Abstract
Various embodiments include methods implemented on a mobile communication device for sharing network information among subscriptions when a first subscription is in a voice call and a second subscription is in an idle mode. The methods may include determining whether the first subscription and the second subscription share a network operator and are camped on a same base station. If so, the first subscription may receive network information from the base station and store the network information in a shared memory of the mobile communication device that can be accessed by the second subscription. The second subscription may then perform some idle mode operations using the network information stored in the shared memory.
