Problems solved by technology

[0006] It can be seen that in the scheduling method provided by the prior art, when scheduling services with continuous data transmission and small data volume, it may cause insufficient control channel resources, but waste service resources, and increase the number of users with poor channel environment and large buffer capacity. The packet loss rate, thereby reducing the throughput of the system

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0029] figure 1 It is a flowchart of an embodiment of a scheduling method provided by the present invention. Such as figure 1 As shown, the method includes the following steps:

[0030] Step 101, in the current scheduling cycle, determine the priority of the priority queues (PQ) to be scheduled in the scheduling list, and sort the PQ queues to be scheduled according to the order of priority from high to low.

[0031] In practical applications, priority queues are usually called PQ queues.

[0032] In addition, each scheduling cycle is provided with a scheduling list, which stores PQ queues to be scheduled and users to be scheduled corresponding to the PQ queues. One user to be scheduled can correspond to one or more PQ queues. The m...

Abstract

The invention discloses a scheduling method. In the method, after the number of idle control channels is less than or equal to the threshold value of rest control channels, PQs (Priority Queues) which meet a condition that the data size of service cache is equal to or more than the quotient between a bit number capable of being loaded by rest idle resources in a current scheduling cycle and the number of the idle control channels are searched according to a descending order of the priorities of the PQs; and further, a first one of the searched PQs which meet the condition is scheduled. With the adoption of the method disclosed by the invention, the throughput of a system can be enhanced.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a scheduling method. Background technique [0002] The HSPA+ system is an optimization and upgrade of the High Speed ​​Downlink Packet Access (HSPA) system. The peak rate of the HSPA+ system is significantly increased, and the types of packet services supported are more diverse. The HSPA+ system adopts many enhanced measures in the media access control (MAC) layer to try to meet the quality of service (QoS) requirements of different services, such as the use of flexible radio link control protocol (RLC) protocol data unit (PDU) size, in order to Reduce the restrictions on the transmission of large data volume services, or multiplex queues with different priorities for transmission, so as to reduce the waste of resources for services with small data volumes. In addition, the HSPA+ system also adopts the semi-static scheduling (SPS) technology to specifically support services t...
