Ensuring the best quality of smart multimedia services becomes an essential goal for modern enterprises so there is always a need for effective IP mobility smart management schemes in order to fulfill the following two main functions: (I) interconnecting the moving terminals around the extended indoor smart services. In addition, (II) providing session continuity for instant data transfer in real-time and multimedia applications with negligible latency, efficient bandwidth utilization, and improved reliability. In this context, it found out that the Generalized Multi-Protocol Label Switching (GMPLS) over LTE-A network that offers many advanced services for large numbers of users with higher bandwidths, better spectrum efficiency, and lower latency. In GMPLS, there is an elimination of the routing searches and choice of routing protocols on every core LTE-A router also it provides the architecture simplicity and increases the scalability. A comparative assessment of three types of IPv6 mobility management schemes over the LTE-A provided by using various types of multimedia. By using OPNET Simulator 17.5, In accordance with these schemes, it was proven that the IPv6-GMPLS scheme is the best choice for the system's operation, in comparison to the IPv6-MPLS and Mobile IPv6 for all multimedia offerings and on the overall network performance.

Handover is one of the essential components in the mobility management of wireless systems. It allows the client equipment (UE) to connect between LTE-A networks. The variables that can influence this handover performance are the kind of interfaces in which the handover exists, either X2 or S1 interface, the mobility of the UE and the QCI (Quality of Service Class Identifiers). S1 interface associates the eNodeB to the EPC. It divided into double interfaces, one for the user plane and the other for the control plane. The mobility within LTE-A/SAE as well as mobility to other systems using both 3GPP and non-3GPP technologies. X2 is a new kind of interfaces introduced by the LTE-A Radio Access Network. Neighboring eNodeBs are linked in a peerto-peer fashion to perform handover and provide a means for the rapid coordination of radio resources. This research looks at the handover parameters (e.g. EPS bearer bit loss, BLER, throughput, SNR, LTE-A delay) on the mobile user and eNodeBs. Performance of three different applications measured, namely, Video data streaming, Voice traffic and HTTP web browser running on a mobile user were evaluated with a background traffic. This case study proposes the two types of handover X2 and S1 parameters to achieve a maximum possible quality of multimedia streaming services. Furthermore, discuss the effectiveness of using X2 handover and S1 handover on the overall network performance. Using OPNET Simulator 17.5, it concluded that X2 handover is preferred to operate compared with the S1 handover, also is a very good choice for all multimedia services and the overall network performance.

Power optimization is a critical challenge in multimedia services over cellular communication systems. Long Term Evolution-Advanced (LTE-A) has been developed for higher bandwidth access for accommodating today's heavy data applications to provide better performance. Idle mode permits cellular stations to manipulate power and sources with the aid of limiting its activity for discrete periods and this eliminates the lively requirement for handover and other ordinary operations. Also, provides a periodical method for the cell station for pending downlink traffic directed to the cellular station and as a result gets rid network handover traffic from basically inactive cellular stations. Discontinuous Reception (DRX) has been carried out to decrease the power intake of the consumer device, and transmission of big quantity of data. At data transfer, mobile device and the network phases negotiation occur. During other times, the device turns its receiver off and enters a low power state. Thereby similarly assisting numerous services and big quantities of information transmissions. This study prepossession of a massive quantity of data. Also proposes the two-power optimization modes idle mode and DRX mode parameters to achieve maximum possible power saving with the higher quality of multimedia services. Furthermore, the effectiveness of using DRX short cycles and DRX long cycles on multimedia services and the overall performance. Using OPNET Simulator 17.5, it concluded that DRX mechanism is preferred to operate compared with the Idle mechanism, also resulted that the DRX long cycles are a very good choice for all multimedia services and the overall network performance.
