Abstract

A system and method is provided for monitoring remote base station transceiver subsystems (BTSs) in a concurrent real-time operating system (CROS) environment in a code division multiple access (CDMA) or a personal communication service (PCS) system. The method includes the steps of transmitting remote control information including a designated identification (ID) to a target call control processor (CCP) from a source call control processor. A confirmation message is sent to the source CCP from the target CCP, when the designated ID of the remote control information matches control information associated with the target CCP. A remote control command is transmitted to the target CCP in accordance with the confirmation message. Response information is prepared in the target CCP in response to the remote control command. An inter-process communication message buffer is assigned as a print buffer for serial transmission of the response information, by controlling a shell of the CROS. The serial response information is outputted to an indicator device associated with the source CCP.

Claims

1. A method for monitoring remote base station transceiver subsystems (BTSs) in a concurrent real-time operating system (CROS) environment in one of a code division multiple access (CDMA) system and a personal communication service (PCS) system, said method comprising the steps of:

transmitting remote control information including a designated identification (ID) to a target call control processor (CCP) from a source call control processor;

sending a confirmation message to the source CCP from the target CCP, when the designated ID of the remote control information matches control information associated with the target CCP;

transmitting a remote control command to the target CCP in accordance with the confirmation message;

preparing response information in the target CCP in response to the remote control command;

assigning an inter-process communication message buffer as a print buffer for serial transmission of the response information, by controlling a shell of the CROS; and

outputting the serial response information to an indicator device associated with the source CCP.

2. The method of claim 1, wherein said sending step further comprises:

determining whether the designated ID of the remote control information matches the control information of the target CCP, when the remote control information including the designated ID is transmitted from the source CCP to the target CCP.

3. The method of claim 1, wherein the indicator device is a display.

4. A system for remotely monitoring base station transceiver subsystems (BTSs) in at least one of a code division multiple access (CDMA) and a personal communication service (PCS) system, the CDMA and PCS systems having a base station controller (BSC) network including BTSs and BSCs operating in a concurrent real-time operating system (CROS) environment, the system comprising:

a CROS of a source call control processor (CCP) for performing a remote control;

a CROS of a target CCP for receiving a remote control command having a designated identification (ID) from said source CCP;

an inter-process communication (ipc) message buffer for holding prepared response information in accordance with a result of verifying the designated ID of the remote control command and for being assigned as a print buffer; and

means for assigning said ipc message buffer as the print buffer to support a serial transmission of response information, the response information responsive to the remote control command.

5. The system of claim 4, wherein said CROS of the source CCP includes a shell for at least transmitting the remote control command.

6. The system of claim 4, wherein said CROS of the target CCP comprises:

a CROS kernel;

a user application block; and

a shell for interfacing said kernel with said user application block.

7. The system of claim 4, wherein said BSC network is arranged in a predetermined hierarchical order and, starting from a top of the hierarchy and progressing downwards, comprises:

a global communication interconnection network (GCIN);

a plurality of local communication interconnection networks (LCINs); and

a plurality of BTS communication interconnection networks.

8. The system of claim 4, wherein the base station transceiver subsystems associated with a respective base station controller (BSC) are controlled by a CCP associated with the respective BSC.

9. The system of claim 6, wherein said user application block uses primitives predefined by said shell.

10. The system of claim 6, wherein said shell interfaces a plurality of keyed-in debugging commands from a user to a routine processed by said CROS of the target CCP.

11. The system of claim 6, wherein said shell of said CROS of the target CCP transmits messages from remote BTSs and BSCs to a serial channel.

12. The system of claim 6, wherein said shell of said CROS of the target CCP analyzes commands inputted by a user.

13. The system of claim 12, wherein the commands are inputted by the user via a keyboard.

14. The system of claim 6, wherein said shell of said CROS of the target processor makes the remote control command operable, when a received message is confirmed as corresponding to the remote control command.
