Abstract:
1. A method for sending service information, the method comprising: asynchronously receiving, at a first terminal, service information and a current adaptive coding and modulation (ACM) profile identifier (profile ID) sent by a remote terminal; judging whether the received current ACM profile ID is consistent with an ACM profile ID recorded in separately-stored coding and modulation information within the first terminal, wherein the separately-stored coding and modulation information comprises the recorded ACM profile ID which was used for successfully sending service information last time and a corresponding coding and modulation scheme; when the received current ACM profile ID is consistent with the recorded ACM profile ID, coding and modulating the service information according to the coding and modulation scheme recorded in the coding and modulation information; when the received current ACM profile ID is inconsistent with the recorded ACM profile ID, searching and invoking a coding and modulation scheme corresponding to the received current ACM profile ID from an ACM profile table stored in the first terminal, and coding and modulating the service information according to the invoked coding and modulation scheme; and sending the coded and modulated service information, wherein the coded and modulated service information carries the received current ACM profile ID.
