Patent number: 9693337Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a request to receive a Multimedia Broadcast Multicast Service (MBMS) service associated with a service area identity (SAI) and a second frequency. The apparatus performs inter-frequency cell reselection from a first cell transmitting at a first frequency to a second cell transmitting at the second frequency, the second cell being an inter-frequency neighbor cell to the first cell. The apparatus receives system information from the second cell. The apparatus determines that the second cell transmitting at the second frequency is unassociated with the SAI based on the received system information. The apparatus blacklists the SAI on the second frequency in a blacklist for at least a period of time upon determining that the second cell is unassociated with the SAI.Type: GrantFiled: September 2, 2014Date of Patent: June 27, 2017Assignee: QUALCOMM IncorporatedInventors: Sivaramakrishna Veerepalli, Jack Shyh-Hurng Shauh, Kuo-Chun Lee, Vaibhav Singhal, Utpal Barman, Daniel Amerga, Muralidharan Murugan, Jun Wang, Ralph Gholmieh
