Abstract:
Due to the development of mobile communication technologies, multimedia services for mobile devices or other services have begun to be commercialized. In this paper, we propose a method that minimizes channel switching time by pre-computing the user’s preferred channels in the LTE-Advanced System. The existing composition of the Multimedia Broadcast Multicast Service (MBMS) using the Internet Group Management Protocol (IGMP) transfers data using multicast from the Broadcast Multicast Service Center (BM-SC) to evolved Node B (eNB), and with broadcast from eNB to the User Equipment (UE). Therefore, in the case of channel switching, the IGMP Join report should be transferred to the BM-SC, where it then waits for the user’s content to be retransferred from eNB. However, in the case of our proposed method, the subscriber channel technique of priorities is used to minimize the wait times between channel switching as the UE broadcasts its favorite channels in advance. Our performance is evaluated using mathematical modeling and shows that the delay time can be reduced from approximately 30 to 79% in terms of the channel switching time.
