Wireless internetworking protocol
For wireless networking, wireless internetworking protocol (WIP) designed to provide reliable and continuous data transfer flow in the Internet protocol (IP) layer over wireless communications systems.This technology enables the wireless hosts to be mobile while providing soft handoffs of high quality of service (QoS) for real-time data traffic over mobile wireless networks. WIP enables make-before-brake soft handoff procedures, which enables end-to-end reliability through maintaining transport control protocol (TCP).It solves some basic problems such as such as the triangle routing problem and the requirement of redundant buffering, comparing and transferring of stacks of data.
Interworking Requirements:
The design for the interworking scheme between DECT and ISDN equipment is shown It is shown that, the page link between the ISDN NT and the TE is provided by the
DECT Radio Fixed Part (RFP) and wireless portable part (WPP).
Ambient networks
This architecture allows creation of innovative network solutions for mobile and wireless systems beyond 3G. Network entities interact with the new control space through three interfaces:
1.Ambient ServiceInterface (ASI) to access a subset of the control space
functionality
2.Ambient Resource Interface (ARI), to access multi-radio resource management, mobility and trigger processing.
3. Ambient Network Interface (ANI) facilitates communication between the control spaces of different networks, creating the shared, common control space that enables
the advanced internetworking capabilities.
Connectivity Abstractions
Ambient Networks enable interoperation of legacy networks by providing a number of identical communication primitives independent of the underlying connectivity technology.
MULTI-RADIO ARCHITECTURE IN AMBIENT NETWORKS
An all in one flexible architecture considering all existing and future radio access technologies, and supporting different levels of coordination depending on operational modes.It has two parts:
1.Multi-Radio Resource Management (MRRM) for joint management
of radio resources and load sharing between the different
RAs;
2.Generic Link Layer (GLL), which provides a toolbox for unified page link layer processing, offering a unified interface towards higher layers and an adaptation to the underlying
radio access technologies.
