No it doesn't mean a global frame. It means that the frame is not at the same location as the observed event. Like you measuring the speed of light near a black hole; in your clock and ruler it is a few meters/sec.

Sorry for being late on this thread. However, that is totally wrong. The speed of light near a black hole, or anywhere else, is the same. Deny that, and you're denying the foundation of Special and General Relativity.

Inside the black hole, the light doesn't escape because it is bent by gravity into a circle, and so doesn't escape, but its speed remains the same. Outside the BH, your clock will slow down and your ruler will shrink, nevertheless, you will end up measuring the speed of light to be c.

Suppose that you are outside gravitational fields, and that you have a clock and a ruler (which is not rotating with respect to stars), and that you are not accelerating. Based on your clock and ruler what is the measured speed of light near a black hole?

My favorite site: Speed of Light.
