1. A method for obtaining cellular network load information, the method comprising: receiving, by a processor of a cellular endpoint device from a policy server of a cellular network, a decryption key for decrypting the cellular network load information and a policy of the cellular network that indicates how the cellular endpoint device is permitted to respond to the cellular network load information, wherein said cellular endpoint device is a phone; receiving, by the processor, the cellular network load information, wherein the cellular network load information comprises a remaining available capacity of a portion of the cellular network, wherein the cellular network load information is received via a broadcast message from the cellular network, wherein the cellular network load information is encrypted, wherein the policy is received prior to the receiving the cellular network load information; decrypting, by the processor, the cellular network load information the decryption key that was received from the policy server; and performing, by the processor, a task responsive to the cellular network load information that is decrypted, wherein the task is performed based on the policy of the cellular network that indicates how the cellular endpoint device is permitted to respond to the cellular network load information, wherein the task comprises switching the cellular endpoint device between a usage of the cellular network and a usage of a non-cellular network.
