Problems solved by technology
[0026] In addition to the loss of wireless system efficiency, this behavior may have a rather negative impact on user experience
Especially if data loss is so high that TCP / IP retransmission behavior is triggered causing slow start of TCP / IP connection

The present invention relates to a method of using a user equipment by means of a first public land mobile network and a second public land mobile network, wherein the user equipment is used as a DSDS user equipment (dual SIM dual standby user equipment), wherein the first public land mobile network The mobile network is a registered public land mobile network for the user equipment and wherein the second public land mobile network is also a registered public land mobile network for the user equipment, wherein relative to the first public land mobile network, the The first operating mode of the user equipment corresponds to using a discontinuous reception scheme in the idle mode of the user equipment, wherein in the discontinuous reception scheme of the user equipment, a paging occasion time interval is defined by means of : a time interval, corresponding to a discontinuous reception cycle length, and a paging time in the time interval, so that in the discontinuous reception scheme, the user equipment only needs to be in the paging occasion time interval monitoring a paging channel, wherein with respect to the first public land mobile network, the second mode of operation of the user equipment corresponds to using the discontinuous reception scheme in said idle mode of the user equipment, and with respect to the second public land mobile network, the second operating mode of the user equipment corresponds to the connected mode of the user equipment, wherein, in the second operating mode of the user equipment, the data from the second public land mobile network to the user equipment During transmission, the data transmission is prevented during the paging occasion time interval.
Description
Background technique [0001] The present invention relates to a method of using user equipment by means of a first public land mobile network and a second public land mobile network, wherein the user equipment is used as a DSDS user equipment (dual-SIM dual-standby user equipment). [0002] The invention also relates to a user equipment used by means of a first public land mobile network and by means of a second public land mobile network, wherein the user equipment is used as a DSDS user equipment (dual SIM dual standby user equipment). [0003] In cellular mobile systems like GSM (Global System for Mobile Communications) (but also in cellular public land mobile networks, according to their successor systems like UMTS (Universal Mobile Telecommunications System) or E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) / LTE (Long Term Evolution)), the so-called "PLMN selection" (PLMN = Public Land Mobile Network) is performed by the User Equipment (UE), as defined in [3GPP TS...
