Patent number: 9307463Abstract: A user equipment UE determines that a neighbor cell is higher priority than a serving cell, measures neighbor cell signal strength in n>1 iterations, and analyzes them for reselecting from the serving cell to the neighbor cell. Each measurement iteration is spaced from one another by a time interval (e.g., 1 DRX) that is specific for the neighbor cell being higher priority. In various embodiments, the UE measures while in a Cell-PCH, URA-PCH or idle state/mode and the first iteration is taken at the first available measurement opportunity after transitioning to that state/mode. The UE reselects to the neighbor cell based on the analyzed signal strengths; in one embodiment the decision to reselect is without regard to signal quality of the serving cell; and in another the decision is without regard to whether a reselection condition remains satisfied for a specified time period Treselection.Type: GrantFiled: March 12, 2012Date of Patent: April 5, 2016Assignee: Xiaomi H.K. LimitedInventors: Brian Alexander Martin, Christopher Peter Callender, Stuart Ian Geary, Alexander Graham Charles, Steven Franklin, James Howard Tooley

Patent number: 9088953Abstract: A wireless device has a plurality of radio systems. The current priority of each of the radio systems is determined. An upper bound for the transmit power of each of the radio systems is set in dependence on at least the current priorities of the radio systems and a current maximum permitted transmit power of the wireless device. The upper bounds for the transmit power of each of the radio systems are variable over time and are set such that the sum of the upper bounds does not exceed the current maximum permitted transmit power of the wireless device. For each of the radio systems, the transmit power of that radio system is limited such that the respective upper bound for the transmit power for that radio system is not exceeded.Type: GrantFiled: June 11, 2013Date of Patent: July 21, 2015Assignee: BROADCOM CORPORATIONInventors: Andrew Bishop, Alexander Graham Charles, Stuart Ian Geary, Sami Jutila

Patent number: 8971961Abstract: A wireless device has a first SIM and a second SIM. The first SIM and the second SIM share a common radio system. A processing system determines whether to allocate use of the radio system to the second SIM for a time period that occurs when the first SIM is in an active connected mode using the common radio system in order to be able to at least one of transmit data and receive data. The processing system allocates or denies use of the radio system to the second SIM accordingly.Type: GrantFiled: September 9, 2011Date of Patent: March 3, 2015Assignee: Broadcom CorporationInventors: Andrew Bishop, Alexander Graham Charles, Stuart Ian Geary

Patent number: 8954111Abstract: A wireless device has at least a first radio system for a first SIM channel and a second radio system for a second SIM channel. A processing system is arranged to determine whether a first of the first and second radio systems is capable of providing service for both of the first and second SIM channels currently being serviced by the first and second radio systems respectively. Servicing of the second SIM channel is transferred from the second radio system to the first radio system if it is determined that the first radio system is capable of providing service for both of first and second SIM channels. At least a part of the second radio system is shut down to reduce the power consumed by the second radio system after servicing of the second SIM channel has been transferred.Type: GrantFiled: June 28, 2011Date of Patent: February 10, 2015Assignee: Broadcom CorporationInventors: Stuart Ian Geary, Nguyen Quan Tat, Andrew Bishop, Graham Alexander Charles, Roy Skovgaard Hansen

Publication number: 20130344918Abstract: A wireless device has at least a first modem and a second modern and at least a first SIM and a second SIM. The first modem supports a different level of service than the second modem. A processing system of the wireless device selectively reconfigures the connection of the first modem and the second modem to the SIMs. In a first mapping configuration, the first SIM is connected to the first modem and the second SIM is connected to the second modem. In a second mapping configuration, the second SIM is disconnected from the second modem, and the first SIM is disconnected from the first modem and is connected to the second modem thereby to obtain a different level of service for the first SIM than in the first mapping configuration.Type: ApplicationFiled: August 29, 2013Publication date: December 26, 2013Applicant: RENESAS MOBILE CORPORATIONInventors: Nguyen Quan TAT, Stuart Ian GEARY, Jari RUOHONEN, Andrew BISHOP, Sami JUTILA, Alexander Graham CHARLES, Roy HANSEN

Patent number: 8606216Abstract: A wireless device has two or more radio systems and SIM channels. At least a part of the first radio system can be shut down to reduce the power consumed by the device. This occurs if the first radio system is unable to obtain suitable service for the first SIM channel and the second radio system is at least one of: (i) providing at least some service on the second SIM channel for the device, and (ii) capable of searching for service for the first radio system.Type: GrantFiled: June 28, 2011Date of Patent: December 10, 2013Assignee: Renesas Mobile CorporationInventors: Stuart Ian Geary, Nguyen Quan Tat, Andrew Bishop, Graham Alexander Charles, Sami Jutila, Jari Juhani Ruohonen

Patent number: 8576901Abstract: A modem is provided for a wireless device that is capable of providing service for at least two SIMs. The modem has at least a first set of modem components and a second set of modem components. The modem selectively reconfigures the arrangement of the plural sets of modem components. In a first configuration, the first set of modem components provides wireless connection service for a first SIM of the wireless device and the second set of modem components provides wireless connection service for a second SIM of the wireless device. This allows active wireless connections to be made on behalf of both SIMs simultaneously by the sets of modem components. In a second configuration, the first set of modem components and the second set of modem components provide wireless connection service for the first SIM.Type: GrantFiled: February 29, 2012Date of Patent: November 5, 2013Assignee: Renesas Mobile CorporationInventors: Nguyen Quan Tat, Stuart Ian Geary, Jari Juhani Ruohonen, Andrew Bishop, Sami Jutila, Alexander Graham Charles, Roy Hansen

Publication number: 20130138983Abstract: The present invention introduces a method for saving power in battery limited devices. The invention handles profile properties, which may e.g. be User Interface activity, Bluetooth connection success, email fetch success or WLAN connection success. A value of the property is saved into a memory, e.g. once an hour for the whole calendar week, thus forming a trend value which is regularly updated. Certain behavior patterns may then be seen. When changes in the trend occur with different users or as differences compared to a usual behavior in a calendar week, for instance, the characteristics of the device are altered accordingly in order to minimize power usage.Type: ApplicationFiled: November 28, 2011Publication date: May 30, 2013Applicant: RENESAS MOBILE CORPORATIONInventor: Stuart Ian Geary

Publication number: 20120315910Abstract: For each of a plurality of received system information SI a cache entry is stored in a SI cache of a user equipment UE, each including at least some of the received SI, a timestamp of when the SI was first stored, and at least some of the cache entries also have relevance data relating the respective cache entry to one or more other cache entries. While the UE is in a state such as a CELL-FACH state (no dedicated physical channel allocated to the UE), a cache entry is selected for at least one neighbor cell, and that cache entry is related by its relevance data to the cache entry of the serving cell or determined from its timestamp to be in close proximity to the serving cell. The UE then identifies the selected neighbor cell in an uplink message as a suitable candidate for multipoint communications with the UE.Type: ApplicationFiled: June 8, 2011Publication date: December 13, 2012Inventors: Stuart Ian Geary, Steven Franklin, James Howard Tooley
