In today's podcast: Samsung's profit, UK mobile ad spending and Vertu's smartphone range are all increasing.

Meanwhile HTC's profit and the proportion of children with mobile phones are both going down. Discover the background to these news stories - and plenty more - in our regular weekly broadcast.

Communications infrastructure business Alcatel-Lucent has revealed plans to cut around 10,000 jobs by the end of 2015. It’s part of a company-wide commitment to save €1 billion in the same period.

These actions, which form part of ‘The Shift Plan’ announced in June by new CEO Michel Combes, are designed to reposition Alcatel-Lucent as a ‘next generation’ technology specialist and return it to profit.

The amount of money spent on mobile-based advertising in the UK grew by 127% year-on-year to £429.2 million in the first half of 2013.

It means that 14.1% of all digital advertising spend is now targeted at mobile devices, which is nearly double the same period last year.

LG Electronics has announced a business-focussed security service called LG GATE. It’s designed to separate a user’s own personal data from company data on their smartphone.

The platform is being launched in the USA on the new LG G2, enabling companies with a ‘bring your own device‘ policy to give their staff secure access to enterprise data via a personal smartphone.

Talk about a difference. In preliminary results last week, HTC announced its first-ever quarterly loss while Samsung revealed record quarterly profits.

Curiously, many of the week’s other news stories also had a companion headline to provide a contrast.
