Inventor: HYUNG JAE U
IPC: H04L12/14
Filed: 2001-12-19
Abstract: PURPOSE: A terminal authenticating and accounting method of a mobile communication packet network is provided to control the number of log-ins attempted for connection to a network with the same log-in account. CONSTITUTION: When a RADIUS(Remote Authentication Dial-In User Service) server receives an access-request message from an NAS(Network Access Server)(S40), the RADIUS server searches a subscriber information table on the basis of subscriber information included in the access-request message and authenticates a mobile terminal which has performed a log-in(S42). If the authentication on the mobile terminal is successful, the RADIUS server searches an accounting information table with the subscriber information to check the number of sessions being used by a corresponding mobile subscriber(S48). It is judged whether the number of sessions exceeds a number of sessions allowed for the mobile subscriber(S50). If the number of sessions does not exceed the number of sessions allowed for the mobile subscriber, the RADIUS server adds authorization information of the mobile subscriber to an access-accept message and transmits it to the NAS(S52).

Title: Method for performing subscriber monitor testing in full electronic exchange
Inventor: KO GWANG SEOP
IPC: H04M3/26
Filed: 2001-12-28
Abstract: PURPOSE: A method for testing subscriber monitoring in a full electronic exchange is provided to deliver a signal tone to a subscriber when an operator attempts a monitoring test for the busy subscriber, so that the subscriber recognizes the monitoring test, thereby preventing illegal wiretapping. CONSTITUTION: An operator inputs a command to perform a monitoring test for a subscriber requesting the test(S201). An LTTM(Line and Trunk Test Management) unit decides whether a number for the subscriber is valid(S202). If invalid, the LTTM outputs an error message to end the test(S211) If valid, the LTTM checks whether the subscriber is registered in a host or an RASM(Remote Access Switching Module)(S203), to decide whether the subscriber and the operator is in a test available state. In the test available state, an AST(Analog Subscriber Test) unit decides whether a line state is an occupied state(S204). If not, the AST outputs an error message to end the test(S212), and if the line state is an occupied state, an ASC(Analog Subscriber Control) unit pages an LSL(Local Switching system Library) to release a receive direction of a subscriber speech path and connect an intercept tone(S205). If a certain time passes, the ASC unit releases the intercept tone and re-connects the speech path(S206).

Title: Method For Selecting Dynamic Routing Using Routing Table
Inventor: LEE DONG WON
IPC: H04L12/28
Filed: 2001-12-29
Abstract: PURPOSE: A dynamic routing method using a routing table is provided to reduce a call failure rate and enhance a call connection performance by reducing a calculation amount for selecting a shortest path and a load over time. CONSTITUTION: Respective nodes give and take topology information periodically, calculate dynamic routing information, and stores it in a routing table(S401). A start node receives a call request from a signaling protocol(S402), analyzes a call request by performing a dynamic routing algorithm, and searches a destination node requested by a call(S403). The start node reads its routing table and obtains shortest path information to the destination node(S404). The start node checks whether the shortest path information satisfies such dynamic routing information as requested by the call(S405). If the shortest path information satisfies the dynamic routing information, the start node proceeds with the call through the shortest path according to the shortest path information(S406). If the shortest path information does not satisfy the dynamic routing information, the start node obtains the shortest path by performing a shortest routing dijkstra's algorithm(S407). The start node proceeds with the call through the shortest path according to the shortest routing algorithm(S408). It is judged whether the call has been successfully transferred to the destination node(S409). If the call has not been successfully transferred, the start node receives the call which returns with crank information(S410). The start node proceeds with the call with a newly set shortest path by performing the shortest path selection algorithm(S411).
