Patent number: 10432416Abstract: A method for performing evolved multimedia broadcast and multicast service (eMBMS) counting efficiently in wireless systems is provided. The method includes receiving by a radio link control (RLC) layer of a User Equipment (UE), a Multicast Control Channel (MCCH) packet containing an MBMS counting request from a network. The RLC layer then transfers the MCCH packet to a Radio Resource Control (RRC) layer of the UE. The RRC layer processes the MBMS counting request and generating an MBMS counting response by and transmits an indication for successful reception of the MBMS counting request to the RLC layer. The RLC layer verifies if a subsequent MCCH modification boundary indication is received in a selected MCCH modification period and discards one or more subsequent MCCH packets received in a selected MCCH modification period if the MCCH modification boundary indication is not received from a physical layer.Type: GrantFiled: August 12, 2015Date of Patent: October 1, 2019Assignee: Samsung Electronics Co., LtdInventors: Rohan Raj, Vinay Kumar Shrivastava
