Technological solutions for 4G

Adaptable Capability - Aware Service Provision	Different wireless access networks differ significantly in terms of coverage area and supported bandwidth, mobile network, their capabilities should be considered so as to refine the list of applicable services.
Transparent Mobility and Universal Roaming Capability	Seamless user mobility across different wireless access technologies (e.g. WLAN, UMTS etc.) with minimal or zero user intervention must be supported by efficient inter-system mobility management and hand over procedures. Roaming should build on cross industries standard protocols and architecture, such as hierarchical Mobile IPv6. As different systems may entail different charges, it should include QoS and pricing information as part of mobility management signaling.
Automated Protocol Configuration Mechanisms	The multiple options capable of accommodated the same set of services will result in accruing different charges in 4G mobile environments, thus users to be informed regarding the pricing preferences
Policy Based Management and Information Models	Policy based management demarcates between enforcer entities and decision entities in the infrastructure which results in realization of flexible management architecture that spans across multiple administrative domains. Policy protocols also support both outsourcing and provisioning modes of operation, making policy based management an ideal approach for 4G mobile environments.
Flexible Pricing and Billing Mechanisms	Network related pricing models must be completely independent from service related ones, with regarding to formulation as well as application matters.
Application and Mobile Execution Environment Aspects	As million mobile terminals and different manufacturers with different characteristics and applications will use 4G environment so there is a need to develop universal hardware platform with hassle free application with interpreted languages. The independent service provider will be relieved from the burden of developing, supporting and maintaining multiple versions of their applications for each possible client.
