Abstract
Method and apparatus for a user equipment (UE) operating in a serving cell is disclosed. The UE, in a first RRC_CONNECTED state, transmits an interest indication for a broadcast or a multicast service to a first serving cell. The interest indication includes at least some information associated with a broadcast or a multicast service. Upon entering a second RRC_CONNECTED state from an RRC_INACTIVE state, the UE may or may not send an interest indication to a second serving cell, taking into account the differences between the first and second serving cell, whether the second serving cell requested transmission of an interest indication, or whether the content of the second interest indication would be the same as the content of the first interest indication. A network node may retain UE context and other UE-related information after the UE has left an RRC_CONNECTED state, forward the information to another network node, and/or process the information when the UE re-enters the RRC_CONNECTED state.
