Abstract
A network access control is performed by using a status management table having a maximum permissible number of entries, which is determined depending on a time-out period predetermined by user terminals and a hardware-setting time required for setting communication resource. When receiving an access start request received from a user terminal, it is determined whether the hardware setting corresponding to the access start request is estimated to be completed within the time-out period. If it is estimated to be completed, the received access start request is registered into the status management table to issue a hardware setting command. If it is estimated not to be completed, an access rejection message is sent back to the user terminal.

A network access control apparatus in a code-division multiple access (CDMA) communications system including a plurality of user terminals, comprising:
- a status management table for managing a status of hardware setting corresponding to an access start request received from a user terminal;
- and
- an access controller for registering an access start request received from a user terminal into the status management table to issue a hardware setting command if the hardware setting corresponding to the access start request is estimated to be completed within a time-out period predetermined by the user terminal, and sending an access rejection message to the user terminal if the hardware setting is estimated not to be completed within the time-out period.
A network access control method in a code-division multiple access (CDMA) communications system including a plurality of user terminals, comprising the steps of:
- a) preparing a status management table having a maximum permissible number of entries, which is determined depending on a time-out period predetermined by the user terminals and a hardware-setting time required for setting communication resource;
- b) receiving an access start request received from a user terminal;
- c) when the status management table is not full, registering the received access start request into the status management table to issue a hardware setting command;
- and
- d) when the status management table is full, sending an access rejection message to the user terminal.
