Method and system for ensuring mobile network downward message QoS

Abstract

The invention discloses a method and a system for ensuring mobile network downward message Qos. The method comprises the following steps: step one: adding an IP message header to a message from a core network through an access network gate, filling a time stamp selectable field in the added IP message header according to the time that the message enters the access network, and transmitting downwards the message with the time stamp selectable field; step two: analyzing the time stamp selectable field through a base station, and dispatching the message according to the analysis result and the QoS parameters. The system comprises a core network, an access network gate, a base station and a terminal user. By adopting the above technical scheme, when transmitting downwards a message in a mobile network, the base station can dispatch the message according to the total delay of the message in the access network so as to more powerfully ensure the message Qos and to further improve the experience of the user.

Description

technical field [0001] The present invention relates to the field of broadband wireless access technology, in particular to a method and system for ensuring the QoS (Quality of Service) of messages delivered by a mobile network. Background technique [0002] In the mobile network, the network is divided into two parts: the access network and the core network. End users connect to the core network through the access network. The IEEE802.16 protocol family defines WiMAX (Worldwide Interoperability for Microwave Access, microwave access global interoperability ) protocol wireless access technology air interface standard, representative standards include IEEE802.16d fixed wireless access standard and IEEE802.16e mobile wireless access standard. The IEEE802.16 protocol family only defines technologies related to the wireless data link layer and the physical layer. Although the mobility characteristics of WiMAX are defined in IEEE802.16e, there is no standardization for large-scal...

Problems solved by technology

[0007] In the existing technology, when the core network delivers real-time service packets to end users through the access network, when the entire mobile network performs QoS guarantee, it can only count the traffic generated in a network element BS according to the respective methods of each equipment manufacturer. Packets wait for air interface scheduling delay and processing delay parameters, and according to the delay parameters through the priority algorithm to dispatch the message, the delay parameters and the statistics required by the IEEE802.16 protocol in the access network The total delay in the access network refers to the total delay from when the message initially enters the ASNGW to when the BS dispatches it. The existing technology ignores the time when the message passes through the ASN GW The resulting delay will inevitably pose a threat to the QoS guarantee of the packet, which will eventually affect the user experience
