Embodiment Construction

[0044] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] figure 1 It is a flow chart of the business scheduling method of the embodiment of the present invention, such as figure 1 As shown, the service scheduling method in the embodiment of the present invention includes the following steps:

[0046] Step 101: According to the transmission delay parameter C of the service queue Td , The scheduling priority indication parameter C of the business queue SPI and user terminal scheduling related parameters C UE At least one of them determines the priority of the service queue to be scheduled.

[0047] The scheduling method in the embodiment of the present invention comprehensively considers the channel conditions of the terminal, the delay characteristics of the service queue, the guaranteed bit rate (GBR, Guaranteed Bit Rate), the priority level of the service queue, etc., and meets the use...

Abstract

The invention discloses a service scheduling method, which relates to service scheduling in a wireless communication system, and is proposed for solving the problem that services in prior service queue scheduling are irrational. The service scheduling method adopts a scheme comprising: according to at least one of transmission time delay parameters C of service queues, scheduling priority indication parameters C<SPI> of the service queues and user terminal scheduling related parameters C<UE>, determining the priorities of the service queues to be scheduled; and allocating physical resources to the service queues to be scheduled according to an order from the high priority to the low priority, and performing queue scheduling. The invention simultaneously discloses a device for implementing the method, which comprises a priority parameter calculation unit used for determining the priorities of the service queues to be scheduled, and a physical resource allocating and scheduling unitused for allocating the physical resources to the service queues to be scheduled according to the order from the high priority to the low priority, and performing the queue scheduling. In the invention, the determined priorities of the service queues fully guarantee the QoS of the services and improve the performance of the service scheduling.

Description

technical field [0001] The present invention relates to a service dispatching technology in a wireless communication system, more specifically to a service dispatching method and device in a High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) system. Background technique [0002] Future wireless cellular networks will support integrated multimedia applications with different QoS (Quality of Service) requirements. Providing QoS differentiation is considered to be a good solution to the increasing multimedia demands of wireless end users. In the HSDPA system, a high-speed downlink shared channel is shared by multiple users in the same cell. There are differences in service characteristics between multiple users, and a single user may simultaneously transmit several service data with different QoS requirements. For example, a user can browse video streaming media while downloading via FTP (File Transfer Protocol). Therefore, the scheduler in the N...
