## Abstract

A method and apparatus for quickly forming a PAN is describe herein. During operation a device will detect that it has gone from a charging state to a non-charging state (i.e., a battery not being charged). Moving from a charging state to a non-charging state is utilized as a trigger to form or join a PAN. Thus, a PAN can quickly be formed at the beginning of an officer's shift, simply by removing devices from a charger.

## Claims

### Claim 1

A method for a device to form a network, the method comprising the steps of:
detecting that a battery going from a charging state to a non-charging state; and
forming the network with other devices based on the battery going from the charging state to the non-charging state.

### Claim 2 (depends on 1)

The method of claim 1 further comprising the steps of:
detecting a signal strength of the other devices; and
wherein the step of forming the network with the other devices further comprises the step of forming the network with other devices having the signal strength above a predetermined threshold, and also based on the battery going from the charging state to the non-charging state.

### Claim 3 (depends on 2)

The method of claim 2 further comprising the steps of:
determining a battery charger identification (ID); and
wherein the step of forming the network with the other devices further comprises the step of forming the network with other devices having the signal strength above the predetermined threshold, and also based on the battery going from the charging state to the non-charging state, and also based on the battery charger ID.

### Claim 4 (depends on 1)

The method of claim 1 further comprising the steps of:
determining a battery charger identification (ID); and
wherein the step of forming the network with the other devices further comprises the step of forming the network with other devices based on the detection of the battery charger ID and also based on the battery going from the charging state to the non-charging state.

### Claim 5 (depends on 1)

The method of claim 1 further comprising the steps of:
determining a time; and
forming the network with other devices within a predetermined time of the battery going from the charging state to the non-charging state.

### Claim 6 (depends on 1)

The method of claim 1 wherein the network comprises a personal area network (PAN).

### Claim 7 (depends on 1)

The method of claim 1 wherein the step of forming the network comprises the step of pairing/associating with the network.

### Claim 8

An apparatus comprising:
a battery being capable of being charged by a battery charger;
logic circuitry coupled to the battery, the logic circuitry detecting that the battery is going from a charging state to a non-charging state, the logic circuitry forming a network with other devices based on the battery going from the charging state to the non-charging state.

### Claim 9 (depends on 8)

The apparatus of claim 8 further comprising:
a wireless receiver detecting a signal from other devices; and
wherein the logic circuitry forms the network by forming the network with other devices having a signal strength above a predetermined threshold, and also based on the battery going from the charging state to the non-charging state.

### Claim 10 (depends on 9)

The apparatus of claim 9 further comprising:
a charging port receiving a battery charger identification (ID); and
wherein the logic circuitry forms the network by forming the network with other devices having the signal strength above the predetermined threshold, and also based on the battery going from the charging state to the non-charging state, and also based on the battery charger ID.

### Claim 11 (depends on 8)

The apparatus of claim 8 further comprising:
a charging port receiving a battery charger identification (ID); and
wherein the logic circuitry forms the network by forming the network with other devices based on the detection of the battery charger ID and also based on the battery going from the charging state to the non-charging state.

### Claim 12 (depends on 8)

The apparatus of claim 8 wherein the network comprises a personal area network (PAN).

### Claim 13 (depends on 8)

The apparatus of claim 8 wherein forming the network comprises pairing/associating with the network.

### Claim 14 (depends on 8)

The apparatus of claim 8 further comprising:
a timer outputting a time; and
the logic circuitry forms the network by forming the network with other devices within a predetermined time of the battery going from the charging state to the non-charging state.

### Claim 15

A method comprising the steps of:
detecting that a battery going from a charging state to a non-charging state;
determining a period of time that has elapsed after going to the non-charging state;
detecting a signal strength of other devices;
determining a battery charger identification (ID); and
forming a network with other devices based on going from the charging state to the non-charging state, and based on the battery charger ID, and wherein the other devices have a signal strength above a predetermined threshold, and the network formed within the period of time.
