What are the types of handover in LTE?

What are the types of handover in LTE?

LTE supports two types of handover: X2-based handover and S1-based handover.

What are the handover types in a fully UMTS network?

Within 3G UMTS there are several forms of handover including hard handover, soft handover, a form of handover called softer handover and a handover from one radio access technology to another called inter-RAT handover.

What are the different types of handover in GSM?

There are two types of handover. Soft handover and hard handover. Hard handover: hard handover is one in which the channel source cell is released before the channel in the target is engaged.

What is UMTS cell service?

UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per second (Mbps). UMTS is based on the Global System for Mobile (GSM) communication standard.

What is intra eNB handover?

Description. Inter eNB Handover (Source) Handover within an E-UTRAN. The procedure for when a UE is leaving a cell managed by the eNB and entering a cell managed by a second eNB.

What is intra FREQ handover?

Intra-Frequency Handover means mobility in connected mode between two different cells, but within same LTE frequency, This topic will be assigned for Event A3 which is used for LTE Intra-Frequency handover. Hyst: hysteresis, it is defined in eNodeB and used to avoid ping-pong handover.

What is Inter RAT handover?

Inter RAT Handover (Target) Handover from an E-UTRAN to a different RAT. The procedure for when a UE is entering the E-UTRAN cell. Intra eNB Handover (Source) Handover from one sector to another managed by the same eNB.

What is Active Set in UMTS?

Active set consists of those base stations which are connected with UE and soft handover region [15] is that region in which UE is connected with more than one base station.

What is intra MSC handover?

It is also known as Intra-BSC handover. Here the mobile moves from one cell to another but remains within the same BSC (Base station controller). Here the BSC handles the handover process. 3 Inter-BSC handover. It is also called as Intra-MSC handover.

What is inter MSC handover?

Handover between cells controlled by the same MSC is called Intra-MSC handover. On other occasions, a handover will be required in which a user will be handed over from a cell served by one MSC to a cell served by another MSC. This handover between MSCs is called Inter-MSC handover.

What are the different types of handover for UMTS?

For UMTS the following types of handover are specified: Handover 3G -3G (i.e. between UMTS and other 3G systems) FDD soft/softer handover FDD inter-frequency hard handover FDD/TDD handover (change of cell) TDD/FDD handover (change of cell) TDD/TDD handover Handover 3G – 2G (e.g. handover to GSM) Handover 2G – 3G (e.g. handover from GSM)

What are the different types of handover in mobile networks?

UMTS inter RAT handover: This form of handover occurs when mobiles have to change between Radio Access Technologies, e.g. UMTS to / from GSM or UMTS to / from 4G LTE, etc.. Each of the different types of handover is used on different occasions dependent upon the conditions.

What is hard handover in UE?

Hard handover means that all the old radio links in the UE are removed before the new radio links are established. Hard handover can be seamless or non-seamless. Seamless hard handover means that the handover is not perceptible to the user.
