Problems solved by technology

However, this method does not provide a certain QoS (Quality of Service) guarantee for the data communication of the specified priority, and the scheduling method is implemented and controlled by the base station, which treats all users equally, without considering the individual needs of users, and it is difficult to achieve differentiated services.

Embodiment Construction

[0054] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0055] Existing wireless communication systems (base stations and base station controllers) lack flexible resource scheduling methods when addressing users' individual needs. Once the user's service level is determined, it cannot be changed flexibly during business use, and it cannot meet the temporary needs of users to upgrade their service level and obtain higher wireless data rates in certain scenarios (such as handling emergency services).

[0056] Aiming at this technical problem of the prior art, the present invention proposes several embodiments of packet data service priority scheduling methods, such as figure 1 As shown, it is a schematic diagram of a network structure of an application scenario of an embodiment of the packet data service priority scheduling method of the present invention. The application sc...

Abstract

The invention relates to a packet data service priority-scheduling method, which comprises the following steps that: an authenticated billing center receives service class promoting indication information sent by an access terminal; the access terminal is authenticated, and service class update is carried out after the authentication is passed; the updated service class information is sent to access network equipment through a service gateway; and the access network equipment calculates wireless scheduling parameters according to the updated service class information and carries out priority scheduling operation to the access terminal according to the wireless scheduling parameters. The invention also relates to a packet data service priority-scheduling system. When the system provides a packet data service for a user, the system provides a priority service request based on a user demand and a scheduling function. When the user needs the service quality of higher rate, the system can automatically issue a higher priority service request, and the access network equipment can carry out scheduling of a higher priority level for the user during wireless resource allocation according to the service class applied by the user, so that the best rate priority security is realized, and the corresponding billing is completed.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for priority scheduling of packet data services. Background technique [0002] With the continuous increase of people's demand for mobile data services, the ability of mobile communication systems to support high-speed data is also continuously enhanced. For example, EV-DO, the evolution version of CDMA2000, is designed for the mobile communication system to support high-speed packet transmission capability, and can provide a forward peak rate of 3.1Mbps. According to the characteristics of data services, the EV-DO system adopts the rate control technology. The mobile station measures the pilot C / I once in each time slot to predict the highest transmission rate that can be supported, and through the reverse DRC (Data Rate Control) Channels are reported to the base station. Based on the information fed back by each mobile station, the base statio...
