Abstract: The present invention provides methods for improving performance and reducing power consumption in a dual subscriber identification module (SIM) dual standby (DSDS) device. According to one example embodiment, the DSDS device enhances the usage of a single RF resource to be shared between a first SIM and a second SIM of the DSDS device based on one or more entry and exit conditions. The DSDS device allows the first SIM to use the RF resource for a data session while it restricts the second SIM from performing neighbor cell measurements when entry conditions are met. By restricting the neighbour cell measurement operations on the second SIM, the DSDS device enables the first SIM to use the RF resource for an extended time thereby improving data rates in the DSDS device. Further, the DSDS device allows the second SIM to perform neighbor cell measurements when the exit conditions are met.

Abstract: The various embodiments of the present invention disclose a system and method for Multimedia Broadcast Multicast Service (MBMS) counting operation is described herein. A method for multimedia broadcast multicast service (MBMS) counting operation is disclosed. In an embodiment of the present application, the method comprises of receiving, by an user equipment (UE), an MBMS counting request from a wireless communication network; sending, by the UE, an MBMS counting response on a dedicated path to the network, if the UE is in connected mode; and triggering, by the UE, a random access channel (RACH) procedure for sending the MBMS counting response, if the UE is in idle mode.

Abstract: Example embodiments herein provide methods and Dual SIM Dual Standby (DSDS) devices including a first Subscriber Identity Module (SIM) and a second SIM for managing data communication. The methods include establishing, by the DSDS device, a Radio Resource Control (RRC) connection over the first SIM and performing data communication with a network entity. Further, the methods include detecting, by the DSDS device, an activity upcoming over the second SIM. Further, the methods include transmitting, by the DSDS device, a connection suspend indication to the network entity to suspend the data communication over the first SIM, wherein the connection suspend indication is transmitted on one of a Layer-1 control signaling channel, a Layer-2 control signaling channel, and a Layer-3 control signaling channel.

Abstract: A method for providing IDLE mode multimedia broadcast multicast service (MBMS) continuity in a telecommunication network is provided. The method includes providing an MBMS of interest for a user equipment (UE) from a first cell in the telecommunication network, using an MBMS gateway, performing a cell re-selection measurement of at least a second cell using the UE, the second cell being a neighboring cell to the first cell, wherein the cell re-selection measurement comprises determining a configuration of the second cell to facilitate an MBMS and determining a signal strength matching a predetermined strength value, and selecting one of the first cell and the second cell using the UE, which is configured to facilitate the MBMS and has a signal strength value at least equal to the predetermined strength value and greater than the other cell.
