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.

2. The apparatus of claim 1, the pPDP comprising:

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.

3. The apparatus of claim 2, 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).

4. 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.

5. A method for providing for private and public packet data service internet access 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, 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 a packet data service with an IP service absent authentication and absent accounting.

6. The method of claim 5, 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.

7. 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 connected to an intranet and the Internet enabling said mobile station access to the Internet via a private mobile network, 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).

8. The apparatus of claim 7, said private BSC further comprising a radio packet connection disposed between said BAN and said gateway.

9. The apparatus of claim 8, said apparatus further comprising a hub switch disposed between said private BSC and said gateway.

10. The apparatus of claim 7, said private BSC further comprises a BMP discerning whether a number dialed by said mobile station needs the attention of said public BSC.

11. The apparatus of claim 7, said private BSC further comprises a BMP discerning whether a number dialed by said mobile station requires Internet services or not.

12. The apparatus of claim 7, when said public BSC is not accessed during a call from a mobile station, the call is absent authentication and accounting.
