Different tunneling protocols are used depending on the interface. In both cases, the information is processed by the packet data convergence protocol PDCPthe radio link control RLC protocol and the medium access control MAC protocol, before being passed to the physical layer for transmission. The eNB sends and receives radio transmissions to all the mobiles using the analogue and digital signal processing functions of the LTE air interface. Each tracking area has two main identities.

procedures in LTE which includes basic registration, Carrier Aggregation ( band addition and removal), 4x4 MIMO activation, SMS etc. LTE MO SMS.
Delete session request can be send when UE is in Idle or Connected mode.
Data and signalling messages are carried on physical channels between the different levels of the physical layer and accordingly they are divided into two parts:.
LTE (Long Term Evolution) Tutorials and Call Flows
Following table lists the physical data channels that are used by LTE:. Logical Channels : Define whattype of information is transmitted over the air, e. Each eNB is a base station that controls the mobiles in one or more cells. There are four types of EPS bearers:. Priya KhiwalNetwork Engineer at Student.

Prepaid Charging - The CAMEL standard, which enables prepaid services in 3G, is not supported in LTE; therefore, prepaid customer information must be routed back to the home network as opposed to being handled by the local visited network. Show related SlideShares at end.
Instead system automatically recognizes the device, loads new drivers for the hardware if needed, and begins to work with the newly connected device.
This document, Part 2 of Initial Attach, discusses detailed initial attach procedures in EMM Case 1. EMM Case 1 concerns initial attach. 3GPPTM and LTE™ are Trade Marks of ETSI registered for the benefit of its Members and . Domains priority and selection for UE attempts to emergency call. Network initiated Mobile Originated (MO) connection. applications ranging from narrow-band to wide-band communications capability with integrated.

Which provides a tremendous savings in the amount of header that would otherwise have to go over the air. Physical data channels are distinguished by the ways in which the physical channel processor manipulates them, and by the ways in which they are mapped onto the symbols and sub-carriers used by Orthogonal frequency-division multiplexing OFDMA. Version Date UpdateV1. The main goal of LTE is to provide a high data rate, low latency and packet optimized radioaccess technology supporting flexible bandwidth deployments.
The eNB controls the low-level operation of all its mobiles, by sending them signalling messages such as handover commands. Each eNB connects with the EPC by means of the S1 interface and it can also be connected to nearby base stations by the X2 interface, which is mainly used for signalling and packet forwarding during handover.

|Prepaid Charging - The CAMEL standard, which enables prepaid services in 3G, is not supported in LTE; therefore, prepaid customer information must be routed back to the home network as opposed to being handled by the local visited network.
The interface is based on the Gx interface. Similarly, the physical channel processor creates physical signals, which support the lowest-level aspects of the system.
It then camps on the most suitable cell. Instead system automatically recognizes the device, loads new drivers for the hardware if needed, and begins to work with the newly connected device.
Each packet data network is identified by an access point name APN.
