Abstract: A method of providing seamless reception of multimedia broadcast multicast services (MBMS) in a user equipment (UE) having multiple radio frequency (RF) terminals is provided. The method includes receiving MBMS from a primary cell (P-Cell) through a first RF terminal in the UE, receiving a command through the first RF terminal while receiving the MBMS configuring the MBMS on a second RF terminal and receiving the MBMS from a non-primary cell wherein the non-primary cell includes at least one of a secondary cell and a non-serving cell.

Abstract: The various embodiments of the present invention disclose a system and method for Multimedia Broadcast Multicast Service (MBMS) counting operation is described herein. A method for multimedia broadcast multicast service (MBMS) counting operation is disclosed. In an embodiment of the present application, the method comprises of receiving, by an user equipment (UE), an MBMS counting request from a wireless communication network; sending, by the UE, an MBMS counting response on a dedicated path to the network, if the UE is in connected mode; and triggering, by the UE, a random access channel (RACH) procedure for sending the MBMS counting response, if the UE is in idle mode.
