## Abstract

A method and apparatus for allocating a management resource of a channel of a node that is included in a wireless personal area network (WPAN) are provided. A resource of a channel performs communication with a specific node using a multi-superframe including a plurality of superframes, limits a position area of a time slot including a channel that is allocated to communication with a specific node to a predetermined superframe of the plurality of superframes, gives a logical connection ID to the time slot, and is allocated by matching the logical connection ID and a management resource that manages the time slot.

## Claims

### Claim 1

A method of allocating a management resource of a channel of a node that is included in a wireless personal area network (WPAN), the method comprising:
performing communication with a specific node using a multi-superframe in which a plurality of superframes are included;
limiting a position area of a time slot comprising a channel that is allocated to communication with the specific node to a predetermined superframe of the plurality of superframes;
giving a logical connection ID to the time slot; and
matching the given logical connection ID and a management resource of the time slot.

### Claim 2 (depends on 1)

The method of claim 1, wherein the limiting of a position area of a time slot comprises focusing a position area of the time slot to one superframe of the plurality of superframes.

### Claim 3 (depends on 1)

The method of claim 1, wherein the limiting of a position area of a time slot comprises distributing a position area of a time slot to at least two superframes of the plurality of superframes.

### Claim 4 (depends on 1)

The method of claim 1, further comprising aligning the limited position area.

### Claim 5 (depends on 4)

The method of claim 4, wherein the aligning of the limited position area is repeatedly performed according to a preset cycle.

### Claim 6

A resource allocation apparatus that allocates a management resource of a channel of a node that is included in a WPAN, the resource allocation apparatus comprising:
a communication module that performs communication with a specific node using a multi-superframe in which a plurality of superframes are included;
a position area designation module that limits a position area of a time slot comprising a channel that is allocated to communication with the specific node to a predetermined superframe of the plurality of superframes;
a connection ID conversion module that gives a logical connection ID to the time slot; and
a connection ID matching module that matches the given logical connection ID and a management resource of the time slot.

### Claim 7 (depends on 6)

The resource allocation apparatus of claim 6, wherein the position area designation module focuses a position area of a time slot to one superframe of the plurality of superframes.

### Claim 8 (depends on 6)

The resource allocation apparatus of claim 6, wherein the position area designation module distributes a position area of a time slot to at least two superframes of the plurality of superframes.

### Claim 9 (depends on 6)

The resource allocation apparatus of claim 6, further comprising an alignment module that aligns the limited position area.

### Claim 10 (depends on 9)

The resource allocation apparatus of claim 9, wherein the alignment module repeatedly aligns the limited position area according to a preset cycle.
