Traffic steering between different wireless networks

A traffic-steering device, comprising:

• a first network policy manager to obtain, from a first wireless network characterized by a first radio access technology (RAT), a first set of wireless network policies, wherein the first set of wireless network policies characterizes a first wireless channel provided to a client device by the first wireless network;
• a second network policy manager to obtain, from a second wireless network characterized by a second RAT different from the first RAT, a second set of wireless network policies, wherein the second set of wireless network policies characterizes a second wireless channel provided to the client device by the second wireless network;
• and
• a policy aggregator to generate a set of aggregated policies by aggregating the first set of wireless network policies relating to the first RAT and the second set of wireless network policies relating to the second RAT, based on one or more aggregation criteria, the aggregating comprising:
• identifying a first policy in the first set of wireless network policies;
• identifying a second policy in the second set of wireless network policies;
• and
• generating a third policy based on the first policy, the second policy, and the one or more aggregation criteria, wherein the set of aggregated policies comprises the third policy in place of the first policy and the second policy;
• wherein the traffic-steering device provides, to the client device, the set of aggregated policies, wherein the set of aggregated policies directs the client device to steer traffic to the first and second wireless networks.

A non-transitory computer readable medium storing one or more programs, the one or more programs including instructions, which, when executed by one or more processors of a traffic-steering device, cause the traffic-steering device to:

• obtain, from a first wireless network characterized by a first radio access technology (RAT), a first set of wireless network policies, wherein the first set of wireless network policies characterizes a first wireless channel provided to a client device by the first wireless network;
• obtain, from a second wireless network characterized by a second RAT different from the first RAT, a second set of wireless network policies, wherein the second set of wireless network policies characterizes a second wireless channel provided to the client device by the second wireless network, the obtaining comprising:
• determining an inability to obtain at least one wireless network policy, of the second set of wireless network policies, from a network device associated with the second wireless channel, and in response:
• querying the client device for the at least one wireless network policy;
• and
• receiving, over the first wireless channel from the client device, the at least one wireless network policy;
• generate a set of aggregated policies by aggregating the first set of wireless network policies and the second set of wireless network policies based on one or more aggregation criteria;
• and
• provide, to the client device, the set of aggregated policies, wherein the set of aggregated policies directs the client device to steer traffic to the first and second wireless networks.
