unit (122, 1200) then moderates the zone registrations to a limited number in accordance with the at least one registration variable.
Abstract:
A method and apparatus prioritize communications in a two-way communication system (102, 104) serving portable subscriber units (122) in a coverage area (500). A fixed portion (102) of the two-way communication system (102, 104) requests (904) location information (824, 224, 826) from a subset of the portable subscriber units (122) in response to having a need to communicate therewith, and then receives (906) the location information (824, 224, 826) from the subset of the portable subscriber units (122). The location information (824, 224, 826) includes mobility index values (826) determined by the subset of the portable subscriber units (122) for indicating mobility of each portable subscriber unit (122). The fixed portion (102) then prioritizes (908) the communications based upon the mobility index values (826).
