Embodiment Construction

[0023] The invention will be described in more detail hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. In the drawings, the same reference numerals denote the same or similar components or elements.

[0024] figure 1 It is a flowchart of a packet scheduling method 100 for a packet data transmission system according to an embodiment of the present invention.

[0025] In step 102, according to the requirements of different services on QoS parameters, the forward service flows belonging to each AT (access terminal, access terminal) are separated into different priority queues, and the priority queues include the highest priority queue, secondary High-priority queue, next-lowest-priority queue, and lowest-priority queue.

[0026] In step 104, strict priority scheduling is performed on access terminals in the order of the highest priority queue, the second highest priority queue, the second lowest priority q...

Abstract

The invention provides a packet dispatching method and a forward service dispatcher, relating to the field of communication. The packet dispatching method comprises the steps of: separating a forward service stream belonging to an access terminal to a top priority queue, a secondary top priority queue, a secondary lowest priority queue and a lowest priority queue according to the requirements of different services on QoS (quality of service) parameters; carrying out strict priority dispatching on the access terminal according to the sequence of the top priority queue, the secondary top priority queue, the secondary lowest priority queue and the lowest priority queue in each dispatching time slot; carrying out dispatching on the packet data of same priority queue in different access terminals by adopting a time slot polling method when a base station processes the packet data of the top priority queue, the secondary top priority queue and the secondary lowest priority queue of the access terminal of a sector to which the base station belongs; and carrying out dispatching on the access terminal by applying a proportional fair dispatching method when the bases station processes the packet data of the lowest priority queue of the access terminal of the sector to which the base station belongs. The invention provides supports for the packet and dispatching for differentiation QoS.

Description

technical field [0001] The invention relates to the communication field, in particular to a packet scheduling method and a forward service scheduler. Background technique [0002] EV-DO (evolution data only, evolution for data processing) is an enhanced technology of CDMA2000 1x. It is a wireless transmission technology optimized for mobile data applications, and is more suitable for the needs of 3G multimedia services. At present, operators around the world have launched content-rich multimedia applications on EV-DO, such as mobile VT (videotelephony, video telephony), PTT (push to talk, push to talk) services, VoIP (voice over Internet protocol, VoIP), BCMCS (broadcast and multicast services, broadcast multicast service), wireless broadband access and streaming media and other services. At the same time, the number of mobile users continues to grow rapidly, and more and more users will enjoy the brand-new service experience brought by the 3G network. Therefore, how to eff...
