Idle mode operations in multi-subscriber identity module (SIM) mobile communication devices during data communications

摘要

Various embodiments include methods implemented on a mobile communication device for sharing network information among subscriptions when a first subscription is in a data communication session 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.

主权项

1. A method for performing idle mode operations on a mobile communication device when a first subscription is in data communication with a base station and a second subscription is in an idle mode, comprising:
determining, by a processor of the mobile communication device, whether the first subscription and the second subscription share a network operator and are camped on a same base station; receiving, by the processor through a radio frequency (RF resource) of the mobile communication device, network information from the base station using the first subscription; storing, by the processor, the network information in a shared memory of the mobile communication device in response to determining that the first subscription and the second subscription share a network operator and are camped on the same base station; and performing idle mode operations for the second subscription using the network information stored, by the processor, in the shared memory.
