LTE (Long Term Evolution) defines the next 4G wireless communications standard, and delivers IP based services with assured Quality-of-Service (QoS) and seamless mobility. In addition to standard specifications on the air interface for UE and eNodeB, the 3GPP has also defined to the specifications to address the architectural issues on the access network. LTE also introduces high demands of data throughput and capacity (for example, each base station can deliver 100Mbps and support hundreds of users). It is much expected that the data bandwidth consumed by each subscriber will increase, while service plans will offer lower cost/MB and even flat rate for high volume users. Existing network architecture used to deploy 3G/HSPA data services have many issues and cannot be migrated to LTE: i) complex architecture with many network elements, introducing high network cost and high network latency, ii) constrained throughput, iii) cannot cost-effectively scale up. Therefore, the 3GPP standards introduce Evolved Packet System (EPS), which include the evolved access network architecture for LTE. The evolution of LTE technologies has created many opportunities for mid-size technology companies in the area to enter the LTE market. Rather than LTE macro base stations (called eNodeB), they can develop smaller scale base stations for picocell/femotcell to address niche market. However, for them to compete and to sell to the 2nd tier LTE network operators, they must offer a cost-effective LTE access network solution, which includes at least the eNodeB, access network elements and management systems. The mid-size companies have much advantage and great potentials in this market, such as cost advantage. The project aims to help these mid-size companies, by licensing the deliverable of this project to quickly develop their own LTE EPS solution. The deliverables will consist of cost-effective scalable control plane, data plane and management plane software based equipments in the LTE access network. This will greatly reduce the R&D cost, R&D risk and CAPEX to sell for the licensee. The project team’s experience, know-hows and framework from WiMAX ASN-GW and CWMS projects provide the critical foundation. At the same time, a publicly traded Hong Kong technology company, who has licensed the WiMAX ASN-GW has signed terms sheet to license the developed technologies.
