Abstract: Technology for method for reducing the number of unsuccessful service change attempts of a first mobile terminal is presented. The first mobile terminal is connectable via a mobile network to a further terminal by establishing a call connection for providing a first service or by establishing a call connection for providing a second service. The first mobile terminal receives a first indication signal indicating that a service change to the second service is temporarily unavailable from a mobile network node administrating an established call connection for providing the first service. In response to receiving the first indication signal, the first mobile terminal refrains from requesting a service change to the second service until reception of a further indication signal from the mobile network node indicating that a service change is available again.

Abstract: A line is deployed along a landing string or along a marine riser of a subsea well. The line has sensors, such as temperature sensors, distributed along its length. In one embodiment, the line comprises a fiber optic line that includes fiber optic temperature sensors distributed along its length. In another embodiment, the line comprises a fiber optic line used to transmit light, wherein the returned back-scatter light is analyzed to provide a temperature profile along the length of the fiber line. The fiber optic line can be deployed by connecting it to the landing string, pumping it down a pre-existing conduit (such as a hydraulic or chemical injection conduit), or pumping it down a dedicated fiber optic specific conduit.

Abstract: A method for reducing the number of unsuccessful service change attempts of a first mobile terminal is presented. The mobile terminal (1, 1a, 1b, 420) is connectable via a mobile network to a further terminal by establishing a call connection for providing a first service or by establishing a call connection for providing a second service. The method comprises the following steps performed by the first mobile terminal (1, 1a, 1b, 420): receiving (S21) a first indication signal (202) indicating that a service change towards the second service is temporarily unavailable from a mobile network node (31, 310) administrating an established call connection for providing the first service, and in response to receiving the first indication signal (202) refraining (S22) from requesting a service change towards the second service until reception of a further indication signal (204) from the mobile network node (31, 310) indicating that a service change is available again.

Abstract: A technique is provided for use by a user terminal or mobile services switching centre (MSC) for responding to a request to switch an on-going call from speech mode to multimedia mode within a wireless communication network conFig.d to automatically disconnect a call if a requested mode switch is not confirmed within a predetermined period of time specified by a call drop timer. In one example, the terminal or MSC activates an automatic response timer upon receipt of a request from a user to switch an on-going call from speech to multimedia, with the timer set shorter than the call drop timer. The user receiving the request is then prompted to accept or decline the request. If no response is received before expiration of the automatic response timer, the terminal or MSC automatically declines the request on behalf of the user so that the call drop timer does not expire.

Abstract: A process for the extraction of sucralose from an aqueous solution containing at least sucralose, other chlorinated saccharides, sodium chloride and dimethylammonium chloride into an organic solvent for sucralose by contacting said organic solvent with said solution to extract sucralose into the organic solvent. The ratio of sodium chloride to dimethylammonium chloride in the aqueous solution is increased prior to or during contact so as to increase the partition coefficient of sucralose into said organic solvent.

Abstract: A method of removing a carboxylic acid from a liquid that contains a tertiary amide solvent includes a step of contacting the liquid with an extraction medium comprising an amine. The amine is immiscible with both water and the tertiary amide solvent, and the contacting step forms a de-acidified phase containing the tertiary amide solvent and a phase containing the extraction medium and the carboxylic acid. Both the liquid that contains the tertiary amide solvent and the de-acidified phase may also contain a sucrose-6-acylate.
