Abstract: Along with the deployment of 3G networks and the launch of diversified mobile Internet services, network service modes and operation modes have greatly changed, and now the smart phone plays a key role. Accordingly, the key technologies for the smart phone, such as the application security management framework, application software authentication mechanism, interoperating capability and dynamic power management should be paid much attention to. The mobile phone vendors are gradually transforming into platform providers who will offer the support for services, including hardware, protocol stacks and storage, instead of providing specific services. Meanwhile, operators and Internet service providers will become the main body of service development.
