Core Network ModernizationThe early core network was a closed and coupled system that relied on the proprietary hardware and closed architecture of equipment manufacturers. However, with the continuous advancement of technology, this closed nature has gradually become a shackle for development. The advent of the 2G/3G era brought about a technological innovation of "CT+IP" to the core network, achieving the separation of the media plane and the control plane, as well as a full IP-based transformation. This transformation not only enhanced the flexibility and scalability of the network, but also laid a solid foundation for subsequent technological evolution. The rise of packet domains, the weakness of circuit domains, and the emergence of IMS domains have brought brand-new business capabilities and application scenarios to core networks. In this transformation, Core-Net has gradually shifted from being a "big shot" in the industry to a recluse in the cloud. It is no longer as eye-catching as it used to be, but it quietly supports the operation of the entire network in a more efficient and intelligent way behind the scenes. Only when a large-scale malfunction occurs will people realize the importance of this hermit. However, it is precisely this unobtrusive support that enables the core network to continue to play an irreplaceable role in the 5G era.
The continuous evolution of core networks is leading an unprecedented communication revolution. Among them, "New Calls", as the brilliant pearl of this revolution, are gradually pushing traditional single-mode communication into a new era of multi-mode communication. Single-mode communication, with its simple and straightforward characteristics, has long met people's basic communication needs. However, this communication method that relies solely on hearing and vision has inherent limitations in terms of the accuracy of information transmission and the depth of understanding. Although video calls have enabled the transmission of audio and video between people, they lack support for environmental factors, emotional communication and deeper interaction, resulting in a relatively monotonous communication experience. The emergence of multimodal communication has completely broken this deadlock. It is not merely confined to the transmission of sound and images, but also extends communication to the dimensions of touch and environmental perception. Through the integrated application of advanced technologies such as wearable devices, controllers, tactile gloves, and cameras, multimodal communication can capture and transmit the expressions, gestures, movement states, and even environmental factors such as temperature, humidity, and altitude of the communication object during a call, thereby achieving a multi-object, multi-content, and multi-exchange communication experience. This brand-new mode of communication not only greatly enriches the dimensions of information transmission, but also profoundly changes people's perception and expectations of communication. In the 5G-A era, the continuous evolution of the core network provides strong technical support for the realization of "new calls". By introducing a more advanced network architecture, more efficient data processing capabilities and a smarter service management mechanism, the core network can easily handle the complex demands brought about by multimodal communication, ensuring the smoothness and stability of the communication process. At the same time, by integrating cutting-edge technologies such as artificial intelligence and big data, the new call can also achieve a more intelligent interaction experience, such as automatic translation, emotion recognition, and intelligent recommendation functions, making the communication process more considerate and convenient. |
