This paper gives an overview on call handover process in cellular communication network. Mobility is key issue in current and future cellular networks such as GSM, UMTS and LTE. The handover process impacts on Quality of Service for network provider. If this process accomplishes inaccurately handover can result in loss of call. Handover is the process in which active call is transferred from one cell to another cell as the subscriber moves all over the coverage area of cellular network. Received signal level, received signal quality etc. parameters play vital role in handover decision process. MS station detects the signal level of current serving BTS along with surrounding BTS. The type of handover occurrence depends on cellular network structure. In this paper we revised the concept of handover process, different handover schemes and types then we briefly illustrate inter BSC handover sequence process.
