Femto nodes provide Local IP Access (LIPA) which allows terminals to communicate with local area networks that the femtocells reside in using cellular air-interfaces (such as cdma2000, UMTS or LTE). Femto nodes also enable Remote IP Access (RIPA) service, which allows the terminals to access the local area network from the Internet as if they were present in the local area networks. Further, to avoid degradation of standby time of the terminals or the capacity of the femto node, or both, apparatus and methods are described herein in which a femto node consolidates received Broadcast/Multicast IP packets from a local area network prior to delivering the packets to terminals over a cellular air-interface. In other aspects, a femto node may deliver the received Broadcast/Multicast IP packets via a cellular one-to-many transmission, either with or without consolidation. |
