Narrative:
Cleared to taxi to runway 30L via txwys Q, C, a. While taxiing out on taxiway C I noticed a B757 that had landed on runway 30R taxiing on runway 22. We were paralleling each other and I assumed he would turn into the ramp area behind me. Approaching taxiway a, ground told us to switch to 121.9. Then I heard someone say stop. By then I was entering taxiway a, I looked right and saw the B757, stopped. I continued on taxiway a. In retrospect, I missed the instruction to switch to the other ground control and thought I was cleared all the way to runway 30L. Suggest the frequency switch point be placed farther north and small signs be placed along the taxiway.
