Alcatel lucent signs TD-LTE deal with Yoo Mee Africa

Alcatel-Lucent announced its TD-LTE deal with African telecom operator YooMee Africa to expand into new African market.
YooMee, previously known as 4G Africa, will deploy TD-LTE technology in its new markets within the next 6 months.
The telecom operator expects to build out in average 35 to 50 sites per capital city before deploying in remaining cities of the countries it operates in.
Peter Ziegelwanger, CTO of YooMee Africa, said that YooMee Africa selected Alcatel-Lucent because it brings a strong momentum in LTE as well as a competitive solution with a powerful IP-Centric ePC based on its 7750 Mobile Gateway.
Alcatel-Lucent will deploy TD-LTE solution consisting of eNBs, wireless backhaul and the evolved packet core (EPC).

EUTRAN

The E-UTRAN consists of eNODEBs which provide E-UTRA user plane and control plane (RRC ) protocol termination toward the user equipment. The eNBs are interconnected with each other by means of the X2 interface. The eNBs are also connected by means of the s1 interface to the evolved packet core (EPC).
FUNCTIONS WITHIN THE ACCESS STRATUM:
This provides the ability , infrastructure and accessibility to the UE in acquiring the capabilities and services of the network. The radio access protocols in the E-UTRAN access stratum are comprised of numerous functionalities:
1.     RRM performs radio bearer control, admission and connection mobility control and dynamic allocation of resources to UE’s in both uplink and downlink.
2.     Traffic management in conjuction with RRM supports real and non real time user traffic between UE and architecture side.
LTE network can be divided into control plane which is responsible for managing the transport and user plane which is responsible for transporting user traffic.

USER PLANE PROTOCOLS: this shows the protocol stacks for the user plane where PDCP,RLC,MAC and PHY sublayers perform functions like header compression, ciphering, scheduling.
