摘要： Embodiments herein provide a method for handling communication with a wireless network by a user equipment (UE). The method includes determining that a data inactivity timer has expired during a PS/CS call recovery procedure with a network. The method identifies whether data inactivity that caused the data inactivity timer to expire is due to a radio link failure with the network. A radio link is recovered through the recovery procedure tor resuming the PS/CS call with the network, in response to identifying that the data inactivity was due to the radio link failure.

摘要： A method and user equipment are provided. The method includes initiating a circuit-switched (CS) connection establishment procedure by transmitting a connection management (CM) service request message to a core network (CN). Mobility management (MM) connection establishment is aborted in response to failing to receive a CM service acceptance message within a time period. In response to subsequently receiving a CM service acceptance message after aborting the MM connection establishment, a circuit-switched (CS) signaling connection release action is performed.

摘要： A method for sharing a radio frequency (RF) resource among multi-subscriber identification module (SIM) stacks in a multi-SIM device, includes: receiving two paging requests from the multi-SIM stacks for performing communication with a network entity via the RF resource; transmitting the two paging received requests to the network entity via the RF resource; detecting a page sharing conflict between the two paging requests of the multi-SIM stacks; determining, based on the detection of the page sharing conflict, a connection status of a connection between each stack of the multi-SIM stacks and the network entity. The connection status indicates a communication medium via which each stack of the multi-SIM stacks is connected with the network entity. The method includes prioritizing, based on the determined connection status, a grant of the RF resource to a stack of the multi-SIM stacks whose connection status indicates a cellular connection as the communication medium.

摘要： A method performed by a user equipment (UE) for establishing a call in a wireless communication network, the method includes determining a first call control (CC) state of the UE after a recovery procedure for a call establishment is performed, sending a CC status enquiry message to a first base station connected to a first network, determining a second CC state of the first base station from a CC status message received from the first base station in response to the CC status enquiry message, and establishing the call by updating the first CC state based on the determined second CC state.

摘要： A method performed by a mobile device for selectively allowing radio-frequency (RF) resource sharing between a plurality of subscriptions associated with a plurality of subscriber identity modules (SIMs) in the mobile device, the method includes transferring access to an RF resource from a first subscription among the plurality of subscriptions to a second subscription among the plurality of subscriptions during an ongoing service through the first subscription based on occurrence of a condition, evaluating one or more network parameters pertaining to communication through the first subscription, and causing the first subscription and the second subscription to share access to the RF resource for a first defined time period based on the evaluating such that message communication through the second subscription is enabled without disconnecting the first subscription from the ongoing service.
