Patent number: 10484860Abstract: A mobile communications terminal communicates data using a mobile communications network that includes base stations and mobility managers that can send and receive signalling packets for controlling user data communications between communications terminals and a destination. The communications terminal can communicate packets with the base stations via a wireless access interface provided by the base stations and send a signalling packet to the mobility managers, the signalling packet including user data intended for a destination, prior to establishing a signalling connection with the mobility managers. The mobility managers can, upon receiving a signalling packet from a communications terminal, detect the packet is not associated with any established signalling connection between the mobility managers and the communication device. The mobility managers can, responsive to the detection, transmit the user data in the signalling packet to the destination.Type: GrantFiled: June 5, 2017Date of Patent: November 19, 2019Assignee: SCA IPLA HOLDINGS INC.Inventor: Stephen John Barrett

Patent number: 10412693Abstract: A telecommunications system communicating data to/from one or more terminals, including one or more transmitters to transmit first and second carriers over respective first and second frequency bandwidths. During a first time period the transmitters can transmit data receivable by first and second classes of terminal on the first and second carriers. During a second different time period, the transmitters can transmit data to the second class of terminal on the first and second carriers in combination. A data transmission format on the first carrier in the first time period is incompatible with a user data transmission format on the second carrier during the first time period. The transmitters can transmit control data on the first carrier in the first time period which is receivable by the second class of terminal to enable the second class of terminal to maintain synchronization with the first carrier during the first time period.Type: GrantFiled: July 13, 2012Date of Patent: September 10, 2019Assignee: SCA IPLA HOLDINGS INCInventors: Peter Darwood, Martin Beale

Publication number: 20190141683Abstract: A method for communicating data between a base station and a terminal device in a wireless telecommunications system, for example an LTE-based system. The wireless communication system uses plural frequency sub-carriers spanning a system frequency band. Physical-layer control Information for the terminal device is transmitted from the base station using sub-carriers selected from across the system frequency band, for example to provide frequency diversity. However, higher-layer data for the terminal device is transmitted using only sub-carriers selected from within a restricted frequency band which is smaller than and within the system frequency band. The terminal device is aware of the restricted frequency band, and as such need only buffer and process data within this restricted frequency band during periods where higher-layer data is being transmitted. The terminal device buffers and processes the full system frequency band during periods when physical-layer control information is transmitted.Type: ApplicationFiled: December 17, 2018Publication date: May 9, 2019Applicant: SCA IPLA HOLDINGS INC.Inventor: Martin BEALE

Patent number: 10231224Abstract: A wireless communications system includes a base station, a plurality of intermediate devices, and a terminal device. Downlink communications may be provided directly from the base station to the terminal device, including control signals which instruct the terminal device where to send uplink data. This enables the base station to directly control scheduling of uplink communications, and in particular to define an uplink route from the terminal device to the base station via one or more intermediate devices. Power is conserved at the terminal device on the uplink because a lower power transmission can be used which although insufficient to reach the base station can reach the intermediate device. The terminal device is not required to determine the uplink path itself and therefore does not require complex, expensive, and power consuming control logic.Type: GrantFiled: November 4, 2016Date of Patent: March 12, 2019Assignee: SCA IPLA HOLDINGS INCInventor: Yuichi Morioka
