Abstract
Methods, devices, and systems are disclosed for allocating the Radio Frequency (RF) resources of a multi-Subscriber Identification Module (SIM) device among multiple installed SIMS to receive their respective paging signals. In one embodiment, a method comprises generating a paging pattern of the first SIM, detecting a first collision between Radio Frequency (RF) resource allocations to the first SIM and the second SIM for receiving the paging signal, wherein RF resources are not allocated to the first SIM in the collision, and allocating the RF resources to the first SIM or the second SIM based on the generated paging pattern of the first SIM after the first collision.
Claims20
A method of receiving a paging signal by a multi-Subscriber Identification Module (SIM) device including at least a first SIM and a second SIM, the method comprising:
- generating at least two sub-paging patterns of the first SIM based on at least two sequences of paging signals for the first SIM;
- generating a paging pattern of the first SIM by performing OR operation on the at least two sub-paging patterns of the first SIM;
- detecting a first collision between Radio Frequency (RF) resource allocations to the first SIM and the second SIM for receiving the paging signal, wherein RF resources are not allocated to the first SIM in the collision;
- and
- allocating the RF resources to the first SIM or the second SIM based on the generated paging pattern of the first SIM after the first collision.
A multi-Subscriber Identification Module (SIM) device including at least a first SIM and a second SIM, the multi-SIM device comprising:
- a transceiver;
- a memory;
- and
- a processor coupled to the transceiver and the memory,
- wherein the processor is configured to:
- generate at least two sub-paging patterns of the first SIM based on at least two sequences of paging signals for the first SIM;
- generate a paging pattern of the first SIM by performing OR operation on the at least two sub-paging patterns of the first SIM;
- detect a first collision between Radio Frequency (RF) resource allocations to the first SIM and the second SIM for receiving their respective paging signals, wherein the RF resources are not allocated to the first SIM at a time of the first collision;
- and
- allocate the RF resources to the first SIM or the second SIM based on the generated paging pattern of the first SIM after the first collision.
A chip for a multi-Subscriber Identification Module (SIM) device comprising at least a first SIM and a second SIM, the chip configured to:
- generate at least two sub-paging patterns of the first SIM based on at least two sequence of paging signals for the first SIM,
- generate a paging pattern of the first SIM by performing OR operation on the at least two sub-paging patterns of the first SIM,
- detect a first collision between Radio Frequency (RF) resource allocations to the first SIM and the second SIM for receiving their respective paging signals, wherein the RF resources are not allocated to the first SIM at a time of the first collision, and
- allocate the RF resources to the first SIM and the second SIM based on the generated paging pattern of the first SIM after the first collision.
