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.
When handover is triggered in LTE?
This handover is triggered when the UE moves from one MME area to another MME area. 1. As mentioned in the previous section (Intra-MME/ SGW handover), based on the MEASUREMENT REPORT from the UE, the S-eNB decides to handover the UE to another eNodeB (T-eNB).
Why is LTE hard handover?
Hard handover mechanism is adopted to be used in 3GPP Long Term Evolution (3GPP LTE) in order to reduce the complexity of the LTE network architecture. This mechanism comes with degradation in system throughput as well as a higher system delay.
What is a handover procedure?
Effective handover consists of three elements: A period of preparation by out-going personnel; Handover where out-going and in-coming personnel communicate to exchange task-relevant information; and. Cross-checking of information by in-coming personnel as they assume responsibility for the task.
What is 5G handover?
In 5G networks, an intra-system handover is used to transfer a User Equipment (UE), such as a mobile phone, from one Radio Access Network (RAN) to another. A handover may be required for reasons including load balancing, changed radio conditions, or user movement [TS 23.502, Sec. 4.9. 1.1].
What is S1 and X2 handover in LTE?
The X2 procedure is used to handover a UE from a source (H)eNB to a target (H)eNB for which the MME is unchanged. The S1 procedure is used by the source eNB to initiate a handover through the S1-MME interface, see [4].
Why soft handover is not included 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.
Which type of handover is not required in LTE?
Explanation: LTE supports only hard handover. It does not receive data from two frequencies at the same time because switching between different carrier frequencies is very fast so soft handover is not required.
What is the purpose of a handover document?
Definition: Handover Notes are documents created by staff members who are about to leave their positions, either temporarily or permanently, to assist their successor to carry out their duties.
How do you handle handovers?
Hence, there are six steps below that can help to successfully complete a project handover:
- Setting handover objectives.
- Keeping the customer up to date.
- Having short daily meetings.
- Showing project benefits and utility for the upcoming project manager.
- Meeting the stakeholders.
- Being available to ask support.
What is LTE handover event?
Handover Events in LTE Normally LTE UE makes radio measurement in two stages which are idle and connected states. In idle state mode the measurement is used for cell selection and cell re-selection. In connected state mode, the measurement is used for handover and redirection scenarios, of course here we mean only mobility cases.
What is the difference between intra-LTE handover and inter-LTE handover?
Intra-LTE Handover: In this case source and target cells are part of the same LTE network. Inter-LTE Handover: Handover happens towards other LTE nodes. (Inter-MME and Inter-SGW)
What is intra E-UTRAN handover in LTE?
LTE Handovers – Intra E-UTRAN Handover. Posted on 10. 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 seamless handoff between 2g/3g/cdma/LTE?
Seamless handoff between 2G/3G/CDMA/LTE technologies. 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.
