Abstract
A method for optimizing cell selection in a Dual Subscriber Identification Module (SIM) Dual Standby (DSDS) device is provided. The method includes selecting at least one candidate neighbor cell for a first SIM from a mapping table of the DSDS device, the at least one selected candidate neighbor cell corresponding to a cell currently serving a second SIM, wherein the first SIM is out of service and the second SIM is in service, and camping the first SIM onto the at least one selected candidate neighbor cell.
Claims17
A method for optimizing cell selection in a dual subscriber identification module (SIM) dual standby (DSDS) device, the method comprising:
- selecting at least one candidate neighbor cell corresponding to a serving cell currently serving a second SIM among a plurality of candidate neighbor cells of a first SIM from a mapping table of the DSDS device, the mapping table maps each of the plurality of candidate neighbor cells of the first SIM to each of a plurality of serving cells of the second SIM, wherein the first SIM is out of service and the second SIM is in service by the serving cell among the plurality of serving cells of the second SIM;
- and
- camping the first SIM onto the at least one selected candidate neighbor cell, while the DSDS device performs a communication activity with the serving cell currently serving the second SIM and wherein the at least one selected candidate neighbor cell is adjacent to the serving cell currently serving the second SIM.
A method for optimizing cell selection in a dual subscriber identification module (SIM) dual standby (DSDS) device, the method comprising:
- selecting at least one candidate neighbor cell corresponding to a serving cell currently serving a second SIM among a plurality of candidate neighbor cells of a first SIM from a mapping table of the DSDS device, the mapping table maps each of the plurality of candidate neighbor cells of the first SIM to each of a plurality of serving cells of the second SIM during a gap allocated to the second SIM, wherein the first SIM is out of service and the second SIM is in service by the serving cell among the plurality of serving cells of the second SIM;
- and
- camping the first SIM onto the at least one selected candidate neighbor cell, while the DSDS device performs a communication activity with the serving cell currently serving the second SIM, wherein the at least one selected candidate neighbor cell is adjacent to the serving cell currently serving the second SIM.
A dual SIM dual standby (DSDS) device for optimizing cell selection, the DSDS device comprising a controller unit configured to:
- select at least one candidate neighbor cell corresponding to a serving cell currently serving a second SIM among a plurality of candidate neighbor cells of a first SIM from a mapping table of the DSDS device, the mapping table maps each of the plurality of candidate neighbor cells of the first SIM to each of a plurality of serving cells of the second SIM, wherein the first SIM is out of service and the second SIM is in service by the serving cell among the plurality of serving cells of the second SIM;
- and
- camp the first SIM onto the at least one selected candidate neighbor cell, while the DSDS device performs a communication activity with the serving cell currently serving the second SIM, wherein the at least one selected candidate neighbor cell is adjacent to the serving cell currently serving the second SIM.
