Multi-SIM Cooperative Paging to Reduce Resource Switching Power

The patent merges the paging reception functions of multiple SIM cards into a unified resource allocation mechanism. The network device coordinates paging resources across different SIM cards, allowing them to share receiving resources rather than each SIM card requiring dedicated independent resources. This combining approach maintains reliable paging reception for all SIM cards while reducing overall power consumption by eliminating frequent resource switching.

The patent introduces the network device as an intermediary that manages paging resource allocation for multiple SIM cards. Instead of the terminal device internally managing complex resource switching between SIM cards, the network device externally coordinates the paging resources. This mediator approach simplifies the terminal device's resource management complexity while ensuring each SIM card maintains its independent paging reception capability.

The patent implements preliminary action by pre-configuring paging resources for multiple SIM cards through network coordination. The network device allocates and prepares paging resources in advance for different SIM cards, so when paging is needed, the terminal device can quickly access the pre-allocated resources without time-consuming switching. This preliminary resource preparation reduces service switching time while maintaining the ability to serve multiple SIM cards.
