# From 5 MHz how much % of resource occupy by CS traffic and how much by PS traffic?

Hello Experts.

How to calculate CS and PS resource consumption % for a cell in 3G?

We want to calculate from 5 MHz how much % of resource occupy by CS traffic and how much by PS traffic?

Vendor: Huawei.

Which resources?

TCP / Code / CE / License / Number of users?

I think you can compare ENU users with HS users, but it’s not gonna give you an accurate estimation.

UMTS capabity estimation is a little bit complex study to calculate because of there several different resource under two main different capacity.

1. Soft capacity (UL Power and Code)

2. Hard Capacity (DL Power and Channel Element)

For GSM it is less complex.

Directly count your TRX timeslot and check if you using dymanix or static pdtch, and get traffic for voice or GPRS and use erlangB table and formulate it that is all, you can understand each service consumption ratio.

3G is more complex than 2G because 3G has many different resources.

But 2G only has the Trx resources

For CDMA technology you don’t need calculation.

There is unlimited capacity

It don’t have single calculation formula, it is including many key factors to calculate it.

The allocation of resources between Circuit Switched (CS) and Packet Switched (PS) traffic in LTE networks can vary based on network configuration, operator policies, and user demand.

The percentage of resources dedicated to CS and PS traffic depends on factors such as the number of active users, the type of services being used, and the network capacity.

In LTE, CS traffic typically refers to voice calls using circuit-switched fallback (CSFB) or voice over LTE (VoLTE), while PS traffic includes data services like internet browsing, streaming, and other packet-switched applications.

As of my knowledge cutoff in January 2022, it’s challenging to provide an exact percentage without specific details about the network deployment and operator policies.

However, in LTE networks, there is a general trend toward increasing the share of resources allocated to PS traffic, reflecting the growing demand for data services.

To get accurate and up-to-date information on the resource allocation between CS and PS traffic in a specific LTE network, you may need to consult with the network operator, review their documentation, or analyze network statistics and reports.

Operators often use network management systems to monitor and optimize resource allocation based on real-time traffic patterns and user demand.

In UMTS (Universal Mobile Telecommunications System), the resource allocation between Circuit Switched (CS) and Packet Switched (PS) traffic is also influenced by various factors, including network configuration, operator policies, and user demand. UMTS is a 3G technology that supports both circuit-switched voice and packet-switched data services.

Similar to LTE, the percentage of resources allocated to CS and PS traffic in UMTS networks can vary. However, as a general guideline, voice services typically use circuit-switched resources, and data services use packet-switched resources.

In UMTS, voice calls are often carried over circuit-switched connections using Dedicated Channels (DCHs), while data services, including internet browsing and messaging, use Packet Data Channels (PDCHs) for packet-switched communication.

The specific allocation of resources between CS and PS traffic can be influenced by factors such as the number of active voice calls, the demand for data services, and the overall capacity planning of the network.

Operators may dynamically adjust resource allocation based on network traffic conditions.

To obtain precise information about the resource allocation in a specific UMTS network, you would need to refer to the documentation provided by the network operator or consult with the operator’s engineering team.

They may have network management systems and tools in place to monitor and optimize resource allocation based on real-time traffic and user behavior.
