Always Connected … With or Without A Network

The Challenge
Communication networks are extending their reach, evolving into hybrid IP networks, combining the bandwidth of WiFi and the coverage (ubiquity) of a 2.5G cellular data network. This coexistence, between wireless IP technologies, makes the hybrid network a potentially cost effective alternative to 3G for pervasive wireless access. At a fraction of the cost of a similar 3G network, the hybrid network is already able to provide ALL of the 3G services TODAY.

The Solution
There are synergistic opportunities in meeting these challenges:

(a) coalescing the fragmented hotspot market increases footprint coverage and market acceptance as a credible access platform; unifying hybrid networks into a seamless service for customers defuses expectation gaps in coverage and bandwidth, and generates

(b) a higher (albeit shared) data traffic; tailoring a range of new user experiences found in personalized, location based, time critical and collaborative networking

(c) services, that represents the different access and bandwidth opportunities within a hybrid network, helps to retain customers and enhances revenues.

SONaccess Modules
Network-based Software Modules

a) SONaccess Gateway - Access Controller Module, an intelligent access controller software providing multiple user authentication schemes and accounting methods to support the network provider’s revenue model.

b) SONaccess Gateway - Foreign Agent Module is the Foreign Agent (FA) component of the Mobile IP protocol located at the edge of a service provider's network being "visited" by a roaming mobile user. It is the mobile user’s temporary index router that assists the user in informing his home network of his current care-of-address (COA) and thereby receiving all packets addressed to him at his home network.

c) SONaccess Gateway - Location Based Service (LBS) Module which enables the provision of location-dependent, personalized and value-added services to mobile users in a wireless LAN environment.

d) SONaccess@Home is the Home Agent (HA) component of the Mobile IP protocol. It is located on the user's home network (which may be located within a service provider's network or within an enterprise network) and is constantly being informed of the mobile user’s current location, as represented by his COA. The HA is thereby able to forward all packets to the user’s current location.

Client-based Software Modules

SONmobile is a Mobile IP client software installed onto mobile devices to provide them with the unique ability to maintain sessions, regardless of movement between locations on different networks. It maintains a continuous communication with the user’s home network using only the one same (permanent) home IP address at each point of attachment to the network as the user moves from network to network. In its essence, SONaccess enables the network provider to better manage user access into its hybrid network and supports various user-specific LBS revenue models, over and above the critical seamless handoff between and within the different IP based networks, across multiple access points and access technologies.

Secure Access
The Advantage

Network security begins with network access; usually from the edge of the provider’s network. SONaccess includes an intelligent multi-functional access controller (AC) module and Mobile IP agents that address common network access, network security and service deployment issues of network providers. SONaccess servers represents the first line of defense against unauthorized access; providing simultaneous support for multiple authentication mechanisms that work seamlessly with different networks of service providers, offering multiple charging/billing methods. SONaccess features both web-based and port-based authentication schemes that support all EAP authentication methods; supports both RADIUS and DIAMETER AAA and interoperates with major third party VPN solutions for secure access to internal corporate networks.

Secure Seamless Mobility

SONaccess provides persistence or continuity of the user’s online application (session) when moving in and out of different participating IP networks, whether from WiFi to WiFi or WiFi to a GPRS or CDMA network. This seamless mobility is painless and hassle-free, without the need for any manual user intervention or network changes required of the WAN provider. The home network (represented by a Home Agent) monitors the mobile user’s points of attachments (represented by a Foreign Agent at each visited network) as the user roams across different wired and/or wireless IP networks, and re-routes all IP traffic destined for the user to his current location. In a commercial deployment, SONaccess provides added security by requiring authentication of the user to access the network and accounting for their usage thereafter as the user roams amongst participating networks.

Location Based Services

Relevant and personalized information makes for compelling applications that retains a user’s interest and keeps the user connected to the network. SONaccess combines it unique seamless roaming solution with its LBS module to enable network providers to push specific services and personalized information of interest to the mobile user based on the user’s proximity to these location or services. Effectively, SONaccess enables the combination of the mobile Internet, mobile commerce, multimedia content and location based services, to personalize the user’s mobile experience.

Key Benefits

• Mix-and-Match Flexibility. By co-locating several SONaccess modules into a single select hardware platform, SONaccess seeks to reduce the network complexity and thus the multiplicity of network devices required at the edge of the network. This limits maintenance to a single point of failure and allows network providers to better manage their up front investment cost while providing "mix-and-match" flexibility of their network access services.

• Complete Family Of Products. SONaccess promises a complete mobile Internet infrastructure solution for network operators and enterprises alike.

• Scalability : The Dynamic Home IP assignment feature of SONaccess@Home allows the Radius Server to efficiently distribute the load of the MobileIP traffic among several Home Agents.

• Carrier Class Redundancy : Besides the power supply redundancy, SONaccess also supports VRRP for eliminating single point of failure that can halt existing sessions.

• Standards-Based Inter-Operatability : SONaccess products are based on IETF and other industry standards to guarantee its inter-operatability with Home Agent and Foreign Agent routers from major vendors.
