operating the user equipment in a connected mode of the user equipment with respect to the second public land mobile network, wherein in the connected mode with respect to the second public land mobile network, transmission of data from the second public land mobile network to the user equipment is prevented by the second public land mobile network during the paging occasion time interval of the discontinuous reception scheme corresponding to the first public land mobile network based on information regarding the paging occasion time interval with respect to the first public land mobile network transmitted to the second public land mobile network by the user equipment, wherein transmitting the information regarding the paging occasion time interval is performed during operating the user equipment, with respect to the second public land mobile network, in the connected mode of the user equipment.

2. The method according to claim 1 , wherein transmission of data from the second public land mobile network to the user equipment is further prevented during at least one of the group consisting of: a first time interval preceding the paging occasion time interval or a second time interval following the paging occasion time interval.

3. The method according to claim 1 , wherein transmission of data from the second public land mobile network to the user equipment is prevented by the second public and mobile network during the paging occasion time interval of the discontinuous reception scheme corresponding to the first public and mobile network further based on offset information that indicates an absolute time offset between a radio frame in the first public land mobile network and a radio frame in the second public land mobile network.

4. The method according to claim 1 , wherein the information regarding the paging occasion time interval is transmitted using a Radio Resource Control (RRC) message or using a RRC connection request complete message.

5. A Dual Subscriber Identity Module (SIM) dual standby (DSDS) user equipment for use with a first public land mobile network and a second public land mobile network, wherein the first public land mobile network and the second public land mobile network are registered public land mobile networks relative to the user equipment, the user equipment comprising a processor, the processor being configured for:

operating the user equipment according to a discontinuous reception scheme in an idle mode of the user equipment with respect to the first public land mobile network, wherein, in the discontinuous reception scheme, a paging occasion time interval is defined based on a time interval corresponding to a discontinuous reception cycle length and a paging time within the time interval such that, in the discontinuous reception scheme, the user equipment only monitors a paging channel during the paging occasion time interval with respect to the first public land mobile network; and

operating the user equipment in a connected mode of the user equipment with respect to the second public land mobile network, wherein in the connected mode with respect to the second public land mobile network, transmission of data from the second public land mobile network to the user equipment is prevented by the second public land mobile network during the paging occasion time interval of the discontinuous reception scheme corresponding to the first public land mobile network based on information regarding the paging occasion time interval with respect to the first public land mobile network transmitted to the second public land mobile network by the user equipment, wherein transmitting the information regarding the paging occasion time interval is performed during operating the user equipment, with respect to the second public land mobile network, in the connected mode of the user equipment.

6. The DSDS user equipment according to claim 5 , wherein transmission of data from the second public land mobile network to the user equipment is further prevented during at least one of the group consisting of: a first time interval preceding the paging occasion time interval and a second time interval following the paging occasion time interval.

7. The DSDS user equipment according to claim 5 , wherein transmission of data from the second public land mobile network to the user equipment is prevented by the second public land mobile network during the paging occasion time interval of the discontinuous reception scheme corresponding to the first public land mobile network further based on offset information that indicates an absolute time offset between a radio frame in the first public land mobile network and a radio frame in the second public land mobile network.

8. The DSDS user equipment according to claim 5 , wherein the processor is configured for transmitting the information regarding the paging occasion time interval using a Radio Resource Control (RRC) message or using a RRC connection request complete message.

9. A non-transitory processor-readable medium having processor-executable instructions stored thereon for using a user equipment with a first public land mobile network and a second public land mobile network, wherein the user equipment is a Dual Subscriber Identity Module (SIM) dual standby (DSDS) user equipment, wherein the first public land mobile network and the second public land mobile network are registered public land mobile networks relative to the user equipment, the processor-executable instructions, when executed, facilitating performance of the following:

operating the user equipment according to a discontinuous reception scheme in an idle mode of the user equipment with respect to the first public land mobile network, wherein, in the discontinuous reception scheme, a paging occasion time interval is defined based on a time interval corresponding to a discontinuous reception cycle length and a paging time within the time interval such that, in the discontinuous reception scheme, the user equipment only monitors a paging channel during the paging occasion time interval with respect to the first public land mobile network; and

operating the user equipment in a connected mode of the user equipment with respect to the second public land mobile network, wherein in the connected mode with respect to the second public land mobile network, transmission of data from the second public land mobile network to the user equipment is prevented by the second public land mobile network during the paging occasion time interval of the discontinuous reception scheme corresponding to the first public land mobile network based on information regarding the paging occasion time interval with respect to the first public land mobile network transmitted to the second public land mobile network by the user equipment, wherein transmitting the information regarding the paging occasion time interval is performed during operating the user equipment, with respect to the second public land mobile network in the connected mode of the user equipment.

10. The non-transitory processor-readable medium according to claim 9 , wherein transmission of data from the second public land mobile network to the user equipment is prevented by the second public land mobile network during the paging occasion time interval of the discontinuous reception scheme corresponding to the first public land mobile network further based on offset information that indicates an absolute time offset between a radio frame in the first public land mobile network and a radio frame in the second public land mobile network.
