User access adaptive scheduling method and device in TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) system

Abstract

The invention provides a user access adaptive scheduling method in a TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) system, which comprises the following steps: (1) a base station counts the total quantity of accessed users in a cell when the user access condition in the cell changes or at regular intervals; (2) the base station selects any one user from the accessed users in the cell and obtains the service speed of the user; (3) the base station recalculates the scheduling priority of the user according to the service speed and the user and the total quantity of current accessed users in the cell; (4) the base station judges whether a user whose scheduling priority is not recalculated exists, if yes, return to the step (2), or else execute the step (5); and (5) each accessed user in the cell is rescheduled according to the recalculated scheduling priority. The invention also provides a user access adaptive scheduling method in the TD-SCDMA system.

Description

technical field [0001] The invention relates to time division multiplexing synchronous code division multiple access (TD-SCDMA) mobile communication technology, in particular to a user access adaptive scheduling method and device in the TD-SCDMA system. Background technique [0002] In the existing TD-SCDMA system, there are three commonly used user access scheduling methods as follows: [0003] The first one is round-robin scheduling (Round Robin, RR), that is, according to the sequence of user access, the access users are scheduled sequentially. This scheduling method has high fairness but does not consider the capacity of the network. [0004] The second is the maximum bearer rate scheduling method (MAX-CIR, Maximal Carrier Interference Ratio). In this scheduling method, the priority of user access depends on the user rate, and the user with high channel quality and the highest supported rate is given priority. The user with the highest level and highest priority is sch...

Problems solved by technology

[0008] First of all, manually modifying the scheduling method requires staff to be on duty for a long time in front of the operation desk, constantly monitoring the network operation period, which is a waste of human resources; secondly, manually modifying the scheduling method is often unable to respond in time according to the actual network situation, resulting in the failure of the scheduling method. It does not adapt to the network conditions and affects the user experience
