What is handover process in LTE?
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 kind of handover techniques are supported by LTE for various services?
Types of Handover in LTE network Intra-LTE Handover: In this case source and target cells are part of the same LTE network. Inter-RAT: Handover between different radio technologies. For example handover from LTE to WCDMA.
What are four types of handover occurring in GSM?
GSM Handover from Network Side
- Intra-BSC handover: This handover type is serviced between cells served by same BSC. •
- Inter-BSC handover: This handover type is serviced between cells served by different BSCs. •
- Inter-MSC handover: This handover type is serviced between cells served by different MSCs.
How many types of handover happens in GSM?
Within the GSM system there are four types of handover that can be performed for GSM only systems: Intra-BTS handover: This form of GSM handover occurs if it is required to change the frequency or slot being used by a mobile because of interference, or other reasons.
What is intra eNB handover?
Intra E-UTRAN Handover is used to hand over a UE from a source eNodeB to a target eNodeB using X2 when the MME is unchanged.
What is inter 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. Inter eNB Handover (Target)
What is S1 handover in LTE?
An S1 handover is a fallback for scenarios where X2 interface is not available. As the name suggests, S1 handovers take place over the S1-interface. The MME and the SGW are involved during the handover procedure.
What is different types of handover in mobile computing?
There are two types of handover, vertical and horizontal. Horizontal handover occurs when a device moves within one type of network technology under one operator. For instance a mobile phone user moving within their provider’s network must switch cellular towers as they move in and out of range of different towers.
What is intra BSC handover?
Intra BSC Handover. • Or named as Inter BTS Handover • Occures when moving from one BTS coverage area into another BTS • Both BTS are controlled by the same BSC • The BSC assigns the new channel and slot for the ME.
What is LTE inter-technology handover?
Inter-Technology Handover means mobility in connected mode between two different cells and different technology. This topic will be assigned to Event B1 which is used for LTE Inter-Technology handover. This event type is also known as Inter-RAT or Inter-System handover.
How many types of handover approach available in mobile networks?
Normally there are two type of handover approach available in mobile networks. Network Controlled: In this case network makes handover decisions. Mobile Evaluated: The UE will make handover decisions and inform network about it.
What is handover in 4G?
1. . 4G (LTE) HANDOVERS BY-ANKUR TOMAR . 2. HANDOVER • The process of transferring an ongoing call or data session from one channel to another in a cellular network. or When customer with mobile moves from one cell coverage area to other cell coverage area in dedicated (on call) mode without call drop is called Handover.
What are the different types of handover decisions available?
There are two type of handover approach available. • Network Controlled: In this case network makes handover decisions. • Mobile Evaluated: The UE will make handover decisions and inform network about it. But still network takes the final decision based on radio resource available in target cell. handover decisions type
