Mobile phone apps able to work on all OSs instead of just one, the potential for Android to become a major OS and the promotion of ways to save energy were all major areas of focus at the Mobile Asia Congress organized by the GSM Association (GSMA) last week in Hong Kong.
Mobile apps are growing in popularity, due in part to Apple's success with the iPhone and the billions of apps already downloaded by users of the popular smartphone.
But while iPhone users number in the tens of millions, the GSMA hopes the potential to sell apps to 4 billion devices that use mobile phone networks around the world, and in particular the 1 billion people expected to subscribe to mobile broadband by 2012, will draw developers to a much wider market.
"The world of applications is just taking off," said Rob Conway, CEO of the GSM Association, during a speech at the congress. "Apps are going to explode in number and importance."
The trouble some GSMA members, particularly the mobile network operators, see is the inability of users to take their apps with them when they buy a new smartphone from a different vendor. Most app stores today focus only on one operating system, something mobile subscribers don't like, according to executives at the congress.
"In the world of applications we're missing what made mobile so successful, a common format," said Michael O'Hara, chief marketing officer of the GSM Association. He said people should be able to move their apps from one device to another, regardless of whether the operating system is different.
One way to make apps transferable to different devices would be to build an SDK (software developer's kit) for middleware for the global mobile network that will allow apps to be used on all devices, not just one, he said.
Dan Warren, director of technology at the GSMA, clarified in an interview that the proposed SDK is just an idea right now and that no concrete plans have been laid out.
Meantime, Mobile phone network operators are pursuing the creation of their own software standards and app stores as another way to play a larger role in apps. Their push to create standards stands out because GSMA's Mobile World Congress in Barcelona last February promoted apps from the perspective of software and device makers, such as Microsoft and Nokia.
The Mobile Asia Congress focused on network operators and their app plans, with an app conference, AppsXchange Asia, running at the same time as the congress, which focused on how to set up and operate an app store.
"Carriers have the strength of knowing our customers," said Ryuji Yamada, president and CEO of NTT DoCoMo, at the congress.
The Joint Innovation Lab (JIL), a joint venture established by China Mobile, Vodafone, Verizon Wireless and Softbank Mobile to develop software and services for their 1.1 billion mobile phone customers, is already hard at work on app and other software standards so their customers can use apps on a variety of devices offered by the carriers.
The group has set out software standards for widgets used on handsets and is working on a single platform for mobile apps, according to Masayoshi Son, chairman and CEO of Japan's Softbank, speaking at the congress.
Several major handset vendors have already agreed to support JIL initiatives in their mobile phones starting from the first quarter of next year, including LG Electronics, Research In Motion, Samsung Electronics and Sharp.
Another operator alliance has turned to Google's Android mobile OS.
The Conexus Mobile Alliance, which includes 240 million subscribers from companies such as NTT DoCoMo of Japan, KT Corporation of South Korea, Indosat Tbk of Indonesia and Far EasTone Telecommunications of Taiwan, last week announced the 13 finalists for an Android app development contest launched in June.
The group said the Application Development Campaign for Android was one of many initiatives the alliance has taken to promote the creation of more Android apps and encourage
