LTE Protocol Stack

LTE Control Plane
The control plane consists of protocols for control and support of the user plane functions:-

  • controlling the E-UTRA network access connections, such as attaching to and detaching from E-UTRAN;
  • controlling the attributes of an established network access connection, such as activation of an IP address;
  • controlling the routeing path of an established network connection in order to support user mobility;
  • controlling the assignment of network resources to meet changing user demands.

The Communication between MME and S-GW, MME and MME is taken care by GTP-C v2. This is again used to communicate with other nodes in UMTS and GERAN networks too. Eloboration soon!
