CSPS Core Mobile Networks: An Overview
CSPS core mobile networks play a crucial role in providing voice and data services to mobile subscribers. These networks combine both circuit-switched (CS) and packet-switched (PS) technologies to handle voice calls, SMS, and data traffic.

Here are some key points about CSPS

core networks:
Circuit-Switched (CS) Domain:
The CS domain handles voice calls and SMS (Short Message Service).
It relies on traditional circuit-switching technology, where a dedicated path is established for each call.
CS services include voice calls, call forwarding, call waiting, and SMS.

Packet-Switched (PS) Domain:
The PS domain handles data traffic, including internet browsing, video streaming, and app communication.
It uses packet-switching technology, where data is broken into packets and transmitted over the network.
PS services include internet access, multimedia messaging (MMS), and mobile data.

Integration:
CSPS networks seamlessly integrate CS and PS domains to provide a unified experience for users.
Voice calls can be carried over the CS domain, while data services use the PS domain.

Evolution to All-IP Networks:
With the advent of 4G (LTE) and 5G, mobile networks are transitioning toward all-IP (Internet Protocol) architectures.
In all-IP networks, both voice and data traffic are carried over IP packets.
VoLTE (Voice over LTE) enables high-quality voice calls over the PS domain.

Cloud-Native Solutions:
Cloud-native solutions, such as NFV (Network Function Virtualization), are transforming CSPS core networks.
These solutions virtualize network functions, making them more flexible, scalable, and cost-effective.
Cisco, for example, offers the Cisco Cloud Services Stack for Mobility, which provides pre-integrated, cloud-native 5G core network functions1.

Operational Efficiency:
CSPs aim to simplify operations and reduce costs.
By adopting pre-validated solutions and leveraging NFV, they can streamline network deployment and management.
Cisco’s platform simplifies operations via a flexible subscription model, powered by proven technologies for 5G, IoT, and multicloud2.

In summary, CSPS core mobile networks are evolving to meet the demands of modern communication. They combine CS and PS technologies, embrace cloud-native solutions, and pave the way for seamless voice and data services.
