Founded in 1956, Roke Manor Research Limited is a UK company based at Roke Manor in Romsey, Hampshire. It is a contract research and development business for communications, networks, and electronic sensors. In addition to supporting Chemring, work is also conducted in both the public and private sectors. The company also created Hawk-Eye which is now used widely in sports such as tennis and cricket.Roke has been part of the Chemring Group since 2010, having been initially founded as part of the Plessey company and then subsequently owned for almost 20 years by Siemens.

Systems, methods and a mobile device for using policy defined by the operator to control the interfaces on which data is sent and received by the device are provided. The policy can be dynamically updated by the operator, by pushing new policy to the device for implementation. The policy can define that the device should switch certain data between two or more available interfaces at certain times, or when certain data may be sent or received over a particular interface. The device may receive new policy from the operator in order to help with the operators own operational objectives, such as traffic shaping or other traffic limitation to ease congestion or enforce service agreements. A policy implementing corresponding traffic limitation or shaping on the air interface between the mobile device and network base stations can be sent to the mobile device so as to reduce signaling congestion on the air-interface.

Roke Manor Research | Date: 2014-09-15

A method and apparatus for searching data for a pattern, the data being sent over a data-communication network, from a service, using a communication protocol. The method comprises the steps of receiving the data and generating a fingerprint associated with the data, the format of the fingerprint being based on the communication protocol and the content of the fingerprint being based on at least one characteristic of the data. The method also comprises the steps of identifying the data as belonging to a particular service and determining whether the data contains the particular pattern by comparing the fingerprint to a previously generated matching fingerprint. The method also comprises the steps of, if no previously generated matching fingerprint exists, selecting a pattern matching algorithm from a plurality of pattern matching algorithms based on the identified service and searching the data using the selected pattern matching algorithm.
