Provided are a channel time allocation method and apparatus adopting the same. The channel time allocation method includes: (a) receiving a request of registering in a network from a device; (b) determining whether the network supplying a service required by the device exists; and (c) if the network supplying the requested service exists, performing a procedure of registering in the network, and if the network supplying the requested service does not exist, generating a new network. Since existing MAC protocols can be used in the channel time allocation method, an optimum service is provided in a network environment in which different kinds of services coexist.

What is claimed is: 1. A channel time allocation method comprising: (a) receiving a request to become a member of a network from a device; (b) determining whether the network supplying a service requested by the device exists; and (c) if the network supplying the requested service exists, allowing the device to become the member of the network, and if the network supplying the requested service does not exist, generating a new network, wherein the new network is generated by obtaining a channel time allocation (CTA). 2. The channel time allocation method of claim 1, wherein the network is a piconet and the new network is a neighbor piconet. 3. The channel time allocation method of claim 2, wherein, in (c), the neighbor piconet is generated by obtaining the CTA from a parent piconet. 4. The channel time allocation method of claim 2, further comprising: (d) setting the device to be a piconet coordinator (PNC) of the neighbor piconet after the neighbor piconet is generated. 5. The channel time allocation method of claim 2, wherein the neighbor piconet uses a medium access control (MAC) protocol different from that used by the parent piconet. 6. The channel time allocation method of claim 1, wherein the service is classified according to characteristics of application data and the device is grouped according to a quality of service (QoS) of the service. 7. The channel time allocation method of claim 6, wherein the application data is classified into one of isochronous data and asynchronous data. 8. The channel time allocation method of claim 1, wherein the new network is a wireless network. 9. The channel time allocation method of claim 1, wherein the generating a new network comprises creating a new network. 10. The channel time allocation method of claim 1, wherein the new network uses a medium access control (MAC) protocol. 11. The channel time allocation method of claim 10, wherein the MAC protocol is one of carrier sense multiple access with collision avoidance and time division multiple access. 12. The channel time allocation method of claim 1, wherein if the new network is generated, the device becomes a network coordinator of the new network. 13. A channel time allocation apparatus comprising: an allocating unit, which receives a request from a device to become a member of a piconet; a piconet generator, which generates a neighbor piconet when a piconet supplying a service requested by the device does not exist; a piconet coordinator (PNC) operator, which sets the device to be a PNC of the neighbor piconet after the neighbor piconet is generated and operate as a PNC; and a medium access control (MAC) operator, which assigns a MAC protocol to the PNC of the neighbor piconet suitable for characteristics of the service, wherein the neighbor piconet is generated by obtaining a channel time allocation (CTA). 14. The channel time allocation apparatus of claim 13, wherein the piconet generator generates the neighbor piconet by obtaining the CTA from a parent piconet. 15. The channel time allocation apparatus of claim 13, wherein the MAC operator assigns a MAC protocol different from that used by the parent piconet. 16. The channel time allocation apparatus of claim 13, wherein the service is classified according to characteristics of application data and the device is grouped according to a quality of service (QoS) of the service. 17. The channel time allocation apparatus of claim 16, wherein the application data is classified into one of isochronous data and asynchronous data. 18. A computer readable medium having recorded thereon a computer readable program for performing the method of channel time allocation, the method comprising: receiving a request to become a member of a network from a device; determining whether the network supplying a service requested by the device exists; and if the network supplying the requested service exists, allowing the device to become the member of the network, and if the network supplying the requested service does not exist, generating a new network, wherein the new network is generated by obtaining a channel time allocation (CTA).
