A method includes setting, using at least one processor of an electronic device that includes multiple subscriber identity module (SIM) cards, a maximum Network Address Translation (NAT) interval to be a maximum value among NAT keep-alive intervals associated with the multiple SIM cards. The method also includes triggering, using the at least one processor, a partial call setup from a first SIM card of the multiple SIM cards to a second SIM card of the multiple SIM cards. The method further includes determining, using the at least one processor, whether the electronic device receives the partial call setup. In addition, the method includes, in response to determining that the electronic device receives the partial call setup, setting, using the at least one processor, the NAT keep-alive interval for each of the multiple SIM cards to be equal to the maximum NAT interval.

A method of operating user equipment (UE) for detecting network capability. The method comprises identifying a preferred mode for a voice over long-term evolution (VoLTE) call handover operation from an LTE network to a non-LTE network in a first communication network. The preferred mode is associated with the first communication network. The method further comprises initiating a VoLTE call in a second communication network different than the first communication network, determining whether the second communication network is capable of supporting the preferred mode associated with the first communication network, and one of changing and maintaining the preferred mode based on a result of the determination.

In the receiving side MAC layer timestamping approach, the MPDU structure is changed by adding an extra timestamping field. When a MPDU packet is generated, a captured receiving timestamp is written into the MPDU's timestamp field. The MPDU packet is then forwarded from the PHY to the MAC layer of the wireless sensor node. In the MAC layer, the receiving timestamp is further processed and inserted into a corresponding field of the time synchronization message, which is in turn transmitted to a Time Synchronization module. In the sending side MAC layer timestamping approach, the sending timestamp is captured immediately before the time synchronization message is written into TxFIFO.
