Patent ID: 8274956

Claim:
A method operable by a user device of receiving broadcast or multicast traffic, comprising: identifying at least one of a plurality of different wireless sub-networks from which traffic is to be received, wherein the plurality of different wireless sub-networks are associated with a common network, wherein the traffic is communicable between the plurality of different wireless sub-networks, and wherein the user device is operable to receive the traffic from at least two of the plurality of different wireless sub-networks; receiving via a first wireless sub-network of the plurality of different wireless sub-networks, a first traffic type of a plurality of different types of broadcast or multicast traffic; and receiving via a second wireless sub-network of the plurality of different wireless sub-networks, a second traffic type of the plurality of the different types of broadcast or multicast traffic, wherein the first traffic type of the different types of broadcast or multicast traffic comprises user plane traffic, and the second traffic type of the plurality of the different types of broadcast or multicast traffic comprises control plane traffic; wherein a transmission schedule is different for the first traffic type of the different types of broadcast or multicast traffic via the first wireless sub-network than for the second traffic type of the plurality of the different types of broadcast or multicast traffic via the second wireless sub-network, and wherein the first traffic type of the different types of broadcast or multicast traffic is received at a different time than the second traffic type of the plurality of different types of broadcast or multicast traffic; waking from a power save state, at a time interval defined by the transmission schedule associated with the first wireless sub-network, to receive traffic via the first wireless sub-network; and waking from a power save state, at a time interval defined by the transmission schedule associated with the second wireless sub-network, to receive traffic via the second wireless sub-network; wherein the time interval defined by the transmission schedule associated with the second wireless sub-network is different than the time interval defined by the transmission schedule associated with the first wireless sub-network.
