Backing this is unmatched experience with IP networks, derived from leading roles in several of the world’s largest networktransformation projects. A broad portfolio of services – These offerings can assist you through every stage of service planning, deployment and maintenance. They include: • End-to-end integration, leveraging existing infrastructure wherever possible to optimize economies. • WiMAX business and network consulting to help you evaluate different approaches to new opportunities • Site location/acquisition and construction resources to turn your wireless network plans into reality • Managed operations and maintenance, which allows you to focus on the market Alcatel-Lucent End-to-End IP Wireless-Broadband Solution for WiMAX 9 To maintain reliable performance for real-time applications, such as voice over IP and video, the Alcatel-Lucent WiMAX solution manages QoS dynamically, with traffic prioritization across all network levels. Starting with the request from the end-user device, each network level communicates with the others to determine the required QoS level for the session. Then it dynamically checks the network resources available, based on the rights of the subscriber. And finally, packets are tagged accordingly, establishing end-to-end flows. The result is outstanding QoS. The Alcatel-Lucent WiMAX solution has recorded a voice-quality Mean Opinion Score of 4.1 out of 5.0 in urban field deployments – a higher level of quality than demonstrated with top-quality GSM codecs under ideal radio conditions. However, IP traffic is much less predictable than in past wireless or cellular networks. The Alcatel-Lucent End-to-End IP Wireless-Broadband Solution for WiMAX goes even further, incorporating latest innovations from Bell Labs to give unprecedented QoS/QoE guarantees. The Alcatel-Lucent 9900 Wireless Network Guardian is the first product on the market providing simultaneous, realtime visibility over every link of the wireless broadband network where overload could cause the network to crash.

Dynamic QoS managed across the network Whereas operators are often attentive to high IP bandwidth consumption such as P2P file-sharing behaviors, airtime and signaling resources can also become exhausted. Leaving VPN connections open for hours when totally unused, for example, can eat up scarce airtime resources in the cell, and mobile e-mail delivery devices create signaling loads disproportionate to the light IP capacity they require. The Alcatel- Lucent 9900 Wireless Network Figure 4. Innovative radio resource visibility, Alcatel-Lucent 9900 Wireless Network Guardian Guardian provides full visibility into how real end-user behaviors impact network utilization, enabling QoS adjustments in real-time and better network planning. This represents a first step into deep packet inspec tion technology. The Alcatel-Lucent End-to-End IP Wireless-Broadband Solution roadmap calls for integrating application-assurance capabilities, such as tiered service quality, into the solution using Alcatel-Lucent service-edge routers in the near future.

The Alcatel-Lucent 8610 Instant Convergent Charging software suite enables flexible options for growing a subscriber base: prepaid accounts (scratch card or voucher), instant online sign-up, as well as traditional post-paid accounts from its onset. For existing operators, it allows federation of all charging platforms into a single easy-to-manage database, lowering OPEX. The real-time charging platform also allows operators to reduce OPEX on customer-care call centers, with Web- based self-care. This payment system is ready for service evolution to interactive media and Web-based self-service, and the Alcatel-Lucent End-to-End IP Wireless-Broadband Solution roadmap includes future options to introduce content-based charging. Alcatel-Lucent End-to-End IP Wireless-Broadband Solution for WiMAX 11 With the Alcatel-Lucent End-to-End IP Wireless-Broadband Solution architecture, you can activate more advanced ...
