Innovative development plan for the next generation mobile network
By the end of 2009, the number of global users in the mobile industry had exceeded 4 billion, generating revenue of more than $ 700 billion. In addition, Ericsson, the industry's leading mobile equipment supplier, expects to achieve 50 billion connections by 2020. Despite the current global economic downturn, this seems to have minimal impact on the mobile industry.
The mobile industry as a whole is expected to continue to grow, which is undoubtedly welcome news for all members of the wireless service sector. However, there is one thing we must pay attention to: the strong growth in this field is mainly concentrated in a specific field, that is-mobile data, which is largely due to the voice and text message (SMS) market in developed countries has reached Saturation is the reason.
Before making large-scale investments to upgrade mobile infrastructure, it is important to analyze the development trend of technology and clarify the most effective way to use investment resources. Therefore, it is necessary for us to understand which processors can best support future growth requirements. The new processor architecture must not only provide unified software support, but also have a high level of communication security.
LSI ’s revolutionary development plan for advanced communications processor infrastructure enables equipment manufacturers and service providers to fully address the challenges facing future mobile networks. LSI ’s solution integrates proven programmable scalable components as the foundation of the communications processor. The solution can help communications companies significantly increase their market share in this market with a market value of up to US $ 850 billion.
Market impact analysis
The two most important forces driving the continuous development of the communications industry are mobile service demand and mobile broadband access. From the above two aspects combined with the underlying processor or CPU technology to analyze mobile applications, it is not difficult to find related development trends of technology. On the one hand is the CPU core performance required by the application, on the other hand is the number of cores or threads required by the application. The combination of these two aspects can reflect the multi-faceted development trend of the processor market. Figure 1 shows a comparison of the unit core performance of various devices and the number of cores required. According to the intersection of analysis and application of the graph, we can draw the following conclusions:
1. Some applications depend on the CPU and require higher CPU functions. Such CPU-limited applications are usually pure control layer applications, such as xGSN control layer cards;
2. While other applications rely on threads, the processor needs to provide more threads. Such thread-dependent devices are usually classic data-layer-centric applications, such as transmission cards in RNC.
Figure 1 shows that a series of different applications have a balance of core performance and number of cores, which is the key to market success.
For example, to meet the requirements of mobile broadband, RNC user layer applications require a correct mix of user density, 4 to 8 cores per processor, and user peak throughput (CPU performance should be higher than 1.5GHz). Therefore, future communications processors must achieve the best balance between multi-core processors and powerful CPU cores.
Challenges in rebuilding network infrastructure
The mobile communication market needs multi-core processors to meet the development trend of consumer products. However, the current application range of multi-core solutions is limited and cannot fully meet the performance and flexibility requirements of future communications development. Figure 2 shows that the functions of current communication processors are either centered on the control layer or centered on the data layer, so they cannot effectively meet consumer demands for mobile services and data-intensive applications.

Security is another major challenge facing the mobile industry. The previous generation mobile phones used asynchronous transfer mode (ATM) communication to transmit data through a dedicated network, while mobile communication is currently switching to a public non-protected all-IP network. Therefore, equipment manufacturers and service providers must develop new methods to ensure customer privacy, which requires chip technology designers to make corresponding efforts to integrate security engines in the design scheme to protect data transmission through public networks .
LSI leads the industry development trend by providing innovative solutions
LSI has applied its extensive expertise in the network field to efficiently solve the challenges facing the mobile communications industry, thereby always maintaining its leading position in the industry. First, LSI's development plan will use proven high-performance computing cores. The processor core used will be based on the standardized instruction set architecture (ISA) to ensure that equipment manufacturers can use industry-standard development tools. The kernel will be compatible with widely deployed software libraries and support Symmetric Multiprocessing (SMP) architecture to further support the development of portable software architectures. Second, the LSI solution will use the Virtual Pipeline System-on-Chip (SOC) architecture, which is a super-efficient message transmission architecture that enables communication within and between processors. The Virtual Pipeline architecture supports the deterministic behavior necessary for next-generation network applications. Deterministic performance is required to meet the service level agreement (SLA) requirements, ensuring that network operators can predict the overall network performance of network nodes regardless of packet size, system load, or protocol type. Finally, the processor needs to be scalable to help equipment manufacturers implement LSI solutions for various network applications. Figure 3 shows the important advantages of the LSI multi-core solution.
Figure 4 shows how LSI multi-core processors meet the industry's forecasted development trends. The asymmetric multi-core solution not only enables the processor to complete data and control layer operations, but also enables the solution provided by LSI to free the gateway from the workload and meet the requirements of multi-core and single-core high-performance functions of enterprise routers. All key components can work together to help equipment manufacturers and service providers succeed in the dynamically developing mobile communications market.

to sum up
By analyzing the communications industry, we find that the traditional data layer and control layer functions of the current network have been difficult to meet the needs of mobile consumers. Device manufacturers and service providers must develop and implement a more robust and stable infrastructure to support mobile services and almost unlimited online content access. However, the current chip technology solutions are still difficult to support the future network operators to meet the dual requirements of achieving or even exceeding performance goals while reducing costs. However, the solutions provided by LSI use proven cores, innovative Virtual Pipelines SoC architecture and a highly scalable platform that can greatly simplify the changing needs of the communications market. LSI's asymmetric multi-core architecture strategy will become the industry's leading platform, helping service providers and equipment manufacturers to secure a victory in the future mobile communications market.
