Smart call forwarding and conditional signal monitoring in duos mobile

In this approach we infer the influence of a smart call forwarding service on the call connection process in modern cellular communication networks in mobiles. We analyze in detail only the case when the called user and call receiver signals strengths are low. It is proved that smart call forwarding not only increases usage of services and the percent of successful calls and prevents call drops and the call dismission. On the simple example, we showed that this call loss increase is greater in the case of local (internal) and incoming calls, but smaller in the case of outgoing calls. The reason for this conditional behavior is within the role of call forwarding operates within the case of internal and incoming signal. In this article different call forwarding techniques in LTE network are discussed. Some of these techniques have a few drawbacks such as the performance of the call forwarding mechanism depends on the channel quality and speed of the mobile node, the smart call forwarding optimizing algorithms tend to increase the switchover rate and the switchover prediction techniques cannot predict the switchover if the signal strengths are low. The survey also indicates the promising factors of the switchover mechanisms in LTE as compared to another cellular strength also this approach discusses about conditional smart call forwarding techniques affairs smart call forwarding function decreases the impact of restricted range of users on the limitation of offered signal strength, scrutiny to the case of internal and incoming signal strength without smart call forwarding. This statement is illustrated by comparison on different phone states when Idle, ringing and outgoing calls. After smart call forwarding function, and with this function when considering, separately, internal, incoming, and outgoing calls after the automatic smart call forwarding with the help of other subscriber identity number which is present in the current mobile hand set
