What is Uplink CE Congestion?

Congestion in CE (Channel Element) in Uplink is calles Uplink CE Congestion.In 3G network mostly CE congestion observed in Uplink Direction.

What is CE(Channel Element)?
A band Channel Element is the resource base required in the Node-B to Provide for one voice channel capacity, including the control plane to Provide for one voice channel capacity, including the control plane signaling, compressed mode, the transmit diversity and softer handover. “signaling, compressed mode, the transmit diversity and softer handover.

CE(Channel Element Utilization)?
Its depend on Vendor to Vendor Ericsson,Huawei and NSN have different CE utilization ratio.

For Exapmle:

CE Utilization

From Figure It clearly shows as compare to Downlink CE consumption is two times more.
Its main reason for Uplink CE Congestion in 3G.

Solutions for Uplink CE Congestion:

  • Upgrade the CE license according to your vendor.
  • R99 services uses more CE so try to reduce R99 services.There are several parametrs which can help R99 Service utlization optimization.
  • Load Balacing between 2G and 3G or 3G and 4G can also help to reduce Uplink CE Congestion.

We can avoid CE Congestion in initial network planning by Proper Dimensioning.
