Abstract

An apparatus and method for accessing a private wireless Internet packet data communication system. A private packet data service apparatus includes a plurality of private BTSs positioned in an private packet data service zone and an private BSC for providing a wireless packet data service using a CDMA method. The private BTSs wirelessly communicate with terminals contained in a corresponding service zone. In the case where dialing numbers of calls requested by the private BTSs are not private packet service request signals, the private BSC transmits the calls to a public network BSC. In the case where dialing numbers of calls requested by the private BTSs are private packet service request signals, the private BSC provides the calls with a packet data service for which a non-authentication, a non-accounting, and an IP service are available. The private BSC includes a PDCC (Packet Data Call Controller), a PDTC (Packet Data Traffic Controller), and a PDMA (Packet Data Maintenance & Administration part). The PDCC generates or terminates an RP (Radio Packet) connection needed to perform packet data transmission/reception of a terminal between an AMC and a DCN (Data Core Network), and processes a state conversion concerning a packet call. The PDTC performs data transmission/reception between the AMC and the DCN. The PDMA performs an interface between a BAN and maintenance/administration blocks, checks states of the AMC and an ATM PVC, and checks a link state between the AMC and a DCN.

Claims

1. An apparatus, comprising:

a plurality of private BTSs (Base Transceiver Systems) allocating a wireless resource to a plurality of mobile terminals positioned in an office packet data service area, and performing a radio communication with the terminals; and

a private BSC (Base Station Controller) for providing CDMA service comprising a packet data service when calls requested by the private BTSs correspond to office packet service request signals,

the private BSC comprising;

a BMP hardware board having a software block determining whether a number dialed by one of said plurality of mobile stations is a private or a public call and whether said number is for a telephone or for an internet connection;

an ATP-d (Air Termination Processor board) for controlling radio packet data and signals of the private BSC and processing generation of the radio packet data and signals; and

a pPDP (private Packet Data Processor) connected between the private BSC and a DCN (Data Core network), said pPDP providing said private radio packet service, wherein the pPDP comprises;

a PDCC (Packet Data call Controller) allocating/releasing an IP (Internet Protocol) needed to establish packet data transmission/reception of a terminal between an ATP-d and the DCN, managing generation/termination of a RP (Radio Packet) connection, and processing a state concerning a packet call;

a PDTC (Packet Data Traffic Controller) performing packet data transmission/reception between the ATP-d and the DCN; and

a PDMA (Packet Data Maintenance &

Administration part) for checking an interface with the private BSC and a state of the interface.

2. The apparatus of claim 1, the PDCC comprises:

a signaling daemon processor processing messages related to a data service of a terminal, messages related to a time used in a packet control controller, and messages used for processing data of the terminal in a dormant state;

a packet call controller controlling a state of each packet call, and controlling a state transition of a corresponding terminal upon receiving a predetermined message; and

a packet location register processor managing state conversion information of a terminal by the packet call controller, and transmitting the state conversion information to each module in the form of a functional API (Application Program Interface).

3. The apparatus of claim 1, the PDTC comprises:

a traffic daemon processor transmitting a received data packet to a PMI task, requesting a dormant paging, setting flags related to a program flow control, initializing queues when terminating a dormant state, and thus processing signaling operations related to an AMC (ATP Mac Control, ATP;

Air Termination Processor) and traffic;

a data transmission part managing a list of the queues, and transmitting a message of the queues to the AMC;

a PMI processor receiving LCP/IPCP/IP protocol frames from a terminal, and processing them; and

a network processor for performing an Ethernet packet communication with the DCN.

4. A method for providing for private and public packet data Internet access service and private and public phone services to a mobile station in communication with a private BTS in an Internet communication system, said method comprising the steps of:

allocating/releasing an IP (Internet Protocol) needed to establish packet data transmission/reception of said mobile station between an ATP-d (Air Termination Processor board) and the DCN (Data Core network), managing generation/termination of a RP (Radio Packet) connection, and processing a state conversion concerning a packet call;

performing data transmission/reception between an AMC and the DCN; and

performing an interface between a BAN (BSC ATM Network) and maintenance/administration blocks, checking states of the AMC (ATP Mac Control, ATP;

Air Termination Processor) and an ATM PVC (Asynchronous Transfer Mode Permanent Virtual Circuit), and checking a link state between the AMC and the DCN, when a dialing number of a call requested by the private BTS is not an private packet service request signal, the call information is transmitted to a public network BSC; and

when a dialing number of a call requested by the private BTS is a private packet service request signal, the call receives the public packet data Internet access service absent authentication and absent accounting.

5. The method of claim 4, said Internet communication system comprising:

a plurality of BTSs (Base Transceiver Systems) allocating a wireless resource to terminals positioned in an private packet data service area and performing a radio communication with the mobile station; and

a private BSC (Base Station Controller) providing a packet data service when calls requested by the private BTS corresponds to private packet service request signals, the private BSC comprising

a BMP processing a radio call and determining whether a call placed by said mobile station is a private call or public call by analyzing a phone number received from the mobile station;

an ATP-d (Air Termination Processor board) controlling radio packet data and signals of the private BSC, and processing generation of the radio packet data and signals; and

a pPDP (private Packet Data Processor) connected between the private BSC and a DCN (Data Core network) providing the private radio packet service.

6. The method of claim 4, when a dialing number of a call requested by the private BTS is a private packet service request signal, the call is routed through a gateway in order to connect with the Internet.

7. The method of claim 4, wherein calls to the public Internet from said mobile station absent said authentication and accounting are accomplished without being routed through a public mobile communications network.

8. An apparatus, comprising:

a private BTS;

a mobile station in wireless communication with said private BTS; and

a private BSC connected to said private BTS, said private BSC connected to a gateway, said gateway connected to an intranet and the public Internet, said gateway enabling said mobile station access to the public Internet via a private mobile network absent authentication and absent accounting, said private BSC connected to a public BSC enabling said mobile station to have access to a public mobile network, said private BSC comprising;

a BAN (BSC ATM network); and

an ATP-d (air terminal processor board).

9. The apparatus of claim 8, said private BSC further comprising a radio packet connection disposed between said BAN and said gateway.

10. The apparatus of claim 9, said apparatus further comprising a hub switch disposed between said private BSC and said gateway.

11. The apparatus of claim 8, said private BSC further comprises a BMP discerning whether a number dialed by said mobile station needs the attention of said public BSC.
