Embodiment Construction

[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] figure 1 It is a schematic diagram of the method for guaranteeing application service QoS in the EVDO system of the present invention, as figure 1 As shown, in the present invention, for the upper layer application service between AT (access terminal, Access Terminal) and AppServer, the core network side identifies the service message through the DPI module, and identifies the messages of different application service types , figure 1 Different filling patterns are used to identify the different filling patterns. After the wireless side receives the application service message, it performs classification traffic statistics on the messages of different application services, so as to identify the current main application service of the user, that is, the main application service type. In this embodiment The middle is the busine...

Abstract

The invention discloses a method for ensuring quality of service (QoS) of application service in an evolution-data optimized (EVDO) system, which comprises the following steps of: carrying out detection and statistics on messages on a main connection single stream to identify the current main application service type of a user; carrying out the network resource allocation at the wireless side according to the QoS requirements of the current main application service types; and releasing the allocated network resources for the current main application service types when the allocated accumulated flow rate or the average speed exceeds the preset threshold. When the method is adopted, the QoS assurance can be provided for the application service of different transmission requirements, so the user experience can be greatly improved, and simultaneously, the system resources of the whole network can also be fully and reasonably utilized. The invention also discloses a device for ensuring the QoS of the application service in the EVDO system, which comprises a main service type identification module, a resource allocation module and a protection recovery module.

Description

technical field [0001] The present invention belongs to the technical field of communication, and in particular relates to a method and a device for guaranteeing user application service QoS (Quality of Service) in a CDMA2000 1x-EVDO mobile communication system (EVDO system for short). Background technique [0002] With the continuous popularization and development of mobile communication services, the CDMA2000 1x-EVDO wireless communication system is no longer only narrowly positioned as the function of carrying traditional business data such as file downloads and web browsing. For the carrying of increasingly rich and diverse application services, it also means that the wireless communication system is required to provide different Quality of Service (QoS) guarantees for different transmission requirements (bandwidth, delay) proposed by users for different application services. , but contradicting it is the limited network resources (bandwidth, connection) in the wireless ...
