What is the difference between soft and hard handover?

Hard Handover:- When mobile(in Call) switches to a new sector/Cell which is on different frequency , then it performs hard Handover. It is basically an inter-frequency handover. SOft Handover:- When mobile ( in Call) switches to a new sector/cell which is on the same frequency then it is called a soft handover.

What is hard handover?

A hard handoff is a handoff technique used with cellular networks that requires the user's connection to be entirely broken with an existing base station before being switched to another base station. ... A hard handoff is also known as a hard handover or break-before-make handover.

Why soft handover is not possible in LTE?

LTE is based on OFDMA, which is fundamentally a frequency division method. This means that a UE has to actually resync to a different set of frequency subcarriers when it hands over between cells, removing the possibility for soft handover.

What is 3g handover?

Handovers are an important part of every cellular communication system. They are used for providing mobility in cellular architectures. ... The whole process of tearing down the existing connection in the current cell and establishing a new connection in the appropriate cell is called “handover”.

What is the difference between soft and softer handover?

Soft handover - handover between two sectors of the same cell of a NodeB is called soft handover. Softer handover - handover between two cells (different NodeB) is called softer handover.

What is meant by soft handoff?

Soft handover or soft handoff refers to a feature used by the CDMA and W-CDMA standards, where a cell phone is simultaneously connected to two or more cells (or cell sectors) during a call. If the sectors are from the same physical cell site (a sectorised site), it is referred to as softer handoff.

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 handover and its types?

There are two types of handover which are as follows : Hard Handoff : hard handoff is the process in which the cell connection is disconnected from the previous cell before it is made with the new one. Soft Handoff : It is the process in which a new connection is established first before disconnecting the old one.

What is true for soft hand off?

Explanation: Soft handoff is one in which the channel in the source cell is retained and used for a while in parallel with the channel in the target cell. In this case, the connection with the receiver target is established before the connection to the source is broken, hence this handover is called make-before-break.

Which of handover does LTE support?

LTE supports two types of handover: X2-based handover and S1-based handover. The X2-based procedure is the least complex handover and typically would be used when an X2 interface exists between the source eNB and the target eNB.

What is LTE handover?

Abstract: Handover in LTE occurs when a device moves from the cell coverage serving it towards another; a process where the user established session must not be interrupted due to this cell change.

What is difference between handoff and handover?

Handoff is the process that occurs when a mobile is “handed over” from one access point to another, i.e., the access point which the mobile is using changes. Handover is the transference of authority, control, power or knowledge from one base station to another.

What is GSM handover?

Introduction: Handover or handoff refers to transfer of mobile connection from one resource (i.e. Base station, BS) to another BS without disconnecting the ongoing voice or data call. In GSM, mobile continuously monitors signal quality and signal power level of serving/neighbour Base Stations (BSs).

What is UMTS 3G?

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). ... Users will have access through a combination of terrestrial wireless and satellite transmissions.

What is blind handover?

Blind handover or redirection refers to that a base station directly orders a UE to switch or redirect to a certain target cell without requiring the UE to measure an adjacent cell and to report a measurement result.

What is sho in 3g?

Introduction: Soft Handover is one of the most interesting feature of the WCDMA operation. ... Please note that Soft handover procedure could include Radio link that belongs to the same Node B, different Node B but the same RNC or a Node B that belongs to dirrent RNC (Drift RNC).

What is horizontal and vertical handoff?

When a mobile station moves from one wireless cell to another wireless cell, it is a Handoff (or handover). It is classified as horizontal (intra-system) and vertical (inter-system). Vertical refers to the overlapping of wireless networks.
