Human Factors
ATC repeatedly called us by wrong call sign. Company [flight] XXXX was in front of us. ATC kept calling us XXXX.
Descending on the ROKKR 1 we [flight XXYX] were given continued descent to 7000 FT. Flight XXXX was also on frequency; SoCal [Tracon] seemed to be mixing up the call signs or we may have misheard them. It is possible our clearance to 7000 FT was meant for XXXX. Several times it sounded like SoCal called us XXXX or called them XXYX. Somewhat urgently; we were directed to stop our descent immediately; which left us at 10;100 FT; which we reported. Then we were given vectors for traffic and then a second traffic. Normal vectors to final and continued descent followed.
B737 flight crew reported ATC repeatedly assigned instructions to incorrect aircraft due to similar call signs.
