| 455421000 | Out-of-range indication | 10 |
| 20100035598 | WIRELESS COMMUNICATION OUT OF RANGE INDICATION - With respect to a wireless network, an out of range warning provides an estimate of an amount of time remaining until a wireless device is out of range of the wireless network. In this way, the user is presented with an opportunity to take corrective measures, if desired. | 02-11-2010 |
| 20080268830 | Proximity detection of coverage area boundary and display of mobile station location relative thereto - A method is provided for producing a user perceivable warning output by a mobile station ( | 10-30-2008 |
| 20090247147 | Predictive Mobile Phone Service Disruption Service - Illustrative embodiments provide a computer implemented method, a data processing system and a computer program product for a predictive mobile phone service disruption service. In one illustrative embodiment, the computer implemented method comprises monitoring a cellular call of a caller, calculating a location and vector of the caller, and determining whether the caller is approaching a drop zone. The computer implemented method responsive to determining the caller is approaching a drop zone, estimates a duration of a loss of service, and responsive to determining the caller is approaching a drop zone, selectively notifying the caller. | 10-01-2009 |
| 20090111455 | METHOD OF SETTING THE DISPATCH AREA BASED ON THE CLUSTER SYSTEM OF CDMA TECHNOLOGY - The present invention relates to a method for allocating dispatch service areas for trunking system based on code division multiple access technology, comprising: dividing the service area of a trunking system into a plurality of dispatch location areas geographically not overlapping each other; assigning one or a plurality of dispatch location areas as dispatch service area for each fleet on the push-to-talk home register of above trunking system; assigning dispatch service areas for groups of above fleet, wherein the dispatch service areas of the groups should be full set or subset of the fleet's dispatch service area; synchronizing information of dispatch service areas from network side to mobile station by updating user information; system parameter message of base station has the information of dispatch location area that this cell belong to, to inform the mobile station whether it is out of a dispatch service area, and the push-to-talk home register will control the trunking conversation of said mobile station based on whether the mobile station locates in the dispatch service area. The present invention is capable of meeting the requirements for performing the service functions of the trunking system, such as out-the-dispatch-area indication and service area selection. | 04-30-2009 |
| 20090312002 | METHOD AND SYSTEM FOR SIGNAL FIELD STRENGTH PREDICTION IN COMMUNICATION SYSTEMS - A method and system for communication involving a mobile station and one or more radio base stations providing a signal field in an area, is provided. One implementation includes determining signal field variation at a mobile station in said area due to motion of the mobile station relative to the base stations; and predicting the time remaining to an eventual drop of the signal field by estimating the time remaining to an eventual drop of the signal field based on a rate of variation of the signal field. | 12-17-2009 |
| 20110086632 | OBJECT RANGE DETECTOR AND LOCK DOWN DEVICE - A range detector system includes an safety system, a first electronic object, and a second electronic object, wherein the first and second electronic objects are wirelessly communicably connected in a manner equipped such that when the first object and the second object are moved from a first predetermined distance range from each other to a second predetermined distance range from each other, the safety system is operably deployed on at least one the first and the second objects is activated. | 04-14-2011 |
| 20090286526 | RADIO QUALITY DEGRADATION PREDICTION SYSTEM, WIRELESS TERMINAL AND MONITORING SERVER THEREFOR, RADIO QUALITY DEGRADATION PREDICTION METHOD AND PROGRAM - A radio quality degradation prediction system includes a wireless terminal and a monitoring server. The wireless terminal includes a positioning unit that determines a position of the wireless terminal and notifies the monitoring server of movement history of the wireless terminal via a wireless network, and a user notification unit that gives a warning to a user upon receiving a radio quality degradation alert at the wireless terminal. The monitoring server includes a future position prediction unit that predicts a future position of the wireless terminal based on the movement history of the wireless terminal, a radio propagation prediction unit that estimates radio quality in a service coverage area by using a radiowave propagation simulator, and a quality degradation prediction unit that predicts degradation of radio quality at the future position of the wireless terminal and transmits a radio quality degradation alert to the wireless terminal. | 11-19-2009 |
| 20120157081 | LEADERSHIP SUPPORT SYSTEM DETERMINING A DANGER OF ISOLATION OF A GROUP MEMBER EVEN UNDER TEMPORARILY WORSENED COMMUNICATION CONDITIONS - A leadership support system includes a leader terminal and plural member terminals. The member terminals, according to either the relay of communication information not addressed thereto or the reception of communication information addressed thereto, send back a response to the appropriate communication information. The leader terminal determines, based on the times of relaying the communication information, whether or not the member terminal that transmitted the communication information is in danger of isolation. When the leader terminal determines the member terminal in danger of isolation, it outputs a warning signal indicative of a ranger of isolation to that member terminal. | 06-21-2012 |
| 20100173623 | Mobile Terminal - A mobile terminal includes a first communication module, a second communication module, a state management module configured to make an out-of-range notification when a communication state of the first communication module moves out of a communication range, a notification module configured to send a user notification as a notification indicating that the first communication module is disconnected to a user when the out-of-range notification is received, a determination module configured to determine whether or not a given process for the user notification is completed, a setting module configured to perform setting indicating that the process for the user notification is completed to the state management module when the determination module determines that the process is completed, and a communication prohibition module for prohibiting the data communication by the second communication module until the setting indicating that the process is completed is performed after the communication state of the first communication module moves out of the communication range. | 07-08-2010 |
| 20080233944 | Method, Apparatus, Computer Program Product and System for Providing Dynamic Assignment of Session Capabilities - An apparatus for providing dynamic assignment of session capabilities such as buddy list capabilities includes a processing element. The processing element may be configured to receive a message associated with a communication session with a network node, acquire service plan based capabilities associated with the network node, receive device based capabilities associated with the network node, and determine session based capabilities associated with the service based on the device based capabilities and the service plan based capabilities on a per subscriber basis. | 09-25-2008 |
