Dynamic Resource Adjustment for Establishing and Maintaining a Call of Interest

Abstract

Methods and servers are disclosed for dynamically adjusting mobile communication device resources for maintaining call on the mobile communication device subject to a lawful intercept. Methods may include a server transmitting to the mobile communication device an activation input for activating a call extender daemon that cannot be deactivated. A resource status indication message may be received from the mobile communication device. The resource status indication message may include a state of an onboard resource of the mobile communication device. A resource adjustment input may be transmitted from the server to the mobile communication device. The resource adjustment input may cause the call extender daemon to adjust an operating state of the onboard resource of the mobile communication device based on the activation input to increase a likelihood of maintaining an active call on the mobile communication device and without alerting a user of the mobile communication device.
