20080220800 | DATA-CAPABLE NETWORK PRIORITIZATION WITH REDUCED DELAYS IN DATA SERVICE - In one illustrative method, a periodic location update timer value is broadcasted by a wireless communication network and received and stored in memory of a mobile station. A request for data service is transmitted by the mobile station to a wireless communication network, and the request is reattempted at least one time in response to identifying a rejection of the request. If the request for the data service is accepted in response to the request, the mobile station operates in the wireless communication network using the data service. On the other hand, if the request for the data service is not accepted, the mobile station is set in a data service deregistered state. A timer is initialized with an initial value that is less than the periodic location update timer value and started. In response to an expiration of the timer, the mobile station repeats the transmission of the request for the data service and any reattempts in response to any rejections of the request. If the periodic location update timer value is less than the initial value, however, the timer is initialized with the periodic location update timer value. | 09-11-2008 |
20110034199 | METHOD AND SYSTEM FOR MAINTAINING A WIRELESS DATA CONNECTION - A system and method for establishing and maintaining an “always-on” data connection to a wireless network through the use of a back off timer and a service check timer is disclosed. The back off timer is initialized to a determined value when a connection is not established. When the timer expires, a connection attempt is made. As further connection attempts are made, the back off timer is set to ever-increasing values. When the data connection is established, the service check timer is initialized. The data connection status is determined at the expiry of the service check timer. When, at the expiry of the service check timer, the data connection is determined to be lost, the connection method is employed. | 02-10-2011 |

20120270588 | METHOD, APPARATUS, AND SYSTEM FOR INITIALIZING COGNITIVE SYSTEM SUPPORTED BY COGNITIVE PILOT CHANNEL - The present invention discloses a method, an apparatus, and a system for initializing a cognitive system supported by a cognitive pilot channel, where implementation of the method includes: sending a frequency initialization request message to a CPC AP; receiving a frequency initialization response message sent by the CPC AP, where the frequency initialization response message includes CPC private resource description information; broadcasting cognitive information of a base station and description information of an uplink access channel to a terminal over a channel specified in the CPC private resource description information; receiving cognitive information of the terminal over CPC private resources, deciding a work frequency according to the cognitive information of the terminal, and sending the decided work frequency to the terminal; establishing, on the decided work frequency, a link with the terminal. . | 10-25-2012 |
20130178239 | SYSTEM AND METHOD TO FACILITATE TIME MANAGEMENT FOR PROTECTED AREAS - Spectrum that will become venue-protected in the future is made available to radio devices by a central control system with which the radio devices requests spectrum access information for use in wireless communication. The central control system establishes a re-request time duration specified in an amount of time that will elapsed at or before the spectrum becomes protected. The elapsing of the re-request duration serves as a command to the radio device to transmit a new channel request to the central control system | 07-11-2013 |
20130225221 | Method and Apparatus for Transfer of Radio Resource Allocation - In accordance with an example embodiment of the present invention, an apparatus comprising a transmitter configured to transmit a message releasing radio resource, a receiver configured to receive one or more requests for acquisition of at least part of the released radio resource and a controller configured to defer grant of any request for radio resource acquisition if more than a predetermined number of requests is received within a predetermined time window. | 08-29-2013 |

20140315591 | COMMUNICATION TERMINAL DEVICE, COMMUNICATION SYSTEM, AND METHOD OF CONTROLLING COMMUNICATION TERMINAL DEVICE - A communication terminal device includes the following units. A detection unit detects a control signal instructing start of registration processing. A channel selection unit selects at random, from a plurality of frequency channels, the first frequency channel to be used in transmission of a beacon request when the control signal is detected. A scan control unit transmits the beacon request to the control devices by using the selected frequency channel. A receiving unit receives the beacon signal transmitted from each of the control devices. A list storage unit stores a predetermined parameter included in the beacon signal and the frequency channel in association with each other. A registration control unit transmits a registration request signal to the control device. | 10-23-2014 |
20150038188 | Task Processing and Resource Sharing in a Distributed Wireless System - The present disclosure discloses a system and method for task processing and resource sharing in a distributed wireless system. The system includes a processor and a memory storing instructions that, when executed, cause the system to: identify a plurality of nodes in a distributed wireless system, each node of the plurality of nodes associated with a radio frequency neighborhood, the radio frequency neighborhood of one node including one or more other nodes that hear beacons from the one node; assign a task to the plurality of nodes; split the task into a plurality of subtasks; assign the plurality of subtasks to the plurality of nodes; receive a plurality of subtask processing results from the plurality of nodes; and combine the plurality of subtask processing results to generate a task processing result for the task. | 02-05-2015 |
