Patent number: 8433312Abstract: Method and apparatus for scanning a radio frequency band in a mobile communication device without knowing regulatory information. A processor of the mobile communication device utilizes a wireless transceiver to scan the RF band using a passive scan operation on an RF channel having a passive scan status. During the passive scan operation, the processor attempts to decode an information frame on the RF channel. In response to successfully decoding an information frame, the processor changes the passive scan status of the RF channel to an active scan status, and causes an active scan operation to be performed on the RF channel having the active scan status. The scanning process may continue until the regulatory information for the RF band is received.Type: GrantFiled: October 23, 2006Date of Patent: April 30, 2013Assignee: Research In Motion LimitedInventors: Leonardo Salomone, Michael Peter Montemurro

Publication number: 20130003632Abstract: A mobile device sends to a message a wireless network. The message indicates a plurality of different protocol types of broadcast messages to be processed as broadcast-to-unicast messages during a low power mode of operation of the mobile device. The protocol type of a given broadcast message is identifiable in a protocol identifier field of the broadcast message. The mobile device maintains its wireless receiver in a powered down state during the low power mode of operation while broadcast messages are broadcasted from the wireless network. For each broadcast message of each said indicated protocol type provided in the message sent to the wireless network, the mobile device monitors to receive via the wireless receiver a unicast message from the wireless network. The mobile device identifies broadcast message information of the broadcast message within the unicast message.Type: ApplicationFiled: September 12, 2012Publication date: January 3, 2013Applicant: RESEARCH IN MOTION LIMITEDInventors: Leonardo Salomone, Tom Nagy, Matt Milardovic, Arjuna Sivasithambaresa

Patent number: 8346247Abstract: A system and method are provided for monitoring the quality of a communication session with a mobile device. Should the communication session degrade, rather than dropping the communication session the user of a device communicating with the mobile device is prompted to wait while an attempt is made to improve the quality of the communication session. Similarly if the user of the mobile device moves out of a coverage area, rather than dropping the communication session the user of the device communicating with the mobile device is prompted to wait until a new communication session can be established.Type: GrantFiled: July 25, 2012Date of Patent: January 1, 2013Assignee: Research In Motion LimitedInventors: Leonardo Salomone, Rudy Eugene Rawlins

Publication number: 20120263070Abstract: In a Wireless Local Area Network (WLAN), roaming from one access point to another by a mobile station without interruption to network service may be facilitated by frequently performing background scans to find neighboring access points while the mobile station is associated to the WLAN. Frequent background scanning, however, depletes battery life. By dynamically adjusting the background scanning interval during the mobile station's association to the WLAN, the mobile station's immediate need for network connectivity performance may be met, while simultaneously prolonging battery life. For example, by using a shorter background scanning interval during a telephone conversation, network connectivity performance may be maintained throughout the call. Longer background scanning intervals may be used during periods when interruptions to network connectivity may be better tolerated.Type: ApplicationFiled: June 25, 2012Publication date: October 18, 2012Applicant: Research In Motion LimitedInventor: Leonardo Salomone

Publication number: 20110182276Abstract: Techniques for use in communicating messages to a mobile device operative in a wireless network are described. A communication network receives a broadcast message which includes a protocol type identifier in a protocol type identifier field. The communication network identifies whether the protocol type of the broadcast message matches one of a plurality of protocol types stored in association with an identification of the mobile device. If the protocol type of the broadcast message matches one of the stored protocol types, then the communication network produces, from the broadcast message, a unicast message which includes information from the broadcast message, and causes the unicast message to be sent to the mobile device in the wireless network.Type: ApplicationFiled: April 1, 2011Publication date: July 28, 2011Applicant: RESEARCH IN MOTION LIMITEDInventors: Leonardo Salomone, Tom Nagy, Matt Milardovic, Arjuna Sivasithambaresa

Patent number: 7953457Abstract: Methods and apparatus for use in reducing power consumption in battery-powered mobile communication devices in wireless local area networks (WLANs) are described. In one illustrative example, a mobile device in a WLAN is configured to normally refrain from receiving broadcast messages so that it may remain in a low power mode of operation. A network server is configured to convert broadcast messages into unicast messages for receipt by the mobile device only if the message or protocol type of the broadcast message is one in which the mobile device needs to process. As the mobile device is still configured to receive unicast messages, it will receive and decode such a unicast message and process the broadcast information within it accordingly. Advantageously, battery power is conserved at the mobile device.Type: GrantFiled: April 28, 2006Date of Patent: May 31, 2011Assignee: Research In Motion LimitedInventors: Leonardo Salomone, Tom Nagy, Matt Milardovic, Arjuna Sivasithambaresa
