Data Offloading - LTE and 3G networks

The ever increasing demand for higher bandwidth has made it imperative to employ innovative offloading solutions to access the public IP networks at a lower cost and ease of use. It will enable cellular network operators to retain the subscribers and provide them services at lower cost by reducing the load on the core network. This will also help in maximizing returns on the scarce and expensive cellular (3G/4G/WiMAX/CDMA) radio spectrum by offloading users from it to the inexpensive Wi-Fi technology, thereby helping operators to avoid the cellular spectrum CAPEX costs. Wi-Fi is an inexpensive and ubiquitously available technology that makes it an ideal choice for offloading data in cellular networks.

Data Offloading - LTE and 3G networks

The ever increasing demand for higher bandwidth has made it imperative to employ innovative offloading solutions to access the public IP networks at a lower cost and ease of use. It will enable cellular network operators to retain the subscribers and provide them services at lower cost by reducing the load on the core network. This will also help in maximizing returns on the scarce and expensive cellular (3G/4G/WiMAX/CDMA) radio spectrum by offloading users from it to the inexpensive Wi-Fi technology, thereby helping operators to avoid the cellular spectrum CAPEX costs. Wi-Fi is an inexpensive and ubiquitously available technology that makes it an ideal choice for offloading data in cellular networks.

Network Equipment Manufacturers can develop highly effective Wi-Fi offloading solution that can help reduce CAPEX and OPEX requirements.Using Wi-Fi offloading solutions for technologies such as 3G, LTE, WiMAX and CDMA cellular operators can provide common identity to UEs for cellular and Wi-Fi access through their SIM and thus provide common billing. 

Aricent has a features-rich carrier grade software offering that can enable OEMs to develop highly scalable standard compliant Wi-Fi offloading solutions that can support both trusted and untrusted Wi-Fi networks.

  • Wi-Fi offloading provides cost-effective solutions to subscribers and to reduce load/congestion on core network and improve ROI
  • MVNOs and MNOs, both gain with the cost effective and scalable Wi-Fi offloading solution for cellular networks (LTE, WiMAX, 3G and CDMA)

Features

  • Supports untrusted (ePDG/TTG) and trusted (SaMOG/TTG) Wi-Fi deployments
  • User authentication support - EAP-relay between IKEv2 and AAA server
  • Multiple PGW/GGSN support
  • Support for IKE/IPSec (for ePDG/TTG) and EAP/Radius (for SaMOG/TTG)

Use Cases

Wi-Fi Offloading has many use cases. Some important ones are:

  • Wi-Fi Calling–Use Wi-Fi interface to make calls over Wi-Fi
  • Applications during Roaming–MVNOs who want to offer proprietary applications can Wi-Fi offloading as the data connection can be offered through home networks which is offered by the MVNO.
  • Connectivity in Stadiums – In stadiums where handovers are not high speed, but data bandwidth is large, operators can deploy Wi-Fi offload for these deployments
  • Offering Coverage for Black Spots – Operators who do not have nation-wide coverage for wireless, can enhance their coverage by offering Wi-Fi offload in such areas

Benefits

  • Reduces load on limited licensed spectrum to reduce cost and enhance customer satisfaction
  • Enables partial offloading for non-real time data like Internet browsing can be offloaded to Wi-Fi to address excess demand
  • Provides support for high-speed backhaul
  • Allows seamless handover between Cellular and Wi-Fi
  • Enables common Charging for Cellular and Wi-Fi
  • Permits authentication based on SIM even while on Wi-Fi
  • More bandwidth available on Cellular due to offloading
  • Subscribers gain by cheaper rates
  • Same identity preserved
  • Can make calls even on roaming
  • Subscribers do not move away from operator networks
  • Operators can offer ads and other modes to gain revenue
  • No separate subscription
