Aditi Singh, Neeta Nathani . Identification of Suitable Conditions for Handoff in Real Time Mobile Network Technologies. Communications on Applied Electronics. 6, 7 ( Feb 2017), 30-40. DOI=10.5120/cae2017652511
Handoff is an essential process of cellular communications. In most cases, handoff that occurs to avoid sudden termination of the call in between the ongoing conversation is preferred instead of new call origination. Therefore, while managing handoff requests, prioritizing handoff to avoid such abrupt terminations of the ongoing calls over origination of new calls is done which is termed as handoff prioritization. Prioritizing handoff reduces handoff failure and therefore is essential to improve system performance. Also, a handoff algorithm which uses fixed parameters only or the one which tries to reduce the number of handoffs in heavy traffic situations results in poor performance. Again in such situations, prioritizing handoff helps in improving the performance of the system. But there are still some conditions when simply prioritization of handoff is not helpful. This paper describes such situations and identifies those different conditions which are responsible for a fruitful handoff process by comparing receiver level and receiver quality in different mobile networks like UMTS and GSM.
