Abstract

The invention discloses a safe shunting uplink transmission time optimization method based on a linear search mode. The method comprises the following steps: (1) there are a total of 1 mobile users under the coverage of the base station, which satisfies the mobile subscriber's quality of service and ensures the user's transmission information security while the uplink transmission time of amobileuser is minored, wherein the optimization method is a non-convex optimization problem; (2) a P1Sub-UP problem is equivalently converted to a P1Sub-UP-E problem, the P1Sub-UP-E problem is equivalent toa P1Sub-UP-E-Bot bottom-level problem and a P1Sub-UP-E-Top top-level problem; (3) a P1Sub-UP-E-Bot-althorigm of the P1Sub-UP-E-Bot problem is solved. In order to determine whether the P1Sub-UP-E-Botproblem is viable or not in the condition that iB is belonged, a P1Sub-UP-E-Top problem is proposed. Based on a linear search method, overall wireless resource consumption is optimized under the condition that the upload amount of a mobile user is given. The present invention minimizes uplink transmission time.totally I mobile users exist in the coverage range of a base station, the service quality of the mobile users is met, the uplink transmission time of the mobile users is minimized while the transmission information security of the users is ensured, and an optimization problem is described as a non-convex optimization problem; (2) carrying out P1Sub-treatment on P1Sub- Equivalent conversion of UP problem to p1Sub- UP E, performing problem treatment on P1Sub- UP E problem is equivalent to P1Sub- UP E Bot underlying problem, P1Sub- UP E Top top layer problem; (3) solving P1Sub- UP E Algorithm P1Subb-for Boot Problems UP E Bot Algorithm, in order to judge P1Sub-under the condition that a given value belongs to iB, uP E Proposing whether the Boot problem is feasible or not, and proposing P1Sub- UP E Top problem; based on a linear search method, the overall wirelessresource consumption is optimized under the condition that the uploading amount of the mobile user is given. The present invention minimizes uplink transmission time.
