Abstract: A front light source module is provided to include a side light source; a light guide layer with a light incident side opposite to the side light source in a first direction; and a first light adjusting layer, the first light adjusting layer and the light guide layer are stacked in a third direction, a portion of the first light adjusting layer away from the light guide layer is provided with micro-groove structures, each including: a first inclined surface and a second inclined surface opposite to each other in the first direction, the first inclined surface is configured to face the light incident sid, closer to the light incident side than the second inclined surface, angle ? between the first inclined surface and a plane where a surface of the first light adjusting layer away from the light guide layer is located is in a range from 26° to 42°.

Abstract: Example methods, devices, and apparatuses are discussed. An example method includes determining that a condition associated with triggering a registration procedure is satisfied. The condition comprises that a second tracking area (TA) supports a first slice. The second TA belongs to a current registration area (RA) of the terminal device. The first slice is rejected in the current RA, wherein the terminal device is in the second TA. The example method further includes,n response to the determination, sending a second registration request message to a core network device. The second registration request message requests to access the first slice. The second registration request message comprises information about the first slice.
