1. A method comprising:

  • obtaining, by a processor of a policy server of a cellular network, cellular network load information, wherein the cellular network load information comprises a volume of a bandwidth used for user traffic and for control traffic by the cellular network;

    encrypting, by the processor, the cellular network load information;

    determining, by the processor, a decryption key for decrypting the cellular network load information that is encrypted; and

    sending to an endpoint device, by the processor, the decryption key for decrypting cellular network load information and a policy of the cellular network that indicates how the endpoint device is permitted to respond to the cellular network load information, wherein the endpoint device is a phone, wherein the cellular network load information is sent via a broadcast message from the cellular network, wherein the policy is sent prior to the sending the cellular network load information, wherein the cellular network load information that is decrypted enables the endpoint device to perform a task responsive to the cellular network load information, wherein the task is performed based on the policy, wherein the task comprises switching the endpoint device between a usage of the cellular network and a usage of a non-cellular network.
