Abstract: The invention relates to a method and apparatus for controlling one or more characteristics of a service received by a mobile station in a mobile communications network across a radio communications link with a dynamically varying bandwidth. Bandwidth-sensing data packets are created for the purpose of determining changes in the bandwidth available across the link and transmissions of bandwidth-sensing data packets across the link are monitored. If timing information generated from the monitored transmissions indicates a change in the bandwidth, then one or more characteristics of the service received can be altered.

Abstract: A service node is provided in a mobile communications network which collects radio link measurement reports which are transmitted to the service node by mobile stations. The mobile stations transmit the measurement reports in encapsulated form, in the form of SMS messages, in order to prevent the interception of the measurement report by the serving base station. The service node is able to perform handover decision algorithms using the measurement reports collected from the mobile stations in order to determine appropriate radio access nodes to be allocated to the mobile stations.

Abstract: A mobile handset for use in a mobile communications system includes a user interface, a radio communications front end, a radio transceiving antenna, and a browser application to interpret a multimedia document received from a remote server. The browser application recognizes textual presentation markup tags in the document and presents text to a user in accordance with the markup tags. The browser application recognizes a standard set of document-independent local library file markup tags in the document, and stores a standard set of non-textual local library files corresponding to the local library file markup tags. The browser application further presents content provided by one of the local library files via the user interface in response to the recognition of one of the local library file markup tags in the document.
