1. A method for optimizing communication cost, the method comprising:
- communicating over a wireless network and a cellular network, wherein a cellular network cost to communicate data is greater than a wireless network cost;
applying a policy containing one or more rules to determine whether to send via the cellular or wireless network the data to the mobile device, each rule being a function of cost, availability, one or more messaging attributes of data, channels or system environment; and
sending the data over the wireless network data if the wireless network is available and otherwise sending the data using the cellular network according to the policy.

2. A method for optimizing communication cost over a wireless area network (WAN) and a cellular network, the method comprising:
-
communicating over the WAN as the first wireless network and the cellular network as the second wireless network, wherein a first wireless network cost to communicate data is greater than a second wireless network cost; applying a policy containing one or more rules to determine whether to send via the first or second wireless network the data to the mobile device, each rule being a function of cost, availability, one or more messaging attributes of data, channels or system environment; and sending the data over the second wireless network data if the second wireless network is available and otherwise sending the data using the first wireless network according to the policy. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A system comprising
a server; -
a plurality of wireless networks coupled to the server; and one or more mobile devices coupled to the wireless networks with intermittent access to the wireless networks, the plurality of wireless networks providing data communication between client and server applications over multiple intermittent connections, wherein the connection is selected based on a least cost, wherein the mobile devices communicate over a wireless area network (WAN) as the first wireless network and the cellular network as the second wireless network, wherein a first wireless network cost to communicate data is greater than a second wireless network cost;
wherein the devices apply a policy containing one or more rules to determine whether to send via the first or second wireless network the data to the mobile device, each rule being a function of cost, availability, one or more messaging attributes of data, channels or system environment; and
the devices communicating data over the second wireless network data if the second wireless network is available and otherwise sending the data using the first wireless network according to the policy. - View Dependent Claims (19, 20)
