Multiple subscription resource access control

An apparatus, comprising:

• a signal processing resource;
• a first subscriber identity module (SIM) interface communicatively coupled to the signal processing resource, wherein the first SIM interface is configured to receive a first SIM associated with a first subscription;
• a second SIM interface communicatively coupled to the signal processing resource, wherein the second SIM interface is configured to receive a second SIM associated with a second subscription;
• and
• a controller communicatively coupled to the signal processing resource, wherein the controller is configured to:
• receive a first set of requests to access the signal processing resource during a first time period, wherein at least one of the first set of requests is related to the first subscription and at least one of the first set of requests is related to the second subscription;
• grant access to the signal processing resource to the first subscription during the first time period and deny access to the signal processing resource to the second subscription during the first time period;
• receive a second set of requests to access the signal processing resource during a second time period, wherein at least one of the second set of requests is related to the first subscription and at least one of the second set of requests is related to the second subscription;
• determine, based on a remedial action policy and based on historical information related to subscription access to the signal processing resource, whether to grant access to the signal processing resource to the second subscription during the second time period and to deny access to the signal processing resource to the first subscription during the second time period;
• and
• when access to the signal processing resource is granted to the second subscription during the second time period, use hysteresis to determine whether to grant access to the signal processing resource to the first subscription during a third time period after the second time period in order to preserve paging performance of the first subscription.

An apparatus, comprising:

• means for receiving a first subscriber identity module (SIM) that is associated with a first subscription;
• means for receiving a second SIM that is associated with a second subscription;
• means for receiving a first set of requests to access a signal processing resource during a first time period, wherein at least one of the first set of requests is related to the first subscription and at least one of the first set of requests is related to the second subscription;
• means for granting access to the signal processing resource to the first subscription during the first time period and denying access to the signal processing resource to the second subscription during the first time period;
• means for receiving a second set of requests to access the signal processing resource during a second time period, wherein at least one of the second set of requests is related to the first subscription and at least one of the second set of requests is related to the second subscription;
• means for determining, based on a remedial action policy and based on historical information related to subscription access to the signal processing resource, whether to grant access to the signal processing resource to the second subscription during the second time period and to deny access to the signal processing resource to the first subscription during the second time period;
• and
• means for determining, using hysteresis, whether to grant access to the signal processing resource to the first subscription during a third time period that is after the second time period in order to preserve paging performance of the first subscription when access to the signal processing resource is granted to the second subscription during the second time period.

A computer readable tangible medium comprising instructions that, when executed by a processor, cause the processor to:

• receive a first set of requests to access a signal processing resource of a device during a first time period, wherein the device includes a first subscriber identity module (SIM) associated with a first subscription and a second SIM associated with a second subscription, wherein at least one of the first set of requests is related to the first subscription and at least one of the first set of requests is related to the second subscription;
• grant access to the signal processing resource to the first subscription during the first time period and deny access to the signal processing resource to the second subscription during the first time period;
• receive a second set of requests to access the signal processing resource of the device during a second time period, wherein at least one of the second set of requests is related to the first subscription and at least one of the second set of requests is related to the second subscription;
• determine, based on a remedial action policy and based on historical information related to subscription access to the signal processing resource, whether to grant access to the signal processing resource to the second subscription during the second time period and to deny access to the signal processing resource to the first subscription during the second time period;
• and
• when access to the signal processing resource is granted to the second subscription during the second time period, use hysteresis to determine whether to grant access to the signal processing resource to the first subscription during a third time period after the second time period in order to preserve paging performance of the first subscription
