## Abstract

A method for managing wireless device communications including establishing active, persistent, and repetitive communications with a wireless device operating in a coverage area of a local wireless network. In an example, the local wireless network is and overlay to a portion of a macro wireless network. The repetitive communications include placing a call to the wireless device, completing a call connection to the wireless device, sending a message to the wireless device, receiving and processing a response to the message from the wireless device, and persistently repeating a call function of the placing a call, completing a connection, sending a response, and receiving and processing the response until a specified termination event. In an embodiment, the termination event is a power off of the wireless device.

placing a first call to the first wireless device,
receiving and processing a first response from the first wireless device,
initiating a first call clearance, and
repeating a call function of placing a call, receiving and processing a response from the first wireless device, and initiating a call clearance while the first wireless device is powered on and within the boundary.

### Claim 2 (depends on 1)

### Claim 3 (depends on 1)

The method of claim 1, wherein the first call is a voice call and the first response is a human voice return.

### Claim 4 (depends on 1)

The method of claim 1, wherein the first call is a text (SMS) message and the first response is a text message.

### Claim 5 (depends on 1)

The method of claim 1, wherein the first call is a data communication.

### Claim 6 (depends on 5)

The method of claim 5, wherein the data communication is an email and the first response is a voice call.

### Claim 7 (depends on 5)

The method of claim 5, wherein the data communication is an email and the first response is an email.

### Claim 8 (depends on 1)
