Method for Call Traffic Management in Asb of Cdma 1X System

Abstract

The present invention relates to a method for processing call traffic in an ATM Switch Block (ASB) in a CDMA 1x system. The CDMA 1x system comprises a Base Transceiver System (BTS), which comprises an OA, a High-speed Transfer and Selector Block (HTSB), an ATM Switch Block (ASB), an ATM Traffic Block (ATB) and a MMCA, and a Base Transceiver System (BTS), which is coupled to a Call Control Processor (CCP). When a request for call setup is transferred from the BTS to the CCP, a traffic path between the OA and the MMCA is set up through performing the claimed method. The present invention removes unnecessary traffic paths so as to utilize system resources efficiently while optimizing system performance.

BEST MODE FOR CARRYING OUT THE INVENTION

The method for processing call traffic in an ASB of a CDMA 1X system according to an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a functional block diagram for implementing a method for processing call traffic in an ASB of a CDMA 1X system according to an embodiment of the present invention. An apparatus for implementing the method for processing call traffic in an ASB of a CDMA 1X system according to an embodiment of the present invention comprises Base Transceiver System (BTS; 500). The BTS 500 comprises Operations Application (OA; 410), High-speed Transfer and Selector Block (HTSB; 400), ATM Switch Block (ASB; 200), ATM Traffic Block (ATB; 300) and Multi-rate Channel Card Assembly (MMCA; 510), and Base station Control System (BCS), which comprises Call Control Processor (CCP; 100).

The method for processing the call traffic in an ASB of a CDMA 1X system with the above-described structure is described below with reference to FIG. 2.

The CDMA 1X system comprises BTS (500), which comprises OA (410), HTSB (400), ASB (200), ATB (300) and MMCA (510), and BCS, which comprises CCP (100). As shown in FIG. 3, when a request for call setup is transferred from BTS (500) to CCP (100), a traffic path between OA (410) and MMCA (510) is set up according to the following steps:

ASB (200) receives a request for traffic connection setup from CCP (100) (S1).

ASB (200) connects a path of OA (410) and a path of MMCA (510) individually and independently (S2).

ASB (200) reports completion of traffic setup to CCP (100) (S3).

On the other hand, in a CDMA 1X system comprising BTS (500), which comprises OA (410), HTSB (400), ASB (200), ATB (300) and MMCA (510), and BCS, which comprises CCP (100), as shown in FIG. 4, when a request for call release is transferred from BTS (500) to CCP (100), a traffic path between OA (410) and MMCA (510) is released according to the following steps:

ASB (200) receives a request for traffic release setup from CCP (100) (S1).

ASB (200) releases a path of OA (410) and a path of MMCA (510) individually and independently (S2).

ASB (200) reports completion of traffic release to CCP (100) (S3).

INDUSTRIAL APPLICABILITY

As described above, the method for processing call traffic in an ASB of a CDMA 1X system according to the present invention removes unnecessary traffic paths so as to utilize the system resources efficiently while optimizing the system performance.

Further, according to the present invention, the traffic path setup is managed by an ASB, thus leading to shorter path setup time. The present invention removes the paths upon call release to reuse and make the most of the system resources.
