Abstract: Methods and apparatus are disclosed for sharing assistance information relating to an uplink signal transmitted by a first User Equipment. The assistance information may be used to assist a wireless communication device to intercept the uplink signal and measure its time of arrival. The assistance information may be used to assist in the calculation of a position or time, based on the measured time of arrival.

Abstract: A monitoring apparatus (116) for a network of communications-enabled devices includes: a processing resource (200) arranged to support a data selection module (214) and a data analysis module (216). The apparatus (116) also includes a communications interface (218) operably coupled to the processing resource (200) and arranged to receive a plurality of data fragments. The plurality of data fragments each bear a respective device identifier and associated observation data, the plurality of data fragments respectively including a plurality of unique device identifiers. The data selection module (214) is arranged to read the respective identifiers of the plurality of data fragments and the associated observation data and to identify a set of the plurality of data fragments generated as a result of a common device characteristic. The data analysis module (216) is arranged to analyse the set of the plurality of data fragments identified by the data selection module in order to detect anomalous device activity.

Abstract: Methods and apparatus are disclosed for sharing, by a first User Equipment, interception-assistance information relating to an uplink signal transmitted by the first User Equipment. The interception-assistance information may be used to assist a second User Equipment to intercept the uplink signal and measure at least one characteristic of it. Calculation-assistance information may be used to assist in the calculation of a position or time, based on the measured characteristic.

Abstract: Multiple data devices (A,B,C) are interfaced via a bus arbiter (S) with an external memory (F) so as to support burst-mode access by each device (A,B,C) one or more read registers (R1,R2,R3) are provided in the memory (F), and each register (R1,R2,R3) supports burst-mode access by a corresponding device (A,B,C). The arbiter (s) selects the register to be used following the initial access burst, according to the device requiring access. Thus, the memory (F) supports multiple burst-mode accesses in parallel.

Abstract: A wireless communications network participant comprising: a plurality of communications subsystems, each subsystem being arranged to transmit and/or receive signals under a different telecommunications standard; means for generating a clock signal; and scheduling means for sending commands to at least one of the subsystems for its or their operation, the scheduling means deducing the timing of the commands relative to the clock signal.

Abstract: An interrupt controller (1) is adapted to control the execution of interrupt requests (11, 12) of differing criticality by a processor (7) which is required to execute tasks (3, 17) of differing criticality under the control of a computer operating system (5); the interrupt controller being adapted to recognize critical (11) and non-critical (12) interrupt requests originating from different interrupt sources, and to recognize when the processor (7) is required to execute each of critical (3) and non-critical tasks (17); the interrupt controller being further adapted to pass critical interrupt requests (11) to the processor (7) for execution in preference to non-critical interrupt requests (12), to block non-critical interrupt requests (12) to the processor when they coexist with critical interrupt requests (11) or the processor (7) is required to execute critical tasks (3), and to pass non-critical interrupt requests (12) to the processor (7) when they do not coexist with any critical interrupt requests (11)

Abstract: A method of managing demand on a battery (26) of a mobile communications device (10) served by a network which defines a requirement relating to the behaviour of the mobile communications device (10), the method comprising assessing the status of the battery (26) and adjusting the behaviour of the mobile communications device (10) according to the status of the battery (26), such that the behaviour of the mobile communications device (10) departs from the network-defined requirement.
